Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.

to be added



  • River uses a sonic pen torch.
  • The Master entered his tomb on Cheska Minor, but woke up on Cheska Major.
  • The Master possesses an Obsidian Mirror.
  • River compares the Master's style to Moriarty.
  • The Master asks, "Who was it said 'Humans should never invite their ancestors round for dinner?'" This both a reference to The Hitchhiker's Guide to the Galaxy and its author, the late Douglas Adams who both wrote and script-edited episodes of the classic series. This is also asked by the Seventh Doctor in the Season 26 story Ghost Light.
