Thin Ice was the third episode of series 10 of Doctor Who. It was written by Sarah Dollard, directed by Bill Anderson and featured Peter Capaldi as the Twelfth Doctor and Pearl Mackie as Bill Potts.
The events of this story follow on directly from Smile, with the TARDIS arriving in London just moments after the Doctor and Bill left the human colony planet.
Bill repeats many of the concerns that Martha Jones expressed in TV: The Shakespeare Code word for word, such as the fact that she has arrived in a time period when black people were still enslaved and treated poorly. Unlike Martha in that episode, Bill experiences racism from Lord Sutcliffe. Bill also initially thinks that time travel worked like the movie The Butterfly Effect, where she could erase herself from existence by the smallest change to history.
The Doctor did not run into his previous incarnation, who had brought their wife River Song to the last Frost Fair to hear Stevie Wonder sing for her birthday, as was revealed in A Good Man Goes to War.
It is also the first episode since 2006's New Earth that a character has almost said a strong swear word, only for the scene to change.
The Doctor's morality and ability to be indifferent towards people dying is also brought up again. As the Doctor goes on to explain, he has to put his outrage aside and keep a cool head to prevent even more losses. He is also shown not to tolerate racism, as he punches out Lord Sutcliffe for insulting Bill.
As was the case in Cold Blood and Kill the Moon, the Doctor shows a refusal to do anything that could drastically alter the history of Earth on his own. Instead, he makes his companion make the decision.
Synopsis
Trying to get back to the university before Nardole notices he broke his oath, the Doctor accidentally lands himself and Bill in the past, at the final frost fair in 1814. He decides to enjoy the unexpected trip.
However, something sinister is lurking below the frozen Thames.
Plot
The Doctor and Bill are shocked to find themselves on the ice of one of the Frost Fairs, seeing an elephant. Before Bill has more time to come to terms with what she's seeing, the Doctor rushes her back into the TARDIS. As the Doctor works at the controls, Bill inquires if they've gone to a parallel world. The Doctor tells her that it's NOT; its Febuary 4th, 1881, the last Frost Fair. Bill questions why they aren't back, asking the Doctor why he can't steer the TARDIS. The Doctor states you don't steer the TARDIS, but negotiate with it (rather unsucessfully). "She's a bad, bad guy this one. Always looking for trouble."
The TARDIS moves to a bridge above the Thames. They exit back out, with the Doctor explaining that the thaw comes tommorow, so he needed a more reliable parking spot. The Doctor is up to going to the fair, but Bill points out that they're in an era where her race was enslaved. He dismisses her worries, telling her where to find the wardrobe. Bill then laughs that the TARDIS has dresses.
Elsewhere, a drunken man follows the lights across the ice to an area of thin ice before being sucked under leaving only his drink bottle behind.

The TARDIS detects trouble
Bill steps outside the TARDIS later, dressed in period clothing. The Doctor exits next, wearing a suit and top hat. Bill wonders if there's anything they need to be on the lookout for, as the Doctor shuts the door. As they leave the TARDIS, they miss an alert message that a large creature is living in the River Thames.
As they walk, Bill asks about being in the past; she wonders if the future could be changed by the slightest things she does. The Doctor jokes their friend stepped on a butterfly and ceased to exist; now Bill can't even remember him. Bill notes the Doctor's joking; they were the only passengers in the TARDIS. As they walk, a street urchin offers them a flyer for the Frost Fair on the Thames, which they attend.
Watching a wrestling match, Bill cheers enthusiastically; the Doctor, however, is not that impressed. He tells her that 'real" wrestling involves zero gravity, tentacles and magic spells. Amused by the idea, Bill notes that Regency London is a lot more racially diverse than she remembers from the movies. The Doctor remarks that "history is a whitewash", even suggesting that Jesus Christ could have another race other than Caucasian. They visit a pie shop, where the Doctor has a bet with the proprietor over a coin toss; Bill enjoys some pie, noticing green lights under the ice. The Doctor tells the pie man that he knows he cheated on the coin toss, asking him how he did it; it's a very impressive trick. However, the man takes offense. The Doctor attempts to diffuse the tension by stating he's a skilled con man too, saying he could steal anything in the shop without him knowing it.
