Upside-down

The two were walking until Sans got pulled by his sleeve. He opened one eye and looked at a tiny gryphon pointing at something on the wall. Sans turned his head only to see a glittery poster with a robot on it. He opened both eyes and got closer. He blinked a few times in surprise. It was a poster for Metttaon's latest show. A tragic tale of two star-crossed lovers who were kept apart by the tides of fate ANd it looked like it was almost time for the show to start. Frisk looked up at him and he sighed. 

"jesus christ...we've got the best luck, don't we?" Frisk chuckled a bit and he picked her up and set her on his shoulder. They walked a bit and suddenly they were in front of a weird prop landscape with fake stars and a balcony with stairs taking you down from there. A metallic voice started talking.

"OH. COULD IT BE...?" Said a robot peaking from behind the corner. He left himself show and the two noticed the white and light blue dress he was wearing with a lot of puff to it. Frisk spurted and almost fell of his shoulder. Sans was shocked and started snickering at the sight. 

"...MY ONE TRUE LOVE..? AND THEIR BRAINLESS SERVANT..?" Sans gasped and Frisk started laughing louder. Some dumb music started playing and Mettaton started descending the stairs. Frisk and Sans were howling with laughter at this point. Then it got 100 times better....HE STARTED SINGING. 

"Oh my love. Please run away. Human King. Forbids your stay. Monsters must. Live far apart." Frisk fell off Sans shoulder in a fit of laughter and he bent down laughing also catching her by her tail. The two were laughing like they were drunk or something. 

"Even if, It breaks my heart. They'll put you, In the dungeon." Suddenly fake rose petals started flowing from somewhere and that only made things worse as Frisk was rolling with laughter and Sans was using his knees to sustain his weight. They were wheezing. WHAT THE FUCK WAS THIS SHOW?! It looked like someone took second hand and put it with Romeo and Juliet then added Mettaton's shitty acting as a toping on top. Frisk wasn't able to breath at this point. 

"breath pidge!!" Sans said coming down a bit from his fit of laughter. One moment of breathing and they were sent laughing again as mettaton was posing dramatically for effect between the rose petals. She never thought she'd have to go back to a save point because of actual dying of laughter. 

"It'll suck. Then you'll die a lot." At the end of the other two lines Frisk started pounding on the ground. Sans fell to his knees and was holding his stomach. It was clear Mettaton was growing irritated with them at this point. 

"Really sad. You're gonna die. Cry cry cry. So sad it's happening." The song finally ended and Frisk and Sans both started wheezing again. Mettaton looked at them and crossed his arms. 

"OH COME ON. IT WAS A GOOD SONG AND I HAVE NEVER SANG OPHERA!! YOU CAN DO BETTER??" Frisk wiped the tears from her eyes and Sans smirked at the question. 

"i can't..." Frisk was dusting her shorts as she finally set up, still giggling. 

"but the kid can." Sans said nochallantly. Frisk froze. 

"I can what now--"

"THEN GO AHEAD AND SING FOR US, DARLING. I BET YOU CAN'T DO BETTER THAN ME!" Frisk looked at Sans and gestured franatically at him. He huckled and shrugged. She face-palmed and breath in, then out. 

"Fine...Fine...Hope you know about Carmen." The two nodded. Thank god some culture was still well known in the Underground. She took on a serious face. 

"L’amour est un oiseau rebelle
Que nul ne peut apprivoiser
Et c’est bien en vain qu’on l’appelle
S’il lui convient de refuser" Sans spurted and Mettaton's screen went blank as she started singing. Her voice was so different. It came from the core. She was using her breath and vocal chords to their maximum capacity. 

"Rien n’y fait, menace ou prière
L’un parle bien, l’autre se tait
Et c’est l’autre que je préfère
Il n’a rien dit mais il me plait" Metttaon's screen at this point was showing an error. Sans smile stretched as he realized Frisk was teaching that dumb robot a lesson. 

"L’amour! L’amour! L’amour! L’amour!" She almost tricked them that she would hit a high note. 

"L’amour est enfant de Bohême
Il n’a jamais jamais connu de loi
Si tu ne m’aimes pas, je t’aime
Si je t’aime, prends garde à toi!" Her singing was mesmerizing. Even back at his and his brother's house, Sans felt how her singing was magical. But he never expected her to be able to sing ohpera. THAT took quite the lungs and strenght. 

"Si tu ne m’aimes pas, si tu ne m’aimes pas, je t’aime
Mais si je t’aime, si je t’aime, prends garde à toi!" Mettaton started playing a chorus in the background from his screen and an orchestra to acompany her.

"L’oiseau que tu croyais surprendre
Battit d’aile et s’envola
L’amour est loin, tu peux l’attendre
Tu ne l’attends pas, il est là" Sans was staring at Frisk dumbfound. Their eyes met for a second and a small smile could be seen on her lips. That made him blush. He always loved her smile. It was bright and kind. 

