The Two Doctors (TV story)

The Two Doctors was the fourth story of Season 22 of Doctor Who. It was the first appearance of the Sontarans since Season 15's The Invasion of Time. The Second Doctor returned, played by Patrick Troughton, as did Jamie McCrimmon, played by Frazer Hines, both having last appeared in the twentieth anniversary special The Five Doctors. It was the first Sontaran story set on contemporary Earth, Peter Moffatt's last contribution to the show and Robert Holmes' first Sixth Doctor script.

After the success of The Five Doctors, Nathan-Turner was keen to do another multi-Doctor story. He quickly secured Troughton as the returning incarnation. It was suggested the story be set in New Orleans, but Holmes found it to have little merit as a setting and the idea was quashed when funding was pulled. Venice was chosen by Nathan-Turner, but this was too expensive, leaving them with Seville, a Spanish town. Holmes reluctantly agreed to a rewrite, disappointed he would have to cut his jokes about the differences between British and American English. As a vegetarian, Holmes wrote The Two Doctors as an allegory of meat-eating, hunting and butchering.

Synopsis
The Doctor has teamed up with himself before to save lives. This time, he must save his past self in order to ensure his own existence in his present. What could Chessene and dim-witted lackey Shockeye have planned with the Sontarans? Only one thing is known for sure: time will tell.

Part one
The Second Doctor pilots the TARDIS as Jamie McCrimmon laments over the absence of their friend Victoria Waterfield. The Doctor reminds him that she's off studying graphology at the time. Wondering where they're going, Jamie is informed by the Doctor that the Time Lords are sending them on a mission to Space Station Camera in the Third Zone; they've also installed a teleport control on the TARDIS that grants them dual control. Showing the image of their destination to Jamie, the Doctor hears him compare its size to twenty castles. The Doctor explains to Jamie that the station is a research facility and they are here to have a discreet word with Dastari, the Head of Projects. The TARDIS materialises in the station kitchen, where they meet Shockeye, the station cook.

Shockeye is an Androgum, a member of a primitive, emotionally and ethically bestial humanoid race who make up the station's workforce. He is confrontational, angry that a ship has been landed in his kitchen, until the Doctor reveals he is a Time Lord. Suddenly deferential, Shockeye eyes Jamie hungrily and offers to buy him from the Doctor as the main ingredient for a meal. The Doctor, shocked, refuses. He takes Jamie away to see Dastari. As they leave, however, they hear the sound of the TARDIS dematerialising. This is observed by Chessene, an Androgum technologically augmented to mega-genius levels; her appearance has changed because of such - she looks like an attractive human woman. Chessene has plans of her own. They involve someone named Stike, who will be arriving soon, once Shockeye's poisoned meal for the scientists takes effect. She has also taken possession of the Kartz-Reimer module.

The Doctor speaks to Dastari in his office. He explains the Time Lords want Kartz' and Reimer's time experiments ended, as, if the wrong people had access to time travel, it would spell disaster for the entire universe. The Time Lords have an official policy of neutrality, which prevents them from getting directly involved. Because of such, they've sent the Doctor, who has been exiled from their world, to maintain deniability of ever being involved. Dastari introduces Chessene. The Doctor is sceptical that augmentation can change her Androgum nature. He considers such tampering dangerous.

Meanwhile, three Sontaran battlecruisers appear near the station on an intercept course. Before the station's defences are activated, Chessene incapacitates the technician on post and opens the docking bays. Back in the office, the Doctor warns that the distortions from the Kartz-Reimer experiments threaten the fabric of time. Dastari refuses to order them ended. He accuses the Time Lords of not wanting another race to discover the secrets of time travel. The argument grows more heated. Dastari grows faint and falls into a drugged stupor. Energy weapons begin to sound in the corridors and the Doctor orders Jamie to run, as a Sontaran levels a gun at the Doctor.

Somewhere and somewhen else, the Sixth Doctor is fishing while Peri finishes dressing herself after trying to get a tan. He tries explaining that the lake should be full of gumblejacks, a fish that tastes heavenly when cooked just right. The Doctor packs up his fishing pole, chair and umbrella. He tells her it's time to leave. After returning to the TARDIS, Peri is startled as the Sixth Doctor sways and collapses — just as, back on the station, Jamie spies the Second Doctor in a glass chamber, writhing in agony while a Sontaran manipulates controls.

In his TARDIS, the Sixth Doctor awakens in a confused state. He starts talking about jelly babies and a recorder. He has had a vision of himself in his second incarnation being put to death. He realises this is impossible, since he is still alive, but he is also concerned he may have died in the past and only exists now as a temporal anomaly. He decides to consult his old friend Dastari.

