John should have a fanclub in the MCU
Just a little breather subplot for a bigger story: John discovers he has a fanclub; it's nothing huge, just a small group of people who get together once a month to talk about the day John saved them or someone close to them ("Everyone else was so focused on fighting Doom... but you didn't let my Mom die. Thank you."), or some veterans who empathize with his trauma struggles ("I saw that look in your eyes on the news. I had that look back in Desert Storm. But look at us: still standing."), and still others who just see a good guy trying his best and finding that an inspiration that moves them to try harder in their own life ("A lot of days... I just feel like I can't do anything good enough for anyone. And I think a lot about giving up. But, see, I got this poster of you on my wall man, from when you were Cap? And every morning I say to myself "If he can keep trying, so can I".").
And John gets to meet them.
