Scully had to chuckle softly at her own error. Of course. How like a professor to correct her. Her smile did freeze a little, though, when he said 'werewolf' - but then she thought, quickly. There had been the manitou. There was the matter of her own immortality. And the people here didn't seem - well - to be from quite the same places. She couldn't judge. Even if the lycanthropy of the individual he'd mentioned was some sort of naturally occurring condition, clearly, wherever he was from, a suppressant or treatment had been made. To try and question him would be a matter of semantics, at best.
So she shelved her skepticism for another day and said, "A werewolf. I hope you were successful?" She probably would have heard something about it if he hadn't been. From her, however brief, experiences with creatures of that type, they were dangerous if left unchecked.
