For now, at least, he keeps a close eye on Steve, admittedly not entirely sure what he'd do if the guy had a bad reaction, but definitely relieved when he doesn't.

Not so excited, though, when Steve looks at the shield like that. "Not in the shield, we're not," Bucky points out, glancing around for something else they might be able to use. Leaves?

God, he feels like a city boy more than ever right now. "At least during the war, we had canteens."
