Rating: Even thought I think K+ is better, I rated it T, just to be safe.

Ok, so this is my first fanfic ever and I'm afraid it's horrible. But, as you know, it is better to regret for something you did than something you didn't, so I decided to upload it.

Note: There is indeed a civil war raging in Heaven about who's taking over, but Castiel isn't a part of it.

Chapter 1 – Bitter

It had been almost a year they have been spending a lot of time together. Throughout all this time, from the very beginning, Meg was seeing Castiel falling a little every day. She didn't know that something like this would happen, but after she realized it, it seemed to her that it was only logical. It appeared that just by hanging around with a demon, an angel was slowly "adopting" the demon's qualities, even more in their case, that they weren't just hanging around...

Yet, his falling was happening quite fast and Meg finally was led to the conclusion, it was mainly because he didn't have the inner power that used to characterize him. He was a mess, it was easy to see. She was certain he was devastated after he found out his precious daddy didn't care about him nor anyone, for the matter. Realizing his brothers weren't any better, after Michael was locked in the cage, and started a civil war by cracking in two parts and latter in many more, didn't help either. He was broken. He had abandoned hope.

When Meg realized all these things, smiled to herself. She would totally use this... information. Since then, her conversations with him were intentionally leading to subjects that would brake him even more. She had many times stated that God was a bitch and that Lucifer should take over the world. She strongly believed that Lucifer would be kind to all those his Father had forgotten and she had never kept this belief a secret to Castiel -he knew anyway- but now, when she was stating this, she was looking deep into his eyes to make him believe it too.

All these negative feelings that were overwhelming him and having Meg brainwashing him cunningly, resulted in making Castiel, slowly and without him noticing, change beliefs.

Castiel, now broken and suspicious, didn't trust anyone anymore, not God, nor angels, not even humans. It had been a while, that the angel's fall had been noticed by the Winchesters, who had become quite skeptical towards him and Castiel someday started realizing that. He didn't say anything for some time, but he was examining really carefully their words and facial expressions when he was with them, to be certain he wasn't mistaken.

Yes, it was true. They didn't trust him anymore. When he burst and furious asked them why, what had he done to deserve this, they began charging him with accusations of weird for an angel behavior and he tried to defend himself, but in vain. They weren't accepting his reasons and were only accusing him for more. At some point, he just felt outraged. Outraged at their inability to understand him and at some of the charges that seemed completely irrational. Finally, believing his friends were ungrateful, he decided he didn't want to see them ever again and flew away.

After that day, Castiel got angry at Dean and Sam even more when he remembered that, after they caged Lucifer, they were only calling him when they were in his need. And when he appeared to help them -every time, that is- and asked them not to call him constantly as he had his own problems to face, they were blaming him for indifference and disloyalty. They never even bothered to ask him how things in heaven were, how he was.

And then the angel remembered the time Dean met him. Dean knew the one walking through that door, was the one who saved him from hell and he welcomed him by shooting and stabbing him. This memory made Castiel only angrier.

Now, it seemed to Castiel that, all this time, the only person that was always treating to him nicely was Meg and he had started thinking that maybe demons were the answer, after all.

NOTE: Sorry for the "God was a bitch" part, but after all these episodes of Supernatural, I just couldn't help it!
