Chapter 6: Gaster

"That's terrible." said Toriel after hearing the news about what Asriel saw at the dojo

"I know. And it was like that when we got there." said Asriel explain the scene

"What was like what when who got there?" asked Frisk as she walked into the room, 8 years older (same age as Asriel), standing about 6.7 feet, wearing a purple and blue shirt, blue skirt, black leggings, a light jacket of gray, and somewhat longer brown hair.

"Someone or something attacked the dojo that Seth usually goes to." answered Asriel as he turned around to look at Frisk

"W-What?! Who would do such a thing?" asked Frisk in a panicked manner

"The police are looking into it right now." said Asriel as he turns to Frisk

"Still, who would do such a thing?" asked Frisk as she repeated her question

"Maybe I know, but, I am uncertain." said Toriel

"Who exactly? Can you at least describe him?" asked Frisk as she cupped her hands together in hope that Asriel has something

"He was tall. Taller than I am. Wore a black cloak or robe. His skin was pure white like a skeleton. Had two scars on his face, one near the jaw and another on the forehead." said Asriel as he described the figure to his mother and Frisk.

"Is that all?" asked Toriel as she began to think

"He also had a gaping hole on the palm of his hand." said Asriel as this shocked Toriel

"A gaping hole in his hand… that sounds painful." commented Frisk on the description

"He also said his name was "Gaster", do you guys know who that is?" asked Asriel about the figure named Gaster

"No. I have not heard of that name." said Frisk answering Asriel's question.

Toriel had a look of shock after hearing the name "Gaster" and then began to have flashbacks to when she was young and about to marry Asgore. She remembered the first time that She had met Gaster, for the first time, he was the royal scientist of the underground. Asgore had introduced her to him as part of the tour of the castle, the soon to be place where she would be living. The figure was a skeleton, a single father of two, a slim body, wore glasses, a lab coat, and He stood at about 7ft. Before long, Asriel then noticed that his mother had been in a blank transe and called out to her multiple times.

"Mom." said Asriel for the last time as he noticed his mother stare blankly at the table.

"Uh... oh! My apologies, my child. Were you saying something?" asked Toriel

"You were kind of staring into space for a while. Is everything alright?" asked Asriel concerned

"It was… it was nothing." said Toriel

"You sure?" asked Asriel

"Yes, my child. I am positive." said Toriel she then put a smile on her face.

"Ok. Just making sure." said Asriel as he got up from the table and went to his room.

Frisk turned and looked at her mother. She tilted her head knowing something was wrong, then, she turned and looked at Seth, He was just watching TV. Frisk turned back around and gave her mother another look before walking away and started watching what Seth was watching.

Asriel locked his bedroom door and called the only other person who may know who this "Gaster" is.

Elsewhere, a phone starts ringing in a familiar household...

"Hello?" answered Papyrus as he answered the phone

"Hey, Pap. It's me, Asriel." greeted Asriel

"Ah Mini Asgore. What do I owe this call?" asked Papyrus

"Well… I have a question…" says Asriel as he lays in his bed

"Ok." replied Papyrus

"Who is "Gaster"?" asked Asriel

"Hm… I do not know. That name does not sound familiar…" answers Papyrus

"Oh… well- can I ask Sans then?" asks Asriel

"Sure thing." says Papyrus as he takes a deep breath and yells...

"SANS! GET OUT HERE YOU LAZY BAG OF BONES!"

"You wanted me?" said Sans as he appeared right behind Papyrus

"AH! Oh- There you are. Mini Asgore would like to talk to you."

"Mini Asgore? Oh Asriel. Ok, give me the phone." says Sans as Papyrus hands him the phone. He then answers...

"Hello?"

"Hey, Sans. It's Asriel."

"You wanted to ask me something?" asked Sans

"Yeah. So… do you know who "Gaster" is?" asked Asriel as then Sans' eyes went dark after hearing the name. He then asked…

"Where did you hear that name?" asked Sans

"That's what someone addressed themselves as when I went to take Seth to karate practice. Although the place was practically ransacked when we go there." said Asriel explaining the scene

"...yes" says Sans quietly

"Huh?" replies Asriel

"I know who "Gaster" is." said Sans

"Great! Now who is he?" asked Asriel as he continued to find answers

"Let's speak about this in private. I feel uncomfortable talking about it in front of Papyrus." said Sans as He turned to look at Papyrus cooking.

