Well, that was just too limited an interaction in a controlled environment to draw any solid conclusions.
And don't bother too much about her Sharon Stone in Basic Instinct (with panties) moment.

She was either unaware or she was exactly aware of the effects of that gesture. Makes her either a fool or a temptress. Not the best possibilities.
For now, just start establishing a good rapport with her and a comfort level should be established. Talk to her, but do not show too much interest.
Good luck.
