It hurt, but Steve was brave and careful not to look at the needle because it made it better not to look. Tony put a plaster on the spot and Steve rolled down his sleeve, pulling the sweater around him some more. Because cold was his natural state of being, it was hard to be warm when there wasn't anything of him.
He nodded quickly, because he knew that, he knew Tony wouldn't hurt him. This place felt safe, this room, his room. But why couldn't he remember it? Why did yesterday feel so long ago? He had a lot of questions.
"I got to go find Bucky," he said quickly, jumping to his feet. Steve was at the bathroom door in a flash, before he returned for the inhaler and raced back again but paused in the doorway to look back at Tony. "I'll come back, promise," Steve said sincerely. Because that seemed really, really important.
