The Witch's Familiar (TV story)

 was the second episode of the ninth series of Doctor Who produced by BBC Wales. It probed the reason why the Doctor had fled from Gallifrey and gave a needed explanation as to why Skaro had returned after it was shown to be destroyed in Remembrance of the Daleks, as the Daleks were said to have remade the planet anew. It also divulged how Missy had escaped her death in Death in Heaven through the use of a device to teleport away nanoseconds before she was shot by a cyber-converted Brigadier, which made it appear that she had been disintegrated.

This story was further notable for exploring several new narratives with Davros. It was the first time he was shown outside of his chair, and this revealed that he has no legs at all and both his spinal column and defunct left arm are a combination of robotic Dalek technology hooked into the machine. The episode also shows Davros turn off his eyestalk bulb and open his own eyes for the first time in all his appearances, and toyed with the possibility of him dying an indisputable death as well as him possibly regretting his actions.

In that same respect, the mechanics of a Dalek were given an in-depth look, showing how they control their casing functions, the weaponry and how their capacity for speech is filtered and conditions them so they must not utter anything which betrays their basic functions of hatred, as well as giving a rational explanation for why they repeatedly shout, "Exterminate!" in the bulk majority of their appearances.

In addition, having given the young Davros his sonic screwdriver and it wearing out with age, the Doctor decided against carrying around another screwdriver and instead revealed that he now has a pair of sonic sunglasses. The Doctor also lost a large portion of regeneration energy as well, resulting in the birth of a new hybrid race of Time Lord-Daleks. The long-term consequences of losing this energy are as of yet unknown. However, as the Doctor claims to been aware of Davros' plan, and to have let him take the energy as part of his plan to stop the Daleks, it is possible he prepared a way to prevent himself suffering consequences such as the loss of any regenerations, unlike when he last encountered Davros in his tenth incarnation, when he was forced waste a regeneration after being shot, creating of a Human/Time Lord hybrid clone of himself to abort the process before it could change his appearance.

Synopsis
As he's trapped in a terrifying Dalek city, the Doctor is without his sonic, and without his TARDIS and is all on his own.

Story notes

 * Missy is seen in a sewer, and pushes Clara down into it. Previously, in the Doctor Who spoof The Curse of Fatal Death also written by Steven Moffat, an incompetent version of the Master was shown falling into an absurdly vast sewer three times and taking three hundred and twelve years to climb out each time.
 * A dying Davros telling the Doctor that he wants to look at him with his own eyes is very similar to a scene in Star Wars: Return of the Jedi when Anakin Skywalker says he wants to look at his son Luke with his own eyes as he is dying, and, like Davros, has been hooked up to mechanical apparatuses after suffering crippling injuries, including a mask over his face as part of his Sith identity as Darth Vader.
 * On 27th September, the day after the episode's broadcast, the two-part opener was broadcast on BBC One and BBC One HD as one single feature-length episode.
