Who says Black Widow was brainwashed? I got the impression that she did that stuff of her own free will. She had a specific skill set and she didn't care who used it for what.

If Bucky comes back I want it to be in the third one. Let's explore Steve's loneliness in the modern times first. If Bucky showed up in the second movie I'd just want him to get killed by the end again if only to cement Rogers as the only one of his kind out there. Hell, the only person besides Cap I'd like to see make it to the modern day, really, is the Red Skull just to drive home that the only person like him out there is a maniac.
