The Zygon Inversion (TV story)

 was the eighth episode of the ninth series of Doctor Who produced by BBC Wales.

This episode saw the Twelfth Doctor describe the immense pain he felt while fighting in the Time War in an emotional and angry speech for the first time since his predecessor discovered that the War Doctor had not destroyed Gallifrey in The Day of the Doctor. It also revealed that there are two Osgood Boxes, and their design is based on that of the Moment; this symbolises how the Doctor nearly destroyed his entire race with a box in The Day of the Doctor, just as Kate and Bonnie were about to destroy theirs. It did not elaborate if the human Osgood or Zygon double was still alive, instead having Bonnie fill the vacancy in the form of a replacement double for the one of the two who had been killed by in Death in Heaven. Osgood explains that she can be either version; Zygons don't need the person that they copy if their memories are unneeded. In a behind the scenes extra, Ingrid Oliver, who played Osgood, has chosen which of the original Osgood duo is left; she keeps which one she picked a secret.

It also saw a new way of Zygon-transformation for the first time, showing the immense pain of a lengthy forced transformation from human-form into Zygon-form. It also shows Zygons can now read the minds of their enemies and take the form of their loved ones; using this method, they can disarm their enemies and leave them vulnerable.

Synopsis
With the splinter group of Zygons now ahead of the Doctor, there is only one thing standing in their way of obliterating the human race and taking the Earth for themselves: a moral dilemma!

Is Bonnie willing to compromise the peace already in place, just for the sake of Zygons not needing to hide, even if it means making enemies not only of humanity, but of her own race?

Plot
Clara awakens in her apartment, deciding to get ready for the day; however, when she tries to brush her teeth, she finds black gunk coming out of the toothpaste tube. Tossing it aside, Clara soon hears Bonnie's voice taunting the Doctor, finding her living room television filled with static. She quickly checks a magazine, finding it filled with gibberish; she's dreaming. Running through her apartment, Clara finds the doors locked and the windows missing. Clara tries tuning in a channel, finding herself seeing what Bonnie does; she's targeting Boat One with a rocket launcher.

Realizing the Doctor is in danger, Clara knocks her television over. This causes Bonnie's arms to fly to her left, firing the a rocket off-target. Bonnie passes this off as a spasm, loading another rocket. Clara tries moving the television again, but finds it stuck; she forces her hand to gain control over Bonnie's trigger finger, holding off the shot as long as she can. Finding herself losing, Clara bites her finger, hoping to stop Bonnie; however, the Zygon gets her shot off and blows up Boat One successfully this time.

Later, members of Truth or Consequences have murdered more humans in London. Having returned to human form, most lounge while another sweeps up the remains. The area has been covered in graffiti of their symbol. A man, Etoine, is shown running with his shopping bags; tripping, he leaves them and continues running into his flat. Walking calmly behind him is none other than Bonnie.

Etoine gets to his home and locks the door, running into his living room. Hearing a loud knocking, and then a crash, Etoine shivers in fear. Bonnie surprises him, having broken down his door. Telling Etoine she knows he is a Zygon, Bonnie tells him that the humans will never accept them; he will be the first to make them see them for who they are. Despite his pleas to leave him alone, Bonnie zaps his head, prompting Etoine to flee. She follows with a dark smile on her face. Outside, Etoine asks his fellow Zygons to help him, as his disguise starts to fail. Changing, back completely, Etoine flees into the nearby market. Bonnie records his transformation and posts it on the internet to spread panic and paranoia among the humans.

At the same time, Clara reviews the destruction of Boat One. Pausing Bonnie's memory of it, she sees two parachutes escaping the blast and smiles.

On a beach, Osgood frees herself from her chute and notices her glasses are broken. The Doctor asks her if she has any question, to which she asks about the Union Jack on his chute; he responds that it's camoufluge for being in Brittan. He offers Osgood his sonic sunglasses in the meantime, telling her not to look at his user history; she finds the idea of sonic eye-wear silly. She then catches him talking nonsense to distract her, one of his best known traits. Osgood then tells him that Bonnie made the mistake of giving him a chance; if she wanted to takeover Earth, she would kill him outright with a bullet between the eyes for each regeneration and not let him talk. The Doctor notes how oddly prepared Osgood is for that scenario; she tells him it's because she's such a big fan.

As the Doctor and Osgood trek on, she notes that it's rather odd that Bonnie didn't blow them up with her big bazooka. However, the Doctor retorts "this is us blown up by a big bazooka". Osgood explains that if Bonnie had Clara's memories, she would know better than to give him a chance as that will come back to haunt her. Realizing the Doctor has gone silent because she's mentioned Clara, Osgood asks how he's feeling; the Doctor says he's still in his "hope phase". When Osgood asks him how that is, he tells her it's Hell and to change the subject.

