You're Not Stupid - A Fionna and Cake Fanfiction
((FIONNA AND CAKE SPOILERS MY DUDES. YOU HAVE BEEN WARNED!!!
This is written to be completely platonic/familial, and if you think otherwise, I'm gonna have to take your kneecaps, okay?
Anyways. This is how I wish that one scene went in episode 8. You know. The one with Fionna crying in the most heartbreaking way ever. Please enjoy pain, tears, and Simon being very soft. I told y'all I have no self control. Let me know if you enjoyed it, and maybe I'll write more ;D
Enjoy!))
“BMO was wrong!”
“And so was Fionna! We blew it, we blew it!!”
The sound of Cake’s furious yowling as the cat smashed bits of the dilapidated lab equipment echoed in Fionna’s head. This was her own fault. Everything, as always, was her fault.
Her friends at home knew her as flighty. And now, all the people in this terrible, abandoned lab, knew her as a failure, too. She was no adventurer, no knight in shining armor, and hell, not even a good friend. On top of all of that, she was a liar, too.
No one knew that Fionna had the crown in her backpack. She didn’t dare tell Cake, and especially, not Simon. In the days that she had traveled with the gentleman, Fionna had quickly learned that Simon was willing to do anything in his power to keep both her, and Cake safe- even if it meant putting on some cursed object that would render his brain jelly in a matter of minutes, perhaps.
She didn’t want to see Simon deteriorate, and act as he was in those miserable tapes. Delusional. Insane. Depraved. No, she couldn’t do that to him. She couldn’t. She couldn’t tell him about the crown…!
“My office supplies!” BMO’s high little voice rang out as Cake proceeded to push every object on the desk onto the floor.
Fionna’s cheeks flushed red, and tears stung her eyes as the situation escalated. A lump formed in her throat, and before she knew it, she was running out the doorway and onto a balcony as guilt sunk its teeth into her like a viper.
She hadn’t even noticed that Simon’s head had whipped to look in her direction, and that he had immediately noticed that something was wrong.
Once she was in the open air, she let out a couple of heartbroken sobs as bubbly tears dripped down her burning cheeks. She could barely see the dead and abysmal landscape as the tears kept flowing.
However, she wasn’t alone out there for long.
“Fionna, it’s okay,” came Simon’s calm but concerned voice from behind her.
Immediately, Fionna shrank down onto the ground, turning away from him in shame as she pulled her knees up to her chest.
“Simon, I’m so stupid! I’m sorry,” she sobbed. “Why did I think I could do this?!”
Why was she so stupid? Why did she always mess everything up? And on top of that, why was she still lying to Simon and Cake about having the crown?
Her shoulders shook as she buried her face in her hands, her breath coming in short gasps and hiccups.
She felt an arm wrap around her, and then another.
“You’re not stupid,” Simon murmured.
Fionna froze for a moment. She didn’t feel like she deserved the kindness that she was being given, but truly, she couldn’t help but give in to it. Regardless of being an adult and feeling like she needed to be grown and handle everything on her own, she still needed support. She still needed someone to make her feel like everything was going to be okay. She needed Simon.
She needed him never to put that horrible crown on his head. He didn’t deserve it.
Fionna melted into him, and threw her own arms around him, burying her face in his shoulder. The lingering smell of coffee on his clothing was comforting, and reminded her all too much of home. She was at a loss for words as all her worries and concerns tumbled out of her in a torrent of tears, which collected on Simon’s suit jacket.
“It’s going to be okay, Fionna. We’re going to figure something out,” the man spoke softly to her as he gently rubbed her back. “It’s okay.”
But would it be okay? Would it really?
After some time, Fionna managed to collect her emotions, and tuck them all back inside of her where they belonged. When she pulled back from Simon, the man wiped away her tears with his thumbs.
“T-thanks for that, Simon,” Fionna hiccupped. “Sorry, I probably got snot all over your jacket.”
Simon shook his head and smirked.
“Oh, I could have worse things on this jacket,” he chuckled.
Simon smiled at her and tilted his head as he cozied himself up against the wall of the balcony.
“Are you feeling any better?” he asked.
Fionna nodded and wiped her nose on her sleeve, sniffling.
“Y-yeah. You know, Simon, I get why that vampire girl turned out so bad in that one dimension. You’d…you were a really good dad. I can tell.”
The tender look in Simon’s eyes said more than words ever could convey the moment those words left the girl’s mouth.
“Thank you, Fionna,” he said, clearing his throat. “I appreciate that.”

