AU: They were complete opposites but they were two peas in a pod and always would be. Dean Winchester had no idea when he met the strange boy with the strange name for the first time how important he would become to him. It takes ten years of friendship, loss, heartbreak, and most of all love to realise how truly naive they were to believe that all they could have is friendship.

AU: It's their mutual hatred for one another that keeps them at odds but when a dare is given to Dean Winchester for Castiel he has to take it. It's all fun and games till hearts are broken and secrets are spilled for everyone to see.
