Dean didn't have to say it. Castiel knew what Dean thought. This idea that he couldn't survive without him... He was wrong. Dean could survive. Dean didn't need him around to carry on, and to carry on with his brother, and if Castiel saved Sam for Dean then that was enough. He'd come into their lives, and he could leave them too, and one day Dean would be grateful that he had. There would be no more of this.

Maybe when this was over, he'd put his angel blade through himself, in order to keep Lucifer from hurting Dean any more.

"I haven't actually threatened to fuck your dead mother, Dean, so I'm thinking that in terms of how reasonable I am, that still leaves me right up there."

He pushed off the bed again, bringing his hand around to Dean's shoulder, gripping him tight. "Get up on the bed."