Kitty tries scamming the Doctor
Bill and the Doctor are promptly thrown out by the pie man, with the Doctor revealing he managed to steal some more pie. Right as Bill begins asking the Doctor about the lights, he reveals that he saw them too; he just didn't bring it up, so Bill could enjoy the fair. They are approached a girl named Kitty, who asks for help looking for her lost dog. Bill finds her adorable, willing to help. The Doctor looks at the leash Kitty is holding, asking her to describe the dog; a boy in a large red hat sneaks up on the Doctor. Kitty tells him that she's looking for a small black dog. Smiling, the Doctor congratulates Kitty on her con, knowing she was lying because the leash belongs to a big white dog. He quickly grabs the boy's hand as he attempts to pickpocket his sonic screwdriver from behind, only for the girl to kick his leg, enabling the pair to flee.
Inside their hideout, the boy, Spider, wonders what the sonic screwdriver is. Kitty doesn't know, but guesses it could be worth a lot of money. Having lost sight of them, Bill wonders what they stole; the Doctor tells her that its a sonic (because it makes noise) screwdriver (in a broad sense.) They head to sell it, being spotted by the Doctor and Bill. The kids run past "Thin Ice" warning sign, with Kitty making it back to shore. However, Spider becomes distracted by the green lights, despite Kitty yelling at him for not sticking close to her. Spider is sucked under leaving only his outstretched arm, with the sonic screwdriver, protruding through the ice.
Though the Doctor tries, he cannot save him and only manages to retrieve his screwdriver. His relief at having done so and his seeming lack of care towards the boy's death causes Bill to run off. The Doctor finds her huddled in a secluded spot, telling her that they have to get to work. Bill yells at him to stop telling her what to do; he jokes back that as her tutor, he's supposed to. Angered by his indifference towards the death of that boy, Bill demands to know how many people he's seen die; he's lost count. She then demands to know how many he's killed; the Doctor stays silent. The Doctor tells her that he is 2000 years old and doesn't have the time for the luxury of outrage otherwise more people would die.
Kitty overhears them talking about a monster that could gobble them up. The Doctor tells her that he knows there has to be more kids living rough like her, offering his help. Convinced, Kitty takes the Doctor and Bill to meet the rest of the urchin gang - including the girl who handed Bill the flyer. The Doctor asks them if they've seen anything unusually, producing pies he stolen for them and reads them stories. A little girls mentions a man with a tattoo of a ship on his hand paid them to hand out flyers of the fair. Kitty asks Bill if the Doctor can really help them, to which Bill says he can.
Night at the Thames
The Doctor and Bill walk along the river, wondering about the lights that "eat" people. He decides that the only logical conclusion is to "get eaten". Finding some diving suits, the Doctor and Bill don them as preparation of being pulled under by the lights. Lights begins spinning around Bill below the ice. As her yells cannot be heard by the Doctor due to their primitive diving suits, Bill throws her lantern at the Doctor to gain his attention before she is sucked under the ice. The Doctor jumps through before it reseals, making a human sized hole. Down below, Bill is safe; she and the Doctor discover a giant sea creature chained at the bottom of the river. Bill sees the hat belonging to the boy who was sucked under in its mouth before they come back to the surface.

The Doctor examines the fish
On the surface again, Bill tells the Doctor that the creatures cries sounded of misery. The Doctor notices the pie man harvesting the odd angler fish, yelling to get his attention. The man promptly flees. The Doctor yells for him to wait, as he loves his con. Bill is sickened to learn the pie she ate was made out of those fish; she loved that fish pie. The Doctor picks up a fish, examining it, wondering what they get out of helping feed the creature.
Deciding the pie man might have answers, they quickly catch him. The Doctor earnestly asking for the pie man to teach him the coin trick. However, Bill reminds him that they have more pressing matters. The Doctor asks if the man's seen someone with a tattoo of a ship, but is silent. Wondering if the man's against tattoos, the Doctor states that he is as well; "I think that we are bonding." Bill points out the flaw in the question; asking if he's seen someone with the tattoo of ship near the river. Realizing that this will get them nowhere, the Doctor asks if the pie man has heard of anything odd going on near the Thames. The pie man reveals that the dredgers have been working very hard.
Day time.
