The hunter and angel were laying on their backs, staring at sky as clouds floated by. They were perfectly content not talking, not touching- just spending time in each others' presence.

"Cas?" Dean asked

"What? What's wrong." Castiel turned his head and scanned the hunters face for hurt. His eyes were closed.

"Nothing... nothing." He waited "What's Heaven like?"

Cas didn't seem shocked by this question.

"Dean..." The angel sighed "I'm not supposed to tell you, you know that."

"I know. I just... I'm worried. One of these days... I'm not going to live forever, Cas. Not like you."

Dean's eyes were open now, and they had tears in them. Castiel leaned over and gently kissed the tears away.

"You can't be with me forever, Cas."

"You'll never be alone, Dean. I'll follow you to Heaven. I'm not going to leave you."

"What if I don't go to Heaven?"

"You will."

"What if, Cas! What if I don't!"

"I'll follow you. Heaven or otherwise. I love you."
