He has to say something and remind himself that they are not in some Hydra lab somewhere, which means he doesn't have to sit here and take whatever is thrown his way.

Bucky opens his mouth, "Do... don't." that's not enough though. "Please don't touch me."

He feels tight all over in the wake of it, waiting for the hammer to fall.
