Theory:Doctor Who television discontinuity and plot holes/Resurrection of the Daleks


 * The gun-carrying, near-murderous Doctor of this episode seems wildly out of character.
 * This is examined as a key point of the story, as is later repeated in Dalek. Davros is responsible for death and destruction of billions of people and worlds due to the creation of the Daleks. The Doctor wants to destroy the Daleks and stop any more destruction. He ultimately cannot bring himself to pull the trigger.
 * This conflict within the Doctor, especially s regards the Daleks, has already been explored in Genesis of the Daleks. The Fourth Doctor faces the choice between genociding the Daleks and preventing billions of deaths and unmaginable misery, or taking the moral high ground and permitting he evil to continue. This is referenced by the Fifth Doctor in his dialogue with Tegan before he goes to kill Davros.


 * Why do the Daleks allow Turlough to wander freely? This is not necessary in order to use him as bait.
 * Neither do they need to contain him. They see him as no threat.


 * Davros, although aware of the Movellan War, is surprised and fascinated by the problem of the impasse. Yet in DW: Destiny of the Daleks he was aware of the problem and even actively worked on solving it.
 * He still finds the situation fascinating.


 * Despite having spent his time in suspended animation he has been able to make his mind control device and has learnt enough about Time Lords to deduce that they're 'all soft'.
 * Davros' primary contact with Time Lords has been the Doctor. To the creator of the Daleks, anyone who shows compassion or mercy is soft. Taking the Doctor to represent Time Lords, he would undoubtedly consider them soft. The Daleks, based on their knowledge of and interaction with Time Lords, would undoubtedly agree. As for the mind control device, it is safe to assume that at some point Davros had to be transferred from the holding cell on the Movellan ship to the permanent cell on the space station, not to mention was presumably unfrozen for the duration of his trial. During that period, the modifications to his life-support chair were carried out, and he took advantage of the time to construct his concealable injector device, but did not find an opportune moment to use it.


 * Davros appears to distrust the Daleks, and declares that they will not abuse him again. Yet in Destiny they were slave-like in their obedience.
 * The Daleks in Destiny of the Daleks were desperate and manipulative, Davros has had time to reflect on and learn to distrust their suspicious reversal of loyalties.


 * Who are the prisoners who escape at the start? Duplicates? The originals of duplicates?


 * Why use duplicates as soldiers, rather than to infiltrate?
 * They are simply a resource the Daleks have available and are willing to expend.


 * Why are the cylinders of Movellan virus left on 1984 Earth, a planet that the Daleks want to invade? It's a bit like the Allies hiding an atom bomb in Berlin.


 * When Tegan handles a cylinder she remarks on how light is. But later it takes two Dalek agents to lift one.
 * It's not a matter of weight, it's a need to be very careful as the contents of the cylinder will kill their employers.


 * How do the Daleks have duplicates of Tegan and Turlough? The 1984 Earth soldiers appear to be duplicated in an extraordinarily short time. And why do the Daleks make such a fuss to keep the Doctor alive to clone him, when they can clone dead people as well?
 * Davros needed him alive to copy his memories, which he explicitly mentions wanting to do.


 * How are the Daleks able to view what's going on inside the station from their own ship?
 * Being a prison ship, they would have to have video cameras.


 * Why does Davros immediately assume correctly that Lytton and his troopers are working for the Daleks after they unfreeze him?
 * The Daleks are likely the only creatures in the universe that would want Davros free. The obviously Dalek-inspired design of Lytton's headgear probably also helped convince Davros that his creations were behind the attack.


 * Why do the duplicated Earth soldiers attack Davros's Daleks with weapons they know will not harm them?
 * Their weapons actually do work against the Daleks, as is seen when they managed to disable a Dalek earlier in the story by shooting out its eye stalk.


 * When the Doctor is captured by the Daleks he asks where Davros is. But he does not know that the Dalek ship is docked onto the prison ship where Davros was held, let alone that he has been released.


 * The Dalek plan to infiltrate Earth with their duplicates is never really explained. At the end of the story the Dalek Supreme tells the Doctor that the duplicates have infiltrated Earth. The Doctor explains to Tegan and Turlough that these duplicates will become unstable like Stien. Does this mean they will die, or that they will lose their Dalek conditioning? In the meantime, could they not they create chaos on Earth?
 * At the end, Turlough suggests they inform Earth's authorities, and the Doctor agrees, so that is what they most likely do after leaving Tegan.


 * When the Daleks discover the Doctor they mean to exterminate him. Lytton appears and tells them that the Supreme Dalek wants him alive. One of the Daleks electronically confers with the Dalek Supreme and confirms this. Why would the Dalek Supreme give this command to Lytton, who is not entirely trustworthy, but not to the party of Daleks sent to the Doctor?
 * The Dalek Supreme believes that they have enough control over Lytton's actions that they have put him in charge of the mission. Logically, he would have more information form the Dalek Supreme than the Dalek soldiers.


 * Later, when the survivors of the ship's crew are killed in the self-destruct chamber, a Daleks tells Lytton it must inform the Dalek Supreme. But it physically leaves.
 * The camera just switches to focus on Lytton. You can actually hear the Dalek electronically communicating with the Supreme Dalek in the background. It just doesn't appear in the shot itself.


 * Why does Davros look so different to when we last saw him in DW: Destiny of the Daleks?
 * A new mask was created with a 'sagging' effect to simulate the years spent in cryo-stasis


 * How does does the Dalek Supreme survive the contagion or the destruction of the prison ship?
 * The Supreme Dalek was on the Dalek ship; the Movellan virus likely never got a chance to spread there before Stien set off the self-destruct. Odds are the Supreme didn't survive the events of the story, as it is never seen again after the prison and the Dalek ship are destroyed.


 * Leela doesn't appear on the scanner.
 * The Doctor has an inkling of the Daleks' plans, so tries his hardest to hide his memories of the one person he knows the clone will encounter on Gallifrey, and the one person he knows will kill the clone if she thinks it's dangerous.


 * Why wasn't Stein killed when he was shot with the Dalek death ray?
 * His survival for several seconds may be due to a quality given by the duplication process or the Dalek conditioning. As agents of the Daleks the duplicates might be expected to be stronger than the originals.


 * The title of the story seems odd, given that the Daleks revive Davros because they are dying, not resurrecting. And the effect of reviving Davros is their near total destruction.
