[This question cuts a little close to the quick for Tony's taste, but he started the whole thing.]
Captain America was sort of a thing in my house, growing up. With my father having helped Dr. Erskine with the project, and all. [And not just in his house, he doesn't say. It's one thing to know Cap is a living legend and quite another to admit it out loud.]
Our official meeting was me dropping in on a fight he was having with a man wearing a ridiculous antler helmet. [Come to think of it, they never really met in the sense of shaking hands and introductions. They were there to do a job, and Rogers didn't like Tony's way of doing it, and things just... went from there.]
