Extremis was the sixth episode of the tenth series of Doctor Who produced by BBC Wales.
Most notably, the episode revealed that Missy was inside the vault beneath St Luke's University and explained how Nardole came to travel with the Twelfth Doctor after the events of The Husbands of River Song.
The episode is also notably one of the few stories to exclude the Doctor from event occurring within the story; as Bill, Nardole and the Doctor himself never left Earth during the story. Aside from the beginning, flashbacks with Missy and the end the whole episode was set in a virtual simulation with artificial versions of the Doctor, Bill and Nardole, with the Virtual Twelfth Doctor discovering an upcoming alien invasion, beginning a three part story arc involving the creatures responsible for the virtual simulation, the Monks.
To simplify things, in a bizarre twist, the Doctor is actually watching the entire adventure with the viewers, as the events were recorded by his copy and sent to his sonic sunglasses. A similar event happened in the pre-title sequence of Before the Flood, where the Doctor is explaining how the bootstrap paradox works directly to the camera.
Synopsis
The Vatican asks the Twelfth Doctor to investigate a mysterious book called the Veritas. All who read the Veritas immediately kill themselves. When a translation of the Veritas is leaked online, the Doctor must face up to the inevitable truth...
Plot
On a distant planet, an executioner named Rafando shows the Twelfth Doctor a mechanism especially designed for killing Time Lords. He then tells him that after the execution, the body will be placed in a quantum fold chamber in case of "relapses". Missy is then brought in, and is ordered to kneel on a dais.
In the present day, sitting outside the Vault, the Doctor talks to Missy, who is inside, saying that no one can know that he's blind.
Back on the planet, while the Vault rises from the lake, Rafando announces that the chamber is prepared. Missy begs the Doctor to let her live, while he places his hand on a lever.
In order to help mask his blindness, the Doctor has modified his sonic sunglasses to give him a layout of the immediate area (in a black and green grid-like view). Back outside the Vault, the Doctor gets an email titled Extremis on the glasses. Intrigued, he opens it.
In the lecture hall, 15 men file in through the back door. Angelo greets the Doctor as Nardole enters. The Doctor is told that the Pope requested a personal audience with him. When he asks why he did not come there himself, Nardole tells him that he is here. The Doctor apologizes saying, "The Pope doesn't zoom round the world in the Popemobile surprising people. Why would you do that?"
In his office, the Doctor is shown a piece of parchment that reads, Veritas, which literally means The Truth. Angelo tells him that an ancient Christian sect translated it, but committed suicide after translating it. A few months ago it was again translated, but again, all of them killed themselves after the translation. All of the bodies had been recovered, except one.
In Bill's house, Bill has brought a girl named Penny home. Moira, thinking that she has brought a "Poor terrified man home" tells her that she has very strict rules about men, before seeing Penny, and apologizing. Later Bill is pouring a cup of tea when she hears the sound of the TARDIS materializing in her bedroom. When Penny asks what it is, she says it's the pipes. The Pope then steps in the room and speaks rapidly in Italian before going back to the bedroom. Bill excuses herself and enters her bedroom where she sees the clergymen. Penny sees them, and freaking out, flees. Bill turns to them and says "You're all going to hell."
In the TARDIS, Bill angrily berates the Doctor for ruining her date, while he has Nardole explain what is happening to her. Angelo tells The Doctor that the Pope had given him an offer for confession that he had refused and that the offer still stands as he prepares a device to temporarily restore his sight.
On the planet, Rafando asks if the Doctor requested a priest as a cowled figure approaches. As the figure gestures to him to approach, Rafando checks the Fatality Index and says that divine intervention is allowed for 5 minutes. The figure greets him and reads from a familiar diary. The figure pulls back his hood saying that his missus would not approve, revealing himself to be Nardole, who had been sent on River Song's behalf to prevent him from killing Missy, saying "Warning, I have full permission to kick your arse."
At Vatican City, Nardole and the Doctor discuss why his blindness should be kept a secret before exiting the TARDIS. Angelo shows them to the entrance to the Haereticum, a portrait of the Pope Benedict IX, which is accessed by turning a candle. Angelo orders them to stay close because the layout is supposed to confuse the uninitiated.
At the planet, Rafando announces that the 5 minutes are over as Nardole pulls down his hood. Rafando orders that the sentence is now to be carried out. Missy asks the Doctor not to kill her, promising she will be good, nearly crying.
