He's hurting, clearly, and I want to go over, but I can't move.

That's ridiculous. Pull it together.

"Bucky," I say hoarsely, taking a few stalking steps until I'm at his shoulder, but once there I freeze up again. I don't move to help him stand, I don't kneel and do something as basic as put a hand on his back to try and steady him. I just stand uselessly by.