"Um… ok. Where do you want to meet?" asked Asriel as he scratched his head wondering why Sans wants to meet in a certain location.

"Grillbz. Be there." said Sans as he hung up the phone

"Um… ok. Should have asked him what time?" said Asriel as he looked at the phone with confusion

Later at grillbz…

Asriel walks into the pub, looks around for Sans and sees him in one of the booths. He walks over to the booth and sits across from him.

"So. You want to know who "Gaster" is, huh." said Sans with his eyes closed

"Yes." said Asriel as he nods his head

"Why exactly?" asked Sans as he opened one eye and looked at Asriel

"Why... Why was he at the dojo? What was he looking for? WHO was he looking for? Did he find them? Why did he destroy the dojo? I. Want. Answers. DAMN IT!" said Asriel as he reached off the table with fire burning in his eyes.

Sans just looked and said…

"You're worried that he is after Seth, Aren't you?" said Sans as he practically read Asriel like a book.

Asriel, then realizing that Sans figured out why he wants to know who Gaster is. He backed off and sat back in the chair.

"I figured as much. Alright, I'll tell ya." said Sans as he closed his eyes and took a deep breath.

"Gaster… was the royal scientist of the underground prior to Alphys. He was a well respected scientist among the people on the underground. His actual name was Dr. W.D. Gaster, He-"

"Sorry for the interruption, but, what does W.D. mean?" asked Asriel as he interrupted Sans. He then answers with...

"...Wing ding…"

"Wing ding?" said Asriel raising an eyebrow

"Yes. His full name was Dr. Wing Ding Gaster."

"That sounds rather…" said Asriel as he then looked at Sans where he noticed that he eye was glowing blue.

"Sounds rather what?" said Sans with a glowing blue eye

"N-nevermind." said Asriel as he then looked away and back at Sans again and his eye went back to normal.

"Anyway, He was also the mentor of Alphys as well." continued Sans, anwsering Asriel's questions about Gaster

"Really? That's interesting." said Asriel as he rubbed his chin.

"Moving on, he was… was…" said Sans before he went quiet.

"He was what?" asked Asriel as he tilted his head.

"My father." said Sans as he looked down at the table and Asriel jumped back in shock after hearing.

"Your father?!" said Asriel as he looked at Sans with shock as to what he had just heard.

"He had been a royal scientist for as long as your father had been king. I was just a tike when your parents got married. And Papyrus… well… he was just born." said Sans as he looked back up at Asriel.

"I… see." said Asriel as he continued to rub his chin.

"Well from what I remember, He said that He met Her when your dad was giving your mom the tour of the castle... So that She would not get lost in it when she lived there." said Sans as Asriel squinted his eyes at him

"Well. I now know who he is. But, why was he at the dojo?" said Asriel as he repeated one of his questions

"Look, Asriel. I am just as lost as you are when it comes to his motives. But, one thing I'm probably certain about, is the fact that Seth may have something to do with it" said Sans

"That's one thing that I hope is not true." said Asriel as he looks away from Sans

"And That's the only thing we can do… hope. Hope that Seth is not the reason." said Sans as Asriel got up from the table.

"Thank you, Sans." said Asriel as he walked away from the table and left the pub.

As Asriel left, Sans began to think. Why is he here and How is he here? But, one thing always came up when thinking about those two questions… Seth maybe the problem. He knew something was off about Seth when he first laid eyes upon him. Other than the monkey tail that proceeded from his backside, but, where he came from? As Sans was still thinking about his questions, Grillby walked up to him and told him that it was time to leave, it was closing time. Sans got up from the booth and left the pub with these questions in mind.

Back at home, Asriel walks in to see Frisk sitting in a chair with her arms folded...

