Disclaimer: I don't own SPN.

I know that I really should stick another fight in since we haven't had one for months…but honestly? Some days I feel like doing nothing but lying around and I often get down and have mood swings, to the point where my mum thinks I'm depressed. I don't know how true that is (though I did have a bit of a breakdown today) but being able to churn out a fluffy Destiel moment a day really helps, so I'd have to be in a really good mood to be able to write angst. And you guys are just unbelievable – waking up to all of your reviews really puts a smile on my face. So thanks! :D

Thanks to Siriusly loving densi, masterjediratgrl31, CaptianAckles, mollienaturerocks, RangerHorseTug and Avalin Rose Ellyot for your reviews :)

130. Firework

"Are you even gonna tell me where we're going?" Sam complained as he slid into the front seat of the Impala. Castiel got into the back, where he stretched out comfortably; he much preferred riding shotgun with Dean but he did enjoy being able to stretch in the back.

"Nope!" Dean said cheerfully. "Now, c'mon! Charlie and Rosie are already there and they'll kill us if we're late!"

"For what?" Sam complained but Dean just ignored him. They pulled out of the bunker garage and began to cruise down the road, Dean humming an AC/DC song and pointedly ignoring all of Sam's questions.

"If it helps, I don't know anything either," Castiel said. They drove in silence after that, though Sam was shooting Dean dirtier and dirtier looks. Eventually, they pulled up at an empty field, where Castiel could see two figures a short distance away in the dark.

"Finally!" Charlie's voice called as they got out of the car and approached her and the other figure, who Castiel knew to be Rose. "You took your time!"

"Are they ready?" Dean replied. Charlie gave him a thumbs-up in reply.

"Dean, what's going on?" Sam snapped.

"Dean's being a sweet big brother, that's what," Rose said, standing on the tip of her toes to give him a quick kiss. When she broke away, she bent down, picked up a thin tube and placed it in Sam's hand. Sam stared down at it, his face cycling from confused to stunned and then to utterly joyful. He whipped his head around to stare at Dean, a wide smile breaking across his face.

"Totally Charlie and Rosie's fault," Dean grinned, raising his hands. "Charlie re-read that book where we died and went to Heaven and then came back and Rose remembered that fourth of July when we burnt down that field. So I thought that we could do it for New Year's, especially since we didn't do anything last year, and we got together and planned this." He gestured to the big box of fireworks on the ground. "Next year, we'll go and see some real fireworks but for now…"

"I – Dean – wow," was all Sam could say. Dean clapped him on the shoulder and then moved aside so that Sam could pull Rose into a swift, deep kiss.

"Sure, it's not like I helped or anything!" Charlie said loudly, though she was grinning. "And if you're gonna go at it right here like Dean and Cas always do then please tell us so we can move far away. Like, other side of the country far away."

Sam and Rose broke apart after a few moments and Rose kneeled down to get a firework for herself. Charlie, Dean and Castiel snatched up fireworks and then Charlie pulled out her phone, which illuminated her face in a bluish glow.

"One minute!" she announced gleefully. "I'll count us down!"

As Charlie counted down from sixty, Castiel found himself watching Dean. His human's eyes were fixed on Sam, who was holding Rose close to him with one arm, and he had a rare, content smile on his face that Castiel had only seen sparingly. His heart began to fill with emotion and when Charlie counted down the final twenty seconds, Dean took out his lighter and lit everybody's fireworks.

"Here we go!" Charlie trilled. "Ten seconds!"

Castiel kept his eyes on Dean and as Charlie shouted, "HAPPY NEW YEAR!" and the fireworks went spiralling off into the sky and exploded in bursts of colour, he felt his heart swell at the pure joy on Dean's face. He wrapped his arms around Dean and pressed his lips to his human's.

"I love you so much, Dean," he said when they broke apart, enjoying how Dean's face was illuminated by the coloured fireworks that Sam, Rose and Charlie were still setting off. "I don't think I've ever loved anybody this much throughout my millennia of existence. Falling for you was one of the best events of my life."

It was hard to tell in the multi-coloured light but Dean's cheeks seemed to be a little red.

"Stop being adorably honest, Cas," he grumbled. "You know I can't compete with crap like that."

Castiel pressed a kiss to Dean's cheek, enjoying the prickling of stubble under his lips.

"You don't need to," he said firmly. "I am already very much aware of the extent of your feelings for me, Dean."

"You're not," Dean denied. Castiel frowned in confusion. He did know how much Dean loved him! "You really don't know just how – just how much I love you, Cas." He pulled Castiel close to him, trapping him in his arms, and Castiel embraced him back and rested his head on Dean's shoulder, ignoring how his glasses pressed uncomfortably into his face thanks to Dean's head. "I love you so goddamn much and I – I can't lose you, Cas. Ever." He pulled back slightly so that Castiel could see the desperation and fear in his eyes. "Promise me, Cas. Promise me you'll never leave me. 'Cause that'd – that'd just destroy me…"

Castiel recognised just how difficult it must have been for Dean to confess both that he was vulnerable and not the tough man that everybody else saw and that Castiel was a large reason for that vulnerability. Feeling honoured and privileged that he had been given this insight, he smiled and gently kissed his human.

"I will never leave you, Dean," he said firmly. "You know that. And even if I'm forced to leave you, I will always find my way back. Losing you would be just as devastating to me as losing me would be to you. I love you."

Dean's face split into a wide grin and he pushed Castiel's head onto his chest, stroking his hair.

"Love you too, Cas."
