This could make for a really nice "out" for the next writer to tackle the Master/Mistress character, given the way Missy seemed to be truly reforming, if they decide they'd rather have a true villain. Cybermen are known, above all else, for suppressing and eliminating emotions. Missy has started to feel sympathy, regret, hope....even if she eventually escapes the full conversion, and physically returns to normal, her emotions may be permanently damaged, turning her back into the evil sociopathic menace we've known and loved to hate!
- Looking Jossed given developments in the Expanded Universe. The February 2018 short story collection The Missy Chronicles ends with "Alit in Underland", a short story set during the two-week Time Skip in "The Doctor Falls" that follows the two Masters as they find a way to reprogram the Cybermen so that they will no longer be seen as targets for upgrading, which adds a new wrinkle to the events of that story. (The Doctor is unconscious during these events so he doesn't find out what they did.) In general, Expanded Universe works don't get to play with ideas that would be superseded by plans for the televised canon, so this would seem to rule out Missy being Cyber-converted.
- Also, another story in the collection ("The Liar, the Glitch, and the Warzone") reveals that Missy once encountered Thirteen without realizing it until it was too late. She's the curator Missy encounters in modern Venice who rescues the pickpocket kids Missy leaves behind in the past.
- ...or maybe the interesting encounter they'd had at the diner with said nice young waitress, a chatty young lady called Jenny who'd stopped in for a meal, and a cloud of sparkling, ghostly motes of light that kept drifting back and forth outside the windows.
- Jossed. Chis Chibnall claims that no old characters will be returning this season.
- Jossed: The new Doctor will have a trio of human companions, apparently from contemporary Earth. (Those who would like to see an Alit-as-companion story are directed to the aforementioned short story "Alit in Underland", which has her as a Tagalong Kid to the Masters.)
- The Daleks. They're a given at this point, especially in a new Doctor's first season, and even more this time out as they have not been the principal antagonists of a story since "The Magician's Apprentice"/"The Witch's Familiar" at the top of Series 9. Moreover, of the Big Three Whoniverse antagonists, they were the only ones who didn't get to be Season Finale antagonists in the Twelfth Doctor era (the Cybermen and the Master jointly held those duties in Series 8 and 10, and Series 9 went in another direction with the Time Lords' treachery turning the Doctor into a Woobie, Destroyer of Worlds for a while). It may well be time for them to be an Arc Villain again — a status they haven't held since Series 4!
- Chibnall's claim that there won't be old monsters in series 11 suggests that the Daleks will likely be limited to the contractually obligated cameo at most, if they're still bound to that.
- Alternately, the Daleks could be the Greater-Scope Villain behind the original Big Bad, not being revealed until the last few seconds.
- The Cybermen. The main drawback to this would be that they were not only antagonists in the Series 10 finale, but also that storyline was by far the best-regarded Cybermen storyline of the revival to date, making it a Tough Act to Follow.
- The Autons and the Nestene Consciousness.
- The Weeping Angels, who've had no more than passing cameos in the televised franchise since Series 7.
- A mythological creature.
- A renegade Time Lord like the Rani, the Monk, or maybe even the Master/Missy (the last is probably least likely because they were the Twelfth Doctor's Arc Villain).
- A previously one-off villain, like the Sycorax or the Celestial Toymaker.
- An Eldritch Abomination-type villain.
- The Valeyard.
- The Sontarans, considering the fact we haven't had a proper episode with them as villains since Series 4.
- The Terrible Zodin
- The Daleks, Cybermen, Autons, Nestenes, Weeping Angels, Sycorax, Celestial Toymaker, Valeyard, and Sontarans are all Jossed. Chris Chibnall says there will be no old monsters in Season 11.
- Don't discount the potential obligatory Dalek cameo.
- Again, Chibnall’s claim that there won’t be any returning villains or characters in Season 11 makes this unlikely outside of the obligatory Daleks appearance. Furthermore, a new villain race called The Stenza is being pushed as the current series’ alien villain.
- Daleks are the villain of "Resolution", but do not appear in the main series.
- Don't discount the potential obligatory Dalek cameo.
