'''''Extremis''''' was the sixth episode of [[Series 10 (Doctor Who 2005)|series 10]] of ''[[Doctor Who]]''.

Most notably, the episode revealed that {{Gomez}} was inside [[The Vault (The Pilot)|the vault]] beneath [[St Luke's University]] and explained how Nardole came to travel with the Doctor after the events of ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]''.

The episode is also notably one of the few stories to exclude the Doctor from events occurring in the story. [[Bill Potts|Bill]], Nardole and the Doctor himself never left Earth during the story. Aside from a few selective scenes, the whole episode was set in [[Shadow World|a virtual simulation]] with artificial versions of the Doctor, [[Bill Potts (Shadow World)|Bill]] and [[Nardole (Shadow World)|Nardole]], with the [[Twelfth Doctor (Shadow World)|Virtual Twelfth Doctor]] discovering an upcoming alien invasion, beginning a three-part story trilogy involving the creatures responsible for the virtual simulation, the [[Monk (species)|Monks]]. The Doctor is actually watching the entire adventure, as the events were recorded by his copy and sent to his [[sonic sunglasses]].

== Synopsis ==
The [[Vatican]] asks the [[Twelfth Doctor (Shadow World)|Twelfth Doctor]] to investigate a mysterious book called the ''[[Veritas (text)|Veritas]]''. All who read the ''Veritas'' immediately [[suicide|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 (Extremis)|planet]], an executioner named [[Rafando]] shows the [[Twelfth Doctor]] a mechanism specially 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". {{Gomez}} is then brought in, and is ordered to kneel on a dais.

In the present day, sitting outside [[The Vault (The Pilot)|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 the present, the Doctor is using his [[sonic sunglasses]] to mask his blindness, having modified them to give him a layout of the immediate area in a black and green grid-like view. While still outside the Vault, he 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 (Shadow World)|Angelo]] greets [[Twelfth Doctor (Shadow World)|the Doctor]] as [[Nardole (Shadow World)|Nardole]] enters. The Doctor is told that the [[Pope (Shadow World)|Pope]] has requested a personal audience with him. When the Doctor asks why he did not come there himself, Nardole tells him that he ''is'' there.

In his office, the Doctor is shown a piece of parchment that reads, ''[[Veritas (text)|Veritas]]'', which literally means ''The Truth''. Angelo tells him that an ancient Christian sect translated it, but committed [[suicide]] afterwards. A few months ago it was again translated, but again, those who did killed themselves after the translation. All of the bodies had been recovered, except one.

In Bill's house, [[Bill Potts (Shadow World)|Bill]] has brought a girl named [[Penny (Shadow World)|Penny]] home. [[Moira (Shadow World)|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 apologising. Later, Bill is pouring a cup of tea when she hears the sound of [[The Doctor's TARDIS|the TARDIS]] materialising in her bedroom. When Penny asks what it is, she says it's the pipes. The Pope then steps into 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 tells them that they are 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.

Back 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 five minutes. The figure greets him and reads from [[River Song's diary|a familiar diary]]. The figure pulls back his hood, revealing himself to be [[Nardole]], who had been sent on [[River Song]]'s behalf to prevent him from killing Missy.

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.

On the planet, Rafando announces that the five minutes are over and orders that the sentence is now to be carried out. A tearful Missy asks the Doctor not to kill her, promising she will be good.

In the Haereticum, Angelo shows them the cage where the ''Veritas'' is kept. Suddenly a light shines from a wall with [[Monk (species)|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 [[the Doctor's sonic screwdriver|sonic screwdriver]]. They find the missing translator, a man named [[Piero (Shadow World)|Piero]], in the cage. He tells them he has sent something to somewhere, before running off. A strange clawed hand is then seen next to Angelo's head. Nardole sees that Piero had shot out the lock, as the Doctor realises that Angelo 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 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, but he promises not to read the book. However, once they have gone, 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 the device 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, even knowing it will not change his mind; "Without hope. Without witness. Without reward. I am your friend." The Doctor then pulls the lever, activating the execution mechanism. Missy collapses and 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 onto the wall. Stepping through the light, they find themselves in a corridor where they are greeted by Nicolas who takes them to the cafeteria. 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. The figure tells him that what they are doing is a game, but the Doctor uses his sonic screwdriver to turn off the lights, allowing him to escape with the laptop and with it, the translation.

