Season Three

  1. The Two (OAD 09/28/03)
    Sydney is where we last left her, in a Hong Kong safe house. Vaughn tells her she's been gone for two years. Will survived the apartment fire, he says, but she died and her remains were identified. Vaughn's now a teacher, but the CIA sent him to take her back. Syd attacks Vaughn and escapes the safe house. She fights two CIA agents standing guard and Vaughn finally brings her down with a dart.

    She wakes in the Stafford Naval Hospital. Dixon is there; he's now director of their division. Weiss calls Dixon away — he says Agent Scott Kingsley has the chip and is on a train to Avignon. He says the Covenant is moving to intercept and get the chip. A lead has placed a Covenant outpost outside Paris. Dixon returns and reveals that Jack has been in solitary for a year, courtesy of NSC Senior Director Robert Lindsey.

    On train in Lyon, France, a gunman shoots and kills Kingsley. He finds the chip. It shows the schematics for an undetectable spy drone that, the CIA believes, could be used as a bio-weapon delivery system.

    Sydney sees Marshall and Carrie, who is pregnant. In a meeting, Syd tells Dixon she was held captive in The Covenant's Paris base and heard Kingsley's name. Kingsley is just one of eight recent murders of CIA agents. Lindsey's adamant that Sydney go on this mission. Syd agrees on the condition that she gets to see her father. Lindsey agrees.

    Syd tells a handcuffed Jack, who's been charged with resisting authority for contacting Irina (#6 on the CIA Most Wanted List), that she lied about The Covenant's Paris outpost in order to see him. He urges her to regain her CIA clearance and continue his research into her disappearance. He knew she was alive and has evidence. He also tells her that Vaughn isn't worthy of her grief.
    In a Paris hangar, Weiss leads Syd and small team looking for the chip. They are attacked. Weiss is knocked unconscious and his throat about to be slit by the man on the train. Syd saves him. She admits she was lying and now if she goes back, her clearance will be pulled. Syd must identify this man. Weiss advises her to see Sloane, who now runs the World Health Org. in Zurich and is a consultant for the CIA.

    She barges into Sloane's office. He was expecting her and identifies the man — Gordei Volkov — a Russian hitman. Blaming him for her predicament, she threatens to kill Soane. He says he's been redeemed, that the Rambaldi device delivered a message of peace. He then gave the CIA info to dismantle two dozen terrorist cells. Syd doesn't buy it.

    Finding an old contact, Syd discovers Volkov has a meeting in Prague. She ambushes him, blows up his car. In the ensuing melee, Syd stabs him and retrieves the chip as he dies. She returns to Lindsey, threatening to destroy the chip unless he releases her father. He acquiesces.

    Vaughn meets Syd. She's angry with him for looking for closure. She says she would have had faith and waited. But now she realizes it would have been an absolute waste if she had.

    Jack returns to the CIA and takes Syd to a storage room. He shows her videotape of a Russian diplomat named Andrian Lazarey. On the monitor, a blonde Sydney stabs the man in the neck, killing him.
     
  2. Succession (OAD 10/05/03)
    In Berlin, a helicopter lifts an elevator carrying two CIA agents out of its shaft. Satisfied that Syd is not brainwashed, Jack dissuades her from admitting to the CIA that she killed Lazarey. Later, Weiss helps Syd move in to a neighboring apartment. He says that Vaughn was reluctant to return to the CIA.

    The team learns The Covenant, a loose affiliation of Russian nationals, is behind the kidnapping. They will execute the men unless their demands are met. Syd volunteers to retrieve a package in a Munich adult movie theater. Dixon informs Syd of a therapy group for those who have lost their memory. Jack tells Syd that she was cremated and Vaughn spread her ashes at sea.

    In the theater, Syd opens the package — it's the head of one of the CIA agents. Shoved in his mouth is a note demanding the the CIA exchange Sark for the remaining agent. Syd objects but Lindsey says Sark has no more secrets and, based on info provided by Sloane, believes they want to kill him.

    Syd visits Vaughn at his classroom; he's a French teacher. She tells him she could cope with his return to the Agency. After her death, Vaughn says, he lost control and started drinking. He was deeply in love with her, but he doesn't regret moving on with his life.

    Jack confronts Sloane, doubting his redemption and blaming him for Syd's disappearance. Jack offers to stop his efforts to invalidate Sloane's pardon if he gives details. Sloane gives Jack a disc with his own leads into Syd's death. Despite Sloane's denials, Jack says he'll bury Sloane for his involvement.
     

    In a CIA jail, Sark denies knowledge of Syd's death. At the exchange in the Sonora desert, Sark is unsure why The Covenant wants him. The trade is interrupted by a Lindsey-ordered Delta Force helicopter. In the confusion, Sark and the CIA agent, a scientist, are taken by the Covenant. Syd later threatens Lindsey in the men's room for pulling that stunt. A man named Ushek San'ko says that Sark killed his brother, and demands $800 million. He says Sark, unbeknownst to him, is worth that much. Vaughn is reinstated while Jack discovers that Sark and San'ko withdrew $800 million in gold bullion from a Grand Cayman bank. The money belonged to Lazarey, a murdered Russian diplomat and descendant of the Romanov family. When he died, it went to his son … Mr. Sark.

    Weiss tracked the scientist to a Frankfurt nightclub, run by Otto Edel, a drug dealer. Jack believes The Covenant is responsible for Syd's two year absence and compelled her to assassinate Lazareey. He's contacts Irina, who offers her help.

    At the club, Syd poses as a chemist offering to triple Edel's sales by making his drug more addictive. She threatens to overdose him, but he locates the alarm terminal. Vaughn remotely helps her deactivate the alarm. Syd opens the torture room where the scientist is held, shoots the torturer. The dying torturer remembers her, said she kept her promise to kill him. He says that she was his favorite because she never broke.

    At therapy, others discuss their amnesia and ensuring nightmares. Syd later interrupts Dixon to tell him that although she still has feelings for Vaughn, she won't be a part of the group. Dixon introduces Syd to the woman to whom he was speaking, Lauren Reed, the new NSC liaison, who'll be investigating Lazarey's murder. She's Vaughn's wife.
     

  3. Reunion (OAD 10/12/03)
    A fireball drops from the sky, devastating Moscow's Gorky Park. At the CIA, Dixon explains the fireball was a falling satellite and that it nearly prompted a nuclear response from Russia. Echelon picked up a call between Sark and Boris Oransky, an employee at a French firm that built the satellite. He and Sark discussed moving to "Phase 2." Sark has been tracked to a Mexico City hotel. Dixon orders a team to follow him. Syd believes they should apprehend him and argues with Lauren. Vaughn defends Lauren, saying that capturing Sark will do nothing to shut down The Covenant. Later, Vaughn asks a furious Lauren to give Syd the benefit of the doubt.

    Jack tells Syd that the NSC has murky footage of Lazarey's murder. He again tells Syd not to admit her guilt because of the dangerous techniques the CIA would use to extract her memories. Jack views the tape with Lauren and Marshall, who requires 72 hours to make the tape clear for identification.

    In Mexico, Syd, disguised as a Gaucho, locates Sark and Oransky in a cafe. Oransky gives Sark photos and codes, and mentions the word "Medusa." Sark leaves and Syd is discovered by Oransky's thugs. Oransky takes a hostage and forces Syd to drop her gun. Marshall determines the frequency of Oransky's earpiece and pushes 180 decibels of feedback through it. Syd attacks the thugs but Oransky escapes.

    Syd tells Weiss she remembers something about Medusa at SD-6. Weiss tells a curious Syd that Vaughn met Lauren when she deposed during the investigation into Irina's mother.
     

    Dixon discovers that Medusa was an SD-6 project. It's an anti-satellite weapon that can cripple a network of satellites. Oranksy destroyed the Russian satellite to discover their protocol for nuclear attack. The pictures Syd took reveal a motorcade to the Russian Science Ministry, where Medusa is stored. Russia claims not to have anti satellites so the CIA must get to it before Sark. Despite Syd's protests, they decide Sloane can help them get into the Science Ministry.

    Syd, Vaughn and Lauren travel to Zurich, where Sloane — who has a relationship with the Ministry due to his cancer research — refuses to help them. But after Syd threatens him, he agrees to admit them to a Ministry banquet. Sloane taunts Vaughn and Lauren.

    Meanwhile, Jack bribes computer expert Pierre Lagravanese to corrupt the image of Lazarey's murder. Jack's given a virus, which he must upload to a terminal with administrative privileges. He installs the files.

    At the Ministry, Syd and Vaughn once again feel an attraction. Vaughn creates a diversion, allowing Syd, who's stolen a diplomat's fingerprints, to gain them unrestricted access. In an elevator, they change into Russian military uniforms. Down in the bunker, Sark has murdered the guards. Marshall and Dixon watch Lazarey's murder as Jack is corrupts the files. The image won't render.

    Syd and Vaughn engage in a firefight with Sark. He locks them in a sublevel and disconnects the elevator. Oransky goes after Syd while Sark bolts. Syd and Vaughn rig the generator to blow and crawl out intake vent as Oransky is killed and Medusa is destroyed. Weiss gives her a 3rd edition of Alice in Wonderland, a favorite of Syd's that was destroyed when her apartment burned.
     

  4. A Missing Link (OAD 10/19/03)
    As Syd and Jack view the tape. Lazarey says "Julia" before he dies.

    A team stole four vials of Ebola from a French epidemiology lab. Lauren and Syd question Laszlo Bogdan, a team member who was infected and captured. He says The Covenant plans to mutate the virus … and his team was set for a second heist. Dixon IDs the team, led by a deadly freelancer named Simon Walker. Syd is to pose as a security expert, join Walker's team and track whatever they steal back to The Covenant.

    A flirtatious Vaughan gives Syd a lipstick tracking device. In Sevilla, a disguised Syd meets Walker. He calls her Julia and greets her with a hot kiss. He says he's missed her. Syd is coy and says she wants to work with him again. "What, no future in murder?" he asks. Meanwhile, Syd meets the crew. They test her by making her steal a 150 carat diamond necklace from Princess Demetria of Greece. Walker gives her a tranquilizer gun and a knife, then calls the police. She has seven minutes to do it.

    Dressed as a maid, she dopes the guard and enters the suite. The princess is sleeping; Syd dismantles a phone, creating an amplifier, and cracks the safe containing the necklace. As the police arrive, she darts the princess and jumps out the window into a pool far below. She returns to Walker with the necklace.

    On the plane home, Vaughn, who had heard the whole thing, asks her what "Julia" was all about. She's mum, admitting she can't trust him because of Lauren. At the CIA Jack says Vaughn has been snooping. Syd considers admitting her guilt.
    Marshall creates a safecracking device for Syd. Dixon calls a meeting with Syd, Jack and Vaughn. Jack has shown him the video of Lazarey's murder and told him Syd was conspiring to keep it a secret. Dixon is displeased but says that she was not responsible. He prohibits Vaughn from mentioning this to Lauren. Syd realizes Jack manipulated the situation so the NSC, ie., Lauren, wouldn't find out. Later, Syd apologizes to Vaughn.

    In Spain, Walker receives pictures of Syd and Vaughn. Syd returns to Walker, and as they kiss she tries to extract info — she learns they met in Algeria. But the game is up and he puts a knife to her throat and shows her the photos. She says Vaughn is her supplier. Vauhgn calls Marshall, telling him to create a criminal record for himself on Interpol, which he does just before Walker checks it.

    The team plans to go to a storage facility 35 miles outside Ibiza, run by disease control ministry. They'll have five minutes to get the package, a temperature-sensitive biological element. Sark walks into the safe house to talk about the deal! Syd manages to elude his notice. Lauren tries to pry info about The Covenant from Sloan. He says that they'll be able to create a bio-weapon against specific targets with the new theft. Sloane baits Lauren, says she in her job because of her father, a Senator.

    Walker and Julia break into the facility's refrigerated vault. Syd has about a minute to crack the safe, but Marshall's device won't work. She reroutes the hardware and breaks in before the temperature rises too high. They steal the canister and put it in a cooler. As they switch vehicles, Syd grabs the transmitter from the lipstick. Vaughn is in the other vehicle! They've discovered he's CIA. To gain some control over the situation, Syd stabs him in the ribs. Walker then kicks him down a hill and they leave in a new vehicle.
     
  5. Repercussions (OAD 10/26/03)
    A frantic Sydney phones Jack, telling him to activate the transmitter that she put on Vaughn. Later Syd breaks into Simon Walker's room only to find the bio-weapon gone; he has sold it to Sark. He kisses her and they part.

    Weiss finds Vaughn. As he recovers in the hospital, Syd tells Lauren that she stabbed him in order to save him. Lauren is incensed. The CIA picks up an aircraft in the Ural Mountains deploying the bio-weapon against a prison. They notice Sark extracting the sole survivor — Abasi Bomani, the largest arms dealer in Africa. The Covenant tailored the weapon to spring Bomani.

    Since Sloane had turned in Bomani years ago, the CIA decides to tap him for more info. On the plane to Mexico City, Lauren pressures Syd to transfer to another field office. Syd is defiant. As they enter Sloane's building, he's kidnapped before their eyes; forced into a van by Sark and Bomani. Sloane, trying to prevent his torture, says he can legitimize Bomani.

    Lauren apologizes for threatening Syd. Later, Vaughn dreams of Sydney kissing him, then stabbing him. He wakes to find Lauren at his side.

    Sloane returns to the CIA, says Bomani let him go in exchange for info — his Yakuza contacts have developed an AI computer virus that probes networks and writes itself. It can crash markets, ruin banks, paralyze the military. He wants the CIA to disable the virus, but not destroy it. If Bomani finds it destroyed, he'll kill Sloane, who suggests he's now valuable as a double-agent working for The Covenant but loyal to the CIA. Syd is dubious but Marshall's lie-detector tests verify Sloane's sincerity.

    Jack, posing as a potential client, meets Simon in Paris in order to learn more about Syd's past. Javier IDs Jack and tells Simon that his daughter is Syndey Bristow, alias Julia Thorne. Simon baits Jack, who ultimately murders him when he refuses to divulge any info.

    Marshall must see the code in order to render the virus harmless, so he's chosen to go with Syd. They enter the Osaka casino dressed as a cowboy and his floozy. He joins a blackjack table and cleans up, thanks to his skillful cheating. Allowing himself to be caught, he and Syd are taken to a back room. With Marshall's hands about to be cut off, Syd leaps into action. Together, they handle the thugs. Marshall breaks into the system and disables the virus just before Sark and Bomani enter the casino. They hide as Sark transfers the useless code to his server.

    Mission completed, Syd visits Vaughn in the hospital, where she happens upon Lauren tenderly kissing Vaughn.
     

  6. The Nemesis (OAD 11/02/03)
    Sloane tells Syd that intel about The Covenant's next move is encoded in an image of the Vatican on a web site. She says that he'll never have her trust or Jack's friendship.

    At the CIA, Dixon says The Covenant is after device that can interface with Russia's launch control, given them access to their nuclear arsenal. Its designer, Robert Lang, altered his appearance and is on the run. He is to retrieve new identity papers from Heinrich Strauss at a Milan nightclub. The Covenant wants to grab Lang and the device. Dixon assigns a reluctant Syd to be Sloane's handler and says Allison Doren is alive. An unnerved Syd later says she will kill Allison.

    Sark meets Allison in Strassburg, rekindling their love. Allison explains that The Covenant found her and Syd after their fight. She recovered in 6 months and has been working for them since. Sark says will find his father's murderer and Allison swears Syd will pay for her scars.

    Lindsay tells Lauren that a Russian government source has info that could lead to Lazarey's murder and that The Covenant has moles in the Russian government. He swears Lauren to secrecy and sends her to meet the source in Moscow. Lauren lies to Vaughn about the trip. He gives Lauren a database of Lazarey's phone calls, suggesting the murderer may be traced through calls.

    In Milan, Syd is disguised as a Euro clubber. Vaughn uses a Marshall-made mini x-ray camera, rigged via Syd's necklace, which can spot facial reconstruction. Sark and Allison appear. Lang retrieves his papers and bolts when Allison kills Strauss. They all chase Lang, but Allison finds him first and extracts a tooth before killing him. Syd discovers the body, whereupon Allison knocks her unconscious.
    Back at the CIA, the x-ray images of Lang's tooth reveal a filling that is a Radio Frequency Identification chip. Lang used the chip to open the launching device. Lauren discovers a call from Lazarey's murderer and tracks it, through voice analysis, to the London address KNG Microtech. The office is empty but Lauren discovers it was leased to Julia Thorne.

    Syd forces Sloane to meet with Sark and Allison in Prague and get them to divulge the location of the device. Using his cover as a double-agent, Sloane coaxes Sloane to admitting the device is in a vault in Sophia, Bulgaria. Syd makes Sloane ask about her past. Allison says The Covenant ordered her not to kill Syd because they want to retrieve something her memory. This makes Syd want to undergo CIA memory retrieval, which Jack vehemently opposes.

    Dixon sends Vaughn and Syd to Sofia. He privately admits to Syd that he wants Allison dead because she murdered his wife. Using a tracking device, Syd and Vaughn find Allison in an abandoned building in Sofia and give chase. Allison corners Syd and says that Syd had discovered a formula for a medication in the Rambaldi journal — which was ultimately used to heal Allison's wounds. Syd grabs Allison's gun and shoots. She alive, but barely. They find the device on her body.

    Syd's suspicions are raised when Vaughn knows nothing about the formula. They find the ambulance overturned, the medics dead and Allison missing.
     
  7. Prelude (OAD 11/09/03)
    Syd wakes from a nightmare in which she sees an angel-like figure, then pulls strange tubes from her mysterious scar. Shaken, she asks a CIA psychiatrist about the memory-retrieval procedure. The doctor shows her Kenneth Blake, a man whose memory was retrieved at the cost of his sanity.

