A/N: I'm pretty sure this could count as a first chapter. I didn't write much, this is just a short wrap-up of the end of S6, so THERE ARE SPOILERS if you haven't seen the end of S6! THIS WHOLE PIECE IS ONE BIG GARGANTUAN SPOILER. DON'T SAY I DIDN'T WARN YOU.

The demon Crowley chuckled to himself after Castiel departed. His plan would work, without a doubt. By trusting the angel with millions of souls from Purgatory, he just might be able to gain an ally and stop the Apocalypse.

The idea was to split the souls from Purgatory, half for him, half for Castiel. He hoped with this power, they could prevent Raphael from destroying the earth. Not that Crowley really cared about the oh-so precious earth, he just wanted the power. He just wanted to keep Dean and Sam off his ass, so he told Castiel to keep their little deal a secret. He knew that even if Castiel gave them out, the good angel would lose the faith his friends had for him, and it would work out either way.

All he had left to do now was wait. He grinned like the evil thing he was, and returned to his humble abode in Hell.

Dean sighed, frustrated, for the umpteenth time that afternoon. "Really, why are you two gangin' up on Cas? He trusts us completely, why can't you trust him? It's not like he's working with Crowley. Crowley's a demon for cryin' out loud!" He was angry, and the slight tinge of red on his face did nothing to hide it.

"Sorry, Dean," Bobby paused mid-sentence. "I hate to be suspicious of angel boy, but something just isn't addin' up right. I find it odd that he can't help us find Crowley, but is somehow convinced he's still alive!" Sam nodded his head in agreement.

Dean shook his head and snorted in disgust. "I can't believe you," He ran a hand through his hair and finished his sentence in a near whisper, "he's our friend."

"Dean, I wanna give him the benefit of the doubt as much as you do," Sam said slowly, choosing his words carefully, "but I think we need to cover all bases here and assume the worst."

Castiel watched the argument unfold, hidden from their view. Little did they know that he had a genuine deal with Crowley. A rather risky deal, at that, dealing souls like they were currency. But, that didn't hurt the angel nearly as much as it should have, although deep in his Grace he knew it couldn't be right that he had made such a deal with the biggest con artist in Hell.

The part that bothered Castiel was Dean. Dean put so much trust in Castiel. He was so convinced that the angel wouldn't go behind their backs and work with the enemy. After all, everything he did, he did it for Dean, and that had finally gained the human's trust. But now, he lied to the human and spied on the conversations he had with his brother and Bobby. If he was found out, Castiel would lose all of the trust that he had worked so hard to gain.

Castiel disappeared. He had to prove to Dean that this was the right choice.

As soon as Dean dropped the match, Castiel knew. He knew that he had been discovered.

The small flame lit into a neat circle around the angel, trapping him within the holy fire. He was somewhat confused, at first. What had he done to reveal himself? He had used the angelic powers to keep himself hidden from the humans, but he feared that his "mojo" was not to blame here.

It was later explained that he had reused a phrase that he could not have heard from anyone other that Bobby, and when it was said, Castiel was not in the room. They knew he had spied on them, but what else did they know?

"Look me in the eyes, man, and tell me you're not working with Crowley!" Dean's gaze penetrated Castiel, and would have stared into his very Grace if it could.

Castiel certainly tried, but he could not lie to Dean, and his gaze shifted to the floor.

A look of pure hurt flashed in Dean's eyes, and Castiel would never forget that. He would never forget how much that one look told about what he had done. There was no way to go back now, for the trust had been shattered, and it would never return completely.

Castiel asked several times for an explanation. He just wanted for them to hear him out and understand from his perspective. He tried his best to explain to the humans what he planned on doing and why, but they wouldn't have any of it. Even Sam told him there was no way they could trust him. Not after what he had done. "You wouldn't understand. It's complicated." Castiel gave up trying to explain. It was evident they wouldn't listen, so why bother?

"When crap like this comes up, we deal with it. We don't go out and make a deal with the devil." Dean explained the whole situation in an entire sentence, making Castiel feel a slight twinge of guilt.

"You make it sound so simple when you say it like that. Where were you when I needed to hear it?" Castiel mumbled, his low voice faltering.

"I was there. Where were you?" Dean's facial expression coupled with the words he spoke made the guilt even worse. It was all Castiel's fault that Dean could never live the apple-pie life he wanted. All of that was ruined because of him.

It was unfortunate that he could not back out of the deal, because if he could, he sure would have. However, he had to carry on with his plan. Not even distrust from the humans would stop him now; he had to prove to the humans that he, an angel of the Lord, knew what he was doing better than they did.

He could then hear Crowley's minions coming to aide him. Castiel did what he could to save his friends from the demons and told them to run for their life.

And so, after the gates of Purgatory had been ripped open, after a few complications, and the souls were ingested, Castiel sought out Raphael. It was time to stop the madness in Heaven with the power of millions of souls.

With a snap of his fingers, he used his godly powers to eliminate Raphael for once and for all, causing him to explode on command. He turned to away from Dean, yet spoke to him pointedly. "So you see. I saved you." He looked at the large blood stain on the walls and floor that had once been his deceptive brother.

"You sure did, Cas. Thank you." Dean spoke with haste.

"You doubted me. Fought against me. But I was right all along." Castiel turned toward Dean and Bobby as he said this, a small, rare smile on his face that felt completely different than usual.

"Yeah, Cas, you were. We're sorry." again Dean's response was nearly immediate, as if to not offend Castiel. He then tried to convince Castiel to put the souls back into Purgatory, where they belonged? But they belonged with Castiel. He worked so hard for this new power, he wasn't going to let it go this early in the game, and not just to anyone. He was cut out for this. It was his destiny.

"We were family once," Dean paused and swallowed for a brief moment, "Please. I've lost Lisa, I've lost Ben, and now, I've lost Sam. Don't make me lose you too." His breathing quickened. "You don't need this kind of juice, Cas! So get rid of it before it kills us all!"

If Castiel were still an angel, he would have given up at that point. But he was no longer that weak, naïve thing. "You're just saying that because I've won. Because you're afraid." He strode languidly toward Dean. "You're not my family, Dean. I have no family."

He barely felt it when Sam stabbed him from behind with Raphael's blade. As if such a petty weapon could kill a god! He removed the blade lazily and gave it a smug look. "I'm glad you made it, Sam," He nodded at the new presence, "but the angel way won't work. Because I'm not an angel anymore."

The look on Dean's face as Castiel, no longer an angel, approached him, made the next sentence somewhat difficult to say.

"I'm not an angel anymore. I'm your new God, a better one." He spoke to all three men, but concentrated on Dean as he spoke. "So, you will bow down, and profess your love unto me, your Lord, or I shall destroy you." Castiel admired his new tone of voice as he said this. He was no longer the awkward and unsure angel. He was a God now, filled to the brim with power, and Dean had no place to deny him.

Dean swallowed loudly, the dry click echoing through the room, before ducking his head and answering Castiel in a strong, sure voice.

"No."

A/N: So, what do you think? I'm sure there are 4,513,456 other stories with this same plotline, but I wanted to write my own.. Part two coming up soon, I'm planning for three parts. And I sure hope I got all of the quotes right, my computer speakers crapped out on me and it was difficult for me to hear what they were saying.
