It was going to be a long road trip home, after a small case the team went on in Kansas. Dean, Sam, and Cas were all in the Impala, Dean in the drivers seat and Cas in shot gun. Of course normally Sam would be in shot gun, and they would of said hell no to Castiel being up front like that, but Sam had gone threw a bit of a fight with the ghost they had to deal with, and had to lay down for a rest. Dean wasn't going to take any kind of chance of Sam over working himself how he always insisted on.
Dean yawned and ran a hand down his face, completely exhausted. As they drove down the big empty road, Dean looked back to Sam and smiled, reassuring himself he was asleep. He then looked up at Cas who was slowly drifting to sleep, obviously trying his best to stay up. "Cas, go to sleep." Cas glanced up, jutting up a bit at the sudden voice. "No Dean, it would be rude to let you drive for us and have no kind of, conscious company." he said with a small smile, trying to appear more awake. "No, Cas you need your rest. Remember, you're human now and all, and you aren't exactly use to it yet." he sighed and rubbed his forehead "Just, relax and take a nap. Please." Cas sighed and nodded slowly, looking sternly at Dean "Yes, Dean. If it is what you really wish." "Yes Cas!" he replied a bit angrily and winced, noting how fragile the angel was at the moment "Just, sleep." he smiled, trying not to seem so frustrated with him. Castiel sat back and fluttered his eyes closed slowly, still not completely sure he should be leaving Dean alone like this, but if Dean wanted it, he would sleep.
It took him maybe 2 minutes to fall into a deep sleep. Dean looked over at him and smirked, quite proud of himself and even a bit for Cas. He was a really good guy, and he was good at taking orders. Well obviously he would be... Dean continued down the road, as he tensed up at the feeling of someone leaning closer to him. He looked towards Cas to see him slowly falling over in his rest, until his head had lied itself on Deans shoulder. He kept his eyes down on him as he slowed the car to be safe. He smiled to himself a little and bit his lip, admiring the ex-angels soft and kind appearance. The more he stared, the more he got, welled up, and flustered with his feelings. He tried shaking them off but it seemed every time he reassured himself that he didn't have any, feelings, for Cas, Cas would cuddle up to him more, or he would make some kind of small noise, or, just lied there peacefully...
Dean smiled and sighed "Son of a bitch." he said as it became more clear of how he felt. He came to his conclusion. It played with his mind before but he never did accept it or let it get further into detail. The moon was shining and glistening, the road was smooth, and the night was tranquil and beautiful. He knew how he felt. He knew what he wanted. Dean took one more look down at Cas and chuckled, leaning over and placing a tender kiss to his forehead. Cas shifted and smiled in his sleep, lazily flopping his arms a bit as one came around to lay on Deans. Even if he wasn't at the moment conscious, there was a returned emotion. A slight of heart showed threw his sleepy presence. It made a difference, it made Dean grin like an idiot as he turned back to the road, calmed and happy. If only he would of seen Sam in the back, half awake, looking up at the two, smiling and nodding a bit, just as content as them, but just a bit more excited and, a bit less in the little love scene he was quietly watching.