In CERN, Nicolas shows Bill and Nardole to the cafeteria where he tells 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.

At the Vatican, the Doctor opens the laptop and begins to read the email the translator sent to CERN, but the effects of the device begin to wear off and the figures from the cage surround him. Suddenly, a bright white light flares onto the screen.

In CERN, when Bill asks the reason for the dynamite, Nicolas tells them that they are saving the world. When asked how, he replies that this is not the real world. He 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. Nicolas tells them that this is a "Shadow Test", and apologises to them as they escape and the building explodes.

When they make it back to the hub, Bill notices drops of blood on the floor, and Nardole realises that the projectors are actually projecting the locations and 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 into the empty space but steps through another portal. She finds herself inside the oval office, where the Doctor is waiting. 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 (Extremis)|Shadow People]] who think they are real. The Doctor tells her that he has [[Deduction|deduced]] what it means: an alien race who wish to conquer [[Earth]] are running a simulation to assess the abilities of every person on Earth, especially the ones who were smart enough to realise that the world isn't real. The Shadow Test works by having people say random numbers, and since computers can only generate pseudorandom numbers, two people doing that will say the same ones.

Suddenly, Bill dissolves into pixels, revealing the figure behind her, who tells the Doctor that they have killed him many times. The Doctor tells them that they have fallen into a trap they have 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 having watched the recording, calls Bill and tells her to call [[Penny (The Pyramid at the End of the World)|Penny]] and ask her out.

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 of 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?"

== Worldbuilding ==
=== Time Lords ===
* In addition to [[binary vascular system|two hearts]], [[Time Lord]]s have three [[brain stem]]s.
* 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 [[relapse]]s.
* The Doctor worries that, because he managed to temporarily "borrow" [[eyesight]] from his future self, his future [[regeneration]]s might all be [[blind]], or he might not regenerate at all. However, since it is later revealed that it is a simulation, it has no effect on the real world.

=== Individuals ===
* Pope [[Benedict IX]] made a personal recommendation for [[the Doctor]] in [[1045]]. He remembers Pope Benedict, and recalls that "she was trouble, but she wove a spell with her [[castanet]]s".
* [[Pope (Shadow World)|The Pope]] pays the Doctor a visit in the [[St Luke's lecture hall|lecture hall]].
* [[Angelo (Shadow World)|Cardinal Angelo]] acts as translator for the Pope.
* The Pope is also known as the [[Bishop]] of [[Rome]].
* The virtual Doctor says that the [[Pope]] doesn't "zoom around in the [[Popemobile]], surprising people".
* An [[Italian newspaper (Shadow World)|Italian newspaper]] shows a minor story known as "[[Colossal-Lotto]]" about a lottery winner by the name [[Harrison O'Shea]] in [[Milan]] written by [[Paolo Ferrera]].
* Virtual Bill brings [[Penny (Shadow World)|Penny]] [[Bill Potts' flat|home]] on a [[date]]. Penny runs away after seeing the Pope in Bill's [[bedroom]].
* Virtual Bill thought that virtual [[Moira (The Pilot)|Moira]] would be out with "Harry" tonight, although she is corrected in that he is actually named [[Howard (Shadow World)|Howard]].
* The last emails sent before Piero kills himself were, chronologically, to [[Abramo Tognaccini]] (''We have been tricked by [[the Devil|the devil]]'' – in [[French language|French]]), [[Daryn Mcloughlan]] (''[[Prayer|Pray]] for your family''), [[Phil Bond]] (''Pray for us all tonight''), [[Franco Esposito]] (''The world is not what we think'' – in French), [[Christina Tom (Shadow World)|Christina Tom]] (''Farewell''), [[Kevein Paters]] (''Chapel Day''), [[Albertina Ricci]] (''Pray for us all'' – in French), [[Bill Pullman (Extremis)|Bill Pullman]] (''Thursdays meeting''), [[Peter Dukes]] (''The devil's work has been done''), [[Nicia Russo]] (''We have been tricked''), [[Michael Finch (Extremis)|Michael Finch]] (''Missed meeting''), [[Stefan Anchorage]] (''Farwell<!--sic--> on this earth'' – in French), and, finally, four hours before death, to [[CERN|CERN European Organization for Nuclear Research]], ''VERITAS'', containing the [[Veritas (text)|translated text]].

