A/N - So I made a miscalculation and the first part of this chapter should have been added to the end of the previous one. Therefore, I added the beginning of Big Bang to the end of the this chapter.

The Doctor grabbed the communicator and called River. "The TARDIS, where is it? Hurry up. What are you even doing there?"

Elise grabbed the Doctor's hand to offer him comfort. He squeezed her hand back.

"Something's using her memories. Amy's memories. You said something had been there. If they've been to her house, they could have used her psychic residue. Structures can hold memories, that's why houses have ghosts. They could've taken a snapshot of Amy's memories. But why?" The Doctor kept glancing back at the Romans.

"Projections, or duplicates. They might think they're real. The perfect disguise. They actually believe their own cover story, right until they're activated." The Doctor started pacing. "Why? Who'd do that? What for? It doesn't make sense. River? River? River, what's happening?"

Elise suddenly wished she'd gone with River instead of staying with the Doctor.

"You're flying it wrong. Where are you? What's the date reading? You need to get out of there now. Any other time zone. Just go. Well, then shut down the TARDIS. Shut down everything! But how? Why?"

A high pitched noise filled the air.

Elise watched as the Romans in the chamber with them doubled over for a second before raising back up.

"Listen to me, just land her anywhere. Emergency landing, now. There are cracks in time. I've seen them everywhere, and they're getting wider. The TARDIS exploding is what causes them, but we can stop the cracks ever happening if you just land her," the Doctor told River.

The Pandorica started to open and a white light filled the chamber.

"Well, now. Ready to come out, are we?" the Doctor asked. He put the communicator back to his ear. "Okay, just walk out of the doors. If there's no one inside, the TARDIS engines shut down automatically. Just get out of there. Run!" The Doctor soniced the Pandorica as the Romans came closer to them.

Their hands were now guns.

Elise tugged on the Doctor's jacket.

"Doctor! Doctor, I can't open the doors!" River yelled over the communicator.

The Doctor finally turned and saw the Romans. "Amy!" he yelled.

The Romans grabbed both Elise and the Doctor and walked them towards the Pandorica.

"Plastic Romans. Duplicates, driven by the Nestene Consciousness, eh? Deep cover, but what for? What are you doing? What's in there, eh? What's coming out?" the Doctor asked.

"The Pandorica is ready," one of the Romans said.

"What, do you mean it's open?"

"You have been scanned, assessed, understood, Doctor," a Dalek voice said.

"Scanned? Scanned by what, a box?" the Doctor asked.

"Your limits and capacities have been extrapolated."

Cybermen and a couple of other alien species that Elise didn't recognize appeared in the chamber.

"The Pandorica is ready!" The alien that spoke was short and brown.

Elise had never seen so many different species before, but she wasn't scared. The only real thing that scared her were Daleks.

"Ready for what?" the Doctor asked.

"Ready for you," the white Dalek said.

Two Romans dragged the Doctor to the Pandorica as Elise screamed. The Romans locked the Doctor into the seat.

"What do we do with this one?" the brown alien asked, pointing his gun at Elise.

"Scan reveals the child is Timelord", the white Dalek said.

Elise struggled against the Romans.

"The child will be confined with the Doctor".

Elise was picked up and carried to the Pandorica where they shackled her wrists and ankles together at the Doctor's feet.

"You lot, working together. An alliance. How is that possible?" the Doctor asked.

"The cracks in the skin of the universe," the White Dalek said.

"All reality is threatened," the brown alien added.

"All universes will be deleted."

"What? And you've come to me for help?" the Doctor asked.

"No. We will save the universe from you and your offspring!" the brown alien said.

"From me?"

"All projections correlate. All evidence concurs. The Doctor will destroy the universe," the Cyberman said.

"No, no, no. You've got it wrong."

"The Pandorica was constructed to ensure the safety of the Alliance."

"A scenario was devised from the memories of your companion," the White Dalek told him.

"A trap the Doctor could not resist," the brown alien said.

"The cracks in time are the work of the Doctor. It is confirmed."

"No. no, no, not me, the TARDIS. And I'm not in the TARDIS, am I?" the Doctor asked.

"Only the Doctor can pilot the TARDIS."

"Please, listen to me!"

"You will be prevented."

"Total event collapse! Every sun will supernova at every moment in history. The whole universe will never have existed. Please, listen to me!"

"Seal the Pandorica," the Cyberman said.

"No! Please, listen to me! The TARDIS is exploding right now and I'm the only one who can stop it! Listen to me!"

The Pandorica doors closed. Inside the Pandorica, it was deadly silent.

The Doctor slammed his head into the headrest behind him in frustration.

If they were going to be stuck in here till the end of time, Elise would have to do something she'd been terrified of doing. "Daddy?"

The Doctor froze, hearing Elise's voice. He'd never heard her voice before. Well he had, but that was a long time ago. But this version of her had never spoken on purpose before. "Yes, love?" he said.

"I'm scared".

"I don't know how, but I will get us out of here."

"How?"

"Do you trust me?"

Elise nodded and said, "Yes".

