"Good, man, that's great, just keep breathing with me." Hell, it's doing Sam good, too, giving him something to focus on other than having just woken up.

Then the guy looks up, and Sam offers him a smile in the second before he recognizes him. "...Bucky?"

It's out of his mouth before his brain catches up with him. It'd make sense, why some guy dressed in Capitol clothes is having a panic attack, except - except his hair is different, his stance is different, he looks way too young. Some of that might be explained by stylists, but... His eyes are different; this might look like Sam's friend, but it definitely isn't. It throws him, probably visibly, but he recovers, offering the guy an apologetic smile.

"Sorry," he says. "You looked like a friend of mine, I - I'm Sam, can I get you to a place with a little less people?"
