Factual error: Scully makes a reference to an F.B.I. field office in Kansas City, however, no such office existed at the time of this episode. (00:13:10)
Factual error: The townspeople contracted Creutzfeldt-Jakob disease (CJD) from the bodies they consumed and it showed up in the brain tissue within a matter of weeks. However, this extremely rare disease takes several years to even be detectable. (00:18:55)
Other mistake: Unlike Mr Chaco, who has the brace clamped around his neck, Scully is clamped around the top of her head, which is a quite irrational way of executing a person, because the clamp does not serve as a stabilizer. In fact, in this arrangement, Scully is not fixed to the stand at all. (00:38:15)
Factual error: Mulder says that the events occur near I-10, however, I-10 is nearly 200 miles south of Arkansas's border in southern Louisiana.
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.
