Director: David Nutter
With Scully still missing and no one to trust, Mulder is forced to immerse himself in his work on the recently reopened X-files. Mulder opens an X-files case (No. 73317) on Scully's abduction, before being contacted by the LAPD, who are investigating a murder where the victim was drained of his blood.
Mulder recognises it as the work of a trio of serial killers called the 'Unholy Trinity', who he has been following for over a year. They previously struck six times in Oregon and Tennessee. They have a fetish for drinking the blood of their victims. The LAPD busy with a raging forest fire are more than happy to hand the case over to Mulder. Mulder rings around the local blood banks to see if any have recently taken on new employees. A ploy which pays off as he catches one of the killers John drinking blood in the basement of the Hollywood Blood Bank. John who calls himself 'The Son' claims he ingests blood because he is a vampire who can not die, but Mulder believes John is delusional. John is placed in a cell for the night but when the sun rises in the morning he is burnt to death, much to Mulder's surprise. During the autopsy on John's body, a stamp is discovered on his hand that leads Mulder to the Club Tepes.
At the club Mulder meets a vampire fetishist called Kristen. She knows John, they used to be in to blood sports together but then it all turned unnatural. Now he is dead she fears for her safety. Mulder has trouble determining whether Kristen is a criminal or a victim.
According to David Duchovny, in "Secrets of the X-Files", Gillian Anderson missed the past 3 episodes in this season, although it was cleverly filmed to appear that she only missed this one.
'Club Tepes' is named after Vlad 'The Impaler' Tepes, the real-life inspiration behind Bram Stoker's Dracula.
Mulder wears Scully's gold cross necklace throughout this episode after Mrs Scully gave it back to him in "Ascension".
