Arthur almost points out that if he stays, they'll both be in trouble for the situation, given they're not contracted. But, at the same time, he remembers they're both probably up shit creek anyway already, so what's another citation to add to the list, right?

Even if he doesn't think quite like that, no doubt Eames would wave it off as such.

So instead of arguing right off the bat, Arthur scoffs as he starts toweling himself off. "Worried I'll run into danger?"
