"Welcome to the Under Gallery. This is where Elizabeth the First kept all art deemed too dangerous for public consumption," said Kate as they made their way past the painting and through a secret door.

John noticed a strange crunching noise under his feet upon walking through the gallery. Bending down, he scooped up the peculiar sand.

"What's this?" he asked. Unsure if it was even worth noting.

Kate turned to him with a raised brow and a hint of annoyance at how easily "the Doctor" seemed to get distracted.

"Is it important?" she asked.

John shrugged his shoulders. "Honestly, I don't know if it's important, but it's definitely odd."

Citana knelt down and grabbed John by the arm to move him further into the strange exhibit.

John's eyes immediately were drawn to a red fez sitting in a display case. Without much thought, he picked it up and plopped it on his. Then, he held his arms out in front of Citana. "Eh?" he giggled. He then pointed to his head. "Fez."

Citana merely rolled her eyes as they kept walking.

The next room they entered had glass all over the floor, with more strange 3D paintings along the wall.

Kate was the first to speak. "This is why we called, er, brought you in."

Without any headaches or sense memories, John could still easily see that the shatter pattern of the glass indicated that something had broken out of the paintings.

"Interesting," was all he said.

"What? The broken glass?" questioned Citana.

"No, where it's broken from. Look at the shatter pattern. The glass on all these paintings has been broken from the inside."

"As you can see, all the paintings are landscapes. No figures of any kind," replied Kate.

"So?" said Citana.

"There used to be." Kate then handed them a picture of the original image.

"That…that is creepy," said John, trying not to freak out.

"We've searched the whole place but haven't found anything amiss."

Suddenly, an odd wormhole appeared out of thin air.

"What the hell is that?" exclaimed Citana, backing up against the wall.

"Does it have to do with the paintings?" asked Kate, with slight fear in her voice.

"Um, well, I honestly don't know." John then threw the fez into the strange portal.

"Oh, god. John, what the hell are you thinking right now?" Citana could tell by the look on his face he was about to do something stupid.

"I'm not thinking anything! Geronimo!" he yelled as he leapt into the hole.

Both Citana and Kate cried out simultaneously. "Wait!"

…

"Doctor! That's too hard!" Clara winced. "John is by far better at this than you."

"Oi! I'm sorry if I'm not massaging your feet to your liking, Clara. I didn't realise the art of massaging one's feet was so difficult," the Doctor huffed in an annoyed tone.

"I asked you to massage my feet because they are sore, not to make them sore," she laughed.

They were lounging on the sofa and taking advantage of having the flat to themselves.

"Go on," said Clara. "I know you're dying to call the TARDIS back. Your leg is bouncing up and down like you've had 10 espresso shots.

"Really? I mean, I don't want you to think I haven't enjoyed…going the long way round with you. I really have, but…."

"You need to travel. I get it. And I'd be lying if I said I didn't miss the Old Girl myself. Besides, it's probably about time we checked in on John before he goes and rewrites history or…Doctor? What is it? Why are you looking at the telly like…." Clara turned her head just in time to see the local news report. Apparently, "Derren Brown" was pulling another stunt and flying about London in a blue police box, hooked to a helicopter.

"Oh, my God. That has to be the TARDIS!" gasped Clara in surprise.

The Doctor grabbed Clara's hand and dragged her out of the flat without a word.

"Doctor! Where are we going!"

"UNIT. This isn't the first time they've blamed that poor illusionist on one of their stunts. Er, I may have had something to do with it that time. But still! They're involved, and if they find out that John exists…" his face paled as he turned to Clara. "Clara, if UNIT or anyone finds out that there's another Time Lord. And specifically, one genetically identical to me. I dread to think what they'd do to him. Come on!"

…

John instantly felt himself land harshly onto the ground. "Shit," he croaked out. When he finally regained his breath, he slowly began to sit up and look around. His head turned when he heard a woman's voice.

"Who is that man?"

"That's just what I was wondering."

