Smile was the second episode of the tenth series of Doctor Who produced by BBC Wales. It reintroduced the idea of robots being "intelligent idiots", to quote the Doctor. In previous stories like Robot, The Mysterious Planet, The Girl in the Fireplace and The Girl Who Waited, the robots all worked under mistaken assumptions as to what their functions were, resulting in deaths and forcing the Doctor's intervention.
It also reused the theme of killing unhappy people, which had previously been seen in the Seventh Doctor story, The Happiness Patrol, where the tyrannical Helen A outlawed anything remotely sad, executed anyone who disobeyed.
The Vardy are shown as a swarm of intelligent beings, capable of reducing people to nothing but bones in mere moments. This makes them a mechanical counterpart to the Vashta Nerada, but only in this ability.
This marks the fourth time in the Revived Series that the Doctor has taken his companion into the future for their second adventure with him. Rose, Amy and Clara had been taken to the future after their first encounters with aliens with the Doctor.
Synopsis
After shaking off Nardole, The Doctor asks where Bill Potts wishes to travel in time. She asks to see the future. Complying, he takes her to see one of Earth's first space colonies, where it's been stated the inhabitants have cracked the secret of perpetual happiness. However, they soon discover that the cause of this "happiness" has a very deadly punishment for not following along.
Plot
Bill has just entered the TARDIS, asking the Doctor what she should do as a passenger. The Doctor tells her that she should know as she's already been on a trip. Bill counters this by stating it's a proper trip this time, asking if there are seat-belts. She sits in a seat, noting that the layout the TARDIS is completely wrong; the seats are too far away from the controls. She wonders if the Doctor can stretch his arms like Mr. Fantastic of the Fantastic Four. The Doctor explains he stands when piloting the TARDIS. Bill mocks him for never thinking to bring the chairs next to the controls.
Bill then asks where the steering wheel is. The Doctor tells her that they have to negotiate with the TARDIS (as it's sentient), as it will not always take them where they wish; often it's the "still point" between where one wishes to go, and where they are needed. (In other words, sometimes the TARDIS does take the Doctor where he wants, but WHEN is up to it.) Hearing a knock, Bill wonders who could be knocking on the TARDIS doors. The Doctor mumbles "mum" and opens the door.
Nardole enters, reminding the Doctor that he made an oath and cannot leave the Earth unless a emergency happens. The Doctor tells Nardole that he's over 2000 years old and sometimes likes to take his TARDIS downstairs instead of walking. Nardole asks why Bill is inside; the Doctor states it's because she isn't anywhere else. The Doctor kindly asks Nardole to make tea. Nadrole agrees and leaves them; he states if Bill wants tea, she have to make her own.
Thinking that the Doctor has changed his mind again, Bill asks if they are heading back to his office, to which the Doctor states will happen, after they've had some adventures; "between here and my office is everything that ever happened or ever will." The Doctor tells Bill to make her choice: past or future. Bill states the future, because she wants to see if it's happy. The Doctor complies, throwing the brake lever and the TARDIS takes off.
In a future human colony planet, a woman is warned not to come back to the city as they are having a problem with their microbots, the Vardy; however, she ignores the warning. The woman on the radio is smiling painfully as her friend asks why she's doing it. Smiling still, she explains that some people have died. The woman is horrified to see her smiling at that, prompting a robot with an emoji-like face screen to frown. The woman tries getting her friend to smile, but is horrified to see the robot is showing a death emoji; a swarm of microbots reduces the women to skeletons as they scream. The emoji screen turns back into a smile.
The TARDIS materialises there later, with Bill asking which direction Earth is in. The Doctor tells her any direction, as space is curved; he asks if she's wanting to go back. Bill states that her mind is "overloading" from time traveling to an alien planet in the future. As they walk towards the city, Bill notes the TARDIS hasn't cloaked itself as something else. The Doctor reminds her that it's stuck; Bill notes that the Doctor must like it enough to have never bother to fix the broken cloaking device. Annoyed, he tells her to let the subject go.
