Martin (Sandrine Holt), who is in a sexual relationship with Wellington as part of a plan to get US intelligence for the Russians. She also appears to be connected to the mysterious death of Gen. Jamie MacLendon (Robert Knepper), one of the conspirators in the assassination attempt on Keane. Carrie breaks into Martin's house to gather information, but is arrested for trespassing. Dante intervenes and manages to get her out of jail. Carrie proposes to Dante a "completely illegal" plan to connect Wellington to Martin's dealings, and Dante agrees to help. Dante, Max, and former CIA officer Thomas Anson (James D'Arcy) kidnap Martin and get her to confess her complicity in MacLendon's death, which leads to her testifying in Paley's hearings.

When Dante accuses Gromov of poisoning him, he denies it and tells Dante to call Carrie and ask her if she was responsible. Dante calls Carrie, who is picking up Frannie from school early. He realizes that Carrie is lying to him, but nonetheless he tells Carrie that Gromov is in the room with him; Gromov then kills him. Carrie opts to leave Frannie at school in her rush to the hospital, but Frannie runs after her and is almost accidentally run over by her mother in the parking
