Doctor Who 13.5 "Survivors of the Flux"

Beginning with the Doctor (Jodie Whittaker) being transported to the ship with the woman who reveals herself to be Tectuen (Barbara Flynn) who looked after her.  Taking her from the planet and wiping her memories storing them in a pocketwatch.  The Doctor angry she was taken she might have been waiting for someone to come for her.  She explains about Division and then we get the Great Serpent/Prentiss (Craig Parkinson) going from time to time and establishing his grip on UNIT.  Starting with the Grand Serpent ending up at a country estate and gets a job with the man who was behind UNIT, Farquhar (Robert Bathurst).  But as said, he disposes of all of them. Where Kate Stewart (Jemma Redgrave) says she sees through Prentiss and won't let him get away with whatever he's planning.  She becoming his next target and having to go on the run.  Apparently the Doctor's transformation to an angel was only temporary and just to get her to the ship.  It's Division HQ.

Meanwhile Yaz (Mandip Gill) Dan (John Bishop) and the Professor (Kevin McNally) jump from 1901 to three years into the future looking for a pot.  Later it's revealed the Doctor left her a message as a hologram, which she knew Yaz would find and would be opened for her when they are separated and she sends her on this quest to find a date and time for when the Flux will attack Earth again, thus the pot.  That's since the Doctor knows that Earth being the only planet being left intact will be marauded by other species and taken over.  

The scenes with the three of them were very Indy Jones, The Mummy.   Overseen with assassins as waiters as Yaz notices the serpent tattoo on his wrist as he takes a cyanide capsule to prevent questioning.  Being told that they need to fetch a dog.  Of course being the Lupari Karvanista (Craige Els) so they leave a message on the Great Wall of China which can be seen from space, "Fetch Your Human" ie Dan.  The Lupari already having problems with keeping a ship in formation and not being able to protect Earth.  However he commandeers the ship and ends up finding Bel (Thaddea Graham).  Having a battle with his weapon which was very much out of Stargate.  As was the snake-like creatures which left the mouths of the Grand Serpent's victim's mouths and attached onto him.

However Wiliamson turns up in their cabin and Dan recalls him.  They finally get to his tunnels and Yaz comes right out asking him what's going on.  Vinder (Jacob Anderson) ends up on a planet where he meets Diane (Nadia Albina) after he's transported into a Passenger.  As well  as finding that Swarm (Sam Spruell) and Azure (Rochenda Sandall) have taken people and are using them as power sources.

The Doctor finds out that Division became a shady organization pretty much running everything.  That's why the Flux was released.  So that they destroy everything so the Doctor can't go round saving planets and universes.  Could say justice finally came round full circle as Tectuen is destroyed by Swarm just as the Doctor needed to find out more from her about her past regenerations.  Eyeing the pocketwatch which Azure sees her doing.  Agh couldn't she have just gotten the watch somehow, that would've been too easy obviously.  The Sontarans make a pact with the grand Serpent and end up in the tunnels, as well as on the Lupari ships.  

Would Division really destroy so many planets and the universe just to keep the Doctor in check or to stop her doing what she does.  Then what of UNIT?  So many questions unanswered like what happened to Poppy?  How did the three get to travelling and away from the village.  How did UNIT get hold of the TARDIS?  Why did Swarm say Division imprisoned him and at the same time why did he escape?

Also the Doctor never got a chance to confront Tectuen in more depth or ascertain the real motives behind her becoming the Timeless Child.  In the end eps did end up being a bit scattered all over the place.
