Disclaimer: If I owned Supernatural, there would be no doubt in anyone's mind whether Destiel was canon.
Unbeta'd.
Cas enters the room scared, not scared of Dean, but for Dean. The way Sam had spoken of his brother, he hated knowing that Dean hurt. He appeared with his usual sound of ruffling feathers. Cas looked for Dean, finally finding him curled in on himself, knees to his chest, arms around his legs, slowly rocking himself in time with his sobs. Cas' grace resumed its tearing with more fervor than ever before. He was the reason Dean was like this. The angel managed to choke out "Dea-" before Dean stopped him, shaking his head furiously and muttering, "You're not here. You're not him. He's gone and he's never coming back and my stupid fucking brain hates me and is just trying harder to hurt me. Good job, brain, way to go. Let me reward you with a bullet. At least I'm not alone in Heaven." Castiel puts his hand on Dean's shoulder, Dean tries to shrug it off but Cas won't let him. He fills the man with his grace and Dean finally looks up. He knows that soft, warm, loving feeling. He recognizes the way his soul always tries to tug him closer it Cas. Dean has never felt so relieved in his life. His sobs soften but he's still crying, just silently now. He looks at Cas, his face streaked by quickly falling tears as he accuses "You left. You promised me that you would never leave." Cas sits in front of Dean and sighs softly, sadly "I thought you wanted me to leave." Dean scoffs and shakes his head in disbelief, "Why the fuck would I want that?" Cas' voice gets softer "You told me that I was the reason that you were upset. I didn't want you to be upset." "Cas, you are the reason I'm upset," Dean quickly grabs Cas so he can't leave again. "But it's not you being around that upsets me, I mean, it doesn't mean you being around makes it better, if anything, it makes it worse but I feel better when you're around." Cas tells Dean, quietly but firm, "I don't understand what you mean Dean. Please explain." Dean's tears have stopped by now but his angel's request has him hanging his head again. "I can't really explain, Cas. I couldn't even if I wanted to. I've never been good at talking about this stuff. You wanna talk cars and classic rock, you come to me. This stuff is Sammy's specialty." Cas nods his head slowly, finally gaining a tiny bit more understanding from Dean's words. "You're talking about feelings; emotions." Dean stays silent but nods slowly. Cas continues, even more slowly "You feel emotions, towards me." Dean stays still this time. "You love Sam as your brother and you care about me as your friend." Dean nods. "Dean, I already know these things, why are they suddenly upsetting you?" Dean manages to get out the word "More." Cas stares at him for a moment. "More what Dean?" "I feel more than what you said." Cas let's out a tiny huff of irritation before he remembers the situation he's in. "I know you feel more than that. I've also seen you express anger, hatred, pain, joy, comf-" Dean shakes his head and cuts Cas off. "You. I feel more about you." Cas looks more confused than ever. "What do you feel for me, Dean?" Dean shakes his head and tears fall, only this time they're joined with a gently mocking laughter. "Cas you're such an idiot sometimes." Cas tenses when Dean moves toward him but relaxes the moment their lips touch. It's not passionate or hot but not chaste or sweet either, it's just a way for both of them to tell the other "I love you, I always will and I'll never leave."
It's possible this is the end of the story. I had a smutty chapter but my Dad screwed up and I lost it. Hopefully I'll get it back.