"To be honest, I was expecting to see Chara come home before you. Where have you been?" asked Frisk with a stern tone in her voice

"Looking." replied Asriel

"For what?" asked Frisk continuing her questioning

"Answers." replied Asriel again

"Answers. About wh-... this is about that "Gaster" figure, isn't it." said Frisk as she looked at Asriel.

"Yes." answered Asriel as he nods

"Alright. Who did you ask?" asked Frisk as she stood up from her chair.

"Sans." said Asriel as he turned away

"And why Sans?" asked Frisk with an eyebrow raised

"Because I had already asked Papyrus early and he hadn't even heard of the name 'Gaster'." said Asriel as he turned back around to Frisk

"And then you asked Sans." replied Frisk

"Yeah and he knew." said Asriel as he then sat down

"How much?" asked Frisk as she continued to bombard Asriel with questions.

"He knew that he was the royal scientist before Alphys." answered Asriel

"Really. What else?" asked Frisk with shock

"He also told me that… well…" said Asriel as he began to rub the back of his neck

"Well what?" pursued Frisk

"That Gaster is his father." anwsered Asriel

"C-come again?!" said Frisk as she became even more shocked by this fact.

"Yeeeeaaah." said Asriel as he rubbed the back of the head

"I… I'm at a loss for words. You mean to tell me that the thing that ransacked Seth's dojo is Sans' dad?!" said Frisk

"That's a basic roundabout. Yes." said Asriel as he looked around the room.

"I… I need to register this fact." Said Frisk as she puts her hand to her forehead.

"Well. Now what are we going to do?" asked Asriel

"I don't know. We can't do anything right now. We'll have to think of something later. Right now it's late for that. We have school in the morning." said Frisk as she left for her room.

"Guess I'll… sleep up a plan." said Asriel as he walked to his bedroom and went to sleep.

The next day at school, Asriel is sitting alone, thinking of why Gaster would attack the dojo? He keeps on thinking about why until…

"Hey Azzy" said a female voice happily as she greeted Asriel who was sitting alone for the time being.

"Hmm. Oh hi, Stella." said Asriel as he greeted the voice when has now been revealed to be named Stella

Stella is the same type of monster that Asriel and the rest of his biological family is. Same age as Asriel, but younger by a few months. She sported a red shirt and a thin white jacket, She also wore brown shorts with black stockings underneath. Horns developed at about 3 and a half inches, she stood up to eye level with Asriel in terms height and she had some hair that hung over her eyes as well. Stella then sat right next to Asriel, hugged his arm and then asked him…

"So… how was your weekend?" Stella asked she squeezed Asriel's arm

"Could have been better…" answered Asriel

"What happened?" asked Stella as she leaned closer to him

"Someone ransacked the dojo that Seth goes to." said Asriel as he then pulled his arm from Stella's grip and wrapped his arm around her.

"That's terrible." said Stella as she looked at Asriel

"What's worse is that I think someone is after Seth." said Asriel as he stared into Stella's eyes

"What makes you say that and who is this person?" asked Stella as she sat up-right and looked at Asriel

"Well… You know how Seth is not... normal?" asked Asriel

"Yeah. I mean he has a freaking monkey tail." replied Stella

"Well… I think they are after him for that." said Asriel as he looked at the tile floor.

"Still who is the person after Seth?" asked Stella with concern

"I don't know… a person who wants to exploit Seth for his abilities… I guess..." said Asriel as he became more concerned

"Bad people…" continued Stella as she then looked at the tile as well

"Yes. People like that." said Asriel as he looked up at the wall.

Stella looked up and turned her head towards Asriel. She then grabbed Asriel's hand and said…

"Don't worry, Asriel. You know that Seth is adopted to the royal family. YOUR family. If anything were to happen to him, I'm pretty certain that your dad would have the entire royal army on that person's ass." said Stella trying to reassure Asriel

"I guess you're right." said Asriel as he turned and looked at Stella

The school bell had just rung. The two got up and were headed towards their respected classes, but, before Asriel could leave, Stella grabbed Asriel's shoulder and twisted him around so that he was facing her direction and kissed him.

"Love you. And try not to worry about your brother so much." said Stella after she had kissed Asriel as she left for class. Asriel just stood there flustered after what had just happened.
