That is not the direction his body was expecting to move in, so he ends up stumbling in to her more than anything. He has no idea where his hands have ended up after he latches on to her to steady himself, but he can only hope it's not some place hideous. Or he would hope that, if he had the ability to notice or care.

He can only focus on one thing at a time, and her demand is apparently It right now. "Um, really?" That sure is an unattractive face he makes. "This ain't an excuse to get close and snatch that wallet back, is it?" It's a good plan. She'd have the keys and the money... "'S what I'd do," he admits with a nod. "But it's a dick move. Don't be a dick. You can't be a pretty dick."

Just kill him, Kathryn. Do the world a favor.