    The Mexican police capture Simon's lackey Javier, who offers up info about a CIA agent used by terrorists to kill a Russian diplomat.

    At the CIA, Sloane says The Covenant wants him to attend a Chinese governmental function in order to steal data. China intends to mount a microwave laser on a satellite as an assassination weapon. It would make the victim appear as if he died of natural causes. He wants Syd to accompany him and corrupt the data. Syd will access the motherboard, connect to Marshall, who will corrupt the system.

    Vaughn and Lauren travel Mexico to interview Javier. Jack advises Vaughn to impede the investigation. Vaughn disagrees, saying Lauren is their best chance to keep Syd's secret from NSC.

    Syd and Sloane attend the Beijing ball posing as lovers. Syd secretly assembles a toy car controlled by Marshall, which he uses to follow a guard to the security system. Sloane persuades Syd to dance for the sake of their cover. Marshall shuts down the system. Syd gladly slaps Sloane in order to give the impression they're having a lover's spat.

    Meanwhile, Jack has bribed the Mexican police to detain Vaughn and Lauren. When they're released, they find Javier dead in his cell, an apparent suicide victim. Vaughn tells Jack if he ever puts his wife in danger again, he'll kill him. Jack tells Vaughn that maybe now he understands the compromises one makes when a loved one is in danger
    Syd finds the vault, retrieves the case and connects to it, allowing Marshall to corrupt the code. The guards repair the security system and spot Syd. She fights off the guards as Marshall finishes his job. Afterward, Sloane says the day she was found in Hong Kong, he received a letter in Syd's handwriting, address to Sydney Bristow. He gives it to her. A key and paper fall out. It's a series of numbers, a code.

    Sark pays a visit to Lauren. He says that he had planned for Javier to be extradited and forced to confess the identity of Lazarey's murderer. He gives her a dossier, which includes a picture of Lazarey and Julia Thorne. Sark identifies Thorne as Sydney.

    Jack looks at the note Sloane gave Syd. He says the cipher text was devised by Irina. It's the address of a penthouse in Rome.

    Vaughn and Lauren argue about keeping Sydney's secret. He says Dixon ordered him not to divulge anything, but she'll have none of it. Vaughn says Lindsey will ship Syd off to Russia if he finds out. Lauren admits that she's already reported Syd. Vaughn then tells Syd everything and arranges for her to fly to Rome and pick up a new passport.

    Syd asks him why he's helping her. He says some things don't change. "I'm not going to lose you twice," he says, and they hug. Later, Vaughn tells Jack he'll do anything to help Syd.

    Under Lindsey's authorization, Lauren takes control of the task force from Dixon, relieving him for "obstruction of justice."

    Syd enters her apartment in Rome. Through the window, she sees the figure she dreamt of. She searches the medicine cabinet and finds a bottle is prescribed to Julia Thorne. The Italian police barge in.
     
  8. Breaking Point (OAD 11/23/03)
    Now in Lindsey's custody, Sydney is imprisoned and tortured at Camp Williams, a secret NSC detention facility. She befriends Campbell, another prisoner.

    Lindsey relieves Dixon, who takes full responsibility for hiding Syd's secret. Lauren accuses Vaughan of aiding a fugitive, while he says Lindsey is funded by black money. Unconvinced, Lauren travels with Lindsey to Washington to observe Syd's interrogation.

    Vaughn goes to Jack, who tells him that Sloane will help them, making it look like The Covenant is trying to break out Syd. They put together a team of eight mercenaries. They will steal the Camp Williams blueprints from the FEMA building.

    Lindsey pressures Lauren, who's unaware of Syd's torture, to write a fair report of their treatment of Syd. He says he will threaten Syd with the memory-retrieval surgery in order to force her to decode a message found under her desk in Rome. He promises it will only be a threat.

    During her torture, Syd steals a paper clip. When Lauren suspects torture, Lindsey blackmails her by threatening to nail Vaughn for aiding Syd. Syd picks the lock with the clip, kills her torturer and breaks free. Lauren sees the guards beat Syd.

    Jack and Vaughn contact Brill, an old comrade, who joins them for a fee of $3 million. Jack takes Vaughn to a storage facility of guns and money.

    At FEMA, Sloane, in a van, knocks out their phone system and routes all calls to a fake number. Vaughn answers their request for a technician and Jack goes in. Meanwhile Sloane and Vaughn break into the building's sub-basement. Tapping into the phone lines, Sloane poses as a director and calls away Jack's guard. Vaughn pushes in a video snake and snaps images of the blueprints that Jack holds up to the camera.

    Jack is discovered and Sloane saves his life by taking a bullet for him. Sloane's allergic to morphine so Jack extracts the bullet without anesthesia. Jack wonders why Sloane saved his life. Sloane says he's a reformed man and that Jack and Syd are all he has left — his absolution, considering his crimes. Vaughn has Marshall access classified docs on NSC's computer network. Marshall finds that all files pertaining to Camp Williams have been removed. Lauren arrives, admits that Vaughn was right and offers her help.

    Lindsey tortures Campbell to force Syd to reveal the code. She capitulates, says they are coordinates but doesn't know to what. Campbell then reveals himself to be a fake. They knew Syd's profile, which reveals her major weakness to be empathy. Lindsey informs her that she will undergo the neuro-stimulation surgery in one hour.

    Jack, Vaughn and the team speed to the facility. Lauren, already there, opens the main gate. Jack enters, finds Syd's cell empty — she's on the operating table. The team finds her just in time and a gun battle ensues. Lauren shoots and kills Campbell. They take Syd to a chopper, where Sloane waits. Syd says she gave Lindsey the wrong coordinates.
     

  9. Conscious (OAD 11/30/03)
    Hiding out in a warehouse, the team devises a plan to frame The Covenant for Sydney's extraction: Lauren will tell Lindsey that she escaped The Covenant but they're still holding Sydney in return for the Rambaldi device. Sloane will confirm the story with Lindsey. Jack and Vaughn will say they were investigating Syd's trail. Lauren needs to look as if she was mistreated; Syd gladly punches her.

    Sloane also suggests Syd contact a Yale researcher named Dr. Edward Brazzel, who's invented a non-invasive technique for treating long-term amnesia. Jack and Syd later track her secret coordinates to a location near the San Andreas fault, where they find a severed hand bearing a Rambaldi tattoo. Meanwhile, Lindsey has the FBI arrest Dixon for impeding a federal investigation. Lindsey is suspicious of Lauren's story but agrees to trade for Syd.

    The group visits Brazzel's lab and find him and his assistant Kaya to be extremely eccentric. He believes dreams contain memories so, through a cocktail of dangerous drugs, he fools the brain into entering a lucid dream state. Once in this state, Syd must follow the thread of her last memory — and be wary of new, traumatic memories.

    Brazzel administers the drug and Syd enters the dream state. It's a surreal mix of past and present. She remembers being picked up by 3 hooded men after her fight with evil Francie. They inject her with something. She regresses to childhood — she cuts a birthday cake, which becomes a severed hand, and sees the face of a strange man. Back to the hooded men; she follows as they take her limp body to Room 47. Lauren guides her away, saying "You know better," then tries to strangle her with hanging plastic.
     

    In the real world, Brazzel revives Syd as she goes into cardiac arrest. When she awakes, she kisses Vaughn passionately, believing herself still in a dream.

    Syd says it was Lazarey's hand. Marshall's forensics prove the hand was attached to a living man only 4 months ago. Jack says the incriminating tape could have been a performance. Syd tells Vaughn that Lauren strangled her, but Brezzel says it was probably just a representational figure. Syd goes back under.

    Sloane meets Lindsey, who says he'll make the trade but wants Sydney assassinated in what appears to be a Covenant doublecross. Lindsey tells Sloane, who's wary of entrapment, that he knows what he's up to and gives Sloane an envelope containing some sort of proof.

    DNA from the Kremlin confirms the hand belonged to Lazarey, which means Syd didn't kill him and Lindsey has nothing on her.

    Syd is dreaming again. She's in a car, called a St. Aidan, with Dixon. She takes the box that contained the severed hand and walks into her apartment. Weiss and Marshall are there gambling. She enters the hanging plastic. Lauren tells her to leave. Syd chokes Lauren, who becomes a Sydney doppleganger. They struggle, the double says to trust Lazerey. Sydney shoots and kills the double and enters Room 47. "Oh my god," she says.
     

  10. Remnants (OAD 12/07/03)
    Sydney tells Jack about a dream — she's with Will in her old apartment and there's cereal box that says St. Aidan. Jack advises Syd to contact Will, who's in the witness protection program. Brezzel believes Syd's memory of the missing time has been removed and that the precision of the extraction indicates she may have been a willing participant.

    Syd visits Will in Wisconsin. Suspicious, he pulls a gun but she proves her identity, saying he's her oldest friend and that she loves him. Finally, he believes her and they hug. Sloane, under pressure from Lindsey, contracts Syd's assassin in Buenos Aires at a cost of $500K. Later, Jack socks Lindsey when he doubts his and Vaughn's sincerity and speaks brazenly about Syd. Now in custody, Jack advises Vaughn to push Syd away for her sake.

    Syd tells Will that Allison Doren is alive and working for The Covenant. He remembers that St. Aidan was the codename of an old Agency contact. He arranges to meet St. Aidan in Warsaw. Meanwhile, Sark attacks Brezzel at his lab and hooks him up to a morphine drip. Before he overdoses, Brezzel reveals that Syd was going to contact Will. St. Aidan meets Will — it's Lazarey. He refuses to talk about The Covenant. Syd has Will say that Julia Thorne sent him, that she trusts him and she's in danger. "Do they have it?" he asks. "Have they been to Gratz?"

    Sark appears and shoots Lazarey with a tranquilizer. A gun battle ensues. Syd and Will escape. Later, Will and Syd talk about the old days. She's lonely and, in a moment of vulnerability, they sleep together. Laying in bed, Syd realizes that she had "it," whatever that is, and assumes she would have hidden it in the Hotel Verlustzeit.

Sloane, under pressure from Lindsey, contracts Syd's assassin in Buenos Aires at a cost of $500K. Later, Jack socks Lindsey when he doubts his and Vaughn's sincerity and speaks brazenly about Syd. Now in custody, Jack advises Vaughn to push Syd away for her sake.

    Syd tells Will that Allison Doren is alive and working for The Covenant. He remembers that St. Aidan was the codename of an old Agency contact. He arranges to meet St. Aidan in Warsaw. Meanwhile, Sark attacks Brezzel at his lab and hooks him up to a morphine drip. Before he overdoses, Brezzel reveals that Syd was going to contact Will. St. Aidan meets Will — it's Lazarey. He refuses to talk about The Covenant. Syd has Will say that Julia Thorne sent him, that she trusts him and she's in danger. "Do they have it?" he asks. "Have they been to Gratz?"

    Sark appears and shoots Lazarey with a tranquilizer. A gun battle ensues. Syd and Will escape. Later, Will and Syd talk about the old days. She's lonely and, in a moment of vulnerability, they sleep together. Laying in bed, Syd realizes that she had "it," whatever that is, and assumes she would have hidden it in the Hotel Verlustzeit.
    In a torture chamber, Sark confronts his father, who initially doesn't recognize him. He says he staged his death to give Sark his inheritance. Sark says the inheritance now finances The Covenant. Lazarey says they are true evil and refuses to talk … Until Sark ignites a blowtorch.

    Will and Syd check into the Gratz hotel, posing as rock stars. Syd taps into the security system through the onscreen checkout and finds the location of a safe deposit box belonging to Julia Thorne. After disabling the security cameras, she breaks into the box, but Sark steals the object from under her nose. Allison attacks Will with a knife while Syd chases after Sark. In close combat, Will plunges the knife into Allison, killing her. Syd knocks out Sark and steals the object.

    Syd contacts Sloane, and prepares for the trade on the San Pedro docks. A team posing as The Covenant takes the Rambaldi device in exchange for Syd. The sniper fires — and kills Lindsey. Syd opens the crate in which the Rambaldi device is stored — it's filled with junk. Sloane says it was a setup engineered by Lindsey, who never intended to hand over the Rambaldi device. Syd doesn't believe him and promises he won't get away with it.

    At the CIA. Vaughn gives Syd the cold shoulder as Jack observes. Marshall examines the box — it contains human tissue and Milo Rambaldi's name is etched in the side. Will tells Syd that he's gotten no closure or satisfaction from killing Allison. He says he's going to stay in Wisconsin and promises to see her again.
     
  11. Full Disclosure (OAD 01/11/04)
    Agents from the Dept. of Special Research take possession of the Rambaldi Cube before Marshall can finish his own analysis of the tissue contained inside. Later, Syd is tranquilized and taken aboard a jet, where she sees Kendall, who reveals he's not FBI but Special Research. The Covenant has ambushed his team and now has the Cube. He says he knows what happened to Syd's missing two years but kept silent because she asked him to.

    Nine months after she was buried, he says, Syd called him from Rome, where she had escaped from The Covenant. She told him that she saw her funeral, paralyzed by a neurotoxin, from the back of a van. Her torturer, Oleg Madrczyk, had injected Syd's DNA into the teeth of a corpse, causing a false identification. She was taken to St. Petersburg, where she was called Julia Thorne and brainwashed. She killed a Covenant prisoner to prove her readiness.

    Syd is shocked at this tale, but Kendall says her Project Christmas training prevented her from being turned. She killed that man, who was doomed anyway, to protect herself and deceive The Covenant. She then contacted Kendall, who advised her to continue as Julia Thorne in order to gather info. Syd recalls the pain when she observes Vaughn with Lauren but stays away for safety's sake.

    Julia/Syd then partnered with Simon Walker to search for the Cube. She discovered Lazarey, an expert close to uncovering the artifact. Although The Covenant wanted Julia/Syd to kill Lazarey once he found the Cube, Kendall orders her to cut a deal with him and work together — so she fakes his death at her hands. Back in the jet, Kendall says he believes Syd is Rambaldi's Chosen One and that The Covenant wanted both her and the Cube to fulfill the prophecy.
    Julia and Lazarey find and retrieve the Cube in a cave in Namibia's Fish River Gorge. She has to amputate Lazarey's hand when a closing vault door crushes it. She never delivered the Cube to Kendall, however. He instead got a disc that showed Syd revealing that she was hiding the Cube and having her memory erased so it could never be found. She tells Kendall never to tell her what she's been through.

    In the jet, Kendall says Rambaldi's second coming is by way of a child. The Covenant will use the DNA in the Cube to fertilize the egg of the Chosen One. Syd looks at her scar — The Covenant extracted her eggs!

    Kendall says he respected her wishes, but four months after Hong Kong she went straight for the Cube. Why, he wonders. She remembers the package Sloane gave to her — the code and the key to the Rome apartment, which led her to Lazarey and the Cube. It was all a trick. Syd calls Marshall, who had secretly put a tracking device on the Cube. Meanwhile, Sark observes a series of test tube fertilizations.

    At the CIA, Dixon admits he knew the truth and was ordered not to say anything — a reversal of their SD-6 days. Syd, Dixon, Vaughn and Weiss parachute into Patagonia and storm to The Covenant's facility. Although Sark escapes, they find the fertilization equipment. Kendall wanted it brought back back for analysis but Dixon allows Syd to torch it all. Vaughn and Weiss rescue Lazarey.

    Later, Sark makes a phone call, ordering his father to be killed. As Lazarey is transported to a hospital, he asks Syd if she knows about the "passenger." He's then assassinated by a sniper. Lauren packs up her gun and flees the scene.
     
  12. Crossings (OAD 01/18/04)
    In a North Korean jail, Syd passionately kisses Vaughn before they're both led, in chains, to a firing line.

    The backstory: In Los Angeles, the CIA learns of a phantom offshore brokerage account. Encoded in the names of the stocks is a message — a top Covenant official, Leonid Lisenker, wants to defect. Syd and Vaughn will travel to N. Korea and, posing as auditors, spirit him away.

    Lauren asks Syd out to dinner during Vaughn's hockey night but Vaughn warns her not to socialize with Syd. Later, Lauren secretly meets with Mr. Zisman, a Covenant agent, to discuss Syd and Vaughn's assassination. Lauren hesitates but soon informs him that they'll board a jet at Dover Air Field. The Covenant poisons the pilots.

    Mid-flight, Syd gets angry at Vaughn's aloofness and says they can no longer work together. The jet veers out of control as the poison pilots take ill and die. Syd and Vaughn gain controls and take evasive maneuvers to avoid incoming missiles. The jet goes down. They survive the crash and flee the N. Korean military. They have 8 hours to meet the defector. As Syd and Vaughn commandeer a jeep, she admits to sleeping with Will but says she's moving on.

    Jack suspects the Covenant is responsible and Dixon, disobeying orders, tells the team to help in any way. Sloane calls to offer help but Jack denies him. He instead contacts Irina, who directs him to Syd's apartment. Once there, he meets Katya, Irina's sister, who confirms Syd's survival and offers her help on the condition he murder Sloane. She calls it a "preventative measure."
    In LA's Koreatown, Jack and Katya enter a restaurant and call on the owner, Mr. Cho, to repay a debt to Katya. When he declines, she stabs his hands with skewers and demands he contact Mr. Kwan.

    Syd and Vaughn arrive in Gai-Li and identify Lisenker. They see him with Sark, who's been informed of the defection through Lauren's treachery and is posing as a CIA agent. As a knife-wielding Syd confronts him, N. Korean troops appear. Sark flees as Syd and the others are caught.

    Jack enters Sloane's Zurich office, prepared to kill him. Meanwhile, Katya calls Sloane to tell him to back off Irina. She says he's not protected by his friends, even by Jack, — who's visible on Sloane's security system — and that his life is a favor from her. She then calls Jack and tells him to abort. Sloane tells Jack that he never forgot what it feels like to narrowly escape death.

