Theory:Doctor Who television discontinuity and plot holes/Journey's End


 * How is one person with time lord intelligence able to destroy the daleks when they are at full power yet the entire time lord race are unable to over several years.
 * Because Donna was in the same room as the device which had absolute control over the Daleks.
 * Also all these Daleks are made using Davros DNA which the Daleks in the time war weren't so they would be able to build a machine connected to every Dalek in egsistance


 * Donna cliams she is able to use her time lord intelligence better because she is a human, but it is the doctor[a time lord] who has been defeating the daleks for years easily he eradicated their home planet stopped their invasion of earth why is the doctor so utterly useless in the face of davros, so easily overpowered terrified unable to beat him without the aid of his assistant bit different to the seventh doctor's "every time our paths have crossed I have defeated you"


 * When the spotlight then comes on onto Caan, Rose questions what the creature is. Having seen the true Dalek form before (DW: Dalek), shouldn't she know what it is?
 * It's not just the Kaled mutant she's asking about, it's also the destroyed Dalek casing, the fact that it is chained up, and that it's cackling maniacally under a spotlight.


 * If the Doctor under went a regeneration (stopping it short if changing his appearance.) Then surely he would still under go regeneration trauma of some sort.
 * The Doctor states that the process first repairs him then changes him.
 * If that's so, then why would regeneration require him to alter his appearance at all? If it starts out by just repairing the original body to (apparently) perfect health, why bother to change it afterwards?
 * Because that is the process of regeneration. Regeneration is a natural thing and was not created, so the processes cannot be altered.
 * Also, possibly because there would be no point in keeping an older or more frail body, than changing to a new one.


 * By destroying every Dalek including the ones on Earth the Doctor would have killed the Dalek that featured in the episode Dalek thus making the events of said episode completely non-existent.
 * That Dalek's dalekanium wasn't receiving power from the Crucible. The Doctor Clone destroyed the Daleks by maximizing the power feeds and blasting them back.


 * If the Reality Bomb destroys every reality, surely the Doctor would have had to prevent alternate reality versions of Davros from detonating reality bombs, lest they destroy this reality as well?
 * As there is only one version of the Doctor across all realities the time war only happened in 'our reality', so only one version of Davros as part of Time War exist.
 * It hasn't been stated there aren't any parallel versions of the Doctor.
 * Also if there was no doctor in an alternate reality then surely the Daleks would advance greater than these one as there would be no doctor stopping their plans.
 * The Doctor says a New reality is created by every decision we make. So I personally think this Anti-Monitor based weapon would only destroy the 'Nearest' universes, as in closest to them.


 * If Dalek Caan wanted destruction to come to his race, why didn't he just kill himself rather than doing an emergency temporal shift, rescuing Davros, and allowing Davros to create an entirely new race of Daleks to be destroyed?
 * It was his emergency shift that helped him see what the Daleks were - but by that time, he had already saved Davros, so it was too late to stop him.


 * Some of the scenes used in the flashbacks of people that have died for/because of the Doctor are scenes that the Doctor hasn't witnessed, for example, Harriet Jones's extermination that the Doctor hadn't found out until Davros mentioned it, also in the scene where the Hostess sacrificed herself, the Doctor was in a possessed state.
 * The Doctor is aware of these individuals dieing, so he has a retrospective moment in response to Davros' statements. The scenes shown are for our benefit, and not necessarily the only ones that the Doctor was "picturing" in his mind.


 * Wouldn't destroying reality change Dalek history, e.g Dalek invasion of Earth.
 * The Daleks' ultimate goal is to become the supreme creatures in the Universe. Destroying reality would do this, so the existence of any past invasions would be irrelevant to them.


 * If any mention of the Doctor or the TARDIS would cause the Time Lord consciousness within Donna to reawaken and burn up her mind, isn't the Doctor taking a tremendous risk by letting Donna see him in the Nobles' house?
 * The Doctor said tell, so seeing him won't kill her unless someone tells her who he is.


 * Why didn't Davros activate a holding cell on Donna when he did with everyone else?
 * Davros didn't place a holding cell on Martha, Mickey, Jackie, Sarah or Jack, either. Donna had been zapped and knocked unconscious, so it would have been very unexpected for him to put a holding cell on her.


 * The DoctorDonna immobilises all the Daleks but yet the Supreme Dalek descends to the vault and destroys the Magnetron. Also they stopped all access to the vaultso the supreme dalek wouldn't of had access there anyway
 * The Supreme Dalek is twitching as it descends. It probably had a personal backup power source.


