In Every Way Possible

If there's anything that Dean Winchester knew for certain it was that angels don't exist, and nobody should hold any sort of faith in God, even if He really was out there living it up on some golden cloud. He had more faith in his father than he ever could have had in God. And then he meets Castiel; weird, dorky, socially inept Castiel, and Dean's life takes a confusing turn in every direction. He's left to find all the missing parts of himself, and just as soon as he thinks he's got everything figured out, Castiel has to go and tell Dean the secret of the millennium. Dean doesn't know what the Hell to do after being exposed to that.
