Howard and Peggy
"Well, I didn't mean Biblically." And he just wouldn't be Howard Stark if he let that opportunity pass him by. "But hey, if you ever wanted to change that..." He trusted Peggy to know he wasn't serious about that last bit. Well. Not seriously serious. She was a beautiful woman and he wouldn't kick her out of bed for eating crackers, but he valued her for more than just a knock-out figure and a pretty face. He wouldn't risk his relationship with her for a tumble or two, and with the two of them, that would be all it would amount to. He was too him and she was too her.
"I can safely say that I don't plan on making messes, Peggy. Messes just like to happen to me."
