I almost don't know where to start with this final episode because there's so much that needs unpacking. On top of it all, Moffat had me all up in my feelings with his delicate balance between humor and impending doom. We had dueling timelords and masturbatory Masters. It was all too much and just enough at the same time.
The overarching question this season seemed to center around whether or not Missy could be redeemed. The Doctor and the Master have known each other since childhood and Missy, is the only one really capable of being the Doctor's ever lasting companion because while the Doctor's human companions can spend the rest of their lives with him, he cannot spend the rest of his life with them. This is even more true now that the Doctor potentially has unlimited regenerations. World Enough and Time was supposed to be Missy's test run at being good but it all runs into a wall when she meets the Master.
I must admit that Missy and the Master played off of each other so well. Until the very end we didn't know exactly where Missy stood. Her two hearts were pulled between her previous incarnation and her life long frenemy. John Simm's Master continued to throw in just the right amount of nasty, teasing Bill about being a cyberman and the role he played in that change, as well asking her for a bra, in reference to his own upcoming regeneration. John Simm's Master is evil because he can be and even when it leads to the revolt of an entire population because of the cruelty of his headship, he sees no reason to change, only a reason to move onto something new.
Throughout this entire episode, we were continually reminded of just how great an actor Peter Capaldi is. I'm going to miss him so very very much. When the Doctor gave an epic speech explaining that he does what he does not for attention or accolades but because it is the right thing to do, I found myself completely drawn in. Missy, who has been struggling to change was clearly conflicted but of course, the Master didn't give a damn whatsoever about the Doctor's appeal to the better angels of his nature.
When the final stand between Missy and the Master occurs, it's quickly clear that it could not have ended any other way. Missy killing the Master was perfect and stealthy, just the way that you expect Missy to act. When Missy declares that it's time to stand with the Doctor, we know in this very second the Doctor has won and that he will finally have his eternal companion. Naturally this cannot be allowed to stand and so the Master destroys his own future redemption by killing Missy and making it clear that she shouldn't even bother to try and regenerate. The Master absolutely refuses to stand by the Doctor. The Master may be fascinated by being a Time Lady but he's only wiling to allow himself to go so far. It makes me wonder if Missy's change of heart is about her experiences with the Doctor, or if the change in gender between the Master and Missy was simply enough to change her outlook on life and the universe? It makes very little sense for the Master to kill Missy, knowing that he's about to become Missy himself. It shows the level of his unwillingness to bend. I am absolutely going to miss Michelle Gomez as Missy.
