The Host
Mulder and Skinner get off on the wrong foot when Mulder is assigned an usual case, however he sees it as some sort of punishment. All is not what it seems when the suspect turns out to be some sort of strange Chernobyl outcome parasite\human intent on killing anything that sets foot in the sewer. Scully stands by Mulder in the case, and the two of them learn of a friend they’ve made in the FBI. Who he is we do not know, but all he informs Mulder of is that reinstatement of the X-Files is undeniable. Skinner is happy with Mulder for now, but is loosing his temper fast.
