"Shows what you know, kid," said John. "I don't like a damned thing."
Bucky laughed. "That's what Mr Kvaratskhelia said too," he said, by which he meant Zachariah, of course. John's brow twitched in irritation. This wasn't news, but he never did like the reminder that Bucky could be bothered to remember Zachariah's ridiculously long surname, and yet he was forever 'Mr John'.