Elsewhere, Bonnie is walking through the streets. Unknown to her, Clara uses their link to manipulate her right hand; Clara is using her phone to text. The Doctor gets the text, which says "I'm awake.' Wondering if it means a political awakening, he becomes confused as to why the Zygon is sending him propaganda if it thinks it blew him up. However, Osgood tells him that it came from Clara, telling the Doctor that she's fighting back. She asks how his hope phase is, to which the Doctor says is worse than ever. Smiling, Osgood tells him that they have a game now.

Bonnie enters the UNIT base and opens a safe behind the portrait of the Doctor's original incarnation. She finds a laptop inside and turns it on. A message from the two Osgoods plays, explaining that if they were captured and interrogated, they gave up the location of this laptop. However, the Osgood Box is not there; they firmly explain that it's the truth and further looking would be a waste of time. They smile, asking the watcher if they've figured out why it's called an Osgood Box. Seething with anger, Bonnie snarls and tosses the laptop to the ground, stomping on the worthless device until it's in small pieces.

Back on the beach, the Doctor and Osgood see a police car. Racing up to it, the Doctor passes himself off as "Dr John Disco", telling the officers that his plane blew up, but there's nothing to worry about. However, the officers don't appear that surprised by what he's telling them. Worrying that they may be Zygons from the splinter group Truth or Consequences, the Doctor and Osgood begin walking away. However, another pair of officers begin approaching from where they came from.

Osgood video calls Clara's phone, surprising Bonnie that they're still alive. Taking the phone, the Doctor asks what the plan is, only for Bonnie to say she doesn't have one; he tells "you don't invade a planet without a plan; that's why they're called planets, to remind you to plan it." Bonnie asks him where the Osgood box is, winking due to Clara trying to signal the Doctor. Thinking the Zygon is flirting with him, he states "I'm old enough to be your messiah".

However, Bonnie insists that she isn't winking; realizing it's Clara, the Doctor tells Osgood to use the sonic sunglasses to break into a nearby van. As Clara wouldn't know morse code, the Doctor learns from her winks (which stand for "yes") that her pod is in London; he then tells Clara not to let the Zygon know what's in her mind. Boarding the van, he is told by Osgood that obviously Bonnie heard that; he smiles, knowing that - "The mind of Clara Oswald; she'll never find her way out."

At the Zygon nest, Bonnie approaches the pod holding Clara and telepathically talks to her; Bonnie appears on the TV screen in Clara's dream. Clara uses the link to force Bonnie back to Zygon form briefly. However, upon saying she's a great liar, Clara is shocked by the news that Bonnie shares her pulse and will be monitoring it to make sure she's telling the truth. Bonnie interrogates her, learning that the Osgood Box is at the Black Archive under the Tower of London, and that Clara does has access. Bonnie is then surprised to learn Clara can't give her the access, because she already has it; she has Clara's boydprint, so she automatically has access. However, Clara taunts Bonnie, saying that even though she's given this information, the Zygon will still need her. "Kate" arrives, explaining that the Doctor is on his way; Bonnie orders that he be copied, if possible, but disposed.

Seeing the video Bonnie posted on the Internet, the Doctor and Osgood head to find the Zygon she attacked in the south London shopping centre the Fleet Estate Centre. They find several piles of dead people. The Doctor asks Osgood for her first name, but she asks for his; going with "Basil", the Doctor learns her full name is Petronella Osgood. Not liking it, he tells her they should stick to what they had. They see Etonie and run after him. Cornered, Etoine explains he was just defending himself. Having trouble keeping his human form due to the zap Bonnie gave him, he says he didn't want to be a part of their war.

The Doctor and Osgood try calming him and offering help; however, he thinks they may be more of Bonnie's stooges. Not wanting to live under the rule of Truth or Consequences, Etoine kills himself out of fear. Kate arrives with two guards, telling the Doctor and Osgood that she knows where the nest is; it's also where Clara's pod is. The Doctor is elated by the news, telling Kate to lead the way. At the Black Archive, Bonnie is amused she got waved through due to looking like Clara; Clara's pod is wheeled in by her guards. At the Zygon nest, Kate attempts to show the Doctor where Clara's pod was. However, the Doctor then realizes that he just walked into a trap. Bonnie calls to gloat, but soon finds out why the device is called the "Osgood" Box - there's two of them. Bonnie has Clara awakened, but learns she doesn't know which of the boxes is the right one; Clara points out that Bonnie should have already known this because their minds are linked.

With Clara threatened, the Doctor is forced to tell Bonnie that the red one will revert the Zygons to normal, while the blue one kills them. However, much to Bonnie increasing anger, there are two buttons in both boxes, and the each say Truth and Consequences. "Operation Double, two Osgoods; what did you expect?" the Doctor laughs. He refuses to tell which button does which, making Bonnie order his exectution. However, Kate shoots the Zygons instead. A surprised Doctor asks who she is, to which Kate says "I'm me". When the Zygon attacked her back in New Mexico, Kate emptied her gun into it and took its place to get close to Bonnie.