=== Technology ===
* A [[Time Lord execution machine|machine]] has been arranged to execute Missy.
* The Doctor gets an [[email]] on his [[sonic sunglasses]], which the [[Twelfth Doctor (Shadow World)|virtual Doctor]] has sent from the [[Shadow World]] simulation.
* The Doctor 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 [[year]]s), [[height]] (in [[centimetre]]s), [[weight]] (in [[pound]]s), [[heart rate]] (in [[BPM]]) and [[Body temperature|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.
* The Doctor employs a [[reading aid]] with [[Gallifreyan (language)|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, as 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 [[kilometre]]s, and, to work, requires the [[magnet]]s to be cooled at -271.3&nbsp;°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.
* Piero has a [[laptop]] [[computer]]. He [[email]]s the translation to CERN.
* The CERN employees all have [[Dynamite|TNT]] explosives wired under the canteen tables.
* The countdown to destruction at CERN happens on a flatscreen [[television|TV]].
** A flat screen 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 [[Christianity|Christian]] [[Christian sect|sect]] managed to translate the ''[[Veritas (text)|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.
* [[Benedict IX|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 ===
* Piero had been in the cage a long time and had eaten lots of food, including [[banana]]s and [[sandwich]]es. He also had [[coffee]].
* The CERN employees drink all sorts of [[wine]]s before the end, including [[Chateau Cissac]].

=== 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.

=== Terminology ===
* Bill calls Nardole "secretly a [[badass]]", however, Nardole disputes the assessment, claiming there is "nothing [[secret]] about it".

=== 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 cracker]]s.
* Virtual Nardole relates [[hologram|holographic simulations]] with holographic people to the [[holodeck]] on ''[[Star Trek]]'', "or a really posh [[Virtual reality|VR]] without a [[headset]]".
* Virtual Nardole compares the simulation to ''[[Grand Theft Auto]]''.
* The virtual Doctor likens the inhabitants of the [[Shadow World|Shadow Earth]] finding out they are a simulation and committing suicide as a result to a hypothetical scenario in which "[[Super Mario Bros|Super Mario]] realises he's inside a video game".
* The Doctor mentions ''[[Moby-Dick]]'' and the [[Moby Dick|titular whale]].
* The Doctor owns a [[snakes and ladders]] game which he keeps in the TARDIS.

=== Production errors ===
{{Discontinuity}}
* Outgoing [[email]]s on the [[laptop]] are shown, when in fact the ''[[inbox]]'', rather than sent messages, is open on the left panel. Later, when the Doctor opens it again, the same messages appear, but now in ''sent''.
* The position of Nardole's hood during the scenes of Missy's execution varies between shots.
* The reflection of a cameraman can be seen on the TV at [[CERN]], when the camera pans in on the bomb countdown just before detonation.
* When the Doctor turns the headphones on and is tortured with pain, his eyes are closed, but next shot they are open. Next shot, they have closed again.
* One of the Monks in the Haereticum does not have a Monk's face. Instead, it looks like one of the skulls used in ''[[Heaven Sent (TV story)|Heaven Sent]]'' repainted.

