JC heads to the "pharmacy," by which he means the meth lab they walked by on their way in the building. He sort of John Waynes it up in this scene, using the term "fella" twice and calmly threatening the guys. I would be annoyed, but JC can sort of pull that off. The guys don't believe he's as tough as he says, though, and they come after him. He obviously takes them out one by on. Then he takes some of their drugs and heads back to his new boyfriend in their seedy room. He does turn to politely thank the still knocked-out guys on his way out. He must have checked Emily Post for the proper etiquette in such a situation.
Szymanski fills Carter in on what's been going on between Elias and the Russians. I guess Elias took out Ivan Yogarov's brother last week, so this Benny killing was surely payback, and Ivan may have even been there. Carter thought the Russians were untouchable in Brighton Beach, and Szymanski says they were/ but no one knows where Elias is getting his information, so he's one step ahead of them -- and of the cops. What Szymanski doesn't get is why Elias is making a move for Brighton Beach. Carter fills him on what she learned last week about Marlene Elias's son being the bastard of Don Moretti. So Elias is coming back to clean up and claim his birthright.
Seedy hotel room. JC fills Burton's wound with cocaine, and Burton says there's a first time for everything. Then JC glues the wound closed. Burton asks if JC learned all this in hero training, and JC says "Something like that." Then Burton gives him a heartfelt thanks, and tells him if it weren't for JC, he'd be dead right now (note: This is foreshadowing). JC asks Burton if he's ever used a gun. Burton resists and thinks JC should keep it, but JC shows him how simple it is to use and convinces him to keep it on him. Burton asks if JC thinks they'll get out of here, and JC says their chances are better since the cocaine.
