Dark Water (TV story)

Dark Water was the eleventh episode of the eighth series of Doctor Who produced by BBC Wales. It saw the return of the Cybermen and, and the Twelfth Doctor's first encounter with both. The events of the episode centred around the sudden and unexpected physical death of Danny Pink after a fatal accident, his transition into an existence beyond his body and the effect his bodily demise had on Clara Oswald. The story also explored the concept of an engineered afterlife, and revealed the identity of the victim unintentionally murdered by Danny when he was still a soldier.

Dark Water showed an important aspect of the Time Lord's regeneration process that had been mentioned before, but never seen before on screen: the possibility for a change of gender to occur. Missy, a mysterious figure throughout the series, was revealed to be the first female incarnation of the Master, showing for the first time in the history of the series a Time Lord, who had been portrayed by male actors, now being portrayed by a female actor.

This was also the first encounter between the Doctor and the Master since The End of Time, before they regenerated into their next incarnations, though while the cause of the Tenth Doctor's regeneration was shown, it's not revealed in Dark Water or Death in Heaven when the previously male Master had regenerated, nor how she had escaped the pocket dimension that held Gallifrey.

Dark Water, and its follow-up episode Death in Heaven, will be shown in cinemas in 3D as a two-night event on the 15th and 16th September as a run-up to prepare for Series 9. It will be followed by a prequel scene to the ninth series. For the time being, this screening is only to be shown in America.

Synopsis
When Danny is involved in a terrible accident, Clara and the Doctor travel to a mausoleum where the dead are not all that they seem...

Plot
Clara is ready to confess to Danny the adventures she's been having with the Doctor, despite telling him she wasn't. She's about to tell him over the phone, when Danny steps out into the road and is killed by an oncoming car. Unable to deal with her grief, Clara calls the Doctor for help with the intention that he'll change events.

The Doctor picks up Clara asking her where she wants to go, almost immediately sensing something is wrong. She asks the Doctor to take her to a volcano, all while collecting up the TARDIS keys that are hidden in the console room. After the Doctor sets the destination, Clara uses a sleep patch on him.

The Doctor seemingly wakes on a volcanic planet, and Clara tells him what's happened and that she is holding the seven TARDIS keys hostage. Clara then reveals that she knows lava can destroy them and if the Doctor doesn't let her try to save Danny she'll throw them all into the crater in order to prevent the Doctor from ever re-entering the TARDIS, proving that she's serious by throwing one straight away. The Doctor point-blank refuses to save Danny since his death is part of her personal timeline, trying to take control of the situation by telling her to throw another key in the lava. Clara then throws all but one in, and when the Doctor still won't help she throws the last in before suddenly being overcome by the enormity of what she's done. The Doctor then reveals that she didn't actually knock him to sleep (the two are still in the console room), and this has been a telepathic test to see how far she'd be willing to go to be with Danny again. Seeing the extremity of her desire to see him, the Doctor agrees to do everything he can and connects her to the TARDIS' telepathic circuits, as her timestream's connected to Danny's. The TARDIS takes them to wherever she thinks Danny now is.

Danny wakes-up in the Nethersphere, and is greeted by Seb, who informs him of his death.

The TARDIS has taken the Doctor and Clara to the 3W, where they see skeletons seated in watery graves. They’re greeted by Missy. Stating that he clearly didn't receive the formal advance materials, she kisses the Doctor, and claims to be a Mobile Intelligence Systems Interface. Missy lets the Doctor feel her heart, evoking a reaction of quiet surprise from the Doctor.

In the Nethersphere, Seb asks Danny if he's ever killed someone, due to a request from someone Danny could have killed in the army. Remembering his "bad day", the child Danny accidentally killed is revealed to him.

Chang reveals the dark water to the Doctor and Clara. When submerged, only organic matter can be seen – the skeletons are inside something else, hidden by the water.

Danny meets with the child, who runs away when Danny tries reaching out to him. He and Seb hear a man screaming, which Seb explains to mean he left his body to science.

Chang then explains to the Doctor and Clara that the 3W was established after a discovery from television static, that their founder, Dr Skarosa, translated to be distant voices. Believing them to be the voices of the dead, Skarosa isolated some of them. Chang plays a recording of the voice that inspired 3W's founding: “Don’t cremate me”. Chang tells them the dead are still conscious, and aware of everything that happens to their body.

Seb is explaining the same to Danny, who constantly feels cold because he’s still connected to his body, which is being kept in a cold place.

