"She did it to save me. I was cocky and stupid. She didn't want to change her past, our lives together, by letting me die. I saved her mind to the data core, but her body - I - I've never forgiven myself. It haunts me constantly. Every second of every day. I-"

"Amy, we have to do something. Now." Rory said suddenly, pulling her to her feet and running out of the room.

The Doctor stood quickly, shouting that they couldn't do anything. It was too late.

By the time he reached the door, they'd locked themselves in the TARDIS and not even he could get in.

"Amy, Rory, come out of there! It's too late. What are you doing?"

Rory's voice, thick with emotion, replied through the door. "I don't know yet. But we have to do something. She's out there, right now. There's a lot more at stake than just her life, Doctor. I'm sorry you can't come."

The TARDIS began to groan.

"No! Rory don't! Amy! You can't change what happened! Come back!"

He was shouting to empty air. They were gone.

He cursed and resisted the tears. He was stuck here while his wife was dying and his best friends were doing who knows what. What if they were hurt? He couldn't handle that.

The Doctor stormed back into the house, not sure what to do with himself. He began to pace the entire area of the ground floor. Kitchen, front room, dining room, den, living room, entryway, hall...It was the only thing he could do.

"What exactly are we going to do?" Amy asked, still trying to keep from crying. "River's going to die and we can't change that. She has to die to save the Doctor in the past to save his future. All those things he's done since then will be erased. We would never have met him."

Rory paced around the console.

"I'm not sure. The TARDIS locked the Doctor out and flew away with us inside, so there must be something we can do."

"He never told us exactly HOW she died, did he?" Amy said, suddenly lighting up. "But he said he saved her to some sort of data core or something?"

"Yeah, so?"

Amy walked to the scanner.

"Alright, sexy. We need your help. Can you show us how River dies?" she choked, partially hoping nothing would happen.

The screen flickered and they saw River sitting on a chair, strapped to some sort of routing device. There was a countdown on the screen and she was crying. As the clock reached zero, she plugged the cables together and there was a blinding light. It was so bright that even just watching the video footage, they had to turn away.

The screen went black again.

Shocked into silence, Rory and Amy stood with their mouths open. River Song was the bravest person in all of time and space. She'd done it to save 4022 people. She'd done it to save the Doctor. She'd done it to save the universe.

Amy came to herself first and said, "Erm...Thanks, old girl. Could we see what exactly is in the data core? Like is it just black or something?"

The screen flickered again and there was a quaint little village on the shores of a lake. Children played in the parks and people laughed and seemed to be quite happy.

"Rory..." Amy said, slowly, "What if..."

He knew what she was thinking.

"But that's brilliant! Are you absolutely sure, though?"

"Yes. Let's bring our baby girl home safely."
