Bench calls JC's cell phone as he watches some guy picking up a prostitute. He tells Bench that he's taking care of a side project while Tillman's working. Bench fills JC in on Carter's obsession with him, and says he needs to have a plan for when she catches up to him. JC says he's taking care of it, by making a new friend (the guy picking up the prostitute, I presume, since JC's snapping pictures of the deal) on the police force. He says the friend's going to help with their problems with Carter and Fuscoe.

JC follows Tillman after work to a support group of some type. When he sits down, a woman is crying and talking about being assaulted. Tillman gets teary and uncomfortable, and finally gets up and leaves. JC gets up and follows her to the coffee machine. He makes small talk with her about how coming to these groups should make him feel better, but it makes him worse. He asks if she knows that woman talking in there. She says no, but she knows someone like her. She asks why he's here, and he says he lost someone very close. She says she's sorry, and he goes on that not a day goes by when he doesn't think about what he might have done. Tillman says it took her years to piece together what happened with her "friend," and she thought she'd put it behind her. Until she saw him a month ago, out on a date at a French place. He looked content, and her world shattered. She chokes back tears and apologizes for telling him all this. He says everyone needs someone to talk to. He introduces himself as "John," and she says she's "Kate Leman."

Back at the Library, JC fills Bench in on Benton's M.O. He takes pictures with these women, gets them to do cocaine, then slips them a sedative and rapes them. In the morning they're too afraid to come forward and implicate themselves because of the cocaine. JC says Benton gets off on this, and he's not going to stop. He asks Bench if he got a hit on the name Kate Leman. There are three in the area, but two don't seem related. The third has a P.O. box a block from Tillman's hospital and recently signed rental agreements for a van and a vacation home in Montauk. JC checks out the vacation home and finds a closet full of lye. He tells Bench it's everything she'd need to dissolve the body for good. Bench says he'll refrain from asking how JC knows that. JC says Tillman planned this to a T, and is going to get away with it. Bench is beginning to think she should, but JC says she's not a killer and this will ruin her life. He has to find a way to make Benton disappear first.
