Chapter 10

Backstories aren't as

sweet as they say

And were back to the normal Frisk's pov today :)

Jasper and Gaster's quiet voices floated in the living room before I felt their souls disappear from our plane of existence.

I sighed and leaned further into Sans tense embrace before looking up at my husband.

"With Jasper's magic coming in it makes me nervous that we can't even help him with it. Your father says it's to dangerous for us to be by him yet while he practices." I say rubbing my arm.

"Gaster knows what he's talking about when it comes to void magic. We have to trust him, unfortunately." Sans says pressing a chaste kiss to my temple.

"Sans, why didn't you ever tell me about your father? I know it must have been difficult but…. How come you never brought him up?" I say feeling Sans tense up.

"Oh yeah, tell us why you let your own son disappear on us." Flowey spat from his small window ledge.

"Weed, be quite." Sans snarls before rubbing his eye sockets and looking down at me.

"Gaster was the original royal scientist before Alphys took over. He supplied the containers for the human souls for the king, created the core in the early days of the underground, and was the head of magical studies. His main focus was to try and scientifically explain how magic worked." Sans says. His voice was monotone as if he was trying to distance himself from his words.

"His experiments weren't always, approved, by the scientific community. One of his favorite things to test was expanding monster magic with human determination taken from the souls we had already harnessed. I was the first to volunteer." Sans sucked in a breath before continuing.

"It worked to an extent, but it nearly killed me in the process. You've seen first hand what human determination can do to monsters." Sans says looking at me while Flowey snarled.

I shuddered at the thought of the amalgamates, and with the thought that Sans could have become one of them.

"After learning he could further magic, he decided to test it more rigorously on himself. He spent months, no years, studying the effects of human determination on his own void magic. During this time was when my mother passed away. I think that's what finally drove him into the madness." Sans says.

The room felt colder as Sans swallows thickly and blinks a few times before looking away from me and staring at the walls.

"Gaster was trying to see if his void magic could collapse in itself and form a black hole of sorts. His experiments pushed his own magical capacities past monster understandings. The entire point was to see if he could travel through time with the worm hole and gather more human souls through various timelines. He failed." Sans says staring holes in the wall.

"I think at the end he was really trying to see if he could get my mother back. She had fought through the war side by side with him and given birth to both Paps and me with no issues. In the end she had fallen down because she lost all of her HP, her hope, for our future. She was convinced we were going to be trapped down here forever and she couldn't live knowing we'd never see the sun." Sans says slumping back.

"If only she knew now that I see the sun every day, and that we made it out." Sans says blinking back a few tears.

I lean closer to him and squeeze his hand.

"You don't have to say anymore Sans." I say softly.

"No, you need to hear this." Sans says his voice cracking.

"Gaster had been in his lab for weeks when I felt an enormous magical surge inside the house. I went in to investigate and saw him right before he was swallowed by his own creation. His face was so terrified as he screamed that he loved us while him and his assistants were consumed." Sans says.

Sans coughed and rubbed his face as the deathly silence in the room was interrupted by Flowey's snicker.

"Your dad was dumb enough to get killed by his own project? Pathetic. Sounds just like you." Flowey says cackling.

Sans eyes narrowed as he used his magic to bring the small plant close.

"My father did more than you could ever dream of accomplishing worm. If you dare insult him in front of me I will slice you apart and feed you your own entrails." Sans hisses making Flowey's face drop.

"Sans please." I say putting my hand on his arm.

"Tch." Sans throws Flowey away and sighs.

"The next day after the incident I found out nobody remembered him other then me. Paps remembered our mother but not Gaster or any of his co workers that had been taken with him. I spent months trying to piece together his blueprints and notes. After a while I just gave up and assumed he was gone forever." Sans says finishing his story.

"Gaster did all of that but nobody remembers him?" I say slightly amazed.

"From what I gathered his physical body was destroyed while his conscious somehow lived on inside his own void. Effectively erasing him from the memories of every living monster." Sans says finally relaxing.

"Then why could you remember him?" I say curious.

"I've theorized and thought about it for years and the only thing that makes sense is all the determination I have." Sans says with a shrug.

"How come he's back now? If he was gone, how did he manage to return to our world?" I say rubbing my chin.

"You're guess is as good as mine. But he's here now and Jasper seems to have taken a liking to him. I am glad he's back but I don't know for how long." Sans says.

"So we're stuck with him for now? But that should be good. You can catch up on all sorts of things!" I say smiling.

"If things go well." Sans says as Jasper and Gaster's souls reappear in Jasper's room.

Flowey catapults out of the living room into Jasper's making Jasper giggle.

"Hi Flowey! Did ya miss me?" Jasper says laughing.

Jasper floats into the living room with a glitchy Gaster walking behind him.

Gaster had his hands behind his back and had a faint smile on his skull.

"Hey baby, how'd the lesson go?" I say cuddling Jasper as he zooms into my arms.

"It was awesome! Grandpa Gaster showed me how to control the void better! I even got it to form a circle this time!" Jasper says excitedly.

"That's great kiddo." Sans says rubbing Jasper's messy curls.

Jasper grins before looking over at Gaster.

"Grandpa you can sit down. Mommy doesn't mind." He says happily.

"(No I should not linger in this realm longer than needed. Sans, Frisk.)" Gaster says nodding in our direction.

"Gaster wait, before you leave, I have something for you." I say getting up with Jasper in my left arm.

I hustle in our room and grab the small box before hurrying back.

"What is that mommy?" Jasper says trying to touch the gift.

"You'll see." I say chuckling.

"Here. Toriel made it for you." I say handing the box to Gaster.

"(Oh why thank you Frisk.)" Gaster says smiling warmly.

He opened the box and gasped before pulling out the bright orange sweater from inside.

"We figured it was cold sometimes where you stayed so Toriel made this for you. We hope you like it." I say smiling as Jasper talked with Flowey.

"(Thank you Frisk, it's lovely.)" Gaster says pulling the warmly made sweater over his head.

With the large sweater on he looked less intimidating and more dopey.

Jasper giggled and pointed.

"You look like Velma from Scooby Doo!" Jasper says laughing.

Gaster chuckles and smiles before pushing his glasses up and folding his hands in front of him.

"(Thank you for your kindness, but I must depart. I will see you later Jasper.)" Gaster says waving before disappearing.

Jasper giggles and whispers something in Flowey's ear making the small flower giggle before he unwound his tendrils from my arm and entered Jasper's room.

"Are you hungry Jasper?" I say patting my sons unruly curls.

"A little. Can I have chicken nuggets?" Jasper says hopefully.

"Not a chance bucko, you had that yesterday. Mom made some spinach and artichoke dip." Sans says scooping Jasper out of my arms.

Jasper pouted slightly but allowed Sans to carry him in the kitchen and dig out the healthier alternative.

Sorry for the shorter chapter today but I couldn't get the time skip for the next chapter just right unless I split it up. I sorry :(

But don't you all think of Gaster as a big dopey scientist? I get a doc brown vibe from him. That his mind moves to fast for the rest of him to keep up. And I just wanted to show him in an oversized sweater XD

But next chapter we're going to get a slightly older Jasper when his magic really shows up. He'll get his "special attack".

Toodles :3
