Theory:Doctor Who television discontinuity and plot holes/The Witch's Familiar


 * how did Davros get the confession dial? how did it end up in a box along with the sunic-glasses (yes, I just coined a phrase)
 * Davros states that Colony Sarff confiscated it.


 * How did the Doctor a)get control of Davros' chair? b)manage to fit in Davros' chair?
 * a) probably by force b) why shouldn't he?


 * The Daleks understood what "mercy" was in their very first chronological story, Genesis of the Daleks (TV story).
 * Did they? Here's a direct quote from a Dalek in that story: "“Pity? I have no understanding of the word. It is not registered in my vocabulary bank”.


 * Was there any explanation as to why pre-Time War series model Daleks were in this (and the prior) episode?
 * Davros likes the classic designs?
 * Rescued from the Asylum?
 * Perhaps the Daleks repaired some of the city's old production lines when they rebuilt the place.


 * What caused the explosion in the sewers after Missy attacks the Dalek guard? The casing is perfectly fine afterwards when she stuffs Clara inside.
