This thread is fascinating to me because usually this com comes down entirely on the side of Steve and says Tony was completely unreasonable. I actually think both acted in ways that made sense. I get why Steve wouldn't tell Tony because loyalty is Steve's highest value, and Bucky comes first always. And I get why Tony would be pissed because it was his parents, and he was watching the murder.

I don't agree that they can't make up, though. I think that fighting side by side again could allow them the opportunity to make up. Even at the end of Civil War, we see that they both have a level of understanding of each other. They aren't complete enemies, and they know it. So I think they could be friends again.
