Surprise, Nat & Steve, it’s a boy!
This is James Rogers, from Marvel’s Next Avengers: Heroes of Tomorrow. James comes from a post apocalyptic timeline where the Avengers lose against Ultron, most of them die and their kids - yep they have kids in this timeline - are taken by Tony Stark to his arctic fortress where he raises them in relative solitude and trains them to one day face and defeat Ultron.
Spoiler alert: James messed up, Ultron found them and chaos and I ensued. The kids eventually beat Ultron (with some help!) and they’ve been traveling the world since, fighting the remaining bits and trying to help rebuild things in general. James will be glad to see Torunn but he will have mixed feelings about being here. He’ll like a chance to get to know these versions of his parents, but he also feels the responsibility to be back home doing that hero shit.
