I'm only on season 9, if I get any of the lore wrong I am so sorry. Jasmine is a normal girl, she goes to high school, she has a few good friends, she hates homework, Fire is her soulmate, alright maybe the last one isn't normal but when has anything EVER been normal when it comes to Jasmine, being kidnapped at 11 by demons and being forced to fight other physic children isn't exactly a normal activity for a almost teen. Never mind the fact that she'll become immortal when she turns 21. Even though she has all that working against her Jasmine tries her best to be normal but when one of her best friends is killed and she finds out it wasn't exactly a normal, non-paranormal murder she decides to call the only people she knows that can deal with this, Sam and Dean Winchester.
