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.

Plot hole: The subject of the stakeout - the religious man dressed as a female prostitute to 'put the other prostitutes at ease' before trying to 'save' them - is shown when Scully is on the phone telling Mulder about it; the man has a very masculine face, a hairy stomach and is in no way convincing.