They walk into the city, where the Doctor explains that this place was able to crack the mystery of happiness. Bill then questions the Doctor about what Nardole said. The Doctor explains that something happened a long time ago, and now he has to watch a vault. Bill points out that he isn't right now. However, the Doctor counters that he IS as his time machine can take him back to right when he left. Bill questions him as to whether he considered what could happen if he gets stuck or lost away from the university. The Doctor says he doesn't dwell on these matters, as there's nothing he can do about them in the present.
Seeing the Vardy, the Doctor tells a confused Bill that they are robots, not alien birds. Bill is disappointed with the robots; the Doctor tells her not to say such things, as it's rude. Feeling pain in their ears, Bill wonders what happened. The Doctor shouts they've been fitted with some kind of communication device; bizarrely his voice comes out her ear. Bill notes how wonderful this is; she'll never need her mobile phone again. However, she then becomes concerned about being able to turn off the device when using the loo. The Doctor dismisses her worry, stating if they can be given a communication device without any fuss, "there's probably an app for that."
They come across a robot, which the Doctor says is the Vardy interface. Bill wonders if it speaks; the Doctor says it depends on what factor of language survived into this era. The robot's face smiles. Bill laughs that it speaks emoji. The Emojibot gives them badges that reflect their moods in the form of emojis, which only other people (and not the user) can see.
Placing the badges on, both the Doctor and Bill are surprised that they instantly go to their backs. The Doctor presumes that this is so that seeing one's own emotion on the badge doesn't change it, which would have caused a "feedback loop". Bill questions this, as what if the wearer fancies someone; the Doctor laughs, "Well, I guess you'd have to maintain eye contact with them, then." Bill likes the idea. They head further inside, while Bill's badge shows her happy, the Doctor's shows him as puzzled.
The Emojibot serves cubes of gelatinous blue food. Bill notes it smells like fish; the Doctor isn't pleased by this as he's meet intelligent fish & eating fish would lead to awkward conversations. Bill wonders if the food is safe for them to eat, as she doesn't know if humans are meant to be living here; the Doctor points out that the cutlery is human and only humans speak in emoji. Bill begins eating her cube of food. Seemingly responding to the Doctor's puzzlement, a swarm of Vardy wait outside the building. The Doctor notices there is no livestock, to which Bill is pleased to know that humanity no longer needs to eat animals; instead, this algae-like substance. The Doctor notes that he meet an emperor made of algae once; the emperor fancied him.
The Doctor reiterates that this place is ready for humans to live in, but there is no-one around. Bill compares it the student union, where a place to live is prepared before anyone moves in. Seeing Bill is on to something, the Doctor comes to the conclusion they've just arrived too early; the colonists sent the Vardy ahead of them to prepare the planet for them. If the atmosphere is human-friendly, the Vardy can fix it; the robots can also build someplace to sleep, so the colonists aren't stuck in their ship.
However, Bill notes that the Doctor has two helpings, wondering if there's food sexism in the future; "is this bloke utopia?" The Doctor explains that the Vardy have mistaken him for two people, due to his two heartbeats. Bill is surprised, wondering why the Doctor has two hearts; he retorts "why one?" Amused, Bill wonders if this means he has high blood pressure; he confirms this in a grim tone, suggesting it's troublesome to Time Lords.
The Emojibot continues to escort the Doctor and Bill to a greenhouse outside, where it pollinates plants and an automated system sprays calcium-based fertiliser onto the plants. The Doctor finds a discarded necklace, keeping it hidden from Bill. Seeing a rosemary plant, Bill smells it, remembering there's one outside the student union. She thanks the Doctor for bringing her to the future; she's smelling the scents of home several years into the future.
Noticing that the Doctor's badge has a thinking face, Bill asks the Doctor what he is thinking about, and he replies, suspicious that he is thinking about "a magic haddock". The Doctors discover broken human skeletons being crushed into fertiliser. He realises that these must be the remains of the human party sent in advance of the rest of the colonists. The two try to escape, but the Emojibot shows the Doctor the teary-eyed emoji on his mood badge, changing into the skull-faced emoji as they escape.
