[He nods. The first part, at least, sounds familiar.] Yeah, I had plenty of heart troubles, before and after. I remember being pretty sick. [Which, you know, stands out from the times that he was just "normal" sick.]

And I wanted to go right after Pearl Harbor, too. I even got Bucky to wait around and try to train me a little first, but... [He shrugs a little helplessly.] 4F.

[He nods, though, looking a mix between relieved and sheepish.] Yeah. As far as I can tell, the serum fixed everything. I can't even get sick, now. [A little laugh, even if it's the tiniest bit sad.] Guess I'd make a great medic.

What changed your folks' minds? Or were you just sick of sitting around?
