Hi? That was all she had to say? He was surprised, thoroughly surprised he didn't get a snarky comment the second she'd opened the door. But he was very grateful for it because it would have just fed into his own snark, and it'd have quickly dissipated into something neither of them wanted right now.
"Hey," he said, hands dug deep into his jeans pocket. "So, you decided that for some reason this place is better than good ol' Stark Mansion of Awesome? I think Jarvis and Salt are lonely without you." He wasn't admitting to the fact that he was genuinely freaked out when she hadn't been there when he woke up.
"Jarvis told me you, uh, saw it." And there was a slightly embarrassed twinge of pink creeping into his cheeks. "Can I come in and commence with persuading you to move back?"
