The team watches the surveillance video and see that Ian ran up to the roof. Marshall Janet Galvin arrives and says it doesn't take much for people like Ian to flip to the dark side.

Charlie and Nikki watch the news about Ian. Nikki says she doesn't think Ian is a bad guy. After analyzing Ian using game theory, they figure that Ian's goal is to punish someone and not to escape.

Don and Colby wonder if Ian went down an elevator shaft. Janet meets them the team and hands them the blueprints for the prison. Don and Colby find an airduct with a piece of prison uniform inside it. While looking for Ian, Nikki tells David that Ian is the last person she would suspect as being corrupt. Colby and Don are ambushed by Ian in the break room. Ian takes Colby hostage with his gun. Don presses the alarm and brings in the rest of the team. Ian tells Don he should know what he is capable of. Don orders the team to get out of the room. Out in the hall, Don is upset he didn't take the shot when he had the chance. Inside the break room, Ian handcuffs Colby to a pillar. While he booby traps the door, Ian tells Colby he didn't kill Costello and there is no way he is going to jail.

David calls Ian in the room and asks how they can get Colby out safely. Ian demands to contact Charlie on a video feed. Nikki takes the phone and tells Ian it has been a long time since they talked. She tells him taking Colby hostage doesn't help his case. Ian says if he doesn't see Charlie soon, it is going to get messy in there.

The team brings Charlie to the FBI building where he gets to a computer and contacts Ian. He shows Charlie that Colby is safe. Ian apologizes and says he needs his help. He says he suspects Garcia is hiding from Salazar until he is able to testify against him. Ian suspects Garcia is using another person's identity to hide in the prison. He explains the prison IDs are easy to take off and switch since there are six thousand prisoners.

Charlie tells Don and Nikki that Ian is convinced Garcia is still in the prison. They examine the surveillance tape that supposedly shows Garcia escape, but determine it wasn't him who left the prison. Charlie compares jails to the reality show Survivor. He believes Garcia built alliances with people who were most beneficial to him. They search for people who Garcia could have contacted in prison.
