So when Cas tries to render a small smile, because it felt like the silence needed to be reacted to - needed one of them to pull off, there’s no way for him to know that it’ll push them over the edge. Dean wrenches away from him, and Cas sees the strings holding him stoic, snap.

“Sonuvabitch, Cas -”

Dean storms up to him, glaring. He’s angry, it almost radiates off of him - just not, per se, at Cas. 

“- we’ve all come such a fucking long way!” He growls, and Cas meets his stare uncertainly, thrown off. This is unpredictable, to say the least. Dean’s positively glowering at him - except it’s through him, like he’s been hollowed out. “We saved the goddamn world, man. Died a combined total of a hell of a lot! Sam’s gone from being an angry teenager to a kickass, new-age Bobby Singer. Dammit Cas, we lost your wings and got them back.”

We lost your wings.

Cas nods, faintly. He still isn’t sure where Dean’s going with this. 

“Back then? You would’ve put two angelic fingers on my forehead, and zapped me the fuck to India, or something.” Dean grits out, edging towards his worst temper. Cas can hear him trying to restrain himself. “But now, you won’t - now, you listen, and you try - because you’ve grown, Cas. You’ve become family, and I -”

Cas doesn’t think about the fact that if Dean isn’t angry at him, there’s no reason to be yelling. Instead, he thinks about the rare haziness in intense, green eyes, and the pain in his crushed voice.

“And I haven’t fucking changed.” Dean ends abruptly, inflicting a scornful glare at the floor, and -

Oh. 

“Dean,” is all Cas says, because he isn't sure Dean’s done yet. They’ve always jumped to conclusions, and realized they were wrong later, but Cas really doesn’t want to interrupt right now. 

“Ten years, we’ve known each other.” Dean looks up again. There’s too much in his eyes. “Forty years, I’ve been hunting. And I’m still the goddamn same, Cas. Angry, pissed-off, worthless. The hits just keep on coming, and all I do is bury myself in the losses, and then Sam or you screws my head on straight and we pull a miracle out of our asses, but end of the day, I’m this fucked-up, hurting piece of shit, and -”

Emotions shine at the corner of Dean’s eyes; years of keeping it all down, finally overcome. With the surfacing ruinness, Dean lets out a strained sound, and lets his head fall. Chin buried in his chest, at last, he forces out. 

“- and I’m still too afraid of flying.”

“Dean.” Cas loses what remained of his reticence, and if Dean has more to say, he can say it with Cas close, hovering near with his hands featherlight along Dean’s arms, wanting to comfort, but not knowing how. Cas wants to be there - but he’s never gotten a chance before. He has no idea how. “Dean, look at me. Please. It’s not like that, Dean, you’re not those things - Dean, you’re one of the best men I know, just, please -”

Cas knows he isn’t doing the most articulate, or efficient job of reassuring the volatile, shaking hunter - almost - in his arms. None of it seems to seep through, however hard he tries. It’s years of repression. Like the other shoe dropping, the facade of being okay just crumbled - and it’d been the most convincing one yet, one Dean’s been hiding under since God was sent away. 

Instead of listening to Cas, Dean’s lost in his head. He scrubs his face with his hands, and then fists them in his hair, screwing his eyes shut. It hurts Cas to be so helpless right now - because no words seem to make a difference.

“I’m scared of it, Cas.” Dean repeats, voice breaking mid-sentence, and the heels of his palms pressed to his eyes.

Cas looks at him, terrified. He wishes he could hug Dean - wrap himself around him in a tight embrace, and not let go until Dean stops shaking, because right now, he’s trembling, but Cas has no idea if he’s allowed to do that. Dean is - well, from what Cas interprets of the situation, he’s having a panic attack, and Cas doesn’t want to cross boundaries. 

Cas just wants to brush off Dean’s tears, which have never been there before, and run his hands through his hair, and caress his temple, and he wants to soothe Dean’s knuckles with his thumbs, and he wants to tell Dean how wonderful he is, again and again until he believes Cas, and then calmly, he wants to take Dean’s hands, and -

That’s probably exactly what Castiel needs to do. 

