Theory:Doctor Who television discontinuity and plot holes/Heaven Sent


 * How does the Doctor end up in the Confessional Dial?
 * The Doctor paints the portrait of Clara, yet when the castle is reset, the painting is complete. Surely, after a reset, the canvas would be blank?
 * In the following episode, Hell Bent, Clara mentions that the Doctor's eyes show he hasn't seen her in a long, long time. But, if the doctor killed each copy and was regenerated anew through the teleporter, only having lived for about a week or so each time, doesn't that mean that the Doctor last saw Clara a week ago in his memory?
 * No, because the episode establishes that once the Doctor makes the connection to the message "BIRD" all the memories of having repeatedly done this over and over come flooding back. Even though physically the Doctor of "Hell Bent" may only be a week or so older, mentally he feels all 4.5 billion years. Considering how poorly he's taking things at the 7,000-year mark, his clear insanity in the following episode becomes more understandable considering his likely state of mind at the 4.5-billion yer mark.
 * Yes, because the Doctor himself realises that each new version is a copy. With no new memories. Perhaps, at some point the Doctor realises he has repeated this over and over, but its a different version, who does not age!


 * Can somebody explain exactly what the Confession Dial actually was and how it works.
 * A general explanation is given in the next episode. It's also indicated that the Time Lords altered the normal behaviour of it here, in order to find out more about the Hybrid.
 * It's also evident that the dial utilizes some of the same "bigger on the inside" tech as the TARDIS.
 * The Confessional Dial seems a rather odd thing to create. Who would want to torture a weakened Timelord whilst in their final incarnation, just so they can upload their concious to the Matrix?


 * We see that the Doctor has been repeating for 7000 years, so how come the wall he punches has no dents from the past years?
 * There are a few bumps on it. It ends up taking 2,500,000,000 years or so to complete, so 7,000 years wouldn't get very far.
 * This is made evident also in the montage where the Doctor doesn't get very far with the Shepard's Boy monologue until literally tens of millions of years have passed.


 * The obvious one. If all the rooms in the castle reset - how is the Doctor able to slowly wear down the diamond wall over multiple incarnations?
 * At a guess the resetting stops when the Doctor 'dies' and begins again when he 'arrives'. So the settings are as they were when he begins the loop again (all the rooms would have been rest by then to their 'normal' settings). The diamond wall room is occupied when the Doctor dies so the resetting stops when he has done some damage and stays that way until the loop stops with him inside it again. You may ask why, if this is true, do the bloodstains on the floor dispensary, to which I can only answer that maybe the floor is independently self cleaning?
 * But the rooms reset if the Doctor leaves for sometime, but i think if this material is harder than diamond is also hard to regenerate.
 * I view it as simple as this. Whoever trapped the Doctor in there would never have expected he wouldn't give so therefore never programmed the dial to reset that room, eventually leading to the long battle to destroy it. It's simply the unseen enemy's arrogance that results in the rom not resetting. As a side note, how do you replenish something 400x harder than diamond?
 * I thought the reset was because in the end everything ends up the same way it was before he came, so it seems to reset. Maybe I misunderstood the episode, considering how strange is was.


 * Every 100 years the bird (got from the writing in the sand) pecks at the wall, therefore what the doctor is doing is pointless.
 * The writing "bird" in the sand is meant to remind the Doctor of the story. There is no real bird.
 * Unless I really wasn't paying attention, I thought he was referring to a bird on an alien world that would eventually wear down the mountain or whatever it was, and he wrote it because he got the idea from the alien bird.
 * I'm afraid you really weren't, nobody mentioned any kind of alien world, and in the episode there was a wall, not a mountain, and as explained above, there was no real bird, the Doctor simply compared himself beating the wall to the bird pecking a mountain from the fairy tale.


 * Who put the very first costume in the fireplace room? or the first 12th doctor just put off the wet one, left it and went on naked? otherwise there'd be no extra costume for the next 12 and why didn't it disappear when the room reset? even if it's not supposed to be gone because it's like a part of something alien-not-castle-stuff, still the question stands - who put the first costume in the room?
 * The most likely answer is the one you give in your question - The Doctor takes off his clothes (possibly leaving on undergarments, as we don't see those there) to dry by the fire. He then goes wandering about, eventually dies and brings in a "new" Doctor. When he gets wet, he finds the previous set of clothes, and swaps them out. The cycle then continues.