- "The Tsuranga Conundrum" has Freeze-Frame Bonus appearances of a Cyberman, a Sontaran, a Silurian, a Weeping Angel, a Silent, an Ood, a Slitheen, and a Zygon on a computer screen.
- One of the female writers will be Jenny Colgan.
- Jossed: She's not writing for this season.
- Apparently he's writing five episodes. The five guest writers who will write the others are two women and three men.
- The new writers are: Malorie Blackman, Ed Hime, Vinay Patel, Pete McTighe and Joy Wilkinson.
- Because the idea of a pregnant female Time Lord regenerating into a male, is just too icky.
- You mean as opposed to a pregnant female just plain dying and losing the baby that way instead...?
- Plus, for all we know, there could be some sort of Limitation where pregnant Time Lords are forced to remain female until the baby is born.
- Possibly Jossed, at least for series 11. In an interview, the interviewer straight-up asked if looms will be made canon in the show. Chibnall was very surprised by the question, possibly indicating he hadn't even thought about it. His response: "The short answer is, not this series."
- And now definitely jossed for this season.
- Or maybe she'll play up the "Lady" part of being a Time Lady a lot more in such situations, neatly sidestepping old-school sexism by trumping it with equally old-style classism. It's worked for dozens of aristocratic female villains on this show, after all...
- Confirmed: She experiences it in "The Witchfinders".
- Jossed. February 2018 casting news suggested that says there will be a story involving the Civil Rights Movement and specifically Rosa Parks (which would be set in the American South of The '50s / The '60s), and the subsequent reveal by Alan Cumming that he'll be appearing as King James I has quashed this WMG for good.
- Jossed — The Gender Bender is pointed out to her, as she's amnesiac at the time. She takes it well.
- Jossed — He's Ryan's step-grandfather and a retired bus driver. Yasmin, in the meantime, was an old school chum of Ryan's.
- Jossed, and "Resolution" has a mention of UNIT being shut down.
Being limited to contemporary Earth would be an easy justification for no less than three new regular associates/companions for the Doctor, plus a recurring character, being introduced at once; easier on the show's budget at a time when it isn't the money-spinner for the BBC that it used to be (which was one reason it was done back in the day); an easy way to avoid No Equal-Opportunity Time Travel (see above); a major shake-up to the franchise dramatically, and an easy hook for a season-long Story Arc. It would also be a great excuse to bring back UNIT, as suggested above — they were introduced along with the Third Doctor, after all — and have some bridge between this era and previous ones.
On the other hand, there are a lot of potential downsides to this concept. First, there would be Unfortunate Implications in having the first female Doctor also be the first in decades (and more specifically the revival era) to have to forgo adventures in all of time and space, raising complaints of being too tied-down to Earth and especially London that have dogged the revival almost since the beginning (but especially in Series 2 and 8 — coincidentally also Doctor debut seasons). With as many as ten stories to tell episode-by-episode, rather than the four serialized stories of Season 7, how many different, sudden alien invasions and hidden mysterious threats can present-day Earth — and more specifically London — take in a single season? And the Third Doctor at least had his TARDIS around in his early seasons. Would the show forgo its most iconic icon at a time when no characters from previous seasons look to be appearing (and if they do, probably will be kept secret until airing)?
- Looking unlikely, first with the February 2018 news that there will likely be a story involving Rosa Parks and the Civil Rights Movement, and second with Alan Cumming revealing he'll be playing King James I in a 17th century-set episode. So the Doctor might go TARDIS-less for the first few episodes but no more, or — as discussed below — she'll access an alternative means of time-and-space travel and the Story Arc will be her quest to find the TARDIS.
- The first trailer explicitly shows at least two alien planets, one with a green sky and another with three suns, and a few shots that appear to be set in the '50s, making the "stuck on present-day Earth" part of this theory jossed.
- Jossed in the sense of not being stuck in the present day, but as of the Cliffhanger of "The Woman Who Fell to Earth" the TARDIS is still missing in action and the Doctor is trying to track it down.
- Completely Jossed. The TARDIS is located at the end of episode 2, which is set on an alien world.
