However let's not forget the beautiful yet terrifying Missy. Oh how you have stolen the show Missy. I feel drawn to this version of the Master in a similar way I did with Riversong. She's such a wonderful character to pop in and stir the pot to keep things moving. As I've said it before and I'll say it again; Clara is done. The story is over. We need to move on. Missy is keeping this series alive.
This episode opens with Clara still alive and hanging by her feet by a rope tied by none other than our favourite bad-girl; Missy. Our unlikely duo discuss how the Doctor always comes to victory and head off on their own adventure on Skaro. After finding their way into a sewer, Missy breaks the news to Clara that, in the language of the Dalek's, sewer and graveyard have the same meaning. Meaning of course that the walls are covered in decomposing Deleks that can never die.
Missy uses her brooch which she says is Dark Star Alloy, to kill a Delek, but not before she offers up a small piece of history. The brooch was a gift from the Doctor when Missy's daughter ... I guess will find out the end of that story another time.
Missy's plan is Clara the Dalek. De ja vu? After hooking Clara up inside a Delek, we learn that exterminate replaces so many phrases, such as I love you, and you are different to me.
Welcome to the episode Peter Capaldi! After hijacking Davros' Delek-Wheelchair, he swans into the center of the Delek base with the best one liner of Capaldi so far: 'Admit it, you've all had this exact nightmare'. However it is during a heartfelt and unusual conversation that Davros tries to convince the doctor he is asking the same question of himself that the Doctor has been asking since his regeneration into Capaldi: 'Am I a good man?'. Sucked in by Davros, the Doctor sees Davros-Child scared and alone within his enemy; the child we still don't know if he saves in the past. But it's all a trap of course, and a very good one at that.
The episode itself offers classic Moffatt musings with a long compassionate speech from Capaldi and some great analogies on Davros' behalf. The Doctor admits to Davros that Gallifrey has not been destroyed, and this information becomes the crux to Davros' trickery.
Falling for Davros' trap, the doctor decides to omit some regeneration energy into Davros' life support but of course, Segway Man is there to trap the Doctor so Davros can steal as much regeneration energy as possible. After being saved by Missy, the Doctor let's Davros in on his little secret that he knew it was a trap all along.
The Doctor comes to a face off with the Clara the Dalek as is convinced by Missy that Clara is dead. (Oops...Missy you are in the bad books now!) However after begging from inside the Dalek, Clara manages to use the word Mercy which raises the question: How can a Dalek use this word?
Back at the site of Davros-Child, the Doctor exterminates the hand-mines and saves the boy and tells him that enemies and friends aren't important but mercy is, setting up Clara's escape in the future.
So what did we learn from this episode? Most of all, Missy is the glue to this series. She's a fresh story line within a tired companionship. More importantly, the Sonic Screwdriver is now a pair of Ray Bans, convenient for the new grunge look of the Doctor.
Excuse me while I invest shares in Ray ban.
