"Fox Mulder, the nutty professor," he says dryly. He could teach psychology as effectively as she could medicine, he suspects - which is to say, well, but he probably couldn't justify it to any school looking to hire him. Maybe at a community college, but in his heart of hearts, he'd feel like he was slumming, regardless of whether it was actually true. "We could both be teachers in our old age, Scully."

And, some part of him thinks, they could be bored out of their minds. He tries to think back to anything that might come close to teaching: younger agents trailing behind him, trying to build alliances or friendships, and he, closing himself off to them at every turn. "But I'd lack the pedagogy. I've never taught anyone."