- Being within the post-regeneration period of time where any and all wounds quickly heal, ala how Ten got his "fighting hand" in "The Christmas Invasion".
- Confirmed. She lands in a stopped train and recovers from that immediately, though she does take a nap later.
- The TARDIS, having dematerialized and had its "sulk" elsewhere/when to repair the damage the regeneration caused while keeping the Doctor herself safe, materializing right behind her to catch her — revealing the new console room in the process.
- The TARDIS tossing her something to help her out — a parachute, grappling hook, jetpack, etc.
- The Doctor flying back into the TARDIS with the help of her key, as with Twelve's stunt in "Death in Heaven". Note: This and the previous possibility assume that the TARDIS did not actually dematerialize at the end of "Twice Upon a Time", which would contradict on-screen evidence.
- An old or new alien race flying in to help out. Mega-bonus points if it's a Time Lord/Lady because aside from the Master/Missy (who is probably not coming back for Series 11 either as Missy or her next incarnation) there haven't been any other Time Lords established as zipping across time and space since the revival began, with the implication that they're all hiding out on Gallifrey near the end of time. This would be an interesting time to introduce an old or new Time Lord character. (Clara Oswald and Me are also an option because they have a TARDIS and Thirteen will now recognize both of them, but it's really unlikely Chibnall will bring them back.)
- Landing on or in a passing airplane, hot air balloon, etc. Bonus points if the new companions are inside!
- Lands in a pool or in a river. Sure, the impact will be bad, but again they'll probably utilize the "post-regeneration fifteen hours" thing that helped Ten regrow his hand, and helped River survive getting shot at by Nazis.
- Use the sonic screwdriver, destroying it in the process. This will be why she needs the yellow one.
- Jossed — She simply lost the old sonic and everything else in her pockets in the fall.
The Doctor stated that only children can hear and understand his name. River Song knew his name, and said that she'd "made him tell" her what it was. That means the Doctor had to have told River his name when she was a child. This could be the first River, who escaped from the orphanage. It could be the River who she regenerated into at the end of "Day of the Moon". Or, it could be the Mel regeneration who grew up with her parents. It's possible that the last two are one and the same, except that it would be difficult for a child to arrange to get herself to a small town in England, plus the timing is off — the first regeneration was in 1969, and Amy and Rory would have grown up in the 90s. (First Amy episode was in 2010.) So either there was another regeneration between the first and Mels....or Mels got a lift from America 1969 to Leadworth in the early 90s.
But why wouldn't River remember meeting a female Doctor, and thus know that more regenerations were possible? Either she never learned who the Doctor was, and was transported unconscious....or the time lines were out of synch, because there was another, older regeneration also present. Thus, we get an appearance by the River Song regeneration and her younger self. We've done multi-Doctor and multi-Master, why not multi-River? She could be a download from the Library, or be from during the 24-years-night on Darillium.
Now, if only we can get Moffat to write one episode (or two-parter) for the Chibnall era....
- Except River doesn't have to understand the Doctor's name to know it. She could repeat the sound of it without comprehending the same meaning to it that a child would.
- This would finally provide an explanation for Ten's statement in "Forest of the Dead" that, "There's only one reason I would ever tell anyone my name. There's only one time I could!"
- Highly unlikely, due to Chibnall's claim that Series 11 will not feature any previously appearing characters.
- Jossed.
- The Sontarans would actually be a great villain to do this with, since they're a One-Gender Race with members who have been shown to have sexist viewpoints ... thus making them considerably more likely to mistake one of the male companions for the Doctor.
- Jossed, unfortunately.
- Also, who says the Sontarans would even realize that Jodie Whittaker's Doctor was a woman? Mistaking people's genders is one of the better Running Gags for their species in New Who.
- That gag is specific to Strax, who notably didn't have this problem before his death and resurrection and is a known cloudcuckoolander. So, should Thirteen ever meet the Sontarans, I wouldn't automatically assume they won't be able to tell she's female.
- Partially confirmed. In "The Witchfinders", the Doctor initially poses as the Witchfinder General, but when the King arrives he assumes the Doctor is the assistant and Graham is the general. However, there's no major production of things.
