Night 1

Dean switched off the TV and stood up. Sam had gone to bed a little while before, but no doubt he was sat in his room on his laptop looking for a case, or researching some sort of monster to add to the blank pages of dads journal. Cas was slumped in the arm chair looking sleepy. Dean smirked at him,

"D'you even sleep last night?" He asked. Cas sat forward quickly,

"Of course I did, the day has been very tiring, that's the reason I am tired." He said sounding affronted,

"Dude, we watch films all day, you've only moved from that seat to pee. How is that tiring?" He asked laughing a little, not buying the angels story. Cas stood up and started walking to the room he had taken residence in since falling from Heaven and finding the Winchesters again. Dean followed him,

"If you're not sleeping at night, you know it find me. Your room is just next to mine just come in, I don't mind if you wake me up." Cas ignore him and pushed into his room, Dean followed,

"Dude, I'll come sit in with you till you fall asleep, whatever man." Cas turned around quickly,

"Dean, I am fine. Just go to bed." He began pushing the man from his room, "Goodnight." He said slamming the door with finality.

"I was just trying to help." Dean muttered as he walked to his room.

He changed into his pjs, brushed his teeth in the en suit bathroom, turned down the mood lights he got Sam to install until the room was almost dark, but not pitch darkness, and got into bed.

After around 3 hours of sleep, by his alarm clock, he woke up needing to pee. So he got out of bed and pattered to the bathroom, as he was washing his hands after, he decided to go and check on Cas just to make sure he was sleeping okay.

He slipped out of his room and quietly open Cas' bedroom door and slipped in. Cas was sitting, eye wide open with his back resting on the hard back of the head board staring at his toes which were stretched out in front of him. The bags under his eyes seemed to bulge out f his face and his eyes where more blood shot than they had been before Dean went to bed. Dean went and sat on the edge of Cas' bed,

"I knew you were lying." He said, a smirking covering the concern in his eyes. Cas looked at Dean,

"I don't know how to sleep... Since I - fell, I've just sat at night until I pass out, and that keeps me sane enough." Dean wiped a hand down his face.

"Why didn't you tell me?" He asked,

"I didn't want to worry you, there are all these other fallen angels wondering around and the few free days we get I didn't want to burden you with trying to help me when you deserve to rest. So I just put up with sleep deprivation." Dean sighed at Cas,

"If you had a paper cut I would drop everything and help you pull it out. You know that. What makes you think I wouldn't want to be bothered by the fact you can't sleep. You know what happened to Sam when he didn't sleep for weeks when he went crazy last year. I wouldn't want that to happen to my best friend." He clapped his hand on Cas' leg. Cas looked unsure.

"I was worried that seeing as I was the reason for all this mess, that you wouldn't want to help me with something as big as this. Plus, it's stupid isn't it, that I can't sleep." Dean chuckled,

"It's not really that stupid, you've never had to do it before, so me and Sam wouldn't expect you to know how to sleep would we? And I forgave you for that when we let you live he with us. I wouldn't have let you in if I didn't trust you, I'm a stubborn bastard." It was Cas' turn to smirk,

"I s'pose so." He said. "But still, how do you teach someone how to sleep?" He asked, looking worried that Dean wouldn't have the answers. Dean stood up and scooted Cas over so he could sit on the bed next to him. He grabbed one of the blankets that were piled neatly at the bottom of the bed and draped it over both their legs,

"Right Cas, lie down." He instructed. Cas did as he was told, "Now, get comfy. You need another blanket? Are you warm enough?" He asked, Cas shook he his indicating he needed another blanket, Dean pulled one off of the pile and draped it on top of the blanket that they were already using. Cas pulled them up to his chin and wriggled a little, obviously trying to get comfortable. When he was done he looked at Dean waiting for his next instruction,

"Right, close your eyes and relax. Slow breathing. Untense your shoulders. Try not to think. Just go with what happens, don't resist the sleepy haze." Cas smirked at Dean's use of word, but did as he was told, slowly exhaling and inhaling.

Dean stared at him until long after Cas' breathing evened out, which meant he'd fallen asleep. He watched how his eyes moved under his eyelids, how he wriggled his nose every few minutes like he needed to sneeze... Do angels even sneeze? Maybe that's another thing he'd been holding in because he didn't know how or was confuse?

After around an hour or two, Cas jolted awake. Dean squinted at the alarm clock, it was nearly 6am. Cas' eyes were wild, darting around the room, as if he were anticipating an attack. Dean looked around the room, and after gauging that there was no imminent threat, he resolved that Cas had had a nightmare, and turned to comfort his friend.

"It's fine Cas. It was a dream, just a bad dream. Nothing's coming to get you, you're safe in here. Nothing can hurt you, you'll be okay." Dean recalled, as he spoke, doing this for Sam in random motels in any and every state when his little brother woke up screaming with terror at dreams of fire and death and blood and pain. He was well practiced at calming down nightmare-induced panic attacks.

"Falling. Falling. Down. Down. Lights. Bright lights. Falling. Screaming. Shouting. Laughter. Manic laughter. Falling. Falling." Cas was muttering under his breath, his breathing still heavy. Dean used Cas' shoulders to anchor him so he could side the angels head on to his lap so that he could comfort him more directly.

"Cas, it was just a dream. They're all fine. It's all fine. Just breathe. You'll be okay." He held his hands on either side of Cas' face so he'd hold still and concentrate on Dean's face. Dean on purposely made big gestures on breathing, deliberately inhaling and exhaling audibly, encouraging Cas to do the same until he calmed down.

"It's not the okay though, they still all fell because of me. It's all my fault." He muttered.

"We'll fix it Cas, its not your fault you wanted to fix things. Metatron's a douche. It's not your fault." He paused. "On a brighter note, you managed to sleep and entire 2 hours. Your eyes look a little less puffy." He smirked at Cas hoping the change of subject would both distract him and cheer him up a little.

"I suppose so." Cas said, smiling sadly. He rolled off of Dean's lap and to the edge of the bed, where he pulled the blankets up to his ears and tried to get back to sleep for a little longer.

"Mind if I just stay and sleep?" Dean asked, trying to mask his concern with fake laziness.

"Be my guest." Cas replied rolling over to face Dean instead. Dean wriggled down and pulled the blankets up to his chin and slowly they both fell asleep.

They would be awoken by Sam bursting in at 7:30am, a look of both shock and amusement on his face.
