The FBI arrests a serial killer John Mostow, responsible for the killing of at least 7 men. Mostow claims he was possessed by an evil spirit, a fairly common claim among serial killers as Scully points out. With Mostow in custody however, other very similar attacks occur leading Mulder to think Mostow may be telling the truth. The agent in charge of the case, the renowned Bill Patterson, doesn't think much of Mulder or the kind of cases he deals in. As the killings continue however, the evidence not only points to Mulder's theory being correct but points to the killer. Written by

The producers originally planned to film the teaser sequence at a Catholic hospital, but the hospital was reluctant to affix a faux gargoyle to the building. Then the shot was relocated to Heritage Hall, a noted filming location and former post office in Vancouver. Some last minute scrambling was required when city workers tore up the sidewalk where the producers planned to film the scene. The construction crew reassured the show that the construction would be finished in time for filming. The work was finished two hours before shooting started. See more
When Mostow's cell shutter is opened, the light from the corridor is extremely bright, yet when Mulder and Scully enter the cell the light is less harsh.
