Wait, Robert Downey Jr. Could Be In Black Widow?

While not confirmed, in some ways this would actually make a lot of sense. Marvel has brilliantly started playing around with timelines, giving us stories that occurred earlier in the history of the MCU with Captain Marvel. At Comic-Con earlier this year, Marvel made it clear that Black Widow would be set between Captain America: Civil War and Avengers: Infinity War, giving the idea of this cameo some credence. What I like about this alleged info is that it would finally pinpoint more specifically when Black Widow is set.
