That was Tony's cue. He gripped his own hands tighter, wincing slightly against the chill and squinting toward the door, not terribly inviting but at least a sure way back to the warmth of his bed. It didn't seem like Felwinter really felt the cold at all. With a last, lingering smile his way, a kind of apology for the invasion, Tony rolled up to his feet, then offered a hand to help him up to follow. No reason to stick around here alone, even if he didn't really notice that he was freezing.
