Notes & Trivia Edit

  • The events of this episode take place on Stardate 3018.2 in the year 2267.
  • Writer D.C. Fontana also had a hand in writing this episode, along with Robert Bloch, but was uncredited for her participation in this episode.
  • The transporter chief's name is John Kyle. He is identified only as transporter chief in this episode.
  • This is the first and only appearance of Crewman Jackson. Jackson serves as the "redshirt" of this episode.

Allusions Edit

  • Trick or Treating is an Earth tradition associated with Halloween. On October 31st, usually at night, children dress up in costume and go from house to house exclaiming "Trick or Treat", in the hopes of receiving candy as a treat.
  • Satan is a title associated with the Devil in the Christian faith. He is also known as Lucifer Morningstar. A very bad boy, he is often presented as the first of God's fallen angels, who becomes the father of evil across the world and resides in Hell.
  • In European folklore, cats are often viewed as being a witch's familiar. They may, as Spock asserts, be a demon in feline form, or they may be regular animals that are mystically attuned to the witch that it serves, who may use the cats as their eyes and ears.

Quotes Edit

  • Leonard McCoy: Three witches... what appears to be a castle, and a black cat.
  • James T. Kirk: If we weren't missing two officers and a third one dead, I'd say someone was playing an elaborate trick-or-treat on us.
  • Mister Spock: 'Trick-or-treat', Captain?
  • James T. Kirk: Yes, Mr. Spock... You'd be a natural. I'll explain it to you one day.


  • James T. Kirk: Bones... Doc? [sees a skeleton next to 'Bones', which is, like them, chained to the wall]
  • Leonard McCoy: You were saying something about trick or treat...


  • Spock: Don't let her touch your wand, Captain.


  • Spock: There are ancient Earth legends about wizards and their familiars.
  • Leonard McCoy: Familiars?
  • Spock: Demons in animal form sent by Satan to serve the wizard.
  • James T. Kirk: Superstition.
  • Spock: I do not create the legend, Captain. I merely report it.
