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.
Trivia: In this episode, if the facts are followed, Scully would live forever because Fennig saw Death instead of her. In the earlier episode "Clyde Bruckman's Final Repose" (the man who can tell when people are going to die), she asks when she is going to die. He says 'you don't.' Maybe Scully really is intended to live forever.
