Wash pushes York back against the wall again, because he is not bailing on the situation if Wash has anything to say about it. "Like hell you are. You're going to walk back in there, sit next to Locus - not on him, next to him - apologize for making assumptions, and then fucking talk to him like I've been telling you to do for days!"

He's keeping the volume down, which means the intensity has gone up. Wash is not taking no for an answer at this point.
