Trivia: If the story in this episode is to be believed, Scully is now completely immortal. Alfred Fellig couldn't die because he had bypassed death - his nurse died in his place. When Scully is all but dead and Fellig grabs death away from her and dies himself, this should leave Scully in the same position as Fellig was before he died - completely immortal.alargemango
Trivia: The shot of Tooms going down the chimney to reach his fourth victim was not done by any visual effects. A contortionist named Pepper actually squeezed inside, and then the sounds of bones cracking and snapping were added later. Confirmed by co-executive producer Robert Goodwin.
