Post your creations to #SPNsummer starting July 15th! 2026
Oooh, something fun to do when I need a break from banging my head on the table over my big bang writing challenges. Fun prompty palate cleansers, if you will. I don’t know that I’ll do all of these, but I will try to do a few drabbles here and there. I MISS the days of doing drabbles.
You can subscribe to MY AO3 to get updates when I post something, and/or check out the SPN Summer AO3 Collection later on when folks begin posting.
Idk why but sometimes people really struggle to truly understand Dean's atheism and it's depth and motivations uk? It's not something that's caused by his issues or smth. It's a core character trait. Sam's faith vs. Dean's lack of it is literally essential parts of their characters. Their lives as hunters and children of John as well as chosen sacrificial lambs for the apocalypse all lead to that attitude.
And I think this extends to destiel too. Cas is the man with faith. Who then proceeded to spend several seasons having that faith torn apart. Dean, on the other hand, had his wistful faith torn down in like one season at most. Like a normal human person (who has to deal with cosmic issues no less), he has an evolving relationship with faith of any kind. But he's really clear. At the end of the day, he doesn't believe in anyone or anything all-powerful and uncaring. He believes in his loved ones. In his family. In Earth and Humanity. In his own choice of putting the well-being of the most vulnerable (humanity in a cosmic sense) people. In caring so much about all of it even when it breaks you apart.
This is where his faith in Cas comes in. I think it's an important part of the narrative that Dean's faith in Cas isn't godly. It's not religious. It's devotion in a painfully human way. He believes in Cas because he loves him so much as a person. Not as an angel. Not as a weapon. Not as the new replacement for God. His love for Cas begets blind faith in the man because he loves him like he would love a human partner. He includes Cas in his daily domestic life. He enlists Cas's help in all their affairs. He wants to take care of Cas when he's weak or sick. He relies on him like a partner would. Like a spouse would. He puts him in a cowboy hat and takes a lil photo. He prays to him because he wants to connect with him. To him, it's like a text that Cas can't miss. It's a plea to be heard and responded to. He makes him pb and j sandwiches. He takes him to a brothel. He wants him to learn how to flirt even when it drives him insane. He called him by his nickname within minutes of meeting him. He dropped the godly suffix instantly. He wanted to tell Cas he's so much more than just a weapon. He thinks Cas is a dork. He thinks Cas is just a lil guy. He wants him so close at all times. It isn't religious. It's really important to me because Cas is a character who has spent all of time in a faith-based genocidal military cult. He doesn't need to be seen as a God. (Famously didn't work out so hot for him). He needs someone who will tell him he's a person and hold him close in all his intensity. He needs someone to tell him he's Good enough as a person, not a shield. And THAT'S insane to Cas. That's not a thing he ever imagined he could have. And that's why it matters so much that he gets to have it.
the best fanfiction you've ever read was written by a woman in her 40s before she made dinner for her kids. it was written by a teenager after school when they should've been studying for a history test. and a barista came up with the idea while they cleaned the espresso machine and busser fact-checked it on their break and the post-doc edited between writing grant proposals and the nurse apologized for typos in the notes after a long shift and behind every drabble and one-shot and multi-chapter fic there is a person with a wonderful and interesting and chaotic life and it is such a privilege that we get to be a part of it because they decided to do this thing we all share, for fun.
Yep. I’m the mom in her 40s that writes through the night with little bodies pressed in close, when the rest of the house is fast asleep. I brainstorm and/or write at the playground while the kids run and play, while waiting in the car in pick up line, at the library during storytime, in the shower, while making dinner, on walks, at the grocery store… it never stops.
I think it’s funny and sad when a younger person learns about how many older folks are in the same fandom spaces as them. Funny because they’re so innocently taken aback by it, and sad because they thought that there was some magical age where they’d have to ‘grow up’ and couldn’t participate anymore.
You don’t have to give it up.
You can still love your shows, your ships, and the stories. You don’t have to give any of it up unless you want to let it go.

Summary: Dean is a medic with a heart of gold, always ready to lend a helping hand, but when a stranger crash lands in his life and insists that he’s an angel from an alternate universe, Dean learns to take a leap of faith.
Castiel is an angel who struggles with self-doubt while torn between two worlds and two men.
Dean has one goal and one goal only when Castiel goes missing: find his angel and bring him home.
‘you’ve just met yourself. i’ve known you for years’ is still the most romantic thing i’ve ever heard and they let my favorite little cornfed closetcase say it on live television to another man. incredible.

Summary: Cas is firmly placed into the ‘friend zone’ by Dean after his possession. With no home in heaven, nor a consistently reliable one on earth, the rejection is one more torment to bear. To ease the ache of unrequited love, he decides to take a page out of the ‘Dean Winchester Playbook’. There must be something to these ‘one night stands’ that he’s only ever read about. After taking painstaking measures to find a willing partner, Cas doesn’t expect Dean to be the one to sit beside him at the bar, and he most certainly doesn’t expect a proposition…but why not him for once?
