"There's always a twist in the end!" Russell T Davies warned us at the end of "The ポルノ映画 水を飲ませるDevil's Chord," with a musical number that proved prophetic. While Whovians might have thought at first that Doctor Who's Season 14 showrunner was talking plot twists, we're now realizing he meant Susan Twist is always in the end credits.
Who is she, and why are Whovians losing their collective cool over Susan Twist? Well, it's because the elderly English actress is popping up again and again on Doctor Who, and in a very timey-wimey way.
Sure, all kinds of actors have appeared on the iconic series over its decades of television. Sometimes they pop by over and over, prompting Davies to create an in-show explanation for these anomalies. For example, hot Scottish actor Peter Capaldi got upgraded from Pompeii resident to Twelfth Doctor. But there's something especially curious about Twist's appearances, as they've all come in a recent jumble.

This collision of cameos has got fans theorizing all kinds of possibilities for what Davies has up his sleeve. With the latest episode, "Rogue," there are fresh clues to who Twist is really playing. So, let's pick through the appearances and the fan theories one by one.
Susan Twist in "Wild Blue Yonder"

In this adventure, the two are flung far into the future, where they are plagued by creepy doppelgängers of themselves. But Twist pops up before these freaky sci-fi events. FAR before. We're talking the opening sequence set in 1666 England.
There, a dashing Isaac Newton (Nathaniel Curtis) is on the brink of "discovering" gravity. On his walk to that fateful apple tree, he comes across Mrs. Merridew (Twist), a smiling, bonneted servant who tells him, "Don't come back until you find a really good idea, sir!"
And that's it — so brief a moment, longtime Whovians took no notice of it on its own.
Susan Twist in "The Church on Ruby Road"

The first full episode featuring Ncuti Gatwa as the Fifteenth Doctor also introduces his new companion, Ruby Sunday (Millie Gibson). A foundling who lives in London, when Ruby's not searching for her birth parents or rescuing newborns from sky-sailing gremlins, she's in a band!
SEE ALSO: 'Doctor Who' Christmas specials ranked, and where to watch themOn December 22, 2023, Ruby is playing keyboard at a Christmas concert at a bar. The Doctor is watching this performance, but he's not the only one. A long-haired woman yells out to the lead singer, "Give it some welly!" Then she requests a song, saying, "Can you do 'Gaudette'?"
If you don't recognize that title, it may be because this rowdy concert attendee (also played by Twist) is referencing a Christmas carol that dates back to the 16th century. So despite her vaguely flower-child vibe, with her paisley jacket, long locks, and headband, her references go way, way back.
Susan Twist in "Space Babies"

In one video, Twist pops up in a teal and gray crew uniform (giving Star Trek vibes), and introduces herself as Comms Officer Gina Scalzi before signing off in the year 21506. So from her first appearance to this one, Twist's face is popping up across 19,840 years.
Susan Twist in "The Devil's Chord"

The Doctor and Ruby were hoping to take in the groovy mood of 1963 London — and more specifically, the recording of the Beatles' first album at what would someday be known as Abbey Road Studios. But the beat is off. Music is bad, and people feel bad. And while Ruby and the Doctor are looking to give John Lennon and Paul McCartney a pep talk, a chatty cafeteria worker butts in with a bizarre interjection.

The pair are mock-outraged by the price, and she responds, "Take it or leave it, sweetheart." The Doctor chides, "That is daylight robbery," and she replies, "That's me: Margaret Lockwood in The Wicked Lady. Now there was a woman. Statuesque!"
The Wicked Lady is a film from 1945, in which Margaret Lockwood plays Barbara Skelton, a noblewoman who steals a friend's affluent betrothed and then hits it off with a rakish highwayman. So, that robbery connection explains why the character is referencing this movie. But what is Davies doing with this dialogue?
Susan Twist in "Boom"

But these mysterious foes aren't the only trouble. An overenthusiastic AI ambulance can also be a major threat, as a recently blinded John Francis Vater (Joe Anderson) discovers when the ambulance non-consensually euthanizes him into a pocket-sized "casket" made of smelted marine.