 * Doctor Donna incapacitates the Daleks by manipulating keys. Why are there keys that could only be manipulated by hands on a Dalek vessel?
 * Davros has humanoid hands he could have used to keys. Some Daleks have claws instead of plungers.


 * When the Earth was returned to its rightful position, the moon is seen to be still in its place (it did not travel with the Earth as we must assume the satellites and the rift did) and presumably resumed orbit. Wouldn't it have floated off toward the sun or another planet without the Earth's gravity to keep it in place?
 * The Earth and the Moon actually revolve around the Sun as a unit as they also revolve around each other (as the Earth in much more massive, the center of revolution for the Earth-Moon system is actually beneath the Earth's crust). If the Earth suddenly disappeared, the Moon would continue to travel around the Sun in the Earth's orbit. Granted, recapturing the Moon and putting the Earth-Moon system back together would be an interesting exercise in celestial mechanics, but two Doctors and a Doctor-Donna are certainly up to the challenge. The Doctor acknowledges that the Earth is in for a period of unusual weather patterns, likely caused by the Moon reinstating itself.


 * To get Earth home that quickly they would have been going at the speed of light and as the Doctor explained in The Stones of Blood traveling past the speed of light causes the traveler to arrive at their destination before they left, meaning they could have arrived not to soon after Earth left its original place.
 * Given the distances involved, it seems unlikely the TARDIS "towed" the Earth through normal space-time. Plus the earth had been missing for quite a long time, so maybe it arrived just after the Tardis dematerialised to head for the Shadow Proclamation.


 * When the Doctor remembers those who have died because of him, he recalls characters from the Ninth Doctor era, so shouldn't he also remember individuals such as Adric, Katarina and Sara Kingdom, too?
 * Normal tendency would be to remember the most recent ones first. Whether they cross his mind at all or not in those few seconds is of course unknown. From a storytelling perspective, it makes more sense to include flashbacks to recent guest stars.


 * When the Doctor Donna seals the vault how is the Supreme Dalek supposed to descend upon it?
 * The Supreme Dalek has the authority or codes to override the seals.


 * The Dalek sealed in the time bubble at Torchwood should not have been destroyed when the other Daleks were. It would have been insulated from all events occurring in time.
 * It is unknown how a time lock functions.


 * If the Medusa Cascade has been taken a second out of synchronization with the rest of the universe (as stated in The Stolen Earth), then how is the Reality Bomb detonation supposed to affect anything outside the Medusa Cascade?
 * The signal that was sent to the Doctor by Torchwood managed to reach the normal universe, so the reality bomb can as well.


 * How can the TARDIS tow the Earth back home if the Medusa Cascade has been taken a second out of synchronization with the rest of the universe?
 * Given the distances involved, it seems unlikely the TARDIS "towed" the Earth through normal space-time.


 * Why was Davros not shocked to see that Jack was alive after being exterminated?
 * He was not present for the actual extermination, hence didn't necessarily know he had been shot.


 * Wouldn't Donna see something on the news about the Earth moving and burn up?
 * As the Doctor said, she'll think it of a "Donna Noble story where she missed it all again". By the end of the episode, she was already discounting her friend's account of the story on the mobile phone.


 * Why hasn't Caan been given a new "casing" after being damaged in the Time War?
 * The disdain that the Daleks show for him is apparent, calling him "The Abomination" it is likely they did not consider him a Dalek.


 * If the Reality Bomb could destroy all universes then wouldn't a reality bomb from a different universe then destroy the Daleks?
 * The reality bomb does not target Daleks otherwise their bomb would destroy them.
 * No, Davros explains that the Daleks are safe because of the Crucible. Clearly, the Reality Bomb would destroy any Daleks in other universes (unless they were busy detonating their own Reality Bomb in their own Crucible at the same time), but so what? Davros wants his Daleks to be the supreme masters of creation, not some other Daleks that may have been created by some parallel-universe Davros.


 * Gwen and Ianto use their guns against the Daleks knowing that bullets won't harm them. However, Torchwood does have more advanced weapons, as seen in Something Borrowed.
 * Gwen may not know where some of the more powerful weapons are or have the strength to lift them.


 * In Doomsday, when someone used a dimension jump device, they stayed in the same location as they were before they jumped. So, surely, when Mickey and Jackie travelled from their parallel universe, they should have been teleported to the Earth's original location, and ended up jumping to where the Earth used to be? Also, what a coincidence that they landed just where Sarah Jane was about to be exterminated?
 * It's very possible they've had time to perfect the technology. Also, Rose was on the planet. For all we know they were tracking her location and altered their transit system / reality jumping devices to compensate for the move of the planets.
 * Location in Space is relative. The two Earths are linked together, even if the one is moved. They may have a way of viewing their destination in the other universe before jumping, and thus deliberately jumped to save Sarah Jane. It would also explain Pete's handy rescue of Rose in DW: Doomsday.


