Clint freezes. And he hates that he freezes, because it means he can't fully deny anything or brush it off as nothing to talk about at all. "Who said anything about 'won't'?" Sip coffee. Be casual. "Don't worry about a thing. Be back before you know it."

So it's an escape. So sue him. Spent a little time together, have plans to spend more time together than they have in what feels like an age, acknowledge they're both some form of fucked up (even if Phil seems fine, so far, even if waiting for the other shoe to drop), and it'll all work out in the end. He can escape so long as Phil lets him, because it's still something he needs help with, and it would've gotten done one way or another.

But if he spends a little extra time away than strictly needed, well. It's fine. Even if he feels bad about it. It won't kill either of them.
