JC's in the back of Fuscoe's cop car. Fuscoe fills him in on how to hire a shooter at this area bar call Junior's. JC heads inside, then gets thrown out on the street by a couple of heavies. They tell him they don't want to see him around here again, so he heads back in and fighting and gunshots ensue. Fuscoe watches it all from across the street, then JC rejoins him in the car, says he got a name and is ready to go. Surveillance images put us inside a prison, where JC's on the phone with Finch. He's arranged a visit with a contract killer named Solnick, who supposedly murdered the family, then got locked up for another job. Solnick's not interested in talking to JC about the family he killed in Bowery Bay, so JC threatens him with telling the gang leader who lives in his cell block that he killed his brother. Solnick gets that JC's like him: a killer, a genuine bad guy. "Then I don't have to explain what happened to those people on that boat. You already know." What JC says he doesn't know is why he let Theresa live. Solnick says he wouldn't have killed her even if they'd paid him his quote. He doesn't kill kids. But he told her that if anyone ever knew she was alive, he'd finish the job. He says he told some guy on his cellblock the same thing last week when he asked about it (which might explain why Theresa's suddenly in trouble; Solnick's blabbing his mouth about her being alive). JC asks who hired him to do it, and he says "some guy I met one time. No names. Cash." He asks who hired JC. That seems to end the conversation.

JC calls Finch. They understand now why folks know Theresa's alive, but not why anyone's after her. Finch thinks he might have a lead. He's come across one real estate investment that Grant Whitaker wasn't the sole investor in (he was sole in all the others). He bought a couple properties with a holding company called Landale. JC wants the address; he's on his way.

Surveillance footage shows us the guy getting offered his usual rate on surveillance footage earlier in the episode roughing up Deacon Page. JC, meanwhile, is outside Landale scoping it out. Finch says the head of Landale is a guy named Calhoun. JC says he's got a lot of security for a real estate developer. Then he notices Derek in Landale, and wonders why he'd turn up here. Finch says it will have to wait, because Theresa's just tried to sell those credit card numbers. He tracks down the building where the IP address she's selling from is located. JC finds her in a laundromat, and tells her she got him good last time. She starts to run again, but he says he knows what happened to her family, and he's not going to let anyone hurt her. The guy who was just roughing up Deacon clearly got the information he needed, because he comes up behind JC and tells him he shouldn't lie to kids. He points a gun at her, but JC fights him. The bad guy seems to be winning, and throws JC out the front window of the place. But once his gun's retrained on Theresa, JC sits up and shoots him in the chest. He takes off after Theresa, as the guy sits up and pulls off his bulletproof vest. JC catches Theresa and asks if she's going to trust him now. She says she doesn't know him, but he tells her she's got to trust someone. Oh, really, JC? Who exactly do you trust? It seems the only person in his life is Finch, and he's been stalking him to find out what he's hiding.