But only a few minutes later, the doors to the Pandorica opened and Rory stood there holding the Doctor's sonic screwdriver.

The Doctor was released from the chair. "How did you do that?"

"You gave me this," Rory told him.

The Doctor pulled out his own sonic screwdriver. "No, I didn't."

"You did. Look at it."

The Doctor quickly soniced Elise's restraints before they stepped out of the Pandorica. He touched his screwdriver to Rory's and they sparked. "Temporal energy. Same screwdriver at different points in its own time stream. Which means it was me who gave it to you. Me from the future. I've got a future. That's nice." He pointed to the fossilized Daleks. "That's not."

"Yeah. What are they?" Rory asked.

The Doctor looked at Elise and gestured for her to answer the question. She shook her head and he nudged her.

"They're called Daleks," she said.

Rory's mouth dropped open. "Oh my god. She can talk."

Elise rolled her eyes.

"Bigger picture here, Rory. History has collapsed. Whole races have been deleted from existence. These are just like after-images. Echoes. Fossils in time. The footprints of the never-were," the Doctor explained.

"Er, what does that mean?"

"Total event collapse. The universe literally never happened."

"So, how can we be here? What's keeping us safe?"

"Nothing. Eye of the storm, that's all. We're just the last light to go out. Amy. Where's Amy?"

Rory led them outside.

Amy was lying on the ground not moving.

"Auntie Amy!" Elise said, dropping to her knees next to her.

The Doctor knelt down and put his fingers on her throat.

"I killed her," Rory said.

"Oh, Rory."

"Doctor, what am I?"

"You're a Nestene duplicate. A lump of plastic with delusions of humanity."

"But I'm Rory now. Whatever was happening, it's stopped. I'm Rory."

"That's software talking."

"Can you help her? Is there anything you can do?"

"Yeah, probably, if I had the time."

"The time?"

"All of creation has just been wiped from the sky. Do you know how many lives now never happened? All the people who never lived? Your girlfriend isn't more important than the whole universe."

Rory punched the Doctor, sending him to the ground. "She is to me!" Rory yelled.

"Dad!" Elise gasped, "Rory!"

The Doctor jumped to his feet. "Welcome back, Rory Williams! Sorry. Had to be sure. Hell of a gun-arm you're packing there. Right, we need to get her downstairs. And take that look off your plastic face. You're getting married in the morning."

Rory carried Amy down into the Pandorica chamber and the Doctor placed her in the chair.

"So you've got a plan, then?" Rory asked.

"Bit of a plan, yeah. Memories are more powerful than you think, and Amy Pond is not an ordinary girl. Grew up with a time crack in her wall. The universe pouring through her dreams every night. The Nestenes took a memory print of her and got a bit more than they bargained for, like you. Not just your face, but your heart and your soul." The Doctor placed his hands on Amy's face and closed his eyes. "I'm leaving her a message for when she wakes up, so she knows what's happening." The Doctor soniced the Pandorica, sealing Amy inside.

"Whoa, whoa, whoa, whoa. What are you doing?" Rory asked.

"I'm saving her. This box is the ultimate prison. You can't even escape by dying. It forces you to stay alive."

"But she's already dead."

"Well, she's mostly dead. The Pandorica can stasis-lock her that way. Now, all it needs is a scan of her living DNA and it'll restore her."

"Where's it going to get that?"

The Doctor checked his watch. "In about two thousand years." The Doctor pulled out a Vortex Manipulator from his pocket and strapped it to his wrist.

"She's going to be in that box for two thousand years?" Rory asked.

"Yeah, but we're taking a shortcut. River's vortex manipulator. Rubbish way to time travel, but the universe is tiny now. We'll be fine," the Doctor told him.

"So hang on. The future's still there, then. Our world."

"A version of it. Not quite the one you know. Earth alone in the sky. Let's go and have a look."

The Doctor raised his wrist. "You put your hand there. Don't worry. Should be safe."

"That's not what I'm worried about."

"She'll be fine. Nothing can get into this box."

"Well, you and Elise got in there."

"Well, there's only two of us. I counted."

"This box needs a guard. I killed the last one."

"No. Rory, no. Don't even think about it."

"She'll be all alone."

"She won't feel it."

"You bet she won't."

"Two thousand years, Rory. You won't even sleep. You'd be conscious every second. It would drive you mad."

"Will she be safer if I stay? Look me in the eye and tell me she wouldn't be safer."

"Rory, you..."

"Answer me!"

"Yes. Obviously."

"Then how could I leave her?"

The Doctor sighed. "Why do you have to be so human?"

"Because right now, I'm not."

The Doctor typed in the date he wanted and the Vortex Manipulator started beeping. He grabbed Elise's hand. "Listen to me. This is the last bit of advice you're going to get in a very long time. You're living plastic, but you're not immortal. I have no idea how long you'll last. And you're not indestructible. Stay away from heat and radio signals when they come along. You can't heal, or repair yourself. Any damage is permanent. So, for God's sake, however bored you get, stay out of..."

The Doctor and Elise vanished and Rory took his place guarding the Pandorica.