 * This cannot be, as the room reset each time.
 * What OP means is where would the clothes have come from the first time the Doctor came. This is a good question -- the Doctor finding his clothes there suggest that those are the clothes left by the last Doctor. Thus perpetually the Doctor is putting his clothes there and picking up the wardrobe of his predecessor. But if there were no clothes the first time, the Doctor would and could not have left his clothing there. Various things could explain this tho. There could have been extra clothing in that room and the loop would still work, as this room clearly is one of the ones exempt from the reset. So a clown outfit could have been there and the room wouldn't put the clown outfit back because it doesn't reset. Or maybe there's clothes hidden elsewhere in the room that the Doctor doesn't find in all cases past the first one because he doesn't need to. Or possibly the first time he stripped his clothes down without another wardrobe and spent the rest of the episode after that point naked. I prefer the later possibility, and will now accept it as head canon.
 * And that's basically what the above explanation says - the first version leaves his clothes there, goes wandering about with out them (possibly naked, possibly still in undergarments), and the next version of the Doctor finds them.
 * This cannot be, as the Doctor does not know he has the ability to return.
 * Thanks for the answers, except I think the costume room does reset, as otherwise the fire in the fireplace would've gone out many years ago. I do like the idea of him finding some other clothes somewhere in the room or the castle (there was a bed, and food, could easily be a wardrobe too), and as you said, after leaving his own costume there for the first time, he never needed any other clothes to look for. And the costume doesn't reset because it is indeed something that the Doctor brought with him, foreign material and stuff. Seems legit for me.
 * Moffat has since stated that the first time the Doctor left his suit in that room, he found some generic clothes there to change into. That outfit got burned with that iteration of the Doctor, so all the ones to follow ended up wearing their predecessors' clothes.
 * Note, for example, that the Doctor finds food, and presumably the tools to create the portrait of Clara, so some things were provided to him (otherwise the Doctor might have starved to death). Presumably this included a change of clothes - we don't know that the Doctor didn't find them in another room initially.


 * What was the point in taking the panel from the floor, writing on it and burying in the garden? and if all the rooms except the wall one reset, why the garden and the floor didn't? The garden only resets to the grave being dug up back again, but that's not what it was like when the Doctor first got there. Or in fact he wasn't who dug it, the Time Lords were, so the dug up grave was a default? Why? To show him the way? But why so complicated?
 * See point above above he bird pecking on the wall every 100 years.
 * Sorry, still not getting it. The bird and 100 years is just a metaphor, in fact the Doctor every time beats the wall as often as he can. How does this answer my question? And what the Doctor is doing is the opposite of pointless, the problem is eventually solved exactly because he's been doing it for all this time. And if you mean that all other his actions are pointless because of resetting, I still want to know who dug the grave and depending on this why doesn't it reset.
 * If the moment a new Doctor clone is created the base state for the reset is made. That would solve the problem with the word bird not disappearing from the sand.
 * But not the Wall which i have two theories:
 * 1)The Wall room is non-resettable
 * 2)The Azbantium is too difficult to be "reset"
 * I think the first one is correct, if the TimeLords wanted it to be reset, they would made the wall of something more 'resettable'. I think they had no idea he'd do something like what he did, and as the wall was actually a gate of sorts, they never intended for it to reset - no need, it's not even technically a part of the castle.
 * I'm guessing the wall is the perimetre of the confession dial and so doesn't reset because it isn't part of the "World". I imagine that even if the timelords altered the castle to be a jungle or a town or whatever, the edge of that world would still be the same impenetrable wall.

