This was a very interesting ep IMHO. Some actual profiling was used and within the storyline of the episode it made sense. Mulder must be rubbing off on Scully, who showed some impressive prowess in the field.

Having said all that, i doubt Mulder would need to go all the way back to DC to use their special photographic unit since that software would likely be at most field offices; Detroit, Chicago, and Columbus would be a much better use of time.

Maybe not a nit but would the drugs needed for twilight sleep be available at the average pharmacy, especially a small town's?