- Oi! Married!
- Again, Chibnall claims there won't be any previously appearing characters.
- Jossed.
- Oh, maybe she'll call herself Sarah Jane Smith!
- Jossed, the Doctor does not use a "Smith" alias this season.
- Jossed, no pears this season.
- Again, Chibnall claims there won't be any previously appearing characters. In addition, given that the Master was a recurring character during Twelve's run, it's likely the showrunners are going to give them a break for now.
- The circumstances surrounding the new companions appear to have Jossed this one. Yaz and Ryan knew each other in school days, and Graham is Ryan's step-grandfather.
- Totally jossed at the end of the season.
- Chibnall has said he wants Series 11 to be a Jumping-On Point with a focus on newly-introduced elements. While this doesn't preclude an appearance by the Minister of War, it seems likely given these statements that they won't focus on a mention from a three-year-old episode, especially as there are no two-parters this year.
- Maybe the Minister of War is connected to the Stenza.
- Jossed.
- Or she could use a vortex manipulator, ala Captain Jack Harkness and Missy — giving a great excuse to work one or even both (!) of them into a story.
- Or another Time Lord could pitch in to help.
- The first trailer has the TARDIS noticeably absent …
- The TARDIS is also missing in the second trailer. In fact, all of the promotional material involving the Thirteenth Doctor and this season, starting with her reveal video, long before the cliffhanger of "Twice Upon a Time" was known, has the TARDIS either absent or in the background, at a distance.
- Confirmed. She rigs up the new sonic on her own. At the end of "The Woman Who Fell to Earth" she also rigs up a device to follow the TARDIS energy signal and teleports herself — and, by accident, Yazmin, Ryan, and Graham — to somewhere in the depths of space for the Cliffhanger. Will they find it in "The Ghost Monument"?
- Partially confirmed: it's a part of the plot for the first two episodes, but is located at the end of "The Ghost Monument". The actual arc looks to be shaping up as something else.
- Confirmed. She rigs up the new sonic on her own. At the end of "The Woman Who Fell to Earth" she also rigs up a device to follow the TARDIS energy signal and teleports herself — and, by accident, Yazmin, Ryan, and Graham — to somewhere in the depths of space for the Cliffhanger. Will they find it in "The Ghost Monument"?
- Jossed. She simply lost it — and everything else that was in her pockets — in her fall from the TARDIS.
- The Doctor will be mistaken for a witch. That James had a phobia of witches is historical fact (hence why the line "suffer not a witch to live" is in the King James Bible), so it's perfectly plausible that he might assume the Doctor to be one, especially since it would be fairly easy for her to come off as one either accidentally or intentionally. Or the Doctor's use of high-tech "magic" to foil a nasty scheme in which James is involved will cause his subsequent enmity for witches.
- Confirmed; King James assumes that the Doctor is a witch responsible for the Monsters of the Week and sentences her to the ducking stool.
- The Doctor will mention knowing Queen Elizabeth I. Since she was James' predecessor on the English throne, and since the Doctor does occasionally bring up historical figures s/he's met before, this would be perfect. Perhaps the Doctor will mention being married to Elizabeth I. As a result, the companions will erroneously assume that she was a lesbian. The Mistaken for Gay part is looking unlikely however, since the Doctor has freely mentioned her Gender Bender to her companions, so they are perfectly aware she used to be a man.
- Jossed; the Doctor never mentions her relationship with Elizabeth.
- The Solitract takes the appearance of a frog in "It Takes You Away", but it may not be related.
- And... jossed for this season.
- There's something wrong with time on Earth (again) and these rifts are being caused by whatever's behind it.
- The Doctor's built another time-travel device to use while she looks for the TARDIS (see above guesses), which is both causing the time-stop effect and is how she can just appear and disappear like that.
- This is jossed as the TARDIS is recovered at the end of the second episode.
- Chibnall claims that Series 11 will be focusing on all-new elements, explicitly including locations. With that in mind, a return to Gallifrey seems unlikely this year.
- Jossed.
