the winchester's sister

Delilah Johnson was just your average human who lived in a family with werewolves. Except for the fact that she doesn't eat human.

Also the fact that she's adopted, abused, and pissed off.

But Delilah soon finds out a major secret about herself, leading her into the world of monsters, hunters, angels, and demons.

Rule number one: Don't travel with the Winchesters.

(This takes place between the beginning of season 4 and the end of season 5.)
