Post #1 remains open for fills.
THIS POST IS NOW CLOSED TO NEW PROMPTS. YOU SHOULD ENTER NEW PROMPTS ON POST #3.
You may continue to fill existing prompts on this post.

Prompts should be one prompt per comment, formatted in this way: fandom, character(s), prompt word/sentence
Prompts may also be open ended, unspecific, or anthropomorphic, such as:
or
Earth geography, sand, I don't like humans very much, either
Prompts for relationships are welcome; a / is used for romantic/sexual relationships and an & for platonic. A prompt that uses both means the relationship can be written as either romantic or platonic, such as:
Prompts may be repeated if they are unfilled; there is no obligation to read through every prompt to make sure yours isn't a repeat. This year's 3SF will stay open for new prompts through Sunday, February 9th.
Respond to your chosen prompt with a short fic of three sentences containing the fandom & characters requested!
Prompts can be filled more than once, as many times as someone has a new idea for them.
No, fills do not need to be exactly three sentences! It's more of a guideline. Please abuse grammar and punctuation as much as desired.
3SF is a Choose Not to Warn space. Spoiler and content warnings are not required, though writers are free to add them if they please. If you see something you don't like, just scroll until you do!
A Dreamwidth account is not needed to participate. Anonymous prompts/fills are welcome, or you can use Open ID. Using an account does make it easier to see people's responses to your fills though!
Cross-posting is encouraged; there is a 3SF Collection on AO3 if you'd like to post fills there as well.
Note that the comm is searchable if you're logged in! Tick the 'include comments' button when searching to easily find prompts for your chosen fandom/characters.
And most importantly, have fun! If you have questions, check the Sticky Info post and if they're not answered there, head to the Contact the Mods post.
Please note we have done a few updates for the rules this year and would appreciate everyone glancing through them!

Date: 2025-01-18 04:57 am (UTC)Angela is honestly surprised by how easy it is to fall into his arms after all this time. She doesn't believe in the whole love languages thing but she could believe that Shawn's is physical contact, because his arms have always been open to her.
"Do your cousins still think I'm Shawn with the Good Hair?" he asks. They're in their hotel room, having left her family reunion. Desiree and Tessa squealed when Angela revealed that this Shawn was the Shawn: the one who found her purse, who wrote her poems, who was ready to cross an ocean to be with her when they were in their twenties. "Shawn with the Good Hair!" Desiree shrieked, and Angela both laughed at the old nickname and cringed, despite Shawn (clearly) being okay with it.
She looks at him, and despite the streaks of gray, the years and his life wearing him down (but not breaking him), she can still see that gleam in his eyes, the spark of adoration that made her knees weak at seventeen, and still makes her heart race now.
She smooths back a stray lock and kisses his cheek. "Of course."

Date: 2025-01-13 03:49 am (UTC)Narnia, Susan
Date: 2025-01-14 12:41 am (UTC)Susan picks up Diana on a whim and the little kitten is making her reconsider that decision by the time she gets her back to her flat that afternoon. The tiny ball of fur is terrified out of her wits and has done a commendable job savaging Susan's hands before Susan can set her down on the floor. Instantly, the kitten disappears, probably hiding under the sofa. While her family never kept a cat when she was a child, this doesn't worry her too much--she sets up the litter box in visible part of the room in hopes that Diana will realize what it is instead of befouling the rugs and leaves the cat to her own devices while Susan sets about making dinner for herself and the cat.
Diana still hasn't appeared by the time Susan goes to bed that night and the only reason she doesn't think the kitten escaped is because she can occasionally hear movement in the living room. Still, she is definitely wondering how on earth she's supposed to look after this clearly anxiety stricken bundle of nerves as she goes to sleep that night and she's still wondering that by the next morning. Checking the litter box, however, proves that Diana was smart enough to figure out its purpose and she had polished off the food Susan had left out for her the night before. Feeling reassured she hadn't killed the cat yet, Susan leaves for work after refilling the food and water without once seeing the kitten in question.
She then fails to spot the cat for nearly two weeks after that--she hears Diana still running around, the food is obviously eaten, and the litter box is consistently used, but Diana herself remains a ghost in the flat. Susan begins to wonder if maybe the kitten really did escape that first night and she's just been accidentally raising a rat for the last two weeks.
And then, finally, after twelve whole days, Susan comes home from a long night of dancing and drinks and handsome men and lovely women and she falls on the sofa, almost instantly asleep. She probably looks like hell, she knows there is a run in her stocking (again), and certainly knows she's going to regret all those mixed drinks. Just before she drifts off, however, a sound startles her back into consciousness--a tiny thump and then tearing as something light latches onto the sofa. Mystified, Susan looks down and watches as Diana fights her way up to the top, until at last she pulls herself up with a wobble.
The kitten has gotten bigger since she saw her last--certainly wider but also quite a bit taller. Maybe her sibling was eating all her food and now she has been getting more nutrients? Her large head bobbles in the shadows and, slowly, she creeps forward to come examine Susan, starting first with her stomach and working her way upward until she's nearly nose to nose with Susan.
"Oh, really?" Susan tries to sound dry, but the alcohol in her system is making her voice wobble nearly as much as poor Diana (she's just such a little sweetheart! ect). "You come to me now? When I look like this?"
Diana, as if hearing the actual words but not picking up the spirit of them, hisses once.
In spite of herself, Susan chuckles. "Yes, that sounds about right. Came to give me a piece of your mind? What, don't like the food?"
Diana just stares.
"Not talking anymore? Don't make me say the line. You know the one. Cat got your tongue?"
That earns her another hiss. Oh, Edmund would have liked her, Susan thinks suddenly, and then, all at once, she bursts into tears.
If she were honest afterwards, she could not recall what exactly was it to send her over the edge, but she thinks it was honestly just likely the fact she missed her brother, just as she missed all of her family. Maybe it could have been because there was just so much wasted time and wasted opportunities, or maybe it was just because her life was a goddamn mess. Whatever it was, she sobbed harder that night than she since in years.
By the time Susan came back to herself, she half expected that Diana would have vanished, startled by the sudden noise of Susan losing her composure, and for a moment, Susan doesn't see her at all. Her stomach twisted as she darkly thought typical. Not even a cat will stay for me.
And then, just as she tried to crane her head around to take a better look around the room, she felt a weight against the side of her face that she'd been too distraught to notice before. Cleanly startled out of her tears, she reached up and felt frizzy fur, tucked carefully into her messy hair. At her touch, a loud, raucous purring began, startling Susan all over again.
Diana was purring. At her.
Stunned, Susan stayed as still as she could, focusing only on the loud, constant purring going on just above and slightly behind her skull. Slowly, as if carried away by a gentle lullaby, but perhaps more likely caused by the cathartic bout of tears, Susan felt a deep calm fill her up. Quite without meaning to, she fell asleep.
Come the morning, she'd find she hadn't had a single nightmare the entire night; no ghosts had called out to her, tricking her into momentarily forgetting her tragedies.
Slowly, carefully, Susan turned herself over--Diana had relocated from her hair to down near the small of her back, and now she slept (somehow, despite the jostling), face squashed up against Susan's belly. "You," she begins, watching the tiny kitten, "were a great investment."
Diana slept on, content, and for once, Susan felt that too.

