In the theatre, Syd opens the package — it's the head of one of the CIA agents. Shoved in his mouth is a note demanding 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 favourite 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 is also Michael Vaughn's wife.
