Osgood sits up, still wearing the parachute harness. She feels around her for her spectacles and finds they have broken at the bridge. "Doctor?" She called as she took off her harness. "Claudia?"

"Here!" Claudia shouted, waving her hand. She already took out her harness as the Doctor looked around, scanning the area with his sonic sunglasses.

"Any questions?" He suddenly asked Osgood.

"Why do you have a Union Jack parachute?"

"Er, camouflage."

"Camouflage?"

"He just wants to show off," Claudia huffed, trying to see if there were any enemies nearby. It would be bad if those Zygons rebels know about their whereabouts.

"Oh, your specs are broken. I'll fix them," the Doctor noticed and took Osgood's glasses while giving him his. "You can wear mine, they're sonic."

"Sonic specs?"

"Don't even know where he got the idea," Claudia added as they started walking.

"Isn't that a bit pointless? Like a visual hearing aid?" Osgood frowns.

"What's wrong with pointless?" The Doctor raises his eyebrow. "I once invented an invisible watch for Sunny. Which, I supposed, isn't exactly a good birthday gift."

"You're talking nonsense to distract me from being really scared. It's one of your known character traits," she recalled and puts the sonic sunglasses on.

"Actually, let me adjust it," Claudia suggested, using her sonic pen for Osgood to wear before they reach the concrete jetty leading up off the beach and walk up it.

"Ah. Much better. Why didn't that Zygon blow us up with her big bazooka?"

"She did blow us up with her big bazooka. This is us being blown up with a big bazooka," the Doctor clarified.

"But, I mean, she seems to know what she's doing. The first thing I'd do if I wanted to invade the world would be to kill you or your companions."

"She definitely wants to taunt us, to make us feel hopeless," Claudia denoted. "Biggest mistake to make."

"But she gave us a chance to get out. She hesitated. If she had Clara's memory print, she'd know better than to give you or the Doctor even a second."

"Which means, something intervened her. Or I guess… someone intervened."

"You're suggesting that Clara is still alive?" Osgood realised as they reached the access road.

"Her jumping to the Doctor's timestream didn't just create echoes of her. She's also making herself connected to me. I can sense her life energy. And if she dies, then I will sense it too," the bluenette explained, touching her chest where she can sense her heartbeats.

Osgood nods, trying to process that fact. "Then, why do they want to destroy the ceasefire?"

"Don't think of them as rational. They're different. They don't care about human beings, they don't care about their own people. They think the rest of Zygonkind are traitors," the Doctor remarked before his phone bingles. "It's a splinter group."

He takes it out of his pocket and looks. The sender is Clara. Claudia quickly opens the message.

I'm awake.

"She's fighting back. She's trying to take control, piece by piece," Osgood concluded.

"By texting," Claudia amused.

"The Zygon probably doesn't even know it sent this, or why it misfired that bazooka."

"And let's just hope she doesn't know."

▪︎▪︎▪︎

Arthur winces his eyes as he finds himself standing on a road. There's nobody around, which is weird itself. There's no car either.

Oh, scratch that. There's a police car.

"Hello!" Arthur calls as he steps closer to the police car and knocks three times on the window. The policemen wind down the window, showing no expression. His partner also have the same expression. "Can you tell me where I am?"

No response. Somehow, this is just getting creepier than he usually deals with.

"Never mind," Arthur quickly said and turned back, trying not to think about those policemen taking an interest in him.

He quickly spots the Doctor, Osgood, and Claudia heading on the same route he went before. "Run!" He hissed.

"What?" The Doctor shouted before Claudia pointing something behind Arthur. When the boy looks behind, he finds the police car is trying to reverse to block access back to the beach. He makes an 'oh' face before ushering Osgood and Claudia to walk into another direction.

Claudia calls Clara back. "Hello, Bonnie," she snarled, putting it on loudspeaker

"You're dead."

"Yeah, as if that could happen. What exactly are you planning?"

"I don't have a plan."

"Come on, you don't invade planets without having kind of plan. That's why they're called planets, to remind you to plan it?" The Doctor remarked and looked at Arthur excitedly. "Hey, hey! That's good! Pun-tastic. Doctor Pun-tastic! Oh, come on, that was a good one, Zygella!"