- Someone/something sabotaging it from within or without when the Twelfth Doctor wasn't around, or even when he was — possibly even attacking while he was regenerating and the TARDIS was in the time vortex:
- Missy, during/post-"Empress of Mars"
- The next incarnation of the Master, if Missy's Heel–Face Turn didn't hold out
- The Time Lords
- The Black Guardian
- The Daleks
- The Valeyard
- A new antagonist, perhaps the season's Big Bad
- A neutral or good force that accidentally or mistakenly saw the Doctor as a foe
- A symptom of a larger problem in the space-time continuum, ala the cracks in Series 5, and which may or may not be an Evil Plan at work; could in fact be the time rifts that appeared in the Series 11 teaser (see above).
- A sign that the TARDIS itself is wearing a bit thin after so many millennia with the Doctor.
- Jossed, it seems it was instead an Exact Words as a Dalek appeared right after the year and season ended. Nothing else appeared in the main series.
- Unlikely, since Chibnall and Strevens indirectly confirmed that there was a Christmas special at SDCC 2018 by joking about how they seemed to be filming an extra eleventh episode when asked about a Christmas special.
- Jossed, and it's not a Christmas special anyways.
- Unlikely, see above.
- Confirmed, and for the exact same reason! Chibnall ran out of ideas for a Christmas special, and we will get a New Year's special instead.
- Right, scratch that, the BBC just said it is premiering in October. So, new likely premiere date: October 6.
- Specifically, they said it was premiering by October. So, again, I'm guessing October 6 as the latest possible likely premiere date.
- Apparently, the show is now switching to Sundays, and will premiere on October 7th.
- Specifically, they said it was premiering by October. So, again, I'm guessing October 6 as the latest possible likely premiere date.
- Jossed.
- Confirmed... Rest in peace, Grace O'Brien.
- It's not actually a Christmas special at all.
- Jossed.
- Looking unlikely as of "The Woman Who Fell to Earth". They're all pretty credulous about aliens once they encounter them but there are no hints any have had previous experiences with such.
- Jossed.
- Jossed, although James does ham it up.
- In addition, they will be at or near the locations they're seen at in the World Cup teaser when they hear or see the Doctor landing.
- Confirmed — Graham and Grace were on a stopped train and Ryan and Yaz were just arriving to help them when the Doctor landed in it. Moreover, Graham is Ryan's step-grandfather and Yaz an old school chum of Ryan's, so there's reason for them to stick together.
- Jossed: The spaceship belongs to one of the guest characters of "The Ghost Monument", and the TARDIS is recovered by the end of that episode.
- Unlikely. Chibnall said series 11 would tell "one big story".
- Jossed with the TARDIS still missing in action at the end of "The Woman Who Fell to Earth" and the Doctor (and, inadvertently, her not-yet-companions) heading out to find it via a new device. With episode two ("The Ghost Monument") the first off-world adventure and episode three confirmed as the Civil Rights Movement episode and thus the first quasi-historical story, that's two episodes that don't have to end with getting the TARDIS back and returning the companions to modern Sheffield.
- Further Jossed by "The Ghost Monument". Although the TARDIS is found by the end of the episode, it's revealed that the Stenza, the species of the antagonist of "The Woman Who Fell to Earth", are responsible for the episode's setting being turned into a Death World, and there's an implication we haven't seen the last of them. Also, there's mention of a "Timeless Child" which seems significant.
- At the same time, confirmed. Apart from the villain of "The Woman Who Fell to Earth" returning in "The Battle of Ranskoor Av Kolos", there is no real arc this season.
Post-release theories (unmarked spoilers)
- Jossed.
- It's been discussed numerous times in the show that contemporary humanity has a tendency to ignore, handwave or just forget about even the most blatant signs of alien life over time - additionally, only Graham directly denies that aliens exist. Ryan suggests aliens early on, and Karl only denies that aliens would show up in Sheffield, so it could just be chalked up to Graham being old and a bit of a curmudgeon.
