Potential villains
- Sontarans are confirmed, and are back to their classic appearance too. Maybe Rutans could show up too.
- Rutans don't appear, but the Sontarans do mention that they will not ally with the Rutans in the wake of the Flux.
- Weeping Angels are confirmed.
- Ood are confirmed.
- Not as a major villain: one Ood acts as Tecteun's servant.
- Cybermen are confirmed yet again.
- Not as a major villain.
- Daleks will be back. In a completion to a Dalek Trilogy the Resolution Dalek will have a backup of themselves.
- Confirmed that Daleks will be back, including in the New Year's Special.
- The Master, as Chibnall seems to have set him up as the Arch-Enemy of Thirteen, and he never really dies.
- Seems increasingly likely, given the name drop in the finale.
- Confirmed.
- Tecteun, who will turn out to be Not Quite Dead and continue the conflict from The Timeless Children.
- Confirmed.
- Rassilon/Omega, with their part in the Timeless Child being revealed.
- The Valeyard, who could be tied to the Timeless Child somehow.
- Silurians, since Chibnall has done stuff with them before. Maybe they could appear alongside the Sea Devils in "Legend of the Sea Devils."
- Jossed in that no Silurians are in Legend of the Sea Devils.
- Stenza, who felt like they were going to be more important than they actually were in Series 11.
- Zygons, with there being some chaos with them since UNIT is gone.
- Looking more likely now that Kate Stewart has been confirmed to appear in "Survivors of the Flux."
- Drahvins. Since they're a misandrist species, having them deal with a female doctor would be interesting.
- Jack Robertson. It's Thirteen's swan song, and he has met her twice.
- Sea Devils. The second special features Chinese "pirate queen" Cheng I Sao, so presumably there is a lot of action out at sea, with the Sea Devils acting as antagonists.
- Confirmed
- The Myrka. A vaguely similar sea monster is seen in the trailer for "Legend of the Sea Devils".
- Jossed. The monster is called Hua-Shen and is very different from the Myrka.
- Ashad. A similar damaged Cyberman can be seen in the centenary special trailer, and his reappearance would please the people who felt he was wasted by his early death.
- The Cybermasters.
- Confirmed
The Skull-Faced character in the trailer is...
- The Master, a la The Deadly Assassin.
- The Ravagers.
- Confirmed.
- The eponymous Flux
- Some kind of Halloween-themed villain, judging from the title "The Halloween Apocalypse."
- Confirmed, in a sense; he's the "Swarm" that was hinted at early in production, and while he doesn't do much in the "The Halloween Apocalypse", he is present in it.
Swarm and Azure are...
- Ravagers
- Confirmed.
- The same species as the Doctor's (Timeless Child's) original species
- The Doctor's siblings
- The Doctor's parents (or at least they may claim to be...)
The Flux is...
- An event which is changing history, things like Sontarans in the Crimea War.
- An organisation.
- The Valeyard (Someone had to say it)
- The Big Bad who want to capture the Doctor
- A Negative Space Wedgie that'll wreak havoc on time, space, and causality. And it'll look like the churning gray-and-purple fluid that's been shown in the opening credits, all through Thirteen's tenure.
- The former now seems to be confirmed!
Planet Time is...
- Gallifrey.
- Rebuilt after its sterilization by the Death Particle.
- In the past.
- In an alternate timeline/universe.
- Jossed, as the Division, who are of Gallifreyan origin, were sent on a mission there and seem to be unfamiliar with it.
- The planet where the Timeless Child was found.
- Thus, the Temple of Atropos was the building the child was found near.
- Likely jossed as the exterior of the Temple of Atropos differs markedly from the momument the Timeless Child was found near.
- The planet where the Timeless Child originated (which may or may not be the same place where she was found)
- Jossed; it is mentioned in Once, Upon Time that the planet was a "construction" by the Time Lords.
- Some kind of Time War abomination.
- Jossed, as the Temple of Atropos is contemporaneous with the Division and Ruth!Doctor, which pre-date the Last Great Time War.
- Replacement overseers for time following Gallifrey's exit and subsequent destruction.
- Jossed, as the Mouri and the Temple of Atropos are contemporaneous with the Division and Ruth!Doctor.
The Timeless Child and the Mouri belong to the same species.
The Mouri and the Weeping Angels are related.
Both are quantum-locked beings to do with the passage of time.- The Mouri are precursors for the Weeping Angels.
- Weeping Angels are fallen Mouri.
- This is looking highly possible considering that "Village of the Angels" has confirmed that it is possible to convert Time Lords into Weeping Angels.
Passenger is...
- Dan's friend Diane or what's left of her after Azure has had "fun" with her.
- Apparently Passengers are interdimensional prisons, the purpose of which is still unknown. Diane is in a Passenger, but she is not a Passenger herself.
Swarm and his crew were not defeated by a past version of The Doctor while he/she was with The Division
The battles that Swarm muses about are actually still in The Doctor's future. Note that he recognized Yaz and Vinder and knew personal details about them, like the mantra abbreviated on Yaz's palm and Vinder's disgrace for leaving his post as it was swallowed by The Flux. Perhaps they were/will be with The Doctor when she lays the beatdown on him and locks him up in the middle of nowhere at the beginning of time.- Jossed — The Doctor took them down back when she was working for The Division.
The Master will return and pull a Hijacked by Ganon on Swarm
- Perhaps he’s behind the Flux, or is working with Swarm but planning to betray him. Or maybe the Master just won’t tolerate some random guy wanting to be the Doctor’s nemesis.
- Looking jossed. The Ravagers work for Time itself, and Time seemingly warns the Doctor about the return of the Master, suggesting they aren't on the same side.
