Hey, guys. Since my last oneshot seemed to work out pretty well, I decided I'd write a proper fic. I don't know how long it'll be and stuff, basically I'm just making stuff up as I go along. First chapter is always rather short, because I want to know what everyone thinks before I continue. So please, leave reviews, tell me what you think so I know whether or not I should go on with the fic! It's very very much appreciated.

"Damn it, Cas!"

Dean quickly swallowed the rest of his rant as the angel whom had just appeared in front of him, collapsed on the spot.

"What the-"

"Dean.."

The hunter kneeled down next to the angel, grabbing his shoulders in a fit of panic. "Cas, what the hell is going on? Say something!"

There was blood dripping out of Castiel's nose, and blood oozing from the middle of his chest. His coat and shirt were completely stained. There was a faint sheen of sweat on Cas' forehead.

He looked up at Dean in a daze.

"That's it," Dean muttered.

He scooped Cas up, the only reason he could do this being that the angel was apparently drained of mojo, and lay him gently on his motel bed. Cas groaned, closing his eyes. Suddenly, Dean felt himself being thrown backwards, smacking against the wall with a thud. The light-bulbs cracked and shattered, leaving the room in total darkness. Dean blinked, his eyes quickly adjusting to the dark, when there was a flash, making the hunter cover up his eyes. When the white light behind his hands had faded, he slowly lowered them. What he saw took his breath away.

Castiel was still lying on the bed with his eyes closed, but a light was surrounding him. Long, dark shadows were stretched over the bed and the floor, until Dean realised they weren't shadows. They were Cas' wings. The first thing Dean noticed was how huge they were. They filled almost half the room. The second thing Dean noticed was how beautiful they were. Hundreds of shiny, black-blue feathers, fluffier at the base and growing more slim and long at the tips. The light surrounding Cas reflected slightly on the wings, causing them to shimmer.

Dean couldn't stop staring, his jaw on the ground. He noticed the feathers were slightly ruffled, and suddenly he wanted nothing more than to walk over, run his hands gently over them and straighten them. He was too shocked to even move, though. The wings gave a tiny flutter, causing Dean to jump, and then they disappeared again. The room was pitch black, with the hunter still pressed against the wall, his mouth gaping.

That's how Sam found him when he walked inside the door.

"Dude, I've got the grub-" he stopped mid-sentence. "What the fuck?!"

He ran over to Dean, not having spotted Cas yet. He pulled his trembling brother up, checking him to make sure he was okay.

"Dean, are you all right?" he demanded.

"Y-yeah, I'm fine," Dean muttered, absent-mindedly pushing Sam away.

"What are you doing?" Sam asked, bewildered.

"You got a flash-light or something?"

Sam nodded, reaching into his pockets and pulling out a torch. "What's going on, man?"

Dean shook his head, taking the torch. "I have no freakin' clue."

He shone the light onto his bed, heaving a huge sigh of relief when Cas was still lying there, his eyes closed.

"Holy crap! What happened to him?"

"I don't know, Sammy. He just appeared and then.. he collapsed," Dean exclaimed, running a hand through his hair as he stared at the angel.

Sam leaned forward, lifting Cas' shirt up to reveal the gaping hole in his chest. "Jesus Christ," he muttered.

"Sammy, he's gonna be okay, right?" Dean asked desperately.

Sam swallowed. "What happened that made all the lights go out?"

Dean didn't reply for a while. "I.. I'm not sure. The room lit up, I think it was his Grace."

He wasn't sure what had made him keep quiet about the wing part, but he was glad he hadn't blabbed.

"Okay. First, we need to get some light in here. I'll go down and tell the receptionist that our power's gone or something, and get some candles or whatever. Don't move," Sam ordered, and he left.

When Sam had left, Dean leaned over the angel, searching his face.

"Cas? Can you hear me, man?"

Nothing. Not even a twitch.

"Castiel, I fucking swear, if you die on me I'm going.. I'm gonna.." Dean didn't know how to finish his sentence, so he didn't.

Cas' eyelids fluttered, and the hunter laughed in relief. "Cas!"

"I'm not going to die, Dean," the angel murmured. "I need to rest and heal."

"Sure, 'course.. uhh.. anything we can do?"

"No," Cas answered shortly, before closing his eyes again.

Dean stared at him for a while. "Right. Yeah. Okay."

A few moments later Sam returned with a couple of lightbulbs, replacing the shattered remains of the old ones and switching the lights back on.

"Cas says he's all right. He just needs to rest and heal."

Sam frowned. "When the hell did he say that?"

"Just now. Look, Sam, I don't know 'bout you, but I could use a good night's sleep right now. I've had enough weirdness for one night," Dean exclaimed, glancing at Cas.

"Yeah. Tomorrow we can find out what the fuck happened to Cas. Right now, we all just need to rest," Sam agreed.

Dean grabbed extra blankets from under the bed, and made his way to the couch. They both threw a last, worried glance at Castiel before switching the light off and trying to fall asleep.
