"I'd like to, yeah." At least for a while. If he ever found someone of his own then he might move out but...until that happened he wanted to be with Tony and Pepper. Yawning, Steve shifted over to snuggle against Tony's side for a moment, taking what time he could to just rest to try and get up the strength to actually move to the bathroom.