John stood up and took in the sight of the Doctor's previous face, along with who he could only assume to be Queen Elizabeth I. He also noticed that the Doctor was wearing the red fez.

"Oi! That's mine!" John then swiftly snatched the fez and put it back on his own head.

The man gave him an odd look. "You're not?" he then pulled out his sonic screwdriver. Without thinking, John reached into the pocket of the Doctor's tweed and pulled out a sonic of his own.

"What the hell?" he whispered. Then remembering he was supposed to "play Doctor," he straightened and held out the sonic. It looked exactly like the current Doctor's sonic, only the light was blue like the Tenth Doctor's.

"Compensating?" joked Ten.

"For what?" asked John, completely missing the joke.

"Oh, you know. Regeneration. It's a lottery." He had a smug look on his face.

"Oh, he's cool. Isn't he cool? I'm the Doctor, and I'm all cool. Oops, I'm wearing sandshoes."

"At least I don't look like I'm some kind of child who dresses like his grandfather!"

"Ah! Yes! Thank you! I tell him…er, I mean…."

Ten was now eyeing John suspiciously. "Tell him…who?"

"Oh, um…" John then noticed he was seeing double. Double Queens.

"Hello, ladies."

Ten sighed. "Ah, right. One of them is a Zygon," he then looked back to John. "Hang on. Are you sure you're future me? How do I know you aren't a Zygon or something?"

"Well, for one, there isn't two of me so…."

**THUD**

The Tenth Doctor took a step back from the time fissure, now seeing a second bow-tie wearing man land right on top of the other.

"Isn't two of you?" Ten said with a raised eyebrow.

…

"So this is UNIT?" asked Clara as they entered the building.

"Yes! And I'm currently trying to track John's genetic code with my sonic. It seems as though he's in the Under Gallery."

The Doctor and Clara walked the same path as John and Citana had only moments before. The Doctor's eyes went wide when he heard a familiar voice yell out, "Geronimo." When both Clara and the Doctor entered the room, they were met with equal faces of shock staring between them and the fissure.

"How? Doctor! I just saw you jump in there. How are you here now?" questioned Kate.

"Ah, the man who just jumped in the time fissure, did he have my face?"

Citana's head perked up at the odd question.

"Yes. Your face and the same outfit you are wearing right now. Are you saying that wasn't you?"

Both Clara and the Doctor gave each other funny looks then turned their backs to have a private conversation. "Give us a mo," said Clara nervously.

"Clara, what if that wasn't John? What if I crossed my time stream? Why would he wear my clothes?"

"Good question. Maybe ask how you were behaving or something? Any clues as to if John is pretending to be you?"

They both turned towards the women, who still held confused looks on their faces.

"Um, Kate, how did I behave? Was I acting…different? Saying things that I wouldn't normally say?"

Kate thought it over. "As a matter of fact, yes. You told me you were out of your depth. And you…cursed."

The Doctor and Clara simultaneously looked at each other and rolled their eyes, now knowing it was definitely John who jumped through the time fissure.

"Wait. Doctor? What is going on?" asked Kate.

"Oh, you know…" he wrung his hands together, trying to think of an explanation. "Zygon… big ugly red fellows. Don't worry. I'll be back in a mo!"

"Wait!" yelled the women.

Citana didn't know what to make of the odd exchange. The Doctor, or John, or whoever that was, didn't even seem to recognise her, let alone give her the time of day.

"Okay, can someone please explain to me what the hell is going on?"

Kate sighed, "Well, it appears as though you were the travelling companion of a shapeshifting Zygon. Not the Doctor."

She then turned to the fissure and spoke. "Doctor? Can you hear me?"

Citana slumped against the wall. Was John really some kind of shapeshifter? Maybe that's why…Her thoughts were interrupted by the petite brunette who had accompanied the actual Doctor.

"Hey, are you alright?" questioned Clara.

Meanwhile, Kate seemed to be in conversation with the Doctor, and all seemed well for the most part.

