This marks the introduction of the pencils in the ceiling in Mulder's office, a sign of Mulder's boredom without Scully. They would feature in various episodes throughout the show's run.
This episode was co-written by Stephen King and the action takes place in New England, where many of King's works actually take place.
The title of the book lying next to the phone in Scully's motel room reads "Affirmation for Women Who Do Too Much."
