Meredith and Pelagius, Undyne's parents as they introduced, sat at the table as Undyne sat next to Jellian who tapped a few keys of the Piano. They had been here for an hour now, and Jellian said this was a 4 hour lesson, so they weren't leaving for some time. Sans seemed uncomfortable around the two parents who were rather quiet. He was holding onto Papyrus, the baby in his lap. His own parents were quiet too, so it unnerved him to no end. The two had scolded Undyne for her loudness, even if it was a light scold. Meredith turned to see him looking at them nervously, making her curious. Sans looked away quickly, holding his brother tighter. She coughed into her hand to get everyone's attention.
"I just remembered Pelagius and I have errands to run, we should be back when the lessons are over, would this be okay Jellian?" She asked.
"Oh, sure thing! if you do end up getting stuck or late, just give me a call, okay?" Jellian replied with a smile. Pelagius was confused as he was pulled along by Meredith out the door. Sans began to calm down considerably after that. Undyne thought it was weird, but shrugged before she began to play notes on the piano. It was a pretty song, even when Undyne hit the wrong keys time to time. Jellian got up, hearing Papyrus whine and whimper now, taking him from Sans.
"Does anyone else want anything? Milk? Water? Tea?" She asked, bouncing Papyrus in her arms.
"Milk please" Sans mumbled softly.
"Water please!" Undyne and Alphys both said at the same time, before looking at each other, then started to giggle. They were left in the main room together, Jellian going into her kitchen.
"Soooo" Undyne began, kicking her feet, facing the two now.
"Where did you all come from?"
"O-Oh, my parents live between Hotland and the Capital" Alphys told her.
"We live in Snowdin" Sans told her, seeing a sharp, toothy grin from Undyne.
"Cool! we live here, mum and pop thought it'd help me calm down if I took piano lessons with Miss Jellian" he told them. Sans nodded, a little uneasy at the mention of the two.
"They're very quiet" he mumbled out, Undyne nodding.
"Yup! Mum and Pop can be super quiet and calm!" she sounded enthusiastic about it.
"But Mum and Pop are really cool too! they just don't like me attacking the mail man" Sans stared at her, as did Alphys.
"...Why...Why would you...?"
"I wanna be in the Royal Guard, just like Gerson!" she told them.
"But Mum said she didn't want me doin' any real dangerous stuff till I was older" she said with a pout.
"But her and pop are gonna sign me up for some sports!" Undyne seemed excited at the prospect, and Sans looked to calm down at this. Jellian came back, bottle feeding Papyrus, before she gave him to Sans. Papyrus cooed happily behind the bottle, looking at his brother.
"Sorry, I'll get the drinks now" Jellian said, Sans was smiling at his brother.
"Hi Pap" he greeted, holding one of his brother's hands. Undyne tilted over, looking at the baby.
"He's cute! What's his name?"
"Papyrus, daddy let me help name him" Sans told her, leaning against the pillow now. Undyne crossed her arms, watching them.
"If mum and pop didn't have a lot of trouble just to have me, I'd have lots of brothers and sisters" Undyne sounded a little jealous of Sans, who looked at her, squirming a little.
"S-Sorry" Sans apologized, it seemed her parents really did care about her if she was the only child they could have.
"Yeah, kinda sucks, but the other littler kids where we live like me!" she was beaming again, nothing could really get this girl down as it appeared.
Asgore's reaction was just as Gaster expected. Body tense and stiff, eyes showing fury. He kept quiet after that bomb drop.
"That's... not the greatest news now is it?" Asgore managed to say calmly as he could, almost forcing it out.
{I wasn't happy to hear it myself, I just... I need paperwork, something to make the adoption official, you may have given your word but...} Gaster started to him.
"Of course... I'll get onto that" He told Gaster, hands trembling a little.
{Sir, you're taking this much harder than I was expecting} Gaster was worried for Asgore who gave a deep sigh.
"They're children Gaster, small children... Who were abandoned by the very ones who should have been giving them a loving home and make them feel safe, not fear if they were going to be unjustly punished for something they weren't even aware of" Asgore said, voice breaking before he took a deep breath.
"If Toriel were in my place, I'm sure she would be more furious than me" his voice was soft and sad, looking at the ground, still feeling guilt for what caused their divorce.
{I won't deny that, and I'm sorry I brought it up, but... I don't want them trying to get them back, Sans would have a complete magic outbreak that could hurt not just others, but himself} Gaster explained.
"Don't be sorry Gaster, I'm glad you brought it to my attention, I'll be sure to get the papers for you soon as I can" Asgore said, smiling at him now. Gaster smiled back, nodding to him.
