While I’m not planning to go into a lot of plot details, it’s likely that the random mutterings that follow will reveal some things you might prefer not to know if you haven’t seen the episode yet, so in my usual way, I’ll include this warning:
Well, wasn’t that fun? More misdirection than a very misdirected thing directed by a particularly devious misdirector. Yes, I’m looking at you, Mr Moffat. Well played, sir. From the beginning of this year’s series, we’ve been getting odd glimpses of a strange woman who calls herself “Missy”. Think of a creepy version of Mary Poppins for the image, and you’ll be about right. Somehow, people who’ve been killed while associated with the Doctor find themselves in her environment. Is this some kind of bonkers afterlife?
Anyway, this story started with the death of Danny Pink, Clara’s boyfriend and teaching colleague. Clara, being a bit
unhinged upset about this, tries to force the Doctor to bring him back. Being at least as devious as she is, he works around her devious plan, and tries to help her anyway.
And then it starts getting insanely complicated. As I mentioned last week, it’s a shame that the presence of the Cybermen in the story couldn’t have been kept secret, but this was more than made up for by the successful (as far as I was concerned, anyway) suppression of Missy’s true identity. OK, you have been warned about spoilers, so I’m not going to hold back.. What a joy to have the Master, err, Mistress, err, Missy back. It’s much more fun to have an antagonist for the Doctor who is (a) seriously evil, not just misunderstood and (b) madder than a bag of mentally disturbed crazy things. As always, she’s got a Terrible Plan which involves creating a huge new army of Cybermen which grows by a really nasty means….
Though of course, her plan is worse than that. Merely conquering the universe is far too small for Missy. No, she wants the Doctor. Wants him to run her army. Wants him to be the one to take over the universe.
Of course, this doesn’t quite work. As always,
the Mas Mistre Missy’s plan falls apart, thanks to the Doctor’s friends. Or mostly thanks to someone who isn’t really his friend at all…
All good fun, and ending with some nicely unanswered questions. Clara and the Doctor have both lost something, and neither will tell the other. So it’s probably just as well that the Doctor gets an unexpected visitor. In the Tardis. A visitor who will probably cause anyone who objected to the Robin Hood episode to have a brain meltdown…
And that’s your lot until Christmas!
 It would have been a challenge to memory-wipe all the people who saw them being filmed in London and Cardiff
 And just for once, this one is Terrible and not just bad and guaranteed to backfire
 This was just subtext with her last incarnation and the tenth Doctor, but quite blatant here
