It has been 1 week, 5 days and 3 hours since the angels started to fall.

Castiel lay in bed, Dean's pyjamas which he'd found lying on his bed feeling too oppressing on his skin. The more he tossed, the more he sweated, and the more the cloth stuck to him. The duvet also infuriated him. He tried having it pulled over his body, but that was far too hot. He pushed it down to the end of the bed, but he couldn't sleep with the chill that crept over him. The sheets felt too cool and unwelcoming, and no matter how much he shuffled, he couldn't sleep.

Cas slid off the bed. He pulled the damp top off his torso and stretched, marvelling at how the moving of your muscles actually felt nice. He stumbled to the door, knocking his hip into the corner of a chest of drawers as he went. It was a sudden, blinding pain and he let out a slight yelp. It soon wore off and he was embarrassed at his outburst. He pushed open the door, not entirely sure where he was going. He considered getting a drink. Maybe he could find a book.

As he made his way down the corridor, he heard a door opening.

"Cas? Is that you?"

Dean's voice was thick with sleep. Cas turned, not really able to make him out as more than a black silhouette in the darkness.

"Is it morning already?" He could hear Dean stepping out into the corridor.

"No, I couldn't sleep."

"I heard something…was that you?"

"I knocked into the dresser."

"Oh…" Dean seemed to be waking up a bit.

"Sorry for waking you."

"No, s'alright…why can't you sleep?"

"The bed was uncomfortable."

Dean went silent for a few seconds, then, very quietly, said "There's room in mine."

Castiel wasn't sure why he did it, but he quickly stepped towards Dean and followed him into his room. Dean turned on a lamp and they both winced at the brightness. "Do you, uh, have a side?"

"A what?" Cas frowned.

"A side of the bed."

"This is your bed, I don't own any part of it."

Dean chuckled. "Alright, well, I sleep in the middle."

"Okay." Cas wasn't sure why he was being told this. Dean sat down at the edge of the bed, and he looked over at Cas. Cas noticed his eyes strayed on his bare torso.

"Is it about the angels? Are you having bad dreams?"

Castiel didn't answer straight away. He sat not-quite next to Dean. "I don't want to talk about it, Dean."

"Cas, sometimes we can only sort things out if we talk about them."

"There's nothing to sort out. I'm tired, Dean." Cas hated the feeling that squirmed in his stomach as he knew he was lying to Dean.

"Okay, Cas. Good night."

The light went out. Cas felt the bed depress as Dean lay down. Castiel sat staring at his hands for a while, then shuffled back and lay beside him. He wondered if Dean was still awake and if he thought this was too close. He shifted sideways slightly, away from him. Closing his eyes, he thought how much nicer this felt. Even the duvet, pulled up over his shoulders, didn't bother him. And the bed didn't feel cold.

Dean opened his eyes groggily. He felt he hadn't slept long enough, but something had woken him up. He stretched out and froze. His leg brushed against something soft and he suddenly noticed the arms curled around him. What scared him most was that he liked it. And his body liked it too. He felt the hardness in the region below his stomach. He knew exactly who that was pressed up behind him and he had no idea how he was supposed to respond to this.

He knew it was too early to be awake. He closed his eyes to fall asleep, but not before laying his hand over the one on his chest.

Castiel's body slumped forward. He felt the blood trickling, warm and thick, down his back. "Please, stop…" He gasped.

"I don't think so." He had no idea who the voice was. But before he could think, he was writhing in agony.

He saw another feather flutter onto the bloody heap at his feet. He was being flayed and torn in two as his wings were ripped from his body.

"Without your wings, you're just a human. A mortal. Castiel."

Castiel could see only red. It burned in his eyelids. He thrashed and screamed, his skin shredding apart.

"Castiel."

"Cas."

"Cas!"

Cas's eyes were flying open and he was looking up into a pair of bright green ones.

"Cas, what the hell happened?"

"My wings. They took my wings."

Dean's mouth hung slightly open and he was breathing heavily, staring down at the fallen angel. "Do you know where you are, Cas?"

Cas nodded. "I'm in the bunker."

"Do you know…what you are?"

Cas paused, then nodded again. "I'm a human."

Dean sighed and Cas felt his breath tickle his face. "You had a nightmare, Cas. But no one's going to hurt you here." Dean had been leaning over him and he lowered himself to lie on his side, looking at Castiel.

Cas realised how close he was and he blinked rather rapidly. He thought he should know what comes next, but his mind seemed blank. He was so close that he could see every individual freckle on Dean's nose.

There was a loud hammering on the door. Dean almost physically jumped, quickly shuffling back and getting off the bed. Cas rolled onto his back, not entirely sure what had just happened. "Dean?" A voice called from out in the corridor.

"What, Sam?"

"Do you know where Cas is, he's not in his room?"

Dean glanced over at Cas, who was watching him inquisitively. "Probably in the library."

"Alright, thanks. I made breakfast, by the way."

"Great." Dean replied unenthusiastically. He waited for the sound of footsteps then turned back to Cas.

Castiel sat up. "Why did you lie?"

Dean shrugged, not quite meeting his eye.

"He'll only come back when he doesn't find me."

Dean exhaled heavily, walking back over to the bed and sitting at the edge. "Sorry, Cas. You just…scared me this morning."

"Why?"

Dean brushed his hand over his face. Of course Cas wouldn't notice anything weird about it. "Your nightmare, y'know?"

"Oh." Cas absent-mindedly ran his hand over his back. The skin there felt bruised. He slowly got to his feet. "I'll see you at breakfast, Dean." And he left the room.

Dean looked after him, a shirt hanging limply from his hand. He was pretty sure their entire relationship had just been drastically altered.

Sam turned down the corridor, frowning. He was sure Cas wasn't a master of hide and seek, but he'd looked everywhere. He knew what the possibility was, but he didn't want to think of it. Cas seemed like he was here to stay. Sam was heading for Dean's room, wondering what he should tell his brother, when he saw a door open and Castiel himself walk out. Sam almost exclaimed with relief then he realised that it was the door to Dean's room. And that Cas wasn't wearing a shirt. Before he could be seen, Sam retreated back to the kitchen where Kevin sat waiting.

"I think we've solved our mystery." Sam said, not sure what tone it was that his voice came out in.

Kevin lay down his book, rather startled. "What?"

"I found Cas. Walking out of Dean's room."

Kevin's eyebrows travelled up his forehead. "He might have just been going in to ask something."

Sam actually grinned. "He was wearing pyjama bottoms and no top."

Kevin's mouth fell open into a round O.

That night, after almost painfully trying to avoid Cas that day, Dean was sitting on his bed. He kept thinking of how Cas had been writhing in what looked like agony. He didn't want to imagine the horror of his nightmares.

It was for this reason, or so he told himself, that knocked on Cas's door and asked him if he wanted to sleep in his bed tonight. And, for some reason, Cas agreed.

A/N: Fuck yeah, bit of Destiel action! And I'm sorry, but I just love a bit of fluff!
