The Doctor[]

  • The Doctor tells Lilly that he has known many beekeepers in his time. He claims that Aristotle never stopped wittering on about bees whereas he was stuck at a tea party with Thomas Jefferson and he spoke about them at least.
  • Klein tells the Doctor that, with his intelligence, he would have been a great asset to the Nazi Party. The Doctor sarcastically remarks that it was "such a sweet thing to say."


  • The Doctor and Klein previously visited the crystal planes of Mendroxia, the floating ocean on Quinbrax Four, and the mercury swamps on Vulcan.


  • Through the TARDIS' telepathic circuits, Klein hears the Doctor speaking German in "a stuffy Prussian accent."