The policemen start to get out of the car to follow them. Claudia quickly uses her sonic pen and aim it at the car in order to hit those policeman from following them.

"Don't call me Zygella. My name's Bonnie," she insisted and adding a quick wink.

"And you're winking at me."

"I am not winking at you. Where is the Osgood box?" She asked and wink.

"You do know what winking means? You're sending out some very mixed messages here. You know I'm over 2000 years old? I'm old enough to be your Messiah."

"Holy crap," Arthur muttered as more policemen approached.

"I am not winking at you. Where is the box?"

"There!" Claudia gestures to a VW van parked half on the pavement and half on double yellow lines. Claudia uses her sonic pen to open the door, letting them in. She and Arthur take the backseat, the Doctor takes the driver seat, and Osgood takes the front seat beside the Doctor.

"Okay. Non-verbal communication. I assume that you never bothered to learn Morse code," the Doctor guessed as he started the engine using his sunglasses.

"Tell me!"

"Where's your pod? Is it in a tunnel? Is it in London? Is it near your apartment?" Claudia suddenly asked her without a pause, causing Bonnie to twitch her eyelids and raise her hand to cover one then both of them. That's all she needs. "Got you!" She snarked before the Doctor started driving away.

"Stay where you are, Clara. We're coming to get you. And for God's sake, don't let her into your memories," the Doctor warned.

"Memories? What memories? What has she got?" Bonnie demanded.

Claudia quickly ends the call and hands the phone back to Osgood. "Obviously, the Zygon could hear that," Osgood remarked.

"Which is what you purposely did," Arthur pointed out.

"She's smart," Claudia said. "Even if Bonnie's going to look inside her mind and get her answer, she'll find out why we gave that hint away."

The Phone beeps. "I got a ping on Clara's phone," Osgood informed and read it. "It's the location Bonnie sent the text from. A shopping centre, south London."

"Ah, London. Perpetual city, cradle of culture, here we come!" The Doctor exclaimed. "Clara, stay safe."

"She's posted a video link."

All of them take a look at the video, showing news about a man turning into a hideous Zygon as a woman saying, "A video supposedly showing an alien in south London is posted across the internet."

"That's not good," Arthur gloomy said.

▪︎▪︎▪︎

The van screeches to a halt near a street. The Doctor, Claudia, and Arthur Osgood get out. Claudia is tracking the exact location of the text and video using her sonic pen as Osgood holds the phone, and has her own spectacles on again.

"London!" The Doctor said and spread his arms wide. "What a dump."

"It's not a dump. Stop complaining," Arthur remarked, already tired of hearing the Doctor complaining about how terrible London is for the last 30 minutes.

"It's a dump, Sunny. It's always been."

"You spend an awful lot of time here, considering it's a dump," Osgood pointed out.

"I spend an awful lot of time being kidnapped, tortured, shot at and exterminated. Doesn't mean I like it," the Doctor said.

"This should be where the video was shot," Claudia denoted as they entered the place.

"There's electricity in the air," Arthur frowns.

"It stinks. It smells like barbecues," Osgood added as they all take a few steps further in. "Oh."

"What in the—?"

"Just ignore it and keep walking."

"It's getting dark," the boy pointed out, quickly taking out three flashlights he carries. "Here."

"Thank you, dear," Osgood nods and tosses the two flashlights to Claudia and the Doctor before they continue looking around.

"What's your name?" The Doctor asked Osgood.

"Osgood."

"No, no, no. Your first name?"

"What's your first name?"

"Basil," he blurted.

"Petronella," she replied.

"Petro or Nella?" Arthur asked further, needing to know which Zygon (if she is a Zygon) he's talking to.

A door opens nearby and something squelches. They run to find a Zygon, who in turn runs into a general store to try and hide. It turns back into the man from earlier, but not completely.

"We can help you," the Doctor assured him.

"It wasn't me. They attacked me. They saw me. I had to," he stuttered, trying to change, but getting worse.