    Syd and Vaughn are beaten in prison. Vaughn admits he pushed her away on purpose. She says they always find each other. They kiss passionately before they're led out to the firing squad. One soldier turns on all the others, it's Mr. Kwan. They then rescue Lisenker and escape.

    They're welcomed back to the CIA. Syd notices that Vaughn runs to Lauren. Jack tells Katya he knows what she did, that she destroyed Sloane's trust in him. He wonders to what advantage it served Irina. She says Irina's intentions will become clear to him some day. And then she kisses him ferociously.
     
  13. After Six (OAD 02/15/04)
    At the CIA, the team discusses info gleaned from Lisenker, the Covenant defector: He had hidden a microdisc containing Doleac Agenda, a "playbook" detailing plans for the six Covenant cells, in an impenetrable Chamonix chalet. Syd and Vaughn are to travel to Athens posing as diamond smugglers seeking the aid of Toni Cummings, the criminal expert who designed the chalet's security system. Under pressure from Jack, Syd has Dixon replace Vaughn with Weiss.

    Jack visits Sloane, who forgives him for the Katya incident. He says Emily's absence is a void that all his charity work can't fill. Jack tells him to stay focused and maintain his cover as a double agent. Syd, talking to CIA psychiatrist Dr. Arnett, says she can't move past Vaughn, whom she calls her "soul mate."

    Sark, leering at Lauren, confronts her and says he knows she killed his father. Knowing that she's Covenant too, and he proposes that they murder the six Covenant cell leaders, steal the keys to their respective headquarters, then meet with the head of Covenant operations in St. Petersburg. They'll then demand more power within the Covenant in return for not turning the keys in to the CIA.

    In Athens, Syd and Weiss lure Cummings to offer details of the chalet's lethal response security system. She gives them the schematics but says there is no way to pass the deadly obstacles. Marshall gets to work.

    Sloane shoots up, then calls Jack and tells him he needs a psychiatrist. When she visits him, he tries to manipulate her. She won't give in. Later, she says that she understands him. Sloane says he has a secret regarding Jack and Syd that wears on him. Dixon, reporting that Covenant officials are being killed, believes it's because the Covenant knows they're after the Doleac Agenda. Syd and Vaughn leave for Chamonix immediately. Jack accompanies them in order to execute Marshall's plan remotely.

    On the plane, Vaughn says he understands why Syd requested Weiss on the earlier mission. Syd stands firm and refuses to be "the other woman." Jack says the Agenda is encrypted in a microdoc hidden in the cork of a bottle of Chateau Margot 1953.

    At the chalet, Jack establishes a laser link to the security server, allowing Marshall to tap in. They have five minutes to get to the cellar. They inflate Marshall-manufactured inflatable Kevlar decoys, which trigger the machine guns to fire until they empty their clips. Carrie, Marhall's girlfriend, goes into labor and demands they get married before she has the baby. Weiss goes online and certifies himself as a minister and performs the ceremony while Marshall guides Syd and Vaughn through the chalet. They make it though an electrified tunnel and an acid kill zone, and find the bottle in the wine cellar as the alarm sounds. They barely make it out, as Jack kills two pursuing guards.

    Believing Lauren to be in LA, Sark travels to St. Petersburg to meet the head of Covenant operations — it's McKenas Cole, the former SD-6 rogue. Cole knows Sark's game; Lauren's double-crossed Sark. He knows the CIA has the Doleac Agenda, however, and believes Sark's treachery benefited them. As thanks, he gives Lauren and Sark leadership of the North American cell. He then tells Lauren to stop her husband's extracurricular activities. At the CIA, Lauren tells Syd to stay away from Vaughn.
     
  14. Blowback (OAD 03/07/04)
    Vaughn, unable to sleep, stares at his father's watch, which stopped the day he met Sydney. As Vaughn leaves, Lauren's phone rings. At the CIA, Dixon presents the team with a new mission: The Shining Sword, a Filipino terrorist organization, has acquired a next-generation bomb called a plasma charge, which they're shipping to Europe. The CIA has traced a Shining Sword transmission from a digital storage facility in Vancouver. Syd and Vaughn are to rent vault space at the facility and search for a detailed archive of the shipment. Someone within the Agency, Dixon adds, may be leaking info to the Covenant.

    Syd and Vaughn, posing as astronomers, arrive at the facility. They secretly download the shipping info and pinpoint location of plasma charge. Their uplink to Marshall, however, is sabotaged by a virus. Suddenly, they're attacked by a facility employee, who is mysteriously shot dead. Syd and Vaughn lose the murderer after a car chase through a parking garage. Back in LA, Marshall tells them he received 63% of the data; he'll need 12 hours to extrapolate the rest. Sydney recalls the previous day was the anniversary of Vaughn's father's death. Lauren calls, interrupting their conversation.

    In Zurich, Sloane apologizes to Barnett and asks her out to dinner. She agrees "for professional reasons only." She thinks his transformation from spy to humanitarian is remarkable and asks about the secret he's harboring. He's offended and explodes at her, so she walks out on him.

    Marshall's data reveals the plasma charge is on a Liberian freighter in Lisbon. Once on the boat, Syd and Vaughn, using a tracking device, are again fired upon.
    We go back to the opening— after Vaughn leaves, Lauren receives a call from Sark. He wants the plasma charge and tells her to get a lock on it, which she does via Dixon's team meeting. Syd tells Lauren that's she's not responsible for the problems in Lauren's marriage. Lauren then meets Sark at the Vancouver facility, where they plant the virus and force the employee to fire at Syd and Vaughn. When he misses, Lauren kills him and flees. After escaping, Lauren and Sark get shagadelic.

    Sloane apologizes to Barnett. He tells her his secret — he had a one-night affair with Irina Derevko. Jack and Emily never knew. Though he's never tried to prove it, he believes Syd is his daughter.

    Back to the gun battle on the boat — Syd finds the plasma charge. Vaughn stops Lauren, who's wearing a mask, and demands that she show herself. Before she does, Sark corners Syd and threatens to kill her unless Vaughn drops the gun. "If you love her, you'll drop the gun," Sark says. Vaughn drops it. Lauren punches him and runs. Syd breaks away from Sark and chases Lauren while Vaughn goes after Sark, who has the charge. He engages the timer and tosses it to Vaughn, who, with Marshall's aid, stops the countdown with seconds left.

    Later, Lauren meets Vaughn at a bar. Sark calls to goad her. She kisses Vaughn at Sark's behest. At the office late, Jack takes Syd out to dinner.
     
  15. Façade (OAD 03/14/04)
    Daniel Ryan, a freelance bomb maker whose bombs are impossible to defuse, destroys a bank in Belfast as a calling card to The Covenant. If he fails to cut a deal with The Covenant in 48 hours, he'll give notice to other terrorist groups with a bombing in the U.S. When the CIA learns that The Covenant is to meet him at the Black Stag Bar in Belfast, they send Weiss and Syd.

    Using Covenant defector Leonid Lisenker as a source of info, Syd poses as a Covenant agent. To improve her credibility with Ryan, she rescues him from an attempted CIA kidnapping led by Weiss. Ryan wakes in a CIA-built replica of the hotel room in which he does business with The Covenant. The ruse nearly fails, but Lisenker appears and vouches for Syd. Ryan accepts the deal on the condition that the details be handled by Sark, whom he's never met but knows is The Covenant's North American co-commander.

    Vaughn appears, posing as Sark. Ryan tells him the details will be given to him on a flight from Rome to Paris by an associate who will recognize him. He says the second bombing will be called off once the associate meets Sark. The CIA hurriedly issues a communiqué that compels Sark to board that flight, which Vaughn is also on. The associate never shows up, however, meaning that Ryan wanted Sark on that plane for an unknown reason.
    Sloane, sleeping with Judy Barnett, receives a call from a desperate Syd. He says Ryan's brother Christopher was killed by The Covenant. After some research, Syd remembers that The Covenant made her kill Christopher to test her Julia Thorne identity. Ryan plans to get revenge on The Covenant by blowing up Sark's flight.

    On the plane, Vaughn arrests and handcuffs Sark. After a call from Syd, he finds the bomb in the cargo hold. Marshall discovers that the detonator is based on barometric pressure — the bomb will explode if the plane descends below 18 thousand feet. If Vaughn detaches the motion sensor, Marshall says, they may be able to fool the bomb into thinking it's in high altitude.

    Syd, Weiss and Lisenker reveal themselves to Ryan, hoping the revelation convinces Ryan to stop the bomb. Syd appeals to Ryan's compassion, saying she was tortured by The Covenant and made to assume the Julia Thorne identity.

    Vaughn uncuffs Sark, and together they try to disable the motion sensor. Ryan agrees to help and dials in a deactivation sequence. It's only a ploy — he had heard a rumor that Julia Thorne had killed his brother — he activates the bomb, as well as the one Marshall had been studying in his office!

    With the clock ticking, Jack chokes Ryan until he passes out, then revives him. If he doesn't give them the code, Jack says, he won't be revived next time. Ryan gives it up with one second to spare. The danger over, Sark attacks Vaughn, who knocks him out and turns him over to the French authorities. When Vaughn returns, a tearful Syd embraces him
     
  16. Taken (OAD 03/21/04)
    Senator Reed, Lauren's father, arrives to oversee Sark's interrogation. He tells Jack that they must learn the identity of Sark's partner in The Covenant. Lauren advises against torturing Sark.

    The plane carrying Sark to Dover Air Force Base from France lands in the desert, 60 miles short of the runway. Syd and Weiss board the plane, only to find the pilots and guards dead and Sark missing. The dead appear to be frozen. Meanwhile, Dixon learns that Sark has kidnapped his two children. Sark demands the release of five international prisoners in 48 hours — an impossible task. A shaken Dixon demands the team find the mole.

    Marshall, analyzing the flight voice recording, learns that Sark made a phone call and referred to someone as "love" before he bailed out over Arizona. The CIA traces Sark to Nogales. Syd, Vaughn, Weiss and Dixon enter the compound but the kids aren't there — it's a trap. They barely make it out before the place blows.

    Marshall searches the FAA database and discovers Sark's flight was accessed from Switzerland via Dr. Barnett's IP address. Jack immediately arrests Sloane and jails him. Syd stops Dixon from beating him. Dixon returns home to find his boy safe but The Covenant now demands the release of ten prisoners. Dixon appoints Jack as team leader and privately tells Syd that The Covenant's demands are false. They're actually demanding a Rambaldi object, from Project Black Hole, located in the Nevada Desert. Syd agrees to help him retrieve it.
    Syd sneaks into the facility via a steam shaft while Dixon enters with his clearance. Dixon gains access to the security system and opens a grate for Syd, just before she's steamed. Dixon directs Syd to the correct room and she outfoxes a mechanized guard to retrieve the object — a cube. Engraved in it is the name Irina.

    Jack learns that The Covenant is close to locating a key to operate the cube. The contents, he tells Syd, will threaten her life. Nonetheless, Syd decides to exchange the cube for Dixon's daughter. Senator Reed, learning that Dixon stole the cube, deploys a team to bring him into custody. Lauren appeals to Vaughn to help Dixon.

    With Federal choppers searching for Dixon, he, Jack and Syd meet Sark and Dixon's daughter. Vaughn has Marshall misdirect the chopper's GPS systems. Dixon gives Sark the cube. Sark fits the girl with a collar armed with a deadly toxin as insurance that he escapes. Syd volunteers to wear the collar. Jack disarms the collar as Sark flees.

    A furious Barnett, visiting Sloane in jail, believes she's been used. Proclaiming his innocence, Sloane asks that she keep mum about his secret. Jack overhears Lauren call Vaughn "love."
     
  17. The Frame (OAD 03/28/04)
    Vaughn and Syd travel to Mexico City searching for the key to open the Rambaldi box. Via Vaughn's contact Kishell, they learn that the box contains a bio-weapon. In 1941, they learn, two Soviet archeologists found the "map," an etched crystal revealing the location of the key. The men turned on each other, however, and died in the Karoo desert. Kishell has images of Covenant kingpin Kazari Bomani at the site — with the crystal. In the background is a truck belonging to Omnifam, Sloane's humanitarian organization. Kishell says The Covenant refers to the map as The Passenger.

    Later, Sloane explains to Syd that the CIA forced him to partner with Bomani to stay close to The Covenant. If his pardon is revoked, she says, the death penalty will be reinstated. He says all Omnifam trucks can be tracked with GPS. He offers to give her the tracking codes in return for creature comforts.

    At a restaurant, Vaughn tells Lauren that he wants to separate. Lauren says it's about Sydney and storms off — straight to Sark, who tells her to kill her father, which would compel Vaughn to return to her out of compassion. Meanwhile, a suspicious Jack prints out Lauren's phone records. Visiting Senator George Reed, Jack meets his wife Olivia. He then reveals to the senator the paper trail leading to his Lauren. Reed is incensed and denies his daughter's involvement.

    Marshal tracks the Omnifam trucks to the Russian consulate in Gaborone, where the CIA believes Sark and Bomani have the map. Syd and Vaughn enter a function at the consulate, posing as a Russian couture designer and a waiter, respectively. They engage in a firefight with Sark and Bomani and escape with the crystal. On the return flight, Vaughn tells Syd that he's separating from Lauren.

    Marshal is unable to interpret the crystal's kaleidoscopic data. Syd gives Sloane The Iliad in return for his help. He says that there are four disks that fit into the box's carved slots. He tells them to look under water. With this information, Marshal is able to use the data to pinpoint a rock formation off the coast of Okinawa.
    Lauren realizes her computer has been accessed by Jack (she has an intrusion detection program). She calls Sark, who again advises her to kill her father and then frame Jack. Lauren visits her father, who's now convinced of Lauren's guilt. He suggests that he can help her get out of it and they could start over to patch their relationship. Olivia walks in, takes the gun from Lauren, and shoots him! She says, "Sark said you might back out."

    During the investigation, Olivia tells Jack that, before killing himself, George had grown distraught about asking Lauren to do things that he later regretted. He mentioned the Covenant, she says.

    In the Sea of Japan, Syd and Vaughn scuba to an underwater cave and locate the keys. Bomani arrives and says The Passenger is Irina's legacy. Syd fights Bomani while Vaughn battles Bomani's mercenaries. Syd beats Bomani, but he destroys their scuba equipment and flees with the keys. They use a tank with a broken valve to act as a propulsion device to rocket them to the surface. On the plane back, Syd says Vaughn's problems are unfortunate, but she's hopeful. He asks her out to coffee when they get home.

    Dixon refuses Lauren's resignation, telling her that she was acting at her father's instruction with what she thought was approved government protocol. Jack tells Dixon there's no reason to believe it wasn't suicide, but Dixon says they may still have reason to hold Sloane. Vaughn and Syd arrive and learn of Senator Reed's death. To Syd's dismay, Vaughn embraces Lauren. Later that night, Vaughn calls Syd to tell her he's back with Lauren.

    Sloane demands to be released after he learns that Senator Reed was Covenant. But Dixon says the senator's records indicate he consulted with Sloane about Rambaldi and that Sloane handed over certain artifacts to him. The pardon has been revoked, Dixon says, and he'll be executed in two weeks.
     
  18. Unveiled (OAD 04/11/04)
    Dixon asks Sloane how Il Dire (The Telling) will help The Covenant obtain The Passenger. Sloane asks to speak to Jack, even though Dixon's made it clear that Sloane's execution won't be stayed.

    Dixon explains to the team that a computer worm, originating in Berlin, has targeted hospitals, laboratories and universities. They believe it's a Covenant attack, a precursor to the Rambaldi bio-weapon. Syd and Vaughn travel to a Berlin Goth club to find the culprit, a hacker known as Cypher, and learn how to stop the worm.

    In Florence, Sark and Bomani use the keys to open the Rambaldi box, revealing the beating di Regno heart. The box is an elaborate writing machine that scratches a message onto a scroll of parchment. Later Bomani compares the codes gathered by the worm to the parchment. Sark learns from Lauren that the CIA has discovered Cypher. Bomani expresses doubts about Lauren's work.

    Lauren tells Vaughn that, while he's in Berlin, she'll go to England to meet her mother and scatter her father's ashes in Dover. In Berlin, Syd locates Cypher with a PDA-sniffing pair of sunglasses given to her by Marshall. Before he talks, however, he's shot. Syd thinks she sees Lauren in the distance. Cypher's last act is to give Vaughn a small drive containing the files with the worm's source code.

    Lauren tells Sark that she has to corrupt the files before the CIA makes a copy -- before Bomani knows that she failed. Sloane tells Jack that two years ago Senator Reed recruited him to work for The Trust, an organization within the U.S. government interested in Rambaldi, in return for a pardon. He wants Jack to prove that this group exists.

    At a CIA safe house in Berlin, Syd tells Vaughn that she saw Lauren. Vaughn reacts angrily. Lauren shows up, looking to cry on Vaughn's shoulder. He notices she's wearing an antique ring. She claims its an heirloom. Syd calls Mrs. Reed to check out Lauren's alibi. Her story holds. As Vaughn uploads Cypher's data to Marshall, Lauren touches the ring to the drive. Later, Marshall tells them that flash drive's memory was wiped. He suggests it was purposely exposed to an electromagnetic pulse. However, he's able to partially reconstruct the source code and determines that its real purpose was to gather information for The Covenant.
    Bomani realizes the CIA cut their data feed. Syd tells Jack that she seriously suspects Lauren. Jack pays Vaughn a visit, tells him that Irina would sometimes camouflage the truth in a kiss. An outraged Vaughn says Lauren is no Irina and he is not Jack.