Angered, Bonnie is left to wonder which box to use. Clara tells her that she can't win; however, Bonnie voices the fact that she doesn't care. The Doctor, Osgood and Kate arrive, with the Doctor asking to be let to take the boxes away; without them, they can forgive and forget what has happened here. However, Bonnie is defensive, believing that she won't be forgiven for all the deaths she caused.

Kate goes over to the red box, ready to use it to defend the human race, while Bonnie goes to the blue one, ready to liberate the Zygons. The Doctor tells them that Bonnie's box will either cause the Zygons to revert to their true forms for an hour or cancels their ability to change form, thus making them human for good; Kate's box will either release "imbecile's gas" (a gas poisonous to Zygons created by Harry Sullivan) into the atmosphere or detonate the nuclear warhead beneath the Black Archive, destroying London. "There are safeguards beyond safeguards. I did this on a very important day for me. This ceasefire WILL stand."

The Doctor asks Bonnie what it actually is that she wants, to which she answers: war. He then asks her to paint a picture of what the future will be like; will there be music, jobs, etc? As she can't give an answer, the Doctor scolds her, telling Bonnie that she's like every other tantruming child; she doesn't actually know what she wants. He further asks what will Bonnie do once everything is right and just, with all "the bad guys" gone, what will protect her "glorious revolution" from the next, because there will still be rebels in any species. When Bonnie says that they will continue to win, the Doctor says that they might, but NOBODY wins for long.

With both Kate and Bonnie willing to press their buttons on the gamble of a 50-50 chance, the Doctor can't resist making fun of the situation like a game show announcer; he then snaps at them, saying this is a scale model of war. The Doctor continues, saying no matter how right you feel at the beginning, you don't know who's going to die, whose families are going to be torn apart, who's lives are ruined forever. This situation is what it always boils down to: "Sit down and talk!" Bonnie accuses the Doctor of setting up the entire problem. They then get in a fight over what's fair, to which the Doctor points out is part of life. Bonnie still refuses to stand down, claiming that she will be punished for her revolution. The Doctor chides her, comparing her to a child thinking that they're unforgivable, yet he tells her that despite her atrocities that he forgives her.

When Bonnie says the Doctor could never understand her situation, the Doctor is incredulous, he tells her that this little squabble isn't a war; he fought in a bigger war than she will ever know. Growing more angry and traumatised as he remembers, the Doctor tells her that he did more horrible things that she can imagine and when he closes his eyes, he can still hear the countless screaming of the victims. Clara closes her eyes in response, having seen the Time War herself and knowing of the true horror the Doctor's seen. He tells Bonnie that what you do with this pain is to hold it tight until it burns your hands, and say: "No-one else will ever have to live like this. No-one else will ever have to feel this pain." Bonnie is swayed by the Doctor's words, telling him she's figured out the boxes are empty; the Doctor says that she only knows this because she's started to think like him - "it's hell, isn't it.". However, Kate is less than amused; they know the boxes are empty now, so this can't work twice. Telling Kate that she's already scolded him 15 times, the Doctor again wipes her memory with the device in the ceiling; Bonnie's guards also had the memories wiped. Bonnie wondered how the Doctor was able to know she would side with him; he tells her it's because Clara got into her head, just like him. She helped him on the day he planned to use the Moment; Clara made him see a better way. Bonnie looks at Clara with a smile. The Doctor smiles at Bonnie, telling her that once Clara gets in your head, "she never leaves."

Bonnie returns to her nest, telling her comrades the revolution is over and that they're safe. Outside the nest, the Doctor asks Osgood to travel with him; however, she turns him down, saying that she needs to be around to make the Nightmare Scenario work out like this again. Per the Doctor's request, Clara hugs Osgood on his behalf. However, the Doctor is left bewildered that Osgood never thought of what the TARDIS stood for; he tells her it stands for "Totally And Radically Driving In Space". Clara boards the TARDIS, waiting for the Doctor to take her on another adventure.

The Doctor tells Osgood that he needs to know which she is: human or Zygon? Osgood smiles, telling him that she will answer that one day. To the Doctor's shock, another Osgood walks up, telling him that the day will be when the answer doesn't matter. The two of them explain that it wouldn't be OK to use Clara's face when there's a vacancy for an Osgood. Both of them say that it doesn't matter which is Osgood and which is Bonnie, only that Osgood lives. The Doctor tells them that they are a credit to their species. Both Osgoods reply that they're a credit to both species. Smiling, he tells them he's a fan of their work.

Back in the TARDIS, Clara asks the Doctor if he thought she was dead for a while. Solemnly, the Doctor states "Longest month of my life". Clara laughs, saying it could have only been for a few minutes. Pulling a lever, the Doctor tells Clara to let him be the judge of time.

After the TARDIS departs, both Osgoods decide to get ice cream before heading back to work.
