Mind's Eye - S5-E16
Other mistake: Since the apartment was supposedly "turned inside out and upside down, " as Detective Pennock claims, it would be practically impossible that such an obvious place as the shaving blades container not be dug up thoroughly by the police. (00:12:15)
Mind's Eye - S5-E16
Continuity mistake: When the policeman passes the phone over to Marty, in the first shot from behind she holds it with two hands, while in the next frontal shot she grabs it with her left hand and then with the right hand. (00:13:20)
Mind's Eye - S5-E16
Visible crew/equipment: During the scene of Marty's interrogation there is some dark blue element behind Mulder when he is reflected in the mirror. However, in the frontal scene there is just a plain wall behind him. (00:24:00)
Mind's Eye - S5-E16
Continuity mistake: While talking through the jail glass, Marty's face is generally directed straight toward Mulder's face when reflected in the glass, but her head is twisted to the right when filmed from Mulder's side. (00:34:40)
Mind's Eye - S5-E16
Continuity mistake: At The End of this episode when Mulder is talking to Marty through her jail cell, the position of their hands change. In one shot, Mulder's hand is covering hers, and in the next, each of their hands are gripping the cell bars. This goes back and forth a few times. (00:43:00)
Mind's Eye - S5-E16
Other mistake: When Marty is being transferred and 'sees' herself because the killer is watching her, she should have seen herself viewed through a wire fence, as the killer was standing behind one.
Continuity mistake: If the Kernoffs were really devoted Catholics why would they have waited six years to have Dara baptised? (00:00:40)
Continuity mistake: When Dara walks toward the angel, there is only one car, parked on the right side of the street, but when her father approaches her, there is another car parked on the opposite side of the street. (00:02:50)
Revealing mistake: During the autopsy, right after Scully has the vision of her daughter, the body of Paula Koklos can be seen to move (watch her hands and neck). (00:24:05)
Other mistake: In the police station, Scully looks twice at a photograph of one of the dead kneeling girls, whose eyes should be burned out in the photograph, but they are normal.
The Pine Bluff Variant - S5-E18
Continuity mistake: When the bank manager goes to open the door for the brinks truck containing the robbers, the clock on the wall reads 9:45. When the robbers are taking him back to the vault, a couple of shots of the skull-masked robber shows the clock reading about 9:43.
The Pine Bluff Variant - S5-E18
Other mistake: On the information text at The Beginning of the scene telling the viewers where the scene is taking place, it is written as the "First Sovereign Bank of Pennslyvania" in "Harrisburg, Pennslyvania", instead of Pennsylvania, misspelling the name of the state both times.
Other mistake: When Mulder is on his knees in the cafeteria talking to the gunman, there are several shots where you can see the sides of his jacket hanging wide open because of his raised arms, which would make the gun on his belt easily visible to the gunman as he talks to him, but he somehow doesn't see it until he goes to take Mulder's phone.
Continuity mistake: When we see the Russian guy get shot and he falls out of his chair, he knocks the chessboard off the table. But when Jeffrey Spender shows his team the tape, the guy hits the board so that it spins around, instead of falling off completely. (00:02:40 - 00:07:55)
Continuity mistake: The chessboard was knocked down by the falling Russian, however in the next shot it is still on the table. (00:02:55)
Other mistake: In order to leave such bloody footprints, CSM must have stepped into the puddle of blood. It is impossible because the guy shot by CSM could not bleed so much blood in such short time, not mentioning that CSM must have intentionally stepped into it. (00:05:20)
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.