    Marshall finds the worm was searching for the genetic code for one woman. There are ten possibilities. Lauren downloads the data, then tells Vaughn she has errands to run. He follows her to a mall, watches her receive a phone call - Sark warns her off the drop; he wants to see her in person. Vaughn has Weiss run a tap on Lauren's phone and he overhears her speaking intensely. Later, Lauren tells Vaughn that she got a call from her mother (which explains the phone call to Vaughn).

    Dixon says the ten women are actually aliases for one woman. Records reveal this woman was always treated by one doctor -- Robert Viadro in Milan. Syd and Vaughn go to Milan. Lauren is already there. Viadro knocks the amethyst from Lauren's ring but she subdues him in a Panic Room and tortures him until he reveals The Passenger's location. Syd and Vaughn arrive, fight off guards belonging to The Order of Rambaldi, and find Viadro. Vaughn also finds Lauren's amethyst. When Viadro sees Syd, he says, "You're the one from the prophecy. You will not hurt her." He tries to kill Syd. Vaughn shoots him dead.

    Lauren gives Bomani a computer disc. He's about to kill her when Sark shoots him dead. Jack's contact Diego tells him the front for The Trust is Project Centrigrade. Dixon tells Jack that Barnett's notes reveal that Sloane had an affair with Irina. Jack tells Sloane that he couldn't verify existence of The Trust. Sloane says that both Jack and Syd will be affected if The Covenant finds The Passenger.

    Jack tells Syd that he thinks The Passenger is Irina, because Il Dire's message said "peace," the etymology of which is a derivation of Irina. Vaughn asks Lauren what she did while he was gone. She just gives him a kiss. Vaughn checks her belongings while she's in the bath. Under the false bottom of a trunk, he finds a Goth wig, a passport and a gun
     
  19. Hourglass (OAD 04/18/04)
    In a Nepal monastery, Sark, looking for info on The Passenger, threatens the Rambaldi monk known as Conrad. The wise man kicks the crap out of him. Olivia Reed appears and tranquilizes Conrad. Sark then takes a manuscript regarding The Passenger, called The Restoration.

    During an online chat with Irina, Jack asks her about The Passenger. The account is suddenly terminated. Vaughn admits to Syd and Jack that Lauren is the mole. Jack says he should play along. So when Lauren asks Vaughn to come to counseling, he agrees.

    Dixon receives intel that The Covenant has kidnapped Conrad. In the Thar desert, Syd and Vaughn intercept the convoy on horseback. Syd jumps into the truck, beats a guard and grabs Conrad while Vaughn trails them. As they climb out toward Vaughn, Sark shoots Conrad. With his dying breath he says to Sydney, "The Passenger is your sister."

    In LA , Jack reveals to Syd that Sloane had an affair with Irina. Syd confronts Sloane at his prison cell. He says he never knew he had a daughter with Irina until he reached the Nepal monastery. The Di Regno heart and Il Dire gave him the woman's DNA and the word "peace," which translates to Irina in Greek. Using Omnifam, he gained access to DNA databases but never found her. Now, he wants to protect her from The Covenant. He asks Syd to convince Jack not to hide evidence which would exonerate him. Jack later says he's hiding nothing.

    Only the CIA's Project Black Hole has the codekey that can read The Restoration. Jack sets a trap - He leaks to Lauren that Marshall has The Restoration and will begin decoding it with the codekey. She copies his thumb print, using it to access the Image Processing lab to duplicate the codekey, which, in fact, is a fake.
    Syd and Vaughn are shocked to find Lauren passing the fake to her mother Olivia. They overhear Olivia say The Restoration is at home in Richmond. During a counseling session, Dr. Barnett slyly suggests that Vaughn take a trip with Lauren to Richmond. Once there, Vaughn hides a sensor that Marshall uses to find a hidden safe. Syd phones him and directs him to it while Lauren and Olivia are outside. He scans and transmits the documents with a watch. Vaughn finishes just before Lauren enters. Syd disconnects her comm as they fool around.

    The documents reveal a Rambaldi artifact known as the Hourglass, which was auctioned to Masa Raidon, a yakuza keeping the arkwork in a building in Little Tokyo. The manuscript says The Hourglass will reveal the location of The Passenger only to her father. Sloane will be executed in 6 hours. The Justice Dept won't stay the execution.

    Syd bluffs Jack into agreeing to turn over his info on The Trust and exonerating Sloane. Jack then talks with Sloane, bringing champagne to his cell to celebrate the knowledge of a daughter. Jack accuses him of trying to take Syd away from him. He refuses to help Sloane and threatens The Passenger.

    Syd treads delicately in the Yakuza stronghold but when Marshall tells her Dixon is at the execution, she kicks in to high gear. As Sloane enters his execution chamber, Syd, double guns blazing, mows down the guards and grabs The Hourglass. Sloane slowly dies as he receives a combination of lethal injections.

    Syd later turns her back on her father. Lauren, informing Olivia of Sloane's death, admits that Vaughn played her. Jack, meanwhile, revives Sloane. He had given him an antidote in the bottle of champagne. Jack orchestrated, he tells Sloane, it because he needs him.
     
  20. Blood Ties (OAD 04/25/04)
    Jack tells Syd that he saved Sloane because he had learned that DOJ Director Marlon Bell was part of The Trust and wanted Sloane dead. Syd tells Sloane that she didn't grieve for him.

    Sloane reveals that he found a Rambaldi text that contained a formula for an elixir that would allow The Passenger to channel a message from Rambaldi. Sloane had sampled the elixir, which had no effect. Sloane explains that if The Covenant finds her, it will expose her to a massive dose of the elixir, thus killing her. He swears he just wants to protect his child. When Syd asks how to find her, he smashes The Hourglass, revealing a glowing green ball.

    Dixon has Weiss tail Lauren and advises Vaughn to continue as her devoted husband in order to garner info. Lauren, however, soon loses Weiss. Ex agent Thomas Brill contacts Vaughn. He says Vaughn's father was a Rambaldi follower who freed The Passenger, then a little girl, from KGB custody and hid her. He died protecting her.

    On a plane to Washington, D.C., Syd holds the green ball, a battery for a Rambaldi artifact that can locate The Passenger. The Trust has a cold storage vault in the Smithsonian secured by a five-key retinal system corresponding to the five member of The Trust -- all government officials. In D.C., Sloane makes himself known to Bell, who calls a meeting with The Trust that Sloane crashes.

    Sark kidnaps and tortures Vaughn, trying to get The Passenger's location. Lauren appears and, apparently disturbed by Vaughn's condition, helps him escape.

    While Sloane gathers the retinal ID's from the Trust via a hidden scanner, Syd enters Smithsonian posing as a dinosaur expert researching a paper. She charms the curator into letting her gain access to a restricted area, where she finds the vault. Jack sends the scans to Syd, who uses them to open the vault. She grabs the artifact.
    Later, Sloane drops the green ball into the artifact, which etches a brain wave pattern on parchment. They use a DOD satellite network capable of remote encephalography to locate The Passenger. She's in a labor camp in Chechnya, under the alias of Talia Kozlov. Syd infiltrates the Chechen camp and finds her sister in a catatonic state and strapped to a bed.

    Vaughn flags a trucker and uses his cell phone to call Dixon. Vaughn is rightfully suspicious. The truck crashes after the trucker attacks him. Sark and Lauren grab Vaughn again but Marshall witnesses it on a surveillance tape. They begin to administer the dreaded Inferno Protocol serum on Vaughn when Sark receives a mysterious phone call revealing the location. Lauren increases the dosage in order to kill Vaughn and they leave. Weiss, using Marhsall's info, finds Vaughn barely alive.

    The woman wakes and she and Syd battle their way out. She tells Syd that her name is Nadia and she's with SIDE, Argentine Intelligence. Syd reveals that they're sisters. They meet up with Jack and Sloane and retreat to a safe house. Nadia recognizes Sloane, who tells her that he changed because he didn't want to meet his daughter and have her despise him.

    Sark and Lauren break into the safe house. During the gun battle, Sloane and Nadia disappear. Jack and Syd realized that Sloane tipped The Covenant to give himself the opportunity to escape with Nadia. They can't relocate her by her brainwaves.

    Dixon tells Syd that Vaughn shows evidence of psychological conditioning, thanks to Lauren. Syd visits Vaughn in the hospital. He says she must let The Passenger go and reveals the reason that Irina killed his father. He relays a prophecy: The Passenger and The Chosen One will battle and neither will survive. Syd is unmoved.

    Sloane injects Nadia, strapped to a table, with the elixir. She convulses.
     
  21. Legacy (OAD 05/02/04)
    Sloane takes the notes that an entranced Nadia has written and pins them to a board, where they form some kind of diagram. With Sloane's guard down, Nadia stabs him with a hypodermic and destroys the Rambaldi elixir, but he subdues her. He calls a contact to deliver more bottles in exchange for $5 million. The contact then calls Sark.

    The CIA intercepts the call between Sloane and the contact and learn that the elixir is stored in an inactive Russian bunker called Novgorod 21 that was once the center of Soviet Rambaldi research. Syd suggests they plant a tracking device on one of the vials.

    Syd and Vaughn arrive at the bunker only to find it ransacked and the elixir missing. Vaughn begins to retrieve and upload any available data to Marshall. They find video files revealing Nadia Santos as a young girl, recording messages while under a trance. Russian guards, led by Katya Derevko, surprise them. She turns on the guards, however, and tranquilizes them. She reveals herself to be Syd's aunt then orders them to wear the guard uniforms. They run barrel through a checkpoint and escape.

    In St. Petersburg, Katya says Lauren and Sark took the elixir. She reveals that the young Nadia was taken from that lab by Vaughn's father before she could complete the message. Katya, working with SRV (Russian Intelligence), says Irina gave birth to Nadia in a Russian prison after she left Jack. Katya has been helping Irina to locate Nadia ever since and is dismayed to hear that Sloane has her.

    Sark and Lauren deliver the elixir to Sloane in exchange for a partnership. Sloane reluctantly accepts, and administers a does to Nadia to prove that she's The Passenger. Marshall, meanwhile, explains to Syd that the fluid contains potentially toxic proteins that trigger a muscular memory, forcing Nadia to relay the message. The memory is genetically stored only in descendants of Rambaldi. They view an old videotape wherein Dr. Jong Lee, aka Suit and Glasses, injects Nadia with the elixir. Dixon reveals that Lee was in charge of conducting Russia's Passenger experiments. He's now in a Cuban bio-weapons facility.
    Jack warns Vaughn not to let his thirst for revenge against Lauren endanger Sydney. He gives Vaughn a key to his well-armed security facility -implicitly suggesting he kill Lauren.

    While Jack and Katya track Sloane's bank withdrawals, he rebuffs her advances. He notices that Sloane made a large payment to a Dayton Electrical, a company that did electronics work in Chamonix. Jack makes the connection and visits Toni Cummings in prison. When Jack agrees to reduce her sentence, Cummings tells Jack that she drew up specs for a system for Sloane but doesn't know where he built it.

    In Cienfuegos, Cuba, Syd and Vaughn find Dr. Lee. He says Nadia drew coordinates that would lead to Rambaldi. Vaughn tortures him by dripping acid on his leg. Sydney is shocked and appalled.

    Marshall works with Cummings to get a delivery nexus for parts to Sloane's system. Cummings unsuccessfully tries to convince Marhsall to work for her. Marshall finds that Sloane's sytem is in Japan. She says she needs to travel there to determine which of the seven security variables she'd given Sloane is being used.

    In Sloane's Kyoto estate, Sark urges him to increase the dosage to Nadia, who's building up a tolerance, even though it might kill her. He refuses. Sark kills Sloane's guards and Lauren ups the dose. Just then, Cummings hacks the security system and the CIA storms the compound. Sloane escapes while Syd tends to Nadia. Vaughn chases fruitlessly after Lauren and Sark, leaving Syd to dispatch Sloane's guards herself. Nadia shoots a guard about to kill Syd. They recover the drawings and texts and escape.

    Dixon says Vaughn allowed Sloane to escape. Syd covers for Vaughn, despite her anger. He says she got Nadia and that's what counts. Syd says they can't work things out until he deals with his anger. Jack visits Katya and plants a kiss on her. Vaughn goes to Jack's storage facility and chooses a sniper rifle from the array of weapons.
     
  22. Resurrection (OAD 05/23/04)
    Sydney strategically places cell phones throughout the office. She patches into the CIA computer and downloads the Rambaldi equation. Then she contacts Sark - Sydney is actually Lauren in disguise! She shoots Marshall when he questions her. As she bolts, the cell phones explode. Vaughn follows "Syd," but she knocks him out, then escapes by stealing a car.

    The real Syd is interrogated by Hank Foster, Counterintelligence Threat Analysis. Believing she was somehow involved in the break-in, he reassigns her to a desk job pending further investigation.

    Vaughn tells Jack that he's prepared to exact revenge on Lauren. Jack tells Dixon to have Vaughn question Sark, in order to increase the psychological fear. Vaughn beats Sark bloody during the investigation. Sark gives Lauren up.

    Syd calls Vaughn, and intuits that Vaughn knows Lauren's location. She asks Jack why the Sark interrogation is classified. He dodges the question, saying that Vaughn should kill Lauren to gain closure. He says that he regrets letting Irina go.

    Vaughn spies on Lauren decrypting the equation in a warehouse. He photographs the longitude and latitude, then surprises her and administers a beating. About to disfigure her with hydrochloric acid, Vaughn is stabbed from behind and collapses.
    Sloane sneaks into a CIA safe house and begs Nadia to tell him the location of The Sphere of Life - the vessel in which Rambaldi's consciousness is stored. She's dubious. Before he leaves, he tells her how to find him.

    Syd and Jack wait for Vaughn in the hospital. Now Syd vows to kill Lauren, whether Jack, who is alarmed at her transition, helps her or not.

    Lauren appears in the jail cell next to Sark. She forgives him for giving her up. He tells her that the Rambaldi info is backed up on an offsite server and gives her the password. It's not Lauren, but Syd - who removes her mask! When she determines that the equation leads to Palermo, Sicily, she leaves immediately. Vaughn tells Weiss that Katya Derevko stabbed him and that Syd is walking into a trap. Vaughn uses Weiss to create a diversion to escape the hospital.

    Syd finds Katya in the Palermo site. She says she's tracking The Covenant and that she knows Lauren is present. Katya tries to shoot Syd, but Syd had secretly removed the cartridge from Katya's gun. Syd then shoots Katya. Lauren arrives but Syd misses her shot and Lauren runs.

    Nadia escapes the CIA safe house to meet Sloane, who tells her that the Sphere may be compromised because The Covenant has solved the equation. She says that she purposely altered the equation - The Covenant is looking in the wrong place. She and Sloane venture off together to find the Sphere.

    Syd and Lauren fight. Lauren says that Syd still doesn't know the truth about her life. Lauren is about to finish Syd off when Vaughn shoots Lauren dead. Before she dies, Lauren tells Syd that the truth is in box 1062 in the Bank of Wittenberg. Syd and Vaughn kiss.

    In Wittenberg, Syd opens the safe deposit box and finds top secret documents. She cries as she peruses files documenting her life, each one bearing Jack Bristow's signature. Jack enters and says she was never supposed to have found these documents.

Season Four

  1. Authorized Personnel Only (Part 1)
    Sydney, on a train, in lingerie, flirts with a man to get into his … briefcase. He unlocks it, revealing a canister containing an unstable isotope. She knocks him out and takes it, runs into the corridor. A thug follows and is about to push her off the train...

    Shanghai 72 hours earlier … Sydney, in a naughty schoolgirl outfit, escapes with a contact into a club's bathroom. It's a mission gone bad, a fellow agent is killed, and in order to escape she makes her contact dress like a goth.

    In LA, Syd is berated for violating protocol by Director Chase and stripped of her classified clearance. Sydney then quits the CIA. In Washington, Vaughn and Weiss talk about his meltdown after discovering Lauren's treachery. Vaughn says he's quitting.

    Sydney walks down a subway, opens a secret doorway and enters an office. Director Chase is there and welcomes her. She explains Langley approved this black ops division only months ago. Dixon, Jack, Vaughn are all there -- a team handpicked by Sloane. Chase privately tells Syd that they need Sloane's contacts -- and the team is a safeguard against Sloane's potential treachery.
    Sloane explains that their covert unit is like the CIA's own SD-6, called APO -- Authorized Personnel Only. Their first mission targets a Russian scientist named Yuri Kamarov, who wants to sell an isotope to an unknown buyer on a Belorussian train. Vaughn will act as the buyer while Syd grabs the isotope. She's openly disdainful toward Sloane.

    On the train, Syd barges in to Kamarov's room claiming that it's her room. Vaughn poses as Kamarov and meets the buyer, who works for a Mr. Vadik, while Sydney occupies the real scientist. The buyer recognizes Vaughn and puts a thug on him as he leaves. Vaughn signals Syd, who swipes the isotope. Vaughn beats the thug and races to save Syd. He throws her assailant off the train. They make love. After, he asks Syd what happened at Wittenburg. Syd flashes back -- she's reading a top-secret document as Jack enters.
     
  2. Authorized Personnel Only (Part 2)
    Sloane plans for Syd to talk to Nadia about Vadik, whom she once tracked. Sloane says that Nadia quit the intelligence business and returned to Argentina after they found a Rambaldi artifact and handed it over to the US government. In Argentina, Nadia won't return but tells Syd that Vadik's right hand is Tomazaki.

    At home, Syd tells Vaughn about Wittenburg -- she learned that day that her father had killed her mother, Irina Derevko.

    Tomazaki has disappeared. They learn that five years ago he unsuccessfully tried to steal the Shintaro sword from a London museum. Sloane suggests they steal the sword as bait. At Dixon's suggestion, they enlist Marshall. In the museum, Syd triggers the alarms but manages to steal the sword and, with Jack's help, escapes the police.

    Later Jack tells Sloane that he didn't tell Syd everything in Wittenburg.