The TARDIS materialises on the station. Everything is dark. The smell of decay and death is everywhere. The station computer demands the Doctor leave. When he refuses, it tries to kill Peri and him by depressurising the passageway. The Doctor opens a hatch and drags his unconscious companion to another section.

In Dastari's office, the Doctor discovers the scientist's day journal and the Time Lords' objections to the Kartz-Reimer experiments. He refuses to believe his people are responsible for the massacre. Peri suggests someone is trying to frame the Time Lords to drive a wedge between them and Third Zone governments. They leave the office to enter the service ducts, work their way to the control centre and try to deactivate the computer before it kills them.

On Earth, Chessene, Shockeye and a Sontaran, Major Varl, seize a Spanish hacienda, killing its aged owner, Doña Arana. Varl sets up a beacon for the Sontaran ship. Chessene absorbs the knowledge of the old woman's mind, learning they are in Andalucia just outside Seville. Varl announces Group Marshal Stike of the Ninth Sontaran Battle Fleet is in orbit.

Meanwhile, Oscar Botcherby and Anita approach the grounds. Oscar, an English ex-stage actor who is running a restaurant in the city, is here to catch moths, armed with a net and a cyanide killing jar. Anita and he see the Sontaran ship zoom overhead and through binoculars observe Dastari and another Sontaran carrying an unconscious Second Doctor towards the hacienda. Anita pulls Oscar along, thinking them victims of an aeroplane crash who need help.

In the bowels of the station, the Sixth Doctor tries to disconnect the main circuit to prevent the computer from attacking them again. Suddenly, Peri is attacked by a humanoid in rags. Her cries distract the Doctor. He is hit by a gas trap and falls unconscious, ensnared in the wires.

Part two
Peri knocks out her attacker and frees the Sixth Doctor, who saved himself by shutting off his respiratory passages. He disconnects the computer's circuits. They find that Peri's attacker is a half-delirious Jamie, who has been hiding all the while. Jamie moans that "they" killed the Doctor. Under hypnosis, he tells the Sixth Doctor what has transpired, giving a description that the Doctor recognises as the Sontarans. Returning to the office to examine the station records, the Doctor suddenly sees Peri in the glass tube, writhing in pain.

As he frantically works the controls, the person in the tube changes from Peri to Dastari to the Second Doctor and even to himself. When Jamie and Peri return to the office, the Sixth Doctor explains that what Jamie saw was an illusion designed to make people believe the Doctor was dead and not investigate further; the animator had been left on and captured Peri's image.

This means the Second Doctor is a prisoner. The Sixth Doctor deduces the Sontarans kidnapped Dastari as well. Dastari is the only biogeneticist in the galaxy who can isolate the symbiotic nuclei of a Time Lord, which gives them the molecular stability to travel through time. Given time travel, the Sontarans will be unstoppable. The Sixth Doctor puts himself into a telepathic trance to find his past incarnation. He wakes, having heard the sound of the Santa Maria, the largest of the twenty-five bells at the Great Cathedral of Seville.

In the cellar of the hacienda, Dastari and Chessene set up equipment. The Second Doctor is drugged and passive. Dastari asks why they are on Earth. Chessene says it is convenient for an attack Stike plans for the Madillon Cluster against the Rutan Host and Shockeye wants to taste the flesh of humans. Dastari heaps scorn on Shockeye's primitive urges. He urges Chessene to remember she is beyond those, now.

The TARDIS materialises near the hacienda. Oscar approaches it as the TARDIS crew emerge. He thinks it a real police box and the Doctor and his companions are plain-clothes police officers. Taking advantage of the mistake, the Doctor asks that Oscar lead him to the hacienda.

Dastari plans to dissect the Second Doctor's cell structure to isolate his symbiotic nuclei and give them to Chessene. The Second Doctor calls him mad. He protests that her barbaric Androgum nature and the ability to time travel will mean there will be no limit to her evil. The Sixth Doctor asks Peri to create a distraction at the hacienda's front door while he and Jamie enter the cellar via a passage from the nearby ice house. Peri interrupts Dastari's operation. She poses as a lost American student. Chessene is suspicious, having read thoughts of the Doctor in her mind. Chessene gets Shockeye to bring the Second Doctor through the hall, strapped to a wheelchair, to see if Peri reacts. She does not for she has never seen the Second Doctor. Peri makes her excuses and leaves, but Shockeye chases her anyway, eager for a meal.