Susan Twist in "73 Yards"

Set in modern-day Wales, "73 Yards" begins with Ruby losing the Doctor over a fairy ring. Then, she realizes she's being stalked by an old woman — who stays consistently 73 yards away. As fans have already been giddy to identify Susan Twist in each episode, you might well have expected her to be the mystery lady on the far-off hill. But instead, she played a happy hiker Ruby met as she made her way to a local village.
Dressed warmly for the chilly cliffside weather, Twist sports an aqua-colored winter coat, white gloves, and a matching knit hat as well as a pair of walking sticks. By contrast, Ruby in her mini-skirt and fall jacket is clearly underdressed for the temperature, which is why this hiker says, "You must be mad! Is that all you're wearing?!"
From there, the unnamed hiker tells Ruby that the town she can spy in the distance is Glyngatwg. But then this lady with the English accent adds, "If you'll forgive my pronunciation — which they don't." This suggests that like Ruby, she's an outsider to the area. But before she can say much more, Ruby interrupts.
"I haven't met you before, have I?" Ruby asks. While fans might be gasping at home, Twist's hiker says simply, "I don't think so. Have you?" Ruby dismisses the idea, then asks the hiker to talk to the stalking woman for her. She has some initial reluctance. ("Have I walked into something?") But she kindly obliges after urging Ruby, "Get into the warm, both of you — whatever little game this is." Then the hiker approaches the woman and talks to her. They are too far away for us — who are locked at Ruby's side — to hear what they say. But we can hear the hiker screaming as she runs away from the woman andRuby.
Notably, in their exchange, Ruby mentions "the Doctor," to which the hiker asks, "Do you need a doctor?" That might suggest she has no idea who the Doctor is — which would dispel some fan theories. Or maybe she doesn't know yet? Time is a funny thing on Doctor Who.
Susan Twist in "Dot and Bubble"

Credit: Disney+ screenshot Playing like Doctor Who's answer to Black Mirror,"Dot and Bubble" centers on Lindy Pepper-Bean (Callie Cooke), an affluent and carefree resident of Finetime, a human colony that's essentially a playpen for the vapid offspring of the the obscenely wealthy. Speaking of this upper-crusty group, that's where Twist appears this time.
While the Doctor and Ruby are trying to navigate Lindy away from the ravenous jaws of a peculiar space beast, Twist pops up in a brief but compelling video panel as Lindy's mother, Penny Pepper-Bean. She first appears when Ruby asks how Finetime works, and Lindy explains that "just people 17 to 27" come here from the Homeworld, their way funded by their posh parents. "Mummy paid for it all," Lindy says, prompting the display of a saved video from her mother to appear.
"We miss you so much, darling!" 62-year-old Penny Pepper-Bean says, "But I'd pay for the whole moonto make you happy. Just look up to the sky and wave to us on the Homeworld! Happy Finetime, Lindy Lu! And remember, you're only a bubble away."
The message itself seems standard doting parent stuff, but the Doctor and Ruby are thrown because they finally recognize Twist's face. "I've seen her before," Ruby says, to which the Doctor replies, "Yeah, she's the face of the Ambulance from Kastarian 3." (That's the planet in "Boom.") But Ruby argues, "No, no, no. I've seen her somewhere else."
Ruby is most likely remembering Twist's face from "73 Yards," where she had the most face-to-face time with her amid her Welsh misadventure. But before they can dive into this conundrum, it's back to the task at hand — saving Lindy and the other "rich kids" from this futuristic Love Island.
Susan Twist in "Rogue"
Set in Regency-era Bath, "Rogue" thrust the characters of Doctor Who into a Bridgerton scenario of romance, shape-shifting, and murder. But Twist doesn't appear in the actors' end credits here, because she's only shown as a portrait. In the duchess' grand estate, Ruby notices an oil panting of a regal-looking gray-haired woman on the wall, and asks her hostess who it depicts. "The duke's late mother," the duchess (Indira Varma) replies, noting, "Her eyes still follow me about the room. Constant judgment."
And that's it. Curiously, like her first appearance, this means Susan Twist is playing characters who exist within the Doctor's adventures, even if they never interact with him or his companions.
What does all this mean? Here are some fan theories.
Fan theory: Susan Twist is The One Who Waits.
In "The Devil's Chord," Maestro mentions being a part of a "Pantheon" of god-like beings, which we already know includes their father The Toymaker ("The Giggle," Special 3). But before the musical villain is gobbled up by an iconic piano, they cry out a warning: "The One Who Waits is almost here!"
This suggests The One Who Waits is a part of this Pantheon, and maybe even its most powerful member. So, The One Who Waits may well be the Big Bad of Season 14.
Perhaps this is why Twist is popping up again and again, with more screen time and more important parts to play in the Doctor's adventures. If she is The One Who Waits, is this how the powerful being is crawling closer and closer to the Doctor? Unbound by time and space as both the TARDIS and the Doctor are, this would make The One Who Waits a fearsome foe to be sure.

