# Doctor Who series 9

The ninth series of the British science fiction television programme Doctor Who premiered on 19 September 2015 with "The Magician's Apprentice" and concluded on 5 December 2015 with "Hell Bent". The series was led by head writer and executive producer Steven Moffat, alongside executive producer Brian Minchin. Nikki Wilson, Peter Bennett, and Derek Ritchie served as producers. The series is the ninth to air following the programme's revival in 2005, and is the thirty-fifth season overall.
This is the second series starring Peter Capaldi as the Twelfth Doctor, an alien Time Lord who travels through time and space in his TARDIS, which is disguised as a British police box. It also stars Jenna Coleman as the Doctor's companion, Clara Oswald, for her third and final series in the role. Also playing a major recurring role in the series is Maisie Williams as Ashildr, a Viking girl made immortal by the Doctor, which leads to major events resulting from her encounters with the Doctor. The series' main story arc revolves around the mystery of a being called the Hybrid, the combination of two great warrior races. The Doctor's investigation into this being ultimately leads him back to his home planet of Gallifrey, which returns fully in the series.
Steven Moffat wrote four episodes solo and co-wrote an additional two. The other writers who worked on this series included Toby Whithouse, Jamie Mathieson, Catherine Tregenna, Peter Harness, Mark Gatiss, and Sarah Dollard. The ninth series received acclaim from critics, with many labelling it as the show's strongest season to date. Aspects of the series that were met with the most praise included the writing, directing, and structure of the series, as well as the performances of Peter Capaldi, Jenna Coleman and Maisie Williams.

| The Doctor attempts to rescue a boy on a battlefield, but upon discovering that the boy is a young Davros, abandons him and goes missing. On Earth, Clara is summoned by UNIT when all of the world's aircraft freeze in the sky, and they discover Missy is causing the phenomenon. Missy has the last will and testament of the Doctor, called his confession dial, and tells Clara that they must search for him. They trace him to Essex in 1138, where he has spent three weeks throwing a party. When Clara and Missy reunite with the Doctor, an agent of Davros called Colony Sarff arrives and explains that the elderly Davros wishes to see the Doctor, before taking the three to a hospital space station. Clara and Missy discover the station is a building on an invisible planet, but as the landscape reappears, Missy identifies the planet as Skaro, the home planet of the Daleks. They are captured by the Daleks, who appear to kill them and destroy the TARDIS. The Doctor returns to the battlefield, holding a Dalek weapon, preparing to save his friend. ||||||||

| Using Dalek energy, Missy was able to power her teleporter for her and Clara to escape. The two attempt to find the Doctor, going through the sewers, which are filled with decaying Daleks. They successfully kill a Dalek and empty its case to disguise Clara inside of it. Meanwhile, the Doctor comforts the dying Davros, feeling compassion for him having abandoned him as a boy in the past. The Doctor uses a little regeneration energy to power Davros' life support, which is also connected to every Dalek. This turns out to be a trap, and begins draining the Doctor to regenerate Davros and the Daleks. Missy saves the Doctor, and the energy also restores the dying Daleks, who wish to destroy the functional Daleks. While escaping, the Doctor and Missy encounter Clara's Dalek. Missy tries to trick the Doctor into killing her, but fails after the Dalek asks for mercy. Missy escapes. Using his new sonic sunglasses, the Doctor summons the TARDIS, which also had avoided destruction by its automated systems. The Doctor then returns to the battlefield, where he does not kill Davros, but destroys the mines to free him, and then helps him home. ||||||||
| 255a | 3 | "Under the Lake" | Daniel O'Hara | Toby Whithouse | 3 October 2015 (2015-10-3) | 5.63 | 84 |
| The Doctor and Clara arrive in an underwater base in 2119. The military team there have discovered an alien craft in the ruins of a submerged Scottish town with glyphs scratched in its inside walls, but Commander Moran was killed upon its discovery. At night, the ghosts of Moran and a Tivolian appear. The Doctor and the others attempt to capture the ghosts and understand what they want, and find out that they are repeating coordinates. They find an unopenable stasis chamber at the church where the coordinates led. The Doctor concludes that the ghosts are being used to send a call to the location. The Doctor decides to go back to before the flood and find out the true meaning behind the signal. Clara, acting commander Cass, and crewmember Lunn are separated from the Doctor and crewmembers O'Donnell and Bennett. Shortly after the Doctor, O'Donnell, and Bennett leave in the TARDIS, Clara spots a new ghost in the lake, only to discover that it is the Doctor. ||||||||
| 255b | 4 | "Before the Flood" | Daniel O'Hara | Toby Whithouse | 10 October 2015 (2015-10-10) | 6.05 | 83 |
| The Doctor, Bennett, and O'Donnell land in 1980. They discover that the Tivolian, Prentis, is still alive, the writing has not yet been scratched into the wall, and Prentis landed on Earth to bury his former enslaver the Fisher King. The Doctor contacts Clara in 2119, who tells him the Doctor's ghost is mouthing their names. The ghost releases the others from the Faraday cage. In 1980, the Fisher King awakes, killing Prentis and writing the glyphs on the wall. O'Donnell is killed, confirming the suspicion that the Doctor's ghost is saying the order in which they will die. Attempting to save Clara, the Doctor confronts the Fisher King. He tells the Doctor the ghosts created by the glyphs will send a signal that will draw an armada. The Fisher King is drawn away from the chamber, and the Doctor destroys the dam wall, flooding the town. The stasis chamber opens in 2119 to reveal the Doctor inside; his "ghost" is a hologram, programmed by the Doctor. The hologram lures the ghosts back inside the Faraday cage. The plot is a bootstrap paradox—the Doctor programmed the ghost to say the names because that is what the ghost's message said. ||||||||

