Prelude

Jack Carter Stark is Tony's son that he didn't know he had until the kid was brought in by a social worker. he may be as smart as Howard and Tony, but that suited him just fine.

Then he meets the Winter Solider- James Buchanan Barnes.

A/N: So, my first Son of Stark thing. I've always seen Daughter of Stark and haven't really seen the former. Yes, Jacka-boy is gay and he ends up being interested in Bucky. Why? Why not?
PS: Not sure if I'm gonna go through ALL the IM and avengers films starting with Ironman or what. It's all up to you guys. If you want me to, I can try. If you want me to start with TWS or CW, maybe I can, we'll see.
