Theory:Doctor Who television discontinuity and plot holes/The End of Time


 * Why wasn't anyone surprised at Rassilon's appearance?


 * Time Lords recognise other Time Lords. The Doctor knew Rassilon, from the Time War and previously. The other Time Lords already knew the Lord President was Rassilon, hence no surprise.


 * How did Miss Trefusis time-travel to the end of the universe, where the Master's ring was located? How did she time-travel back to Earth? How did she know that the Doctor would leave the ring there?


 * The Master had hundreds of contacts, many that the Doctor didn't know about.


 * Also, the Doctor didn't cremate the Master in the year 100,000,000,000,000, he did it in a disused area or quarry that just looks like Malcassairo.


 * When the Master is restored to life, it is with a growth of facial hair, which he did not have prior to his death.


 * He had stubble when he regenerated into the Harold Saxon version of the Master, so arguably he is simply returning to the "default state" of this regeneration.


 * If Lucy has been in prison for approx 2 years, how could the Master's DNA still be on her lips?


 * It's demonstrated in DW: Smith and Jones that a quick kiss is enough for a genetic transfer. Presumably, since the Master kissed Lucy many times, the genetic transfer lasted long enough for it to be cultivated at a later date, the Master was clever enough to keep a portion of himself alive in the first place he could have also ensured DNA remained on Lucy's lips.


 * Both Lucy's voice and personality seem dramatically different.


 * Since Lucy has been in jail she has had time to think about her actions with the Master, and has seen how evil he was. Arguably, the first inklings of this "new" personality occur as far back as DW: Last of the Time Lords when she shoots and kills the Master, with the implication he had abused her during the year that never was. It is also stated she was under "the Master's spell" meaning she believed what she was doing was right.


 * When talking about their previous encounters, Wilf mentions his paintgun although the Doctor wasn't there when he shot the Dalek.


 * It's possible that Wilf informed the Doctor of his encounter with the Dalek while they were waiting for Donna to awake in DW: Journey's End.
 * Wilf is the one who mentions it, and he was there. The Doctor doesn't respond to the reference.


 * It is said that Martha is married to Mickey but isn't she supposed to be married to Tom Milligan?


 * It was established in DW: The Sontaran Stratagem that Martha was engaged to Tom and later it was stated in TW: Children of Earth: Day One that she was on her honeymoon. However, it is not stated as of who she is with. She may have been just married to Mickey and on her honeymoon with him.


 * Her relationship with Milligan obviously ended at some point and she ultimately married Mickey. The episode does not indicate when the Doctor found them - it could have been years later


 * Perhaps Tom died during the Meduca Cascade incident, and then Mickey comforted her and they ended up marrying eachother.


 * Why did the TARDIS explode during the regeneration scene? This hasn't happened before.


 * Regeneration is unpredictable, and some are more violent than others.


 * Alternatively, since he has held the regeneration back for an extended period of time since exiting the radiation chamber, it all blasted out of him at once, building more force the more it was held back.


 * The radiation the Doctor was exposed to could also have made the regeneration more explosive.


 * There is strong evidence that, unlike past regenerations, the Doctor delayed the change for an extensive period of time, long enough to not only visit the companions shown on screen in Part 2, but also, as revealed in SJA: Death of the Doctor, visit every one of his past companions. The pent-up energy from the Doctor delaying his regeneration could well explain the violence of the change.


 * If the regeneration was violent enough to destroy the TARDIS, why did it not at least rip his clothes?


 * Because the energy was shot outward from his body, instead of going inward.


 * Also, his clothes were "raggedy", a fact that was commented on repeatedly in the following episode.


 * Why did the Doctor choose to meet Verity Newman, a descendant of Joan Redfern, and not Redfern herself?


 * The Doctor has already caused Redfern a great deal of heartache and he likely does not wish to reopen old wounds.


 * As SJA: Death of the Doctor establishes more visits than those shown on screen, we don't know that he didn't.


