Visible crew/equipment: While Fox is fighting the agent in the underground garage you see a crew person on the right side of screen for a split second. (00:38:55)
Continuity mistake: In the pre-credits sequence when the gunman is shot by the police officer, he initially clutches a wound on his right side. When he is shown lying down, the bullet wound is higher up and on his left side.
Other mistake: When Mulder and X are standing outside the Mulders' summer house, we hear that it is raining, but there is no sign of rain on neither of them. (00:17:50)
Answer: As he stated many times throughout the series, Mulder needed Scully to be sober and skeptical. Whenever Scully's skepticism wavered and she started questioning her own rationality, Mulder would try to restore her sense of skepticism, because he needed her to be clear-thinking.
