I found it interesting that the episode painted Tony as such a staunch opponent of superhero registration, the opposite of his position in Civil War
. I was kind of expecting something to happen here that would change his mind, but he was still against it at the end. Maybe that's because Cap being a Skrull impostor pre-empts his role in the CW story.
I've forgotten what happened to Nick Fury in season 1 that led to Maria Hill taking over SHIELD.
