Author's Note:Hey guys I wanted to add this little short chapter for some Cas POV, hope you enjoy it :)

Earlier that night…

Castiel waited, curled up against Dean's gradually relaxing body he listened to the heartbeat of a man he decided he'd stay with no matter what. He listened to the way it slowed down and rhythmically beat, counting the seconds through Dean's internal clock. He'd seen how exhausted Dean had been, drained colour in his face, many yawns and even slowed movements. Cas knew why it was happening, Dean wasn't sleeping well and it was because Cas kept showing him a horrible world after his eyes closed.

Dean never asked to see those things, Cas didn't want to live through it anymore than he'd shown but he couldn't be sure that he had control of it. His mind was clearing up, every day he woke up with more understanding than he had in the last. It made him feel hopeful, a little surge of excitement each time he understood a new word or could say more than a name. He could feel himself under the surface of his mind, waiting and slowly waking. Cas wanted to get to know himself again, he felt it there but getting in contact with former knowledge wasn't as simple as he would want it to be.

So instead of torturing Dean and the others, especially now that Charlie was there, Cas decided he'd sleep a little later, maybe when Dean woke up. He felt Dean sleeping; the calm and shallow breaths were as much a chorus as he needed to know. Cas stayed there for quite a while, he liked to feel Dean's chest moving and hear the little snoring noises. He was sure Dean was having a sweet dream, and while he wanted to see it he knew better than to fall asleep too.

Cas kind of understood that he'd spoken to Dean once, not in reality but in his dreams. He could sense himself, he didn't quite get the words or the feeling behind it but he knew it was there. Cas wished he could reach it but it felt so fuzzy to him now, clearer than before but still too far out of focus.

The room was dark, lit only by the moonlight through the large window. Castiel felt himself drifting, lulled by Dean's heart, his breathing matching the same gentle wave. He shook his head lightly and carefully lifted himself out of the bed. If he stayed there too long he'd fall asleep and that'd ruin pretty much everything he wanted to avoid that night.

Cas sat on the floor, perched and watching Dean sleep for what felt like ages. He didn't mind the length of time though the longer he was awake the more he wanted to sleep. The sound of muttering from down the hall caught his ears and Cas shuffled to the door to listen. He couldn't open it, the light might wake Dean which would only result in him being told to go to sleep.

"So, guess it's time to go to bed, huh?" Jet's voice was soft but Cas could still hear it clearly, he liked the tone of it though. Jet sounded less aggressive, almost timid but not quite, maybe submissive? Cas could smell them, the other was Sam and he understood immediately. He cooed softly and smiled, listening a little more intently. He knew Sam had replied but it didn't click, Cas just paid attention to the tone instead. It was tired more than anything but overall positive. Cas vaguely remembered the feeling he was getting while he eavesdropped; it kinda reminded him of watching soap operas.

The other two were quiet for a bit, their footsteps stopped near their doors and Cas quietly hoped they wouldn't go to different rooms.

"….my room?" Sam asked after an agonizing amount of time for Castiel, he was a little mad he couldn't understand the whole thing but he was sure he'd gotten the gist of it with two words.

"Please," Jet's voice was accompanied by a little, relieved laugh. Cas smiled as he listened to the two walk together into Sam's room. He stepped away from the door and went back to where he could watch Dean again.

As the time ticked away Castiel caught himself yawning several times, Dean looked so peaceful and cute that Cas just wanted to crawl back into bed and sleep again. But for the exact same reasons he refrained from doing so. He listened to the sounds of what he assumed to be Bobby waking up and wandering about, it was fairly early but the sun was peeking over the horizon so Cas figured it was okay for Bobby to be up by himself.

He sighed lightly and crawled over to the window, he looked outside at the sunlight slowly creeping into view. The colours of the sky were amazing, he found himself captivated by them and staring as they slowly changed with the passing of time. He couldn't believe how much he loved the sky; flying in the open space had been the most exhilarating thing he could remember since he'd been freed. He felt bad that Dean didn't like it, but it was nice to fly alone too. He wanted to ask Dean to fly again later, Dean wouldn't have to go with him but going outside together would be enough.

By the time Castiel realized how tired he really was the sun was higher in the sky, which was mostly just blue now. He yawned and rubbed his eyes, concentrating on keeping them open was his priority now. He'd managed to stay up this long he could go a little while more; Dean couldn't sleep forever.

Cas hummed to himself as he watched birds fly by, little tunes that came to mind though he wasn't sure of their origin. He knew that he must've heard them before, maybe before he was captured, maybe after. He didn't know, but he liked them all the same.

He was so tired that after a while time just bled together into one mess of a concept. He felt heavy but comfortable, his eyelids were strained but he held them up, and his eyes were dry from how many times he'd rubbed at them. Another yawn brought more tears to his eyes and he wiped those away just like the others, he noticed how difficult it was to lift his wings so he just let the droop behind him. The sun was so bright; it filled the room and cast long shadows onto the walls.

Cas heard a stirring sound beneath the sheets and a soft yawn coming from Dean. He looked over and smiled when he saw the man that had saved him, Dean's hair was messy and he had the cutest tired expression. Cas was glad he could give Dean a decent night's sleep, all the waiting and the exhaustion was well worth it.
