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

You are exploring the Discontinuity Index, a place where any details or rumours about unreleased stories are forbidden.
Please discuss only those whole stories which have already been released, and obey our spoiler policy.

This page is for discussing the ways in which The Witch's Familiar doesn't fit well with other DWU narratives. You can also talk about the plot holes that render its own, internal narrative confusing.

Remember, this is a forum, so civil discussion is encouraged. However, please do not sign your posts. Also, keep all posts about the same continuity error under the same bullet point. You can add a new point by typing:

* This is point one.
::This is a counter-argument to point one.
:::This is a counter-argument to the counter-argument above
* This is point two.
::Explanation of point two.
::Further discussion and query of point two.

... and so on. 

• 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.
