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


 * How did Ashildr get a piercing when the Mire chip should have instantly healed the wound.
 * In Face The Raven it was stated that the Raven searches in space and time for its victims, so if Clara had gained a pulse wouldn't the Raven start looking for her again? And one more thing, how can a neuro thingy can be human compatible and would work for the Doctor too? I know the Time Lords invented it but the humans have another biology so if it works to humans it can't work for time lords or the other way round.
 * 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.
 * The General also seems to personally respect the Doctor quite a bit. He did also save the General, the High Council, and indeed every single one of them from destruction by the Daleks. He is more than just a war hero.
 * Also, based on what the General says after having gotten rid of her first male body, the Doctor appears to have done her a bit of a favour. She may not have been that upset about it. Consider that this person is a soldier who went from being an elderly man to a much younger person, better able to command troops; the General might well have seen it as a positive outcome on several levels.
 * 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.
 * There's also the point that she tends to keep notes about things that happen to her. She may have considered this a major event (and rightfully so) and just kept up with that journal entry.
 * Also, over billions of years she might have figured out a way to keep her memories intact over time. Maybe she has a computer chip in her head or altered the Mire tech in some way.
 * 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.
 * Captain Jack Harkness was just revived without control. It wasn't the plan to make him immortal, she just made him survive until he could tell the Doctor about the Master and help in New(x15) York.
 * 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
 * Additionally, it's not just an ordinary Mire medical kit - the Doctor modified it when he saved her life.
 * 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.
 * It could have been a figure of speech, or she was also speaking from the Doctor's perspective.
 * In the "long scale" mathematics system used in Britain, "billion" is the same as trillion. So there is no error here. See.
 * 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?
 * The Tenth Doctor also hated guns, the Time Lords, taking advantage of his victory in the Time War, etc. The Twelfth Doctor is much different psychologically; the Tenth Doctor was very emotional, so even though every incarnation is a separate persona, it was also a minor inconvenience for some.  I think it's mainly that the Tenth and Twelfth Doctors are different personas, so they have different perspectives.
 * To further that, he also wasn't going to let the man stay standing, he wouldn't "get out of the way". Also, the Doctor was willing to shoot the Master or Rassilon back in "The End of Time"; he only changed his mind when he realised the link wasn't either of them.
 * The Tenth Doctor is literally the only Doctor who made a big deal about regeneration. The only other doctor who got upset about regenerating was the second and that was because he was being forced to regenerate. It should be obvious that the Tenth Doctor's reaction is the exception to the reality of what regeneration is like for a Time Lord.
 * I think it's worth noting that the Eleventh Doctor dismissed the Tenth's attitude towards regeneration as "vanity issues".
 * Remember too that in this story the Doctor has really gone off the rails. He's prepared to risk the destruction of all time and space to save Clara. 'You've broken every rule you've ever lived by' says the Sisterhood of Karn. 'I've gone too far' he says at the end. So naturally he'll dismiss robbing a fellow time lord of a life as inconsequential. We really see the Doctor at his lowest. I found myself almost siding with the Time Lords, especially when he Doctor is told that all he had to do to escape the confession dial was admit what he knew of the hybrid.Great story, though I was a little disappointed that, having been reintroduced to the Matrix after three decades, it played no real role in the story. Similarly the sliders, scary as they were, didn't exactly do anything.
 * Fair points but I don't think it changes my initial comment about the Tenth Doctor much - he really had the most negative view of regeneration of any Doctor. The Doctor may have gone off the rails in this episode but the idea that regeneration isn't actually big deal for most Time Lords isn't necessarily him going to far.
 * You also have to think though that at that point, he knew this was his last regeneration. He knew that that was it. His last incarnation. Imagine how you might get when you're at that time of your life. At first, you really fear it, but then, once you're closer to it (Eleven, circa Time of the Doctor), you sort of just accept it. Ten was just suuuuuper scared is all.


 * Plus, given how the Time Lords are usually described when not in the Time War ("dusty, old politicians" as said in School Reunion), they may not typically see regeneration as vital to survival as the Doctor. One incarnation can live at least 1000+ years, once stated to be 10,000, before regenerating. Given the Doctor's current estimated age, he should barely be in his second body at most. He lives an incredibly dangerous life that necessitates having regenerations left, whereas living a normal lowkey life as a typical Time Lord, regenerating would be an inconvenience for than anything. Also, the Tenth Doctor still believed the Time Lords were gone, meaning he was probably in a panic on approaching his final body; as for the "new man" comments, it seems to be a general belief (2 being mad at his appearance changing, 9 saying goodbyes to Rose as if he was dying, the General believing her male incarnation had a bigger ego than her, etc.), but given the Tenth's vanity, it was much more pronounced. Finally, being a higher up authority on Gallifrey, the General would likely have access to more regeneration cycles.
 * Aside from the above valid points, do keep in mind that every Doctor has different attitudes towards things. The Twelfth Doctor, for example, is considerably more anti-military than others.


 * The Doctor said he was looking for the TARDIS in London after losing memory. So he just got to Nevada, then went to England, then again to Nevada? It seemed that he was going to the bar straight after waking up.
 * Not unless he stopped at a guitar shop along the way. There is nothing to indicate how long it's been. We also don't know what led him to that diner in the first place so presumably he received some sort of message indicating he might find the TARDIS there; he didn't just randomly show up and Clara and Ashildr didn't just wait till the Doctor's hitchhike ended before parking their TARDIS!Diner.


 * The Doctor says Clara's bodily processes have been time-locked. If so, how can she produce tears? Or drink lemonade?
 * Or talk, or move, or do anything, for that matter.Yes, I found the extraction thing a difficult concept. If Clara is extracted a moment before her death, surely her heart would be racing, not silent. And why not extract her at an earlier point in her timestream?
 * They extracted her because the Doctor claimed he needed to question her. Therefore, they needed her to move and talk. Maybe the extraction process is an inexact science, allowing for some bodily processes but not others. As to why extracted her at the moment of her death, my guess is they didn't want to risk messing up the timeline by sending her back with knowledge of Gallifrey and the Doctor's future. Plus they have access to the sum total of her knowledge at that moment.
 * Extracting her at the moment of her death was necessary to avoid a major paradox because the Doctor needed to have seen her die in order to arrange for her to be extracted later. Extracting her earlier in her time stream (even, say, before they entered trap street or a week earlier) would have been unacceptable. And even if the Doctor had this in mind, remember the whole thing was a bluff to trick the Time Lords into extracting her and they would never have allowed it.