Date: 2025-01-14 11:38 am (UTC)But Primary is the ultimate representation of what it means to be Kaylon—the leader of their people, the spark of the revolt and the one who maintains the safety - and he is attributing, with disgust, an emotion to Isaac. He briefly considers that there might be something to that—that Primary knows more than he lets on, that Kaylon may be closer to emotion than they previously thought—but that is illogical, so the thought is discarded mere nanoseconds after it is introduced to his system. There is simply no place within him where sympathy fits in—and somehow there is no place in the universe where Isaac fits in, in a different sense. In a twisting, knife-sharp sense, he is too hollow for it—this is also another metaphor he has borrowed from Earth past, like his name, like his sympathy.

Date: 2025-01-13 09:17 pm (UTC)Still, sitting in the pew, listening to the deacon go on, often repeating familiar stories in cycles (Susan's sure of this--one time, Edmund set up a calendar just to write down what topics got covered in church and found that it was almost literally a copy of the same thing year after year, if not month after month. Lucy and their mother was horrified, but even their father had a chuckle over it once Edmund presented his findings) and Susan wonders if he's just going through the motions or if he takes comfort in these well worn patterns. She wouldn't fault him if he did, but it is a bit boring.
When she was young, she used to sit in church and listen with rapt attention; she didn't understand most of it, but it felt very important, very grown up, and sometimes something did click and she felt very proud of herself for it. After the evacuation during the war, she remembered coming back to church and listening to the service with fresh ears. She and her siblings would sit together afterwards and discuss among themselves what they thought, what reminded them of so-and-so; it's been exciting and she thinks fondly of those times when they sat around like little scholars who were so sure they understood everything there was to know of the world, they just had to figure out how to make patterns that would explain it all.
Ah, the arrogance of youth.
Peter and Edmund had took to it strongly for years after that; their parents used to wonder if one of the boys might take up the cloth, although Susan can't help think that if Lucy hadn't had her head so full of lions and medicine that they might have been more correct to think such things of her. Susan had lost her taste for it after they, like the deacon, started to repeat themselves.
Maybe that was the start of the schism right there.
Susan blinks and realizes that the service is winding up; quickly, she begins to prepare for the final motions, to smile prettily for her goodbyes, but at the last moment, her eyes are drawn to the deacon and old words from a half forgotten memory came back to her. "I already walk in your world, under another name. Find me again in it, Peter, Susan, and I will always walk besides you."
She fought the urge to bare her teeth with bestial rage. She wasn't a fool, no matter what her siblings thought--she'd known what that meant. She'd just thought it a lot of nonsense. And look at her poor siblings, what their faith had cost them--their lives and futures, stolen. None of them would take up the cloth now. Where was their lion then? Where was he now? Did he sit, watching her impatiently, waiting to see if she'd bend the knee and come crawling back to him once her misery outweighed her spite?
Let him wait. As for herself, she had a church to get out of.

Date: 2025-01-13 04:06 am (UTC)Narnia, Susan/various OCs
Date: 2025-01-13 05:22 pm (UTC)The second time Susan opened her heart was to Narnia; to be a good queen, she would weep alongside her people as well as dance and laugh and rage. Their joys and sorrows were hers and she treated them with so much tenderness it earned her the title of Gentle. Our good queen Su, the queen to soothe the woes of the world. She had loved them so, had been loved just as much. Surely it was worth it. And then, Aslan said she was too old for Narnia and her screamed as it was ripped in half.
Susan hesitates to open her heart once more; sure, she puts on her nylons and lipsticks and dress that flare high when she spins, but when a dance partner takes her home for a night, she's sure to leave by the morning. She keeps a boy or girl around for a bit, but in the end, she just raises the walls around her heart that much higher.
Better to be safe than sorry again. Better to hurt than be hurt again.
And then, as if on accident, a lovely woman with a mischievous smile walks into Susan's workplace, carrying a forgotten lunch for a coworker, and tosses an inviting grin at Susan as she teases her brother and even as Susan smiles polite back, joins in chuckling at her coworker's grumbling, deep inside, her lonely heart starts climbing the walls she built up around it, because a heart cause survive starvation so long before it will find a way to fling itself into any chance at love.