The next day, the Mire invade, and the Doctor steals a helmet for Ashildr to use. She broadcasts a vision of a dragon into the Mire's other helmets and forces them to retreat, but she dies from the use of her helmet. The Doctor and Clara mourn, but then the Doctor realises his face is a reminder that he does not have to follow the rules of time and space. He uses a Mire medical chip to bring Ashildr back to life. This makes her immortal. He provides the second chip in hope she would give it to one she cares for. ||||||||

Throughout her immortal life, she has lost many memories, and now isolates herself as to not lose loved ones. Me and the Doctor steal the artefact from Lucie's house. The Doctor meets Me's ally Leandro, a leonine alien stranded on Earth who uses the artefact to open portals into space. In return for Me tricking the Doctor into helping him, Leandro has agreed to let her come with him to travel the galaxy. However, in order for the portal to be activated, the artefact requires another person's death. Me kills the outlaw Sam Swift, opening the portal. Leandro reveals that his intent is to assist his people in invading Earth. When Me rediscovers her humanity after seeing spaceships attack the crowd, she uses the medical chip to save Swift, closing the portal. Leandro's people kill him for his failure. Afterwards, Me says that she will look after those that the Doctor leaves behind. ||||||||

The Doctor leaves the Osgoods the Osgood Box to be used as a last resort. In New Mexico, a Zygon splinter group kidnaps Osgood. In London, a splinter group member called Bonnie takes over Zygon High Command. At the block of flats where Clara lives, Clara is knocked unconscious and hidden in a pod underground. Bonnie takes Clara's place. Bonnie tricks UNIT troops into going to a series of underground tunnels, which many other lifts across the city are connected to. The troops are killed by the splinter group when they attempt to escape. Kate Stewart is attacked by a splinter group member disguised as a sheriff while investigating Osgood in New Mexico.

| The Doctor and Osgood escape the plane before it is shot down. Within Clara's mind, Bonnie learns that the Osgood Box is held in UNIT's Black Archive. Against the wishes of the Zygons who are not aligned with the splinter group, Bonnie intends to start a war against humanity by using the Osgood Box to unmask 20 million Zygons on Earth. Clara telepathically breaks through Bonnie's control and alerts the Doctor to her whereabouts. Kate, having survived the encounter in New Mexico, joins the Doctor and Osgood. The three arrive at the Black Archive where Bonnie has found there are two Osgood Boxes, one which would either unmask the Zygons or make their human forms permanent, and the other which would destroy either every Zygon or everyone in London. When Bonnie and Kate prepare to activate the boxes, the Doctor talks them out by explaining the Boxes are a means to assure peace because of the consequences of declaring a war. Bonnie realises the boxes are empty as a ploy. The Doctor wipes Kate's memories to keep the peace treaty. Bonnie calls off the splinter group and says they will live peacefully. Bonnie becomes the new Osgood duplicate. ||||||||