As they run, Bill notes that if the robot is chasing them, it's awfully slow. The Doctor tells her that there's a reason for something chasing you to be slow; it doesn't need to be fast. In the centre of a corridor, the Doctor and Bill find themselves surrounded by Emojibots that can sense their fear. The city is full of them, so the robots will catch you eventually. The Doctor wonders why they're being attacked NOW, when they've been there a long time. Realizing something, the Doctor tells Bill to smile using her whole face; she wonders why as the Doctor checks her badge. Seeing Bill's badge change to a smile, the Doctor tells her that smiling has a psychologically effect on one's mood. He further explains that the robots' programming has caused them to make these mistakes; the Vardy were programmed to make people happy. However, they seem to think they need to kill people when they become unhappy.
The Doctor tells Bill that they should give the Emojibots what they want, and smile. As they head to an exit, the Doctor tells Bill to not bother unless she is smiling. The Doctor rells the robots that they've enjoyed their stay. Bill tells him that next time, they should go to Aberdeen or Wiltshire. Agreeing with her, the Doctor and Bill move past the Emojibots, now bearing annoyed faces, but still poised to attack.
They run outside, where an Emojibot grabs Bill's arm. Bill screams in terror, as the Doctor tells her to smile. However, Bill is too scared to fake happiness. Instead, the Doctor sonics the robot's arm, breaking it and freeing Bill. This signals a swarm of Vardies to seemingly emerge from the building's structure itself. They continue running, with the Doctor sure the Vardy will not be concerend with them once they are out of the city.
Once back at the TARDIS, the Doctor tells Bill to remain while he runs back to the city to destroy the Vardies and the city before they kill the incoming colonists, expressing a "childish impulse to blow it up". He defends this action because they cannot leave a death trap operational; if the colonists arrive, they're gonna end up the fertilizer for "the new Garden of Eden". Bill wonders why he can't call a "helpline" to deal with the problem instead, the Doctor runs off, telling her not to look at his browser history. Seeing the Doctor run, Bill heads back outside the TARDIS, reading the sign on the door: "Advice and assistance obtainable immediately"
In the city, the Doctor convinces an Emojibot that he is happy, but his happy-faced badge changes to show a light bulb shortly afterwards. He hears someone breathing on his communication device and realises that Bill has followed him back. He explains to her that the entire city is made out of interlocked Vardy microbots. However, the Doctor believes that the centre of the city houses the spaceship in which the colonists first arrived, comparing it to the Vikings, who lived in their ships until they built new homes.
Finding the entrance to ship, Bill tries to pull the door open. Humorously, the Doctor presses a button that opens the door inward. "Not even locked; they were expecting to live in peace" the Doctor sadly notes. He then suggests locking it behind them, which alerts all Emojibots in the city, whose smiley emojis now incorporate exclamation marks for eyes.
Inside the spaceship, the Doctor comments on the difference between design of the ship interior and the city outside, each designed by "wet brains" (humans) and "dry brains" (Vardies). They come across a map labelling where they are, and the Doctor plans to walk to the engine room in the middle of the ship. He instructs Bill to stay back to guide him through the map, which displays the Doctor's current position. On his way, the Doctor finds all sorts of furniture and artifacts, including the bust of Nefertiti.
Bill asks how the Doctor is allowed to blow up the spaceship without consequences, but he responds that it is a "moral imperative" to destroy the "murder machine" that surrounds them. Bill notices an unexpected empty space surrounding the engine room, but the tannoy of the ship distracts her. Outside, the Emojibots' faces change to skulls as the ship, Erehwon, begins to wake up, and as the Doctor descends into the engine room.

Bill realises she could have followed the Doctor the entire time if she had photographed the map. The Doctor reveals that he had already memorised the map, as Bill protests against his leaving her "out of trouble". Bill follows the Doctor's path, but she stumbles upon a room containing a recently deceased old woman, with a book placed at her feet. Bill finds that the book contains digital images of human history on Earth, continuing past her time and through an apocalyptic war. The Doctor explains that humans evacuated Earth following this conflict, and that this colony must be one of those evacuative ships. He meanwhile fiddles with the engine room controls, trying to reroute the engine's flow into the calorimeter. However, as he tries to do so, the calorimeter begins to rise to its peak, which spells doom for the Doctor.