"Tout autour de toi, vite vite
Il vient, s’en va, puis il revient
Tu crois le tenir, il t’evite
Tu crois l’éviter, il te tient" The chorus started singing alongside Frisk the last bit, however the high notes at the end made it all worth it. 

"L’amour! L’amour! L’amour! L’amour!
L’amour est enfant de Bohême
Il n’a jamais jamais connu de loi
Si tu ne m’aimes pas, je t’aime
Si je t’aime, prends garde à toi!
Si tu ne m’aimes pas, si tu ne m’aimes pas, je t’aime
Mais si je t’aime, si je t’aime, prends garde à toi~~~!!" Frisk said, the last note being raw and then she took a deep breath. Mettaton scoffed in jealousy as Sans smirked at the robot, making it worse. The robot's screen started flickering red in rage. Sans looked at Frisk. 

"you did great, sweetheart." Frisk was panting but she smiled at him. 

"thaks...-pant- starlight...whew..." Frisk said then she took a few deep breaths and was ok. Mettaton started beeping in rage. 

"WELL! THAT DOESN'T PROVE ANYTHING! YOU'RE STILL GOING TO THE DUNGEON!" Frisk's eyes widened. 

"Excuse me the wha--" 

"WELL, TOODLES!" Mettaton pulled out a remote with a button from behind him. The ground opened underneath Frisk and she was falling, as the ground swollowed her whole. 

"FRISK!" Sans yelled then shot the robot a norrowed look before teleporting down, where Frisk was sitting down, rubbing her head. She didn't have time to take out her wings for that small fall. Sans teleported next to her. 

"you ok there, pidge?" Frisk nodded and gave him a reassuring smile. He sighed in relief. 

"man, one day you'll give me a heart attack.." The robot flew down. 

"OH NO! WHATEVER SHALL I DO? MY LOVE HAS BEEN CAST AWAY INTO THE DUNGEON! A DUNGEON WITH A PUZZLE SO DASTARDLY, MY PARAMOUR WILL SURELY PERISH!" Frisk and Sans both frowned at the robot. They saw a bridge ahead of them and started walking in that direction. It took them to a familiar sight. 

"the colored tile maze made by alphys..." Both Frisk and Sans said looking at each other. Frisk's eyes started changing in panic. Sans smile flattered at the edges. 

"OH, HEAVENS HAVE MERCY! THE HORRIBLE COLORED TILE MAZE!! EACH COLORED TILE HAS IT'S OWN SADISTIC FUNCTION! FOR EXMAPLE A GREEN TILE SOUNDS A NOISE, THEN YOU MUST FIGHT A HUMAN, RED TILES WILL....ACTUALLY...WAIT A SECOND. DIDN'T WE SEE THIS PUZZLE ABOUT A HUNDRED ROOMS AGO BACK IN SNOWDIN??" Frisk's eyes widened realizing they weren't going to give her the description again. Oh she hoped her memory won't betray her now. 

"THAT'S RIGHT! YOU REMEMBER ALL THE RULES, DON'T YOU?"

"I--" Frisk tried to say, but the arrogant star dressed in a dress was having none of it after their laughter up above them and the way she put him to shame with her angelic voice. HE was the star. HE was the best. HE was a narcissist. (I'm pretty sure you don't actually know what that is metta..but you do you...i'm the one writing this fanfic after all :/)

"GREAT, THEN I WON'T WASTE YOUR TIME REPEATING THEM!!" Mettaton said clasping his hands together. Sans put a hand around Frisk who was shaking at the thought she had to cross that maze. 

"you are SICK! you piece of metal.." Sans snarled. Mettaton didn't care. 

"OH AND YOU BETTER HURRY, IF YOU DON'T GET THROUGH IN 30 SECONDS YOU WILL BE INCINIRATED BY THESE JETS OF FIRE." Frisk looked behind her and shrieeked. 

"OH AND I AM TAKING HIM!" More confetti binded Sans as he was picked up by the robot. 

"I MAY BE A KILLER...BUT I WON'T KILL ONE OF MY KIND! AHAHAHHAH HAH HA.....HA...OH, MY POOR LOVE! I AM SO FILLED WITH GRIEF I CAN'T STOP LAUGHING!! GOOD LUCK, DARLING~~" Sans tried to struggled to get out and a star appeared glimmering next to Frisk. She saved and the counter started. 

"FRISK!! shit--" Sans said. Frisk was already walking through the maze. The first time she died was at the 20 seconds mark when she was eaten alive by piranha. Sans watched in horror as the water turned to red and looked away. Another LOAD. 

