Theory:Doctor Who television discontinuity and plot holes/The Magician's Apprentice


 * Moffat's attempts at being PC blow up twice. First we see Black men on what is revealed to be Skaro. Where Davros is. Davros is a Kaled, people known for their NAZI-like racism.
 * The only racism they ever showed, was towards the Thals (and the mutants) who they had been at war with for a thousand years (and going by the hints in the first episodes, its likely they started it). The idea that all Kaleds are white has never been suggested, nor is their any reason to assume they would care about race in their own species. Especially as by this point they are near the end of the war, and down to around one city left. If they are so desperate they recruit children for battles, who would honestly care about whether you were black or white?


 * And then in Essex 1138, there are very clearly Black people among those watching the Doctor playing the electric guitar, standing next to a tank. Of the three, the leats likely one is actually the Black people in Essex in 1138.
 * Um, their actually were black people in England during the middle ages, not many sure. But they did exist, many came over with the Romans during the invasion or settled their during the occupying period. Others (such as Moorish traders and mercenaries) came over at different periods. Legitemently concepts such as racism didn't really become mainstream until the slave trade.


 * If Davros has had the sonic screwdriver his whole life, why have we never seen him use it before?
 * Have we ever seen him in a situation where it would have come in handy? Also, it's very possible that he would have no interest in a device that doesn't kill, wound or maim, especially by the time we meet him in Genesis.


 * How did the Daleks know where to find the Doctor, and thus who to convert into a Dalek puppet? Isn't Coloney Starf wasting his time hunting the Doctor if the Daleks already know where he is? And if they have Bors there, what's to stop him from stunning the Doctor and transporting him like in Asylum?
 * Its possible he was infected by the Coloney's snake that strangled him.