The Doctor states that the dead don't come back, and Chang establishes a communication signal to the Nethersphere, and Clara is able to speak to Danny, with Seb's assistance. The Doctor tells to Clara to ask Danny questions only to which would he know the answer.

Missy activates the tanks, and the skeletons stand. When Chang and the Doctor arrive, Missy reveals she was only pretending to be an android, and kills Chang. As the tanks begin to empty, the Cybermen are slowly revealed.

Clara asks Danny to name the restaurant of their first date – he can't remember.

Missy shows the Doctor the Nethersphere, which is a Matrix data slice housing minds of the deceased in edited forms, while their bodies are used for Cyber-conversion. The Doctor knows the Nethersphere (actually a small sphere within 3W) which is containing the neural patterns is actually Gallifreyan technology, and Missy reveals that she is indeed a Time Lord, or rather a Time Lady as she prefers to be called. The Doctor asks her which Time Lady she is – she's the one he "left for dead", without expecting her to "find [her] way back". The Doctor runs out of the 3W, which is St Paul's Cathedral.

Clara asks Danny more information about her and tells him that if he is Danny, she is determined to find him in the netherworld and threatens to hang up if he says "I love you" one more time instead of answering her questions. Danny tells Clara she must continue her life and not follow him; he repeats the same words for the last time and she disconnects the communication signal. Seb gives Danny the option to delete himself, which would relieve him from the surge of emotional trauma from his call with Clara.

Back in 3W, Clara turns around to see a fully-revealed Cyberman in the water tank. The Cybermen activate, and begin marching down the steps of St Paul's Cathedral. The Doctor yells at civilians to run away, but he’s dismissed as an angry Scotsman. The Doctor demands that Missy tell him who she truly is, and Missy reveals that her name is short for "Mistress" as she couldn't keep calling herself by her previous title... the Master. The Doctor initially reacts with disbelief that quickly turns to horror when he realises she is telling the truth and his old nemesis has returned.

In the Nethersphere, Danny is on the verge of disconnecting himself, and sees the child he killed reflected on the screen of the iPad he holds.

Story notes

 * The Cybermen walking from St Paul's Cathedral and through the London streets emulates a similar scene in the same location in the TV story The Invasion.
 * This episode marks the first on screen instance of a Time Lord changing gender through regeneration, although the possibility had been alluded to in The End of Time, The Doctor's Wife and The Night of the Doctor. Notably, the only time the Doctor had indicated that he may change genders had been when he was recovering from regeneration, a state in which his mental stability is temporarily diminished.
 * The Radio Times programme listing was accompanied by a small colour head-and-shoulders photograph of Missy and the Doctor, with the accompanying caption “ Doctor Who / 8:15 p.m. Missy and the Time Lord come face to face at last – what will the outcome be?”
 * The Hyperscape Body Swap Ticket used to get Clara and the Eleventh Doctor into the Doctor Who at the Proms is shown on Clara's bookshelf among her sticky notes. Discounting the sticky note references to the Paternoster Gang, whom Clara had also encountered in Series 7, and one reading "Impossible Girl" (which was a plot element in TV: Deep Breath), the ticket is the only item exclusive to the Eleventh Doctor era visible on Clara's notes, though the camera does not focus in on all the stickies.
 * When the Doctor hands Dr. Chang the psychic paper, it says that he is from the government and Chang questions the amount of swearing on the paper. The Doctor responds with "I've got a lot of internalized anger." Peter Capaldi is well known for his role as the foul-mouthed Malcolm Tucker in The Thick of It and its spin-off film, In the Loop.
 * This episode marks the first use of the term "Time Lady" in the revived series.
 * At a Royal Television Society event, Steven Moffat revealed a decoy version of Missy's reveal in the episode was shot in case any members of the public overheard: “You know who I am. I’m Missy. Or, if you’d prefer, Random Access Neural Integrator. Rani for short.”
 * Even with series 8 running for one episode shorter than normal, this episode still mananges to continue the trend of the Cybermen appearing in the penultimate episode of every series since Steven Moffat assumed the role of head writer and executive producer. The Pandorica Opens in series 5, Closing Time in series 6 and Nightmare in Silver in series 7, all of them featuring the Cybermen, were also all the twelfth episodes of thirteen in their respective series.
 * From among books in which the Doctor has hidden TARDIS keys, Clara picks up a copy of The Time Traveler's Wife, which influenced the character of River Song and the plot of The Girl in the Fireplace.
 * The plot point of the dead been conscious was controversial enough for the BBC to release a statement defending it after receiving complaints from viewers.

