If this is real, if this is really Steve, then it isn't his fault. Somebody came back and impersonated him, and that's the person Bucky is going to be mad at. He sniffs once, then finally pulls back after a minute of soaking up the feeling of Steve.

"You missed a lot, pal," he says, still not quite steadily. He has to wipe his face with the back of his hand. "I'm gonna have to catch you up. And we're gonna have to talk about Sam." He really doesn't want to take the shield away from the guy. Sam's good at what he does, and he's pretty convinced that Sam is the Captain America the world needs right now. But if Steve Rogers is back, the world is going to think it wants Steve back.