"Well, I thought the guy I'd been hanging out with was just a normal guy. Well, alien. Time machine and everything but…."

"Did he tell you his name was John?"

"Yeah."

Clara took Citana's hand and guided her to a more secluded area to make sure no one could hear.

"He wasn't lying," said Clara in a hushed voice.

"Wait? What?"

"It's a bit…complicated, but, John. He's…well, kind of like a kid brother to the daft alien that just jumped through that wormhole thing-y."

"Why'd the Doctor call him Zygon then?"

"He's afraid of what would happen if anyone, even UNIT, found out there was another of his kind."

Citana made a confused face. Then laughed to herself.

Clara was caught off guard by the change in emotion. "Um, what's so funny?"

"The Wanker…" she was giggling now. "John's weird futuristic cell phone was ringing." She paused and shook her head. "I took it from him. It said, "the Wanker" was calling. He said it was his brother. I take it he meant the Doctor, right?"

Clara rolled her eyes. "Yes, seems about right." She sighed. John sure knew how to make a right mess of things. Yet, so could the Doctor.

"So, what do we do now?" asked Citana.

"For now, we are going to pretend John is a Zygon while the Doctor gets this all sorted."

"Right, right. Okay. I can do that."

Clara eyed the young woman up and down. "So, how exactly did you meet, John?"

"Strip club," was all Citana said with a wry smile.

"Oh, um, well… can't say that I'm surprised actually." She then stuck her hand out. "My name is Clara. I've been knocking about with the two knuckleheads for a while."

Citana took the shorter woman's hand. "Nice to meet you, Clara. My name is Citana. I've been hanging out with John for the past few hours…or days. Not really sure."

There was an awkward silence as Citana and Clara turned their attention to Kate.

"I think there's more of them now," said Kate with a puzzled look on her face. "Only, I think the other two are different versions of him."

"Am I talking to the wicked witch of the well?" rang the Doctor's voice.

"I think he means you," said Kate to Clara.

Clara just rolled her eyes and grumbled. "Why am I the witch?"

"Clara?" came his voice again.

"Hello?" responded the bossy brunette.

"Clara, hi, hello. Hello. Would you mind telling these prattling mortals to get themselves begone?"

"What he said."

"Yes, tiny bit more colour."

"Ah, yes, of course, darling. Just say the magic word," Clara smirked.

"Oh, for fuck's sake, Clara! Please?" came John's voice.

"Oi, don't talk to her like that."

"Can someone explain to me what is going on…"

Clara turned to Citana and Kate. "I think they're all fighting."

Citana huffed and rolled her eyes. "Jesus, Christ."

Clara turned back to the fissure. "Right. Prattling mortals, off you pop, or I'll turn you all into frogs!"

"Ooo, frogs. Nice. You heard her."

"Doctor, what's going on?" asked Clara.

…

Woods 1562

"It's a timey-wimey thing," replied the Doctor through the fissure.

"Timey what? Timey-wimey?" asked the younger incarnation of the Doctor. He now also joined in on the "fun".

"I've no idea where he picks that stuff up," said Ten.

"Oh, you have no idea. One time…" began John.

"Shut up, John," said the Doctor.

"You know, I like him. Why can't we end up more like him instead of you?" laughed Ten.

The Doctor made an annoyed face in response. It took a while, but the Doctor was finally able to explain who John was to Ten. Only to again explain it all to "granddad".

Suddenly, the soldiers all started to kneel, leaving only the three Doctors and John standing in front of the supposed Queen.

"You don't seem to be kneeling. How tremendously brave of you," she said with an air of arrogance.

Ten spoke first. "Which one are you? What happened to the other one?"

"Indisposed. Long live the Queen," she replied cheekily.

"Long live the Queen!" shouted the soldiers.

"Arrest these men. Take them to the Tower."

"That is not the Queen of England. That's an alien duplicate!" shouted Ten.