Production errors

 * When Danny is walking across the park, his phone rings, which means that Clara is calling him. When Clara is shown holding her phone, it displays "Danny calling" which would normally indicate that Danny has called her. Furthermore, her phone clearly still shows the "Danny calling" message even when she is talking to him.
 * In addition, all smartphone-style mobile phones are designed to blank their screens when held up to a person's ear (to avoid accidental key presses by the cheek, earlobe, etc.), yet the screen on Clara's phone remains active throughout the call.

Continuity

 * In Clara's flat, there are numerous post-it notes with references to Clara's travels with the Doctor, including:
 * The Paternoster Gang (TV: The Crimson Horror, The Name of the Doctor, Deep Breath)
 * The "Impossible Girl" (TV: The Name of the Doctor, Deep Breath)
 * "Dinosaur in London" and Half-Face Man (TV: Deep Breath)
 * "Miniature Clara"" (TV: Into the Dalek)
 * Robin Hood (TV: Robot of Sherwood)
 * The Bank of Karabraxos, Psi and Saibra (TV: Time Heist)
 * Courtney Woods becoming the president and the text "Kill the Moon" (TV: Kill the Moon)
 * The Orient Express (TV: Mummy on the Orient Express)
 * In addition there were many post-it notes about Clara telling the truth to Danny. (TV: In the Forest of the Night) There is also a post-it with the words "3 months", the context of which has yet to be explained.
 * Among the post-it notes in the shelf, there is a "body swap" ticket. The Eleventh Doctor and Clara previously used one of these to infiltrate the Royal Albert Hall. (Doctor Who at the Proms)
 * The Doctor takes a call from Clara using the TARDIS's exterior phone. (TV: The Bells of Saint John, The Time of the Doctor)
 * The emergence of the Cybermen from their tombs bears similarities to their awakening on Telos (TV: The Tomb of the Cybermen) and their descending the steps of St Paul's mirrors their earlier invasion of Earth. (TV: The Invasion)
 * A female incarnation of the Master was previously mentioned to be among his various incarnations who were captured by the Sild. (PROSE: Harvest of Time)
 * The Doctor previously knew of at least one other Time Lord who changed gender, the Corsair (TV: The Doctor's Wife). The Doctor momentarily thought himself a female upon regeneration due to his long hair (TV: The End of Time), and was offered an artificially induced female regeneration at the end of his eighth incarnation. (TV: The Night of the Doctor)
 * The Doctor uses the TARDIS's telepathic interface to help them find Danny. (TV: Listen)
 * Clara attempts to force the Doctor to go back in time and avert Danny's death. This isn't the first time he has been asked to do so. (TV: Earthshock)
 * The Master previously had an assistant named Chang Lee whom he also killed, although in that case Lee was resurrected. (TV: Doctor Who)
 * The dark water shows the human skeletons inside the Cybermen. The Cyberman guarding the Pandorica under Stonehenge revealed a human skull inside its head when it attacked Amy Pond. (TV: The Pandorica Opens)
 * The windows on the door to Dr. Chang's office and the logo of 3W itself somewhat resemble the Cybus Industries logo. (TV: Rise of the Cybermen, Age of Steel) When two doors with the logo are placed next to each other, they resemble Cyberman eyes.
 * Cybermen have converted and housed the deceased before. (AUDIO: The Reaping, TV: The Pandorica Opens, PROSE: Plague of the Cybermen)
 * There is a black and white photo on Clara's bookshelf of her and her father. (TV: The Rings of Akhaten)
 * The Nethersphere is a "Matrix data slice" related to the Time Lord consciousness storage and virtual reality technology. (TV: The Deadly Assassin et.al.)
 * The St. Paul's Cathedral was made bigger on the inside by, who used it to store 91 Cybermen. This was later pointed out by the Doctor. (TV: Death in Heaven)
 * After Missy's kiss with the Doctor, he says that she is very realistic. Clara points out the tongue, prompting a "shut up" from the Doctor. The Tenth Doctor had previously told the Eleventh Doctor to shut up when he pointed out the earlier incarnation had kissed a Zygon. (TV: The Day of the Doctor)
 * The Master previously worked briefly with the Cybermen before, albeit only because he was forced to at that time. He soon tricked that group of Cybermen into their demise. (TV: The Five Doctors)
 * We finally learn what Danny's "bad day" was that forced him out of the army. (TV: Kill the Moon)
