"You hungry, Cas?" Dean aimed his question at the angel who was sitting on the couch, staring intently at the television screen.

"I'm watching this show right now."

"You gotta eat, Cas."

"Dean, I am an angel, I do not require sustenance," he growled, which was slightly scary.

"What?" Cas was talking in long words that confused Dean a lot. The smart words didn't really match the child's body.

Sam looked up from his book. "I think it means he doesn't need food, Dean."

"But everything needs food. Everything," said Sam.

"Yeah, Cas. Sam knows loads, and he's only five. Come on," he said, holding out his half eaten burger. "Try a bit, it's delicious."

Castiel walked slowly over to Dean and took the burger. He looked at it, head tilted to the side in a way that Dean found endearing. He raised it slowly to his mouth, and took a tentative bite. Dean watched eagerly for his reaction as Cas chewed and swallowed. The smallest smile lifted the corners of his mouth as he handed the burger back to Dean. "That was… nice. Thank you, Dean."

"Here, have it." Dean pushed the wrapper into Cas' hands. He waved off the protests he knew were going to come. "Eat, Cas. I already had some." He smiled secretly as he watched his friend—because Castiel was now his only friend other than Sam—ate the rest of the burger neatly.

The angel licked his lips. "Thank you, Dean, for sharing your food with me."

"No problem, man," Dean smiled. "Hey, Cas, I can see your wings!"

The huge, black feathers had suddenly appeared behind Castiel as he'd been eating. He strained to look at them. "Seems they're controlled by feelings," he shrugged.

"Aah, cool."

They were sat on the couch watching cartoons (Castiel's choice) when the eldest Winchester felt a hand gently take hold of his. He turned sideways to look at the angel next to him, who was busy over-analysing the happenings on the TV screen. Dean would usually watch the news when Sam was asleep, to make sure his father hadn't been hurt. Or worse. He wasn't sure what he'd do if that happened. But now wasn't the time to think about it.

"Dean, I can't sleep!" Sam whined from the end bed.

His older brother grabbed the remote and turned the volume down to almost mute. "Better?"

"No," Sam shook his head, floppy hair obscuring his face. "Read me a bedtime story?"

Dean got up from the couch to join Sam. "Sure. Come on, Cas. You're welcome too," he shouted over his shoulder.

Castiel rose to join them as Dean whispered a story to Sam about dragons until the younger Winchester was fast asleep.

"You go to sleep too, Dean. I'll watch over you," said the angel.

"No, it's fine. I don't need-" he was cut off by a yawn. "Oh fine," he sighed, snuggling closer to Cas. "But if anything happens, you wake me asap, okay?"

"Yes, Dean," came the reply as he felt smooth wings wrap around him.

"Night, Cas," he whispered.

"Goodnight, Dean."
