Sams heart sunk, literally. He'd just finished reading the Professors research and now he knew everything.

And it wasn't good.

For the briefest second, he didn't want to tell Dean. Hell, he wished he hadn't read it, that he could forget it. But he couldn't, and Dean had to know.

"Dean, we gotta talk"

"Nothing good ever comes after that Sammy, ever. It's that bad huh?"

Sam knew it was, but he couldn't bring himself to say it. So he went straight into explaining mode.

"So this symbol " He began, pointing to the one that the demon had scratched around "depicts what we have now, gates of Hell open, demons free to come and go as they please and Angels with no Heaven to go to."

"Well no wonder he wants that." Dean replied, thinking back to what Celeste had said earlier. "But why did he want us to figure out the other symbol…. that means we can stop it? That's gotta be the last thing he wants? It doesn't make sense"

"Because of this" Sammy replied, pointing to a paragraph of text below the symbol illustrating balance.

"The balance shall be restored by the redeemer, the human loved by the fallen whose love, and life must be willingly sacrificed to restore the balance"

"He wanted us to know that the only way we can get rid of him, is by killing Celeste? That Son of a Bitch! He was playin' us this whole time! He wanted us to know that we can't stop it, that this is how It ends!" Dean shouted angrily.

"And he wanted us to find out in this timeline, because she hasn't been born yet. He's rubbing it in our face Dean. We're screwed."

"If she lives, the world is screwed. If she dies, the balance is restored….How can that be right? I cannot pick between my own kid and the fate of the world, I wont! I'm tired of choosing Sammy, between my own blood and the friggin world!"

"It's not your choice" She began.

They turned around to find her standing In the doorway.

"Whatever you heard, forget it" Dean spoke, getting up to grab himself a whisky.

"Forget it? Forget that my death is key to putting the world back together? Tell me, how the hell am I meant to forget that!"

"I recommend this" He replied, pushing a glass of Whisky toward her, which she promptly downed.

"Wow. Like Father like Daughter" Sam replied, pouring himself a shot.

As she lined herself up another shot, they both gave her a look.

"Yeah so I just found out I have to die, I need Whisky" she replied, grabbing the decanter and heading back to her room. Dean began to follow but was abruptly halted by Sam.

"Leave it Dean."

Dean wanted to protest with a quick witted comeback, before realising Sam was right. He should give her time to process. He grabbed the other decanter and promptly sat himself down on the couch. Whisky in large quantities did the job for most of the shit he needed to forget, but now, it was barely affecting him.

"Is that a bottle of Whisky?" Cas questioned as she re-entered the room.

"Yep. Just found out that I have to die to put the world back together and that if I don't, things are going to get seriously out of hand"

"There must be another way"

"No, this is it Cas. The Professors research was pretty clear. I have to sacrifice my love for you…"

She paused.

She hadn't meant to say that, out loud.

"You love me?" He asked in his perfectly sincere way.

What the Hell, she was going to die anyway.

"Yes. I know It's been like a week or whatever but it's just like it was when we met in my time Cas, I couldn't help myself then and I can't now. I love you"

"I love you too Celeste. I can't explain it, but I do. My love for you is the only part of my humanity that is clear to me."

As she looked at him, she realised she couldn't imagine life without him. Life without running her fingers through his perfect bed head hair, life without looking into his inky blue eyes. Life without that adorable look he had when he didn't quite get something. But she knew that was the future.

Life without him.

Life without Dean and Sam.

Death.

There was only one thing that she wanted now.

She placed her arms around his neck, drawing him to her. She kissed him long and hard, making sure to remember everything- the softness of his lips, the way he tasted. She let her hands wonder to his shoulders, where she began removing his coat. He pulled away for the briefest second, unsure this was the right thing, but quickly gave in to his newly human desires. She wanted to be gentle, it was technically his first time but she found she couldn't hold back.

As she climaxed, she swore never to forget this moment of pure happiness with her fallen angel.

She wished she could snuggle down and spend the night here, sleeping in his arms but she knew she couldn't. She waited, until she felt that familiar gentle breath on the back of her neck which she knew meant he was sound asleep. Then she waited for the closing of the boys bedroom doors.

Confident that everyone was now asleep, she crept slowly out of the room, closing the door as softly as she could.

She walked down the hall and through the main living area to the front door, again closing it as softly as possible.

It was a humid night, she felt positively warm in her short silk nightdress as she walked down the road, angel blade in hand. She felt an odd calmness from her decision. She was in control now. This was her choice.

She stopped.

This seemed as good a place as any to die.

She twirled the blade in her hands for a minute. She wouldn't wimp out. She had to do this. Her life had to be given up. It was time.

As the blade entered her, the world became a very different place.

The sky above seemed to be racing, whilst the ground stayed perfectly still. She could feel the warm blood pouring down her front, over her hands which were instinctively over the wound. Not that that would help, she was fated to die here, alone. For just a second, the sky shone bright and she knew Heaven had been restored. She then caught the briefest glimpse of the dark shadow made up of millions of twisted souls, all being driven underground where they belonged.

"It….worked" She mumbled.

"Indeed it did" Spoke another voice.

She looked up.

"Death" She spoke.

"Had to make this a personal visit, you being the redeemer and all."

She looked at him, unsure what to say in response.

"You gave it all up- your love for that bloody fallen angel, your life. The worlds back in order, but you… you got the raw end of the deal."

"I don't know, I hear Heavens nice this time of year." She replied.

"Humour as a tool of deflection, just like your father"

"I'm kind of dying here, shouldn't we be going…?"

"Eager aren't we?"

"It's inevitable"

"I disagree"

"If I live, the world goes back to being screwed"

"No. You died to save it. Going back doesn't undo that"

"But I'm supposed to die!"

"And they call me morbid. Yes, that's what was written but Death is my domain and I'm not ready for you yet Celeste."

"But Cas, he'll be in Heaven. I don't want to go back if he's not there!"

But it was too late.

"Celeste! Celeste!"

As she opened her eyes, she was met with the bright unflattering glare of a hospital room.

"Thank God, I thought you were dead. I can't believe you did that, what were you thinking?" Dean replied angrily.

"Cas, where's Cas?"

Sam and Dean looked at each other.

"He's gone. They're all gone…..as far as we can tell"

She felt like she couldn't breathe.

"Death you bastard!" She screamed. "You should have let me die!"

"You don't mean that" Dean spoke.

"You don't get it- I love him Dean! I've loved him since the day I met him and I don't want a life without him because it's not a life!" She replied, tears running down her face.

"I think It would be best if you were to both leave" A nurse spoke, over hearing the commotion.

"Come on Dean" Sam said, ushering him outside.

As the door closed, she turned to face the window. It was a beautiful, sunny day to the rest of the world but to her, it was a dark day. She knew she had done the right thing, but nothing could have prepared her for the emptiness she would feel, knowing she'd never see him again. She cried for hours, until she couldn't cry another tear. Finally, she fell asleep through sheer exhaustion.