In the Haereticum, Angelo shows them the cage where the Veritas is kept. Suddenly a light shines from a wall with a figure in the centre, before fading to nothing. Angelo goes off to check the walls for a breach, as the Doctor takes out his sonic screwdriver. They find the missing translator, named Piero in the cage. He tells them he has sent something to somewhere, before running off. A strange clawed hand then seen next to Angelo's head. Nardole sees that Piero had shot out the lock, as the Doctor says so much for their forbidden library to Angelo, who has vanished. In the cage, Nardole and Bill see Piero's laptop, which had been left behind. Checking it, they find out that he had mailed a copy of the translation to CERN. As Bill says that it is promising that one person read the Veritas and lived, a gunshot is heard and the Doctor's Sonic Sunglasses (Which he is using to see) register his life signs dropping. The Doctor orders them to check on Piero, as the sunglasses register life signs terminated. Nardole and Bill accuse him of trying to get rid of them. He promises not to read the book as they leave. He then opens the Veritas, takes out the device and attaches electrodes to his temples.
In the library Nardole talks with Bill as they walk through the corridors. They find a hand holding a gun, confirming Piero's death. The same light is then seen again. Nardole realises that it's a portal to somewhere. Curious, they step through.
In the cage the Doctor asks for help from Angelo as a sinister shadow is cast on a bookcase. He wonders how it will work: it will either temporarily restore his sight, or it will burn out his brain. He activates it and collapses.
On the planet Missy tells the Doctor that she is his friend. When he tells her that it does not matter, she tells him she knows it does not matter saying, "I know it doesn't. I know I'm going to die. I have to say it. The truth. Without hope. Without witness. Without reward. I am your friend." The Doctor then pulls the lever, causing lightning to arc out of the spheres on the top of the 4 columns on the dais and strike Missy. Missy collapses and dies as the Doctor swears to guard her body in the Vault for a thousand years.
In a 5-sided building, Nardole, and Bill exit a broom closet, where they are seen by a woman. She asks if they have clearance for floor 3. Asking where they are, the woman tells them they are in the Pentagon. Nardole and Bill retreat back to the closet, where they find themselves in a hub, with projectors arranged in a semicircle which project light on the wall. Stepping through the light, they find themselves in a corridor where they are greeted by Nicholas who takes them to the cafeteria, as they pass a sign that says CERN.
In the cage, the Doctor opens his eyes to find that his sight has been restored. As he wonders about the impact on his regeneration cycle, the same figure seen in the light appears. He asks for its help as it buckles leather straps around him to restrain him. The Doctor notices there are more of them as the figure closes the Veritas and takes it while the Doctor complains. The figure tells him that what they are doing is a game. The Doctor says "Good, because I win." and uses his sonic screwdriver to turn off the lights as the figure yells his name. The figures restore them, but the Doctor has escaped with the laptop, and with it the translation.
In CERN Nicolas shows them to the cafeteria where he tell the personnel to give their last orders. He tells Bill and Nardole to look under the tables. There they find that the personnel have strapped dynamite to the table legs.
In a corner the Doctor opens the laptop and begins to read the email the translator sent to CERN. Suddenly, the effects of the device begin to were off as the figures surround him. Suddenly a bright white light flares onto the screen.
In CERN, when Bill asks why they are doing that, Nicholas tells them that they are saving the world. When asked how, he replies that this is not the real world. He says that the have not read the Veritas. Nicholas tells both of them to pick a random number and to say it at the same time. When they try, they both say the same number. Nicholas tells them that is a "Shadow Test", and apologizes to them as they escape and the building explodes. As they arrive in the hub Bill notices drops of blood on the floor. Inside Nardole realises that the projectors are actually projecting the locations. To his horror, he figures out that the world is really a holographic simulation. To see if he is right, he steps into the space between projections causing him to dissolve into pixels.
Bill starts to reach out to the space, but steps through another portal. She finds herself inside the oval office. The Doctor reveals that he had listened to the translation, and that it tells of a demon, who wished to conquer the world, and to do that, he created a Shadow World that has Shadow People who think they are real. The Doctor tells her that he has deduced what it means. He tells Bill that it means that an alien race who wished to conquer Earth ran a simulation to assess the abilities of every person on Earth, especially the ones who were smart enough to realise that the world wasn't real. The Shadow Test works by having people say random numbers. Since computers can only generate pseudorandom numbers, two people doing that will say the same numbers. He tells her that people kill themselves to escape the simulation. Suddenly, Bill dissolves into pixels, revealing the figure behind her. The figure tells him they have killed him many times. The Doctor tells them that they have fallen into a trap they had created: their simulation is too good. He then reveals that since he is linked to the sonic sunglasses, they will have a memory print of the last few hours. He then emails the recording to the real Doctor.
In the real world, the Doctor, after finishing Extremis, calls Bill who tells him she is doing the essay he told her to do. He tells her to call Penny that night. He then tells Missy, that she had told him she was his friend.
On the planet as the executioners go to the dais to take Missy's body away, she wakes up and pushes them away. The Doctor reveals that he had sabotaged the execution machine into knocking Missy out instead killing her. After scaring the executioners away by tricking them into accessing his record of fatalities, the Doctor has Nardole help him move Missy to the Vault.
