He really has no clue what to make of her yet. LOL. He has a vague impression of her as cool and in control, which he kind of likes, but that puts him in the position of being the one that has to be forward, and he's not good at being forward.

She sort of puts him off balance and I think as they get to know each other better they'll settle into a more consistent dynamic. I think Wanda could really take his tendency toward bitter sarcasm and return it, and he tends to have awesome CR with those kinds of people.
