yesyesyesyes to the time traveling fic!! Sounds awesome! Would be great to explore the period's homophobia and the Depression and Steve's poor health from Tony's POW. Like, you read history textbooks but until you personally experiance it...
Yes to all of this.
The fic could be about fifty shades of super interesting as far as social dynamics go and Tony struggling with knowing what’s going to happen to the guys and then (maybe) being there to see it. It would be interesting to rewrite a lot of CATFA with Tony in the background
