It's the fact that Ratchet's ignoring him that makes York finally get up and go to the exercise room, to be honest. The pain is a distraction from how awful he feels, and if Ratchet's not talking to him there has to be a reason. Like always, he doesn't push, just does his own thing. Which in this case is pull-ups.

"It's not like I'm trying to run," he says defensively, then winces at how it came out. "...sorry. We probably need to talk."