Dean got scared, okay? He couldn’t tell Cas how he really felt. But Cas going AWOL yet again, especially after a harrowing half-year of trying to save him from Lucifer, sends Dean over the edge. He goes out for a drink (or two, or ten) and meets a young woman who seems vaguely familiar. They talk, they commiserate, and even though his heart isn’t really in it, he offers to sleep with her. What’s the harm? It’s only one night and he doesn’t expect to see her ever again. So why has she just walked into the bunker two weeks after they did ‘the do’?
I started this story in 2018. When I brushed it off for this bang, I only had about 10k words in a jumbled mess. It kinda blew up into a big thing at almost 100k words and I’m sad that it’s over. I honestly don’t know what to do with myself after pouring so much into it these last few months, losing sleep, becoming a hermit, lol.
A lot of my heart is in this story. There are so many pieces from my life experience woven throughout.
I do want to write a time stamp/epilogue so be sure to subscribe on AO3 if you enjoy the story.
It was a pleasure and honor to team up with @colorlessjay. I am blown away with the artwork. It is beyond what I expected, truly.
My beta, Rachel, was with me for weeks helping to proofread and cheer me on. I don’t think I would’ve had the confidence to post without her suggestions and encouragement. Phew, girl, we made it!
2025 hot destiel take: I've always believed that Castiel saying "the one thing I want, it's something I know I can't have" isn't some bleak "because Dean doesn't wanna dick Cas down" admission, it's "because, by confessing, the empty will take Cas, there's literally nothing for him to 'have' afterwards." His punishment isn't unrequited love, it's unfinished love. This is why happiness isn't in the having, it's in just saying it. Because it's all he gets. Cas doesn't get sucked into the empty thinking Dean could never love him back, he goes peacefully knowing that he does - that it doesn't matter that they don't get to experience the other side of the confession because confessing was fulfilling enough :')

An Alternate S12 Story (without Mary and BMOL).
Excerpt: “Dean, there’s more,” Cas says, interrupting his wretched thoughts. More? Dean doesn’t think he can handle more. It's bad enough they slept together.
“I think you should go, Cas,” he says, hating that his voice breaks. “Put your regular meat-suit back on ’cause we got real work to do, so let’s just pretend this never happened.” He swallows. “‘This kind of distraction, it’s–” He huffs humorlessly. Simply put, this is something that can’t happen again.
“I can’t do that,” Cas’ soft but stern tone cuts Dean off.
“You can’t what? Put on your meat-suit, or pretend it didn’t happen?”
“Both.”
“Are you telling me you’re stuck in that?” Dean’s heart can’t take much more of this. This isn’t Cas.
“It would appear I’m stuck, yes. Temporarily.” Cas gently clears his throat and bows his head slightly, loose hair falling over slender shoulders, eyes glancing away to focus on some dust bunny across the floor. “For about nine months. Well, to be more accurate, less than that at this point.”
“Why? You waiting on a power-up to make the change?” Dean asks suspiciously and despite everything, with a degree of concern. He is so blindingly angry that he didn’t even think that something could be wrong. “You cursed or under some spell?”
“Dean,” Cas says forcefully, looking up at him, unfamiliar hazel eyes boring insistently into his own green ones like it'll make Dean understand the meaning behind the words better. “Nine. Months.”
“Is that supposed to mean something to me?” Dean wracks his brain trying to figure out what kind of curse has a time restriction on it like that.
Cas takes a deep breath, closes his eyes, and murmurs, “I’m pregnant.”
The room falls silent. Everything goes still. All Dean can hear is his own shuddery breathing, and then the floor shifts beneath his feet and his vision goes fuzzy around the edges. Before he can fall, small hands cup his elbows to help keep him upright. The unexpected touch shocks him back to the present.
It figures that just when his life was on a trajectory toward something a bit more normal, where there were no more eldritch monstrosities and apocalypses to thwart, when he might've been able to finally admit out loud how he truly feels about one very misguided, but beautifully faithful fallen angel… it all falls apart with two words.
“Well, mazel tov,” he says, yanking his arms away and taking a step back. Bitterness, jealousy, anger, and all of these other ugly feelings begin a riot in his gut. “You even know whose it is, huh? I mean, it’s been a couple months.” He doesn’t think he can stand on his own two feet anymore so he sits down heavily on the edge of his bed, sinking into the memory foam a little. “How many guys..? Forget it. I don't think I wanna know.”
Cas moves closer and scoffs indignantly. “I only had the one night, with one person,” he asserts. “You."
Breaking my usual fandom content. I have so much more to say, so many questions, so many ideas. Alas, I am only going to touch on one thought thread.
K-pop Demon Hunters spoilers below.
Where darkness meets the light: Rumi in white/gold and Jinu in black.