    Dixon arranges to sell the Shintaro sword to Tomazaki in Rio de Janiero. Tomazaki's jailed thug tells Jack that Vadik is Tomazaki. At the agreed meeting, Tomazaki kidnaps Syd. Vaughn asks Nadia for help. Tomazaki asks a perplexed Syd how she found out about the hit. He tortures her. He says he was supposed to assassinate her but the day before the hit, his client was killed.

    Nadia steal a key card from a Tomazaki associate and saves Sydney from drowning during the water torture. Tomazaki knocks her out. He attacks Syd with the sword but she runs him through. Before he dies, he says that Irina Derevko hired him to kill her.

    Sloane announces that Nadia has joined APO. Syd tells Jack that Tomazaki had the contract. He doesn't know why Irina wanted Syd dead. Vaughn comforts a shaken Syd.

    Nadia and Syd travel to Moscow, where Syd had Irina interred. Syd tells Nadia she has no idea who killed her. Nadia swears that she'll kill whoever murdered their mother.
     
  3. The Awful Truth
    In Nassau, The Bahamas, Syd and Marshall arrive incognito at a bank under the pretense of creating an account while Vaughn and Dixon create a diversion. When the manager leaves momentarily, Syd and Marshall access an account.

    Back in LA, Weiss and Nadia - who's now living with Syd, hit it off at a party Syd hosts. Jack crashes the party, says her Bahamas mission paid off, they have info on Bishop, owner of the account, and Valta. He wants to know if she told Nadia that he killed Irinia. Syd hasn't but thinks it best if she does.

    Sloane says Valta, a computer that will revolutionize info gathering from satellite networks, was stolen from the NSA headquarters 10 days prior by Martin Bishop, who will be deliver it to a German terrorist group. Bishop, a British ex-pat living in Spain, awaits final payment before delivering Valta. The team must recover or destroy the computer.

    They determine that Valta's whereabouts are stored on a powerful server on Bishop's estate in Andalusia, Spain, and they can only hack into it from the inside. Once in Spain, the team sets a trap for Bishop using Syd as bait - she portrays a mysterious woman caught in an overturned car. Bishop rescues her and invites him to her home. He tells her not to wander the grounds.

    Jack administers a psych test to Nadia. He tells Sloane that he's learned enough to deal with the problem.
    With Vaughn monitoring the situation, Syd sneaks away and finds the server in the basement. She determines that Valta is located at Malaga's Alameda Yards in container C0717. Bishop's suspicion is raised when he runs into Syd as she returns to her room. Sloane sends a team to Malaga to find Valta and tells Jack that Syd may be in trouble.

    At Alameda Yards, a CIA team destroys Valta, but Weiss is captured. Bishop is informed of the raid and learns that someone accessed his server. An alarmed Syd signals for help, and Vaughn and Dixon go in only to find the house empty. Marshall tracks Bishop by his cell phone signal.

    Jack tells Nadia he doesn't blame her for Irina's infidelity and hands her classified documents before they are dispatched to Spain, where they liaison with Vaughn. Bishop holds both Weiss and Syd captive. Bishop hopes to off them up to the terrorist group as a replacement for the computer. Syd breaks free of the ropes and beats the guard -- Weiss now realizes she's black ops. They go after bishop. Vaughn meets up with Weiss. Syd trails Bishop, jumps on top of his car and shoots him through the roof. He slams the breaks and she tumbles off. He's about to shoot her when he is killed by Nadia, who a pumps a few extra rounds into him. She says he was the one who killed Irina, their mother - Jack lied to her!

    Later, Jack admits to Syd that he adjusted details in the documents to manipulate Nadia and give her closure. He says a satisfying lie can do more good than the awful truth
     
  4. Ice
    With Vaughn and Dixon covering, Syd tries to buy a bio-weapon called Ice 5 from an American at a foreign bazaar. When thugs disrupt the deal, Syd bolts with the man. As they're running, his leg snaps off. He's then shot - and literally explodes.

    Marshall later determines that the biological agent, which the man had swallowed, actually "freeze-dried" him, crystallized him from the inside. He worked as a relief worker in Montenegro hospital run by Fenton Keene, who secretly developed Ice 5. Sloane wants the team to obtain a viable sample of Ice 5.

    At Syd's home, Nadia finds a photo of Irina holding a baby. Nadia asks Sloane who the baby in the picture is. He dodges the question.

    Syd visits the hospital as a representative of Omnifam and does the grunt work, while Weiss and Nadia put together a list of potential buyers. A patient comes in showing symptoms of Ice 5 infection but the nurse, Kyra MacLane, says he was in a car accident and won't let Syd help treat him.

    Vaughn, disguised as a priest with a black eye, flirts with MacLane and convinces her to make confession. Fenton appears, tells Vaughn that he's her brother and asks to see the man in the car accident. Meanwhile, Syd swipes MacLane's card key and passes it to Dixon, who makes a copy and gives it to Syd.

    Syd searches the lab and finds 14 tanks of Ice 5. To her horror, she spies Fenton testing it on human subjects. Weiss reports that they found a buyer in Damascus. They find MacLane is really Fenton's sister, and that they're both former IRA. Vaughn feels she can be turned and approaches her during confession.

    When they meet, MacLane says her brother has done awful things. With Syd listening in, Vaughn tells MacLane that he's haunted by thoughts of his former wife, whom he killed after she betrayed him. MacLane realizes Vaughn is government. He tells her that he can protect her from her brother should she turn on him.

    MacLane takes Vaughn to the lab, where Fenton clobbers him. He's forces MacLane to inject Ice 5 into Vaughn's eye. Syd enters and rescues Vaughn. During the fight, Fenton stabs his sister by accident. She dies in Vaughn's arms, but forgives him before passing.

    Jack asks Nadia for the photograph. He said Irina told her she was holding her niece. The next day, he recalls, he proposed. He says he chooses to believe it's true, but says that everyone needs to find our own sense of closure.

    On the return flight, Syd, sensing a disconnect, tells Vaughn he can talk to her whenever he wants.
     
  5. Welcome To Liberty Village
    A Russian-speaking man steals a device from an armored truck. He goes home to a suburban neighborhood and greets his loving wife in English.

    At APO, Sloane says the stolen object was an EMP, an electromagnetic pulse weapon. Marshall says it can destroy any electronic equipment in a 10 mile radius and has a repeatable core. The thief, Yuri Karylko, has ties to October Contingent. In related news, German authorities have arrested a Chechen couple, the Tabakovs, who said the October Contingent had made overtures to them. Syd and Vaughn are to pose as the Tabakovs to infiltrate the Contingent, identify their mission and retrieve the EMP. Marshall gives Syd a wristwatch that can send their GPS coordinates and is capable of short burst transmissions. Sloane, meanwhile, tells Jack to contact Alexi Vaselyvich.

    In Moscow, Karylko gives Syd and Vaughn new identities -- they are to be known as David and Karen Parker - and takes them to Liberty Village. Marshall tracks their journey to Training Sector 56B, a former Russian military base that now resembles a suburban American neighborhood. Syd and Vaughn arrive at the neighborhood. They are taken to their new home and introduced to the neighborhood.

    Karylko, going under the name Tom, says Syd and Vaughn will be tested to see if they can portray Americans convincingly. Marshals picks up Syd's transmission and identifies the "neighbors" as assorted terrorists. Sloane wonders why the Contingent is dealing with terrorists and why they're in a government training ground.

    Ironically, Tom tells Syd and Vaughn that they seem a little cold. He gives them a gun. While Syd goes jogging, Vaughn practices assembling the gun. Syd runs into Tom, who tells her that the neighborhood is heavily guarded.

    Jack meets Alexi and asks if the Russians still run the old base. Alexi bargains with Jack, expecting something in return for extracting Syd.
    Tom gives Syd and Vaughn wedding rings so they look more like a couple. He takes them to a car dealership, their mission is to buy a convertible. The dealer sees the ring, asks how he popped the question. Vaughn spins a tale that moves Syd. The dealer says another couple is also interested in the car. The winning couple gets to move on in the program, he says. The losing couple dies. He gives them a gun to assemble, both couples race to assemble it.

    Jack opens a book from Irina's collection of 1st editions. The NSA had cracked the orders the KGB encoded in the books. He tells Marshall that the NSA missed something and puts him to work on it.

    The couples shoot it out in the car dealership. In the melee, Vaughn loses the gun. Syd picks it up and kills the woman. She then jumps in the car and runs down the man. Later, Syd notices that the watch is broken. She and Vaughn kiss in the shower.

    Marshall finds the code in the ink of a period within an ellipsis. After magnifying it, he sees that it contains a protocol related to one of Irinas operatives, codename Sentinel. Jack says Sentinel is a dead end, a deceased agent. Jack gives the book to Alexi, who says he hasn't heard from Irina a long time. He also says he has an aircraft waiting to extract Syd and Vaughn.

    Tom prepares to send Syd and Vaughn Chicago, where they are to gain access to the servers of Pierce Financial. Tom's plan is for a "redistribution of wealth" after an attack on the U.S.

    Marshall receives word that the Germans have moved the Tabakovs to a maximum security prison - and assumes the Russians have been informed also.

    Tom shows Syd how to use the EMP. He then receives a call from his wife. Knowing her cover is blown, Syd knocks him over the head with a vase and they fight. In another room, Vaughn battles another thug. Syd and Vaughn escape outside where a helicopter has them pinned. Syd triggers the EMP and the chopper falls from the sky.

    Afterward, Sloane thanks Syd and Vaughn. He says Russian authorities deny an American training ground ever existed in their borders but off the record they've expressed gratitude for APO's assistance in taking down the October Contingent. Privately, Jack says his suspicions regarding Sentinel are accurate, and the Russians are searching for Irina Derevko. Sloane says they'll have to move up their timetable. Syd and Vaughn canoodle on the plane home.
     
  6. Nocturne
    A woman teaching English to foreign students believes she's being watched. Convinced she can't escape, she draws a gun and kills herself.

    Syd and Vaughn, playing hockey when they get the call, report to Sloane. He explains that when Nancy Cahill, an undercover narcotics agent, shot herself, her last words were "Tell them it's funny." Cahill's husband Jason, also an agent, has gone off the grid. Syd and Jack are to search the Cahill's Amsterdam apartment for clues.

    In the apartment, Syd unlocks a crawlspace door and follows a passage to a room plastered with disturbing drawings. She's suddenly attacked and bitten in the throat by a feral Jason. Jack shoots him dead.

    As Syd undergoes a battery of tests, the doctor says the Cahills came in contact with a drug that caused an acute melatonin imbalance, which incited their acts of extreme violence. Syd's diagnostics indicate that she's fine.

    Sloane says Langley wants to find the drug, who manufactured it and what it's used for. Marshall traces the calls Nancy made and begins reconstructing erased files on her laptop. Weiss says Jason was trying to determine what he was infected with, even after Nancy locked him in the closet.

    Syd can't sleep and begins hallucinating. Her temperature reads 111.

    Jason's files indicate he had a meeting scheduled in Bucharest with "The Count," a drug supplier. Syd mission is to pose as a Cahill associate and meet The Count. Dixon tells Sloane it's a mistake to send Syd out so soon. Sloane harshly reprimands him.
    In Bucharest, Syd has a recurring hallucination of a spider. Marshall calls Jack to say the drug's incubation period is a few days, like a virus, and permanently alters brain chemistry. Jack tells Vaughn that they should have her in sight at all times. At the meeting, Syd imagines Vaughn kissing someone. They take The Count into custody, and admits he recently delivered samples of a drug called "Nocturne" to Jason. Once the delusions begin, there's no stopping it. Syd, increasingly off-kilter, imagines Sloanee threatening her. Syd chokes The Count, who offers that the drug came from Prague and was an old sample meant to be destroyed.

    Nadia finds a group called Grappig, which means "Tell them it's funny" - an affiliation of biochemical scientists in Prague led by Dr. Letuza. Nancy had found out where it came from but was too far gone. Vaughn says Letuza may have developed a remedy if he knew he made a bad batch. In Prague, Vaughn searhes for Letuza's files. Syd grows fearful that Jack will kill her. She asks to be tied up and Jack obliges. She imagines Jack comparing her to Irina. Syd head butts him, takes his knife and cuts herself loose.

    Vaughn finds vials of antidote and returns to see Syd crying over an immobile Jack. She says she killed him, but it's a trap. She has a gun, forces him to his knees. She says their relationship is a cruel joke at her expense and that she's scared she will betray him again. She fires but the gun has no bullets. They fight. She beats him with a pipe. Jack wakes and subdues Syd with a sleeper hold. Jack had taken the bullets out! Vaughn administers the antidote.

    In LA, Sloane says Interpol has raided Letuza's office and eradicated the Nocturne threat. Sloane admits to Dixon that sending Sydney was a tactical error. An angry and humiliated Dixon says he never saw the nature of SD-6 because his only failure was that of imagination -- he never imagined a person as thoroughly toxic as Sloane could exist. When Sloane's true motive reveals itself, Dixon promises to be there.

    Syd and Vaughn kiss in her hospital room. She sees a spider on her bed. Vaughn brushes it away and says spiders are good luck.
     
  7. Détente
    In Irkutsk, Vaughn learns from a contact that Russia has produced a breakthrough explosive called Black Thorine. The contact suspects his superior stole it and sold it, and gives Vaughn the man's bank account number. Soldiers arrive and shoot the man, Vaughn escapes with Syd's assistance.

    Syd arrives home to find Sloane visiting Nadia. Despite Nadia's objection, Syd kicks him out, saying he can't be trusted. She only took the APO job to watch him. Nadia realizes Syd hasn't reconciled the past.

    At APO, Sloane says that money was deposited into the account by Boris Tambor, an oil magnate who moonlights as an arms dealer. He's currently in Monte Carlo. Jack says he sits at a high stakes poker table every night at 9. Their mission is to get into his suite, find out where he keeps the black Thorine and how he plans to move it.

    Syd confides to Dixon that she may not be able to work with Sloane. Dixon says he dreams of his dead wife Diane every night; she tells him to do the right thing. That's how he makes peace with Sloane -- he doesn't ignore the past, but he makes the right decision today.

    As they shoot targets at a firing range, Syd tells Nadia that she needed to know her mother and so understands Nadia's desire to know Sloane.

    In Monte Carlo, Syd inserts a micro camera into the suite and gets a visual on Tambor, who's watching a soccer match - not going to the gaming table. Nadia and Syd notice perfume, a purse, magazines. They realize he's got a girlfriend. Deducing that the woman is bored, pissed off because she's being ignored and sitting in the bar, they see their opening.
    Dressed up to party, Nadia and Syd identify the girlfriend through her perfume. They befriend the woman; she takes them up to the room and past security. Syd clones his PDA hard drive while Nadia chats up Tambor.

    In LA, Sloane is angry at them for taking risks. Syd gets indignant at what he deems "unacceptable." Everywhere she looks, she says, she's reminded of Francie and Danny. Marshall has broken the hard drive's encryption and finds out that Tambor will sell the vial on his yacht, Argento, which is sailing in Turkish waters in the Black Sea. It's stored in a safe within a safe in a cabin below deck. Marshall gives Syd a device that will allow her to read the safe's combination through his clothes.

    Jack lobbies for Sloane to allow Syd and Nadia to work together again. They swim to the yacht and sneak on board. Syd uses the combination reader while Tambor makes the deal. Sloane recognizes the buyer as Leo Orissa, the head of a Russian crime syndicate. Nadia opens the safe - revealing eight canisters of Black Thorine.

    Orissa ambushes Tambor, whose girlfriend turns on him. Tambor is killed as Syd and Nadia escape to the water. Sloane tells Syd he has to trust him and advises her to go back on board. Confronting Orissa, Syd says she works for Arvin Sloane, which sends fear into the man. Syd catalogues Sloane's depravity. Orissa offers up the location of the lab. Meanwhile, Nadia disposes of Orissa's thugs. The lab, Orissa says, is in the Ukraine. Tambor's girlfriend shoots Orissa and fights Syd. With an assist from Nadia, Syd kills her.

    Nadia tells syd she's always been alone. Now she's glad to work on a team. Sloane assumes Syd wants a transfer. Syd says she will never forgive him. "I'll see you tomorrow," she says.
     
  8. Echoes
    Before the team meets, Nadia gushes about Weiss to Syd while Weiss moons about Nadia to Vaughn. Sloane recuses himself from the upcoming mission because it involves an operative that he is not authorized to engage. He puts Jack in charge and leaves the briefing. Jack says the target is Syd's old nemesis Anna Espinoza, a former K-Directorate Agent and Rambaldi follower, presumed to be dead. Intel indicates that Espinoza is to receive something from an associate, Milos Sabine, in Brussels. While reviewing the files, Nadia gets lightheaded and walks out. Syd, Dixon and Marshall are to observe the meet and bring her in if the opportunity exists.

    At lunch with Nadia, Syd talks about past encounters with Anna. Nadia says she saw something awful when she was connected to Rambaldi last year -- She had a vision that she and Syd were aiming guns at each other. She pulled the trigger and shot Syd, she says, who seemed to expect it.

    Syd takes a call - it's from Anna, who's actually sitting behind Nadia. She kidnaps Nadia and demands that Syd pose as her in Brussels for the meeting with Sabine.

    In Brussel, Sabine says he wants to get his money's worth before he gives her the item. He tells Syd to kill Willem Karg, who's in a hotel bar, photograph the body as evidence and bring back his right index finger. If she's not back in 40 minutes, she won't get the package.

    Syd poses as a prostitute and lures Karg to go up to his room - where Vaughn and Dixon wait. They cut off his finger to save his life. She presents it to Sabine; he gives her the "last remaining sample."

    Anna has her thug Mr. Turner brand Nadia with the Rambaldi symbol.

