After a year of trying to bring Heaven into some semblance of order, Castiel was done. He was tired, the kind of bone-weary, constant-aching, never-ending-exhaustion that an angelic host is just not created to withstand. The warring factions of Heaven showed no signs of reconciling, their Heavenly Father was still an “MIA asshole” (as Dean so eloquently put it), and his endless attempts to protect the human world seemed as fruitless as they were pointless.
