Clyde Bruckman's Final Repose - S3-E4
Character mistake: Clyde Bruckman says that the Big Bopper won a coin toss that put him on the plane that crashed and killed him along with Buddy Holly and Ritchie Valens. The person who actually won the coin toss was Ritchie Valens.
Character mistake: Scully continually addresses the senior police officer as "Captain." But he wears sergeant's stripes. As a law enforcement officer continually dealing with other law enforcement officers, Scully is not likely to make this mistake. More likely a failure to match script with costume.
Character mistake: When Mulder and Scully are in the graveyard, the headstone says "Howard Patrick Graves", but the newspaper said his middle name was Thomas.
Character mistake: When Josepho meets Agent Scully, he recites to her the passage from the Bible that begins with the phrase: "Behold, a whirlwind came out of the north" Then he asks her if she knew that fragment from the Bible. She answers: "Ephesians." Unfortunately, she is wrong, because this fragment comes from Ezekiel 1:4. (00:30:30)
The Sixth Extinction (2) - S7-E1
Character mistake: When Kritschgau is testing Mulder's remote viewing capabilities, he tells Mulder that he is at about 5% accuracy. However, Mulder got at least two right and not enough time had passed for him to have had 40 opportunities, so his percentage of accuracy should be higher than five. (00:27:00 - 00:27:45)
Anasazi (1) - S2-E25
Character mistake: Mulder asks Scully about "the fourth commandment about obeying the Sabbath, the part when God made heaven and Earth " However, Scully as a Catholic should know that this is the third commandment for Catholics. This is also an indirect indication that Mulder was raised in Jewish religion. (00:09:25)
Character mistake: Scully gives a description that Eve is driving a Blue Carolla. However in the next scene, Eve is driving a Pontiac, not a Toyota. (00:28:00 - 00:28:51)
Nothing Important Happened Today (1) - S9-E1
Character mistake: When Agent Dogget is eating breakfast, he listens to the information in TV news about "the body of 38-year-old Carl Wormus." However, the obituary which Agent Reyes is reading later says that "Carl Wormus was found dead at the age of 45." (00:07:30)
Character mistake: While examining Agent Michel's body, the doctor says to Arthur Dales about "toxology report" instead of "toxicology report." Toxology is the study of archery. (00:26:50)
Character mistake: Vassily Peskov speaks Russian with a strong accent. This is because the actor who plays Peskov (Jan Rubes) was from former Czechoslovakia.
Musings of a Cigarette-Smoking Man - S4-E7
Character mistake: Ramón Mercader did not assassinate Leon Trotsky with an ice pick, as Frohike claims, but with an ice axe. (00:03:00)
Character mistake: Surprisingly, it took Scully quite a long time to realize that the tattoo on the victim's forearm is in Cyrillic lettering. (00:24:00)
Miracle Man - S1-E18
Character mistake: Scully says "She is dead" instead of performing cardiac massage, as any other doctor would do. (00:25:45)
Character mistake: Scully says that it was Teresa Nemman who was summoned into the woods tonight, while in fact it was Peggy Odell. (00:35:00)
Character mistake: Pusher says that he read in Scully's files that she had shot Mulder, although after Pusher's visit in the Computer Records Office Skinner says that Pusher checked only Mulder's files. (00:40:15)
The Sixth Extinction (2) - S7-E1
Character mistake: When Scully is reviewing part of the translation she has made of the alien artifact, there are four amino acids that she has written: Ademine, cytosine, thymine and guanine. Ademine is misspelled. It should be adenine. (00:23:10)
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.
