Chapter One

Dean is not getting better. The Mark of Cain has once again taken control and made him into the monster the hunter fears that he is. Once again, Dean is a demon, and he is hunting for Castiel and Sam. The angel knows he will not be able to kill Dean and that he must find him a cure. However, Cas cannot think of anything strong enough that could set Dean free of his unique ailment, but that won't stop him from trying. ***WARNING: This story includes spoilers all the way up to season 10 episode 14-this is a Destiel fic-this fic has some strong language, violence, and implications of sexual activity***