WIP - Finding Your Missing Problem
So doing that one post earlier today got me thinking...
What if Marceline actually FINISHED singing 'I'm Just Your Problem' instead of choking at "Why do I want to...?"
As in, what if we, and more importantly Bonnie, heard what Marceline REALLY wanted? XD
---
The growing lights become a crescendo as the sealed doors of the Door Lords practically explode in a cloud of glimmering sparkles rising up before descending down into the canyon.
And at the center of it all, bathed in a shower of shimmering fractals of light in front of the now-open gateway, floats Marceline the Vampire Queen.
“Oh my glob Marceline! That was AMAZING!” yelled Finn the Human in abject awe as he ran up to the entrance to look up to the floating vampire.
“Yeah! That door said we needed a band, but you busted that thing open all on your own!” Jake the Dog added as he also ran up to join his younger brother.
“Yes! You have proven yourself far superior to our lacking musical talent.” Added BMO.
But Marceline didn’t seem to hear them, or even register what she just accomplished.
She was breathing heavily, her face now drenched in sweat from an exhaustion that wasn’t physical. Her axe that she once held tight as she played her song was supported only by its strap over her shoulder, her arms now hanging limp at her sides. Even her normal energetic floating was now entirely still.
And she wasn’t looking at Finn, Jake, BMO or even the brilliant shower of lights falling around her.
Instead her gaze was locked squarely on the pink-haired, pink-skinned gum princess sitting shock-still on a rock. Whose own gaze was locked squarely back at her. One wide-eyed pair of eyes staring right into another.
Then the pink girl got to her feet.
The princess walked forward in a slow, almost uncertain pace and the vampire queen drifted slowly downwards.
All the while their shared gaze never breaking.
“Come on Princess! Let’s go get our… stuff. Princess?” Finn spoke up, only to trail off as the princess walked right past him without so much as an acknowledgement.
It seemed in this moment, Bonnibel Bubblegum was focused just as absolutely on Marceline Abadeer as the other was on her. Completely unaware and uncaring of anything except each other.
After what was in reality just a few moments but which probably felt like an eternity to the pair, Marceline’s feet finally came to rest on the ground and Bonnibel’s feet came to a halt. The two now directly facing each other so close that the princess’s crown was bumping into the wide brim of the vampire’s hat.
Both of their gazes still locked firmly on the other’s, both of their faces in an unreadable expression, though for entirely different reasons.
Marceline’s face was an unreadable mess of emotions. Shame, longing, guilt, nostalgia, anger, affection, fear, and so many others.
Bonnibel’s face by contrast was an unreadable blank. A complete neutral seemingly devoid of anything.
The pair continued to stare into each other’s eyes for a couple more moments as the shower of lights fell around, which must have felt like another eternity for them. Entirely unaware and uncaring of anything but each other.
Until…
“Bonnie,-MMPH” Marceline spoke while Bonnibel acted.
Bonnie lunged forward, smashing her lips in Marcie’s own, so hard and so fast she knocked her own crown off on Marcie’s hat.
And despite any surprise, it was only after the barest of split-seconds of hesitation that Marcie was smashing her own lips back into Bonnie’s JUST as hard.
Mouths opened, teeth banged together, tongues met and hands began to hold fast to each other as Marcie and Bonnie KISSED.
----
There will certainly be more XD
(To be clear, I have no intention of posting full fics here. Completed stories will still only be going up on my AO3 page.)

Would you all read a fanfic on an AU of Simon Petrikov from Fionna n Cake/(Adventure Time). The AU fanfic will be regarding around my recent development of Wildmon (as seen in previous posts.) It’s about Simon going through drawbacks and eventually heading out to the Heart of the Forest to find himself. His true self.