Outside the Vault, the Doctor asks Missy how he can save his friends when he is blind, saying "How can I save them when I'm lost to the dark?"

Time Lords
- Time Lords have two hearts and three brain stems.
- One stipulation of the Fatality Index is that a death sentence of a Time Lord must be carried out by another Time Lord. That Time Lord must also swear an oath to guard the condemned's body for 1000 years in case of relapses.
- The Doctor worries that, because he managed to temporarily "borrow" eyesight from his future self, his future regenerations might all be blind, or he might not regenerate at all. However, since it is later revealed that it is a simulation, it had no effect on the real world.
People
- Pope Benedict IX made a personal recommendation for the Doctor in 1045. He remembers Pope Benedict, and recalls, "I knew she was trouble, but she wove a spell with her castanets."

Technology
- A machine has been arranged to execute Missy.
- The Doctor gets an email on his sonic sunglasses, which the virtual Doctor has sent, from within the Shadow World simulation.
- The Doctor also uses his sonic sunglasses to scan people's data, as he cannot see them.
- Data the Doctor can detect are:
- Gender (including male and female)
- Age (in years)
- Height (in centimetres)
- Weight (in pounds)
- Heart rate (in BPM)
- Temperature (in degrees Celsius)
- He can also get a sense of the architecture around him, again using the sonic sunglasses as visual aid. However, the glasses psychically "project" a vector map of the surroundings and do not actually show him what his eyes would see if they worked, which explains how he cryptically asks Nardole to describe or explain things that he can't see, including text and projected beams of light.
- Data the Doctor can detect are:
- The Doctor employs a reading aid with circular Gallifreyan script on it, which he hopes will temporarily restore his sight. He confirms that it's deadly.
- Bill notes that the Haereticum has WiFi, and the Doctor says of course it does; it's a library.
- According to a plaque at CERN, its Large Hadron Collider, which was first tested on 10 September 2008, is the world's largest and most powerful particle accelerator. It has a diameter of 27 kilometres, and, to work, requires the magnets to be cooled at -271.3°C—a temperature colder than outer space. To achieve this, much of the accelerator is connected to a distribution system of liquid helium, to cool the magnets, as well as to other supply services.
- The translator has a laptop computer.
- He emails the translation to CERN.
- The CERN employees all have TNT explosives wired under the canteen tables.
- The countdown to destruction at CERN happens on a flatscreen TV.
- A flatscreen is seen in the White House, as well.
Organisations
- CERN is the largest particle physics laboratory on the planet.
- The Pentagon is the headquarters of the United States Department of Defense, located in Arlington County, Virginia.
Religion
- An early Christian sect managed to translate the Veritas before all committing suicide.
- The Veritas is older than the Catholic Church itself.
- Suicide is understood to be a mortal sin in Catholicism, leading one to hell.
- The Pope hopes for God to help the Doctor on his quest.
- Pope Benedict said that the Doctor was "more in need of confession than any man breathing", but when the offer was made, the Doctor replied "it would take too much time".
- The Doctor says that religion is "designed to confuse the uninitiated", as Angelo says of the layout of the Haereticum.
Food and beverages
- The man in the cage had been there a long time and eaten lots of food, bananas and sandwiches included. He also had coffee.
- The CERN employees all drank all sorts of wines before the end. Chateau Cissac included.
Locations
- A long time ago Nardole told the Doctor that he followed him from Darillium and that he has full permission from River Song to kick his arse.
- Nardole tells Bill that the Vatican is in Rome, which is in Italy.
- The Haereticum contains a cage with the Veritas locked inside.
- A total blackout has occurred at the White House. The Doctor confronts a Monk in the Oval Office.
Weapons
- Piero has a gun that he uses to kill himself.
Culture
- Virtual Bill exclaims "Harry Potter!" upon seeing the Haereticum for the first time. In response, the Doctor chides her for using bad language.
- Virtual Nardole says that the Doctor and Angelo would be "wizard" at writing Christmas crackers, when, together, they say, "Truth in the heart of heresy" / "And death in the heart of truth".
- Virtual Nardole relates holographic simulations, with holographic people to the holodeck on Star Trek, "or a really posh VR without a headset".
- Virtual Nardole compares the simulation to Grand Theft Auto, and the virtual Doctor likens the inhabitants of the Shadow Earth finding out they are a simulation and committing suicide as a result to a hypothetical scenario in which "Super Mario realises he's inside a video game".
- The Doctor mentions Moby-Dick and the titular whale.
- The Doctor owns a snakes and ladders game which he keeps in the TARDIS.
- Upon seeing the Monks, the Doctor pokes fun at the saying that no one looks good in the morning.
- Many of the simulated people took the Shadow Test to confirm they were not real.