 * If the Doctor saw Rose from 2005, wouldn't that create a paradox due to the fact Rose has not met the Doctor yet?


 * The Doctor stayed in the shadows at the end, not wanting Rose to see his face. She asked if he had been drinking, so she would have dismissed him as a drunk and likely not remembered him from the incident. Just as in DW: Smith and Jones, it is safe to do "tricks" like this that don't affect the timeline.


 * The room with The Gate was shaking because of Gallifrey coming closer, but then it stopped shaking when the Doctor picked up the gun. Why was this?
 * Gallifrey had reached some manner of "equilibrium point" in its approach to Earth.


 * In DW: Smith and Jones, the Doctor clearly states that he can expel radiation from his body if he focuses hard enough, so therefore why does he need to regenerate?


 * The damage has been done.


 * There is a misconception that all radiation is the same. In reality, there are several types and, as shown in several stories (DW: The Daleks, The Mutants, Planet of the Spiders etc.), it alpha and beta particle radiation is lethal to Time Lords (to a lower extent) while what's in the electromagnetic spectrum is near harmless to them (i.e., Gamma rays, Ultra Violet, X-rays etc.).


 * Furthermore, the Doctor was already in a weakened state after surviving the fall from the mining ship.


 * How did the Doctor survive jumping out of a moving spaceship, crashing through the skylight, and landing on the marble floor? A lesser fall onto grass killed the Fourth Doctor.


 * Physically, each Doctor is different and can be expected to be more or less durable than the others. In addition, the Tenth Doctor mentions he can survive a fall of at least thirty feet in the episode DW: The Satan Pit. Plus, he was also in the same room as the gate, which prevented him from dying, but not healing his cuts as he wasn't inside the gate.
 * Additionally, the Doctor planned his fall here, whereas his fall in Logopolis (TV story) was unplanned. Crashing through the skylight would also have somewhat broken his fall.


 * When the Doctor decides whether to shoot the Master or the President he holds the gun in different hands (left when pointing at the Master right when pointing at Rassilon).


 * You can see him change hands.


 * When the Doctor is aiming the gun at both the Master and Rassilon, you can see (and hear) that he has quite obviously pulled the trigger on each occasion.


 * The Doctor is holding the trigger close to the point of shooting a bullet: as he changes targets, he changes hands where he is holding the trigger closely to the point of firing each time.


 * If Rassilon's glove is so powerful why would he hesitate to use it when the Doctor points a mere revolver at him?


 * Even if he did fire, the Doctor would have time to fire as well, killing them both and destroying the link.


 * After the Doctor hits the Sontaran the scene cuts from a close-up shot to a full-body shot. However, no Sontaran is visible in the full-body shot.


 * The Sontaran fell off of the platform the Doctor was on.


 * Wilfred states that the Doctor mentioned regeneration to him during a previous encounter, although no such scene appears in previous episodes.


 * The Doctor did however explain Donna and the "Meta-Crisis" to Wilfred and Sylvia. This virtually necessitated at least a simple explanation of regeneration.


 * Why weren't Earth and Gallifrey both ripped apart immediately by gravitational forces when the latter materialised in such close proximity?


 * Gallifrey hadn't completely materialised yet, so it hadn't become solid enough for its mass to completely destroy the Earth.


 * The Doctor recognised that the person that was aiming a gun at Wilf was a Vinvocci for being 1 inch taller, suggesting that all the Masters were the same height, but when Joshua Naismith and his daughter changed, it is clear that the Joshua Master is taller than his Master Daughter.


 * In the scene where the Master taunts the Doctor of his newly created "Master Race", you can clearly see that both the Joshua Master and Abigail Master are the same height. In prior scenes where they were different height, the transformations wasn't yet complete.
 * Abigail Master is wearing high heels, but his head is at the same height as Joshua Master; therefore shorter.
 * Or he kicked them off. Those things reportedly aren't very comfortable. Once the transformation is complete, all the "Master Race" (*sigh*) are the same height.


