That's an interesting one to think about, and funny as hell.
I was watching that and thinking about what I'd do if I were there. I believe my first response after the jump would likely be to start talking to her, and possibly reach out to touch her. Level of 'freaked' would depend on my state of mind. Most of the time, I am fairly laid back but sometimes stuff hits me wrong and I can freak out with the best of them.
If she moved toward me, don't know what I'd do, probably back away.