The theory that Weeping Angels are all derived from Time Lords, popularised since "The End of Time", will be fully confirmed.
- Perhaps this could be combined with the above theory to have the Master survive his apparent death by turning into a Weeping Angel.
Kate Stewart and Osgood are now rogue alien hunters
- Just immediately bringing back UNIT would remove the weight of its shutdown in Series 11, so they will now be vigilantes. Perhaps after their actions inn this episode, the British government will see reason and will bring back UNIT.
- According to Time Fracture, they’re still operating, at least in an unofficial sense.
- Confirmed that Kate has gone rogue at least, fleeing the Grand Serpent's assassination attempts. The next episode confirms that she's fighting against the Sontarans.
Swarm and Azure are, respectively, versions of the Doctor and the TARDIS.
- Azure is a synonym for "blue" and is Swarm's faithful companion. Swarm's prison bore similarities to the Pandorica. Passenger, which seems related to both of them, is in some fashion Bigger on the Inside.
The Division, contrary to what we have previously been told, is not an organisation founded and controlled by Time Lords.
- "The Division" (or simply "Division") is really a force/organisation with greater power than the Time Lords, which recruited/influenced the Time Lords into working for them.
- This explains their dominion over "every species".
- It was founded by the Timeless Child's species/civilization.
- Alternately, "Division" is the name of the portal which the Timeless Child was found beside, or at least, they created that portal.
- Jossed, it is in fact an organization controlled by the Time Lords, though they were authorized to break the laws of time and they have since left the universe.
At least one of Bel and Vinder is Gallifreyan.
- They talk about having lived in "a cubicle hotel opposite the Academy".
- Vinder is the one who attended this "Academy", but it is unlikely he is Gallifreyan as the Doctor has been shown dropping Vinder off at his planet, which was ravaged by the Flux. Surely, the Doctor would have noticed if it had been Gallifrey, and Gallifrey had been destroyed by the Death Particle by then.
- " The Academy" is far too generic a term to link it solely to Gallifrey — remember how Luke was asking Uncle Owen about transmitting his application to the Academy?
- I suddenly hear the sound of a hundred fanfics being typed, scribbled, and dictated....
The army moving in after Medderton's populace disappeared was UNIT
- They have been keeping custody of the Weeping Angel Doctor.
- Jossed but they did collect the TARDIS in 1967 and kept it until 2021!
The Williamson Tunnels...
- ...are linked to the Temple of Atropos.
- ...are linked to the tunnels Yaz, Dan and Jericho are investigating in 1904.
- Confirmed. They are also transportation through time.
The Flux will be the pretext for another major Cosmic Retcon
- Whilst it seemed apparent given the change of showrunner, now we know that the Flux has far-reaching consequences across time and space, it seems almost inevitable there will be many changes to the Whoniverse even when things inevitably get set right- Close-Enough Timeline, perhaps?
- However the core of who the Doctor is, including the "Timeless Child" thing, will not be subject to this retcon. The direction seems to be moving into further developing what this means for the Doctor.
- Seemingly jossed by the 60th Anniversary specials, which confirm that there was no Cosmic Retcon and that about half of the universe is still destroyed, and that the Timeless Child is still canon. However, the Toymaker apparently did muck about with the Doctor's personal history, potentially causing a similar effect.
The Grand Serpent is responsible for the UNIT Dating Controversy
- Considering he was trying to hide his eternal youth across the years, maybe he fudged the dates to conceal his deception.
- Confirmed, Kate mentions during their confrontation that he tampered with dates on various reports to help hide his lack of aging.
Tecteun wasn't killed off for real.
- Tecteun seems too important to kill off just like that, and this would also resolve the cliffhanger by revealing whatever Azure was doing was not fatal.
Yaz will exit as a companion by growing old and dying of natural causes in the 20th century.
- Jossed — the Doctor gets her into the TARDIS and they carry on their travels as normal.
Dan was a companion of a forgotten incarnation of the Doctor.
- Dan's remark that he once had a friend who had a bigger TARDIS is widely seen as just a joke, but it may actually mean something.
- Or perhaps he's met a different Time Lord, one fond of taking on a human and/or friendly disguise for long periods....
Door 9 of the Williamson Tunnels leads to...
- Gallifrey.
- The "rays of death" mentioned on the sign are the aftermath of the Death Particle.
- Alternatively, the door could lead to pre-Death-Particle, pre-destruction-by-the-Master Gallifrey.
- The Timeless Child's home dimension.
- The Division headquarters.
- The inside of a blast furnace, nuclear reactor, or other highly unsafe location on Earth.
The Master will return in the New Year's Day Special
And he will show up at the end of "The Vanquishers" as a cliffhanger.- Maybe it ends with the Serpent meeting the Master!
- Jossed in that the Master does not appear at the end of "The Vanquishers." However, he does seemingly get mentioned by Time in connection to the Doctor's impending death/regeneration. The Easter or Fall special might be more likely than the New Year's one, considering that the Daleks are once again the villains of the New Year's special.
The Serpent is Swarm...
- Hurled back in time.
Passenger will help save the Universe...
- ...maybe helping transport people within themselves. Or containing the Flux.
- Confirmed.
The Vanquishers will end...
- ...with a trailer for NYD and show the Daleks.
- Confirmed.
Tennant isn't playing the Doctor.
He is playing someone else (another Gallifreyan, maybe even a Time Lord, let's call him the Narrator) who goes to Donna and tells her of the Doctor\gives her memory back.- Jossed; Thirteen regenerates into a (very confused) Tennant at the end of "The Power Of The Doctor".
