Prologue: Before

Dean hasn't spoken to anyone other than his brother, Sam, in over 10 years. When he does talk to Sam, it isn't much. On his first day of 10th grade, his first year back to school in 5 years, he meets a boy. This boy wants to talk to him, but Dean just won't speak.
After a while, Dean opens up a bit. Instead of saying what he wants to tell him, he uses a pencil and paper.
The boy, Castiel, learns things about Dean and his family he thought he'd never find out.
Until something happens...

The majority of the story will be in Dean's POV, but maybe a little in Castiel's POV. I'll try to update as much as possible, whenever I get time.