 * The Doctor "has" to sacrifice himself to save Wilf by going into the malfunctioning radiation chamber. Yet while he is speaking to Wilf, the shot shows a fairly obvious gap between the door and the rest of the glass chamber. This makes his sacrifice seem a bit of a waste, as the door could have easily been opened (by force or otherwise).


 * The Vinvocci glass contains and absorbs the radiation, and trying to break open the door would have just caused the radiation to flow out from that unlocked chamber instead of into a locked chamber where it could be contained. This is why the doctor must switch the active chamber to his own.


 * The Doctor has gone through 10 regenerations (if you do not count the meta crisis one.) Some Time Lords had control over the process. If the Doctor has gone through this many, why has he not gained any control over the process?


 * Some Time Lords can control it better, just as different people have different strengths and weaknesses.


 * Additionally, the Doctor usually regenerates under extreme circumstances, giving him less control over the process.


 * In this case, he also held off regenerating for a significant period of time after being healed, which one would expect took much of his focus and control.


 * Luke (and by extension Sarah Jane and the rest of her team) are aware of the "Master Race" transformation, despite the fact that it occurred simultaneously for everyone involved, making outside observation of the effect impossible. Since everyone changed all at once, and then changed back, nobody could have observed it.
 * Luke may have been immune due to his unique biochemistry. Regardless of that, there was also recorded visual evidence from news cameras, security footage, etc. The transformation would also have been witnessed by Mr Smith and K9.


 * Luke reacts to the Doctor as if he's never met him in person before, even though they would have met during The Wedding of Sarah Jane Smith. His cut off line appears to be "It's you! You're the Doctor.", which would be odd since they'd already met before.


 * Luke clearly recognises the Tenth Doctor's face from their previous encounter, and he was in shock of him appearing out of nowhere, saving his life.


 * If the woman who speaks to Wilfred is a Time Lady, (she is seen with Rassilon on Gallifrey during the Time War), and the Doctor was said to have destroyed every Time Lord and Dalek in the war, how could she meet Wilfred? If she is dead, exactly how could she return and come to see Wilfred?
 * How she managed to contact Wilfred is intentionally left unexplained for the time being.


 * Donna's defence mechanism was able to knock out all of the Master race that was after her, yet when would the Doctor have had time to implant this if simply hearing about anything that happened with him would kill her?


 * The Doctor probably implanted it at the same time as he was wiping her mind.


 * Why didn't Donna die? She saw a flashback of the Doctor from DW: The Runaway Bride, and the Doctor specifically told Wilf that if she remembered him, she would die.


 * She would die. The defense mechanism which knocked her out would not work indefinitely, and he may not have known it would work at all. Technically her mind did "burn up".


 * Why does Wilf have a revolver? Only officers carry revolvers, yet he claims he was a private.


 * At the front only officers carry revolvers in the British Army. A private being issued a revolver at some point is perfectly reasonable.


 * The Doctor states he can tell if a Time Lord is around, so how does he not sense the woman whenever she appeared to Wilf?


 * She was just an apparition.


 * Before the Doctor regenerates he clearly must be using some sort of hair product, why wasn't his hair sticking up after his regeneration?


 * The Doctor's body changes completely so any hair product, if any (who knows what the hair of Time Lords can do), disappears with the old hair.


 * When the First Doctor regenerated into the Second, his clothes changed as well. The same was apparently true for Romana (although that happened off screen). If clothes can be changed and TARDISes set on fire, hair gel can presumably be dissolved.


 * When Rassilon kills The Partisan, she is destroyed immediately. Why would it take less time the first time, but not as quick the other times?


 * Much of the functioning of the glove is unknown. Despite this, it did take several seconds from the time he stood up till he destroyed the dissenting Time Lord. This appears reasonably consistent with the later scenes.


 * What was a baby Adipose doing alone at the bar without its parents?


 * Without knowing much of anything about the Adipose life cycle other than their creation, a great many possibilities exist - including that this was not necessarily a "baby" Adipose. Who is to say that Adipose looked different when they aged?