The second time, she was zapped by a thousands high voltages. Sans couldn't look at all that energy went through her body and pratically turned it to charcoal. Another time she died by fighting a monster who imapled her with a sword and so on and so forth. It had been 15 runs and Sans couldn't get out of the robot's stupid confetti. Frisk was so close to winning. 5 seconds left. She was near the end. 

4, just a few tiles left. 

3, she could see the finish line. 

2, it was within her reach. 

1, she was 2 tiles away. 

0. she was on a line of green tiles right at the end of the maze. Sans eyes widened. No...NO NO NO SHE WAS SO CLOSE!! SHE CAN'T DIE AGAIN!!

"OH MY....I'M SO SORRY BUT IT LOOKS LIKE YOU'RE OUT OF TIME...HERE COME THE FLAMES, DARLING!" Frisk looked at the robot unpahsed then looked at Sans. A red glimm passed through her yellow eyes. Sans calmed down a bit. 

"THEY'RE CLOSING IN!" Mettaton announced. Frisk looked confused. The flames were moving slower and slower. 

"GETTING! CLOSER! OH! MY!" Frisk saw how the flames stopped close to her, but far enough not to hurt her. She had a feeling...they won't hurt her. 

"ANY MINUTE NOW!!" But they stood there awkwardly. Sans was confused. Frisk wasn't surprised by this. She at one point put 2 and 2 together. Alphys and Mettaton worked together. Mettaon fidgeted then coughed. And right as he coffed Frisk took out her phone. Mettaton's screen went blank and she waited a few seconds. Suddenly, Alphys called. She answeared immediately. 

"Watch out! I'll save you--" Frisk didn't let her finish. 

"No need." She said coldly. She took out her wings and fluttured them around. The wall of fire was gone. She took out her claws and sliced the machines holding the fire wall so they couldn't respark it. Alphys and Mettaton were silent. 

"OH NO! HOW COULD THIS HAPPEN?! FOILED BY THE BRILLIANT DOCTOR ALPHYS AND HER FRIENDS!" Suddenly Mettaton stopped. His screen lit a dangerous red. 

"IF I CAN'T TOUCH YOU DARLING, I SHALL USE THE HUMAN AS BRIBE!" Alphys was silent. 

"T-that w-wasn't supposed to h-happen!" Alphys said. Sans was pulled close to the killer robot. 

"W-wait M-Mettaton!!" Frisk however was already behind Mettaton. Sans smirked. 

"sorry bud...that won't happen on her watch.." He said with a nonchalant shrugg. The confetti and his dress were ripped to shreds and Frisk had her claws on his arm ready to cut them. 

"What make you think...i will allow you to hurt me? And more importantly...him?" Sans shook his head as he teleported in front of the robot. Alphys and Mettaton were silent. 

"Y-yeah mettaton! G-Give up already!! Y-You'll never be able to defeat us! N-not as long as we work together. Your puzzles are over! " Alphys said trying to muster up some courage. Sans grin stretched a bit. He must have put two and two together as well when Alphys called and the wall was closing in. 

"PUZZLE...? OVER..? ALPHYS, DARLING, WHAT ARE YOU TALKING ABOUT..?" Mettaton was however shaking, as the cling of metal anaginst Frisk's reinforced claws was telling them. Mettaton then stared at the place Frisk just was in. 

"OH...BUT...DID YOU FORGET WHAT THE GREEN TILES DO...? THEY MAKE A SOUND..THEN YOU HAVE TO FIGHT A HUMAN. WELL DARLING...THAT HUMAN...PART ROBOT OR NOT...IS ME!!" The robot turned around and lounched at her hands gripping tight around her neck. Sans caught her phone and the two were going down towards the floor when the encounter saved them. Frisk's heart was glowing now. Mettaton sitting in front of her. Sans was holding her phone. 

"S-Sans y-you have to--"

"save it alph...you'll have the right to talk later..now..? we need frisk to get out of this alive." 

"THIS IS IT DARLING...SAY...GOODBYE!!" Alphys then yelled from the phone. 

"FRISK!" They all stopped. her crimson red eyes turned back to honey yellow as they all stared at the phone. 

"T-there's one last thing i installed o-on your phone! You see that yellow button..? PRESS IT!" Frisk's eyes lit up. 

"did you just say...yellow..?" Alphys got excited. 

"Y-yes! It will make your soul y-yellow!!" Frisk thought about it for a second. 

"That won't work on me...Let's do it..manually!" She took out her wings. They were now a golden hue as the heart turned around and was yellow. Sans eyes widened. He knows humans can turn souls different colors and use them for their attacks and games but...a monster...heh. This girl was full of surprises. Mettaton backed away a bit. She started shooting little magic attacks from her soul. Alphys said it should help. Mettatons screen went blank for a second then with a very fake act Mettaton started shaking. 

