In which a well planned April Fool's Day prank lands everyone in the land of Ooo (Adventure Time), and Gabriel and Sam are left to watch everything unfold. Destiel and Sabriel...ZERO SHAME about the fluffy fluff

In which Castiel doesn't get to Dean Winchester in time. Dean returns to find his brother drinking demon blood, a babysitter angel, and that he has become a demon. How can he save the human race, when he isn't even human anymore? (eventual trueform!cas, destiel, and maybe even sabriel. I don't know. Whatever floats my boat)