Therefore, it does not reset.
 * If the rooms reset all the time, why the word 'bird' stayed on the sand for a while for the Doctor to read it, and was gone later? And why the castle started moving and opened a way to the roof when the Doctor saw this word? The Bird clearly means no good for the Time Lords, more like vice versa.
 * The doctor writes the word 'bird' when he is week, each new doctor reads it and wipes it away. When the room is reset the word is written there for him the read.
 * Both questions stand, why doesn't the word reset as everything else and why the way to the roof opened exactly when the Doctor saw the word. As initially, when the Doctor first arrived there (which is, as i understood, the state that the rooms are supposed to reset to) there couldn't be any such word, as there was no Doctor yet to write it.
 * The hypothesis above suggests that the reset value for the room is determined when the "new" Doctor arrives, or even as the "old" Doctor dies (being before the word has disappeared).
 * As for the bird thing, i now think that the Doctor's ashes it what the Doctor's basically become, it's a significant part of him, which can't be reset by the castle, which is why he chooses it to leave a message. And well, also because there's nothing else he can possibly reach at that moment. So no matter if the Doctor leaves the room or not, the word stays and it's blown away by the wind later.


 * The castle in the state presented in the episode is made up out of a mixture of bread crumbs left behind by the Doctor (and for some reason not reset to the default), bread crumbs(?) that are a default part of the castle and just random stuff and it's not always obvious which is which. What is clear, though, is that the first time (and possibly a few more after the first one) the Doctor is transported there differed from the sequence occurring ad nauseum in the episode. At what point did the Doctor set up the scenario as we saw it unfold? How much of it was actually set up by him and what parts were already part of the default castle? Also, how was the transporter activated the first time?
 * The Doctor had 7,000 years worth of attempts to setup the bread crumbs before we first join the episode. As to the first activation of the teleport, that presumably was set to occur after he was sent away from Ashildr in the previous episode. Each "burned out" version of the Doctor just needed to activate the special rematerialisation of the stored pattern.
 * Moffat has stated that the first go-around in the dial for the Doctor took years before he worked out the tricks.
 * However, the Doctor would have been killed long before working out the tricks, and as each new Doctor has no memories, he'd have to start all over again!


 * Why, for God's sake, doesn't the Doctor figure out something better to hit that wall with than his hands?
 * Put yourself in his position. If you were trapped inside that room with the Veil coming at you, how else are you going to go back and get that other thing to hit the wall with? Furthermore, I doubt using that other thing would actually get him out of that area faster
 * Aren't his shoes a harder surface to hit it with than his hands? Unless he's using some TimeLordery on his hands to make them really hard or something, it just seems silly. Ideally, he'd force a regeneration into some powerful creature with claws/pincers/whathaveyou that can more efficiently chip away at the wall, maybe even hold off the Veil while we're at it.
 * The wall isn't merely a physical object; it's a construct which embodies the boundary between the Confession Dial's pocket dimension and the rest of the universe. It's possible that mundane objects can't damage it at all, but being a Time Lord gives the Doctor the capacity to do so, much like how his Time Lord status let him keep moving when Time was being reversed in "Invasion of the Dinosaurs".
 * The shovel wasn't available because the Doctor doesn't remember what he's supposed to do until after he enters Room 12, by which time the Veil is blocking any chance of departure to retrieve the shovel. Also, the Doctor being a Time Lord, he likely does pack a stronger punch than if he'd used his shoes or something.


 * At the end we see everything took place inside a confession dial, but was it the Doctor's confession dial? If so, why was this what was inside it and shouldn't he have known?
 * Perhaps the dial was meant to extract the confessions out of the Doctor
 * That may be, but the Doctor lies about the Hybrid! He is the Hybrid, not a Timelord/Dalek combination.


 * Once on Gallifrey the Doctor casually reveals the secret he was so insistent not to reveal to the Veil just moments earlier. So why did he go through the torturous process of creating and sacrificing billions of clones?
 * Dialogue states he knows of only the legend of the Hybrid and he did state, just before he punched through that hard wall, that he would no longer be confessing to the Veil his knowledge about the Hybrid - which of course included the confession we heard at the end.
 * But the point was, apparently, not to not confess specifically to the Veil, but to not confess at all. I think the whole point of keeping the Hybrid secret was to protect Gallifrey. As he had no idea that the Timelords were those who tortured him (if that's true, things still can be not what they seem), he wanted to protect them and not to let the unknown torturer to learn the secret that he can use against the Timelords. And later, of course, when he realized it was all in vain and they were the ones who tortured him to find out the truth, and they were the reason Clara died (seriously, she was partly the reason of saving them, i hate those guys and would be glad if in the finale it's revealed they're actually innocent), he had no desire to protect them any longer, and thus revealed the secret with a quite clear warning about what now awaits them for everything they've done.
 * If he'd claimed to be the Hybrid any earlier, whomever was behind it could have just sealed Room 12 permanently and left him trapped in his Hell forever, or chucked the Confession Dial into a black hole. Hybrid menace foiled.  But once he's successfully escaped, the Doctor can make that claim with impunity: his captors have been scaring him to death for billions of years, so now he's free to start returning the favor.
 * This point is answered in "Hell Bent."