    Marshall identifies the sample as the Dante Compound, a rare putty that when mixed with V/X gas and other nerve agents, will mutates them. Marshall believes Anna works for the Cadmus Revolutionary Front, an offshoot of the Covenant. They've been trying to acquire the compound for a year to make a chemical bomb. He suggests they talk to Sark.

    Sydney doesn't think they should follow through on a plan to give Anna a replica of the Dante Compound because she may kill Nadia. Sloane says Anna won't kill Nadia - he says it's not her destiny. Syd realizes this is about Rambaldi. Jack agrees that Syd should meet with Anna.
    They meet in a Beverly Hills boutique. Syd gives her the compound. Anna gives syd a remote car key and tells her to go to the 4th floor of a parking structure across the street. Anna threatens Syd, who starts a knock-down, drag-out brawl that ends in a virtual stalemate. Realizing that they're getting nowhere, they make the exchange. Syd finds Nadia locked in a car trunk.

    Vaughn visits Sark in the federal pen. Sark asks if he killed Lauren because of espionage or infidelity. Vaughn hits him and asks why the CRF has made repeated attempts to contact him. When Sark goes silent, Vaughn has him shipped to Alder Penitentiary, where he is to spend all his days in dark solitary confinement.

    Syd returns with Nadia. The surgeon says they can fix the brand. Nadia relates Anna says that she and Syd will be torn apart. Syd explains that according to their mother, the outermarkings of the Rambaldi symbol are her two daughters, the center is the object over which they'll do grave battle with each other. Only one of the daughters will survive. Syd says some of these predictions have come true, but that she doesn't believe in it. The people who do, she says, are dangerous.

    Jack injects Sark with a tracking device (and explosive) while he sleeps in prison. As Sark is transferred, the vehicle is attacked. - it's a set-up. And a man helps Sark escape.

    Syd hears chatter about a meeting between the CRF and an administrator of a Russian chemical facility named Vorich. Syd thinks Anna may be there. Jack tells her to take Nadia for surveillance only. If Vorich is there, he may have a sample of V/X. Sloane is afraid that if Syd and Nadia go on the mission together and Anna has her way, only one will return. Marshall tracks Sark to Johannesburg.

    In Johannesburg, the team raids what they think is CRF headquarters, only to find Sark in an empty room guzzling champagne. He agrees to locate CRF leadership in return for something.

    In Estonia, Nadia and Syd find Vorich, who's quickly killed by Anna. Nadia battles Mr. Turner as Syd chases Anna. The dude falls on his knife, Nadia twists it until he reveals in his dying breath why the CRF is assembling the bomb. Syd think she's cornered Anna, but it turns out to be Nadia. Anna then shoots Nadia in the back. She falls as the life ebbs from her.
     
  9. A Man of His Word
    Sloane and Syd watch over the injured Nadia, who remains stable in a medically-induced coma. Syd tells him that Anna has the bomb.

    Sark is brought before Sloane, who asks him to retrieve that bomb. According to Sark, Ushek Sanko, the leader of the CRF, will take possession of the bomb from Anna Espinosa. Sark agrees to retrieve the bomb on the condition that he be allowed to view Lauren Reed's body - and that Vaughn opens the coffin.

    Lauren's body is stored in a CIA mortuary lest her death become public knowledge. Vaughn opens the lid. Sark, studying her bullet wounds, deduces that Vaughn killed her.

    Sloane tells Syd that, according to Rambaldi, Nadia can't die by Anna's hand. Anna sneaks into the hospital to assassinate Nadia, but Sloane secretly had her moved to a different room. Syd gives chase but Anna escapes through a window, using a firehose to break her fall.

    Nadia is moved to the CIA sickbay. Sloane tells Jack to eliminate Anna. Marshall observing the security camera tape of Karg's confession to Nadia, sees Anna observing from the shadows - which explains why she wants Nadia dead.

    Vaughn and Syd take Sark to meet Sanko at a club in Venice. Syd impersonates Lauren in order to accompany Sark. She kisses Sark (biting him on the lip) to titillate Sanko. Before Sanko can reveal any info, Anna shoots and kills him. Syd handcuffs Sark to a railing while she and Vaughn look for Anna, who frees Sark and extracts the tracking device/explosive from his neck.

    Over dinner, Anna tells Sark that she killed Sanko because he wouldn't pay her enough for the bomb. She wants to contact a buyer, Michele Gignon, an arms dealer with whom Sark has a relationship, and suggests they form a partnership.

    Jack makes the risky decision to inject Nadia with a counter-agent, waking her from the coma. He gleans the necessary info from her and passes it to Syd. The doctor recognizes the drug in Nadia's system and tells Sloane.

    When Sark and Anna meet Michele in Venice, Syd and Vaughn make their move. Vaughn recovers the bomb. Sark turns on Anna, and leaves her to Syd. They have another hand-to-hand showdown. This time, Syd slaps the cuffs on her, pistol-whipping her for good measure. Sark, however, escapes.

    An angry Sloane confronts Jack about forcibly waking Nadia from the coma. Jack quotes Sloane, saying his orders were "to do what it takes." He also refers to the prophecy, saying it wasn't Nadia's time. Nonetheless, Sloane says that Jack should have told him that he put his daughter at risk. Jack says Sloane puts Syd at risk every day. Their relationship appears severely damaged.
     
  10. The Index
    Sydney, Weiss and Nadia discuss Nadia's upcoming birthday. Nadia doesn't want to celebrate; she doesn't even know when her real birthday is.

    At the team briefing, Sloane tells them about the Blackwell Index, an encrypted disc once owned by the CIA that contains incriminating evidence against many government officials and corporate heads. The CIA was never able to crack it, and now the disc has been stolen. The team is to steal a Decoder disc housed in an evidence room in a Paris police precinct. Vaughn is passed over for the mission - he's heading to Arizona to visit his comatose uncle.

    Dixon approaches Syd, saying that he refuses to follow Sloane blindly and now double-checks all information - he's even installed a wiretap in his office, and though the line is encrypted, he's traced a call Sloane made to Miles Deveraux, a former Alliance agent. Dixon then goes to Director Chase, who says he needs more proof that Sloane is reforming The Alliance. Dixon asks for Syd's help in decoding the conversations.

    In the Arizona hospital, a nurse named Rosemary tells Vaughn that his uncle frequently spoke about Vaughn's father, Bill. She gives Vaughn an envelope from the uncle, meant for Vaughn's father. Later, Vaughn opens a locker in a Mesa bus station and finds a diary with entries dating to 1982. Bill Vaughn died in 1979.

    Syd shows Dixon a mini-disc burner, created by Marshall, which will produce a corrupted copy of the Decoder Disc. They agree to give Sloane the phony copy.

    In Paris, Sydney, who is dressed as an American punk, vandalizes Weiss's vehicle in order to get arrested. Dixon arrives as Sydney's lawyer and quickly shoots the guard with a tranquilizer.

    Nadia remotely guides Syd to the evidence room of the police station. She finds the Decoder while Nadia scrambles the security camera. Sydney makes the corrupted copy and flees from the police. She races to the roof and leaps on to a helicopter piloted by Weiss.
    At APO, Syd convinces Sloane to hold a dinner party for Nadia's birthday. At the party, Syd gets a phone call from Dixon. She retreats to Sloane's office and transmits Sloane's decoded conversations with Devereux. The conversation revealed Sloane's contact with Deveraux, and an implied reformation of SD-6. As Syd is about to leave, she sees Nadia standing before her. Nadia accuses Syd of using her but Syd enlightens her. Dixon, armed with the decoded conversations, convinces Director Chase that Sloane must be taken down.

    In Brussels, Sydney, Nadia, Dixon and Chase observe Sloane as he enters an abandoned building. Inside, Deveraux presents the Blackwell Index, which is to be cracked using the decoder that Sloane now has, to a group of men.

    Sydney, Dixon and Director Chase run into the building, leaving Nadia to wait for them in the car. As the three burst through the door, they find Sloane alone in a deserted room, with a laptop. They discover that Sloane is actually conducting surveillance as Jack meets with Alliance members. Syd realizes that Jack has the false Decoder just as Devereaux begins to doubt Jack. Nadia speeds to the meeting and arrives in time to takes out the Alliance members, saving Jack's life.

    Miles away, Vaughn tries to speak with his comatose uncle. "Is he still alive?" Vaughn asks. No answer. Vaughn asks the head nurse if he can speak to Rosemary. The nurse says nobody by that name works there.

    Sloane, in his home office, inserts the Decoder Disc into his laptop, revealing the Blackwell Index. He then calls Jack and tells him it has everything they need -- and more.
     
  11. The Road Home
    Disguised as a French woman, Sydney acquires a microchip from a contact named Thomas Connelly in a Paris restaurant. Before the deal goes down, an assassin shoots Thomas. Vaughn, watching from the shadows, prevents him from killing Syd. As Vaughn and Syd corner him, he slits his own throat with a knife.

    In the APO office, Sloane tells Jack and Sydney that the information downloaded from the microchip reveals that a Biometric Targeting Device is being developed at a secure facility in Austria. If attached to a weapons system, this device could facilitate the targeting of an individual based only on a DNA sample or a biometric scan. It is the next generation's sniper.

    Sloane tells Sydney that the assassin worked for Sasha Korjev, a vicious arms dealer involved in developing the new targeting weapon. Sydney's mission is to retrieve the Biometric device in Salzburg, Austria. Sloane gives Dixon the task of locating Korjev but Jack volunteers to do it himself.

    Weiss suggests that Vaughn is mistaken in believing that his father, Bill Vaughn, is still alive. Vaughn swears it was his father's handwriting in the diary. Weiss hands Vaughn a paper with the name Frank Murdoch, an ex-Special Forces man in San Diego whose shop is mentioned in Bill's journal.

    Jack later admits to Sloane that the CIA wants Korjev assassinated and he can get closer to him than Dixon can. Jack adds Korjev should've been eliminated years ago, when he "had the chance."

    In an Austrian club, Sydney befriends Sam, an American busboy, and uses his I.D. to get into the basement. She finds a status report revealing that the Biometric device has been moved and is scheduled to leave the country in the morning. The report also states that the device had been installed on a weapon.
    A guard shoots at Sydney. She decks him and overhears on his walkie-talkie that the weapon is stored at the Delongpre shipping yard - and that the guards are now after Sam. After Marshall confirms that Sam is a civilian, Syd escapes with him. She leaves him with her Austrian contact so he can be put in a protection program.

    In San Diego, Vaughn visits Frank, who shows him a photo taken with Bill in 1982. Frank says that Bill was ruthless enough to shoot him in the back, then smoke a cigarette over his bloody body before walking away. Vaughn later lies to Weiss, saying he never found Frank.

    Sydney's contact in Salzburg arrives with a stranger to pick up Sam, and she senses something's not quite right. Realizing his betrayal, she pounds them senseless and reluctantly explains her mission to Sam. She asks for his help to get to the shipping yard.

    In Angola, Jack meets Korjev, who wistfully remembers Jack as a mentor. Later, Korjev speaks of Jack's betrayal. Jack says he was the one betrayed and garrots him.

    At the shipping yard, Syd discovers that the weapon has been attached to an assault chopper. She tells Sam to wait in the van. Syd defeats the guards in combat and attempts to retrieve the weaponized mini-copter -- but the system activates and locks on to her. As it fires, she runs through a maze of narrow aisles and crates.

    While Sam waits, he's wounded by a Korjev henchman. Syd tackles the gunman but the chopper locks on to her again. Sydney quickly uses the gunman as a human shield. The chopper, hovering closer, senses the corpse and, believing its mission is accomplished, settles on the landing pad.

    Sydney arrives in the APO office in time to see Jack preparing to leave. As Jack mentions that he is planning to have dinner before heading home, Sydney asks if she could join him and they leave together.
     
  12. The Orphan
    It's 1992. A man sneaks into a Buenos Aires orphanage in the middle of the night and tries to kidnap one of the girls. A young Nadia resists him and escapes.

    Vaughn shares his father's journal with Sydney. He asks her for access to the Operational Archives. Later, Vaughn decodes an address in Lisbon that may help reveal the mystery of his father's life.

    At APO, Sloane says that the Belorussian Institute of Science had developed a next gen optical component called the Amplifying Glass, which can boost a laser pulse. It can enable a CD player's laser to shoot a plane from the sky or slice a tank in half. A Jakarta faction has employed Cesar Martinez, an Argentine resident, to acquire it for them. Nadia knows him - they were once partners in crime.

    Nadia reports that Martinez is a freelancer, and he earned his reputation with the execution of former Argentine intelligence officer, Roberto Fox. Their mission is to outfox Martinez and obtain the Amplifying Glass at a party held in the Minsk Institute of Science. As the team leaves the room, Nadia admits to Sydney that she knows Martinez.

    A blonde Sydney arrives at an elegant party in the Institute of Science. She charms an architect, whose Blackberry holds the building's blue prints and project files. After scanning his PDA with Marshall's help, Syd waits for Nadia, who has stolen a key from one of the scientists.

    Later, Nadia spots Cesar Martinez. Nadia again flashes back to her teenage years. She's crying in the corner of a jail cell. Roberto Fox recruits her to work in espionage for the government. Nadia consults the headmistress of the orphanage, who encourages her to take the job. At the party, gunmen open fire as Martinez follows Sydney's path.
    In the lab, Syd cracks the safe and retrieves the Amplifying Glass. When Martinez and his thugs enter, Syd surrenders the Glass. Martinez asks Sydney who she works for. Nadia arrives and says, "She works with me." He spares their lives.

    Back at APO, Sloane reprimands Nadia for not sharing her past regarding Martinez. Nadia insists she can get the Glass back from Martinez. She doesn't tell them that she actually worked with Martinez under Roberto's tutelage.

    In Buenos Aires, Nadia sits at an outdoor restaurant while Sydney and Weiss observe from a van. Martinez arrives and agrees to sell the Glass to Nadia on the condition that she accompany him back to his office without backup. Nadia agrees despite Syd's reservations.

    Martinez asks Nadia if she still thinks about Roberto Fox. Nadia recalls finding her dying partner, who says that Roberto Fox is a criminal who had them steal government intelligence. Nadia thought she'd been working for the Argentine government.

    Nadia admits to killing Fox and says she'd do it again. Martinez levels a gun at her. She hits him and turns the table, now aiming it at him. Sydney arrives with Weiss. Nadia tells them that the Amplifying Glass is in the safe and Weiss takes Martinez away. Sydney and Nadia embrace.

    In Lisbon, Vaughn rings the door of the address mentioned in his father's journal. The door opens to reveal Nadia's headmistress at the orphanage! She says the only time she met Vaughn's father was when he came to her, covered in blood with a baby in his arms -- the baby was Nadia. Pressed for further details the headmistress says she heard his father mention one particular word during a phone conversation -- "Nightingale."
     
  13. Tuesday
    At an upscale nightclub in Havana, Cuba, Sydney invites a man to dance. It's her informant, and he tells her that the Third Faction is planning a large-scale attack on a civilian target. He also tells Sydney where a hard drive containing more information could be found, which Dixon soon retrieves. They're being watched, however.

    As Syd travels to the airport, Vaughn, over the phone, promises her a slow dance. Suddenly, attackers shoot Syd's driver and the car crashes.

    Dixon arrives at APO with the hard drive. Since Marshall is late, another agent is tasked with the decryption. When the drive is plugged in it sprays a toxin in the office, causing Dixon to go into a seizure. He's given an antidote and the office is locked down.

    As Marshall arrives in the parking lot, he phones Sloane to tell him that the firewall networks are still secure. Sloane asks Marshall to stay on the line as they contact Sydney.

    The ringing phone wakes Syd. To her horror, she realizes she's been buried alive, the dead informant beside her. Jack advises her to stay calm -- but that help won't be coming for the next 36 hours while the office is locked down. Marshall volunteers to go to Cuba and track Sydney's cell phone with a Radio Frequency locator.

    While Dixon recuperates, Sloane tells the rest of the team that the Third Faction has enough toxin to infect an entire city. Despite their predicament, they must still discover the target city and prevent the Cyclosarin bomb from detonating.

    Marshall arrives in Havana and creates his makeshift RF Locator. Sydney takes a photo of the dead informant and sends it through her phone to APO. Using the picture, the team links the dead man to Ulrich Kottor, a significant figure in the Third Faction, and the man who kidnapped Syd.
    Syd's phone dies as Marshall arrives at the cemetery. Marshall realizes there are too many fresh graves for him to search. He asks Vaughn to direct a satellite over his position and change the view to thermal, figuring it will pick up Syd's body heat.

    Marshall digs frantically, finally opening the coffin and finding Sydney unconscious. He performs CPR. After a few tense moments, she opens her eyes. An exhausted Marshall drops to the ground.

    In the office, Sloane reports that they have acquired information about Ulrich. Since an attack is imminent, Sydney needs to get to Ulrich, find his hard drive and upload the contents to APO so they can stop the detonation. Sydney responds by saying that Ulrich knows her from Havana, and that they need to send someone else in: Marshall.

    Syd advises Marshall on the spy game. Marshall, assuming an intimidating pose as Jack Bristow, walks inside Ulrich's private room and commands his attention. He tells Ulrich that one of his men is betraying him. As his "cigarette case" scans Ulrich's laptop, Vaughn reports from APO that they still can't access the data, and that Marshall must go to the basement with Ulrich in order to force him to shut down the network firewall. As Marshall tries to subtly assemble the gun he brought, he accidentally shoots and kills Ulrich. He calls Syd for help.

    From the APO office, Jack instructs Marshall to dig out one of Ulrich's eyes. Sydney arrives and, using the eye, they bypass the retinal scan in the basement security system. Marshall then starts downloading from the hard drive and transmits intel to APO while Syd covers him. Later, Sloane reports that the Ministry of Security confirmed the seizure of the Cyclosarin bomb in downtown Hong Kong.