Meanwhile, the Sixth Doctor and Jamie are in the cellar. The Doctor examines the Kartz-Reimer module, a prototype time machine modelled on Time Lord technology. He tells Jamie that once the module's briode nebuliser is primed with his symbiotic nuclei — the Rassilon Imprimatur — it will be safe for anyone to use. Unfortunately, the Sontarans have heard him. Outside, Shockeye catches up to Peri. She trips and falls. Shockeye looms over her, muttering with delight...

Part three
Shockeye knocks out Peri and brings her to the kitchen. In the cellar, Stike threatens to kill Jamie unless the Sixth Doctor gets into the module and primes it with his symbiotic print; the Doctor does so. Stike is about to kill Jamie anyway, but Jamie stabs Stike's leg. he and the Doctor run upstairs, where they find the Second Doctor. Before they can release the prisoner and escape, Shockeye shows up with the unconscious Peri. The Second Doctor feigns unconsciousness while the others hide.

While the Sixth Doctor and Jamie watch from their hiding place, Chessene voices her concerns. If a second Time Lord is involved, other Time Lords may come. She has a contingency plan. She asks Dastari to implant the Second Doctor with Shockeye's genetic material, turning the Doctor into an Androgum in her thrall. Then they will eliminate the Sontarans. However, Dastari and Chessene do not know the module is primed and that, outside, Stike is preparing to leave in it once Sontaran High Command has been notified. He will leave no survivors. He orders Varl to set the Sontaran battlecraft's self-destruct mechanism.

Interrupting Shockeye before he slaughters Peri, Chessene has him bring the Second Doctor to the cellar. There, she stuns Shockeye so Dastari can remove his genetic material. The Sixth Doctor revives Peri in the kitchen and ushers Jamie and her away. The Sixth Doctor tells them what he revealed about the Imprimatur in the cellar was not strictly true — he had heard Stike approaching and the speech was for the Sontaran's benefit. The machine worked for the Doctor, but will not for them because the Doctor has taken the briode nebuliser.

Dastari has implanted the Second Doctor with a 50% Androgum inheritance. When Shockeye wakes in a rage, he finds a kindred spirit in the transformed Doctor. They decide to go into the town to try the local cuisine.

In the meantime, Dastari lures the Sontarans into the cellar. Chessene attacks them with two canisters of coronic acid. Varl is killed, but Stike, though wounded, escapes. He tries to use the module, but without the nebuliser, it severely burns him. Stike staggers towards his battlecraft, forgetting about the self-destruct. The ship explodes, taking him with it.

The Sixth Doctor, Peri and Jamie follow the Second Doctor and Shockeye into Seville, hoping to cure him before the change becomes complete and affects the Sixth Doctor as well. Dastari and Chessene are seeking the two of them, knowing that unless the Second Doctor undergoes a second, stabilizing operation, he will eventually reject the Androgum transfusion.

The Second Doctor and Shockeye go to Oscar's restaurant. They order gargantuan amounts of food. When Oscar demands they pay, Shockeye stabs and kills him, just as the Sixth Doctor and the others arrive. Shockeye leaves behind the Second Doctor, who slowly reverts to normal. All of them leave the restaurant to the distraught Anita. Chessene and Dastari arrive to take them back to the hacienda at gunpoint.

Chessene and Dastari find the nebuliser missing. The Sixth Doctor tells them how he primed the machine for Stike. To test the Doctor's claim, they replace the nebuliser and send Peri on a trip with the module and she survives.

Chessene gives Shockeye permission to eat Jamie. The Androgum takes him to the kitchen. Alone for the moment, the Sixth Doctor smugly confirms the Second's suspicions — the nebuliser is sabotaged, with an interface layer so thin it would only work once for Peri. The Doctors retrieve the key to their chains. The Sixth Doctor frees himself first and runs to save Jamie. He encounters Shockeye in the kitchen. The Androgum wounds him with a knife, then pursues him through the grounds, but the Sixth Doctor finds Oscar's cyanide killing jar. He ambushes Shockeye, covers his head with Oscar's butterfly net and presses the cyanide-soaked cotton wool to his face, killing him.

The sight of the Time Lord's blood on the ground is too much for Chessene. She falls to her knees and starts licking it, to Dastari's disgust. He realises that no matter how augmented she may be, Chessene will always be an Androgum. He decides to free the Second Doctor and his companions. When Chessene sees this, she shoots and kills Dastari. She tries to shoot the Second Doctor and Peri as well, but Jamie throws a knife at her, making her drop the gun. Chessene goes into the module, hoping to escape, but the module explodes, disintegrating her molecularly and turning her back into a common Androgum in death.

The Second Doctor uses a Stattenheim remote control — which the Sixth Doctor covets — to summon his TARDIS. He and Jamie say their goodbyes and leave.

