Quantumtale After Life

Sans woke up again next  to Frisk only to find something was...wrong. Frisk looked well...hot. No, not in that way. She looked sweaty and was fidgeting. She was panting and looked uncomfortable. Sans frowned. He gently poked her. 

"frisk..? you ok there...?"He asked. Frisk opened her eyes and she sat up, hardly. She put a hand on her forehead. 

"I..i think i have a fev--" She stopped and covered her mouth. She immediately got out of bed and started running to the bathroom. Sans followed after her and waited at the door. He heard an all too familiar sound. Frisk was puking. 

"shit- frisk...damn it we have school today...hold on, ok?" Sans said as he teleported downstairs. 

"dad!" Gaster looked at Sans and smiled. 

"Morning, Sans. Where's Frisk??" Sans pointed up. 

"well she's a bit umm...sick.." Gaster looked at his son and frowned. He took the spoon he had next to the pan of eggs and hit Sans in the head with it. 

"I told you humans are fragile! You just wanted to ice skate soooo badly! Oh poor Frisk..." Suddenly a grotesque sound could be heard from Frisk's bathroom...Yup...she was still puking. All three skeletons downstairs winced. 

"FATHER! HOW WILL SHE ATTEND SCHOOL TODAY??" Gaster shook his head. 

"She won't be going Papyrus. Unlike us monsters this type of sickness worsen if not treated properly. They could even lead to death. So she is staying home today--" And Frisk was puking again. Gaster frowned. 

"I shall take care of her. I'll take the day off and assign Alphys to teach my class today." Sans looked at his father. 

"can't i stay home too..?" Gaster looked at his son with narrowed sockets. He raised his hands up in defense. 

"got'cha old man...let's go paps..." Papyrus nodded as they both headed towards the door looking up at Frisks room. Gaster teleported in front of her room and opened the door. 

"Frisk..? I'm coming in..." He said to let her know he wasn't intruding. She probably stopped puking since there was no more food left in her system. She was sitting on the bathroom floor with her back against the wall. She looked tired. 

"Oh you poor thing...can you stand for me...?" Frisk made some weird motion with her head. She tried to sit up but almost fell back down. Gaster helped her up. He set her on the bed and winced. 

"You will need a new fresh change of clothes..." She cleared her throat. 

"D-don't you have...to...go..?" Frisk asked, her voice was horse. Gaster shook his head. 

"Don't worry about me...now...let's see here...i have a few stuff prepared in case this happens...But first, clothes." He gave Frisk a new change of clothes and when she proved to be unable to change, he changed her without question. He looked away when needed. He laid her back on the bed wrapping her in blankets. 

"T-Too...hot.." Gaster looked at her with a soft look. 

"I know Frisk just...keep it on for me, ok?" Frisk nodded. Gaster put his hand on her forehead and his sockets went blank. Her temperature was really high. 

"You poor thing..." Frisk sniffled and coughed. Gaster went over to the kitchen and got some medicine. The first half of the day went quite well. He would stay by Frisk's side. Her fever didn't seem to break and she was coughing and sneezing. Gaster was a bit grossed out at all the liquids coming from her body, not to mention he had to get a change of clothes for himself as well as he found out Frisk has a weak stomach when sick. Frisk spent most of the time sleeping. She would be somewhat conscious and would make Gaster read for her. Not stories of course...she chose the novel Sherlock Holmes. At lunch however things got a bit more difficult. 

"Frisk, you need to eat something...please..." He said. Frisk shook her head. Gaster sighed. 

"Please Frisk...I promise you a bit of soup won't hurt you...i have toast too..?" Frisk looked at the man, still skeptical. He sighed. 

"Come on...please..." Frisk sat up and opened her mouth. Gaster breath in relief and started feeding her. It didn't take long for her to puke again. But at least SOME proteins got in. Gaster kept reading to her, giving her medications and just taking care of her. Suddenly the two boys came back when Frisk was asleep. Gaster teleported downstairs. 

"You wake her up and i will strangle you both with Papyrus scarf...Stop being so loud! I can hear you from miles away." Sans nodded. He looked up the stairs. 

"can i see her..?" Gaster looked at the room and winced. 

