The Demon Inside

Written for NaNoWriMo '14. When Castiel wrapped his arms around Dean that fateful night in the bunker, everyone believed it was over. Dean was human again. But that wasn't really the case. Dean, in fact, wasn't as cured as he, sam, and Cas thought. With the Mark bothering him more than ever, Dean will plummet into a darkness he has never experienced before. Rated for dark themes.
