To Hell and Back

Destiel Slight AU. Dean's back from Hell and he's fine, he has to be and he's been telling them all that for years. But when he goes to bed at night he's not fine and nobody knows it. Until one day, Castiel drops in while Dean's asleep. So while the show must go on, and the boys must keep fighting, Sam wasn't the only one wrestling Hell in his head. NO COPYRIGHT INTENDED.
