"Thin Ice" is the third episode of the tenth series of the British science fiction television series Doctor Who. It is written by Sarah Dollard and was broadcast on 29 April 2017 on BBC One. "Thin Ice" received mostly positive reviews from critics, with many labelling the topic of racism in the episode as well-executed.
The Doctor and Bill Potts visit the last great frost fair in London 1814, but they soon find that something sinister is lurking below the frozen Thames.

Synopsis

The Twelfth Doctor and Bill find they have arrived in London in 1814, in the midst of a frost fair on the frozen Thames. After dressing in period garments, they take time to explore it, unaware the TARDIS sensors have identified a large life form, a kilometre long, under the ice.
The Doctor's sonic screwdriver is stolen by Spider, one of several orphan pickpockets led by Kitty. The Doctor and Bill chase down Spider and Kitty away from the fair. There, glowing lights under the ice encircle Spider's feet and before the Doctor can save him, Spider is pulled through the ice. Bill is troubled by the Doctor's lack of remorse for Spider's death. They track down Kitty and learn they have been paid to bring more people to the fair, with some having gone missing.
The Doctor and Bill get into diving suits and purposely let the lights take them; the lights belong to strange fish, and they find a giant sea creature ensnared by chains, which has eaten Spider and others. Returning to land, they learn from Kitty that their benefactor is the wealthy Lord Sutcliffe. Sutcliffe affirms his family has used the creature to amass a fortune by feeding it victims then collecting and selling its waste as a super powerful replacement for coal. Fearing the Doctor knows too much, Sutcliffe sends the Doctor and Bill to be eaten, while he rigs a bomb to cause the ice to shatter with maximum possible casualties for fish food.
The Doctor and Bill escape, and while Bill works with Kitty and the other orphans to clear people off the ice, the Doctor takes the bomb and places it on the creature's chains. When Sutcliffe sets off the bomb, the creature is able to swim free and Sutcliffe is lost in the freezing water. The Doctor rewrites the deed to the Sutcliffe mansion and its staff to the orphans, allowing them to live there as long as they want.
They return to the present, where Nardole scolds the Doctor for breaking his oath to stay on Earth. Bill finds from old newspapers that the orphans lived a fulfilling life, though surprised there was no mention of the sea creature. Nardole, while checking the Vault beneath the University, hears something behind it knock repeatedly and says he will only let it out with a proper request from the Doctor.

Continuity

The Doctor mentions that he has attended Frost Fairs before. In "A Good Man Goes to War", River Song says that the Eleventh Doctor took her to the 1814 Fair for her birthday, where they were serenaded by Stevie Wonder. The First Doctor took Vicki and Steven to the 1814 fair in Frostfire, where they encounter Jane Austen. The Twelfth Doctor took Clara Oswald to a frost fair in the 1890s in the novel Silhouette, after promising to take her to one of them in "The Caretaker".
"Doctor Disco" is the same name the Doctor used when leaving Clara a voice message in "The Zygon Invasion".

Outside references

The episode features a visit to the 1814 frost fair, the last one to be held between Blackfriars Bridge and Old London Bridge, which caused the water flow in the Thames to slow enough to allow it to freeze. As part of a stunt during that fair, replicated in this episode, an elephant was led across the frozen Thames.
During one scene with the orphans, the Doctor reads them "The Story of Little Suck-a-Thumb" from Heinrich Hoffmann's Struwwelpeter, published in 1845.
Dollard unconsciously named Lord Sutcliffe after Dr Donald Sutcliffe, a character in the Hannibal episode "Buffet Froid", as she was writing Hannibal fan fiction at the same time as the "Thin Ice" script. She said that she feels Donald Sutcliffe could be a descendant of Lord Sutcliffe's family, as the characters are similarly "selfish and twisted".

Critical reception

"Thin Ice" received positive reviews from critics, with many labelling the topic of racism in the episode as well-executed. "Thin Ice" holds a score of 94% on Rotten Tomatoes, the site's consensus reading ""Thin Ice" uses a light touch and timely themes to bolster an episode driven more by character development than high-stakes drama."
Alasdair Wilkins of The A.V. Club awarded the episode a grade "A", crediting Dollard's writing as "brilliant" and being "a story and script worthy" for the Doctor and Bill. It was also followed by stating that 'there's much to celebrate about this episode'. Wilkins also praises the episode's direction, despite it echoing previous stories from the show's past. "Thin Ice" was summed up as a fun episode, stating "that's as good an indicator as any of Doctor Who at its best".
Nivea Serrao of Entertainment Weekly also praised the episode, praising Bill and her reaction towards her surroundings and to the realisation of the Doctor and how he had seen and caused a lot of death. She also praised how the episode treated the issue of racism in the past, and awarded the episode a B+ grade.
However, Kathleen Wiedel of TV Fanatic gave the episode only 3 stars out of 5, stating that the episode "really strayed too far into whole plot references to be altogether enjoyable for its own sake", how previous and similar episodes have already used the "humans are the real monsters" trope, and the lack of impressiveness at Bill's outrage at the Doctor's inability to save everyone all the time.
Scott Collura of IGN gave the episode an 8.2/10, looking at the structure of the story, stating that the episode follows the same pattern that the previous two used, another a one-off that shares similarities to the classic era. He also praised the fact that as "Bill wades deeper into the exciting insanity of the Doctor's lifestyle, she also realizes that it's not all fun and games". Daniel Jackson from Radio Times gave the episode a full 5 stars, praising the story for its multi-layered structure and exploring the hidden depths in the characters. He too commented on how Sarah Dollard explored the characters and how she "examines his moral code; the ideals he aspires to and the crimes and misdemeanors he's prepared to indulge."
