"That you're the kind of guy used to getting what he wants. Usually without giving anything in return. And you're kind of insufferably smug. No, seriously, why do I like you?" Note the lack of past-tense, there. Freudian slip? Maybe. Or maybe half of the reason she's visibly annoyed with him (nothing remarkable and honestly nothing to be concerned with) is that her Magic Radar is telling her this one's okay, and she has, as of yet, little to no evidence as to why. Besides the fact that he hasn't axe murdered her yet.
