Paradox [HP & SPN crossover]

Dean Winchester has always been an enigma. He has also always been a saviour. There are a lot of things he hates but if you ask Sam, his answer is always the same.
Dean hates witches.
A lot of people know Dean as different people.
Sam thinks he is his stupid, caring, soldier brother without a mind.
Anna, their sister thinks of him as her lifeline, her everything.
Hogwarts knows him to be smart, cunning, kind and brave.
Castiel knows him only as Dean.

So when the hunting community, Hogwarts, along with all the creatures the Winchesters have encounter appear in the same room to see the Winchester's lives, they are in for a surprise.