{Thank you your Majesty}
Papyrus squealed and squawked as he watched Undyne play on the Piano with Jellian. Sans could barely hold onto him, 2 hours had passed now, the song began to end. Jellian grinned at her.
"Great! How about you and the others take a 45 minute recess?" she asked them.
"Alright! Come on!" Undyne was quick to drag Sans and Alphys with her to the backyard. There was a swing set, sandbox, and small slide. Why Jellian had this was beyond them all.
"Is it really okay?" Alphys asked, nervous of using the equipment.
"She let's me do it all the time!" Undyne told them, leading them out to the playground.
"Oh! Alphys! Lemme push you on the swing!" she was pulling Alphys along with her to the swing set, Sans went over and sat in the sandbox with Papyrus. Papyrus was patting the contents of the box, giggling loudly. Sans smiled at his brother, making a pile of sand. Papyrus smacked it, making it fall, making him clap his boney hands together with a laugh. It was short lived however, Papyrus had stopped clapping and laughing, looking around now.
"What's wrong Pap?" Sans seemed curious to what made his brother quiet down. Papyrus seemed to be staring in one place.
"Bahh!" he squealed out, waving an arm in the direction he was looking. Sans looked over, seeing he was looking at Jellian through the window.
"What about her Paps?"
"Nyhah-Buh!" he gurgled out to him, flailing his arms now, Sans blinked.
"N-No... She's not that" he told Papyrus, seeming to understand the baby babbling. Papyrus had habit of "saying" that whenever he saw Gaster.
"Nyhah-Buh!" Sans blushed brightly at his brother saying it even louder. He saw Undyne and Alphys looking over at them. Pulling his hoodie over his head, Sans hid his face.
"Paps, stoooooop!" He whined down, making his brother giggle. the Swinging stopped, Undyne and Alphys switching between looking at the boys, then at each other.
"Do you know what's going on?" Undyne asked Alphys.
"I-I think Papyrus is doing the noise to Miss Jellian what he does to Mr. Gaster"
"Whossa Gaster?" Undyne asked, eyebrows furrowing now.
"Sans and Papyrus' Daddy"
"Oh... So like... does that mean he's seeing her as his mum?"
"I guess so" Alphys seemed a little unsure, but it made some sense to her.
"She'd love that!"
"She is really nice, and Sans likes her lots too" Alphys commented as Sans whined even louder, able to hear them talking.
"I do noooooooooot!" Sans complained, Undyne laughing even harder. She went over to him, arm over his shoulder.
"Look Sans, if you wanna see her super duper happy, you should call her mum!" Undyne explained, making Sans cover his now blue colored face with the hood.
"But, but I don't wanna"
"Really now?" Undyne was staring at him intently. Sans looked at her, before burying himself in his hoodie.
"I...I kinda do... but I dun wanna make her mad"
"It'll be fine!" Undyne told him, pushing him to the door inside the house despite him digging his shoes into the ground. She began to knock on the door loudly, to get Jellian's attention. Sans glared at her as the door opened up.
"Something the matter?" Jellian asked, peeking her head out the door, curious. Sans shuffled his feet shyly as Undyne spoke up.
"Sans and Papyrus see you as their mum!" Undyne stated it with so much confidence and bluntness, Sans almost screamed. Instead he let out a choked wheeze and squeal hybrid of sorts. Papyrus kicked and squirmed, arms out to the adult now, smiling widely.
"Nyhah-Buh!" Jellian had her hands over her mouth, eyes widened now. She was smiling behind her mouth, face flushed. Sans looked down, face almost the color of the water as she knelt down to their level. She took Papyrus who let out peals of giggles and laughter, grabbing onto her "hair" and nuzzling her. Sans rubbed his arm shyly, unable to look at her.
"Sans" Jellian began to him. Crossing his arms, he whipped his head in the other direction. He realized he was not going to be able to just walk this off, but he was so nervous about just admitting it.
"Did someone get a case of the shaking bones?" she asked him. Sans stopped, trying hard to not laugh.
"Oh come on, I can see right through you that you want to laugh" Jellian said, Undyne and Papyrus were just... staring at her. Sans let out a small giggle, cracking.
"Guess I just needed to tickle your funny bone" she said, before he busted into louder giggles.
"Please no" Undyne whined, covering her face. Sans seemed a little more opened now, going over and hugging her.
"I guess this makes you two..." she began, hugging him and Papyrus now.
"Jellytons" she said, Undyne threw her arms up with a cry, before falling onto her back.
"THAT WAS SO LAME"
