WARNINGS: CHARACTER DEATH, AU
"Trust me." Dean had said, a confident smirk on his face. Castiel had trusted him off the bat, because Dean was his best friend-his boyfriend, and that's what best friends did. They weren't actually going to kill somebody, you know? It was just a harmless prank. It was supposed to be a harmless prank.
But something went wrong.
And now Castiel was staring at a barrel of a gun, Dean unconscious beside him.
It was just supposed to be a prank.
"I don't like Sammy's new girlfriend." Dean murmured quietly, moving around a bit so he could untangle himself from his sheets. Instead, it seemed to entangle him even more. His voice was sleepy and his guard low. Castiel shrugged. "I don't like Ruby too." He said honestly, somehow feeling the need to admit that.
Dean smiled at him, his eyes flickering open to meet Castiel's and that warmed Castiel up in a way blankets never could.
"Come back here, Cas." He muttered, lifting his blanket up. Castiel rolled his eyes and slipped in beside Dean's naked body. Dean threw his leg over Castiel's hips and grinded against him a bit. Castiel's breath hitched and he stifled a moan.
"Aw, don't be like that." Dean muttered, finally starting to awaken. He pushed Castiel on to his back and straddled his waist. He leaned towards Castiel's body, pressing their chests together and swiveling his hips into Castiel's before finally kissing him.
Their tongues entangled with each other, and Castiel thought that was the end of the issue about Sam Winchester's girlfriend.
It wasn't.
A week after that, Dean was floating in the pool, a little grin on his lips as he suggested to Castiel that they prank Ruby. Just a simple prank—like the ones he always did to his friends.
Castiel shrugged and agreed.
"What happened in that bathroom?" Detective Michael asked him, his eyes narrowed. Castiel swallowed and didn't answer, looking down.
"Castiel. Someone diedhere, and we think you have something to do with this." The other detective, Lucifer, said quietly. Castiel's eyes watered as he clenched his fists.
"It was an accident. Don't arrest Dean, please." He whispered. The detectives glanced at each other, before Michael smiled thinly.
"We're not promising anything, Castiel, but if you tell us what happened, then Dean's punishment… will be less severe."
Castiel bit his lip, looking up at them, hope flashing in his eyes. "We drowned her." He admitted quietly.
"Well." Lucifer drawled. "That explains Dean's handprints on her neck. But why?"
Castiel shifted in his seat. "Dean didn't like her. She was a bitch."
"Why did you go along with him? You seem like a very good teen. Straight As, loving parents. Everything.Why, Castiel?" Michael asked, leaning towards Castiel a bit. Castiel shifted away and clenched his fists on his table.
"He's my boyfriend." Castiel replied, staring at his hands. "I love him, okay?"
Silence. Michael swallowed and then nodded. "You're free to go." He said quietly and stepped away. Castiel nodded and stood up, rushing towards the door. He opened it and there, outside, was Dean. Castiel's eyes widened and he tackled Dean, kissing him furiously.
"I am so sorry." Castiel whispered. Dean shook his head before pressing his lips against Castiel's neck. Not a kiss, just a reassurance.
"It's okay. I'm… I'm sorry, Cas. You gotta forgive me, okay?" Dean murmured against Castiel's skin. Castiel nodded, and then Dean was taken inside by the officers to be questioned.
The case of Ruby was closed. Dean and Castiel were sentenced to a year in jail, making it out easily.