"And you can take it from him, cos he's really checked," said the Doctor.

John snorted a laugh.

"Oh, shut up!" hissed Ten.

"No, hang on. Did you say the Tower? Ah, yes, brilliant. Love the Tower," said the Doctor causing John to raise an eyebrow.

"When you say "Tower," you don't happen to mean the scary place where they lock people in chains, do you?" questioned John in a worried tone.

"The one and only!" replied the Doctor. He turned back to the Queen. "Breakfast at eight, please. Will there be Wi-Fi?"

"Are you capable of speaking without flapping your hands about?" questioned the older looking Time Lord.

"Yes. No. I demand to be incarcerated in the Tower immediately with my co-conspirators Sandshoes, Granddad and Whippersnapper."

"Granddad?"

"They're not sandshoes," grumbled Ten.

John just shrugged. "Mine could have been a lot worse, to be honest."

"Silence," began the Queen. "The Tower is not to be taken lightly."

…

The four men were now pacing about the dirty cell, figuring out how to escape.

"Okay, so the Queen of England is now a Zygon. But never mind that. Why are we all together? Why are we all here? Well, me and Chinny times two, we were surprised, but you came looking for us. You knew it was going to happen. Who told you?"

"Oi, Chinny?" exclaimed the Doctor.

John just chuckled.

"Ah, mate. He's got a point," the young Time Lord said as he felt his own chin.

Ten just smiled at John.

…

John watched the three different versions of the Doctor arguing. The current Doctor was also carving something into the wall. It was a bit bizarre to see how different each of them were. He'd assumed the only thing that changed during the regeneration process was the body. Not an entire personality.

'I wonder if I'll change personality if I ever regenerate.' John shuddered at his thought. It was one thing for a Time Lord to grow up understanding the ins and outs of regeneration. But, how would he handle it, not having any formal training or much knowledge on the subject?

Suddenly, the voice of Granddad broke John out of his thoughts.

"Do you have to talk like children? What is it that makes you so ashamed of being a grown-up? Oh, the way you both look at me. What is that? I'm trying to think of a better word than dread."

"It must be really recent for you," said Ten.

Granddad had a puzzled look on his face. "Recent?"

Eleven now cut in. "The Time War. The last day. The day you killed them all."

"The day we killed them all," Ten corrected.

"Same thing." Eleven continued his carving.

John could feel the tension rising in the room. "Gahh!" Once again, he had a flash of pain. But then, it was gone.

Eleven and Ten turned to John with concerned looks on their faces while Granddad seemed to be staring at nothing.

Finally, Granddad spoke, "I don't talk about it."

Ten turned to him and cocked his head. "You're not talking about it. There's no one else here."

"Did you ever count?" Grandad asked hesitantly.

"Count what?" asked Eleven.

"How many children there were on Gallifrey that day."

The Doctor suddenly halted the incessant scratching before speaking.

"No idea."

John's brow furrowed. Before he could say anything, Granddad spoke again.

"How old are you now?"

"Ah, I don't know. I lose track. Twelve hundred and something, I think, unless I'm lying. I can't remember if I'm lying about my age. That's how old I am."

"Four hundred years older than me, and in all that time, you've never even wondered how many there were? You never once counted?" said Granddad. John caught a trace of disappointment in his voice.

"Tell me, what would be the point?" spat Eleven.

"Two point four seven billion," said Ten.

"You did count!" exclaimed Granddad.

"Yeah, and apparently, it will only four hundred years for me to forget," said Ten looking over at Eleven.

Before Eleven could speak, John finally entered the conversation.

"He didn't forget."

The three Doctors finally turned their attention to the youngest member of the crew.

"It's all in here now." John pointed to his temple. "I get these flash headaches, and then I've got memories. Not mine. Well, not really. His," he gestured to Eleven. "You said two point four seven billion, right? That's how many children." John stood up, walked over to Eleven, and stood between him and Ten. He closed his eyes and spoke. "One point four billion girls. One point one seven billion boys. Seven hundred and eighty-six million were under the age of thr…."