 * The Master sometimes used his energy bolts, and his flesh disappeared. Yet other times his flesh didn't disappear. Why would this happen?


 * When he used the energy bolts before, his flesh disappearing is most likely to be a coincidence.


 * The Doctor mentions the Nightmare Child in a list of horrors born in the final days of the Time War. However, in The Stolen Earth, the Doctor said Davros's command ship flew into the jaws of the Nightmare Child in the first year of the Time War.


 * It is possible that the Nightmare Child lasted throughout the Time War and the Doctor mentioned it because it was a good example of a great horror of the Time War.


 * Also, by the nature of a Time War, something created at its end might be present at its beginning.


 * Not necessarily a discontinuity requiring explanation, the High Council of Time Lords is revealed to be an enormous body (resembling the Senate in the Star Wars sagas). In earlier stories the Council was quite small, consisting of the President, Chancellor, Castellan and a few other high-ranking Timelords and Timeladies.


 * The Council consisting of the President, Chancellor, Castellan and a few other Time Lords that appeared in the Classic Series and the first scene of this episode is the Inner Council, while the Council resembling the Senate is the High Council which according to DWM Issue 100 is equivalent to a Parliament.


 * When the Doctor enters the TARDIS after hearing the Ood's song, his right hand starts to glow with regeneration energy. But when he walks around the console, the glow is gone.


 * The regeneration was just starting, and the Doctor was still putting it off until after he got the TARDIS away from Earth - i.e., the energy causing the glow was ebbing and flowing until he couldn't hold it back anymore, making the appearance and disappearance of the glow perfectly consistent.


 * The platform Rassilon uses to speak to the High Council changes shape completely from Part One to Part Two.


 * Those were two different times he was speaking, hence two different platforms - one a long plank before the vote was taken, one a hexagon after the vote was taken.


 * When the Doctor alternately threatens the Master and Rassilon with a revolver, both have time and the means to kill, maim or disarm him. Why don't they? And why does the Doctor think a mere bullet could kill the mighty Rassilon (who presumably would regenerate if he was killed) anyway?


 * The Master clearly no longer intended to kill the Doctor, and Rassilon wanted to give the Doctor a chance to join him. If the Doctor had shot Rassilon in the head, it would have killed him, and we don't know if Time Lords can regenerate from that kind of death.


 * The Doctor was resisting regeneration. When the Master did it, he died. Even though seeming to resisting regeneration would cause killing, why did the Doctor not die?


 * The Doctor delayed the aspect of regeneration which resulted in his physical change, however he had already healed. The Master had refused to allow his body to even begin the healing process, therefore he died from his gunshot injury.


 * Alternatively, the Master's and the Doctor's holding-back could be different; the Doctor may have merely belated it, the Master committing suicide.


 * When Wilfred goes to help the technician out of the Nuclear Bolt room, the technician is showing the effects of the Master's template; however, when Wilfred goes in, it heals.


 * The Doctor stated that he had to filter the levels before the chamber could be used to cure Wilf of the vision of the Master.


 * The Doctor was seemingly acting evil when deciding whether to shoot the Master or Rassilon. Wouldn't this make the future where The Valeyard exists concrete?


 * He wasn't acting evil. He simply seemed willing to go to the extent of killing one of them in order to save all of creation from Rassilon's "final solution".


 * Remember that the Doctor already "used the Moment" to wipe out the entire Dalek and Time Lord species (at least as far as he knew). If you can accept that as the lesser of two evils, accepting shooting Rassilon as a possibility seems pretty easy.


 * How did the Doctor put off the regeneration for so long? Isn't regeneration supposed to happen immediately? With the Doctor putting it off that long it seemed as if the damage had been repaired and he wouldn't need to regenerate.


 * Taking the points in order: The Doctor put off his regeneration so he could say goodbye to his friends. Regeneration does not always happen immediately, it depends on the manner of death, how much damage is done, and how quickly. And the damage was not repaired; Some of the initial regeneration energy healed the Doctor's cuts, that's all.


