Like my other Supernatural oneshots, this one is short. I don't usually go for slash, even onesided, in this fandom but I was rewatching the sixth season and I just couldn't help it. This is set in the fifth season, though.

I might write a longer Dean/Cas story. I'm not sure yet…I wanted to try out this little oneshot first…

I don't own Supernatural

Dean was leaning forward in the chair, elbows on his knees, glass of cheap booze in hand and his eyes trained on the bed, on the angel sleeping on it. He hadn't moved since Sam had fallen asleep in the other twin bed on the other side of the room.

He'd done this before, too many times to count, for his brother. He should be used to it. The whole sitting vigil thing. This time was different. Sam was sleeping soundly and it wasn't the sleep of the injured.

This…this was unnatural and unsettling. Cas was still on the bed but it wasn't the stillness that bothered Dean. Cas had that down when he was awake and healthy. He could be that…completely still and patient. It was a skill that Dean had never mastered himself.

No, it was the sleeping part that bothered him and the blood that had ran from Cas' nose before he'd passed out. It was the fact that he had passed out in the first place. It was all just…unsettling.

It knocked the breath out of Dean, seeing Cas stumble, having to catch the angel before he fell on his face. It stopped his breath the same way it did when Sam or Bobby got hurt. He'd been terrified, horrified that this was it…again.

Cas had already died once to help him. He still remembered that feeling. When they'd been zapped into that plane, when they'd gone to see Chuck and found out…

There was a pretty good chance they would all be dead soon. Even if they somehow managed to avert the apocalypse they'd most likely all die in the attempt. He knew it. In fact, he always knew it was a possibility. He could die tomorrow on some random hunt. The knowledge should have made him more open but he just wasn't built that way.

Dean knew himself well enough to know that what he was feeling was not something brotherly. He knew himself well enough to recognize it those types of feelings even if he hardly ever felt them for anyone.

It wasn't that Cas was a guy. That wasn't what kept him silent about it. He'd been through way too much crap for something like that to freak him out. It was that Cas wasn't just a man. He was more than that. And that was why he kept silent about it.

He could only see it end two ways. Either they all died or somehow they'd avert the apocalypse and then Cas would head back up to heaven.

It was a depressing thought, really and Dean did not like to dwell on it.

Dean scrubbed a hand across his face and leaned back in the chair with a sigh. He was thinking too much again but there was just nothing much else he could do. He knew he wouldn't be sleeping until Cas woke up.
