A/N: Bit of fluffy Destiel for you! This takes place in Hunter Heroici (I think?) and it's what I think should have happened instead of Sammy the Moose coming in. This was originally going to be an angry-sex thing, but I've been craving fluff so here it is.
"Cas, talk to me."
Castiel shook his head, looking like a little kid in timeout. "No."
Dean sighed. "Come on, man. What's eating at you? You've looked like someone stole your lollipop. Talk to me."
"I said no, Dean! Please, just...let me be. My burdens are not yours to bear."
"Yeah, well. I've been to Hell and Purgatory too, Cas. I'm pretty sure it can't get any worse." Dean rubbed his eyes wearily, visions of the horrors he witnessed and took part in flashing before them.
Castiel sighed deeply. Dean thought he could see tears shining in the angel's impossibly blue eyes, but tried not to think about it. "After what I did to Heaven, after the chaos that I wreaked...Dean, I'm afraid I might kill myself."
Dean's entire body went numb. A thousand different pictures went racing through his mind-Cas saving him, one of the angel's swords, Cas refusing Dean's offer in Purgatory, the dirty trenchcoat left over from his swim with the Leviathans. But then a new image surfaced-not a memory. Dean had no recollection of such a thing ever happening and he blushed at the sight of it.
He was shaken from his reverie by Cas swallowing hard. The angel was looking in the other direction, but Dean could tell that he was crying.
But angels couldn't cry, could they? Dean had seen tons of angels, but none of them were emotionally unstable enough to cry. They basically portrayed no emotion at all, except for Gabriel and Balthazar's sarcasm and Anna, before she remembered her angel status.
All dead, the lot of them. Except Castiel.
He had shown emotions, had he not? He had rescued Dean from Hell and saved him a thousand times. He had beaten Dean to a bloody pulp when the hunter had shown signs of stopping. He had gone with him to Purgatory and back.
"Look, Cas," Dean said, his voice hoarse. The angel turned to him.
"I know that you regret what you did. But it's not your fault. You weren't yourself. It wasn't you that was in there, Cas. It was the Leviathans the whole time. And guess what? We killed 'em. We ganked all of those sons-of-bitches and they can't get inside you anymore. So stop beating yourself up about it."
Cas smiled. "Thank you, Dean," he whispered. "But I still-"
The hunter stood up and stomped over to Cas, who was babbling about how even though he was not in control, it was still him that had done it and-
The words died in Cas' throat as Dean pulled him up by his trenchcoat and kissed him so hard he thought he would faint.
"Oh," he muttered, blinking rapidly.
Dean smiled and gently placed the angel back on the cheap motel bed. "Yeah."
