Revealing Mistake: Look closely at the folders Mulder and Scully are examining. The three folders in front of Mulder have the numbers 10, 17, and 47 on them. These same folders appear on the shelves Scully is looking through. In addition, there doesn't seem to be any sense to the numbering at all. While it's hard enough to imagine the agents will find evidence of a saboteur in all the files in the first place, wouldn't this jumble make it even more difficult?
