The poor man has good instincts. Most people should be concerned when Mab shows an interest so his instincts aren't leading him wrong. But Mab doesn't go around making it clear that she is dangerous. She's just always a little off. She hasn't spent enough time among humans to fit in easily, she doesn't have enough expression, her mannerisms are older. She may have finally discovered google no thanks to purchasing a horribly outdated phone so she does know about things like paintball. Mostly though, she's just a little amused to see a human so affected by the hunt that he looks a little like he'd enjoy grabbing and throttling the duck that circles warily farther out on the water now.

His insistence on more clarification than book knowledge does change her expression though. Rudeness, trying to force an answer out of her. Her lips thin in irritation. The fae do not like being cornered into answers. So she answers without giving him the answer he obviously wants. "Because I have felt many of the same urges." And that is the truth. The fae who join the hunt have a heightened bloodlust during the hunt and it seeps over even when they're not actively chasing down their quarry. It explains why she might have looked some things up. "Surely curiosity has driven you to find answers before?" And carefully redirecting questions meant she could mislead all she needed to.
