"Witch's Familiar" what an odd name for this episode, is the Doctor the witch with Clara as his familiar or is it Missy to the Doctor? I'm not sure but it was an exciting episode. Recap, Davros is dying and wants to talk to the Doctor. Missy and Clara have been exterminated by the Daleks in episode 1 but the opening scene in episode 2 has Clara tied upside down outside the Dalek compound with Missy saying how peckish she is then starts explaining how they're still alive. She tells a story about how the Doctor escaped death by using a similar trick.
Davros and the Doctor are talking, there's some dream sequence of the Doctor pointing a Dalek gun at the young Davros. Davros is spouting regrets and we see the Doctor eventually soften to the Dalek leader. We, as a viewer are soften to Davros's words, but we know where he came from and why he made the Daleks so we shouldn't be. Spoiler alert! The Doctor is not moved and in the end outwits Davros. It was a really good episode, I was taken aback by Davros's knowledge of the Doctors past and at the inference that he travels the universe to escape Galifray.
