Undertale: Fay Route

Frisk was still wrapped in the provided blanket and eating some food Fay had bought earlier. She was right in saying they would need it. As they ate, Frisk watched in mild amusement as Fay spun around one of the "bars" of the cell. Or rather, running around one. Frisk suggested that they simply leave, but Fay shook her head. It would seem she had a plan. She was still spinning and running about when Papyrus came in to check on his "prisoners". Fay stopped spinning and ended up on the outside of the cell. Looking over to their peppy captor, Fay smiled and launched herself at the tall skeleton. Luckily, Papyrus caught her and held the girl in his arms as she hugged him in greeting.

"Hey Pappy!"

"UM... HELLO HUMAN! I AM FLATTERED YOU ARE SO EXCITED TO SEE ME, BUT WHY ARE YOU OUTSIDE OF YOUR PRISON?"

"Hmm? Oh! I am aren't I! Eh... It's fine bruh... S'not like I left or anything...Right?!"

Before Papyrus could answer Fay's comment, Sans walked in after Papyrus.

"so you seriously caught them? i'm impressed bro... wait, where's the other one-?"

"SANS! Welcome to the party!"

"THERE'S A PARTY?! WOWIE! WHERE?"

"Right here! It's a 'Papyrus captured the humans' party! CONGRATULATIONS!"

Fay smiled widely and started clapping enthusiastically. As Papyrus spoke to the girl, Sans walked over to Frisk with a questioning look. Without looking, he pointed to Fay and raised a brow in a silent question. Frisk smiled but only shrugged their shoulder. They had no idea what Fay was doing, but she seemed happy and was having fun. Turning their gaze back to the short skeleton in front of them, Frisk waved in greeting. Sans nodded back with his eternal smile.

"How do you put up with Fairy over there? She seems to have a screw loose..."

Frisk didn't answer but simply snickered at Sans. Raising a brow, Sans was about to ask what was so funny when he felt a presence behind him.

"Well that's just mean. I don't say anything mean about you behind your back."

With a slight jump, Sans turned around to find none other than Fay looking at him with a close eyed smile. Sweating a bit, Sans took a step back to distance himself from the girl. Unaffected by this, Fay skipped into the cell and leaned over Frisk.

"Join da party Frisk! Common~!"

Frisk giggled at Sans then turned to Fay and nodded. Holding their arms up and making grabby hands, Frisk silently asked Fay to pick them up. Fay rolled her eyes but picked up the child and hefted them onto her back.

"You are getting so lazy Frisk. You're gonna get fat at this rate!"

Frisk pouted and shook their head 'no' while crossing their arms. Fay laughed and walked out the cell.

"I'm only kidding. Still, I spoil you too much. I'm a horrible sister!"

Fay acted dramatically and put the back of her hand to her forehead. Frisk laughed and playfully hit Fay's arm. An action to which she pretended to be hurt and slowly started falling to the floor.

"I'm melting! Oh what a world, what a world! If only my brother weren't so cruel! Where did I go wrong?!"

Now on her stomach, Fay pretended to be dead but couldn't hide her laughter. Frisk was sitting on her back shaking their head humorously. Papyrus quickly ran over having seen Fay on the floor.

"OH NO! WHAT HAS HAPPENED TO THE TALL HUMAN?!"

"it would seem she just couldn't stand it. i guess she just couldn't handle the gravity of the situation. "

Frisk and Fay both broke out into laughter while Papyrus' eyes widened in annoyance.

"REALLY SANS?! NOW IS NOT THE TIME FOR YOUR SILLY PUNS! THE HUMAN COULD BE HURT!"

"Good one Sans... Heh, I'm fine Papyrus. Just playing~ Hey, when is this 'unding' person showing up?"

"UNDYNE? OH! I JUST CONTACTED HER! BUT SHE DIDN'T PICK UP. IT SEEMS THE GREAT PAPYRUS WILL HAVE TO CARE FOR YOU TWO ANOTHER DAY!"

As Papyrus said this, he posed and seemed to sparkle. Stifling a laugh, Fay looked up at Frisk and grinned.

"You think you'll be okay to sleep here, little brother? I don't want you getting sick... Hmm... Papyrus? Can you please let Frisk sleep in your house. It's probably safer and warmer."

