Through the Never

2012. S8 spoilers. Cas disappeared. He was alone. And every monster he'd ever killed was somewhere in here with him. Dean's year in Purgatory started out as a struggle for survival. When he met the vampire, it became a struggle with himself. Looking for the way out, he found a kind of truth in choosing to live. Follows S8 to 8x02, then diverges. No slash.
