Dean watches her approach, tensing for something, and then it turns out it was good he did because they're hugging, and... oh. Okay. He doesn't quite have time to react before she's pulling away, and now he definitely looks confused. He'd been ready to just assume she hated him because he was an ass and/or because he left.

"You mean if I need anyone to teach me how to make awesome faces?" is his comeback because he doesn't know what else to say or what to think of her.
