More for my witch! Mary&Sam spn AU (that exists solely in my head)
Another thing I think would be fun. (And I wish I could read a fic like that).
Sam always knew some witch stuff. Because it's impossible to be a hunter and don't know at least some practical things or related info. After all you need to do your research and undo spells and curses. And he always thought it pretty interesting.
But he haven't really gotten into it before Stanford. During his first year he was looking for a part time job and one bookstore near campus was hiring. Sam loves books so he applied for the job. Accidentally that bookstore happened to be an esoteric one. Held by a real deal grandma witch that practically adopted him on the spot. Because she clocked him as a pretty powerful witch and as a psychic immediately.
Eventually Sam learns that his mom's side of the family was a pretty known witch family. But most of them died after they fucked with some powerful demon ten years before Mary died. At least that's what is known in the community.
Sam still got together with Jessica. Dean still went to him and asked for help. Jessica still got killed by Azazel. A demon that is apparently going after the witch! side of the family. So Sam is back on the road hunting monsters with Dean same as in canon.
But. He is a witch. And a psychic. And he has to hide that side of himself from Dean. And pretend like visions is some new shit happening and not his normal. He can't tell Dean and John what he knows about Mary either. And he's understandably afraid. Because he's what the other side of his family hunts.
So I'm as always created a premise of a fic I wish was out there for me to read 😅
So if you want to write it - feel free to xD
