JC and Burton make their way back to the room they've been in. They hide in the wall as a couple Russians come in looking for them. One guy leaves, but when Laszlo hesitates, JC takes him hostage. Though it's not totally clear why, considering Laszlo didn't see them and seemed to be on his way out.
Szymanski and Carter head to Yogarov's crazy fancy office to question him about Benny's murder. They ask where his son was, and Ivan says he was here working all day. Carter's not so sure Yogarov's the best alibi for his son, however. "With all due respect." Yogarov suggests they come back with a warrant. Szymanski tells Ivan there are no winners in this war, only dead soldiers. But Ivan says this war was started by Elias, who came into the neighborhood and started killing and stealing. Ivan excuses them both so he can host an event. But when they leave, he just sits back down at his desk. What a good host.
Burton and JC head out with their hostage, Laszlo. JC calls Bench to ask him to get word to Carter that their bodega shooters are inside The Double Bs. Bench is on it, and he'll also make sure Fusco meets them at the ferry. They exit the building entirely too easily, and tell Laszlo they're crossing the river. Bench listens in as someone in the SUV says he got a text that they're heading to Pier 11, and they need to get over there now.
Carter and Szymanski have arrested Peter Yogarov and the others. Szymanski asks if she knows who called it in, and she says he has an idea. Yeah, that guy who keeps handing you criminals? What a pain in the ass. Fusco's waiting on the pier when Bench calls him to scold him for not being trustworthy, since he's clearly the leak to the guys in the SUV, right? But Fusco protests -- and then one of Elias's men comes up and beats him up, and hangs up his phone call. Bench hasn't quite put together out Usual Suspects ending quite yet -- but maybe you have. (I hadn't when I first watched, but my husband did. I thought he was such a genius, but it all seems so obvious now.)
On the ferry, JC tells Burton he's going to hand him off to a detective he can trust when they get to the pier. He calls Burton "Charlie," because they're becoming such good friends, and tells him he needs him to testify. Laszlo, handcuffed to the ferry (do they let you do this on a ferry ride on the East River? It's nothing like the Staten Island, I guess) glares at them as they talk. Burton tells JC he doesn't want to see these "cretins" in his town anymore, which makes it seem like he just agreed to testify.