The Doctor and Bill observe the dredgers hauling buckets of gunk out of the Thames. Bill wonders how they are going to get past the guards, prompting the Doctor to flash the psychic paper; Bill reads off that it says he works for the palace. The Doctor notes that he hasn't heard that one in a while. They walk down to the operation, who asks them if Lord Sutcliffe knows they are here. Muttering the question to himself and Bill, the Doctor takes out the psychic paper, saying Lord Sutcliffe insisted upon them coming for an inspection. As the foreman walks off to check on the workers, Bill inspects a brick of the gunk, wondering why they're investigating over a mile away from the creature; the Doctor tells her that the creature's head is back by the fair. They're on the other end of it now, meaning that it's not mud that the dredgers are hauling out of the Thames; it's the creature's waste matter. Bill drops the brick in disgust, quickly wiping her hand on her coat.
Rejoining the foreman, the Doctor inquires if it's been ensured that no-one follows the muck being transported to Hampton; however, the foreman corrects him, explaining the carts go to the steel mill. The Doctor quickly covers the blunder explaining "Hampton" is code for the steel mill; "we have to speak in code, or anyone can come down here and get you blabbering away." Noting that the foreman is a man of intelligence, the Doctor goads him into revealing what he knows about the "muck". The foreman tells them that the waste of the creature is more efficient than coal and can even burn underwater making it a highly valuable resource. The Doctor realises that it could be used as space fuel; there's a possibility that an alien might be behind this. When the foreman ask if he'll still have to keep his current job, hoping for a promotion, the Doctor half-jokes that he won't be having a foreman much longer.
Lord Sutcliffe
They visit the manor home of the employer Lord Sutcliffe to determine whether he is an alien. The Doctor insists he does the talking as they must charm Sutcliffe and Bill is likely to become angered due to the creature eating the children. Under the guise of "Doctor Disco of the Fairbrook Society", the Doctor meets Sutcliffe who instantly makes sexist, classist but mainly racist, remarks towards Bill even calling her a "creature" and demanding she shows "respect in the presence of [her] betters". Bill quietly seethes with anger, with a look of disgust on her face. The Doctor taps Sutcliffe on the shoulder, prompting him to turn around for a punch to the face. As Sutcliffe falls down, the Doctor states Sutcliffe is very clearly human. Bill agrees that if Sutcliffe was an alien "then that was pretty convincing racism."
Bill and the Doctor are quickly captured by Sutcliffe's minions with a bruised Sutcliffe revealing the creature has been a family secret for years. The Doctor deduces Sutcliffe funded the current fair, as the regular one wasn't able to draw in enough victims for the creature to digest. Sutcliffe plans on blowing up the ice and sinking numerous victims to feed the creature. Bill is confused, as everyone will see it; however, Sutcliffe states the people would be too stupid to notice the creature as they will stop to mourn the ice "breaking". He claims to be moving the world forward by using this new fuel, citing that the lives of those eaten by the creature were not important. However, the Doctor tells him real value is putting an unimportant life above his own. Sutcliffe notes that the speech would have moved anyone with the slightest bit of compassion; he then adds with an evil smirk "not your lucky day, is it?"
The Doctor and Bill are shoved into a carriage by Sutcliffe, who plans on storing them at the fair until he can detonate the ice; not wishing to risk the duo having warned others to stay away, he plans on detonating at noon after he brings in an elephant to draw in a crowd. Sitting in the carriage, Bill wonders if the Doctor really is 2000 years old; he wonders why she asks. With an impressed smile, Bill asks if it takes that long to be able to make a righteous speech like the Doctor did.
Once at the fair, the Doctor and Bill are tied to a pole near the explosives. Bill thinks she can save them by screaming for help; however, the Doctor tells her not to bother. Ignoring the Doctor, Bill screams for help at the top of her lungs; the Doctor only waits for her to stop with annoyed look. Bill's screams are being drowned out by the cheers of the patrons watching the performances. Once done yelling, Bill asks the Doctor what they should do. He asks her to help him get his sonic screwdriver to cut through the ropes they're in. This also attracts the angler fish. Their guard rushes in and the Doctor hands him the sonic causing the fish to become attracted to him. The Doctor tells him to toss the sonic back, having already untied himself; the man is sucked below by the fish.
