Ghost's of Hell By: _DevilsDue_

Dean and Sam are brothers, they mostly grew up with Bobby because there dad always went away and just dropped them of there. One day Bobby finds a little girl named Toby. He adopts her and John (Dean and Sam's dad) thinks he can't take care of her.
Now Dean and Sam and Toby are all grown up, they hunt together, they go back to Bobby's place to see Dean and Sam's dad is there. He asks them to go on a hunt, Dean and Toby are really close. They soon date, They continue on there life's with hell, heaven, demons, Angels (in this story they met Cas already) they meet up with Castiel but John and Bobby have no clue they met him. One day a human sells Toby's soul not his own. She's dragged to hell (exactly how Dean went to hell) for 5 years (50 years in hell) and Dean, Sam, John and Bobby try to find who had her soul. She returns somehow and she's a little different. (Like she's a demon, I made it so John dies differently, he doesn't go to hell) When John and Bobby meet Castiel, they tell there children to tell them who he is. They explain. They, soon turn Toby back human but that'll take a while. John and Bobby both die from leviathans. Sam, Dean and Toby have no clue on how to live anymore. Castiel was dating Toby but he had to leave, they lasted 2 weeks, after he left she fell for Dean. Toby is blonde and she has amazing rare blue eyes.
