Theory:Doctor Who television discontinuity and plot holes/Extremis


 * Why didn't the TARDIS translate the Pope for Bill when he showed up in her flat?
 * Perhaps we are seeing him from her friends' point of view; as we are not yet fully understood as to why the Pope is present?
 * Doesn't Angelo have to translate for the Pope later on, though?
 * Perhaps the Monks are unaware of the TARDIS's translation circuit and so it was not part of their simulation?


 * How could River have given Nardole the diary to look after the Doctor when after Darillium River has it in the library?
 * We don't know that River gave Nardole the diary directly. The Doctor and/or Nardole could have retrieved it from the library shortly after the Tenth Doctor and Donna left. Or maybe Nardole gives it back to her after this.


 * So, it's Missy in the vault. The Doctor agreed to guard her for 1000 years, to keep her out of trouble. Isn't time relative?
 * What do you mean?
 * From what I understand, Missy has been imprisoned for a crime, but once the sentence is over, she could easily go back in time and make her incarcerators pay for her imprisonment! The punishment doesn't matter, she can still get her revenge. Time is relative!


 * Who is the Benedict IX referred to? The historical Benedict IX was of course not a woman. He was in fact one of the youngest and licentious popes in history. He was pope three times, on one occasion selling the papacy for money.
 * I think it is a Moffat twist. It could be a woman, and it might end up being a woman in a future episode!
