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


 * The room and connecting corridors where Davros is found look nothing like they did in Genesis of the Daleks. Further more Davros was left for dead in a bunker, not the Kaled city as stated in this story. ::The bunker was attached to the Kaled city. Davros also would likely have been moved by the Daleks in the intervening time.


 * Why do both the Doctor and the Daleks look for Davros, assuming him to be alive?
 * The Daleks had ample time to realise that his life support system would have allowed him to be still live. The Doctor searches for him because he knows that must be what the Daleks are after.


 * Why does Davros revive as soon as he is discovered?
 * He revives once a humanoid life form is nearby.


 * Why does Davros immediately seek out the Daleks, given that his last memory of them is of being shot by them?
 * Davros is arrogant enough to believe the Daleks would willingly follow him, despite their past betrayal, which, in a way, is correct.


 * Why does Davros not express astonishment at seeing the Doctor again?
 * In Genesis of the Daleks, the Doctor explained that he could travel in time.


 * The Daleks' attitude to Davros is one of unquestioning obedience. But they 'killed' him in the belief that they were superior to him and thus he was unnecessary to them. Why not simply command Davros to obey their will rather than submit to an inferior being?
 * If Davros dies they lose their advantage against the Movellans and it’s against Dalek programming to lose. So instead, they make him think he is in charge. They use a similar tactic in The Power of the Daleks, in which the three reactivated Daleks make the colonists think that they are in charge. This was a ploy by the Daleks to get the materials they needed to reactivate the Dalek factory and build new Daleks. Once the colonists' usefulness had ended, the Daleks began exterminating them.


 * The Doctor detonates the explosives in order to kill Davros. Yet without knowing that the explosives did not kill him, he assumes he is still alive afterward.
 * The Doctor knows Davros is resilient and that the Daleks had time to potentially remove the device.


 * The Daleks state that "Self sacrifice is illogical; therefore, impossible." Then why do they strap bombs to themselves ready to blow themselves up?
 * The Daleks will not blow themselves up; they are just carrying the explosives into optimal position. Davros planned to detonate the explosives himself. Since he is not bound to logic, the Dalek's argument does not apply to him.


 * Several references are made to the Daleks as 'robots', like the Movellans. The Doctor makes some of these. Davros does too. This is in apparent contradiction to other Dalek stories, such as Genesis of the Daleks and The Daleks, where they are described as mutant humanoids in mechanical casings.(In The Daleks they are mutated Dals; in Genesis, mutated Kaleds).
 * Their behavior in regards to the war with the Movellans is equivalent to that of robots, hence it is a fair approximation for them to make.


 * Romana says that they 'were once humanoid themselves', though under Dalek interrogation by a lie detecting device she had said she knew 'nothing about Daleks'. According to the information text of the DVD release the scripted line was 'I don't know anything about Dalek operations'. The same text suggests that either the on-screen line was misread or Romana was capable of misleading the Dalek truth detector.
 * Romana was either capable of misleading the truth detector, or believed what she was saying to be truthful, even if it didn't come out sounding as she had intended.


 * As Commander Sharrel reads the information of Davros off his computer screen, he states that Davros' species is mutant humanoid when the screen reads humanoid mutant, He also says mutant before it appears on the screen. And 'mutant humanoid' is not a species; it is a descriptive term.
 * He is not reading the information off the screen, he is entering the information into their databanks. They further obviously have a different classification for mutant humanoids than "regular" humanoids. As for "humanoid mutant" vs. "mutant humanoid", they are very clearly synonymous terms.


 * The Doctor sees a tomb stone marked Romana - how did the slaves find her name out? (she never told them).
 * She obviously told them 'off screen'.


 * Romana's regeneration in the beginning is inconsistent with the depiction of regeneration as a traumatic event with strict limitations. She was seen trying out various new appearances as if trying on new clothes. The Doctor has never had this kind of control over his regenerations and a statement in Castrovalva indicates that with regeneration "You never know what you're going to get".
 * Some Time Lords have more control of their regeneration. The Doctor does indeed often have a difficult time with regenerations, but he also tends to regenerate in extremely traumatic and unplanned situations - notably, while about to die. Romana is not shown to be in a traumatic situation, and therefore should have an easier time controlling the process.


 * When the human slaves are being exterminated in order to make the Doctor surrender, the woman slave stands perfectly still and shows no reaction during her extermination; even after the negative-effect fades, she remains standing upright before throwing herself on the floor, in a very unconvincing manner.
 * She is shot, then slowly falls to the floor. This is consistent with how people usually die when standing up.


 * During a countdown the Daleks count in seconds.
 * This is a standard occurrence in many Dalek stories, however the Daleks may have been counting using their own measurement of time, making this a simple translation of convenience.


 * At the end of the story Tyson says that Davros is being taken away to stand trial for his 'crimes against humanity'. But with the exception of Sarah-Jane Smith and Harry Sullivan (See Genesis of the Daleks'), Davros has never encountered a human before. All his crimes were committed against his own people centuries ago.
 * He knowingly created the Daleks with the specific intent that they should strive to become masters of the universe and conquor all other forms of life. Therefore, he can be held at least in part responsible for the terror and destruction they have caused for humanity since then. In any case, Tyssan's actual words are "crimes against the whole of sentient creation" (although Tyssan himself, as a human who has recently been enslaved and brutalised by the Daleks, has every reason to personally resent their unrepentant creator.


 * If the Daleks believe that self sacrifice is illogical ergo impossible, what is their rationale for the "Blakes Seven" inspired scene in which they shoot the hostages in order to force the Doctor to surrender?
 * As Davros indicated to them, the Doctor is not "logical" in that way. They realise he will surrender Davors if they threaten to kill more hostages.


 * In episode one, the Doctor stresses to Romana the need to continually take the anti-radiation pills. When Romana is captured by the Daleks, she is unable to take another dose. However, the missed doseage does not seem to affect her health
 * Her collapse in the mine seemed to have been part of her act, to deceive the Daleks into thinking she was dead.
