Visible crew/equipment: When Mulder and Scully enter the abandoned mine through a doorway, the viewer can see at right in the distance a number of people sitting on a wall, and one crouching in front of the wall with what looks like a dog. They are sitting still, but there is still movement there. (00:16:00)

Triangle - S6-E3

Skinner: Use your head Scully. It'll save your ass.
Scully: Save your own ass, sir. You'll save your head along with it.

Trivia: Scully's father, Scully's older brother, and the man Mulder thought was his biological father were both named William. (The father who raised Mulder went by "Bill, " as did Scully's brother.) Mulder's actual biological father, Cancer Man, was played by William B Davis (who also goes by "Bill"). Scully and Mulder's son was also named William (before being adopted and having his name changed to Jackson).

Show generally

Question: In a vast majority of the episodes, whenever Mulder and Scully investigate some mysterious or paranormal phenomenon, Mulder believes that some unknown force is responsible but Scully always has a rational explanation for what is happening. In other episodes, when Scully herself is caught up in something mysterious, she is the believer but Mulder is the skeptic. In those episodes, why would Mulder be skeptical about an unexplained phenomenon considering that he a was witness to his own sisters abduction and he saw many strange things that defied explanation while working for the F.B.I.?
