Dean and Sam Winchester have a younger sister, Ashlee, and by younger, I mean she is 14 years old. Told you, younger! Anyway, the guys discovered they had a sister after their father, John, died. She called them, crying, about how her mum was murdered by a human with black eyes. Naturally, Dean and Sam were skeptical about Ashlee and her story but when they met her, she looked a lot like Sam and Dean. (Photo beside text; imagine she looks like a 14 year old and has Dean's eyes). They did a follow up of her background and her birth certificate and in the Father section it says, 'John Winchester'. While they were there, they banished the demon to hell. She started off on her journey with them.
~Startingoff at the start of Season 4 when Dean returns~
Imagine Sam and Dean's mother had not died when Sam was an infant. but instead died when Alexandria, their sister, was just 6 months old.
she was 6 years younger than Sam and 10 younger than Dean. she was born blind but John only found out when she was 3. image being a blind hunter.
Alex fights everything from witches, vampires, and Wendigo's to demons and Dean.
Will she stop the end of the world before it happens? Or will she be the cause of it?
This is not going by the show so the big happenings are way out of order meaning the apocalypse will happen after they get the bunker, the angels falling will be before the apocalypse or stuff like that.