    Sydney drops Marshall off at his house and he invites her in for dinner. A grateful Sydney refuses, saying that she needs to go the train station. At the station, Vaughn arrives. They slow dance in the middle of the train station, blissfully unaware of the bustling world around them
     
  14. Nightingale
    Vaughn wakes up from a nightmare. Troubled, he tells Sydney that they should stop pursuing his father's past. Syd insists that they continue.

    In a Siberian nuclear facility, two men lock an unconscious prisoner into a test chamber, while a scientist observes behind glass. When the prisoner wakes up, he realizes that he's the subject of a gruesome experiment. His flesh melts and he dies screaming.

    Jack agrees to Syd's request for clearance on files relating to Vaughn's father. Starting with one word - Nightingale - from Bill Vaughn's journal, Syd discovers its connection to Dr. Josef Vlachko. She also finds that he's currently working with Hans Dietrich, a money launderer involved in weapons sales who funneled over a million euros to an account labeled Nightingale. Syd presses on with the search.

    A wary Sloane asks Jack how much Sydney and Vaughn know about Project Nightingale. Jack suggests that they tacitly let the pair continue the search.

    In a rogue operation, Syd and Vaughn go to Dietrich's beer hall in Munich. Dressed as a beer maid, Sydney charms Dietrich. Then they go back to his private office where she beats him and rips out the hard drive from his computer. As guards arrive, Syd and Vaughn fight their way out.

    Back in Los Angeles, Vaughn secretly meets with a mysterious man named Roberts, who knows about their "trip" to Munich. Roberts says he'll give Vaughn info about his father in exchange for the transformer coil from Project Nightingale. Vaughn agrees, though he doesn't yet know what Nightingale is. Before he leaves, Roberts gives him his contact information and the name "Philip Burke" as a lead.

    Jack invites Sydney out for dinner to learn more about their acquired intel. Sydney says that Vlachko is running Project Nightingale in an abandoned nuclear plant and using humans as test subjects for experiments. Jack tries to convince Sydney to bring this intel to APO.
    Sloane tells Jack that due to Vlachko's ties with Elena Derevko, he needs to send a strike team to Siberia. Jack says they should wait for Sydney to willfully bring this to APO. Once she does, Jack will join the mission so he can interrogate Vlachko without Syd and Vaughn's knowledge. Sloane advises Jack to eliminate Vlachko because he can alert Elena about their agenda-or worse, talk to Sydney.

    Vaughn tells Sydney about Philip Burke: he was killed the same day that Bill Vaughn was supposedly killed, and his dental records are identical to Bill Vaughn's. Vaughn also says that he met with Roberts, who wants the transformer coil. Syd suggests they bring this operation to APO, then acquire the coil through a rogue countermission. After they report to APO, Jack says that he'll join them in the retrieval of the transformer coil.

    After infiltrating the Siberian nuclear facility, Jack shuts down security while Vaughn and Sydney run toward the test chamber. Sydney enters the chamber to retrieve the coil inside the nuclear reactor's containment shield. A guard arrives and shoots at Vaughn, destroying the control panel in the process. Syd is trapped inside as the nuclear reactor starts counting down. After Vaughn's failed attempts to stop the reactor, Marshall says another way to stop this is through the removal of fuel rods from the core.

    Meanwhile, Jack finds and interrogates Vlachko. Upon hearing that Sydney's life is in danger, Jack shoots Vlahcko and heads toward the nuclear core to remove the fuel rods. Marshall advises Jack against this as he tries his best to bypass the system.

    Suddenly, the nuclear reactor shuts down. Syd walks out the chamber and hands the coil to Vaughn. After they kiss, Vaughn punches Sydney and runs away with the coil as Syd watches him go. Sydney then goes to Jack and tells him that Vaughn took the coil from her.

    Jack and Sloane discuss Sydney and Vaughn's deceit. Later, Marshall realizes that Jack shut down the reactor himself. Jack tells Marshall that his daughter's life depended on it and demands that his actions remain a secret.
     
  15. Pandora
    Dixon is shot by a masked gunman. The shooter approaches and takes off his mask, revealing … Vaughn.

    Two days earlier, Vaughn meets a man named Roberts in a Paris cafe. Vaughn tells him that Roberts' employer will only get the transformer coil if they give more information about Bill Vaughn first. Roberts calls his employer and has him speak to Vaughn. The voice says that since Vaughn didn't follow their agreement, he must first complete an assignment. As instructed, Vaughn reaches under their table and opens an envelope containing surveillance pictures of Bill Vaughn, who, the voice confirms, is very much alive.

    At a federal prison, Nadia visits Katya Derevko, who fondly recalls her childhood with Irina. Nadia refuses to talk about Syd, although Katya desperately wants to see her.

    Concerned about Jack's exposure to radiation in the last mission, Marshall secretly uses the oil from Jack's fingerprints to create a sample that he sends to forensics for analysis. Later, Marshall learns that the results show a large-scale genetic mutation. He begs Jack to see a doctor.

    Vaughn meets with a group of freelancers hired for the assignment. Roberts announces that they must steal a valuable item from an armored van - but first, they need a cold laser stored in a private hospital at Bordeaux. Vaughn and a team member infiltrate the hospital, first disguised as a couple needing medical attention, then as a doctor and a nurse. They successfully steal the laser.

    After Nadia confesses to Sydney that she's been visiting Katya to learn more about Irina, Syd warns Nadia and reveals that Irina had hired an assassin to kill her. An angry Syd storms off to see Katya in the hospital.

    Syd tells Katya to stay away from Nadia. Katya says that she would never harm Syd, nor would Irina. Before her death, Katya says, Irina believed that someone was setting her up to make it appear that she was trying to have Sydney killed. Katya gives Syd a lead.
    Roberts briefs his team about their assignment: stealing a Rimbaldi manuscript from a CIA convoy. An angry Vaughn confronts Roberts, declaring that he can't betray his agency, and that if he did this, he can't go back. Roberts responds by saying "like father like son," and that his father was a bad guy himself.

    Following Katya's suggestion, Syd goes to a repair shop and brings home a music box. Syd realizes that the box's flashing lights project a set of numbers, which Sydney researches in the CIA files. It leads to bank records containing payments to Syd's would-be assassin - whose source has the name "A. Sloane." Since it exonerates Irina, Syd shares this with Katya.

    Vaughn and his partner infiltrate an armored van in the CIA convoy by burning a hole through the floor. Using the cold laser, they bypass security and secure the artifact. Vaughn runs out with his partner - but Dixon, who is part of the CIA convoy, chases them through a tunnel. Vaughn's partner shoots Dixon and Dixon fires back. Instinctively, Vaughn shoots Dixon. As Dixon slumps to the ground, Vaughn peels off his mask, realizing what he's done.

    Vaughn meets Roberts at a warehouse and beats him silly. He demands the truth. Roberts admits that Bill Vaughn is dead, and that the journals and pictures were a set up. He says that he works for Sloane.

    Vaughn arrives at Syd's apartment and they embrace. Vaughn says his father had been dead all along, and that he realized that the father he knew would never have walked away from the people he loved. Vaughn tells Sydney that Sloane was behind this.

    In Santiago, Chile, a frustrated agent reports to his boss that Roberts failed and the manuscript has not been recovered - he calls his boss "Mr. Sloane." This Sloane, who resembles Arvin Sloane, tells him that everything should proceed as planned.
     
  16. Another Mister Sloane
    In Krakow, Poland, men posing as airport guards abduct Professor Sinclair, a nuclear physicist. She wakes up bound in a dark room and is greeted by Arvin Sloane. Actually, it's not Sloane but an impersonator.

    Sydney and Vaughn meet with Jack. They tell him about the elaborate conspiracy behind Vaughn's search for his father. Syd adds that she also believes that Sloane was behind the recent attempt on her life. When Syd suggests they notify the agency, Jack says he will handle it.

    Jack corners Sloane, who calmly denies his involvement and points out his lack of motive. They conclude that someone is setting Sloane up.

    The Sloane impersonator (Sloane 2) shows a Rambaldi manuscript to Sinclair, saying that he needs her expertise. Sinclair says that she needs a transformer coil for this experiment to work and Sloane 2 tells her that she needs to find another way. He has his man Carter torture her.

    In the APO office, Jack tells Syd and Vaughn that Sloane is not behind these conspiracies. They then use a handcuffed Roberts to confirm that APO's Sloane is not the man who hired him. Sloane orders the team to find the phony and they persuade Roberts to meet with Carter about the transformer coil.

    With the APO team undercover, Roberts walks in a hotel lobby carrying the transformer coil in a secure case. Vaughn tells Roberts that when Carter comes, they'll move in and make the arrest. A man approaches Roberts, saying he's there to make the swap - but the exchange should take place in the penthouse. Though concerned that it wasn't Carter, Roberts complies.
    As Roberts rides a glass elevator up to the penthouse, Syd sees Sloane 2 on his way down in another elevator. She reports it to Sloane, who predicts that Sloane 2 will cut the cable. As soon as he says this, Roberts' elevator crashes to the ground. Carter retrieves the coil, which he hands to Sloane 2.

    At the APO office, Sloane suggests excusing himself from this mission since it concerns his past obsession, Syd urges him to stay so they can anticipate Sloane 2's next move.

    After leafing through a Rambaldi manuscript under close surveillance, Sloane tells the team that Sloane 2 is constructing an energy source that requires the transformer coil. To do it, a nuclear physicist specializing in quantum electrodynamics is needed, and Jack adds that Dr. Sinclair, who fits the bill, disappeared last week. Sloane further states that the experiment needs Zanthium 242 to be successful. He calls a Sicilian contact who trades illicit chemicals and confirms that an "Arvin Sloane" ordered a large amount of Zanthium, to be shipped the next morning. Sloane travels to Sicily to intercept the shipment and find out where it's headed.

    Disguised as delivery agents, Sloane and the team arrive at Sloane 2's facility in Chile. The team splits up with Sydney and Sloane going to the lab; while Vaughn, Weiss and Nadia attempt to rescue Sinclair.

    Sloane helps Sydney break into the lab, where they recognize the Rambaldi energy source, a rotating red ball hovering over magnets. Just then, Vaughn radios to say that Sloane 2 and his henchmen escaped with Sinclair and are heading her way.

    Sydney battles the thugs as Sinclair hides and Sloane 2 escapes. Carter arrives at the lab and mistakes the real Sloane for his employer. Sloane shoots him in the kneecap and demands to know what's going on. Carter babbles about immortality, to which Sloane replies that Rambaldi's secrets would never be revealed to such a fool. Sloane beats him silly.

    Nadia arrives at the lab, sees the Rambaldi experiment before her. She also sees the darker side of Sloane - enraged and blood-spattered. He turns to Nadia and says quietly, "It's all over now."
     
  17. A Clean Conscience
    The APO team watches footage of an explosion at the Indonesian embassy in Copenhagen that killed 15 people, the work of terrorists headed by Milos Kradic. Sloane says that an agent named Thomas Raimes is undercover within the organization. Although Raimes warned Langley of the attack, he failed to prevent the blast or follow up with his handler. They speculate that Raimes might have been caught or killed.

    Sloane tasks Dixon and Vaughn with capturing Kradic. He asks Sydney and Jack to run operations, though they have yet to find out Kradic's motives.

    Sophia, the headmistress who took care of Nadia in the orphanage, phones to say she's coming to L.A. When Syd and Nadia meet her at the airport, she's wheelchair-bound and covered with bruises.

    Sophia tells Nadia that she was attacked in her home and doesn't know why. Sloane comforts her, clasping her hand. Later, he peels off a thin layer of latex from his own hand and has Marshall check Sophia's fingerprints. Sophia gives Nadia a necklace reminding her of their past.

    Jack receives treatment for his radiation poisoning. His doctor, Atticus Liddell, warns him of side effects and advises him to make peace with Syd - because the end may not be far off.

    In Amsterdam, Dixon tells Vaughn that he's previously worked with Raimes. They corner Raimes in a club and ask why he didn't stop the bombing. Raimes says that the 15 civilian deaths were necessary in order to find out what Kradic wanted -- Hydrosek, a water-based weapon developed by Indonesia that could wipe out entire eco-systems and kill half a million people.

    Dixon and Vaughn inform APO that Kradic bombed the embassy as cover for the intel theft. Since embassy protocol dictates that when a bomb goes off, all confidential intelligence goes to offsite servers, the recent explosion triggered these protocols. APO concludes that Kradic must've intercepted the outgoing data, which includes the location of Hydrosek, and he is now forming a team to steal it from Indonesians.

    Raimes says their only option is to make Kradic lead them to the weapon. Dixon agrees, and when Raimes says that Kradic is about to meet Halsey, a hacker he's hiring for the first time, Dixon suggests switching the hacker with an agent. After they nab Halsey, Dixon approaches Kradic in the club and convinces him that he's the hacker.
    Sloane approaches Sophia and demands to know why she really came. He says that he knows about the man she killed. Sophia says the man was a danger to the girls in the orphanage. She also adds that she wanted to protect Nadia, so she changed Nadia's last name -and that her attackers in Lisbon were really after this information. Sloane reveals that he knows who's after her.

    In the office, Jack tells Sydney that the embassy transmission Kradic had intercepted came from a network tap that they can still access. When Syd leaves the room to look for Marshall, Jack scratches and probes his palm and finds a computer chip stored in an embedded capsule.

    Jack sees Dr. Liddell who tells him that this device regulates his medication, and that the procedure was explained to him. As Jack says he cannot recall this, the doctor reminds him that memory loss is a side effect and admits that Jack's condition is progressing quicker than expected.

    Syd reports that Marshall located Hydrosek in a manufacturing plant in Peru. Unfortunately, Kradic beat them to it. They decide that the best course of action is to keep Dixon in play.

    Dixon tells Raimes that the embassy deaths were unacceptable. When Raimes says that they were collateral damage and that Dixon has gotten soft, Dixon explains that his wife was accidentally killed during a mission.

    As Kradic, his team, Raimes and Dixon approach a plane, one of Kradic's men intercepts a communication from a lurker with Coke-bottle glasses, regarding Dixon's embedded status. Knowing now that one of them is an agent, he orders his men to kill them both.

    Raimes punches a thug, grabs a gun and shoots the others as he's wounded. Dixon, still keeping his cover, pretends to turn against Raimes - who is sacrificing himself for the mission to continue. Knowing that Vaughn is on standby to save Raimes, Dixon shoots Raimes and boards the plane with Kradic.

    Jack takes Sydney in a room with Sloane and Nadia, and the men tell their daughters about info they've gathered about Elena Derevko. Elena disappeared 30 years ago, Sloane says, and she has been surveilling them for a decade. In fact, she might be responsible for the attack on Sophia. Her motives and location are unknown but they're doing everything they can to find out.

    Unbeknownst to Nadia, the necklace she's wearing - the gift from Sophia -- transmits this conversation to … Sophia. She contacts Coke-bottle glasses and tells him that she'll contact him once she has Kradic's final destination. He responds by saying, "I won't let you down, Elena."
     
  18. Mirage
    Posing as a waitress at a Vienna club, Sydney serves drinks to Kradic's crew, which includes an undercover Dixon. Syd reports to APO that she overheard Kradic tell Dixon that the Hydrosek will arrive soon. Sloane realizes that Jack did not arrive that morning.

    The lurker - call him Coke-Bottle Glasses - has followed Kradic from Amsterdam and begins planting explosives in the club. Vaughn, observing by the bar, sees two suited men carrying a briefcase containing the Hydrosek.

    Coke-Bottle Glasses (CBG) puts a glass down on Sydney's tray. Realizing that it's a bomb, she throws it to an empty corner, where it explodes. CBG detonates another bomb and, as the crowd panics, he grabs the briefcase and heads toward the exit.
    Syd tackles CBG and they exchange blows as the Hydrosek case skids across the floor. He escapes. Dixon shoots a thug about to kill Vaughn as he goes after the briefcase. Kradic gets to the briefcase first and runs.

    Dixon and Vaughn follow Kradic into the basement. Cornered, Kradic threatens to drop the Hydrosek in the filtration grate of the city's drinking water. Dixon pretends to lower his gun, then shoots Kradic.

    After learning of CBG's failure to steal the Hydrosek, Sophia invites Nadia and Weiss over for dinner. Upon their arrival, Sophia takes Nadia's belongings - which include a laptop - to a back room. CBG emerges from the shadows and hacks into the laptop, gaining access to APO files.

    At APO, Syd tells Vaughn that she hasn't seen her father in two days. They go to his apartment and find a notebook with recent records of Jack's vitals. Inside the bathroom, they find containers of medication and blood-soaked bandages in the trash can.

    Jack visits Dr. Liddell, who says that years ago during an experiment he discovered that a lethal dose of an alkylating agent cured a few genetically mutated rats --but 84 percent died. Despite Dr. Liddell's warnings, Jack acquires the lethal chemical.

    Based on the meds she saw at Jack's place, Syd asks Marshall to research cures for radiation sickness. Marshall reveals that Jack got sick when he removed the fuel rods in a radioactive lab in order to save Sydney. Marshall adds that there is no cure
    Sloane tells the team that Jack needs help and Syd adds no area hospitals have any record of his admittance. She says Jack's mental capabilities might be impaired at the moment and someone might be preying on him, promising a cure.

    Jack returns to Liddell's office. Meanwhile, the APO team locates Jack's car in a seedy neighborhood. Syd and Vaughn drive to the location and arrive at an abandoned building, where they find Jack on a bed in the middle of a big empty room. He injects himself and begins convulsing.

