"Shit," Steve breathes; he knows, logically, that Bucky isn't cold, necessarily, but what ends up happening is that he unzips his hoodie and tries to get it around Bucky's shoulders all the same. Maybe the whole not getting shoved or slammed back thing is making him more stupid than usual.

He does, at least, pull his hands back when he's done, if the fabric even makes it onto Bucky's shoulders in the first place.

"I'm sorry," he says again. "Sorry. We don't ever have to try that again."