Fan theory: Susan Twist is Ruby's birth mother.

"The Church on Ruby Road" showed that coincidence and bad luck follow her. "The Devil's Chord" revealed there's a song in her heart, but also something that scared Maestro enough to proclaim, "This creature is wrong!"
Even the Doctor has slyly given Ruby a TARDIS scan, though he hasn't shared with the audience what he found.
There are other strange elements about her origin. The Doctor's memory of it changes, with her cloaked mother turning toward him in an apparent warning. And then there's the recurring snowfall, which follows Ruby into the TARDIS and onto the warring planet with no clear explanation. Could it be that Susan Twist is somehow a part of the Ruby Sunday mystery? What a twist that would be!
Fan theory: Susan Twist is Ruby Sunday.
Millie Gibson is Ruby Sunday. Credit: Lara Cornell / Bad Wolf / BBC Studios In "The Devil's Chord," the Doctor mentioned that in 1963, he was living in London with his granddaughter Susan on Totter's Lane. This aside slyly reveals to Whovians new and established that a character can cross their own timeline. And perhaps whatever Ruby really is allows her to do this, resulting in two actresses secretly playing the special companion.
Alternatively, Davies might be pulling a Moffat move from Season 6, episode 10, "The Girl Who Waited." In that misadventure, an alternate version of Amy Pond is trapped in a resort planet for 36 years alone. Could it be that Susan Twist is playing an alternate reality version of Ruby Sunday? And could the title "The Girl Who Waited" be a clue that this alternate version might also be The One Who Waits? Possibly! Though now that we've seen the twist of the "73 Yards" mystery woman, this theory seems less likely.
Fan theory: Susan Twist is... Susan Foreman?
Back again to "The Devil's Chord," where the Doctor name-drops his granddaughter Susan but says he has no idea if she survived the Time Lord genocide. Ruby seems astonished he hasn't looked into this. But is it possible his granddaughter is looking for him?
Susan Foreman was the first companion of the First Doctor when the show began in the 1960s, but she hasn't been a major part of the lore of the relaunched TV series until Davies brought her up in Season 14. Her role was originated by Carole Ann Ford, who has reprised the part in podcast adventures, most recently 2023's Doctor Who: Once and Future. So, you might well wonder, why would Davies recast her? Maybe bringing back Ford would give the game away too soon.
With decades of lore to play with and all of time and space as his playground, Davies has fans in a tizzy over what the meaning of Susan Twist's curious recurring roles will be. So, if "There's Always a Twist in the End" is a meta clue to indicate we should look for Susan Twist, could her first name be a clue, too?
Perhaps this Susan Twist could be the new Susan Foreman, searching the whole of the universe and existence for her long-lost grandfather, the Doctor.
Fan theory: Spatial Genetic Multiplicity
In an interview with Mashable ahead of the Season 14 premiere, Davies employed this term to explain how actors could appear in Doctor Who even though they star in shows that exist within the world of the Whoniverse. For example, Bridgerton, which gets a shout-out in "Rogue," has several cast members who've mixed it up with the titular two-hearted hero.
Davies coined the term "spatial genetic multiplicity" to create a sci-fi justification for why the same face might appear in different roles across the reality of the series. But could he be pushing this concept to strange new territory with Twist?
This wave of a timey-wimey word is enough for most Whovians to shrug off these meta collisions. But when Doctor Who cast Capaldi as its Twelfth Doctor, spatial genetic multiplicity wasn't blamed. Instead, Capaldi's familiar face — first seen in the pivotal episode "The Fires of Pompeii" — serves as a reminder of a moment the Doctor took mercy, saving lives instead of upholding the supposed tenets of Time Lord time travel.
Could it be that Twist's face is meant to have a similar resonance for the Doctor? Is it that her face is following the Doctor — even appearing before Gatwa made his appearance on the series as the Fifteenth Doctor — to signify some bigger message?
Only time (and more episodes of Doctor Who) will tell.
