While Carter engages in mental warfare with the FBI to help Reese evade Agent Donnelly's narrowing focus, Reese crosses paths with foes both old and new. Meanwhile, Fusco is forced to fly solo to help the team's newest POI: supermodel Karolina Kurkova.
Prisoner's dilemma usually refers to a component of game theory which explains complex social interactions resulting in gains for one or more party. The prisoner's dilemma is a situation in which two players each have two options whose outcome depends on the simultaneous choice made by the other. While the theory can be applied to many situations in daily life, it is often formulated in terms of two prisoners separately deciding whether to confess to a crime in order to gain the best possible outcome for themselves before their partner does so.
During the interrogation, many of the facts Reese gave about his alias can be linked to events in previous episodes:
Reese states his parents' names as Conrad and Laura. "Laura Reese" was the name that appeared in the press release for "Shadow Box" which was supposed to have flashback scenes about Reese's childhood.
In the flashback where John is in the Czech Republic on assignment with Kara Stanton, the camera title says "IDŐJÁRÁS KAMERA 22" followed by "SZOBA 414" which are Hungarian, not Czech, for "Weather Cam 22" and "Room 414" respectively.
