I happen to be attending Comic-Con in Portland this weekend and ended up staying at the same hotel most of the celebrities are staying at. I ran into Sebastian Stan last night outside the the hotel doors, just hanging out on the street. Bucky was drunk off his ass. Seriously. He was even dancing in the lobby. It was great. I asked him what happens during Infinity War, and even as blitzed as he was, wouldn't tell me anything lol. He was super nice, posing for pictures, but would not give up any spoilers. Just thought it was funny.