"It's okay," Arthur kindly said, trying to calm the poor man.

"A commander came. She turned me back!" He yelped in pain!

"We can help. We can help you," Osgood asserted before looking at the Doctor. "Doctor, Claudia, we can help him, can't we?"

"I don't know," Claudia admitted as a burst of electricity to the Doctor, who managed to avoid it, but failed to stop the man from running.

"Please! Come back!" The Doctor shouted as they all followed him to the storage room. "I can't help you just now, but—"

Another bolt of electricity appears and almost grazes Osgood. The woman staggered back, a bit shocked.

"Why?" He demanded. "I was happy like this. I was happy here."

"I understand," Claudia told him.

"I can't change. I can't hide."

"Let us help you," Osgood pleaded.

"No! You're Truth or Consequences."

"We're not. We're really not."

He transforms a little more, only to make his skin getting worse. "I'm not part of your fight. I never wanted to fight anyone, I just wanted to live here. Why can't I just live?"

"We're on your side," Arthur assured him. "Please, let us help you!"

He shook his head. "I'm not on anyone's side. This is my home."

"Listen," the Doctor makes a 'calm down' gesture. "We are not them."

"I can't go back now. You've taken my life!" He yelled, holding his hand up, palm towards his own face.

"What are you doing?!" Arthur yelped.

"No, no, no! Stop! Stop! Stop!" The Doctor shouted.

The last thing he said before shocking himself is, "They will kill me."

Arthur closes his eyes as he hears his scream before it reduces, leaving only a dreadful feeling.

"There it is, Osgood. There's their plan," the Doctor informed as they walked back through the shopping centre. "Unmask everyone, provoke fear, paranoia, provoke a war."

"Doctor," Kate called, her escort now looks like UNIT soldiers.

"Kate! Are you all right?"

"Of course I am. Why wouldn't I be?"

"It's just I'd heard otherwise."

Arthur notices that Claudia takes out her dagger from her bag.

"I'm fine," Kate assured him. "Doctor, we know where the Zygon command centre is. We know where Clara's pod is. We can take you there."

"That's great. Just exactly what we're looking for," Claudia beamed with a sincere smile.

▪︎▪︎▪︎

Kate leads them to the pods, with the soldiers bringing up the rear.

"Well, they like a good cave, don't they?" The Doctor wondered. "How many of these pods are occupied?"

Kate shook her head. "We don't know."

Claudia takes a focus on the pods. "Which one is Clara's?"

"Well, that's strange. It was here before," Kate pointed at one of the spaces.

"Rather inconvenient," Arthur huffed, rolling his eyes. "Just show yourself, Zygons."

Several soldiers turn into Zygons while Kate remains the same, pulling out a communicator and putting it on loudspeaker. "The Doctor, the Explorer, and Miss Redwood are here," she said.

"Don't kill any of them. We need them to live."

"What for?"

"Because I just found out why it's called an Osgood box. There's two of them."

"Clever idea, I'll say," the Doctor shared. "Two Osgoods, two boxes. Operation Double. Sunny is just that clever."

"What's in them, Doctor? Tell me. Now!"

"One box normalises all the Zygons."

"And the other?"

"Destroys them," Claudia answered, hands in her jacket' pockets. "And before you ask, I won't tell you."

"Which box normalises the Zygons, Miss Redwood? Tell me, or your girlfriend dies."

Claudia glances at the Doctor. The man simply gives her a slight closed-lipped smile, as if he allows her to reveal something. The bluenette nodded and said, "That won't work with me. Besides, you'll only make the Doctor anger, you know? Since you're technically going to kill his granddaughter."

The entire atmosphere suddenly became silent.

"Excuse me?" Bonnie repeated.

Claudia smiles and shows Kate and the Zygon a wristwatch she had beneath her jacket. She quickly taps the watch, and immediately, transforms into a brunette woman, wearing a simple white blouse and black flannel skirt.

"That was fun," Clara Oswald remarked after taking off her voice filter from the wristwatch.

▪︎▪︎▪︎

Bonnie quickly grabs Fake Clara and glares at her. "You're messing with the wrong enemy."