 * This is point four: Too many skulls. In the water the Doctor sees many thousands of skulls. He emerges from the water in the interior of the castle. Billions of skulls being added would eventually inundate the castle. The depth of the water within the castle walls can be estimated. 7000 years in the future gives the point at which we join the story. If he survives in the castle for a week, 52 skulls a year will be deposited. 7000 x 52 = 364,000 skulls.This amount does not rise above the water in the interior of the castle. If he adds the same amount until breaching the crystal wall he will add 104,000,000,000 skulls. The castle would overflow with skulls. Even if the skulls fall exterior to the castle the 'angle of repose' applies. Complicating factors such as currents, storms and the depth of the water exterior to the castle all lead to the same conclusion: too many skulls.
 * You have to remember that skulls don't last forever. They'll eventually turn to dust, allowing for newer skulls to take their place.
 * Indeed. Considering that the Doctor appears to live and die at a consistent rate by the time we hit this episode, the bones would decay and add up at a consistent rate leaving a perpetual collection of skulls.
 * The fact the Confession Dial is also one big TARDIS, for all intents and purposes, it might be automatically clearing away the skulls (otherwise the Doctor would at one point land head first into a pile of bone, rendering all the efforts to extract a confession moot).


 * How can each version of the Doctor specifically remember burning the previous ones when, technically, they haven't done it yet? Further, accepting that this is possible, why does nothing else in the entire castle ring a bell?
 * As i got it, he didn't remember it, he just figured it out. He guessed that's what happens every time, because that's what he was about to do. He says 'burning the old me' right before he actually does it, so. The only thing that confuses me is him yelling 'you don't understand, i remember it all every time', i don't know what he means, as he can't possibly remember something that happened not to him but to his copies. Some say he means 'i remember that no matter what i do you'll still be gone'.
 * Exactly how much he remembers is unclear, but by the end of a given body he may well have some recollection of the memories of his previous bodies. We know that Time Lords do have some psychic abilities, and trace memories from the previous versions of the Doctor may linger in the castle.
 * The "burning myself up to create another" is also a direct metaphor for regeneration and it's known the Doctor retains memories of his past incarnations.


 * Moffat has a long history of having episode titles that have very little to do with the story, but this time I'm completely lost. Why is this called Heaven Sent?
 * At one point the Doctor says, "I'm not scared of Hell - it's just Heaven for bad people." The main reason it's called Heaven Sent is to provide a contrast with the finale's title, in which the Doctor is "hell bent" on saving Clara. The pattern in Series 9 was to come up with titles that echoed one another i.e. The Girl Who Died/The Woman Who Lived, The Zygon Invasion/The Zygon Inversion, etc.
 * Yeh the linking titles seem to be the only real reason. Though I suppose the confession dial as a place Time Lords go to before death it's somewhat thematically related to "Heaven" albeit kind of ironically, when it was more purgatory than Heaven.


 * The Doctor says that the Hybrid is part Dalek/Timelord. The Doctor lies, for he is the hybrid. Why does he not die, when he lies?


 * If the Doctors memory is reset every visit, why doesn't he make the same mistake and die the first time, every time? Surely, the only way to survive is by learning from the previous mistakes, which is what happens! Therefore, his memories are not reset!


 * How did the Confessional Dial get to Gallifrey?


 * Where did the child come from that met the Doctor? Its the desert!


 * This might seem like a stupid question, but, when are the scenes in the TARDIS set?