== Continuity ==
* Rafando mentions the tendencies of [[Time Lord]]s to have relapses of life after death. After dying on the operating table, the [[Seventh Doctor]] was still able to regenerate hours later. ([[TV]]: ''[[Doctor Who (TV story)|Doctor Who]]'')
* Virtual Bill mentions how her attempts to change home didn't work out. ([[TV]]: ''[[Knock Knock (TV story)|Knock Knock]]'')
* Missy mentions "domestic bliss on [[Darillium]]", ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'') as "the word among the [[Dalek]]s". ([[TV]]: ''[[The Witch's Familiar (TV story)|The Witch's Familiar]]'') Missy asks what happened, but is met with silence, and gives condolences for his loss. ([[TV]]: ''[[Forest of the Dead (TV story)|Forest of the Dead]]'')
* The Doctor still experiences [[blindness]]. He lost his [[sight]] saving Bill's life in the [[vacuum]] of [[space]]. ([[TV]]: ''[[Oxygen (TV story)|Oxygen]]'')
* The [[Haereticum]] is a library of heretical and forbidden works maintained by the Vatican. Since his [[first incarnation]], the Doctor has also been a patron of the [[Library of St John the Beheaded]], a similar collection also established by the Vatican, which was hidden in London. ([[PROSE]]: ''[[All-Consuming Fire (novel)|All-Consuming Fire]]'', ''[[White Darkness (novel)|White Darkness]]'', ''[[Millennial Rites (novel)|Millennial Rites]]'', ''[[The Empire of Glass (novel)|The Empire of Glass]]'', ''[[Dragons' Wrath (novel)|Dragons' Wrath]]'')
* Virtual Moira goes to the [[pub]]. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')
* The Doctor promises to guard Missy "on my oath as a Time Lord of the [[Prydonian Chapter]]". [[Spandrell]] once referred to the Doctor as a "Prydonian [[renegade Time Lord|renegade]]", and mentioned "Prydonian vows". He said that "when a Prydonian forswears his birthright, there is nothing else he fears to lose". ([[TV]]: ''[[The Deadly Assassin (TV story)|The Deadly Assassin]]'')
* A plaque at [[CERN]] reveals that the [[large Hadron Collider]] "first started up" on [[10 September]] [[2008]]. [[Jack Harkness]] was present, with his [[Torchwood Three]] team of [[Gwen Cooper|Gwen]], [[Ianto Jones|Ianto]] and [[Martha Jones|Martha]], when this first test opened a portal to another reality, through the LHC, and let out some [[neutron eater]]s. ([[AUDIO]]: ''[[Lost Souls (audio story)|Lost Souls]]'')
* The [[Third Doctor]]'s companion [[Liz Shaw]] joined CERN after leaving [[UNIT]] in the [[1970s]]. ([[PROSE]]: ''[[Country of the Blind (short story)|Country of the Blind]]'')
* The Doctor complains about the book ''[[Moby-Dick]]'', and suggests it would help to be tied down to a chair, to get through it. The Seventh Doctor previously told [[Ace]] he tried over a hundred times, but could never get past the first ten pages of the book. ([[PROSE]]: ''[[Sunday Afternoon, AD 848,988 (short story)|Sunday Afternoon, AD 848,988]]'') On the other hand, the [[Sixth Doctor]] stated that [[Herman Melville]] was one of his favourite authors and disliked that [[Evelyn Smythe]] found him to be pompous. ([[AUDIO]]: ''[[Bloodtide (audio story)|Bloodtide]]'')
* The Virtual Doctor sits in the [[President of the United States|President]]'s chair in a holographic recreation of the [[Oval Office]]. The [[Eleventh Doctor]] previously did just that in the real Oval Office. ([[TV]]: ''[[The Impossible Astronaut (TV story)|The Impossible Astronaut]]'')
* The Virtual Doctor uses the [[sonic sunglasses]] to send a message. The Doctor has used them to get out of an impasse before. ([[TV]]: ''[[Before the Flood (TV story)|Before the Flood]]'') He also used them to summon reinforcements on Gallifrey. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')
* The Doctor was previously aided by a virtual copy of himself. ([[COMIC]]: ''[[A Life of Matter and Death (comic story)|A Life of Matter and Death]]'')
* Bill uses the word "wizard" to describe the Doctor. [[Donna Noble]] previously used the phrase in a similar manner, ([[TV]]: ''[[Turn Left (TV story)|Turn Left]]'') as did the [[Tenth Doctor (Journey's End)|Meta-Crisis Doctor]]. ([[TV]]: ''[[Journey's End (TV story)|Journey's End]]'')
* The Doctor previously encountered a copy of Earth, used by [[Kraal (species)|its creators]] to practice invading, though it only consisted of [[Devesham|a single village]]. ([[TV]]: ''[[The Android Invasion (TV story)|The Android Invasion]]'')
* Rafando reveals that Time Lords have in addition to two hearts, three brainstems. Missy previously told UNIT to deploy 8 snipers to target her organs, "Three for each heart and two for [her] brainstem", to kill her instantly without triggering her regeneration so that Clara would feel safe talking to her. As she did not mention her third brainstem, the snipers in the episode would still have been unable to prevent her regeneration.
