Reese and Finch track former Stasi agent Ulrich Kohl (Alan Dale) across New York City. Kohl, having been secretly imprisoned by the German government for twenty-four years, has finally escaped and located his former Stasi team-mates - Hauffe, Wernick and Steiller, all of whom betrayed Kohl to the American and German governments in exchange for new lives in New York. Further, Kohl believes that his former Stasi colleagues are responsible for the murder of his wife Anja, who was killed while attempting to flee Germany with him. Kohl kills Hauffe and poisons Wernick, but Reese manages to save him. When confronting Steiller before killing him, Kohl learns a terrible truth – Anja is still alive, having staged her own death to escape from his atrocities. When he attempts to locate her (running into Reese instead – who he briefly connects to as a fellow spy and soldier), he also learns Anja had their child, Marie, and so sets out to find them both. Kohl finally locates Anja, having taken Marie hostage, and admits that he understands the reasons behind her flight, before raising an unloaded weapon to her, forcing Reese to shoot him dead. Kohl's predicament leads to Reese reflecting on his own life as a spy, where it is revealed that "John Reese" is an alias bestowed upon him by his former CIA partner, Kara Stanton (Annie Parisse).
