The truth is out there…on the CW? We can confirm that Mitch Pileggi — a.k.a. FBI Assistant Director Walter Skinner on The X-Files — will pop up as a guest star on Reaper. Once again, Pileggi assumes the role of an authority figure, this time playing a bad-ass cop whom Sam (Bret Harrison) encounters while tracking down a demon. The episode airs Nov. 13, a fact that even hardcore conspiracy theorists are not expected to dispute.
