Castiel feels a void somewhere inside of him, now that Dean is gone. He tries to fill it out—he attempts to help Sam with cases, but Sam doesn’t even have to say anything for Cas to know his bumbling is more of a hindrance than a help.
That leaves him with nothing to do but agonize over his failing grace and fruitlessly search for leads on Dean. He sets up camp at a motel somewhere in Ohio and tries his best to remember how Sam had taught him to search for signs of demonic activity. He does this for weeks, until the days passing seem to blur together, until, suddenly, it isn’t so fruitless. He finds Dean.
The worst part is it isn’t even on purpose.
Castiel has had enough of staring at his computer screen, so he leaves the stuffy motel room. He figures his grace was weak enough that he can actually get well and truly drunk, so he goes to a bar, intent on drinking until he can’t feel anything anymore. That plan flies out the window when he sees Dean.
Cas's first thought is he’s hallucinating. His grace is sputtering out, and it’s just showing him what he wants to see most in his final moments. Why would Dean be here, in this dank dive that doesn’t even have peanuts, after Castiel’s spent almost a month looking for him with nothing to show?
Castiel drinks in this picture of Dean—even if it isn’t real, he’ll take what he can get. It’s the thing he’s been yearning for for weeks, after all, but he freezes when he looks a little deeper. There are putrid green swirls floating around Dean’s soul, slowly puffing through the cracks on its blackened surface. The soul that used to be the picture of perfection, that used to be the thing that filled Cas' void. He feels vaguely ill. The closest to this he’s ever seen Dean’s soul is when he pulled him out of Hell, all those years ago.
Dean’s soul had been tattered then, too, but iridescent light still sputtered weakly from within: its feeble attempts at mending itself back together. Castiel remembers the way he had clutched Dean’s soul close, feeling the emanation of its soft energy and reconciling it with his grace before letting it slip back into Dean’s body.
Now, there’s only a dim light struggling to pass the darkened shell, never mind having enough energy for any patch work. He recalls the way Dean’s soul used to reach out to meet his grace, to bridge any distance between them, and he grimaces as he compares it to this new sight, the way it seems to shrink in on itself, trying to get as far away from the holy light as it can.
Cas's eyes drift back to the terrestrial plane, and he’s convinced this vision of Dean isn’t some mercy his grace is giving—it’s cruelty to show him Dean’s soul like this, even if it does mean he gets to see Dean for the first time in what seems like much longer than eternity. It gnaws at him that the brightest thing he’s ever laid eyes on has been corrupted, defiled, and twisted into what sits before him now.
His feet move forward against his will, propelling him towards Dean, who raises a hand to the bartender. By the time Cas drops into the seat next to Dean, there’s a drink waiting for him. He reaches out and downs it.
Dean turns and looks up at Cas through his eyelashes. “Rough day?”
“Rough day,” Castiel echoes tonelessly, “That’s all you have to say?”
“And what exactly do you want me to say, Cas? Long time, no see? You should lose the trench so I can get a better view of your ass?”
Castiel flushes. Now he knows this isn’t his Dean, and it isn’t a Dean his grace cooked up, either. He fiddles with his shot glass and shrugs.
Dean huffs a laugh. “You really tracked me down and didn’t even think of anything to say? Here I was, thinking you were a boy scout.”
“Who says I tracked you down?” Cas counters, even though that’s been his only goal for a while now. He swears he sees a flicker of hurt cross Dean’s face. Not Dean, Cas reminds himself sternly, even though it’s so easy to get caught up in the sight, the scent, and the nearness of this not-Dean.
“So if you’re not here for me, what then?”
In a quiet voice, Cas answers, “I just wanted to forget for a night.”
“Yeah? What do you have that you need to forget? Did Sam start nagging at you to take better care of yourself?”
“I’ve been alive for millennia, Dean. I have plenty to try to forget.” A wry grin tugs at his lips, but Castiel’s not sure if he should give himself the permission to smile.
“In that case, why turn to alcohol? I’m right here, baby,” Dean purrs, so close that Cas can feel the heat radiating off him.
He turns to Dean in surprise, his eyes dropping down to Dean’s lips before he remembers—not Dean. His Dean wouldn’t want this. Dean doesn’t miss the glance, though, and he smirks. “Interested?”
“N-no. It wouldn’t be right,” Cas stutters, and he can’t remember ever feeling so unnerved. Dean’s not supposed to act like this, has never shown this kind of interest in Cas before.
“Yeah? It feels plenty right to me. An angel and a demon walk into a bar… It’s up to you how that story ends.”
Even with Cas's suspicions of Dean being a demon confirmed, he still feels inexplicably drawn to him. Well, maybe inexplicably is a bit of a stretch; Castiel makes it a habit to not lie to himself, and he’s been drawn to Dean from the very start. Despite this, when Dean leans in, Cas puts a hand to Dean’s chest, keeping him at arm’s length. “I shouldn’t.”
“Good thing I’ve got all night to change your mind,” Dean says with a grin that sets Cas on edge. He swallows hard as Dean’s true face flickers into view, strengthening his resolve, but he can’t make himself get up from his seat and deprive himself of this opportunity to just exist in Dean’s orbit again.