"I am...not sure..." He said. Sans looked sad. Gaster sighed and knelt down. 

"I'll let you know as soon as you can see her...even if it's tomorrow morning. Just for one day...leave her rest and recover." The two boys nodded. 

"IS SHE BETTER...? ANY BIT..?" Gaster gestured with his finger to his mouth. Papyrus covered his mouth. Gaster rubbed the back of his neck awkwardly. 

"Her fever sure as hell didn't break...and she's been having a hard time eating anything...and drinking too. It makes her react with gagging. It's quite the shit...it's called gastroenteritis...her muscles keep aching and she's been sleeping almost all day to make up for it." Sans frowned with blank sockets. He was looking down at the carpet. Gaster sighed and left to go back to Frisk. She was still sleeping. He thanked the Lord for that. He rubbed her head and sat down again. Fast forward a few hours later when Frisk woke up. 

"Ah...You are awake...I was about to make the boys some dinner. Don't worry, you will only eat some soup.." Frisk nodded. 

"W-water...p-please..." Gaster smiled and nodded. He teleported with her glass of water and she slowly drank it using a straw, since she still was quite sick. She felt disgusting...She was sweaty and hot and she needed to pee. She sat up and tried to get out of bed. 

"Woah there!" Gaster said putting a hand on her back and chest. 

"Where do you think you're going missy..?" Frisk cleared her throat. 

"Bath...room....pee..." He sighed. 

"Alright..." She went over to the bathroom and Gaster went downstairs. He made both of his sons sandwiches. Sans frowned. 

"aren't you going to eat...?" Gaster smiled. 

"Don't worry i already ate while Frisk was still sleeping." He quickly teleported back upstairs as he heard another grotesque sound. It was Frisk, puking again. Gaster sighed and looked at her worriedly. She was crying. 

"It hurts....i don't want to puke anymore....please..." Gaster picked her up and set her back on the bed. Tears welled up in his eye-sockets as he watched the poor little child. He sat on the bed with them and gave them a hug. 

"Shhh....just rest, ok?.." Frisk sniffled and wiped her eyes with her sleeve. She kept crying and mumbling stuff. Did it hurt so badly...? Of course it would, she has been puking any bit of matter going inside of her all day. She was desperate and the man was desperate to help.  

"I...don't...i...i shouldn't....he will get mad and--" Gaster stiffened a bit. Was she...seeing herself on the Surface...? She had a fever high didn't she...? Oh the poor thing.  

"Shhh....you're safe now..." Gaster said, his voice cracking a bit under the pressure. He never felt this helpless in his life. 

"...I'm sorry, daddy...i'm making this hard for you...he isn't here and i'm just...you're my dad now..." Gaster froze completely. She called him....dad...? She called him dad...she saw him as her dad....Oh his soul leaped inside his ribcage as he heard that. He always saw her as his daughter and this...This just filled him with joy. 

"Frisk...can you repeat that...?" In an attempt to make sure he was awake...But Frisk was already asleep in his arms.

"Sweet dreams baby...Oh how i wish i could have saved you from that place sooner...love you..." Gaster smiled and kissed her forehead. Frisk hummed in satisfaction and half awake mumbled. 

"...love you too..." Gaster sighed in satisfaction as he laid the small fragile girl in bed and sat down on the chair next to her. He put a hand on her forehead and to his relief the fever was starting to break. He hummed in content. 

"Thank God...." And he sat down on the chair next to her bed to fall asleep as well. He would wake up a lot through the night to help Frisk with her puking and her nightmares. In the morning however Frisk was nowhere to be seen and he had a blanket on him. There was a note: She went to Sans room. And there was a last bit that made him smile. 

You're the best Dad-ster ever!! Love you <3 

-Frisk, the little sick human 

He smiled at the note and pocketed it as he teleported to his room to get some sleep. Heh...Dad-ster...he liked that. He truly did. He fell asleep with a smile on his face as he finally stopped worrying, knowing she was feeling better and she was with his mostly capable son. But his soul was content. She saw him as her dad...That was more than enough and he promised to whatever God was up there: He will be a better father to her than the man who failed to give her love her whole life, and that? That was a promise he wanted to keep, no matter what.
