Trivia, Notes, Quotes and Allusions


  • TRIVIA (3)

    • Continuity: Tom Baker's facial wounds return in this episode.

    • Revealing Mistakes: A shot of rocks falling is used twice - once after Unstoffe is shot, once after the cannon goes off.

    • During the making of this story, Tom Baker got into a fight with actor Paul Seed's dog in a pub. His swollen lip (where the dog bit him) is clearly visible in the next story.

      Interestingly, near the beginning of the next episode, the Doctor bangs his mouth against the TARDIS console when a landing goes awry, causing the ship to shudder. For the rest of the episode he is seen with a mark on his upper lip. This was most likely written in as an explanation for the mark.

  • QUOTES (11)

    • Garron: There you are! I've been looking for you everywhere. [ holding up the tracer ] You, err, dropped this.
      Romana: Into your hand, yes!

    • Garron: Now we should be looking for my invaluable young friend Unstoffe.
      The Doctor: Who's carrying a valuable piece of jethrik.
      Garron: What is property at such a time?

    • Unstoffe: You'd risk your life for me. Why?
      Binro: You wouldn't understand. For years, I was jeered at and derided. I began to doubt even myself. The you came along and you told me I was right. Just to know that for certain, Unstoffe, is worth a life, eh?

    • Romana: Garron? Garron, where are you?
      K-9: He has departed, Mistress.
      Romana: Well, that's obvious, but to where.
      K-9: To see a man about a dog.
      Romana: What?
      K-9: That was the information he imparted.
      Romana: Well, why didn't you tell me earlier?
      K-9: You did not ask, Mistress.

    • Garron: Unstoffe, my son?
      Unstoffe: What?
      Garron: I was going to make a touching speech, but my throat is too dry.

    • Garron: How did you manage to switch the jethrik for the thermite pack without the Graff noticing?
      The Doctor: Garron, I would have thought you'd have known that. Sleight of hand. I was trained by Maskelyne.
      Romana: Quite clever, really.
      The Doctor: I do dislike faint praise. It was astoundingly clever!

    • Garron: I was afraid he'd notice.
      Unstoffe: Notice? What?
      Garron: We haven't lost the jethrik. I switched it for a piece of ordinary stone. I did, look. He switched it back again! Oh, Unstoffe, is there nobody you can trust these days?

    • Romana: You nearly got us killed.
      The Doctor: If you call that being nearly killed, you haven't lived yet. Just stay with me and you'll get a lot nearer. You're a lot nearer right now.
      Romana: You've got an unconscious death wish.
      Garron: Don't bicker!
      The Doctor: Not bickering.
      Romana: Never bicker.

    • Unstoffe: Money isn't everything, Garron.
      Garron: Well, who wants everything? I'll settle for ninety percent.

    • Graff Vynda-K [ to the disguised Doctor ]: So you're the last of my guards, eh? The last of my Levithian Invincibles! All the rest are dead now. Even Sholakh. Were you with me on Skarne, soldier?
      The Doctor: No, sir.
      Graff Vynda-K So many battles. Skarne, Freitas Labyrinth. Crestus Minor. There was a fight! I remember Sholakh planting my standard in the very heart of the Krestan general! So many battles. So many years. But over now. All but one of us doomed to die, soldier. Thus has it been written."
      (Graff Vynda-K activates a bomb and hands it to Doctor, who clasps it to his chest.) There is no greater honour, soldier, than to surrender your life in the service of the Graff Vynda-K! All but one of us! Sholakh? Sholakh? Sholakh! To me! To me! Charge! Onwards! Onwards!

    • Garron: Well, I admit I had a great struggle with me conscience. Fortunately, I won.