"LITTLE BROTHER?! OH SANS! THEY'RE SIBLINGS, JUST LIKE US! OH?... HM.... HOW ABOUT THIS! THE GREAT PAPYRUS SHALL GRANT A TRUCE BETWEEN US, BOTH OF YOU CAN SLEEP IN OUR HOUSE IF YOU TWO PROMISE NOT TO ESCAPE US!!! I'LL HAVE MY EYE ON YOU SO NO FUNNY BUSINESS ALRIGHT?"

Papyrus smiles to himself then holds out his hand to shake on it. Fay gives a thumbs up from where she is still pinned to the ground and Frisk smiles. Nodding, the child reaches out and shakes hands with Papyrus to seal the deal. Frisk mumbles 'We promise' then quickly climbs off Fay's back. Papyrus' smile only grows as the humans agreed to his terms. After all, he couldn't let them be in bad health when handing them over to the king!

"EXCELLENT!!! WE'LL ALL HAVE A 'HOSTAGE SLEEPOVER' SANS!"

"you should be grateful my awesome bro is so generous. be nice and polite and me and pap will worry about the rest."

"YES, WE CAN HANDLE ALL THE OTHER STUFF-- WAIT... THAT WAS A PUN WASN'T IT?!"

Sans just shrugs his shoulders and Papyrus rages. Fay smiles to herself and climbs to her feet, now free from Frisk's weight. This was going quite well and she was glad that everyone was in a good mood. Frisk went over to Papyrus to try and calm him down as he scolded Sans. Fay just kept back and watched everything with a warm, yet slightly sad smile. After a moment, Papyrus finally calmed down and picked up Frisk again. Letting out a loud laugh, the skeleton leapt through the door while carrying Frisk on his shoulders. Giving an empty giggle, Fay shook her head and looked over to Sans.

"You're all too nice..."

"my bro is practically a bleeding heart-"

"It wasn't a compliment, unfortunately... Let's go before they come back for us..."

Sans took a side long glance at Fay as she stared out the door with a weak smile. Narrowing his eyes, Sans walked up next to Fay but said nothing. Fay grabbed onto the bottom corner of Sans' jacket and started walking. Sans raised a brow at this but walked along side Fay. Sensing his unspoken question, Fay laughed.

"You are escorting the prisoner to her new holding cell... I can't run away if you're "holding" onto me..."

Sans gave a breathy laugh and "lead" Fay to the house. Once at the door, Fay let go of the jacket and rocked on her heels as Sans went in first. Following after him, Fay looked around the house in mild fascination. Frisk was sitting on the couch and Pap was in the kitchen, most likely making spaghetti. Walking over to Frisk, Fay plopped down next to the child and smiled. Sans went to check on his brother in the kitchen leaving Fay and Frisk in moderate privacy. Leaning over a bit, Fay smiled and nudged Frisk playfully.

"If you're still awake later, you can ask whatever questions you need to. Just make sure these two are asleep first, k?"

Frisk nodded and nudged Fay back, which started a mini shoving war between the two on the couch. By the time Sans came back out, Fay and Frisk were laughing and struggling to knock each other over. Sans chuckled and sat down on the floor at the foot of the couch. Fay let Frisk shove her and she fell over. Now laying on the couch, Fay squirmed to get comfy and stared at the single sock on the floor by the TV. She paid no mind to anything else and just watched the sock intensely.

"i don't think staring at it will do anything Fairy..."

"I'm making sure it doesn't come to life or burst into flames... I think it moved earlier... I'm not taking any chances with spontaneous evolution..."

"maybe it's a ghost..."

"It's not... The only ghost left without a physical form right now is Napstablook... And they still have to run their families snail farm..."

Fay mumbled as she said all this, but it was still clear enough to be heard. Frisk smacked the girl's head and glared at her. Sans on the other hand looked at Fay with wide eyes.

"and how do you know that?"

"We met Blooky back in the ruins..."

It was obvious that no one believed that. Hell, Even Fay didn't find it very convincing. Keeping her gaze on the sock, Sans tensed up and glared at Fay.

"who do you think you're fooling here Fairy? i'm not a bonehead."

