Chapter 9: Explanation

Gaster sighed as he made himself a tea and looked at the four children, waiting for him to explain, not able to abid it. Even Papyrus and Sans remained there.

"Well... " He started. "Sans always was... Special, one could say. He was born too soon, way... Too soon. It was clear to the doctors that he only had a few weeks before he'd die. His stats all were on one... Weirdly. I... I didn't know what to do. I wanted a child so long just to realize that it could die... Day and night I searched for something to help him. To help my son live, but I never... Never found anything." Gaster made a small pause, looking at Sans. The comedian of course grinned, even if he was upset. He walked out of the kitchen and upstairs. He didn't want to quiet hear all that.

"Then..." Continued Gaster. "One night I remembered... That I had something in my lab. To that day 5 humans had fallen into the underground already and we had gathered 4 SOULs... I... I distracted their DETERMINATION before... So I had liquid DETERMINATION in my lab... Something very dangerous but also powerful... It was amazing how much DETERMINATION the SOULs held, without it having any effect on them... I know that there is a SOUL that has even more DETERMINATION than others but that doesn't matter... I took some of that... And injected it... I-Into Sans' SOUL... With hopes... It'd help..."

Alphys lifted her hand into the air. "B-But isn't that simply like letting a m-monster absorb a human SOUL...? Isn't i-it dangerous...?" She asked in worry. Gaster shook his skull. "No no... The SOUL itself is... Different from the actual DETERMINATION... For example could Sans never pass the barrier. For that you need a human and a monster SOUL." He told. Alphys nodded for him to continue.

"So... So it worked and our son lived... I repeated it rather often, without his stats raising... But at least he lived! And... When he was... About 3 he started using his magic. That normally doesn't happen. Because... Children are able to use magic with about 5 but only small things... When... When Sans already... Teleported to other places... His SOUL started changing too... More to the one we know now... At the start it was glowing yellow... That was his trait. The one he created for himself... Because he never got any DETERMINATION from a yellow SOUL. I am sure with that..."

Undyne now raised her hand. "So that means... Sans is part human or what?" She asked, confused. Again, Gaster shook his skull. "No... He only managed to show which trait he has. Through his SOUL I mean...". Undyne leaned back. "Ah..." Even though she still didn't quiet get it.

"Later on it took the colour of his magic, which is blue... Time to time I gave him less DETERMINATION and these days now he isn't taking much at all. Only sometimes... Weirdly, it gives him a gigantic boost, which can go critical if it is too much or without anyone watching him. It is better if he doesn't use it often..." Gaster looked down as he finished telling them most of it. Of course he kept some things for himself.

Alphys tried to get it all into her head. "S-Sans must be very special t-then... You must b-be proud!" She said with a smile, pushing her glasses up. Gaster sighed lightly. "Many people in the lab say I only did that for my projects but that is a lie... If I wanted to do it for projects... I... I could never even think about that!"

Undyne snickered softly. "Well, I think that is heroic." She mumbled audible. Gaster raised a non existent brow. "Heroic? Why?" He questioned, taking a sip of his tea. Undyne shrugged. "Because... You took all that work on you, just for your son. You could've let him die simply, but you haven't. You cared for him... And you are a nerd that cares for his son. That's awesome!"

Papyrus let out a giggle. "YAY! DAD IS A SUPER HERO!" He shouted. Undyne thought about something. "So, Papyrus was born normally? Or was it like with Sans?" She asked, full of curiosity still.

Gaster put his mug besides for a second. "Papyrus was born normally." He told them, smiling lightly. Undyne then had another question. "Alright... And what about their mom? Has it something to do with her? That Sans is like that I mean."

Gaster scratched his arm, looking down. Papyrus noticed and answered instead. "SHE TRAVELED AWAY TO HAVE A BETTER CAREER! BECAUSE SHE IS A DANCER!" He exclaimed with a few giggles. Gaster tilted his skull and chuckled. "You heard it." He murmured and took a sip of the tea again.

Alphys tilted her head lightly. "Will we stay over n-night?" She asked, looking at the tallest of the skeletons, who nodded with a grin. "Of course. It is too late to send you home now."

Undyne raised a fist into the air. "BY ASGORE, THIS NIGHT IS GOING TO BE THE BEST NIGHT THERE EVER WAS!" She shouted, grabbed Papyrus and threw him up. Of course she caught him again. Papyrus let out a cry of joy. "YAAAAAAY!"

Gaster rolled his pupils. "You all still have school tomorrow." He said, stretching lightly. The two monsters 'awed' at the same time, but still giggled.

Meanwhile, Alphys thought about the possibilities of pillow fights, books, animes and games they could play together the whole night. As if they would sleep! To be honest, the future scientist never was on a slumber party but she had seen it on TV and that was enough knowledge.

Gaster chuckled softly, a hand at his frontal. "I will start making dinner, alright? You go up and play." He suggested with another smile. Papyrus giggled and pulled Undyne with out of the kitchen, into the direction of his room. Alphys noticed and followed them fast with a small yelp.