Fake Clara just smirks as she slowly transforms into Claudia Redwood. "Well, it was a good switch-a-roo," she admitted. "You're not the only one who can play this game."

▪︎▪︎▪︎

Kate glances at Clara and the Doctor, dumbfounded. "How long—?"

"Since Operation Double began. Future Arthur and Delaney thought that the ceasefire might happen, so they told us to switch our place and pretend to be each other, so no Zygons or any other enemies would expect us," Osgood explained

"But I thought neither Delaney nor Claudia could shape-shift with their conditions," Arthur recalled.

"Delaney couldn't with the mono-morphia she had, but Claudia has the potential. With just proper training from me and my sisters, we help her to utilise Claudia's power as much as she can."

▪︎▪︎▪︎

"Tell me which box that normalises Zygons!" Bonnie barked.

"Oh fiiiine. If you are so desperate, it's the blue one."

Bonnie reaches out to the blue box and hits the top of the box. The lid opens to reveal a nicely carved Gallifreyan design with two red buttons, one labelled Truth, the other Consequences. "What is this?!" She demanded.

"Shocking, huh?" Claudia mocked as she opened the red box. "Do you think we're that careless?"

"Bring them to me!" Bonnie snapped to Kate.

▪︎▪︎▪︎

The Zygons advance on four of them. Kate quickly shoots them in the back of their heads. "Sorry, Doctor. Self-defence."

"You're you," the Doctor realised.

"I'm me."

"How did you survive?"

"She killed them," Arthur noted, having a flashback of a Zygon reaching for Kate and the woman shoots back five times.

"I'm sorry. I know you and your son don't approve," Kate apologised as she drops the Zygon communicator and grinds it underfoot.

"Why does peacekeeping always involve killing?" The Doctor sadly asked. "Is this the lot?"

"No, there are plenty more of them. They were the nearest." Kate looks at Osgood. "You are you?"

"I'm me," Osgood assured her.

"But human or Zygon?"

"Me."

"What are we dealing with?"

"Other than 20 million Zygons about to be unmasked and will cause massive hysterics?" Arthur retorted.

"Which leads me to a very big question," Kate said.

The Doctor rolls his eyes. "Oh, I was really hoping that it wouldn't."

"The Zee-67, Sullivan's gas, the gas that kills the Zygons… Your future son took it."

"Well, you know how he is."

"That's what's in the red box, yes?" She guessed before shaking her head. "Of course it is. If I remember rightly, it causes a chain reaction in the atmosphere. Turns every Zygon on Earth inside out."

"Let me negotiate peace," the Doctor offered. "You can't commit mass murder—"

"Then why did you leave the gas with us?"

"The boxes are safeguards for both species. You agreed to that."

"I never agreed to that."

"Yes, you did, then I wiped your memory. And you agreed to that, too. But that's why there were two Osgoods to police the ceasefire. One human and one Zygon, to keep the secrets and keep the peace."

"I'm sorry, Doctor. Truly. But the peace is failing already."

"That's not true," Arthur disagreed.

Kate didn't say anything as she led them to the Black Archive.

▪︎▪︎▪︎

"Hi! Hello! Hello!" The Doctor greeted as he and the rest all entered the Black Archive. Two Zygons already knocked down on the floor, leaving Bonnie and Claudia, standing against each other. "Oh, hello! Hi. Hi. Stop this. Stop this, please. Let me take both of these boxes away. We'll forgive, we'll forget. And the ceasefire will stand."

"No," Bonnie disagreed.

Kate goes to the red box, not even afraid when Claudia gives her squinted eyes. "Doctor, which of these buttons do I press?" Kate demanded. "Doctor, which one? Truth or consequences?"

Bonnie stands at the blue box. "Truth or consequences?"

"This is the moment we've all been waiting for. Make your mind up time!" He stated, as if this is just a host show. "One of those buttons will destroy the Zygons, release the imbecile's gas. The other one detonates the nuclear warhead under the Black Archive. It'll destroy everyone in London. Bonnie. Bonnie, sweetheart! One of those buttons will unmask every Zygon in the world. The other one cancels their ability to change form. It'll make them human beings forever."

