Well, there you had it. Straight from the horse's mouth, as it were. Or, rather, the mouths of the guys who talked to the guy who talked to the horse. Castiel entertained -- very briefly -- that Sam and Dean might be lying to him, but he knew they had no reason to. The three of them were on the same side -- were some of the only people on that side. If nothing else, they might lie the other way, spare him the aching feeling that lodged in his chest at the very thought.
God wasn't dead. He wasn't off on some extended vacation somewhere else, unaware of what was happening. He wasn't trapped, he wasn't duped, he wasn't even not paying enough attention. God knew exactly what was happening. And he didn't care.
Castiel turned his eyes upward, knowing now that every word he spoke, every question he'd asked, every request for guidance as he fell and tried to pull himself back up had been heard, would be heard. "You son of a bitch." He understood now, every comment this Dean had made about absent fathers and disappointing fathers and dead-beat dads. Still, even Dean couldn't begin to grasp this betrayal.* "I believed in you."
No answer came. And now he knew that none ever would. He pulled the amulet he'd borrowed from Dean from his pocket. "Here. I won't be needing this, anymore."
And he turned and walked away.
The fight wasn't over. He knew that. Not by a long shot. But dammit, Castiel needed a break from it. So he took a page from Chuck's book and went to Thailand.
They had liquor stores in Thailand, right?
* shut up, Cass is totally actually an adolescent boy.
