A/N: I love sister fics…the show could really use some women hunters and I don't trust the Campbell cousins….but I was thinking about this story for a while after we found out that Mary was a hunter. What if in-between Dean and Sam there was a sister, one named Grace and instead of being raised with the Winchesters she was raised by John's brother-in-law Jacob and his family….

November 2nd,1983-

"Let's say goodnight to your brother," says Mary.

She was holding her eldest son who was almost five years old, behind her being carried in by her husband was her middle daughter Grace. Dean and Grace looked exactly alike with their light hair, the line of freckles on their face and their light eyes. They were just a little more than a year apart Dean being born January 24th and Grace being born February 1st of 1980.

Mary and John lifted up their young children so they can kiss their younger brother goodnight.

"Goodnight love," says Mary kissing Sam's forehead.

"Night Sam," says John ruffling the boy's hair.

Mary and John turn to their young children John wraps his arms around Dean.

"Night buddy," says John kissing his blonde hair.

Mary kisses Grace before picking her up and smiling at John who gave her a quick kiss on the lips.

"I got Gracie you got Dean?" asks Mary.

"I got him," says John and he turns off the lights, "sweet dreams Sam,"

SPNSPNSPNSPN-

Grace tiptoes out of her bed and into the hallway.

"Daddy?" she asks staring into the nursery.

"Shhh," the figure mutters and she continues walking, nearly into her mother.

"Gracie what are you doing up?" asks Mary rubbing her eyes.

"Going potty," she replied walking into the bathroom.

SPNSPNSPN-

"NO! MARY!" cried out John and Grace runs out of the bathroom.

Fire erupts in the nursery, and Grace places her hands over her face protecting herself.

"Daddy!" cries out Dean just as John runs out with a crying bundle.

"Take your brother outside as fast as you can, don't look back now Dean go!" cried out John, "Go Grace!"

Grace doesn't move she stares at her father whose running into the nursery, she goes to run forward when a piece of the door falls on her.

"NO! MARY!" cried out John before turning on his heels and only to be greeted by his daughter's body, "c'mon baby girl,"

He lifts the piece of wood off of his daughter before picking her up and running down the steps.