"There are safeguards beyond safeguards," Claudia warned, still looking at Kate. "All of us did this on a very important day for us and this ceasefire will stand. Do you want to dishonour my mother's memory? Is this how you repay her?"

"You have brought nothing but problems," Bonnie hissed.

"No, she's not," Clara disagreed.

"You all are responsible for all the violence. All of the suffering."

This time, the Doctor responds. "No, we're not."

"Yes."

"No."

"Yes. You and your companions engineered this situation, Doctor. This is your fault."

"It's yours, actually," Arthur muttered with annoyance. "We only want peace, you want blood."

"I had to do what I've done," Bonnie insisted.

"So did I," the Doctor responded.

"We've been treated like cattle."

"My son was treated worse."

"We've been left to fend for ourselves."

"So's everyone."

"It's not fair."

"Oh, it's not fair! Oh, I didn't realise that it was not fair! Well, you know what? My Tardis doesn't work properly and I don't have my own personal tailor."

"The things don't equate."

"These things have happened, Zygella. They are facts. You just want cruelty to beget cruelty. You're not superior to people who were cruel to you. You're just a whole bunch of new cruel people," the Doctor exclaimed. "A whole bunch of new cruel people being cruel to some other people, who'll end up being cruel to you. The only way anyone can live in peace is if they're prepared to forgive. Why don't you break the cycle?"

"Why should we?" She dared him.

"Other than more bloodshed?" Claudia retorted.

"I want war."

"Ah. Ah, right. And when this war is over, when you have a homeland free from humans, what do you think it's going to be like?" The Doctor asked further. "Do you know? Have you thought about it? Have you given it any consideration? Because you're very close to getting what you want. What's it going to be like? Paint me a picture. Are you going to live in houses? Do you want people to go to work? Will there be holidays? Oh! Will there be music? Do you think people will be allowed to play violins? Who's going to make the violins? Well? Oh, you don't actually know, do you? Because, like every other tantruming child in history, Bonnie, you don't actually know what you want. So, let me ask you a question about this brave new world of yours," he pointed at her. "When you've killed all the bad guys, and when it's all perfect and just and fair, when you have finally got it exactly the way you want it, what are you going to do with the people like you? The troublemakers. How are you going to protect your glorious revolution from the next one?"

"We'll win."

"Oh, will you? Well, maybe, maybe you will win! But nobody wins for long. The wheel just keeps turning. So, come on. Break the cycle."

Bonnie frowns. "Why are you still talking?"

"Are you an idiot or what?" Arthur huffed. "He wants to show you why this is wrong! Even I know what he meant!"

"Do you know what I see, Explorer? I see a clueless child, who knows absolutely nothing. And I see a box. A box with everything I need. A 50% percent chance."

"For us, too," Kate reminded her as their hands poised over the buttons.

"And we're off! Fingers on buzzers!" The Doctor spreads his hands, using a mocking tone. "Are you feeling lucky? Are you ready to play the game? Who's going to be quickest? Who's going to be luckiest?"

"This is not a game!"

"No, it's not a game, sweetheart, and I mean that most sincerely."

"Why are you all doing this?" Bonnie glared at him, Arthur, Clara, and Claudia.

"Yes, I'd quite like to know that, too." Kate stares at Claudia. "You all set this up. Why?"

"Because it's not a bloody game where you can restart it, Kate!" The bluenette snapped. "Do you forget where I came from?! I came from a planet that wanted war! I came into this world with the knowledge of murdering creatures that I don't know if they deserved it! Do you think it's funny for me to see this again?!"

"This is a scale model of war," the Doctor continued as Clara and Arthur comforted the blue-haired girl. Quietly, he thanks them for doing it, because as much as he wants to do it by himself, he needs to make a point. "Every war ever fought, right there in front of you. Because it's always the same. When you fire that first shot, no matter how right you feel, you have no idea who's going to die! You don't know whose children are going to scream and burn! How many hearts will be broken! How many lives shattered! How much blood will spill until everybody does what they were always going to have to do from the very beginning. SIT DOWN AND TALK!" He takes a sigh, to calm himself, before speaking again. "Listen to me," he pleaded. "Listen, I just, I just want you to think. Do you know what thinking is? It's just a fancy word for changing your mind."