| A four-person rescue team from Triton arrives at Le Verrier Lab, a space station in the 38th century in orbit around Neptune which has fallen silent. They meet the Doctor and Clara, who claim to be assessors. They then meet Gagan Rassmussen, the last survivor of Le Verrier and creator of large pods called Morpheus, which reduces the time a person sleeps to allow them to work more but also mutates the rheum in the corner of the eye into a carnivorous life form called the Sandmen. Chopra, Deep-Ando, and 474 are killed during their escape. Rassmussen plans to use the rescue ship to return to Triton and release Morpheus there with a Sandman, which he says is now spread by spores. The Doctor destroys the gravity shields, sending the station and ship into Neptune. The Doctor comments that the inconsistencies in how Morpheus is spread seems to be contrived like a story. The Doctor, Clara, and Nagata escape in the TARDIS. Rassmussen, revealed to be a Sandman himself, orchestrated the events to use footage collated from people's vision to create a video that people would watch to transmit the Morpheus signal across the Solar System to create more Sandmen. ||||||||

After examining him, they trace his movements to a trap street in present-day London that houses extraterrestrial refugees. They then discover Rigsy was sentenced to death by Me, the street's mayor, for murdering an alien called Anah and that Rigsy will be killed by an alien raven when the tattoo, known as a Chronolock, reaches zero. Clara discovers that the Chronolock can be transferred to a willing recipient and takes it from Rigsy, believing that Me will spare her, buying them more time. The Doctor realises from the medical data in the stasis pod Anah is stored inside that Anah is still alive; Me made a deal with an unknown party to have the Doctor transported far away to keep the street safe. As the Chronolock has been passed on to Clara, Me cannot remove it and Clara cannot be saved. Clara pleads with the Doctor not to take revenge for her. The raven kills Clara, and the Doctor is teleported away. ||||||||
| 261 | 11 | "Heaven Sent" | Rachel Talalay | Steven Moffat | 28 November 2015 (2015-11-28) | 6.19 | 80 |
| The Doctor teleports into a chamber in a castle. He is followed by a creature which intends to torture him, but discovers that after giving a confession of some kind, the creature will temporarily retreat and the castle will shift its form. The Doctor seeks to escape, and investigates clues that direct him to a particular room, in which he finds a wall made of Azbantium, a mineral harder than diamond. He determines that he has already been in the castle for 7000 years. Understanding what this and other clues imply, he tries in vain to break the wall with his fist, but the creature appears and mortally wounds him. He crawls back to the room he appeared in, and sacrifices himself just as the configuration of the castle resets, rematerializing a copy of himself exactly as he originally teleported in. By exactly repeating this entire cycle of events innumerable times, the Azbantium wall is eventually weakened and he breaks through. Stepping through the breach, the Doctor sees he was inside his confession dial all along, and is now on Gallifrey, eons from now. He tells a nearby child to go to the city and inform the Time Lords he is on his way and that he knows what they did. ||||||||

| Aided by the Gallifreyan military, the Doctor usurps and exiles Lord President Rassilon. Now the new President, the Doctor learns that Rassilon imprisoned him in the dial to force him to confess about the Hybrid, which is prophesied by the Time Lords to stand in Gallifrey's ruins and unravel the Web of Time. The Doctor has the Time Lords retrieve Clara from her timeline at the instant of her death, ostensibly so the Doctor can consult her about the Hybrid. The Doctor escapes Gallifrey with Clara with a TARDIS stolen from the workshops under the Capitol, attempting to take her far away enough that she will return to life, despite this potentially damaging time. At the end of the universe, the Doctor encounters Ashildr in Gallifrey's ruins; the two conclude the Hybrid is the Doctor and Clara together. The Doctor decides to remove Clara's memories of him to prevent the Time Lords from finding her, but Clara alters the device so it will affect the Doctor. The Doctor wakes in the Nevada desert where his own TARDIS has been moved. Clara, travelling with Ashildr, begins her trip to Gallifrey in the TARDIS stolen from Gallifrey to return to her death. ||||||||

Surprised that River cannot identify his newest face, the Doctor struggles to break the news to her while learning how she acts on her own – and how many other lovers she has had. The Doctor and River bring the head of Hydroflax to the starship Harmony and Redemption to sell it, and a series of events causes River to discover the Doctor's identity. The starship is caught in a meteor strike and crashes into the planet Darillium, where the Doctor and River are fated to have their final date together before River dies meeting a younger Doctor. Having deliberately held it off for as long as possible, the Doctor finally decides to give in and arranges for a restaurant to be constructed on the planet. The Doctor and River then have their final date together, which lasts for 24 years – the span of a night on Darillium. ||||||||

