Once upon a time, in a GoAnimate world, there were two characters, Jack and Rose. They met at a park. Jack was playing his guitar and Rose was drawn to the music. Their eyes met and it was love at first sight. They started to talk and found they had a lot in common. They went on walks, shared ice creams, and soon they were inseparable.

There is a fanfiction that I heard about where Michael teams up with Hermione to study the similarities between magic in 'Harry Potter' and the powers in 'Supernatural'.
