Trivia / Star Trek: Voyager S5 E17: "Course: Oblivion"

• Acting for Two: The entire cast portray the duplicate versions of themselves for almost the entire episode, with only the real Janeway, Chakotay, Tom, Harry, and Tuvok appearing at the end.
• The Cast Showoff: The return of Harry and the Kimtones.
• What Could Have Been: The follow-up to "Demon" was originally supposed to be even darker. It would open with Voyager triumphantly arriving at Earth. After fireworks and homecomings, Janeway has a tearful reunion with her (now ex-)fiancé Mark, and then suddenly snaps his neck; end of teaser. The writer also had an image in mind of a thousand duplicate Voyagers attacking Earth.