So I don’t believe Jinu’s soul is solely confined to Rumi’s sword, which is the general consensus that I’m seeing on various posts.
My thing is that I believe he plays a much larger role than that. I believe he is a part of the new Honmoon itself. Her sword is formed out of the Honmoon, of course, and he was integral in forging the new one that powered her up, helping her to defeat the monster that controlled him for almost his entire existence.
But he isn’t just ‘in a sword’. He is woven into the shield, the Honmoon, an extension of her, of everyone. They’re all interconnected.
I think that him lighting up the Honmoon in ‘Free’ as he got his soul back was the foreshadowing of him becoming a part of it in the end (of movie 1, anyway, because my baby is coming back in a sequel or else we’re going to have some big problems).
This is so important for his redemption arc and character development. Where he failed to protect his family centuries ago, he now protects everyone. 🥲
It's really the unseen that gets you in destiel. First time you see them meet is NOT the first time. Camera panning out to leave them staring at each other in an alley. Prayer every night in purgatory but you don't hear it. Heaven Can't Wait fanfic gap. Everyone knowing so much about Cas but you never see Dean talk about him. Cas' phone screen blown up with calls&texts you can't read. Mentioning the Tombstone watch in the Dean cave that only Cas knows about. Gossiping offscreen about the cardigan. etc
The excruciatingly long stretches of looking at Dean raking leaves, carrying the trenchcoat from car to car. Of waiting for the other to come back from the heavenly war, from captivity. Man, they had so much. So much domesticity, so much yearning, longing to be in contact, to just be with each other, to be safe. To love.
Like, holy hell, I still can’t believe they had THIS scene where they showed that Cas kept a homemade ‘Dean Winchester Mixtape’ in his coat right over his heart. And when he tried to return it because he felt unworthy and a bit of an outlier, he unwittingly broke Dean’s bruised heart a little bit.
But never once were we shown the entire process. Never shown the hours it would’ve taken for Dean to carefully record each song.
Or, how he penned the label with his tongue caught between his lips so he would take his time not to smudge the ink, all neat and tidy.
Or how he might’ve kept it in his pocket for days, waiting for the right time to give it over, and finally, hastily, chucking it over to Cas with sweaty palms and a pretty blush, his sour stomach twisted from nerves…
Or Cas’ bafflement over the unexpected gift because angels don’t just get gifts, at least not impractical, sentimental ones. (I don’t think he’d be surprised that a hardened hunter like Dean made it in the first place because he knows Dean to be the most loving and caring human on earth… he would just be bewildered that Dean chose HIM to receive it.)
And never were we shown WHEN. How long had Cas had it? By the time we were made aware of its existence, Cas had been AWOL for a while because we had been watching Dean pace the hallways and bite his nails, waiting for replies to texts and voicemails that were going unanswered. Somewhere in the quiet past, between hunts and apocalypses and fights and separations, Dean missed Cas so much that he lovingly created for him a token of his affections. And Cas just tucked it into his trench coat and carried it with him, a constant reminder of who he was fighting for, the cogs gently clacking inside the plastic housing loud enough for his ears only each time that he moved.
The writers just—POOF—dropped the echoes of it into the show and let us dream up how it might’ve happened. They didn’t have to, they could’ve omitted the mixtape detail completely without otherwise changing the rest of the scene, but they did do it.
I love the negative spaces and the unsaid on this show so much, especially regarding Destiel. It’s like being an archeologist and uncovering a new artifact, trying to guess what it was used for and by who and how because we don’t have videos or diaries from those eras, only the remains and our best guesses.
There are a lot of Casless episodes where his presence is loudest because Dean’s heart bleeds from where it hangs on his sleeve, invisibly tethered to wherever his angel is, to whatever he’s doing, always worrying and pining.
but why does dean's voice actually get 100 times softer every time he asks about cas or calls him or talks to him?? i thought i was imagining it but now i didn't watch spn for a few days and today i watched some episodes of s11 and cas is back in the bunker because of the spell rowena put on him. and each time dean checks on him or just asks sam how cas is doing his voice goes teddy bear quality
This is very, very true. He uses such a tender tone with Cas much of the time, and it carries throughout their entire history together. Not only that, but the way Dean bodily protects Cas (who doesn’t need protecting), and finds reasons to touch or caress him ... 🥹
We've been burned so many times, hoping for some kind of intimacy between Jensen and Misha's characters (whoever they may be), that I don't want to get my hopes up with The Boys; but honestly, if there ever was a show to finally cross that (stupid) boundary and give the people what they've been begging for for literal decades, it would be The Boys.
I was just telling my husband tonight that I need to bring my expectations way, way, waaaaaaay down because I was conjuring up all sorts of delicious ideas that would be too good to be true. My expectations need to come down to earth and be stuffed sub-level. That way, whatever we get, I’ll likely be okay with it.
