JC leaves the shop (it was broad daylight when he went in, but it's dark now) and checks in with Finch, hoping he's found Michael. Finch has, but someone else found him first. He patches JC in to listen to the conversation going on: Some older white guys have their guns trained on Michael. They say they're going to put a couple in the back of his head to make it look like a gang thing. Finch urges JC to do something. In the coolest sequence of the episode (and there's a lot of badassery going on this episode), JC whisper-talks he's "on it," throws some money at the driver, gets out of the cab, pulls on a ski mask, walks over to the street the bad guys are speeding down in their SUV, tosses his bag of guns aside except the one he's going to use, steps into the road in front of the SUV and shoots right into the windshield. It crashes into a parked car, and the guys climb out. JC shoots the driver in the leg, then punches the next guy who gets out. He pulls Michael out of the backseat. Michael tells him he's crazy, that they're both dead now. He asks if JC knows who they are. JC does now, since he pulled a wallet off one of them. "They're cops. Come on."
JC watches the bad cop he punched with several other cops, taking pictures. Then he meets up with Finch in Central Park and asks him exactly what he's gotten him into. Finch says that's the whole point; he hired JC to help him figure that out. JC gives Finch the photos he took earlier, and says they're up against a group of corrupt cops. He says Stills (the guy he punched last night) is Narcotics. They get word of deals, and steal the money and kill the witnesses. Then they get Fuscoe (who's with them in JC's pictures) to frame up the guys in court. JC tells Finch he knows nothing for certain, though, because Finch won't tell him where he's getting his information.