- Some further evidence towards this theory can be found in "The Ghost Monument", where it's revealed the Stenza have a large, long-standing empire which has conquered parts of the Twelve Galaxies, yet the Doctor hadn't heard of them before. Maybe such an Empire didn't exist in the Doctor's native universe, which would explain her ignorance? Also, the TARDIS being locked in dematerialisation loop could be explained by her trying to adjust to the alternate universe. As we saw in "Rise of the Cybermen", normally the TARDIS wouldn't be able to use the energies of an alternate universe at all, but maybe the fact that she was partially destroyed while being transported there allowed her to regenerate in a form that could draw power from the parallel universe?
- On the other hand, the universe is a very big place, and Tzim-Sha is said to have been transported to Earth from 5,000 galaxies away. So they are a threat, but it's more plausible that the Doctor's never heard of them.
- Except that the Doctor knows the Twelve Galaxies, since she offered to take Ace on a trip around them in "Dragonfire", so it's a bit odd she wouldn't know about the Stenza having conquered them.
- It could be a different Twelve Galaxies. There are billions of galaxies, after all.
- Alternatively, her being more able to healthily process her grief and trauma compared to her predecessors will be why the Valeyard becomes a separate entity - utilising a moment where she's at her lowest point to free themselves, a manifestation of the darkness the Doctor is now on the path away from.
- The Alternate Universe counterpart theory may have some evidence to back it up. For a while before the premiere, Sharon D. Clarke's character was thought to be named Mary, and Clarke herself even referred to the character as such during a radio interview. This might have been obfuscation to avoid revealing the character's real name, but it could also mean that the TARDIS team will visit another reality where another version of Grace is alive, but named Mary instead.
- Or she could be playing her own relative, perhaps in the Rosa Parks story if some of her family were American.
- Confirmed. Grace appears as a figment of Graham's imagination in Episode 4. In episode 9, she is impersonated by the Solitract.
- As much as it'd be neat for this to be true... probably not. The Doctor breathing out the extra regeneration energy is the exact same effect that happened with the Tenth and Eleventh Doctor, making it more likely just a Continuity Nod.
- Actually kind of confirmed, but not in the way the theory guessed: the teleporter, apart from bringing along Graham, Ryan and Yaz, sent everyone to the right place. However, Desolation, the planet the TARDIS could be found on, had recently been knocked out of its old orbit, which is why they were left drifting in deep space. The TARDIS became known as the "Ghost Monument" when the planet was inhabited because it was stuck in a materialization loop where it would appear, half-materialized, once every thousand years.
- Confirmed, in the sense that there are more references to the Stenza in this episode: they're responsible for both the genocide against Angstrom's people and the ruin of Desolation's ecosystem and elimination of its populace, the latter via forced WMD development and testing. The theory that they would become the Big Bad of the series is Jossed, however. Tzim-Sha does appear again in the series finale, but we've yet to see any other Stenza, or their empire.
- Also Confirmed: it's been phasing in and out of Time due to its damaged condition.
- If it's a previously-established character, it's...
- "[A]n early, forgotten regeneration of the Doctor" as suggested at the AV Club review of the episode, ala the War Doctor coming between Eight and Nine. Could they be who Missy was talking about when she told Clara she knew the Doctor since they were a little girl in "The Magician's Apprentice"? The lie was apparently the stuff about the moon and the President's wife, after all, to go by the Doctor's claims in "Hell Bent".
- That would go against the established fact that Time Lords can only regenerate 12 times, since all of the Doctor's incarnations before he was given a new set of regenerations are accounted for. As of "The Day of the Doctor", the only time we haven't seen him regenerate from one body to another onscreen is when the War Doctor started to regenerate, as we didn't see him turn into Nine. So technically there would be a space there to add a new incarnation between him and Nine, but then they would have to break the rule of 12 (as well as explain why the Doctor doesn't remember this incarnation, of course).
- Except that when War regenerated, we could clearly see him start to become Nine before the scene changed.
- Maybe that's what Timeless Child means. Maybe the Doctor was born as a girl lacking any Time Lord essence — hence "timeless" — so no time-awareness, no extended lifespan, and no regeneration. Eventually they managed to turn that child into a proper Time Lord through a regeneration-like process, and that boy became the proper First Doctor, with a regeneration count at 0.
