Standing in the doorway, looking slightly confused, is Clara Oswald. Sophie smiles, as the Bow tie Doctor looks gobsmacked, "How did you do that?"

"It wasn't locked," the teacher shrugs.

"Right."

Sophie snorts from where she's leaning against the wall. The pinstripe Doctor shoots her a look, and she smiles cheekily at him.

"So they're both you, then, yeah?" Clara asks, leaning toward her Doctor.

"Yes. You've met them before. Don't you remember?"

"A bit," she shrugs, turning to look at Sandshoes, "Nice suit."

"Thanks."

"Hang on. Three of you in one cell, and none of you thought to try the door?"

"See, that's what I've been thinking."

"You've been trapped here too!" Sandshoes grumbles, faking annoyance. "You could have easily checked the door yourself."

"Didn't think that was at all necessary, seeing as I'm trapped in here with three Doctor's. You all seemed so sure that we were trapped. It was very convincing."

"It should have been locked," the Warrior grunts.

"Yes. Exactly. Why wasn't it locked?" Chinny concurs, looking at the door.

"Because I was fascinated to see what you would do upon escaping," the Elizabeth says, stepping into the cell. "I understand you're rather fond of this world. It's time I think you saw what's going to happen to it."

The Queen leads the group from the cell up a few levels of the tower. They enter a dimly lit room, filled to the brim with Zygons. Sophie crinkles her nose as the stench of the suckery aliens fills her nostrils.

"The Zygons lost their own world. It burnt in the first days of the Time War. A new home is required," the Elizabeth informs the squad.

"So what, they want this sh*th*le?" Sophie questions just to get glares from three Time Lords.

"Not yet. It's far too primitive. Zygons are used to a certain level of comfort."

"Commander, why are these creatures here?" the alien hisses.

"Because I say they should be. It is time you too were translated. Observe this. I believe you will find it fascinating."

The creature sets his hand on a small glass cube with dents in the sides that rests on a small table. The Zygon vanishes from the room, as a figure materializes in the painting hanging from the wall.

"That's him!" Clara gasps, leaning toward her Doctor, "That's the Zygon in the picture now."

"It's not a picture, it's a stasis cube," the War Doctor shakes his head, "Time Lord art. Frozen instants in time, bigger on the inside, but could be deployed as–"

The pinstripe Doctor cuts him off, "Suspended animation. Oh, that's very good. The Zygons all pop inside the pictures, wait a few centuries till the planet's a bit more interesting, and then out they come."

"Seriously?" Sophie asks, raising an eyebrow. "That sounds boring. Also, why in the name of sanity would you want to invade earth in the future. It's bad now. What, do you really think humanity is just going to improve their ways, and the world's gonna improve?"

The oldest Doctor glances at her out of the corner of his eye, proceeding to roll them both. "You see, Clara, they're stored in the paintings in the Under Gallery, like cup-a-soups," he waves his hands in front of his face, "Except you add time, if you can picture that. Nobody could picture that. Forget I said cup-a-soups."

"And now the world is worth conquering. So the Zygons are invading the future from the past."

"Exactly."

"Okay, but earth is a rubbish place to invade, no matter the era. Except maybe when the dinosaurs, and Silurians ran the planet. Then again, no one would've invaded then, because Silurian's were totally bad*rses."

This time Sandshoes rolls his eyes at his friends' antics, before he leans toward the Queen, "And do you know why I know that you're a fake? Because you're such a bad copy. It's not just the smell, or the unconvincing hair, or the atrocious teeth, or the eyes just a bit too close together, or the breath that could stun a horse. It's because my Elizabeth, the real Elizabeth, would never be stupid enough to reveal her own plan. Honestly, why would you do that?"

"Because it's not my plan. And I am the real Elizabeth," she argues.

Sophie holds back her laugh at the look of terror that skirted across the Time Lords face, "Okay. So, backtracking a moment just to lend context to my earlier remarks."

"My twin is dead in the forest. I am accustomed to taking precautions." From within the folds of her skirt, she pulls out a dagger, showing it to the squad.

Sophie smiles, "See. I knew there was a reason I liked you. Of course, I carry a sword. but a dagger is definitely less conspicuous."

Sandshoes turns, "Can you please stop talking before you get yourself killed?"

"These Zygon creatures never even considered that it was me who survived rather than their own commander," Elizabeth says, side-eyeing the girl. "The arrogance that typifies their kind."

"Zygons?" Clara asks.

"Men."

"And you actually killed one of them?" the teacher asks, sounding impressed.

"I may have the body of a weak and feeble woman, but at the time, so did the Zygon." Turning to look at the pinstriped Doctor, she continues, "The future of my kingdom is imperilled. Doctor, can I rely on your service?"

"Well, I'm going to need my TARDIS."

"It has been procured already."

"Ah," he nods, smiling at the Queen.

"But first, my love," Elizabeth continues, her hand touching his cheek gently, "you have a promise to keep."

Sophie physically places her hands over her mouth so she doesn't burst out laughing. Her whole body shakes as she holds back the laughter. The eldest Doctor turns, merely shaking his head at her. He slowly just runs her back until her laughter subsides and she begins to breathe normally again.

It's not even ten minutes later that the squad are up on the palace lawn, a wedding canopy over the heads of Sandshoes and the Queen. "I think this may have been the fastest wedding set up I've ever seen," Sophie mutters, leaning toward Clara, "And I've been to Vegas."

The teacher smiles over at her, "I love weddings, don't you?"

"Oh yeah," the girl grins, "Especially when it's an embarrassing mistake the Doctor made. That makes weddings so much better."

"I've only met you once y'know," Clara says, "But I just jumped into his time stream, which you'll find out about later, but I saw you way more times than I expected."

"Oh yes. We've been together through thick, and through thin."

The Doctor's standing near each other look at Sophie, each one smiling.

"I now pronounce you man and wife," the clergyman says, loudly. Sophie's head turns back to the wedding, Clara cheering, and throwing confetti onto the new couple's heads, while the clergyman adds, "You may kiss the bride."

The Queen grabs the Time Lord's face, pressing her lips firmly against his, very enthusiastically.

"Is there a lot of this in the future?" the Warrior asks, turning to his older self.

"It does start to happen, yeah."

Elizabeth pulls back from her husband, keeping her hand entwined with his. "God speed, my love."

He starts away, releasing her hand, "I will be right back," he calls to her, while running to his TARDIS.

Sophie tuts, following him into the ship, "Wow, you're starting your relationship with lies. No wonder she wants to behead you."

"She makes a good point," his older self states, "That does explain a lot."

The pinstriped Time Lord ignores them, flipping a few switches on the console, "Right then, back to the future."

Sophie smirks, "Great scott, Doc."
