Doctor Who fans think they have figured out the shocking twist in the season finale as the Doctor faces off against The Rani.
The two-part finale kicks off with Wish World on Saturday as Mrs Flood (Anita Dobson) and The Rani (Archie Panjabi) enact their plan that will destroy the Earth on May 24 (as ominously delivered by a holographic Graham Norton).
Lucky Day conspiracy theorist Conrad (Jonah Hauer King) has been recruited to join their nefarious schemes and we know there is still one more foe lying in wait to complete this Unholy Trinity.
When Mrs Flood revealed her true identity during the mid-credit scene after The Interstellar Song Contest and bi-generated, she quickly fell in step behind Archie Panjabi’s ‘upgraded’ version.
And in a sneak peek for the new episode we see Mrs Flood continue her servile persona as The Rani’s punching bag after she quips that the imagery of being sprung from Mrs Flood’s loins is the ‘most disgusting thing she’s ever heard’.

Now, up until this point, Mrs Flood has shown her nefarious side (lulling us into believing she would be a key nemesis at the end of this season).

Whether through her terrifying speech to Cherry at the end of season one or her conniving plans to release Conrad from jail – plenty of fans have expressed their surprise at her sudden change in demeanour.
As such, some Whovians believe we’ve not see the end of Mrs Flood’s scheming and, provoked by The Rani’s dismissive attitude, she’ll turn against herself in a last minute twist to bring down her counterpart.
In one theory posed by Reddit user Slight-Ad-4442, they wrote: ‘We’re all thinking that the new Rani is the evil one, but perhaps that’s the point. Mrs Flood seems like a nice old lady but really is the more ruthless of the two.’

And then took the theory further, adding: ‘Turns out that Mrs Flood has a little bit of the Rani evilness in her, but a lot more goodness in her. She will betray the Rani in favour of her own survival or saving Belinda.’
And it was speculation backed up by other fans who see the same trajectory for her.
‘I totally see either one of The Rani’s betraying the other!’ Gold_Warning_3099 agreed.
‘The two Ranis betraying each other seems on point. Different incarnations never seem to get on that well, plus the Master/Missy combo was already them killing each other. These kind of ideas tend to repeat,’ Caacrinolass pointed out.
Over on X, users had the same idea, although the jury seems to be out on which exactly how the betrayal will go down if the theory pans out.
‘I’m putting money on it now, Mrs Flood will betray the Rani, especially with how much they’ve set up this hatred the Rani has for Mrs Flood already haha,’ @whoronomy posed.
‘Calling it now, Mrs Flood is gonna turn out to be the evil one and The Rani will have to help The Doctor,’ luisthegardener said.
‘I think Mrs. Flood is purposely messing with the Rani,’ twistedtardis declared.
Russell T Davies has opened up a bit more about the dynamic between the pair.

‘What you get now is the two Ranis working together. Mrs Flood is still calling herself Mrs Flood. As viewers saw at the end of episode six, it’s a fantastically servile relationship where she sort of becomes the Igor to the Rani’s Frankenstein,’ he told the BBC.
And added: ‘It’s a delightful partnership. It’s really fun, and very powerful. The Doctor is immediately up against two enemies instead of one.’
Everything will come to a head in the final episode of the season, The Reality War in which ‘battle rages across the skies as the Unholy Trinity unleash their deadly ambition.
‘The Doctor, Belinda and Ruby have to risk everything in the quest to save one innocent life.’
Doctor Who returns this Saturday with Wish World on BBC One and BBC iPlayer.
