Revealing: When Scully enters the F.B.I. Building after returning from Africa, she isn't wearing her badge. She'd need it to walk around without being stopped by security.

Continuity: When Scully is talking to Skinner in Mulder's empty hospital room, her cross necklace is off to the left. Then, when she says, "Sir." it's almost centered. And no, this was not caused by her turning around a minute or so before she said it.

Continuity: The dates on the academic discipline and progress forms for Max are not in accord with the order of the episode, coming after the "Millennium" episode. Supposedly the changes in his behavior and grades started a few months before, but the reports are from a few years ago.

Factual error: Mulder calls the dust in Maleeni's van "lycopodium powder" that the Los Angeles Police Department used to collect fingerprints, but the real LAPD uses latent print powder not lycopodium.

Visible crew/equipment: A mic boom operator is visible on the left hand side of the screen wearing a white t-shirt, beige shorts, and sneakers. He's carrying the boom mic and following Mulder and Scully. You can see him when Mulder and Scully arrive at the "Church of God with Signs and Wonders" for the first time...when Mulder delivers the line "That's funny, I knew a couple Catholic schoolgirls who were experts at it."

Factual error: When Reverend O'Connor is reading from the Book of Revelations, his Bible is flipped open towards the front. Revelations is the last chapter in the New Testament, so his Bible should have been open towards the back.

Plot hole: When Scully enters the game room after the game has shut off and the Lone Gunman are there but Mulder is missing. She is told that the only way in/out is from the door she came in. Later we find out that the bay that players use to enter the game is at the other end of the room and not conected to the door Scully used. So how did Mulder and Scully enter the game from the bay when the game was running?

Visible crew/equipment: In the scene where Scully is performing the autopsy on Micah Hoffman, you can see a shadow of someone moving across the wall behind her.

Plot hole: In this episode, Mulder and Scully are watching a film about them that was shot sixteen months ago. But that would have been sometime in late 1998, when Mulder and Scully were not on the X-Files. But yet they're in Skinner's office at the beginning. If they had shot the film in consistency with the current timeline, (2000) then the film would have been shown in late 2001. But in that time, Mulder was missing and Scully had a newborn. if anything, she would have seen the movie with Doggett. Somebody didn't plan ahead...

Continuity: Scully tells Burt that Betty lived in a blue house and later tells Mulder that she found Lulu, who lived in a pink house. Betty actually lived in the pink house and Lulu lived in the blue one.

Continuity: In this episode, both Mulder and Scully say that the last time they were in Oregon was 7 years ago. A previous episode this season dealt with the millennium, so we know this episode took place in 2000. So seven years ago would be 1993, the year the show first aired. But in the Pilot episode, the corner of the screen reads their location in Oregon and March 7, 1992. 8 years ago.