Bill proceeds to the engine room, but to her shock, finds a boy, which asks, "Are we there yet?" Meanwhile, an Emojibot closes in on the Doctor, who is still waiting for Bill to help him hold the calorimeter tightly while he jams it shut with a spanner. The Doctor sees its reflection in a dial, and smashes the emojibot off the catwalk with the spanner, nearly dragged down himself, only to run into Bill and the confused boy, who asks where everyone else is.

The Doctor is puzzled by this, until he and Bill find that the empty space around the engine room is where the remaining human population is cryogenically stored. One of the stored humans, named Steadfast, wakes up, and the Doctor assertively instructs him to stay inside the ship as the other humans begin to unfreeze behind him. The Doctor explains to Bill that he doesn't have a plan yet, but he acted like he had one to make sure idiots didn't cause more trouble by trying to think up their own plans.
Bill takes the Doctor to the old woman's corpse, and they try to understand history and the woman's role in it. They discover a large number of deaths increasing in numbers since the death of this woman, the first death of the colony. The Doctor realises that it was grief that led to the deaths of all the people. The Vardies, not knowing how to interpret grief (after a loved one has died), so they interpreted it as a threat to happiness that needed to be killed. Subsequently, all the grieving loved ones of every next person killed. In the short period of a day, sadness has become much like a plague. The Doctor again mentions the magic haddock, and produces the discarded necklace, which contains a hologram of the boy waving happily. Bill says that they will find the owner of the necklace when she wakes up, but the Doctor tells her that he found it in the greenhouse, belonging to one of the dead advance colonists. Meanwhile, an Emojibot offers a mood badge to the boy, who is walking outside in the city, looking for his mother. His mood changes to a puzzled emoji.
The waking colonists arm themselves with laser guns to fight the Vardies. Bill tells Steadfast that he needs to listen; he bluntly says he did, now knowing that the Vardy are killing people. The Doctor quickly runs up to Steadfast, explaining "The Vardy want to help you; killing you is just a side-effect.". The colonists take off to destroy the Vardy; the Doctor and Bill run after the colonists to prevent another mass slaughter.
In the city, everyone finds the boy flanked by two Emojibots. The boy asks where his mother is, beginning to cry. Bill tries silencing him into smiling, telling him to admire his new home. The Emojibots grab the boy, ready to kill him; however, Steadfast fires upon the Emojibots. One is damaged and the second's screen begins flashing between two new images. The Doctor realizes that the symbols mean "Rage" and "Revenge". The rest of the colonists begin to fire, as some Vardies break off from the ceiling to attack, and kill a man.
Instead of caring about the attack, the Doctor begins thinking about how the Vardy are reacing; they are registering as under attack. That means they're "alive" AKA sentient. He runs to a broken Emojibot, using the sonic screwdriver on its wiring. The Doctor tells Bill there's a reason he never loses at chess; he has a secret move. Whenever he's about to lose, he kicks over the board and ends the game. Hoping what he's about to doesn't hurt, the Doctor finishes messing with the Emojibot, creating a blinding, disorienting flash throughout the city.
The Doctor tells the story of the fisherman and the magic haddock. A fisherman caught the fish and it offered three wishes in exchange for it's life. The fisherman wished for his son to return from war and 100 gold pieces, but the haddock thinks in a different way (like a robot), instead sending the son's corpse home from the war, along with 100 gold pieces commending his service.
The fisherman then wished that he hadn't wished the first two wishes, pressing the "reset button", which is what the Doctor has done to the Vardies. The Doctor has wiped the Vardies' memories, so they now believe they are the indigenous life forms of the planet. The Doctor tells Steadfast that the Vardies are willing to negotiate with the humans, now considered a migrant race to the planet belonging to the Vardies.
Returning to Earth in the TARDIS, Bill asks the Doctor if the human-Vardy relationship will work. The Doctor replies that it is up to them. Bill asks him if he normally deals with such affairs, acting as an "intergalactic policeman". The Doctor replies that the police box exterior of the TARDIS is a mere coincidence. They land, exactly at the point they left, but when Bill steps out of the TARDIS, it is snowing.
To their shock, elephant is approaching the TARDIS. The Doctor explains that they are in London, not Bristol, and that they are standing on the frozen Thames. Seeing this, the Doctor realizes Bill might have been right about a steering wheel.
