Steve does a double take because oh yeah getting comfortable is a thing? He moves to sit down to get his shoes off properly. He appreciates the domestic. It doesn't come easy to him still. He'll get it eventually if there is such a thing in their future.

Steve looks up briefly. "Oh you know; one's a pleasure and the other one is being a pain in the ass." Guess which is which. Go ahead. Steve moves to unzip his jacket once his shoes are off. "Tony doesn't want to take it easy."

He tries not to feel self-conscious that Tony's actually coming up and will even more soon. It's clear Steve is being troubled by something even if he's determined to simply enjoy being back here a little longer. It is comfortable here; it's always comfortable with Sam. It's little wonder he doesn't want to share this so readily.