The Sixth Doctor and Peri make their way back to their own TARDIS. The Doctor tells her that from now on, it will be a healthy vegetarian diet for both of them.

Cultural references from real world

 * In his collection of business cards of geniuses, the Doctor mentions Archimedes, Brunel, Christopher Columbus, Dante, Da Vinci and Dastari.
 * Oscar and The Doctor quote verses from William Shakespeare's Hamlet
 * The Sixth Doctor recalls having been to Seville before.
 * After the sixth Doctor attempts to make contact with himself by telepathy to get a fix on the second doctor's location, he says it has 'something to do with getting my hair cut' and sings a few bars from the opera 'The Barber of Seville'.

Time travel

 * Ripples in time can be measured on the Bocca Scale (Kartz and Reimer's experimentation measured 0.4).
 * The Doctor talks of the holistic fabric of time, which might have been punctured by the Kartz Reimer experiments.
 * Time travel is impossible without some form of molecular stabilization system: Kartz and Reimer used a briode nebuliser into which the Doctor copies the 'Rassilon Imprimatur', turning the module into a fully functioning time machine.
 * The Doctor states that much of what he said about time travel was for Stike's benefit and consequently not true. Therefore the following 'statements' should be taken with a pinch of salt:
 * The biological make up of Time Lords features symbiotic nuclei, affording protection from molecular break up and symbiotic control of the TARDIS.
 * This protection is extended to other travellers in the TARDIS.

Story notes

 * This story had working titles of The Kraalon Inheritance and The Androgum Inheritance. The Kraglon Inheritance also appears on some BBC paperwork, but this may possibly be a misspelling of 'Kraalon'. Other rumoured working titles are Parallax, The Seventh Augmentment and Creation, but these do not appear in any known documentation.
 * The story opens in black and white, with a scene featuring the Second Doctor and Jamie, which then gradually transitions to colour. This is a homage to Patrick Troughton's era on Doctor Who, which was shot in monochromatic format.
 * This story features Patrick Troughton's final performance as the Doctor.
 * This story, like many of Season 22, was produced in forty-five minute episodes. When sold to other countries such as Australia and America, the episodes were edited into six twenty-five-minute episodes with new cliff-hangers added, Peri's collapse on the space station for Part 1, Anita leading the Doctor to Chessene's hideout for Part 3 and the Doctor struggling against the Androgum genes infecting his timeline for Part 5. Due to these international edits, in some countries this story is arguably the final six-part story instead of The Armageddon Factor or the unproduced Shada.
 * The location shoot in Seville  kicked off production. When the wigs constructed for the guest characters such as Chessene and Dastari were lost in transit, the actors had to be fitted for new wigs in Seville. These Spanish wigs were subsequently used for the studio shoot in England in order to keep continuity. The original wigs are, as far as is known, still missing to this day.
 * Radio Times credits John Stratton (Shockeye) as 'Shockeye o' the Quancin' Grig' for Part One.
 * James Saxon (Oscar) is credited as 'Oscar Botcherby' in Radio Times.
 * The Radio Times programme listing for part two was accompanied by a black and white publicity shot of the Sixth and Second Doctors sitting back to back in the hacienda's olive grove, the latter wearing Androgum make-up, with the accompanying caption "Double trouble with the two Doctors / BBC1, 5.20 p.m. Doctor Who".
 * This is the last serial of the 1963-89 series to be filmed on the European continent, ending an occasional tradition that had begun with TV: City of Death and continued in TV: Arc of Infinity and TV: Planet of Fire. The next such occasion was TV: The Fires of Pompeii, filmed in Italy in 2008. The revived series returned to Spain again for the filming of TV: A Town Called Mercy in 2012, though the story was set in Nevada.
 * This is one of the most violent stories in the series' history, featuring multiple stabbings and knife wounds, blood spillage (human, Time Lord and Sontaran), the attempted cooking and eating of humans and the killing of Shockeye by the Doctor by cyanide poisoning. This is reflected in the serial's mortality rate: Anita is the sole non-Doctor/non-companion character to survive its conclusion.
 * The idea of the Second Doctor being operated on with the intent of removing a unique Time Lord genetic trait was part of Holmes' aborted script for The Six Doctors. In the script, the Cybermen planned to extract a unique organic mechanism from the Doctor and place it in themselves, becoming "Cyberlords".
 * Originally, this story was set in New Orleans and the Androgums, with their obsession with cooking and eating, were created with the city's culinary reputation in mind.
 * Laurence Payne (Dastari) also supplies the voice of the Space Station Camera computer but was uncredited on-screen. (DWM 195)
 * This is the first three-part serial since TV: Planet of Giants.
 * Actress Jacqueline Pearce was well known to the science fiction community for playing the role of the treacherous Servalan in the series Blake's 7, created by Terry Nation. She was a last minute replacement for another actress, for whom Chessene's costume had already been made.
 * "Warts" in the Androgum makeup were made from Rice Krispies.
 * According to Nicola Bryant on the DVD audio commentary, part of the Top of the Pops set was used to construct of the bowels of Space Station Camera.
 * Director Peter Moffatt  and costume designer Jan Wright can be spotted sitting outside the Restaurant in Seville.
 * Location liaison and translator Mercedes Carnegie was rewarded for her work with a cameo as the lady who drops a rose from her balcony in part three. The frivolous dress she wears was actually intended for the character of Anita to wear during her moth hunting trip in the previous two parts, but actress Carmen Gómez refused to wear it, preferring a light summer dress instead.
 * This is the first Multi-Doctor story to not commemorate a major anniversary for the show.

