Bruce, unfortunately, can't forget to breathe. He has Loki's trinket, but that magic could run out if he isn't careful, so even now he has to watch himself, to pull back a little on how excited he is to see Clint... But oh God, is he excited, and he kisses him hard, seeking comfort, seeking to seal them both back together. His breath comes out steadily against Clint's cheek, but then that must be familiar too, the way Bruce always kisses, with the hint of tipping over into something more, but always with one foot on the ground.

He lets the kiss break finally though, but sets their foreheads together, fingers stroking the back of Clint's neck, sliding up into his hair; his other hand cups his jaw, thumbing over it gently.

He'd known that losing Phil again would be a blow for Clint, whether he was his Clint or not, and Bruce knew living through that had been hell for himself; he can't imagine Clint, so used to having Phil nearby, took it any better.

"I didn't know. I'm sorry. I should've asked, but I was afraid you'd look at me like..." Like Tony had. He inhales and shakes his head, his nose bumping Clint's. "I couldn't have handled that."
