He realizes quickly that she's tough, but scared of something. And he says there are hundreds of people who could be after her, but he's narrowed the list to two for now: Wheeler, her co-counselor, whom she dated for awhile until she broke things off. JC notices she tries to avoid him and he pushes too hard. Plus, forty percent of murders involve some kind of romantic relationship. His other suspect is Lawrence Pope, who she's prosecuting for allegedly shooting his friends in a drug deal gone bad. Pope's gang may be targeting her. At trial, Diane questions a cop, Detective Fuscoe, who says that when he questioned Pope, he said that if he'd shot the poor bastard, he would have shot him in the head, not left him there half-dead. After the questioning, Diane catches up with Fuscoe in the hall and says he went a little off-script in his testimony, and that what he talked about could clear Pope's name. Fuscoe wonders what it matters, since they got the guy. She says it matters because it's her job to make sure the wrong people don't go to jail. Fuscoe says he thought they were on the same team, and storms off.

Finch watches her GPS back at the Library, and tells JC she's going to lockup to see Pope. JC heads there, too, and listens in as she questions Pope. She wonders who he's trying to protect, and why he's taking the fall for this. She wonders if it's his brother, Michael, and assures him he can trust her. Pope tells her to stop asking questions, because he can do this time if it means protecting his brother. She keeps pushing until he jumps up and tells her he'll shut her mouth for her if she doesn't do it herself. Guards come in and help her out, and JC thinks he has the information he needs: Pope's brother, Michael, will know who framed Pope; those are the guys who'll be coming after Diane.
