Prompt: Steve was found earlier, where Tony is only eight and grows a crush on Steve and childishly competes with Howard for Steve's attention.
(I went in a bit of a different direction with this one. It deals more with Tony fighting for Howard’s attention and feeling like second best when it comes to Captain America. Steve is living at the Stark’s mansion and is still adjusting to the changes in the world.
My heart breaks for young Tony. All that little boy ever wanted was a father. Crazy to think that Steve would have been perfect for that role if he had been found earlier. How different would have Tony turned out?)
