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?
 * 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!