    At the APO office, Vaughn explains to Sloane that Jack thought he had a cure, and unfortunately, Jack's condition is irreversible after 72 hours. Vaughn also mentions that Jack has been suffering from hallucinations and woke up briefly to look for a "Dr. Liddell." Sloane tells the team that 25 years ago, Liddell developed a thesis on the treatment of genetic mutations. He went to the Soviet Union in 1981 to spy for the US. When his cover was blown, Jack's extracted him and gave him a new identity. Only Jack knows where Liddell is.

    Jack wakes up and talks to Sydney, referring to her as "Laura," Irina's cover name. Sloane suggests using these hallucinations to convince Jack that he's living in '81 -- specifically, the day he extracted Liddell from Russia. He proposes recreating Jack's surroundings to guide his delusions and make him reveal where the actual Liddell is located.

    Looking like Irina, Sydney enters a room built to resemble her old house. As the team observes, Jack responds to the scenario. Vaughn calls, pretending to be Jack's handler, and asks what arrangements he needs to make for Liddell. Jack reveals where Liddell should go -- in code.

    Believing that Syd is his wife, Jack tells her that he needs to leave town and help Liddell get a new identity in Finland. Jack continues on about his deep regret of missing Sydney's birthday and his lack of involvement in her life. Syd listens, deeply touched.

    Marshall asks Nadia why she requested that the Hydrosek be moved. Realizing that someone has hacked into the system, Nadia and Weiss go to the facility where the Hydrosek is stored and find that it's been stolen. CBG lies dead in front of the vault.

    Syd finds Dr. Liddell in Helsinki. He accompanies her back to APO and sees Jack, who asks if he's cured yet. Liddell answers, "Not yet… but I'm going to make you better."
     
  19. In Dreams...
    Sloane's impostor (Sloane 2) arrives at an Italian monastery to discuss with Father Kampinski his experiments on breeding the aggression out of bees. As Kampinski shows him a supposedly extinct orchid mentioned in Rambaldi's Vespertine papers, Sloane 2 offers 50 million dollars in exchange for a cutting and the text. Denied, Sloane 2 has an accomplice trigger Rambaldi's Mueller Device, which causes the bees to attack and sting the monks to death.

    Sloane informs the team of the orchid theft and orders them to recover the orchid and find the impostor. Marshall says that this orchid has properties that heighten receptivity. Privately, Jack confronts Sloane, blaming him for this predicament.

    The team sets a trap for Sloane 2, bringing him out by pretending to put the Vespertine text up for auction in Paris. Via surveillance, Dixon and Vaughn chase a man attempting to steal the papers. They stop a delivery truck. In the back, they find Sloane 2.

    During questioning, Sloane 2 invites Syd to work with him. He proposes eliminating the world's bad guys and fostering harmonic coexistence by administering the orchid extract to the general population via drinking water.

    Marshall points out that Sloane 2's brain patterns are identical to Sloane. He also recalls working on an SD-6 program for brain imprinting that Jack says was run by Calvin McCullough, a senior partner in SD-6. Project Brainstorm's purpose was to explore experimental technologies for interrogation, brainwashing and transferring memories. They conclude that finding McCullough will lead them to the orchid.

    Vaughn and Dixon approach McCullough in Buenos Aires. He admits that he made Sloane 2 believe that he is Arvin Sloane, but that Sloane 2 double-crossed him and kept the orchid for himself. As he calmly adds a packet of cyanide to his coffee, he declares that his employer wouldn't let him be interrogated. He drinks up and dies.
    Sloane confesses that through Omnifam he contaminated the drinking water of 400 million people worldwide as the first phase of creating a more peaceful species of human. The second phase, based on Rambaldi's teachings, was to introduce the orchid's nectar into the water supply. But without the orchid, Sloane's attempts at duplicating the formula failed. Now that Sloane 2 has the orchid, however, he has only to drop the nectar into the water supply to bring the affected people under his control.

    Marshall tells the team that Sloane 2 was created from Sloane's own brain scans. He postulates that the Sloane clone won't reveal the orchid's location unless he stops believing that he's Arvin Sloane. The only way to do this, he says, is to shock Sloane's personality out of him using a traumatic memory. In order to present the most vivid memory, Sloane must relive the past.

    Jack hypnotizes Sloane and guides him through his memory. Sloane's sees his pregnant wife Emily and they decide that their daughter will be named Jacquelyn. They are devastated when Jacquelyn dies shortly after birth.

    They upload this painful memory to Sloane 2, who suddenly reveals that he's a prisoner of war named Ned Bolger. He says that the orchid is located in Switzerland. Shortly thereafter, he switches back to the Sloane 2 personality and breaks down.

    Sloane refuses to wake up, preferring to alter his memory and live on happily with Emily and a healthy Jacquelyn. Forcing him awake, Marshall says, may kill him. Nadia nonetheless wants to get him back. She gently tells Sloane that he can't stay in his dream because his must undo what he's set in motion. When Sloane admits that he's ashamed of his past, Nadia says she believes that he can redeem himself.

    Sloane awakens and Nadia embraces him. Alone with Jack, Sloane reveals that Rambaldi meant nothing to him until after Jacquelyn died, when he used the writings to fill the hole in his heart. Seeing Ned showed him how much of himself he had lost. He promises to rectify his misdeeds, though every day is a struggle.
     
  20. The Descent
    A tactical group infiltrates the DSR and steals the Rambaldi artifacts. Meanwhile, Sophia says goodbye to Nadia and Sydney, telling them that the Lisbon police confirmed that it is safe for her to go back home.

    In the APO office, Vaughn plans to propose to Sydney and asks for Jack's blessing. As Jack begins to express his disapproval, a team of CIA agents arrive in the office with a search warrant.

    Director Chase looks for Nadia in Syd's apartment. When Nadia confirms that she is the only one who has access to her laptop, Chase accuses her of overwriting the DSR security system by deactivating the alarms. Just then, an agent finds the bugged necklace that Sophia gave to Nadia.

    Jack and Sloane arrive at the apartment. They then realize that Sophia must be the reason why several missions have been compromised. Jack postulates that Sophia is Elena Derevko, who unfortunately, had found them first. He points out that the string of orchestrated events -- Bill Vaughn's journal and Sloane's clone -- were her handiwork. Sloane adds that they can't let her assemble the Rambaldi artifacts. Later, Sloane tells Nadia that Elena will go to Lazlo Drake with the Rambaldi pieces.

    Nadia flashes back to a year earlier in China, where she and Sloane met Drake. Sloane explains that Drake discovered a manuscript - a template describing how Rambaldi's artifacts should be assembled, bringing forth the final prophecy. Drake is taken with Nadia, but he refuses to share information since Sloane is still missing one artifact: the Sphere of Life. He says that Nadia is the only one who can retrieve the Sphere.

    They then go to an underground cave in Sienna, where Sloane asks Nadia to obtain the Sphere in a box perched on a podium that is surrounded by stained glass floors. Nadia carefully walks on the creaking glass and opens the box. As she touches the Sphere, she sees a vision of destruction and refuses to bring the Sphere to her father. Sloane calls her a coward and attempts to walk across the glass floor by himself. The floor shatters and he falls through, impaling him. Nadia nurses him back to health.

    In the present, Sloane tells the team about Drake and adds that in Elena's hands, Rambaldi's endgame is apocalypse. They attempt to locate Drake, who has been in hiding with the aid of Grayson Wells - a billionaire who financed Drake's earlier Rambaldi research. Sloane tasks the team to approach Wells, and says he will talk to Drake himself.

    At Cannes, Sydney poses as a spoiled heiress in a jewelry store and brushes past Wells. She pretends to purchase a bracelet and charms Wells into putting it on her wrist. As Wells sees a Rambaldi mark on Sydney's hand similar to his, he offers to buy the bracelet for her. Later, Wells now tied to a chair, Sydney phones Sloane with the location.

    Syd meets Sloane in Mexico. When she expresses her suspicions, Sloane tells her that he would never do anything to hurt Nadia. They approach a trailer; Drake lies dead inside. Syd finds a surveillance video recorded from a hidden camera, revealing Elena chatting with Drake. Before Sydney can listen to their conversation, Sloane stabs her with a tranquilizer and heads out to Elena's office.

    Jack arrives in Katya's jail cell and demands to know Elena's operations. In response, Katya asks for a full pardon and immediate release. When Jack says he'll do everything he can, Katya reveals that Elena has been acquiring artifacts for several years through her front -- The Covenant. Katya says she can help him find her, but it is only Irina who can stop Elena from acting on her end game. Jack, if you recall, murdered Irina.

    Finding out that Elena is in an industrial facility in Prague, Syd, Nadia and Dixon prepare to infiltrate. Dixon arrives at a loading dock and watches the guards put a prisoner in the van. Sloane emerges from the shadows and points a gun at Dixon. He asks for Dixon's trust and tells him to get out of there. Suddenly, Dixon is shot from behind by Elena and Sloane looks at Dixon regretfully before leaving.

    At the hospital, Syd and Jack observe as Director Chase cares for Dixon. Jack admits that he lost sight of the one thing he knew to be true -- that Sydney's mother, Irina, would never hurt Sydney.

    Jack crosses paths with Vaughn in an elevator. He says that if Vaughn honestly believes that he can make Sydney happy, then Vaughn has his blessing.

    Dixon regains consciousness and talks to Nadia and Sydney. He tells them that he saw a shackled prisoner at the loading dock: Irina Derevko

     
  21. Search and Rescue
    Jack regretfully recalls the time he shot Irina in Vienna, under the belief that she was responsible for putting a hit on Sydney. Syd arrives in the office and tells Jack that Dixon, who claims that he saw Irina, could be delusional. Jack says that he killed a woman he believed to be Irina, and reminds Sydney of the doubling technology of the Helix Protocol.

    Marshall bursts into Jack's office and reports that they found Elena's associate, Lucien Nisard, who worked with The Covenant. Jack tells Marshall to check the Blackwell Index via Sloane's computer.

    Suddenly, TV screens in the APO office display news reports about Sovogda, a Russian city in chaos. Marshall then receives a video feed from a hacker in Moscow, showing raw footage of anarchy. The footage reveals a giant red ball hovering in the sky - Rambaldi's Mueller Device.

    The team believes that Sloane and Elena have activated the Rambaldi device in Sovogda, which resulted in unbridled aggression in its citizens. They conclude that the city's contaminated water supply combined with the chemical properties of the orchid made the residents susceptible to the Mueller device. The only solution is to disarm the device properly -- and Irina Derevko, who is being held prisoner by her sister, is the only one who can do it. They need to force Lucien Nisard to reveal her location.

    Vaughn comforts Sydney and tells her that they're going to get through this. As he was about to bring out the ring and propose, Marshall arrives and says that it's time to leave.

    They arrive at a dance club in Ibiza, where Sydney goes in with Vaughn and spots Nisard. Syd and Vaughn make out -- and as Syd makes eye contact with Nisard, she invites him to join them. They go to the bathroom where Sydney and Vaughn transmit his PDA contents to Marshall. When they find that the Helix Protocol is mentioned, Syd dunks his head in the toilet and asks about Irina. Nisard confesses that Elena doubled Irina and confirms that the real Irina Derevko is in Guatemala

    When Syd and Nadia arrive in Tikal, Guatemala, Jack guides them via a satellite layout of the camp until they locate an underground cell. They open the hatch, finding Irina.

    "I knew you'd come," Irina tells Sydney, and they escape. As guards chase them, Sydney walks into a trap and is strung upside-down. Irina rescues Sydney while Nadia holds the guards off. They run to escape as more guards arrive. Syd throws a grenade at them and, along with Irina and Nadia, escapes on a raft.

    On the plane, they tell Irina that Elena and Sloane have enacted their plan. Irina shares that she found a Rambaldi manuscript - Il Diluvio - which revealed Rambaldi's desire for a complete cleansing through apocalypse. Though Irina destroyed the manuscript, Elena tortured her to get the info, forcing her into dozens of cardiac arrests. Irina admits that she finally broke and told Elena everything. Now, they must go to Sovogda and stop them before they move to another city.

    Irina breaks down when she realizes who Nadia is. Later, as they look over a map, they agree that Sloane and Elena must be somewhere in Sovogda but safe from the Mueller device. Suddenly, Jack gets a call from the pilot, and their plane is diverted by official orders from Langley.

    As they land, police cars arrive and arrest Irina, who is still a fugitive. Syd goes to Director Chase and argues that Irina is the only one who can help them. Chase says the matter will be resolved in a few hours by a Russian air strike. Syd points out that this will release toxins in the atmosphere and results will be catastrophic. She begs Chase to trust her.

    As the team prepares to parachute into Sovogda, Vaughn pulls Sydney aside and says that he wants to spend the rest of his life with her. He gives her the ring and asks her to marry him. Overwhelmed and delighted, Sydney kisses him and tells him to ask her again on the beach.

    The plane's rear door opens and Irina, Jack, Vaughn, Nadia and Sydney jump out

     
  22. Before the Flood
    Jack, Irina, Nadia, Vaughn and Sydney land in the city of Sovogda. They walk through a deserted street littered with corpses and burning cars. As they wait for the Department of Special Research team, they speak to Marshall and Weiss, who report that Director Chase is trying to convince the Russians to call off the air strike.

    At APO, Marshall and Weiss use the Blackwell Index to blackmail a Russian minister into giving them the access code to a Russian satellite. They soon discover that Elena is uplinking to the Russian network.

    Syd follows a DSR signal, which leads to a severed arm. Suddenly, a CIA agent named Brodien emerges from the shadows and tells them that his DSR team was ambushed by the infected mob, which has left thousands dead. He reminds them that the Rambaldi device is broadcasting a subaudible frequency that physiologically alters people who drink the water. The symptoms, he says, are irreversible.

    He also says the epicenter is located over the Oransky building, and that while he has taken out the city's power grid, the device is still running. Irina suggests that it has been modified to run using an internal energy source. They decide to take the subway, as it is the quickest way to the building.

    Elena learns of the APO team's arrival. When Sloane volunteers to lead the assault team, Elena tells him to bring Nadia back and give her the option to join them.

    As the APO team approaches the subway tunnel, an infected man impales Brodien with a rod. As Jack, Vaughn and Irina try to start the train's emergency battery system, Syd and Nadia go inside the train's switching room to force the train to stop at the Oransky building. Irina urges Vaughn to tell Syd "the truth." Syd tells Nadia that Vaughn asked her to marry him. Nadia and Sydney split up to manually adjust the switches.

    Sydney returns to the train first while Nadia, down the tracks, flips the switch. The train rolls down the tracks as a mob chases Nadia. Jack refuses to stop the train because if he does, it won't start again. Sydney stretches to pull Nadia to the train but she's tackled by an infected madman. Irina tells Syd that Nadia is still alive.

    Sloane kills Elena's men and waits at the station. He tells them that Elena has primed the world's drinking water. As Syd voices her suspicions, Sloane says he allied himself with Elena to put an end to this himself, but Elena built in a security device that Sloane couldn't crack. Jack punches Sloane and takes control of the team.

    Marshall reports that Elena is going to use the Russian satellite to distribute the Rambaldi frequency worldwide. Once it goes online, the Rambaldi signal will be broadcast and everyone will be infected. Irina says they need to shut down the device from the roof of the building

    Jack tells Sloane to take them to Elena. Sloane cautions that once they disable the device, the toxins will dissipate in the atmosphere and the person who disarms it will only have a few seconds to run. When Irina insists that she can cut the wire and reverse ionization, Sloane reveals that Elena had changed the wiring scheme as a fail-safe. Irina orders him to take her to Elena so she can force her to reveal information while Syd disarms the bomb.

    Nadia fends off the mob and wanders the streets. She approaches a wounded man who surprisingly holds a gun to her head and takes her to Elena. When she refuses to join Elena, Elena injects her with the contaminated water.

    Before Syd heads out to the rooftop to disarm the bomb, she turns to Vaughn and says, "Just in case: yes, I'm gonna marry you." She wears his ring and hops into the elevator.

    Marshall tries to connect to the satellite. Weiss says the President and his Cabinet are being evacuated to secret bunkers.

    Sloane arrives with Vaughn, Irina and Jack. Vaughn searches for the relay room. They strap Elena to a chair.

    Sydney reaches the rooftop and opens a hatch that revealed hundreds of interwoven wires. Nadia, now infected by the device, walks toward Sydney. Jack and Irina urge a reluctant Syd to take her out. The sisters battle. Vaughn blows the relay but nothing happens. Irina tells him to get to the roof. Sydney knocks Nadia out and chains her up.

    Vaughn arrives on the roof and realizes that Sloane is not there. Meanwhile, Irina guides Sydney in disarming the device. Irina gives her sister a chance to help them as Jack gets ready to torture Elena. When Jack pierces her with a syringe, Elena yells that Sydney should cut the white wire. Irina shoots Elena in the head and tells Syd to cut the blue wire instead and run fast -- she only has 15 seconds.

    Sydney is about to cut the wire when Nadia strangles her from behind with the chain. As Sydney starts to suffocate, Sloane arrives and shoots Nadia. Syd sees Vaughn and tells him to take the wounded Nadia with them. Syd then cuts the blue wire and runs away as the device starts to fall apart. They race inside the quaking building and sprints toward a shelter -- they have just saved the world.

    Jack advises Irina, who is wanted by the CIA, to disappear. They kiss. Irina tells Syd that she's proud of her. She says that Syd may not see her on her wedding day, but she'll see Syd.

    Later, Syd visits Sloane in a jail cell, tells him that Nadia is stable, but they're still trying to find an antidote. The Russian military executed all survivors to support their claim that it was a chemical explosion. Sydney has arranged for Sloane to see Nadia. She believes he was trying to do the right thing. Sloane thanks her.

    Driving in Santa Barbara, Syd suggests to Vaughn that they blow off the big wedding and elope. After professing their love, Vaughn reveals that that he was a bad guy before they met. He continues to say that to begin with, his name is not Michael Vaughn. Before Sydney can react, a car collides with theirs