 * If the Doctor has a device that can rewrite biology why does he not simply remove Donna's Time Lord DNA but order the TARDIS not to remove Donna's memories of her real self as it did in Human Nature (TV story)?
 * The Arch is used for Gallifreyan biology not Human biology.


 * When the Doctor and all his companions are inside the TARDIS at one point Martha looks directly at one of the cameras.
 * From her point of view she is looking at the Doctor.


 * When a Dalek says "exterminate!" when about to kill Donna, its dome lights do not light up.
 * When multiple Daleks are on screen, the lights blinking allows the audience to know which one is speaking; it would be a bit of discontinuity not to have them blink even if the Dalek is alone. Traditionally the lights flash on the syllables, so the lights should have blinked 4 times for "exterminate".
 * It is possible that the dalek you see doesn't actually say the word "Exterminate!". As there is more than one Dalek it is likely that one of the Daleks you don't see actually says the word "Exterminate!".


 * Towing the Earth at light speed would cause a lot more than shaking on Earth.
 * As mentioned above, it's not literally "towing". Given the distances involved, it seems unlikely the TARDIS "towed" the Earth through normal space-time.


 * The Supreme Dalek shows the Doctor, Rose and Jack a screen of the TARDIS in the core, surely they would have seen the TARDIS dematerialise.
 * They saw the TARDIS sink into the core, and it dematerialises at the moment they were expecting it to disappear due to its destruction.


 * Why didn't the Doctor remember Bliss if he remembered the rest of the Abzorbaloff's victims?
 * Bliss was placed on the Abzorbaloff's behind, so the chance of seeing her was slim.


 * Why does The Doctor remember Ursula when she was saved by The Doctor in Love and Monsters from absorbing into the path. It was clear she survived and had'nt died so The Doctor never needed to remember her?
 * Even though she didn't die, the Doctor would still feel guilty because of his intervention in her life caused her to nearly die.


 * Sarah Jane Smith claims her son Luke is 14 when he was grown as an adolescent about a year ago.
 * Luke is consistently referred to as his equivalent biological age throughout SJA, however, presumably for convenience rather than retelling his entire creation story every time.


 * If this (very public) event happened in 2009, why does Henry van Statten not recognise the Dalek in 2012?
 * There is a good chance that Henry van Statten had seen the Daleks during their invasion. But considering that the Daleks decided to simply declare extermination then proceed to perform the invasion rather than actually publically announce themselves in detail. As a result, it is unlikely that members of the general public were even aware of the Dalek's motives and who they actually were.Or maybe him and his team was in his underground base at the time and not seen the event. It is unlikely he would have missed it, the whole earth moved and van statten investigates something even if it is just a light in the sky. Also the public are aware of the daleks as evidenced by adeliade and others who mention them, if he didn't know about them and he's supposed to investigate aliens he would have to be pretty stupid.
 * The Doctor states in Flesh and Stone that the event was erased from history by the cracks in time, so nobody except the Doctor should remember it, therefore Henry van Statten wouldn't remember or recognise the Dalek.


 * Before Donna loses her memory, there are flashbacks of her adventures which are seemingly parts of her memory. But one of the flashbacks is from the parallel world created around Donna, which she had trouble remembering when the timeline was mended.
 * It's entirely possible, that during the process in which her memories were erased, the Doctor purposefully brought some fleeting fragments of Donna's time in the alternate reality to the forefront for him to erase.


 * Why do none of the Daleks in this episode or the previous one possess force fields?
 * Since Gwen and Ianto's bullets do not effect them, it is likely that they did have forcefields, but there weren't any of the usual slow motion shots that showed them.


 * Why do the Daleks need the entire human race alive for one experiment? Couldn't they have just got a small and unintelligent animal, and test it on that before the plan goes into action?.
 * It is only one experiment, and the Humans are an enemy of the Daleks, and an ally, and favourite race of the Doctor, so it is not that extreme that Daleks would test it on the Humans, and why would they test on animals when they have Humans to terrorise. Because the Doctor says the Daleks fear him (DW: The Parting of the Ways) and wouldn't risk him catching up to them. Also, the Daleks are 'slaves' to logic (DW: Destiny of the Daleks) and wouldn't risk keeping a planet alive that are full of 'pests' that they know have caused interference with their plans. Also the planet itself may have been integral to their plans and why not start with the humans as they have most likely been the most recent planet taken.