Dean’s too out of it to register Cas gently plucking Dean’s hands from his face, freeing his hair of their assault - or maybe, he just can’t comprehend Cas holding his hand so tenderly, like it’s some kind of a precious thing, and Cas’s hands curl around his fingers, pushing Dean’s palm against his. 

Dean’s hands are colder than his, so Cas squeezes till Dean’s feel warm, and he looks at Dean as he does it, and Dean’s noticed now, and he’s staring at their hands, held between their chests, and he’s looking such awe - this delicate, beautiful wonder which makes Cas demand from himself why he hasn’t done this before. 

Somehow, as the seconds pass, Dean quietens. 

And as Cas holds on - simply holds on, running the pads of his thumbs on Dean’s skin, Dean’s chest stops heaving. He still looks dazed, and is breathing heavy, when Cas moves insufficiently closer, swaying into Dean’s space. 

“Will you let me try again?” Cas asks, in the same voice he’d have asked, do you trust me, and Dean understands it. 

He keeps looking at their hands. 

“Will you let me take you flying?” Cas says. “And we can hold hands, or if you’ll let me, I can hold you, and I promise it’ll be alright.”

There’s nothing, for a while. 

And then, Dean’s right thumb twitches, tracing the second knuckles of Cas’s fingers, and Cas feels a shadow of solace go through him, nervousness mingling with grace in his veins. 

“I’d let you take me anywhere, Cas.”

Cas feels his heart swell. Dean looks up slowly, seeking out Cas’s eyes, and Cas holds his gaze, and just like that, they’re back to saying things without any words. 

You fell from Heaven. Pulled me out of hell. We’ve been to purgatory together, so believe me, I’ll go to the corners of the world with you. 

“Maine?” Cas ventures, with growing confidence, for a smile - history assures him that Dean’ll join in, and he almost does. Only a wisp, but it’s there. 

“Yeah, but fucking hold me, okay?” Dean huffs, and it’s such a relieving sound of mild exasperation, more than a reach for normalcy, and Cas adores it. He knows Dean isn’t alright - not yet, and he doesn’t know how long it’ll take in the long run, but he knows he’ll be there for Dean. Through all of it, and on the other end. 

This is the farthest they’ve gotten, too. Dean’s hinted at these issues before, but he’s never had a breakdown in front of Cas - or anyone, and he’s never not backed off into a shell, after. This Dean is trying, and it’s wonderful. And it’d be growth, if Cas had ever looked at Dean Winchester, through the lens of an all-knowing immortal, like he’s not the most incredible being in the world, but a specimen, an experience - a phenomena to be analysed. 

Cas looks on, trying to dissect the way Dean’s eyes stay glued to his, unconsciously, and trying to read Dean through them. He can sense faith, and hope, and his resolve is renewed. 

“Well, we’d have to let go, first.” Cas points out, slow, and Dean tentatively does it first, ending up with his arms on his side again. Circling back to awkward, and adorable in his nervousness. But Cas doesn’t let him fold in, and retreat into himself, because now that he’s got Dean saying yes, and Dean asking him to, of course he’s putting his arms around him. 

Of course, he’s putting a hand on Dean’s hip - and drinking in the subtle responses of his body to Cas guiding him closer, and his other hand goes to rest on it’s eternally demarcated place on Dean’s left arm, as he looks up at Dean with all of the admiration and reverence he feels inside, trying to coax it into his eyes, and it’s not even a fraction of a millionth which makes it there, but Dean still blushes, so maybe for now, it’s enough. And then Dean’s hand grazes against Cas’s elbow carefully - because Cas hasn’t asked Dean to touch him yet, (so he doesn’t), but oh, how he wishes he would.

“How are you, Dean?” 

“I’m going to close my eyes.”

“How would you know you’re not scared if you closed your eyes?”

“How do you know I’m not going to be scared?” Dean throws back, still vulnerable, but a lot more himself. It’s a challenge, a flame disguised as a rhetoric, but Cas treats it like a question. And answers, as plainly as he can.

“Because now, you believe in me.”

It’s not a lot of words, and not the most eloquent Cas has ever been, but it conveys so much that it almost stuns Dean again. He nods, jerkily.

I’ve always believed in you.

Dean waits.

Trust is not the same as belief.