"OHH!! OOOOHHHH!! YOU'VE DEFEATED ME!! HOW COULD THIS BE, YOU WERE STRONGER THAN I THOUGHT, ETC." Frisk frowned at his two dollar act. 

"WHATEVERRRRRRR~~" He said leaving and he vanished alongside the encounter. 

"HEY HOLD UP! I DIDN'T FINISH BEATING YOUR SORRY AS--" Sans put a hand on her shoulder and she stopped. 

"better pidge...?"

"y-yeah..." She said looking down. He sighed and pulled her in a hug. 

"jesus kid, you've got me worried sick...how many...?"

"...almost twenty i think..." Sans sighed and let his head rest on hers. 

"you ok...?"

"my whole body kinda hurts...but i'll be fine..." Sans nodded. 

"ok now...as for you, alph.." Sans said and the human scientist screetched.

"Y-y-yes Sans...?" He norrowed his eyes. 

"Why have you been faking it the whole damn time?!" Frisk said, a bit too loud. Sans put a hand on her shoulder. 

"calm now, sweetheart." She growled but scoffed and let the human explain themselves. 

"I-I'm sorry...I-i swear i meant no harm i-it's just...i..i wanted to feel important...to feel better about myself..i thought i-iif i'd add myself to your story....i-i could...y-you know..." Frisk froze and immediately all the rage she felt for the human melted. The looks she saw weren't dangerous...it made her feel danger because she was desperate...just like Frisk had been a long time ago...Desperate...depserate for something...anything. 

"i-i'm so sorry..." Frisk said. Both humans were silent. She looked at the phone lost. 

"y-your eyes weren't dangerous...they were desperate...for something ANYTHING to cling onto....y-you...wanted to fix something..." Alphys was silent. Sans eyes widened. 

"H-how did you know..?" Alphys asked. Sans froze. 

"because she had the same look in hers..." Frisk looked at Sans ans smiled softly. His smile was sad. 

"i'm sorry alph...i just blamed you because..."

"I-i know...well...N-now that the cat i-is out of the bag i-it's clear that mettaton wants your soul..." Frisk chuckled. 

"You thnk..?" Alphys laughed awkwardly. 

"i-i'll help you get through the core. We're not that far and we can get there soon..." Sans eyes norrowed a bit. Frisk looked at Sans hopeful.

"oh no no no! don't you dare think you're going to keep going today sweetheart. hell no. look at yourself. you are about to fant from exhaustion." Frisk puffed. 

"no i'm not." Sans face-palmed as he saw Frisk's knees were buckling. Alphys hummed. 

"H-he is right! Monsters need rest to surivive, unlike humans.I-i can't beging to imagine how much magic you have consumed s-so far with all the stunts you pulled."

"and dying." Sans added more like a grumble. Alphys sighed, not hearing him. 

"W-we shall do this tomorrow. MTT Resort is just up a-ahead. G-go ahead and rest."

"Thank you..and Alphys..?" Frisk said. Alphys hummed. 

"i forgive you." Silence. 

"T-thank you.." Alphys said more like a whisper as the call ended. Sans sighed. 

"you're far too nice, sweetheart." Frisk smiled. 

"Sometimes, kindness is enough!" They walked and climbed a huge flight of stairs which left Frisk almost breathless. She was hungry and tired. And Sans must have noticed because he offered to carry her. She refused. But he did insist in her eating something before they get a room. She sighed and agreed just as her stomach rumbled. She blushed in embarrassment and Sans snickered at her. They passed the two guard that had a bromance eating ice cream from that nice-cream guy she met. Nick, was his name if she rememebered well. She saved as they finished climbing the flight of stairs and met with a fancy looking building like it was taken straight out of a broadway type of movie. Frisk chuckled at the sight. 

"looks like something fancy from the surface, eh?"

"definitely!" Sans then outstratched his hand like a gentleman. 

"may i take this fine lady out for dinner in this marvelous establishment..?" Frisk snickered then acted like a lady. 

"why, my dear gentlemen, you shall~" Sans winked at her and she could feel herself blush. 

"well, mi'lady, let's go this way. i know a shortcut." And with a flare of his magic they were inside the reastaurant. Decorated with a fancy chandelier and tables with more forks and knives then she's ever used in her life. Quite the silverware. The two set down in a corner, next to a bush of beautiful red flowers. Frisk looked at the flowers and squealed in delight, not loud, even if they were the only ones inside the place. 

"oh my god! These are Red Azaleas! Such beautiful flowers!! i haven't seen any red...ones....o-oh.." Frisk said blush creeping up on her face as Sans looked amused at her. 

"'s fine kid..however..i brought you her so we can have a serious talk..ok..?" Frisk nodded. 

"ok...let's talk." Was it just her..? or did the room get chiller. The dark look on Sans face said that it wasn't just her. And she was in for quite the talk.
