I write this from a weird narration. It's from Dean's perspective... but like... I'm narrating it, just to give it a hint of humor.

Also, sorry if it gets emotional. I wrote it nearly immediately following 8-07 and I'm pretty fucked up. I'm literally dead. It was just too much.

Jealous

It was happening.

There was no way Dean could have foreseen it... or his reaction to it. He'd never really expected it, what with all the crap they'd endured in the past.

It was confusing to think of Castiel as a hunter. Even more confusing to think of him as a friend to Sam.

Castiel was always just... his. Not in that way, he thought unconvincingly. No, just as friends. They were always so much closer. I mean, did you see those looks they gave each other? When was Castiel ever looking at Sam like that? Hmm?

Yeah, that's what I thought.

Anyway, Cas started joining Sam on the food-runs. Suddenly, Dean was alone while the pair of new friends were laughing at some grocery store 2 miles down the road. Dean couldn't help but feel... hurt? Lonely? He couldn't quite place the emotion, but it didn't seem appropriate, so like all other awkward emotions, Dean pushed it away.

They would come back with matching smiles, and Dean tried to bury the pit in his stomach that pulled and tugged at his heart like a child without enough attention. And really, he should have given that feeling more attention. Maybe then it wouldn't have built up into an anger that was overwhelming him.

Maybe then he wouldn't turn his head everytime Cas sent that secret smile -Dean's smile- Sam's way. Maybe then he wouldn't clench his fists until scars developed where he'd dug his nails into the skin. Maybe then he wouldn't have begun pushing Cas away. Maybe then Cas wouldn't have projected his own hurt onto his friendship with Sam.

It was a vicious circle.

If only Dean could've seen that all along.

Sam noticed. Sam always noticed. He was smart like that. He knew Dean better than the idiot knew himself. He tried to show his brother what was becoming of them, but Dean was too busy being fed up with him. Dean was too busy ignoring him for that smile. Dean was too busy remembering the way Sam had laughed and Castiel had started smiling and-

His fists were always clenched it seemed.

Castiel pushed him to respond. Castiel pushed him to do anything but push back. He needed Dean more than the oblivious man knew.

Finally, Dean snapped.

They all knew it was coming.

He was avoiding the pair of blooming friends as much as possible, and he was sleeping in the backseat. He was letting Sam drive.

Dean didn't know why the anger was so deep and so black and so all-consuming. He didn't know when Castiel became his his HIS. It had just happened and all of a sudden he couldn't take it anymore.

"What the hell, Cas!" He was shouting. Sam had loudly declared that Cas couldn't attend this food-run. He was, in his own subtle way, pushing the two to talk it over. He just hoped it didn't end too badly. He hoped even more that it didn't end too well; he didn't need those kinds of images engrained into his memories.

Castiel sat there, hands fidgeting in his lap. He always sat so perfectly. Like a fucking angel.

Dean ignored the irony. He ignored everything but the look of pure confusion when Cas looked up into his eyes. He hadn't realize how long it had been since he'd looked into those two blue windows into Castiel's heart.

"Dean, what are you so angry about?" Cas was asking, but all Dean saw was those two blue eyes and his heart was bubbling up in his chest and was the room getting smaller and why weren't his lungs working and-

"Dean?"

"You're just... Sam! I'm.." Dean couldn't string a coherent thought together with those two blue eyes still following his own green pair.

"Dean? Is this what humans call... jealousy?" Castiel asked as he rose up off the bed, tilting his head in that way that just.. Dean's heart wasn't beating normally, there was a stumble as he forgot to breath, and then his heart was off and running, flying faster than he remembered possible.

He blinked, stepping back and shaking his head fervently, "no! What?! No! Cas, I'm-"

"Don't lie to me, Dean."

And there it was. Dean was frozen, he couldn't lie. Not to Cas, not with those two blue eyes and that crooked head tilt and his lips- oh, his lips. Were they always that shade of pink? Were they soft, he wondered. And then he was shaking, and "no, Cas. I'm.."

"Dean."

And then their lips were molding together and the anger was melting and was this what it felt like?

Castiel released a sigh as he pulled back, eyes still searching for the answer he never quite got. And Dean was nodding, "um."

"I got pie!" Sam sang as he grinned, scanning the room for signs of violence.

Castiel smiled, grabbing the pie, "thank you, Sam."

Dean fell back on the bed, not following the past five minutes entirely, but knowing that this problem wasn't quite resolved. If anything... it had just gotten worse.
