Factual error: At the end of the episode, Tom is at a crossroads, theoretically in Iowa. However, the desert/scrub/mountain surroundings are scenery not found anywhere in Iowa.
Factual error: Tom's mother lives in Iowa, but the flowers/plants in her garden include types that could only live in places with warm/temperate weather all year round, which is decidedly not the case for Iowa.
Factual error: When Tom is locked up in an institution for the mentally ill, he is given a bed on a mixed gender ward/wing (both men and women). Wings and wards in mental institutions have not been mixed gender for more than 100 years - it is inconceivable that this practice would be existing in the 1990s in a large city in the USA.
Audio problem: The scene where Tom goes to his home, to be confronted by his wife, the dog, and another man holding a shotgun. The other man has just told Tom that either he walks away or he gets shot in the leg. There is then the sound of the dog growling for several seconds, but the dog's mouth/muzzle isn't moving, and it isn't growling.
Continuity mistake: When Tom initially breaks into his studio, the "Hidden Agenda" photograph has a plaque underneath it. When he returns later with Dr. Bellamy, the plaque has disappeared.
