"You might not be able to do anything differently now," Thor says. "But you still have the chance to fix things when you return home."

Thor shifts one of his hands away from Tony's back and over to the side of his arm. He knew from the moment that Tony leveled the accusation that he was right: he was projecting. But Thor didn't want Tony making the same mistakes he did. He didn't want him to agonize over them the way he did. And while right now, it was clear that Tony was in pain because of it, it didn't always have to be that way; he could fix things between Steve and the others when he went back.

This wasn't permanent.