 * If the TARDIS translates everything for anyone who's been in it, why didn't it translate for Martha when she first arrived in Germany?
 * Because the Tardis was not on earth at the time, and Martha could speak German.


 * Why does the Doctor have to remove Donna's memory after the Human-Time Lord Meta-Crisis and not the Meta-Crisis Tenth Doctor's? When the Doctor says there has never been a Human-Time Lord Meta-Crisis before now saying that Donna knows why, which she responds "because there can't be", he proceeds to wipe her memory of him. If "there cant be" why can the Time lord-Human survive yet the Human-Time Lord can not?
 * The reason why the Human-Time Lord cannot survive is because her human brain can't handle the expanded consciousness of a Time Lord. A Time Lord, however, could easily handle a human consciousness without ill effects.


 * If the Children of Time refer to the companions in this episode, can old companions such as Jo Grant, Peri Brown and Ace be considered as being members of the Children of Time?
 * It's just a poetic term being used by Caan and Davros. It doesn't have a specifically designated membership.


 * The point of regeneration is that is changes your body because it is dying not that it heals the one you already have, but the Doctor implies changing bodies is just a side-effect of regeneration.
 * The exact steps that a regenerating body goes through have always been left vague. Each regeneration adds a little more to the mystery surrounding it.


 * Davros stated in the previous episode that he created all the Daleks on the crucible after being rescued by Caan. If so, why did he not condition them to be subservient to him, like he did with the Imperial Daleks, rather then suffer their mistrust, and basically be enslaved by them?
 * Daleks are self-deterministic, and Davros wants them to be so that they can indeed become the supreme form of life in the Universe.


 * The multiverse is infinite, so couldn't it have universes without matter? And even if there aren't, can't the multiverse grow back?
 * Assuming Davros & the Daleks know this, he likely accounted for it. All realities of all types will be affected.


 * During the doctors aborted regeneration, when he poured the extra energy into his cut off hand, his head temporarily disappeared. why did this happen?
 * It didn't. It was obscured by the energy pouring out of him.


 * In the deleted scene,The Doctor says that Pete's World is need of defending,giving his Meta-Crisis Clone a chunk of TARDIS so that he can "grow" his own TARDIS. However,it is established before that the TARDIS draws its energy from the universe it was created in,hence it would be futile in the first place to "grow" a TARDIS from the TARDIS coral because it belongs to The Doctor's universe.
 * The "TARDIS" hasn't been created yet. It's just coral, so when it grows, it will be able to draw power from the "diesel" of Pete's Universe.
 * Perhaps more importantly, the scene was not televised. So far as we know, it didn't happen.


 * When the TARDIS lands in the park after towing earth back, people are walking around and acting like it's a normal day. they would most likely still be panicking about the invasion, or celebrating about the earth's return.
 * They are most likely used to things like this eg. Doomsday, The Christmas Invasion.


 * InDW: Turn Left, Rose mentions that Ianto and Gwen died destroying the Sontaran Mothership and that Jack had been transported to Sontar. Presumebly, therefore, Rose had somehow learnt, when she was jumping between parallel worlds, that Jack had been rendered immortal (by her, but she may or may not know this). However, when Jack is exterminated by the Supreme Dalek, she reacts with shock and mourns him - only to be suprised when he appears on the intercom alive and well. Shouldn't she know that Jack would revive?
 * She doesn't know that Jack is immortal. She only knows that he has been transported to Sontar.


 * When placing the Osterhagen Missiles then they would disturb the gunk which turned people working on the Inferno Project into Primords and would have eventually destroyed the earth. (Following DW: Inferno)
 * Not necessarily. We don't know how deep they drilled, and we don't know if Stahlman's Ooze is everywhere under the Earth or only in certain places.


 * As the Doctor said there are an infinite number of parallel worlds with different choices and outcomes, then there would have to be at least one where Davros succeeds in detonating the Reality Bomb, destroying reality.
 * That only happened in the one reality.


 * As they are using the TARDIS to fly earth I noticed the scene with sarah-jane pushing a hand break is repeated, first in an overview of the entire team then again with a close-up she is doing this twice and whether she is supposed to it twice or not i always point this out to myself as a mistake
 * How is pressing the brake twice a plot hole or discontinuity?


 * Why does the Doctor say the duplicate doctor is so dangerous? He committed Genocide to the Daleks many times.
 * No, he refrained from committing genocide multiple times. He at somepoint caused the destruction of the Daleks and Time Lords once during the Time War, but the circumstances of that are unknown.