Cas decides it’s not worth this moment wasted, to stop for supplies or guns. They can circle back for them. This is it. Dean’s ready right now, and Cas wants to show him how beautiful it can be - and how with Cas, Dean never needs to fear flying.

Castiel would, and has given up his life for Dean Winchester. He’s charred, ruined, and lost his wings. Yet now, the angel shall show him how to live, on those very wings. Life is a string of poetic ironies, threaded together by choices. Love is the first pearl, and courage is the last.

“Cas.” Dean breathes out, as Cas starts to dissociate, focusing himself deep within. Dean stares openly, for Cas’s eyes are closed now, as he reaches through the realms to gather himself. “Of course, I believe in you.” Falls from his lips in an awed whisper, and the sound of his voice is still too much for the frailty of the moment.

That’s when it happens.

“I love you.” Cas lets out, because it seems far too important that Dean knows, and there’s limits to implications which can’t hold him back anymore. They’re going to fly together. 

Dean’s eyes widening is the last thing he sees, before he needs to concentrate his grace again. It feels like giving in to an old habit you’ve had to live without, more than a lover you’ve moved on from - and Dean’s hands grabbing onto him don't even register as they take off. His grand, celestial wings flap, and time hurls them out of their reality. 

Everything fades, and with the sounds, borders, and colors, so does Castiel - once again, heavenly. Everything goes away, stripping their hearts bare and momentum flickers on their skins, as ethereal, sky-like wings render the only one who remains, speechless.

Beholding the magnificence of his angel, love resonating through his ribs, Dean keeps his eyes open. 

*

It never takes too long.

Dean holds on to Cas, with arms clinging around his neck, until the end. It feels like he’s gliding - but somehow also like he’s driving hands-free in the clouds, though he’s surrounded by too much of everything for it to be the sky. He’s not terrified, but he’s overwhelmed, and he’s goddamn living- hell, he’s never lived this much in a breath, because the second he’s trying to replace the oxygen in his lungs, he finds the chasm of warped space start to dissipate. 

The ground under his boots returns, just like that.

He breathes in air - cold, real air, in the middle of a field which is certainly not Kansas, with a full-blown smile on his face which he’s not even thinking about. It still feels like he’s floating, to some imaginative part of his consciousness. It makes his heart slower, and shoulders lift, and he’s unjustifiably happy, and peaceful, and to hell with being afraid, he feels content.

Dean Winchester feels brave again. 

Maybe it’s because of Cas’s words. Maybe it’s because his arms are still fastened around him. Or maybe it’s because, Cas. He’s everything. Dean's been an idiot to have been trying to ignore the things he feels, because if he’d gotten here sooner, he could’ve had more of Cas looking at him like that, and Cas’s hands planted warmly on his sides, and Cas just smiling at him from this close. 

Now, he’s determined to make the most of the time he’s got. 

When Castiel slowly opens his eyes, looking composed again - and a little proud, definitely pleased, almost too lovely, Dean doesn’t hesitate. Doesn’t wait for the voice in his head to catch up, and start second-guessing what he’s wanted to do forever. Dean just lurches forward, grabbing the trenchcoat lapels to reduce the gap, and kisses him. 

Cas responds almost right away, pushing back into the kiss, and Dean, with all of himself, and letting both arms circle Dean’s waist and shoulders, ending up impossibly close. Dean cups Cas’s face, tilting it towards himself, as he kisses him with everything he’s ever felt. There’s gratitude, and apologies, and need, and want, and then there’s the love, and that’s where he stops thinking. 

“Cas, I -” Dean pants, running out of breath. They’ve stopped kissing, and are simply paused in the moment with their foreheads leaned into a reassuring touch. Dean’s waiting to hear himself say it, and he hopes Cas is, too. “I - god, Cas - I love you too.” He takes a full breath. “I love you so much.”

And then Cas breaks into a smile, chest heaving as well, with the corners of his eyes wrinkling, and lips pulling up, and Dean gets to lean in and kiss him again, and he gets to tell Cas he loves him, and tell Cas he loves him every morning, and every time he feels like it’ll burst out of his chest if he doesn’t, and he gets to want Cas to hold him, as they fly, and -

Goddammit, he gets Cas.
