Damned

S9 SPOILERS Dean Winchester, a hunter remembered as one of the greatest, now sits on the throne in Hell as king. The Mark of Cain on his arm and the black eyes that stare back at him in the mirror remind him of just how far he has fallen. When Cas finds him will he be able to save Dean as he did once before, or are there some things even an angel can't fix? *Destiel*
