Theory:Doctor Who television discontinuity and plot holes/Hell Bent


 * The Doctor's reasoning for up and deciding to part ways with Clara seems flimsy. It's supposedly because of what the fear of losing her did to him, but if she's essentially immortal until she goes back to the raven, then presumably they could travel for the rest of time and he would never have that fear again. And it's not as if the web of time would be damaged at all, since we're led to believe that Clara and Ashildir can travel about with no consequences. So, what was standing in their way really?
 * I think it's largely due to Ashildir's theory that the Hybrid was the combination of the Doctor and Clara. If they continued down the path they were on, the Doctor would only become more ruthless and would end up fulfilling the prophecy. So he came to the conclusion that it would be best if they separated.
 * Not necessarily a plot hole, but the Time Lords put up with a lot from the Doctor in this episode. Respect for a war hero is one thing, but given how ruthless we've seen the Time Lords be in the past, it's hard to believe that the general would just let the Doctor shoot him/her and then just stay back as he monkeys around in the Cloister.
 * Considering the general know not only of the doctor exploit during the war, but may know about the doctor taking care of Omega (Twice), Goth and of course valeyard spectacle. He may have decided he rather risk regeneration then the doctor wrath. plus compare to other timelord who were killed by teere own weapons and never regenerated i say he/she got off easy.
 * How did Ashildr/Me tell the Doctor "Clara died billions of years ago" if she has a finite memory? In "Face the Raven", she said something along the lines of "immortal body, finite memory". So how did she remember Clara dying?
 * Its stated during the scene that she's the one keeping together the small pocket of universe left so she has somewhere to live, so its completely possible she could've done something with her memory.
 * She just didn't forget that. A finite memory doesn't mean she forgets everything. In The Woman Who Lived we learn that she forgot her name and her village, but she still remembered the Doctor.
 * How can Ashildr live until the end of the universe? I mean, really? Even Captain Jack Harkness, who was immortalised by Bad Wolf the almost-all-powerful-entity, faced death after living so much time. How can simple medical circuit make someone immortal by that time? After all, where are the Mires? They are the ones who invented the magical immortal circuit.
 * She lives because she created a Reality Bubble where she can live and watch the universe dying, the other immortals are all dead because of the end of the universe
 * Ashildr claims to be at the end of the universe but then says that Clara died billions of years ago, not trillions as we were led to believe back in "Utopia", where the end of time was stated as being the year 100 trillion. To further this, The General also states that Clara has been dead for 4.5 billion years, "half the life of the universe". That's means the universe lives for 9 billion years, most certainly not 100 trillion. This is most certainly a discontinuity?
 * It was just a figure of speech. He didn't mean half the life of the universe, he was just talking about a long time
 * What about Ashildr's claim of Clara dying billions of years ago?
 * There are many billions in a trillion, so it is correct. She could've said millions and it would still have been correct. Not very accurate, but correct.
 * It could also be that the Time Lords were speaking from the Doctor's perspective of time. He was transported straight after Clara's death into the Confession Dial, where he spent over 4 billion years, and then breaks free onto Gallifrey. Ashildr's claim of billions of years? Hard to say.
 * The Tenth Doctor made a huge fuss over regenerating, to the point where he claimed that it was essentially another man walking away with his memories... yet Twelve dismisses regeneration as 'man-flu'? Huh?
