This occurred to me the other day while rewatching Endgame - would anyone else be interested in a telling of what Steve did between the 5 years between the snap and the beginning of that movie? IDK, that support group scene was one of my favorite scenes. It just really showed what a big heart and the kind of compassion and empathy the character has.
Also, 5 years is a goldmine of stuff draw from. So much unexplored territory there (I could see this being written by Mark Waid, btw. He's really the only choice for it).