Sans dropped his phone onto his bed where he sat, when the door slammed open. Undyne rushed in. She was the one, that pulled Papyrus with herself inside now. The smallest skeleton giggled still and still much.

Sans raised a non existent brow at the three. "You could've knocked, y'know...?" He mumbled, rolling his pupils. But it wasn't meant in a rude way actually. Papyrus tackle hugged Sans. "UNDYNE AND ALPHYS SLEEP HERE TODAY!" He exclaimed.

Sans chuckled softly. "Sounds awesome." He said to his younger brother, hugging back while trying to shove his phone away a little. "Lemme guess you will stay up all night?" He asked, snickering.

Papyrus nodded fast, tugging his scarf into the right direction. "OF COURSE! And when dad comes in we are going to be totally quiet but we actually play..." The skeleton whispered the last part, so their father couldn't hear.

Sans poked Papyrus' frontal. "Aha. I'll fall asleep anyways. I always do and y'know it." He laughed lightly. He spotted Alphys, who showed some interest in his books. The comedian put Papyrus asides and came over to her. "What'cha looking at?" He asked.

Alphys shrugged. "What language is that? I-I've never seen it..." She questioned, holding a notebook up. On the cover were weird symbols. A tear, a hand holding up two fingers, a skull with two crossed bones and another tear.

"It's not English for sure.." Muttered Sans, taking the notebook. "The symbols write out Sans by the way. It's a... Journal of mine y'could say." He told, going through the pages. They were only written with those weird symbols.

Alphys was slightly confused, but decided not to ask. "You h-have a lot of books about science and so o-on too... Do you want to b-be a scientist like your f-father...?" She asked.

Sans shrugged. "I have thought 'bout it... Seems like a lot of work actually. That is why... I don't really know. I'd really like to work somewhere... With a higher position y'know? So I can change things..." Sans grinned wider.

Alphys let out a snort. "Sounds cool. I h-hope I can be a scientist later w-when I grow up." She told. Sans nodded at that. "Bet ya will also be one. Y'seem pretty smart actually. And you look sciency too."

Undyne leaned between the two, one elbow on each shoulder. "What are ya nerds talking about?" She asked, curious. Alphys scratched her arm lightly. "Only a-about... About...", "Future." Answered Sans instead. "Alphys wants to be a scientist."

Undyne grinned widely at her female friend. "Well, of course she is going to be one! The best of them all!" She shouted, not too loud.

Alphys giggled lightly, but shrugged. "I don't know... I'll j-just hope, hm?" She mumbled audible, with a small smile.

Suddenly someone wrapped their arms around the three, or at least tried to. "HEY!" Shouted Papyrus' voice. "IF YOU HUG I WANT TOO!" He giggled.

Gaster put the dry noodles into a pot filled with boiling water. He let out a sigh, making circle motions with the spoon in the pasta sauce. So many things were on the scientists mind. He looked at all the children drawings at the fridge.

The skeleton silently chuckled to himself. He opened the fridge and his smile vanished. Because always when he saw those red vials, all the way up in the fridge, he felt bad. Because he knew, it would have been better to... Let him die than giving him those problems.

Gaster shook his skull. "Paranoid. I am just paranoid..." He said to himself. Then added:"And crazy..." He rolled his pupils and moved his fingers along the crack that went upwards his right eye socket. Then the one that went down from his left one.

Those cracks always remembered him of two special days. But also of one unfortunate one. Another sigh escaped Gaster. He took some basil, closed the fridge and put some of it into the sauce.

He watched as the noodles slowly sank into the water, loosing their straight form. As soon as they were ready, he smiled and shouted something up the stairs. "Dinner is ready!"

It didn't take long until Papyrus trashed out of the door, pulling Sans with. "GOGOGOGOGOGOGOGO!" He shouted with a grin. Sans chuckled. "Bro! At that pace I'll fall downstairs!" He said.

Undyne rushed by. "I'll catch you, punk! Don't worry!" She shouted at the two, running down in front of them. Alphys nervously looked after them with a frown. "Y-You will get hurt!" She cried out, so they'd slow down, without succeed.

Arrived at the end of the stairs, Undyne opened her arms. "Go, Sans! Fall! I am waiting for you!" She meant with laughter. Sans groaned as he got pulled further next to her. "I am not going to fall on porpoise, 'Dyne!"

Papyrus giggled a lot, sitting with his brother on one side of the table, while Undyne settled down on the other, joined by Alphys. Papyrus' eye sockets widened at the sight. "SPAGHETTI!" He shouted with joy. He loved that.

Sans chuckled. "At least we know now he is not an impasta." He whispered to the others. Alphys just puffed her cheeks. She didn't... Really know if she liked all those puns. Undyne, though, tried to hold in some laughter. Gaster himself just chuckled. "You sure got your mothers humor. Or shall I say... You are very humerus?"

Papyrus hid his face in his scarf to stiffen his light scream. He heard too many puns every day it was too much for him. Even if he had to smile every now and then.

Gaster put noodles on five plates, all covered in the pasta sauce. Then he put the plates in front of the for children, along with one at the end of the table for himself. He sat down and watched how the children all started to eat.
