Okay, that's...a little strange. Not the strangest.

"You know me?" It's not suspicious but curious, and he stays where he is for right now. One hand lifts, gently beckons the young man out. It's alright. Whatever he's afraid of, whatever has him cowering behind corners, it's not him. And he means him no harm.

Is that...ice? Maybe it's the cold. People get a little funny if left alone in the cold too long. Get a little dead, if left too long, but he doesn't think there's any danger of that just yet.
