Judging from this, no,
Mrs. Flood and the Rani (Archie Panjabi) are vowing to give the Doctor absolute terror…by being a family man.
He’s married to Belinda and have a daughter named Poppy.
Where’s the terror? Keeping him in this illusion so the Rani can destroy the world, as ordained on May 24th.
However, one person is suspicious.

SPOILERS BELOW

It begins in 1865 Bavaria, where the Rani takes a newborn from a man who was a seventh son of a seventh son. The kid is, indeed, his seventh son. It may be too special because when the Rani kisses the baby she turns the family to violets and birds.
So, what’s the endgame for the Rani, aside from erasing the Earth?

Cut to May 23rd, and it’s an England that doesn’t exist. The Doctor is married to Belinda, and they have a daughter named Poppy (who is really Poppy from Space Babies). Conrad is apparently the BBC, reading stories from a book and giving the weather.
UNIT is now an insurance company, where the Doctor (now John Smith, a familiar alias) works. They’re excited about May 24th, which may be the ultimate holiday

What about Ruby Sunday (Mille Gibson) ? She sees the Doctor but he doesn’t remember her. Then we see Mel (Bonnie Langford), and Smith tells her not to talk to Ruby. Also, sometimes a dish or cup breaks while no one is looking. There’s a reason why.
What’s apparent is that everyone accepts this reality, not asking about the walking dinosaur skeletons or the Bone Castle where the Rani and Conrad are.
If anyone doubts, they are reported. Sounds like basing reality on Fox News.
Yet when Belinda can’t remember giving birth to Poppy, she runs from the house and screams.
Remember when she was supposed to be like Tegan, insisting every week to go home? This may be a fake reality, but it’s not a good luck for her. If she winds up defending Poppy by any means necessary, it would be a great comeback.

Ruby is able to recognize Shirley (Ruth Madeley) from UNIT She also finds a group of people who are left out of the fake reality because they are just ignored. They also say there are leftovers of the Earth That Was. Maybe the Rani figures the poor, disabled and imperfect can’t beat her. She does make sure people who doubt are scorned, though.

I thought Archie’s portrayal of the Rani was a little over the top. I think the previous Masters, if they could, would have advised her to tone it down. Maybe it shows she is certain her plans can’t be stopped. She’s letting Conrad (Jonah Hauer-King) tell everyone about her relationship with the Doctor, although it’s really biased against him.
Still, she’s no Kate O’Mara. She was able to pretend to be Mel when Seven awakened.

When Conrad talks to Flood, he wants to be assured he is making a better world, or his idea of it. If he suspects that he wasn’t, would be arrested for having doubts?
Eventually, Smith (the Doctor) starts to see something is amiss when he sees this:

Yes, it’s Rogue (Jonathan Groff) in a Hell dimension, and he can only say one thing, “Tables don’t do that”.
He means the cups are going through the tables and breaking. Smith starts to have doubts, which causes Belinda to report him. However, both are arrested, since Flood is now chief of police.

This is all to allow the Rani to humiliate the Doctor. Again, she goes over the top, and claims they both danced while a place called Persephone burned. That might not be true, since she said this while he still thinks he’s an insurance agent. She also tells Belinda she never had a daughter.
Once the Rani reveals herself, to the Doctor’s horror, she explains the child is really the God of Wishes. That’s how she eliminated the family and helped Conrad remake the world in his own opinion. It seems the baby is part of the Unholy Trinity while Conrad just plays a supporting role.

The Rani’s endgame is destroying the Earth by causing enough doubt in the reality she made. By making the Doctor also doubt the reality, it completes the Earth’s destruction.
Why? She wants to release something from the Underverse, someone she and the Doctor know all too well…
the first Time Lord, Omega. He was last seen in “Arc of Infinity” but now the Rani wants to use his body to rebuild Gallifrey. If it means erasing the Earth, so be it.

It’s interesting the Doctor regains his memory just in time for the Rani to kill him, hurtling him down the Bone Castle. As for Belinda, her existence is erased. This happens while the Earth literally falls apart.
Yet the Doctor says “I have a daughter. Poppy is real.”
What? Isn’t she a toddler space captain?

It looks like all is lost. Yet in the previews, it seems some part of Earth survives, The Rani is still certain she’ll win, and there doesn’t seem to be anything to stop her.

Belinda is somewhere, though, determined to get Poppy back. And could there be someone who can stop the Rani…like someone’s granddaughter?
It’ll be a long week.