"Technically you are. But honestly, I guess I'm fooling everyone at this point... Not that I'm trying hard~"

At this, even Frisk tensed up and stared at Fay. Breaking her gaze from the sock, Fay smiled at Frisk and Sans. Looking to Frisk and giving a wink, Fay continued.

"Ain't that right 'Legendary Fartmaster'?"

"Fay."

"Hey~ He technically met the criteria. Isn't he always the first to notice anyway? Actually, the only one to notice really... So what's the harm? I'd rather him not attack me thanks~ And you're safe anyway!"

Frisk glared at Fay disapprovingly and shook their head. It wasn't like they could stop her now, she said too much. Sans watched the two with calculating eyes. He honestly was more worried about Fay. He had no notes even mentioned a second human, let alone a overly suspicious female. There were a bunch about Frisk that seemed to go back many timelines. Sans even had vague memories of the child. Another thing he had nothing of, of the girl in front of him. Sans instinctively trusted Frisk, but Fairy here was obviously hiding something. Stiffening when Fay turned her gaze to him, Sans flashed a worried glance to the kitchen.

"We're not here to fight Sans. We all want the same thing, a happy ending."

"Who are you Fay?"

"Wrong question~ Oh hey! Food's ready!"

"I HAVE FINISHED MAKING OUR MEAL HUMANS! I THE GREAT CHEF PAPYRUS HAS MADE SPAGHETTI! THE GREATEST OF FOODS EVER CREATED AND MADE BY THE BEST CHEF IN ALL OF THE UNDERGROUND, ME!"

Fay clapped merrily as everyone gathered around the table to eat. With a plate of spaghetti in front of everyone, Fay's smile quickly faded. Looking at Papyrus, Fay frowned. He was already eating the food while Pap just stared at it. Frisk had a fork full hovering in front of their mouth. They were trying to muster up the determination to eat the substance that Papyrus insisted was food. Letting out a sigh, Fay quickly caught everyone's attention.

"I'm sorry Papyrus... But... I'm not hungry at all. My stomach isn't feeling too well and tomatoes aren't very good for a human's upset tummy... I'm so sorry... I really wanted to try your great food too! Look! It sparkles and everything!"

Fay motioned to the spaghetti for emphasis. It really was sparkling... But that was entirely due to the glitter. Still frowning, Fay looked to Pap with sad eyes. Papyrus was frowning now too.

"OH NO! ARE YOU SICK HUMAN? IT'S OKAY IF YOU CAN'T EAT RIGHT NOW. WHEN YOU GET HUNGRY, I'LL MAKE YOU SOME MORE, OKAY? I ALSO HAVE PLENTY OF LEFT OVERS! WORRY NOT HUMAN. YOU WILL STILL GET TO TRY MY GREAT COOKING!"

Fay flashed Pap an apologetic smile and got up from her seat. Pushing her seat back in, Fay gave a slight bow to everyone. Sans was slightly impressed with how Fay handled and avoided the situation. She boosted his brothers ego while managing to get out of eating the inedible pasta. Frisk however was not so impressed. Actually, they were quite worried and annoyed. Thinking back on it, Frisk couldn't think of a single time they saw Fay eat anything. It has been almost four days now! Watching Fay leave the kitchen, Frisk tightened their grip on their fork and huffed in anger. This caught Sans' attention.

"what is it kiddo?"

"Fay didn't eat..."

"i noticed that bud. what the big deal?"

"YES, SHE DID SAY HER STOMACH WAS IN PAIN, SO WHY ARE YOU ANGRY?"

"She hasn't eaten in almost four days..."

This caught everyone off guard. Papyrus looked out of the kitchen in worry and Sans narrowed his eyes. This was definitely not normal human behavior. Looking over to Frisk, Sans asked the obvious question.

"hey, aren't humans supposed to eat every day?"

Frisk nods and frowns. Sans goes silent while he thinks to himself. Papyrus however is unable to keep his thoughts quiet.

"WHAT HAPPENS IF YOU DON'T EAT EVERY DAY HUMAN?"

Frisk went silent and hid their face behind their bangs. Seeming to get what the kid was getting at, Sans answered for Frisk.

"they die Pap..."
