Steve laughed a little, softly, happy to distract him while the doctor took care of things. "You might regret it," he teased, but if Bucky really wanted to meet Stark, he'd see what he could do. Even Stark had a heart somewhere under all that metal. He just needed to make sure Bucky was stable enough to handle him. "He's a handful." And then some.

He glanced down at the doctor, frowning a little in concern, but actually, he was glad that someone would get Bucky help if he needed it. He'd keep an eye on Bucky, too, but he didn't quite want to say so out loud - Bucky was an adult. He didn't need to be watched like a child. More like a friend. Not to mention an assignment. "Thank you, doctor. We'll take it easy for a couple of days." Maybe Bucky could concentrate on getting Penny settled, to take his mind off everything else.