Production errors

 * In some scenes you can see Clinton Greyn's lips moving independently of his Sontaran mask's lips.
 * In some scenes when Varl speaks, his mask's mouth remains closed.
 * When Peri enters the TARDIS after the Doctor's fishing trip, she is wearing different shoes than she was outside.

Continuity

 * The Sontarans previously appeared in TV: The Time Warrior, The Sontaran Experiment and The Invasion of Time. This was to be their final appearance for twenty-three years, until TV: The Sontaran Stratagem.
 * This is chronologically the earliest point in the Doctor's personal timestream that he has been seen to encounter the Sontarans. The Third Doctor demonstrated knowledge of the Sontarans when he encountered Linx. (TV: The Time Warrior)
 * As detailed in World Game, this is the Second Doctor's second mission for the Celestial Intervention Agency. For him, the events of The Two Doctors are set relatively soon after The War Games.
 * Victoria Waterfield is mentioned as off studying graphology, but the Doctor and Jamie will return for her after their mission is complete. However, the novel World Game reveals that this is an entire fiction — a lie implanted in Jamie's mind by the Celestial Intervention Agency.
 * In the opening sequence, the Doctor and Jamie are standing in a console room very different to the one used in the Troughton era. In fact, it was the console room used immediately prior to TV: The Five Doctors. World Game hints that this modern-to-the-Second-Doctor console room — and the Stattenheim remote control — were the result of a "complete overhaul" that the CIA did on his TARDIS as a sort of reward for his good performance in the World Game mission. However, they also installed a teleport control at the same time, over the Doctor's protest.
 * The scene where the Sixth Doctor poisons Shockeye is one of the few times that the Doctor has deliberately taken a life face-to-face. Other examples have included the killing of Mehendri Solon (also using cyanide) in TV: The Brain of Morbius, shooting an Ogron in TV: Day of the Daleks, extinguishing the Primords of Bromley and Stahlman in TV: Inferno, shooting several Sontarans with the De-mat Gun in TV: The Invasion of Time and the shooting of the Cyber-Leader in TV: Earthshock and TV: Attack of the Cybermen as well as the Cyber-Controller in the latter serial. In all cases, these were in self-defence (he also swaps a bomb over blowing up the Graff Vynda-K in TV: The Ribos Operation and sabotages a machine, killing Jaeger in TV: The Mutants along with debate as to whether or not he delibrately kills two guards by pushing them into an acid bath in TV: Vengance on Varos); the First Doctor once mentioned that he only took life when his own was sufficiently threatened. (TV: The Dalek Invasion of Earth)
 * The Sixth Doctor continues a Fourth Doctor tradition of enjoying fishing, last seen in TV: The Androids of Tara and mentioned in TV: The Talons of Weng-Chiang.
 * When the Second and Sixth Doctors come face-to-face, they both say "Snap!", referring to the in which players must say "Snap!" when two of the same card are played. Later, the Tenth Doctor says "Snap!" to the Fifth Doctor when he puts on his "brainy specs" and River Song says "Snap!" to the Tenth Doctor when she shows him her sonic screwdriver. (TV: Time Crash, Silence in the Library)
 * The Sixth Doctor and Peri would once again encounter the Sontarans in Sussex, England in 1872. (AUDIO: The First Sontarans)
 * The First Doctor previously visited Seville in 1587 in the company of Ian Chesterton, Barbara Wright and Susan Foreman. (AUDIO: The Flames of Cadiz)
 * An alternative version of the Doctor had his throat cut by Shockeye while another arrived 30 seconds before Shockeye killed Oscar instead of 30 seconds afterwards. (PROSE: So Vile a Sin)
