Authors note: Please be nice, haven't written any fic in a long while.

Tried to keep them in character as best i could. Yes i know the story line is very much like that of season four, parts are similar, but i promise it will get interesting! Also..WOOT for fanfic with Castiel and no slash! *gasp*

I plan on making this story fairly long, so please dont judge by the thrown together first chapter xD

" I thought i destroyed Lillith!" Sam shouted in disbelief.
"So did I, Sammy." Dean snapped back, obviously irritated.
"So what, suddenly she's back in the game because someone claiming to be an angel, just has it on good authority?"

Dean just rolled his eyes, convincing his brother that his return from hell was the doing of an angel had been harder than he being had suspiciously good timing for his momentary drop ins - when Sam was nowhere close.

"Wouldn't you take God's word over a demons?" A whisper of a voice questioned.
Both heads shot in the voice's direction.

"Castiel." Dean said with a straight face.

Sam looked at him with amazement, a visible glow surrounded Castiel for a moment.
"Don't you believe in angels, Sam?" Castiel asked with a mock tone.

"Please, forgive me.." he started "You of all people should understand why I'm having a hard time believing you, if you are who you say you are."

Castiel's face turned serious as he looked Sam straight in the eyes, almost piercing his soul. "Our kind hasn't walked the earth in over two millenia, so now that we're here - it's for a good reason. I cannot tell you where to place your faith, Sam, but if this world is worth fighting for than you should really hear me out."

Sam clenched his jaw harshly but remained listening to the angel before him.
Castiel paced the room while he explained.
"As I've already informed Dean, Lillith has once more become a problem.." He locked eyes with Dean "..but she is only the..Commander, per-se, in the war the effort my brother and I have put forth to compose an alternate-fool proof- plan of action, there seems to be only two ways this can end."

"And they are..?" Dean asked Castiel's face rose to meet Deans.
"It's very plain you see, either we find the only soul capable of stopping this, or the angels and demons battle it out, using earth as the battleground."

Dean and Sam stood silent and still as stone. Dean was the first to break the silence.

"So who's this person that's apparently our one shot at shutting down our very own ultimate showdown."
He paused "They are human, right?".

Castiel replied "Yes, in a manner of speaking"
He released a heavy,tension filled breath and continued "Her name is Abigail Valentine, she escaped from a nearby mental institution not far from 's been less than twenty-four hours since anyone has seen or heard from her."

"Okay, I'm still having a hard time figuring this out, how a human girl could possibly help when even beings of a higher power are being tossed down like used kleenex." Sam stated.
Castiel once more made stony eye contact with him "Because she is not completely human, she was intended for something much greater." he paused "She has power man can only dream of, and barely comprehend. But spending 23 years on the earth as an ordinary human can cause - a kind of mental block, pushed deeper for a lack of understanding."

"So she is out there somewhere, alone, and apparently not the sanest of people, am i getting this right"
Dean asked, getting annoyed.
Castiel looked solemn as he turned his back to them "That's all we know for now. You have to find this girl."

The winchesters looked at each other as if to say C'mon! but realised that they were once more alone in the motel.
