He's tempted for half a second to undo one button just to see what Clint does but puts it aside. If Clint was serious about that he would've made a move already. He suspects that Clint needs time to think. In the field he'll throw himself at danger with very little forethought but he's going to think about this now.

Phil settles his fingers in Clint's hair and pets through the short stands slowly. It's soothing for him as well, actually. The weight of Clint's head in his lap, the warmth of where their bodies press together, and the steady rhythm are permission for him to truly leave Agent Coulson behind and just be Phil.

He slumps a little into the couch cushions and watches other people be absolutely terrible at solving simple everyday problems that aren't in the least bit serious. And he waits to see if Clint has anything else he wants to get off his chest.
