"The Host" has created quite a following within The X-Files fandom. Most of us love it, even when disgusted by him and whoa, is he a slimey one! We even had Dr. Joselyn Rojas tell us how many worms may have inspired Chris Carter to write us such a noteworthy one.
This episode still deals with Mulder and Scully's separation from the X-Files, but the introduction of two key elements: a new informant - Mr. X, who finds the reinstatement of the X-Files a necessity, and also Skinner's admission that while he may comprehend Mulder's objectives, he also takes orders from someone. The plot thickens!
