Falling Down Slowly... A Undertale Love Story (UT Sans × Frisk)

The Knowledge That Doubts Us...

Sans waited for Frisk to wake up... But she didn't... He wasn't worried until it had reached 4 in the afternoon... He'd known the Kid to sleep in till the afternoon before, especially on nights they had struggled with it... But it had never gotten this bad... Sans climbed the stairs to their room and looked into the dark room to see Frisk still curled up in the blankets... "Umm... Hey Dollface... It's time to get up..."...

But there was no response...

He walked over and tried to shake them awake now, "Hey Kiddo ya realise no matter how much sleep ya get y'all never get as tall and Paps'... Right... Come on Kid, I've been a lazy 'bones' but this is kinda taking it to a whole new level...", still no response.

Sans went to feel Frisk's head, her temperature had spicked once again. Suddenly all of the shaking and having only eaten Paps' spaghetti for over a week, hit Frisk waking her up with a gut wrenching punch to the stomach. She ripped the blankets and jumped up, almost kicking Sans in the face, as she ran out of the room towards the bathroom, "Ah Sans, You Finally Got The Human Out Of Bed!", Papyrus yelled from the living room as Frisk ran into the bathroom, the sounds of her nausea filled the house. Papyrus simply looked up at his brother with the neutral face of displeasure, (-_-), "I'll Make The Human My Special Spectacular Get Well Spaghetti! She Will Suerly Feel Better With That In Her Belly!!!", all Sans could do was roll his eyes as Papyrus entered the kitchen, and he the bathroom so as to hold Frisk's hair out of her face as the hurled.

"How about I run you a bath instead, and get you some soup from Grillby's? How's that sound Pumpkin?", all Frisk could do was give him a thumbs up as the smell of tomato sauce came in from down stairs causing her to hurl once more. Sans teleported away as Frisk leaned against the cold wall, her head was pounding, her stomach was churning, and her whole body pulsed in pain... It began to overwhelm her as she layed down on the also cold floor... She could hear her heart in her head as well which also caused her great pain.

It felt like ages before Sans got back, he had just convinced Papyrus not to make more spaghetti and had placed the soup in the fridge for later, when he came up to the sight of her on the floor... She probably looked dead tibia honest, she skin was almost as white as her hair, her breathing had slowed, and her eye was closed from the pain. If it wasn't for her constant shivering Sans would of definitely thought so... He helpped her sit up, as she  grimaced at the slight movement. Frisk was very dizzy and couldn't focus on anything that was happening, as Sans started the bath, helpped her undress and get in it.

~···········~

After the bath Dr. Alphys showed up and after filling her in on what Sans had learned last night... Sorta... She determined what was wrong, "If the Human t-truely has magic but it's been d-dormant until now t-then it's most likely she's going t-through something similar to monster p-puberty...", both Sans and Papyrus looked at each other and then back at her with confused looks, "S-Seriously... *sigh*... Its w-when a monster's m-magic output c-changes... What y-you didn't t-think your m-magic got stronger because you g-got taller did you?  Anyway this could still be p-problematic... S-since she hasn't u-used her m-magic in such a long t-t-time, the magic b-b-build up is stressing h-h-her s-system too much...".

Sans took in what the Doctor was saying and came up with a conclusion, "So your saying since her magic hasn't been used in such a long time, there's like a blockage, and with the new magic output being added to it as well, it's putting so much stress on her body that it's resulting in her symptoms. Her fever, her hair turning white, her sleep walking and night terrors, as well as her blood turning black?". Alphys paused for a moment, "In a way y-yes although I can say t-that the sleep w-walking was most likely p-pre-existing, though I don't think it c-caused the blood thing either. I'd have to take a s-sample back to my lab to get a more i-inclusive result on that, but other then that y-yes. As for t-treating her I suggest l-letting her rest for a f-f-few days and start having her begin using her m-m-m-magic within a w-w-week, once it regulates she s-should get better within the m-matter of h-hours t-t-to one or two days."

The boys said their thanks to Alphys as she left to go back to her lab. Meanwhile Frisk began having fever filled sleep walking fits. They'd just find her in the weirdest places, in the kitchen pouring a never ending bowl of Temie Flakes, asleep in the bathtub, stomping up and down the stairs repeatedly, they'd even found her opening and closing the front door... Good thing Paps' installed a latch, both to keep unwanted people out and Frisk in... That is until Undyne stopped by for an unexpected visit... Thus breaking down the door...

Luckily it was mid day and Frisk was semi awake, as Sans helpped feed her soup... The shaking in her hands were getting worse... They knew they were running out of time... But if they were going to teach her how to use what they assumed was an accumulation of monster magic... They'd need to figure out which monsters or if it even was monster...