## Production
### Development

Before series 8 began, Moffat promised a cliffhanger for series 9, and teased in Doctor Who Magazine Issue 475, "I've figured out the cliffhanger to the penultimate episode of series 9. And it's a whopper. Ohh, I don’t think you'll see this coming!" The series saw the return of the cliffhanger, with six of the twelve episodes divided into two-parters. Moffat has stated that the two-part stories are not as connected as similar stories in previous series, but instead are quite different and only vaguely related. In April 2015, Steven Moffat confirmed that Doctor Who would run for at least another five years, extending the show until at least 2020.
As the series coincides with the 10th anniversary of the show's revival, the BBC asked former showrunner and head writer Russell T. Davies to return, but he declined. A BBC source said that plans for the revival anniversary were still to be decided, despite Davies' reluctance to return. He also believed that the success of the revived show meant that "It’s now impossible for it to ever be axed." However, despite the comments made to Radio Times, in an interview with BBC Radio 2 a week later, Davies said he would love to write more Doctor Who, specifically a movie.

### Writing

Steven Moffat wrote the opening two-parter story, and Catherine Tregenna wrote an episode for the series. Tregenna had previously been involved in Doctor Who spin-off series Torchwood.
In January 2015, the Doctor Who Twitter page reported that filming had begun on episodes written by Toby Whithouse, who had previously contributed episodes "School Reunion", "The Vampires of Venice", "The God Complex" and "A Town Called Mercy". On 16 March 2015, Mark Gatiss confirmed he would be writing an episode for the series. On 30 March 2015, it was confirmed Jamie Mathieson, who previously wrote "Mummy on the Orient Express" and "Flatline" for series 8, would write a new episode called "The Girl Who Died" with Moffat. On 8 May 2015 it was announced that Peter Harness, who wrote series 8's "Kill the Moon", would write a two-part story. Justin Molotnikov was to direct two 60 minute episodes for Doctor Who, according to his CV, though this was removed at a later date. However, he directed the ninth and tenth episodes of the series.

### Music

Murray Gold composed the soundtrack to this series, with orchestration by Ben Foster.

### Filming

Filming and principal photography for the ninth series began on 5 January 2015 in Cardiff, with "Under the Lake" and "Before the Flood" making up the first production block. The read-through for the first block took place on 18 December 2014. The second production block consisted of two of Steven Moffat's episodes, the opening two-parter. Filming for the story took place in Tenerife, Spain, in February 2015, directed by Hettie MacDonald, who directed the 2007 episode "Blink".
On 30 March 2015, it was announced that Ed Bazalgette would direct two episodes, one written by Jamie Mathieson and Steven Moffat and the other by Catherine Tregenna. On 8 May 2015, the BBC announced that filming had started on a two-part episode written by Peter Harness and directed by Daniel Nettheim. On 10 June 2015, it was revealed by the BBC that filming for Block 5 had begun with Justin Molotnikov directing "Face the Raven", written by Sarah Dollard. On 1 July 2015, the BBC confirmed that Rachel Talalay would return to direct the final two episodes of the series, both written by Steven Moffat.

### Critical reception

Doctor Who's ninth series received positive reviews, and was hailed by some critics as one of the show's best seasons to date. Series 9 holds a 90% approval rating on online review aggregate site Rotten Tomatoes with an average score of 8.25/10. The site's consensus reads "Peter Capaldi and the writers have settled into an emotionally engaging tone, allowing the show to raise the stakes for the Twelfth Doctor". Reaction to individual episodes has also been highly positive, with scores on the site ranging from 61% to 95%. Episodes such as "The Woman Who Lived" and "Heaven Sent" received particular acclaim, with critics saying that the former "should be an episode that goes down in Doctor Who history" and "stands as perhaps the strongest entry of Season Thirty-Five thus far", whilst the latter was labelled "a masterpiece of the highest order" and "an instant classic". The lowest-scored episode for the season was the episode written by Mark Gatiss, "Sleep No More", which gained a 61% rating.
In reviews for various episodes across the series, some critics highlighted series 9 as the show's greatest yet. In their review for "Hell Bent", IGN called series 9 "a very strong season of Doctor Who – possibly the best season of the modern run of the show", while New York Magazine stated "It’s been a largely brilliant season... possibly even the best since the new series began" in their review for the same episode. Discussing the series as a whole, The A.V. Club stated "Doctor Who is great again, and this season represents maybe the best mixture yet of the show’s head and its heart". Of the twelve episodes in the season, they awarded five a perfect 'A' grade (the most for any season of the show), while awarding a further five episodes either an A− or a B+. Furthermore, TVEquals.com called series 9 "one of the strongest seasons of the show in years".
