Director: Bill Graham
Special Agent Fox Mulder of the violent crimes division visits a former FBI agent, Arthur Dales about as unsolved case from the 1950's involving Edward Skur as a suspect in a series of killings where the victims had their internal organs removed. Dales is reluctant to talk, until Mulder tells him his name is Mulder, Dales shows recognition of the name. Dales explains how back in the 1952 he and his partner arrested Skur as a suspected communist, that night he received a call from his partner saying that Skur had hung himself in jail.
Later Dales went to the Skur residence to break the news to Skur's wife, however when he got there Dales saw Skur walking down the street and gave chase but after a short scuffle Skur escaped. Dales was then approached by Mulder's father Bill, who explained that Skur was not a communist, he worked for the state department. His arrest and faked death was a cover up by the government, who tricked Skur in to having an operation called xenotransplantation, the grafting of a species into a human body. As the case is re-classified as an X-file, Mulder's father tells Dales the government is trying to cover it up, but the truth must come out.
The character of Arthur Dales would return a few times during the show's 6th season.
In the scene where Dales is being interviewed by Cohn, Cohn's assistant stands at the back of the office and silently observes. He stands in a similar pose and behaves in a similar manner to that of the Cigarette Smoking Man during Scully's initial interview in the pilot episode. The assistant, who is never named in dialogue or in the credits, is definitely an associate of Bill Mulder at the time. Despite the fact that he was not seen smoking in this episode, is it possible that Cohn's assistant was in fact the CSM?
David Fredericks reprises his role as J. Edgar Hoover from "Musings of a Cigarette-Smoking Man".
David can be seen wearing his actual wedding ring which is never explained in the series whether he was, as Mulder, ever married or not. See also ''Unusual Suspects'' where he also wears his ring. He seems to be making a point in both episodes to show his ring.
Dorothy Bahnsen: It's in an X-file.
Dales: An X-file?
Dorothy Bahnsen: Yes. Unsolved cases. I file them under "X".
Dales: Why don't you file them under "U" for "unsolved"?
Dorothy Bahnsen: That's what I did until I ran out of room. There's plenty of room in the "Xs".
Dales: Who decides when a case gets an "X"?
Dorothy Bahnsen: The Director's office. It's...It's kind of a dead end. No one's supposed to see them but it makes for interesting reading.
Dales: Do you know what an... X-File is?
Mulder: It's uh... yeah, it's an unsolved case.
Dales: No. It's a case that's been designated... unsolved.
