"And you can't tell me anything about it or else you'd have to kill me?" Bucky asks without any seriousness. He's sure that there's plenty about it that's classified and extremely need to know, and if anyone could kill him it might be her, especially if she tried while he was driving and not expecting it, but... well, maybe that's what makes it funny?

Or maybe his sense of humor is questionable these days.

"Are you going to be gone long?"
