He woke, alone, and there was brightness around the blackout curtains he had installed when he moved in. He thought he had heard voices, but before his mind could fully wake and solve the problem, Cas walked back into the room. He was dressed again, wearing his dress pants and the button up, though he was only carrying the waistcoat and tie. He smiled at Dean, probably feeling odd having been caught leaving the morning after. Dean knew it could be awkward; he'd been there himself before.

"My employer has informed me of an emergency appointment. I need to go home and shower." Cas smiled at him, but looked down after. Dean would like to think it seemed like an inconvenience he hadn't wanted. Maybe it was? Maybe he had wanted to stay with Dean, though Dean doubted it. Who wanted to spend time with the guy that fell asleep right after sex? Granted, it had been amazing sex, so he felt he should be forgiven, even if he knew nothing about the insomnia.

Maybe the alcohol had had something to do with his confidence last night, because Cas seemed a little shy, now. He sat on the edge of the bed, pulling his shoes on, not really looking over at Dean. Dean was still groggy, but he threw the blankets off of him and found pajama pants on the floor. "I'll walk you to the door. Did you call a cab?" He stood and felt a little unsteady, but nothing he couldn't handle.

"Yes. I had to get the address from your roommate. Which, I was quite surprised to run into a man while going to find your house number. I had no idea you lived with someone." He looked accusingly at Dean, maybe unsure if Dean had slept around or something.

"He's my little brother."

Cas just looked thoughtful after the announcement, so Dean had no idea what he was thinking. The thoughts in his head were perfectly clear, though.

They walked along the hallway, Dean waving at Sam on the couch.

Cas had the best lips Dean had ever kissed. He had punched his ex-boyfriend five minutes before agreeing to come home with him. As far as Dean was concerned, Cas was worth a call. "Can I call you?" Cas looked a little surprised but nodded, and then rambled his number off when Dean returned from the kitchen with a pad of paper and a pen.

Dean yawned through the awkwardness that was Cas and him at the door. Seriously, what is the etiquette? He never knew if he was supposed to kiss these people that left his house. They had just had sex, so kissing seemed reasonable, but they were strangers, which made kissing weird. Cas made it a little easier when he shook his hand and smiled after seeing the cab pull up. "Just make sure you actually call me, Dean." Dean had smiled and then yawned again, opening his door while the cab drew away from the curb.

"Wanna watch a movie?" Sam gestured at the TV, but Dean shook his head.

"I'm going back to sleep." The look of surprise on his brothers face was enough to make him chuckle. "I don't know, man. I just feel like I still can." He knew that he never went back to sleep after someone left, but something about Cas had soothed him. Whatever the reason, Dean was going to take what he had been offered. He crawled back into his bed and fell asleep almost immediately.

He woke again and knew that he was truly awake. He'd trained himself to always look at the time years ago, so recalling the time from the night before was easy. It had been just after one in the morning when he fell asleep. The clock now said 3:45. And that little dot that said PM was on. He had just slept for fourteen hours. That was the longest he had slept since.. Well, just since.

He heard Sammy watching TV quietly in the living. He had slept through Sam coming home this morning. He had slept through dawn. He had slept more than five hours, even including the time that he had spent seeing Cas off. The TV had turned on without sending him into wakefulness. Why?

Instead of trying too hard to figure it out, he got up and brushed his teeth. He was sure the taste in his mouth must be toxic.

Sammy followed him into the kitchen and sat on the counter as Dean got himself a bowl of cereal. "Who was that?"

Dean gave him an odd look, because he never asked about his … bed partners. "Cas. Castiel, but Cas is easier."

Half the cereal was gone before Sammy interrupted him again. "When are you going to call him?"

"I'm not sure and why do you care?" Dean was a little bothered by the questions. Sammy never asked any questions about Dean's love life, not after that thing that neither wanted to ever talk about again. He ignored that thought, though. He wanted to feel happy and satisfied, not frustrated and depressed like that train of thought would make him.

"Dean, you never go to sleep again after they leave. Ever. And I heard you ask for his number." He smiled at that. It was true, he had already thought of that. Still, though, he didn't have to sound so excited. His brother wanted him in a relationship that was like his and Jess's. He wanted Dean to be happy and in love, he didn't care that Dean wasn't so sure that was really him. It hadn't worked so well before. Dean was nowhere near ready to start that process again, to place his sanity in someone else's hands.

"I haven't decided yet." He finished the cereal and set the bowl in the sink.

Sammy dropped off the counter and set a hand on Dean's shoulder. "If you don't call him today, I will."

To ignore the way that that made him feel, he just shot his brother a knowing look. "I always knew Jess was just a cover." The only reply to that statement was a bitch-face and a snort. Then, Sam went back to watch television. Dean had felt jealous. Why would he feel jealous? He was genuinely happy to see previous partners with new lovers, especially when they seemed happy. The idea of Cas with someone else had made him feel angry and possessive. He barely knew the guy, why the hell was he possessive already?

He could not let this get serious.

Dean got in the shower; because there was just enough stickiness on his body that he knew he needed it. His hands weren't shaky when he washed his body or when he dried off. His head felt blessedly pain-free. This was the type of morning he searched for all those nights he couldn't sleep. Actually feeling rested hadn't been expected, but he was very happy with it. Usually, he would have gotten five hours of sleep, maybe six, and woken up all at once and too completely when Cas left.

Deciding he shouldn't look a gift horse in the mouth, he wrapped a towel around his hips and sat on the end of his bed. His hand was curled around his phone, and in the other he held the paper with Cas's number on it. Maybe he'd just send a text.

"Hey its dean. Did ur emrgncy call wrk out?"

There. He had shown interest and an actual intent to talk to him again. Now, it was all up to Cas. He dropped his towel and started looking for clothes. He had one leg in his jeans and tripped into the bed when Carry On, My Wayward Son blared through his room. "Shit!" He grabbed the phone and answered. "Eh.. Hello?"

"Hello, Dean."
