"I don't know that for certain, I'm not a tested super soldier so I'll just say I'm not one unless I'm proven wrong." He would have to see how the serum changed how good he was in a fight and if he was more useful than he was before, he'd call himself a super soldier.
"I'd be afraid to play tennis with Thor, even on a Wii. I've seen him throw Mjolnir, imagine how many pieces that poor controller would be in."

I'm gonna enjoy the quiet as long as I possibly can."

He had gotten a room below ground in the basement not to be distant, but because he found the silence there nice and because it was just a preference of his and had been for years.