- Confirmed, The Timeless Child is in fact the collective name for the pre-Hartnell incarnations of the Doctor. The Doctor is in fact not subject to the 12-regeneration limit, as she is not really a Time Lord but something much older and stranger.
- Alternativly it's not a prior itteration but literally the Doctor as a child.
- Susan Foreman. On the other hand, the Doctor definitely remembers her.
- An incarnation of the Master, and not necessarily a post-Missy one.
- Adric, one of the very few children who ever traveled with the Doctor long-term. Maybe he didn't die and resented that the Doctor never came back for him, and he found some other way to get around space and time?
- Grace O'Brien. Surprise!
- The Valeyard
- Davros
- "[A]n early, forgotten regeneration of the Doctor" as suggested at the AV Club review of the episode, ala the War Doctor coming between Eight and Nine. Could they be who Missy was talking about when she told Clara she knew the Doctor since they were a little girl in "The Magician's Apprentice"? The lie was apparently the stuff about the moon and the President's wife, after all, to go by the Doctor's claims in "Hell Bent".
- If it's an all-new character...
- The REAL Hybrid. Sure, Steven Moffat said it really was the Doctor and Clara together, but...
- A previously-unmentioned family member of the Doctor. If it's one of their own children, the mother could be the Doctor's original wife (Susan had to come from somewhere), River Song (during the 24 years on Darillium), or someone new to the mythos.
- The Doctor BEFORE they were the Doctor, ala The Other in the Virgin New Adventures novels.
- The Doctor before becoming the Doctor, aka the little boy Clara found crying in the barn.
- The Doctor's child/Susan Foreman's parent. Susan is the Doctor's granddaughter, so by definition the Doctor must have a son or daughter that'd go on to father/mother Susan. Ever since the Second Doctor, their family has been treated as MIA/disconnected/dead, so they showing up would be quite the Wham Episode. And given how long the Doctor has been separated from them, of course they'd be terrified and hide that deep inside of themselves. Plus everyone who knows about Susan Foreman has been wondering what the hell happened to her, and especially the link between the two generations.
- The Minister of War
- The synopsis for "Rosa" says that the main characters "discover a plot to change the course of history". It's possible that the antagonists could be human time travellers who are trying to Make Wrong What Once Went Right.
- Jossed: The antagonist of the episode is a time-traveling racist who's trying to throw off the course of history by disrupting Rosa's famous bus ride.
- The last time the Doctor dealt with giant spiders was in the third incarnation's memorable Grand Finale, "Planet of the Spiders", where the titular arachnids were a psychic alien species attempting to invade the Earth and regain the crystal that the Doctor had stolen from them. Could this episode then in fact be their long-awaited return to the series?
- Jossed, they’re actually domestic spiders made bigger by people Playing with Syringes.
- Confirmed he will return at least; apparently he's showing up in the new year's special, "Revolution of the Daleks". Whether he gets comeuppance is yet to be seen.
- They will also work with the Stenza.
- Very likely jossed, as Thirteen faced off against a very different incarnation of the Master in the next season.
- It's a Contrived Coincidence: they only sent out one request for help, and it just happened to go to the Doctor, someone who can help them.
- The sender put the message in as many different deliveries as possible, to ensure a wide distribution in the hopes that one of those people would respond, and the Doctor is therefore one of many recipients.
- The Doctor was deliberately targeted by the message, as the sender has heard of her in some way before, and figures she might help.
- Confirmed: the message was sent by the Kerblam! system AI, which is strongly indicated to have heard of the Doctor's reputation.
- Bizarre Alien Reproduction.
- The grandmothers were from multiple generations, including great-grandmothers, great-great-grandmothers, etc., and it was normal for all ancestors in those positions to simply be called grandparents for simplicity purposes, since Time Lords are so long-lived.
- Multiple regenerations of a smaller number of individuals.
- "Granny", in Gallifreyan society, is a catch-all term for "elderly female loved one known in childhood", regardless of whether or not they're biologically related.
- Considering that Series 12 is teasing some more exploration of Gallifrey, Omega could appear as a new villain. Since he's associated with Antimatter, maybe it will turn out he was behind the events of It Takes You Away.