"STOP!" yelled Eleven. John's eyes flew open.

"I'm sorry," he said quietly.

Granddad gestured for John to come near him. "Come here, boy."

John hesitantly made his way next to Granddad and sat down. The older man looked into John's eyes, making him grow uncomfortable. It felt like the man was looking into his soul. Which, John still wasn't entirely convinced he had a soul, being a clone and all.

"Interesting," the old man began. "You carry the knowledge but none of the burden."

John tilted his head in confusion. "What knowledge? I feel like I don't know anything. I'm just…reacting."

"How old are you?"

Eleven made a sound of annoyance.

"Shhh," began Ten. "He's about to make a point."

"I'm twenty-one. I think. At least from the time I've had this brain. Or, mind or I don't really know what to call it."

The old man seemed to ponder for a moment. "As terrible as it is to see these two are my future, it's comforting to know that there's some version of me living a life without the burden I've brought upon myself."

"But, I'm not you. Or, them even. I'm just…well, me."

"You said so yourself. It's all in there," Eleven pointed to John's temple with a small smile.

"And honestly, I think you'd make a far better Doctor than this one here," said Ten playfully whilst pointing to Eleven.

Instead of a clever comeback, the Doctor finished up his engraving. He then began to laugh.

"What is it?" asked John.

"Sorry. Something just occurred to me," he said as he pulled his sonic out.

…

John watched as the three Doctors began pointing their sonics at the door. He thought about taking out the sonic he'd found in the pocket of the uncomfortable tweed but feared the Doctor would confiscate it from him. Best not let him know he's discovered it yet.

"Hey, four hundred years in four seconds. We may have had our differences, which is frankly odd in the circumstances, but, I tell you what, boys. We are incredibly clever."

Suddenly, the door swung open with none other than Clara on the other side.

"You gotta be shitting me," laughed John.

All three Doctors and Clara were now glaring at him.

"What? The door was obviously unlocked this entire fucking time, and none of you Doctors thought to check the door?" he sighed.

They were all still glaring, but Clara was also trying not to laugh.

John huffed, "Oh, come on. I'm supposed to be the dumb and irresponsible one. Don't look at me like that!"

…

The Doctor, Granddad, John and Clara all stood and watched as the Tenth Doctor said his "I Dos" to Queen Elizabeth I.

"I now pronounce you man and wife," said the priest.

"Woo hoo!" shouted Clara. She was getting a kick out of the thought that the Doctor had to be tied down in wedlock against his will.

"You may kiss the bride."

Queen Elizabeth then proceeded to bring Ten into a rather enthusiastic kiss. Clara continued to whistle.

"Is there a lot of this in the future?" questioned Granddad.

"It does start to happen, yeah," whispered the Doctor.

John piped in. "Oh, yes. Just ask miss Clara over there. A lot more than kissing…OW!" John jumped and grabbed his foot that the Doctor just stomped on while Granddad's eyes went wide as he looked to Clara, who was giggling in embarrassment.

"Okay, enough of that. Back to the future!" yelled the Doctor as Ten ran to the TARDIS.

…

In Ten's TARDIS, the Doctors were bickering over interior decorating while John pulled Clara aside.

"Um, Clara, when you were with UNIT. You didn't happen to meet a…er, girl there?"

Clara gave a wry smile. "Is she tall and gorgeous with long black hair and a Pearl Jam t-shirt?"

John gave a nervous laugh. "Erm, yeah…that…that sounds like her."

"Citana, right?"

John nodded with a grin.

"Yes, she was there. She'd gone to help Osgood study some weird stone dust. I got a bit caught up with some Zygons in the Black Archive."

"Is she safe? I… I'd hate to drag her into all this, and she gets hurt," he winced a bit at the memory of her bleeding out on the dark New York street.

"I'm sure she's fine. And now there's three of them, so…" she paused. "I'm sure she's fine," she laughed.