It’s Free Real Estate
Summary: The backstory for how Marceline got ahold of PB's sweater. (Missing scene with slight canon divergence, Marceline and PB are in a relationship.)
Warnings: none, this is just fluff
I wrote this as a gift for my little sister's bday. This is based on the white sweater with red, yellow, and blue stripes that both Marceline and PB wear later on in the series: https://images.app.goo.gl/UFeAAiBYjb3M8FJq7.
Thank you to @nebula-gaster for beta reading, I appreciate it!
Read it on ao3: https://archiveofourown.org/works/46226977
Or under the cut:
Marceline blinked slowly, the ceiling coming into focus above her. It was higher than her own ceiling, and she recognized the familiar arches right away. That was right, she had stayed over last night.
She and Bonnibel had finally started hanging out again. She still wasn’t sure if they were really dating or not, but they could take things slow. They both had plenty of time, and maybe the reason things hadn’t worked out the first time was because Marceline had rushed things.
Whatever they were, last night Bonnibel had invited her to watch a movie, and she had accepted. Then they had stayed up talking all night and late into the morning—late enough for Marceline to fall asleep, while Bonnibel went off to start her day. She was probably exhausted, but Marceline had seen her stay up for four days in a row before her brain finally crashed. She would be fine.
Marceline stretched, then finally rolled out of bed. Bonnibel’s blanket was soft and fluffy, and she kept one wrapped around her as she looked around. Her jacket was still lying on the chair where she had dropped it last night, but she had a better idea.
Marceline crept over to Bonnibel’s closet and opened it up. She knew that Bonnibel had some nice clothes, and she wouldn’t miss one sweater. Most of Bonnibel’s closet was pink or purple, but Marceline wasn’t after that.
At the bottom of a thick stack of sweaters, she finally found something she liked. A chunky knitted white sweater with thick red and yellow stripes across the chest, and some blue ones on the sleeves. She felt the material, and it was even softer on the inside than it was on the outside.
Marceline tossed the blanket back on the bed and put the sweater on. It was oversized and hung down her legs almost far enough to be a dress. She glanced down, adjusting the neck of the sweater so that it hung off of one shoulder. Even if she couldn’t see herself in the mirror, she could still tell that the sweater looked nice on her.
The door opened. Marceline turned invisible, hoping the sweater had changed with her. When Bonnibel stepped in, she sighed and reappeared again.
“Hey, what’re you doing back?” She asked, floating a bit closer to Bonnibel. “Is the kingdom finally able to run itself?”
Bonnibel didn’t look surprised to see her. “Unfortunately, no. Breakfast Princess and Wildberry Princess are here for afternoon tea. I need to change,” Bonnibel said, gesturing to her open lab coat and worn-out pink flannel. She glanced up at Marceline and squinted. “Is that mine?”
“Yeah. You mind if I borrow it?” Marceline asked, already going back down to the ground in case she needed to take it off. “It’s really soft.”
“Why?” Bonnibel saw that Marceline was confused, so she explained herself a bit more. “I mean, you have your own clothes. Why do you want mine?”
Marceline opened up the hidden drawer inside of Bonnibel’s closet, and pulled out the old band t-shirt she had given Bonnibel back in the day. “You’ve got one of mine.”
Bonnibel blushed, and she grinned. Too easy. She still had the sweetest pink flush Marceline had ever seen. She had just woken up, so she was hungrier than usual. She shook her head a bit, getting those thoughts out of her head. Feeding from Bonnibel was an emergency measure only.
“You can take it.” Bonnibel looked away, rubbing her arm. “And if… you want to trade more clothes, just let me know.”
“Thanks Bonbon,” Marceline said, letting her feet lift off the ground again.
She moved around Bonnibel and grabbed her jacket from the chair, draping it over her shoulders. She hadn’t expected to stay overnight, so she hadn’t brought her umbrella. She would need to turn into a bat and hide to fly back.
“I’ll go through your closet another night. I should probably head home and get some breakfast.”
Bonnibel nodded, glancing between Marceline and her closet but not moving yet. “Yes. I have to go before the others get suspicious.”
“Okay, cool.” Marceline tugged on her jacket, floating a bit closer to Bonnibel. “I’ll see you later then?”
“Goodbye, Marceline.” Bonnibel smiled at her.
“Bye.”
Marceline swooped in and kissed Bonnibel’s cheek, then flew away before Bonnibel could react. She transformed halfway into her bat form, using her wings to make both the curtains and windows in front of her open wide. Marceline curled up underneath the coat, her face burning as she flew away from the castle.

my the outer gods rot my brain with an idea so wasteful..yet exciting.
If "The Scholar And The False Prophet" had a soundtrack by the one and only ( me ) A 1 hr playlist, nothing too grand, just a compiled list of songs that closely fit with the vibes of the story...closely
If you want to read, the story is pinned on my profile :)

It’s been a week since he escaped the crowns influence, and Simon is still playing the role of both warden and prisoner to himself. Integrating into this new, semi-hostile society is difficult, and so he chooses to isolate, watching others move about their lives from afar.
Of course, his solitude doesn’t last long.
