Sam offered him the bed. Castiel politely refused.

Dean offered him the couch. Castiel turned him down.

"You have to sleep somewhere, Cas."

"Sam, stop pestering him. If Cas wants to sleep on the floor let him."

"Damn it, Dean, it's going to be his first night sleeping, he deserves something soft."

"You're right, Sam. It's his first night sleeping, he isn't going to notice the difference."

"He's right, Sam." Castiel's said softly. "The floor is fine."

Sam huffed in annoyance, and retrieved a pile of blankets from upstairs, making up a bed on the floor. "Good night, Cas."

"Night, Cas."

"Good night, Sam. Dean."

He tucked himself into the blankets as Sam switched off the light, and watched Dean lying on the couch until his breathing evened out. Quietly he stood up, retrieved a book of spells and went into the kitchen, to read in the moonlight. After a few hours, Cas set the book down, rubbing his eyes. His body begged him to rest, but his pride would not allow it.

"You know, you'll ruin your eyes that way."

Castiel looked up, and saw Crowley grinning back at him.

"Be gone, demon."

"Now now. That's not very nice, angel boy."

"What do you want?"

"Why do I have to want something?"

"Why else would you be here?"

"I don't know, maybe to talk to the only other supernatural being out there who doesn't want me dead."

Castiel glared.

"Fine. The only other being who can't kill me."

Crowley realized almost instantly that was the wrong thing to say. The sadness and self loathing that gripped Castiel intensified at his words.

"Look, I'm sorry, I didn't mean that."

Castiel frowned and said nothing.

Crowley studied the man before him, trying to see into his soul and find the right strings to pull. He paused. That was the wrong way to go about this if he wanted the angel to trust him. He sighed and thought up a plan. Conversation. "So tell me, what was your favorite century?"

Castiel looked up, tilting his head in the most adorable way. "What do you mean?"

Crowley smiled. "Well, like, my favorite century was…well, actually this century. Humans have come so far. It's exciting, there's never a dull moment. What's yours?"

"I don't have one."

"Come on, you've been alive for so long, you have to have a favorite something. When was the last time you were on earth?"

"Uh, the … fourteenth century."

"Oh God. That was the worst. So dull! I feel bad for you kid. What do you think about this century?"

"Why do you want to know?"

Crowley laughed. "Indulge me."

"Well, I actually haven't really seen that much of it."

"Don't give me that. There has to be some good things. Something about this place that you like"

Castiel considered this. "I suppose I like parks."

"Huh." Crowley struggled not to roll his eyes. He'd been hoping for something a bit deeper. "How fascinating."

Castiel felt something building in his chest reaching outwards. Before he could stop it, a long yawn escaped, leaving nothing but exhaustion in its wake. He shook himself, and sat up straighter.

"Why are you doing that?"

"Doing what?"

"Forcing yourself to stay awake."

Castiel scowled. "I do not wish to sleep."

"You're going to have to sleep at some time."

"No."

"Look, sleeping is not that bad. I happen to enjoy it."

That caught Castiel's attention. "You sleep?"

Crowley leaned back, grinning widely. "Oh yes."

"Why? You do not require it."

"No, but that rarely stops me. Look." He stood up and offered his hand. "Come with me."

Castiel staried at his hand for a long time.

"It's not going to bite you."

Castiel frowned at the demon, and slowly took his hand.

Crowley grinned brightly and pulled Castiel to his feet, tugging him into the living room where Dean lay sleeping.

"Shh, we don't want to wake sleeping beauty, yeah?"

Crowley pulled Cas to an old arm chair in the corner. He sat down and pulled Casteil down after him.

"What are you doing?" Castiel whispered.

Crowley arranged the angel against him and snuggled down into the chair. "Sleeping is always easier when you do it with someone else." He kissed Castiel's forehead. "Now close your eyes, and let me do the rest."

Hesitantly Castiel closed his eyes, and felt the heat of the demon beside him. Normally that would have revolted him, but all he could feel was his consciousness sinking, drifting away in comfort and warmth. He finally gave in and let the darkness claim him.

The next morning, Dean awoke to Sam shaking him hurriedly. He groaned. "What?!"

"Dude, you have to see this."

Dean sat up, rubbing his face, and looked over to the empty pile of blankets against the wall. "Where's Cas?"

Sam grinned. "Come on."

Dean followed Sam over to a corner of the room, where he saw Bobby shaking, struggling not to laugh. Then he saw them. "Oh, no way."

"I know, right?"

Dean hesitated. On the one hand, he wanted to know what Crowley had done. On the other hand… "Bobby? Get the camera."
