Sam is used to all the weird and annoying things his brother does. He's used to finding socks in the sink and really old food in the fridge. He's used to hearing Dean mumble in his sleep. Dean has been doing all these things for as long as Sam can remember.

So when he hears Dean basically groan in his sleep, he just rolls over and covers his head with the blanket. He's so used to it that he barely notices it. It takes him about half a minute to realise he's never heard Dean groan like this before. Worried that he might have somehow manages to hurt himself while sleeping (it wouldn't be the first time), Sam supposed he should probably check. He rolls over again so that he's facing Dean's bed and opens his eyes. But Dean's not in his bed. Looking around the room Sam notices what appears to be two people standing near the couch. He lets out a sigh as he realises one of them is Dean. He wonders how Dean manages to get random girls to come over at 3am and sighs again because he knows Dean will never tell him how.

As he goes lay back down Dean stops making out with the girl... a complete feeling of bewilderment comes over Sam as he thinks he can see Castiel standing right where he thought the girl would be. Confused he looks at Dean, who has the look of a little kid caught with his hand in the cookie jar. He can also see when Castiel appears to grin, and then do a horrible job of hiding it. Castiel... with emotions.... and standing where Dean's girl was. Early morning really doesn't agree with Sam.

"What the hell?!?" The thought dawns on him slowly, his brain all mushy from sleep. There was no girl. There was just Dean. And Castiel. Dean with Castiel. Sam definitely wasn't used to this.

"Uhhh.... hey Sammy" Dean tries to sound nonchalant. And fails, miserably.

"Dean, what the fuck is going on? I could've sworn I just saw you make out with..." Unable to say it Sam motions towards Castiel, who looks as calm as ever.

"Well, uhh... yeah.... you know..." Sam doesn't think he's ever heard his brother stutter as much as this.

"That night you went out with Ruby, Dean asked me to be company for him" Castiel glances at Dean, as if he's not sure if he should go on.

"That night with Ruby?"

"In Iowa" Dean managed to make a sentence, even if it was short.

"Oh right." Sam still feeling confused as to what this has to do with what just happened. Not entirely sure this isn't a dream.

Dean looks at Castiel and nods.

"Right, I was pretty pissed at you, so I invited him over... We pretty much just sat and watched some TV for a while. You were there for most of it. After you went to bed a movie came on, a rom-com. Before I knew it he was on top of me, apparently trying to re-enact the movie" Dean grimaces as he mentions romantic comedies, still unable to stand them.

Sam looks at Castiel, who isn't denying anything Dean said. He even looks straight back at Sam.

"My brother... made out... with... an angel..." Dean was always one-upping Sam. Sam gets a bullseye, Dean gets two. Sam buys himself motorbike, Dean gets a car from their dad. Sam starts dating a demon, Dean makes out with an angel.

"Anyways... Cas was showing up randomly for a few weeks, and then he stopped"

"That's why Dean appeared so angry and unhappy" Castiel's input earned him a pretty fierce glance from Dean, but he just grinned in response. It was going to take a while to get used to seeing his with emotions... and with Dean.

When Sam didn't say anything Dean decided it was time to continue. "And this is the first time I've seen him since that thing with Alastair. There, story done."

"But, he's a man" Which Sam would have thought was obvious by the way they used 'he' in reference to him.

Dean rolled his eyes when he heard this and looked pointedly at Castiel, who actually let out a laugh. A laugh!

"Sam, how stupid do you think I am? I know he's a man."

Huh. Whatever this thing between the two of them was, Sam was glad to see Dean was back to making jokes. It would actually explain a lot, especially because Dean hasn't brought a girl home in months. But Dean with a man? Dean... gay? Sam definitely never saw this coming.

----------------------------------------

The next morning he opens his eyes to late morning sun peeking under the curtains and the smell of coffee. Mmmmmmm.... Coffee seems like a good enough reason to get out of bed. Sam is surprised that Dean let him sleep in. He pushes the blanket off and looks around with bleary eyes. He can see Dean sitting with someone on the couch. He rubs his eyes and that someone becomes clear, it's Castiel. The memories of the night coming rushing back to Sam. Everything about his brother and Castiel, it all comes back.

They both look at him as he gets up and pours the coffee. Unsure of what to do Sam stands by the bench. What if it was just a really weird dream? Dean wouldn't be too happy to hear about it. But what if it wasn't? How would he feel about his brother being with man? He honestly had no idea. It's not something he's thought about before. It would be weird to wake up to Castiel being here every morning though.

"Morning Sammy"

"Hello Sam"

They speak at exactly the same time. That was going to take some getting used to.

"Hey guys"

"I must go, someone is trying to open another seal" Castiel looks apologisingly at Dean.

"I will" Castiel says, as if he's answering a question, even though none was asked. Without another word the angel leans over to give Dean a quick peck on the lips and then he's gone. The kissing was definitely going to take some getting used to.

Dean looks hesitantly at Sam. "What do you think?"

"It's definitely weird. And it's going to take some getting used to. Maybe even more so then you leaving your socks in the sink"

"When have I ever done that?" Dean smiles. Sam thinks of the past few weeks and how bad Dean's mood was, happy that those days seem to be over.

"Come on, seriously? All the time!"

----------------------------

Castiel reappears a few hours later. Actually knocking on the door for what Sam supposes is the first time ever. Dean answers the door and grins.

"Since when do you knock?" Dean mocks.

"There's a first time for everything" Castiel replies, giving Dean a look that Sam could probably never understand.

(I wasn't all that happy with this chapter, but I figured Sam's POV would be needed for it. I find Sam harder to write for then Dean, I'm not sure why. There will probably be one more Dean chapter after this and then I'll run out of ideas, and it will become long and boring, which is never good, so I'll probably just end it.
When I signed up to this I actually wasn't expecting anyone to read what I wrote, so thanks ^_^)
