He's not wrong there. If course Steve would've been mad - but at the Admiral. Not at Bucky. Or whatever he wants to be called.

Because, "Easy for them. For us. Not for you." Steve glances away, eyes focusing on a blank part of the sleek metal wall for a moment. "I could try harder. If you really want to stick with Asset." He knows they've been over it, but, "If you just let me call you Bucky because it seems... easier than telling me not to, then that's dumb. I - I'm your best friend. Or, at least, you're mine. I can be uncomfortable for the sake of your comfort. And I wouldn't be mad at you."
