I love that, in spite of everything, Tony and Rhodey's relationship is still intact. Rhodey doesn't regret his choice in Civil War and somehow still manages to tease Tony. They were a beautiful parallel of Bucky and Steve, of what they were, what they would give up, and who they would become.
Well, then. I think my mind has been blown for the day! I recommend you read every word of this (it's worth it), even though it's pretty long, because it gives wonderful insight into the character of the Winter Soldier!
