(Fox) Mulder learned his learned behavior by being raised by particular people in a particular time and place, though. If Samantha was raised in that environment in his stead, she'd have some mannerisms in common with him.

I admit this is a short story and Samantha's barely more than an outline of a character here (deliberately, I assume). She's more of a way to make a point than an actual developed person.

I don't hate "smirked", used in moderation. I am pretty sensitive to eyebrow "waggling" (ugh, I don't even like writing the word).
