"You have wisdom," says Cyber Leader. "If the Doctor is planning to intervene, then the Ascension will commence immediately." Mr. Cole, Mr. Scoones, Mr. Fetch and Mr. Milligan are summarily electrocuted at the pull of Mercy's lever, and she smiles at their fall. It's nice, for a moment, but then she goes into the other room and starts shouting at the kids about the Industrial Revolution like a steampunk Ru Paul all, "I wanna see you work!" so they turn wheels, and carry water, and there are pieces of coal that are as big as their heads, and like, steampunk is kind of a bummer right now. Little kids, working their fingers to the bloody bone. That's kind of amazing on Christmas.
"Soon the CyberKing will awake," Cyber Leader reiterates for no reason, and Mercy takes his arm, asking to be shown his throne. Watching a hot lady take a Cyberman's arm, like he's her escort in to dinner, is pretty awesome too. Less so is how the Cybermen keep automatically detecting Jackson and the Doctor and Rosita no matter what they do. Something happens with some stupid Dalek thing, I don't even care anymore, it's some kind of Dalek machine of some sort, because what on God's earth can't be vastly fucking improved by throwing a billion Daleks at it. So the Doctor breaks part of it off or something, and just says Dalek Dalek Dalek like a million times and runs around with his hair going crazy, and there's much talk of electricity and percentages of this and that, and what happens when the... Mathmath Dalekdalek Cyberthing. Come! On! Little kids doing forced labor, steam and clockwork machines, insane hooker headmistresses? Don't lose me now!
So the Cyber Leader conducts Mercy to an ever-so-steampunky drawbridge, and it's magnificent, and on the other side is an even more magnificent thing that Mercy likes to a throne even though it's obviously a total electric chair because Mercy doesn't get it, still, that the Cybermen don't really have aristocracy or kings, just an electric chair to kill you with or a Dalek device to bore you with, and anyway, there's no such thing as royalty in a race of robots that run on pure Cold War Communism. Mercy congratulates Cyber Leader on being the cyberfuture CyberKing and he's like, "OMG this is so embarrassing because now we're going to take out your brain and stick monster in your ears and turn you into the pilot of a giant fucking robot," and she's like, "I'm fairly certain I asked you about that, and you said no," and he's like, "Yeeeaaaah. We lied?"
