We've had some cases relating to vampirism. [One of which ended with a fire, but the other... Mulder recalls with some amount of frustration, still.] The most notable involved an entire town of vampires, with one standout citizen among them who went around murdering a couple of tourists. A very real vampire, who'd just happened to be in the possession of a fake set of fangs.

So this slayer deal... are there at least special powers associated with being chosen? [He at least in theory could guess how it might work.]
