“Can you believe this?” Dean exclaimed furious. “That’s what? The third time he stole my baby? What is wrong with him?”
He and Sam were walking down the street and while Dean kept ranting on about how Cas was abusing his car, Sam remained rather quiet.
“What’s up with you?” Dean asked when he paused his venting for a moment.
“You didn’t go into that basement” Sam said dark.
“Why? What was there?” Dean demanded to know.
“Two men. Dead. One of them tortured and eaten by rats” Sam answered. “The other one stabbed to death”
Dean sighed and looked around to make sure no one was listening along.
“You think it’s Leviathan?” he asked Sam. Sam pulled his shoulders.
“I don’t know, Dean, but it sure as hell is something. Cas wouldn’t do that” he replied confident.
“Anna said she’d seen him cutting out letters from a man’s chest” Dean said. “What more proof do you need?”
“Then what do you suggest? Hand him over to the police?” Sam asked.
“No. We’ll find him and lock him up, until we figure out what’s gotten into him” Dean responded.