 * If the tracking on the asteroid lasers is automatic, the only thing required of the gunner being to "deploy the trigger on the joystick", then what is the point of the gunner?


 * Perhaps the point of this is so that the gun can be fired when it's aiming at a particular point, which the automatic tracking can't identify.


 * The Master is a Time Lord, why does his pattern in the Immortality Gate even work on humans? Why only on humans, why not the Vinvocci, why not on the Doctor, the only other Time Lord on Earth?
 * The Master did reprogram the Gate. He made it work so it would affect only humans, perhaps he didn't take the others in the account, perhaps he wanted or needed The Doctor to survive. And obviously he programmed it so it would copy his own DNA.
 * He didn't know of the Vinvocci intruders at that point, and due to his amusement to the Doctor's shock. He would probably consider it boring to turn his worst enemy into just another copy of him.


 * When the Doctor pulls out his sonic screwdriver and says 'even this will destroy it', it has three prongs like the Master's laser screwdriver, when the sonic has only one?
 * It doesn't. It's a trick of the light. It's the same screwdriver.


 * It has been stated in various sources including by Russel T Davies, Julie Gardner and John Simm himself that the Master's hair is definitely blonde in this story. The explanation for why his hair was blonde was that he needed to alter his appearance since he looked like former Prime Minister Harold Saxon. However, when he enters the Immortality Gate and transforms every human into anther Master they too have bleach blonde hair. If their DNA is being changed to transform them into all into Masters how can they possibly have dyed hair since hair dye isn't a part of the Master's genetic make-up.
 * The Master would not have cared if he still looked like Saxon. The most probably explanation is that the change of hair colour was by changing his DNA.
 * No one has confirmed that the Master's DNA changed to allow for the change in hair colour. I believe in a podcast the executive producer refuted the claim that his hair has changed by any means other than hair dye (they note that the root of his hair hasn't changed). Since we don't have any better explanations, it could be that the trauma of the Master's botched resurrection coupled with Time Lord Regeneration abilities (and the fact that he is dying/aging) has caused his hair to strangely change to blonde (I say strangely because the roots are not blonde). RTD has stated that the Master elected to change his hair colour since he looks like Mr Saxon, so perhaps he achieved the change through a conscious effort at manipulating his artron energies to force the change (a kind of small-scale controlled regeneration; it is shown he can manipulate his energies to fire lightning bolts so why not). This effort might be difficult to sustain and/or painful thus why it isn't more extensive (i.e. why he doesn't just change his entire body to avoid recognition)


 * It is established here that the Master has indeed heard "the drumming" throughout his life, since he was a boy on Gallifrey. Yet he never mentioned it nor gave any indication of it prior to being Professor Yana.
 * It's of course possible (although admittedly unlikely) that he never mentioned it to the Doctor previously, despite being best friends/enemies for so long.


 * The Time Lords seems to know that the Master hears "drumming", even before they decide to send the signal back to him as a boy (and therefore that they are the cause of it). Yet the Doctor showed no recognition of it when Professor Yana spoke about hearing drumming in DW: Utopia.
 * It's of course possible (although admittedly unlikely) that he never mentioned it to the Doctor previously, despite being best friends/enemies for so long, and the high council knew about it through other means not available to the Doctor.
 * It's also possible that during the Delgado Master era the drumming might not have been as noticeable, perhaps subliminal. And considering the Ainley and Roberts Masters were not actually Time Lords, but the Master inhabiting Tremas of Traken and Bruce the paramedic, the drumming may have manifested itself in a different way, if at all, only to return in full force when the Master was finally revived as a full Time Lord.

Its been a while, his hairs grown, and he proberly dyed it. It was down to a freak accident during his reserection.
 * How come when the Master was brought back to life his hair is shorter and darker but later he has hair a bit longer and is blonde.
 * How exactly did the Master aquire his powers?
