John still wasn't back, and it had been ten days. However, the trio of boys looked after each other – Castiel got food, Dean was on guard duty and Sam was just Sam.; a little kid, young and innocent, and really smart.
"Hey Cas," Sam called to the angel, looking up from his book for signs of a tan trenchcoat. "What's Heaven like?"
Castiel turned to look at him, brow furrowed in concentration. Dean turned to study him too. "Heaven is…" Castiel began, before faltering. "Heaven is… What is Heaven?" he murmured to himself. Suddenly brightening, he readdressed Sam.
"Heaven is home. It is large, and spacey, and beautiful. Heaven is a place of light, full of good people."
"And the angels?" Sam asked, entranced.
"The angels are creatures of beauty. They keep the peace and calmness of Heaven and their grace fills the air. Their wings are made of the finest feathers, and they are all beautiful." Castiel sat there, caught up in his own vision. Dean looked at him.
"Do you miss it?" he asked.
Cas turned to him. "I do. But I am here on Earth for a reason. And if I had not come here, I would not have met you. I'm happy I did."
Dean clasped him on the shoulder, and smiled. "I'm glad you came here too, Cas."
After Sam had gone to sleep, and they had checked the news, Cas and Dean stayed up, talking.
"How old are you?" Dean was eager to know.
"Very old," was all Castiel said on the subject, deciding instead to steer the conversation in the direction of how amazingly clever Sam was.
Dean beamed with pride as he looked over at the sleeping pile on the other bed that was his baby brother. "Sam's a genius," he said.
"He is very clever. Destined for…" Castiel quietened.
Dean looked concerned. "Destined for what, Cas? What were you gonna say?"
"Nothing. I have said too much."
"What do you know that I don't?"
"I know a lot of things you don't, Dean," growled the angel. Dean backed away slightly, and Cas' expression softened. "I'm sorry. I am not allowed to tell you things like that."
"I get it Cas," Dean whispered, wrapping his arms around the other boy and breathing in the smell of the trenchcoat he had got used to. "Can I still sleep in your wings tonight?"
Cas seemed confused by the idea of Dean not sleeping in his wings. "Yes, of course." He pulled away and checked the door was locked and bolted before going to sit on the edge of Dean's bed. He looked over at the other boy expectantly. "Are you not joining me?"
"Yeah sure. Just let me see this clip of news," said Dean, focused on the television.
After a while, he shrugged it off and joined Cas, and the two lay in bed next to one another. At some point in the night, Castiel wrapped his hand around Dean's comfortingly, but Dean was already asleep.