"I will not change my mind," Bonnie said.

"Then you will die stupid. Alternatively, you could step away from that box, you can walk right out of that door and you could stand your revolution down."

"No! I'm not stopping this, Doctor. I started it. I will not stop it. You think they'll let me go, after what I've done?"

"You're all the same, you screaming kids. You know that? Look at me, I'm unforgivable. Well, here's the unforeseeable. I forgive you. After all you've done, I forgive you. And do you know who taught me that? My own son," he glances at him with a proud expression. "Who forgave me for all the horrible things I said to him. He still has the heart to forgive me."

"You don't understand. You will never understand."

"I don't understand?" The Doctor laughs mirthlessly at Bonnie. "Are you kidding? Me? Of course I understand. I mean, do you call this a war? This funny little thing? This is not a war! I fought in a bigger war than you will ever know. I did worse things than you could ever imagine! And when I close my eyes… I hear more screams than anyone could ever be able to count! And do you know what you do with all that pain? Shall I tell you where you put it? You hold it tight till it burns your hand, and you say this. 'No one else will ever have to live like this. No one else will have to feel this pain. Not on my watch!'"

It was pure silence after that. They all listen to the Doctor's word, absorbing what he had just said. Even Arthur as well. The boy knows he had held so many regrets in his life, things that he will never understand.

Kate quietly closes the lid of the red box and steps back.

"Thank you. Thank you," the Doctor whispered.

"I'm sorry," Kate finally said.

"I know. I know. Thank you. " he looks at Bonnie. "Well?"

Bonnie gazes at the box in front of her. "It's empty, isn't it?" She speculated. "Both boxes. There's nothing in them. Just buttons."

"Of course. And do you know how you know that? Because you've started to think like me and my son."

Bonnie drops her hand away from the buttons.

"It's hell, isn't it? No one should have to think like that. And no one will. Not on our watch."

"Got you," Claudia muttered with a sad smile.

"How can you be so sure?" Bonnie inquired.

"Because you have a disadvantage, Zygella. I know that face," the Doctor answered.

"This is all very well, but we know the boxes are empty now. We can't forget that," Kate pointed out.

"Eh, that would be the 16th time you said that," Claudia answered as she used her sonic pen on the memory filer in the ceiling, causing Kate to lose consciousness and nearly drop to the ground if Osgood didn't catch her and lay her down against a rack of stuff.

Bonnie closes the blue box. "You didn't wipe my memory," she realised.

"I only erased Kate and your fellow Zygons," Claudia shrugged. "When they wake up, they won't remember what you've done."

"You're going to protect me?"

"You're one of us now, whether you like it, or not," Osgood remarked.

"I don't understand how you could just forgive me," Bonnie shook her head.

"Because I've been where you have," the Doctor told her. "There was another box. I was going to press another button. I was going to wipe out all of my own kind, man, woman and child. I was so sure I was right."

"What happened?"

He simply glances at Arthur, Claudia, and Clara. "I let my son stop me and let those two girls find an alternative path." He smiles. "My girls always know the best, and I will never forget it."

▪︎▪︎▪︎

"What do you mean," Arthur starts as they all enter the Tardis after saying goodbye to both Osgoods, "when you said that Claudia's your granddaughter?"

The Doctor, Clara, and Claudia just look at each other, giving a silent conversation with their gaze on each other.

"I'm afraid that's another story you'll find out very soon," Claudia remarkee.

"How soon?"

"If my calculations aren't wrong… you'll know next," the Doctor said as he set the Tardis to outer space.

"Which is…?"

"Demons Run."

Arthur's body went still. Idris words echoing back to her. Demons run when a good man goes to war. "Why?" He asked. "What happened at Demons Run?"

"A lot happened," Claudia mumbled in a sombre tone.

"I don't—"

The Doctor sighs deeply as his son disappears again, starting to feel dread as he recalling what happened back at Demons Run.
