Elliot is held captive and under interrogation by government agents. Flashbacks reveal the events of the previous day. In the aftermath of the bombing, Sean is wanted as a terrorist and hiding out on his own. He cracks Anthony's phone and discovers that Elliot is an undercover cop. Jevan is visited by two higher-ranking investors, Kane and Jacob, who have him thrown from his apartment window and killed. Asif's son Nasir wins the election and becomes mayor of London. Lale, disguised as a journalist, assassinates Nasir at his own victory party, leaving his mutilated corpse for Asif to find. Their arrangement complete, Lale sleeps with Sean before returning to Kurdistan. Ed meets with Marian in a graveyard, imploring her to give up Sean. The two pull guns on each other, and Ed shoots Marian, seemingly killing her. Harks informs Vicky that Elliot has been retired from duty as a police officer. Vicky visits Shannon at home, attempting to turn her as an informant. Shannon discerns that Elliot was undercover, and shoots Vicky dead. Searching for Sean, Elliot gets his location from Billy. Before visiting Sean's hideout, Elliot is picked up by Kane and Jacob, who order him to keep Alex Dumani in play and prevent Sean from standing trial, leveraging Shannon and Danny's lives to compel him. Elliot visits Sean, who at first considers killing the undercover cop. Instead he provides Elliot with a sim card containing evidence against the investors, hoping he can bring them down legally. Alex arrives at Sean's hideout, bribing Sean's doormen to let him bring a gun into the room. He plans to kill Sean, but cannot follow through with it as Sean talks him down. Elliot disarms Alex, only to shoot Sean with the gun. Police raid the hideout, and Elliot successfully smuggles Alex to safety, though Harks is killed in the process. Elliot is arrested afterward, leading to his interrogation. An agent of the investors, disguised as a nurse, secretly instructs him to claim diplomatic immunity under Panama, and his captors are forced to release him. Though seemingly working for the investors now, Elliot extracts Sean's sim card from a hiding place in his mouth. A flashback to the previous day reveals Marian survived her shooting, and she is approached by Floriana, who offers to help her.
