Summary: When Tony finds out he's pregnant, he immediately begins working with Bruce to figure out how to terminate it. But when Bruce lets slip to Steve about Tony's condition, things get complicated, quickly. Steve wants Tony to keep the child, but Tony isn't sure if his heart - literally and figuratively - can take it. Meanwhile, a plot is brewing in the background, threatening superhumans and trying to pit them against one another, all in the name of Registration. Is this related to Tony's pregnancy? (Yes.) And if so, should he really keep the child?

His blue eyes were two giant wells of sadness, and Tony wanted to yank the damn arc reactor out of his chest to try and replace the pain of seeing Steve like this with something more bearable. "Me, my genes: It's not this." Steve gestured down at himself. "You don't want my kid because it'll be like I was."
