Other mistake: The landing plane is shown in a incorrect scale - it's too small compared to the sedans chasing Mulder and Scully. (00:32:30)
Other mistake: When examining the bag via X-ray at the airport, Mulder communicates to Scully that he sees three circular pieces inside, however only one circular piece is visible inside the superstructure. (00:31:20)
Continuity mistake: In the shot of the 6th Precinct police station, it has a California state flag flying out front. The episode took place in Massachusetts, at the Massachusetts Institute of Technology. (00:07:45)
Plot hole: Scully's statement that she was 23 when she wrote her senior thesis in college throws off her timeline of college, med school, residency, FBI Academy, Quantico teaching assignment for two years, and X-Files assignment at 28. Her undergraduate degree in Physics should have been completed when she was 20 or 21 to allow at least 4 or 5 years for her medical training. (00:41:35)
Deliberate mistake: When the unconscious, naked Asian doctor is removed from the warming tub, his hands are clasped over his crotch to protect his modesty, despite the fact that he shouldn't be able to do that, since he isn't conscious and his previously frozen limbs are now pliable and relaxed due to the heat.
Continuity mistake: We see Scully wearing pants while sitting on the couch, but when the real Mulder comes in, she jumps up and we see she's wearing a skirt. (00:38:35 - 00:41:25)
Factual error: The date stamp says that it is April 12 and Scully says that it is Sunday, but April 12, 1997 was a Saturday. (00:03:10)
Visible crew/equipment: When Scully asks Fox "Do you know what day it is?" the boom mic drops down at the top of the screen. (00:04:50)
Visible crew/equipment: As Fox is being led into the jail, when Scully says, "Mulder" the boom mic is at the top of the screen, while she's walking towards him. (00:20:30)
Continuity mistake: During and just after the Mulder's seizure, when Scully's face is shown, it is at the level of a standing person which suggests that both agents are standing, but in the next shot Mulder and Scully are crouching. (00:31:35)
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.
