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.
NYPD. Carter and Szymanski question Peter, and she says he's on camera, plus witnesses say he and his brother were shooting up the streets in Brighton Beach. She tells him she knows Elias killed his uncle, and that he and his father and brother (is Laszlo his brother?) went to the bodega for revenge and killed Benny, the next best thing to Elias. She says that now he's trying to rub out the witness, who saw his father's face. Peter tells her they'd heard from a source that Elias was supposed to be at the bodega to meet Benny, but when they showed up they only saw Benny. The owner called and told them there was another guy.