…

Citana was running. Running from…herself? Once she figured out John was an alien, she knew she'd probably have a few fascinating stories to add to her diary. But this? This was weird.

"Shit," she hissed as she hid behind a wooden crate.

"I know you're in here!" Citana's own voice rang out in the room. She could hear the imposter's footsteps approaching.

Citana looked around to see if she could use anything as a weapon.

'Dammit,' she thought. There was nothing. She peered around the corner and saw the Zygon had moved out of the doorway. It gave enough room for her to make a run for it. She'd have to be quick, though. Citana took a deep breath and counted to three.

"Hey" yelled the Citana Zygon. Citana could feel her own hands barely grasp onto her shirt. Luckily, she was quick enough to make it through the door.

"Holy, shit. Holy, shit!" she kept repeating under her breath. She could sense the Zygon was right on her tale.

Suddenly, she came to a large door. "Oh, god, please be unlocked!" Sure enough, the door was unlocked, and Citana bolted right through the door.

Citana was now barreling into the Black Archive. Clara, John and the Doctors were all in the room already. The Zygon's had just made a peace treaty with the humans. Unfortunately, there was still the rogue Zygon chasing Citana.

A young UNIT soldier followed Citana's screams into the Black Archive, where someone yelled, "shoot the Zygon!"

Before anyone could stop the soldier from pulling the trigger, there was a loud BANG.

…

"Oh, my God!" cried Clara.

The Doctor ran over to her.

Citana gasped in horror when she realised what had happened. She looked over and saw the Zygon version of herself already in custody, then quickly turned her eyes back to the scene before her.

"Is…is he going to be okay?" she asked.

John was now lying on the ground clutching his chest as the blood poured out. His eyes were wide as he was shaking.

"John, hey, look at me. It's okay, you're going to be fine," reassured the Doctor.

Clara was crying as the Doctor took her hand.

"Do something!" yelled Citana. "How can you say he's going to be fine if you're just going to watch him bleed out!" She couldn't help but sob when she saw the light leaving his eyes.

"Everyone get back!" shouted the Doctor. Suddenly, John's body began glowing.

"Is…is he regenerating?" asked Clara.

"Yes, he is," said the Doctor.

Everyone took shelter as John's body began to emanate a blinding light.

"I don't envy him," said Ten as they all went into another room. "Hurts like hell," he whispered to Citana.

…

John felt like every nerve was on fire. He couldn't help but yell out as the regeneration energy flowed through him. It felt like an eternity when it was only moments in reality. But then, the pain was gone. Not only was the pain gone, but he also felt refreshed. Like he'd gotten a good night's rest and then some.

He slowly opened his eyes.

"Citana?" he questioned. She was staring at him with wide eyes. He then looked to her left and saw the Doctor's face looking at him with a slight smile. And then to the right of Citana was Clara. Her makeup was all over the place from crying.

"Oh, god. I'm hideous now, aren't I?" he asked.

Clara hiccupped a laugh and sniffled. "Oh, nothing that a little makeup won't fix," she giggled.

John sat up straight, "What? NO! I'm a girl!" his hands flew to his chest when he noticed the three were all laughing. "Not a girl," he said in relief.

He then felt his face. "Hold up," he ran to the pane of glass and saw his reflection.

"How? I don't understand?" questioned John. He looked intently at his own reflection. Which was just that. His own. He looked exactly as he did when he woke up that morning.

The Doctor came over to him. "I have a working theory." He paused. "Why don't you and your friend head back to the TARDIS. You can ask me all the questions you want there. I've got some other business to attend to first."

John looked over to the other two Doctors. "Ah, right." He started to leave but stopped. "You don't have to, you know."

The Doctor knew exactly what John was referring to. "John, it's not that simple. There isn't any other way."

John just shrugged his shoulders. "Maybe…. or maybe you just haven't had the right inspiration." John gave a tight smile, then turned and headed to the TARDIS.
