History is written by the victors. Or, in this case, the corpse-monks with a flair for propaganda.
Short Synopsis
The Monks have rewritten Earth’s history so that everyone believes they’ve always been in charge. The Doctor appears to be siding with them, Bill tries to snap him out of it, and the only way to defeat them is to overwrite their lies with a stronger truth. Spoiler: Bill’s memory of her mum saves the day.
Extended Storyline
Six months after Bill accidentally invited the Monks to rule Earth (thanks, blind Doctor + desperation), the planet is unrecognizable. Streets are plastered with giant posters of skeletal monks. State-run broadcasts constantly remind people how lucky they are to live under benevolent, corpse-faced overlords. It’s like 1984, but with more hoods and fewer moustaches.
Everyone believes the Monks have always ruled Earth. Always. History has been rewritten in one big gaslighting operation. People who remember otherwise are arrested as “dangerous heretics.” (Basically, if you’ve ever argued with your uncle about politics on Facebook, you already know the vibe.)
Bill, however, remembers the truth. Why? Because her bargain with the Monks was personal — her consent powered their rule. So she alone can resist their rewritten reality. She clings to memories of her mum to keep her sanity. She lives with an imaginary version of her mother at the kitchen table, narrating her day to her. It’s heartbreakingly sweet — and the only thing keeping her grounded.
Determined to fix her mistake, Bill sets out to find the Doctor. When she finally does, the reunion is not what she expected. The Doctor appears to have sided with the Monks. He parrots their propaganda, insists they bring peace and order, and basically sounds like he’s doing PR for Space Stalin. Bill, horrified, argues with him.
Then comes the gut-punch: the Doctor calls soldiers into the room… and declares Bill a traitor. Bill, panicked, pulls a gun and shoots the Doctor. He regenerates — golden energy sparking, everyone gasping. Except… surprise! It was a test. The “regeneration” fizzles, the soldiers laugh, and the Doctor smugly reveals he was faking it all along to test Bill’s loyalty. (Because apparently traumatizing your companion is the best way to say, “I trust you.”)
Now on the same side again, the Doctor, Bill, and Nardole set out to break the Monks’ hold. The key lies in their broadcast system: the Monks beam their rewritten history into everyone’s minds from a central pyramid. To stop it, someone has to overwrite the Monks’ lies with a stronger truth — a memory powerful enough to break through mass brainwashing.
The Doctor tries. He sits in the chair, connects his mind, and floods humanity with his truth. But his truth — abstract ideals, logic, defiance — isn’t strong enough. The Monks just shrug it off. For once, his speeches fail.
Enter Bill. She takes the chair, ready to sacrifice herself. She pushes her strongest memory into the signal: her mum. Her love for the mother she never knew, but whose photos she treasures, becomes the anchor point. Bill’s truth overwhelms the Monks’ lies, breaking their grip. Humanity wakes up. The Monks, having lost their influence, quietly pack up and leave. (No dramatic fight, no destruction — they just slink away like failed cult leaders.)
Earth is free. Bill saved it — not with weapons, not with strategy, but with love and memory.
The Doctor, ever the grumpy optimist, delivers a final moral: humans are resilient. Sure, they’re easily fooled by propaganda and lies, but they always bounce back. (Which is his polite way of saying: “Well, that was stupid, but you’ll muddle through.”)