Free, the Doctor tells Bill that they have two choices: let the creature suffer for centuries, or free it. Bill points out that it could kill everyone if let go. However, the Doctor tells her that it's her choice; he works for the human race, and will only do something that could drastically change the future of their planet only if he's ordered to do so. Remembering the creature's moans of agony, Bill tells the Doctor to free it. With that, the Doctor tells her that he will, telling her to get everyone off the ice beforehand.
Bill finds Kitty, telling her to spread word the ice is thawing to scare people back to safety. The urchins spread word of the ice breaking and someone falling in, quickly getting everyone to leave. Sutcliffe sees everyone running away, deciding to detonate immediately. However, each attempt to detonate instead breaks the chains holding the creature in place; the Doctor switched the explosives' positions.

Bill watches the creature leave
Sutcliffe enters the tent to find the barrels still intact, and the sonic screwdriver hanging on a wire, jamming the signal. He attempts to hold it, but is startled by the sudden sound of the cracking of the ice. He goes outside to see the creature's fin swimming by; the force of it going by cracks the ice and Sutcliffe falls in, never to be seen again. Bill manages to avoid falling in, thanks to the Doctor; he pulls her up to the docks. The creature swims by, splashing them and avoiding harming anyone. Bill wonders where it will go now; the Doctor believes the fish will end up somewhere cold and try to avoid the human race for the rest of its life. However, she then wonders if they just doomed Greenland. As this is possible, the Doctor promises to check on Greenland in its future to see if the fish lives there now.
Later, Kitty arrives outside Sutcliffe's home with the urchins, telling the children to behave and not steal anything. Bill lets them in, leading them to the dining hall. In the hall, the Doctor is scraping a name off Sutcliffe's will, asking a boy for his name; it's Perry. When Kitty asks why, Bill states that Sutcliffe's "long lost heir" couldn't be Kitty (due to the sexism and racism of the era).
Back in 2017 Nardole enters the Doctor's office at St Luke's University. Placing the tea on the Doctor's desk, he notices that the Doctor is still in period garb. Nardole reminds the Doctor that he promised not to go off-world; the Doctor sarcastically asks if it looks like he's wearing off-world clothes. He tells him that he's returned to his office as promised in his "tea-drinking" clothes. Bill exits the TARDIS, still in her period garb, revealing that the Doctor has broken his oath. He reminds the Doctor of his vow whilst Bill is surprised that googling the sea creature from 1881 turned up no results. The Doctor explains that humans tend to overlook the inexplicable and that the Frost Fair involved a lot of day drinking. He shows her the headlines which detail Lord Sutcliffe's death and, despite the contestion of inheritance, Perry was eventually deemed the legitimate heir.
The Doctor and Nardole soon toss a coin to decide whether the Doctor keeps his vow and remains on Earth, or Nardole leaves him alone. Using a trick he learned from the con artist, the Doctor wins and presumably goes off in the TARDIS with Bill whilst Nardole checks the vault. As he goes to leave, knocking comes from inside, Nardole refuses to let the entity out before hurrying away looking very worried.

- Steven Moffat joked in an interview that the intro to EastEnders was always about a giant snake, a reference towards the view of the River Thames from above, which makes it look like a serpent. [2]
- Spider is one of the few child characters to actually be killed on-screen throughout the history of the program.
- For shots involving the Doctor falling below the ice in his diving gear were created by The Model Unit using a miniature 1/3 scale puppet inspired by a similar effect in James Cameron’s film The Abyss. To create Capaldi's head, Stephen Mansfield was invited back to the production to sculpt the feature. Mansfield had previously worked on the show during the era of Sylvester McCoy, making such creatures as the Destroyer and the Haemovores. The members of the team who worked on the effect, as listed on the Facebook page of the Model Unit, are:

Footnotes
- ↑ Technically, this episode premiered on at least the North American version of iTunes. For around four hours in the late morning/early afternoon of the 29th April, British time, it temporarily replaced Smile on all devices with the ability to access iTunes. AppleTV menus, in fact, briefly showed The Return of Doctor Mysterio as episode 1 of the tenth series and The Pilot as episode 2. Though Smile was listed as the third episode, Apple customers were greeted by Thin Ice when they tried to play Smile. Thus it was possible to see this episode in its entirety in the United States and Canada before the BBC One premiere. Apple restored Smile at about 1205 Eastern, and cut off viewers' access to Thin Ice, even if they were then currently watching it. For more information click here.
