The Final Timeline (Undertale Sans x Frisk)

Chapter 45 Growing

He just disappeared back to the house and threw himself on the bed, screaming into his pillow. Thoughts were racing through his mind. How could he get you pregnant?! You were so much more fragile than any other humans he had met, only 20hp because you refused to fight. What did this mean for the timeline? Will the baby have reset abilities too? Would you be able to handle giving birth with such low HP? Would the kid have powers like him?

He screamed again, and Papyrus knocked on the room door.

"BROTHER?! ARE YOU OKAY IN THERE?" Papyrus asked. "DO YOU NEED ANYTHING? WHAT HAPPENED?"

Papyrus... poor sweet Papyrus.... How was Sans going to tell him he was an uncle? That you were having a baby? And how did the soul form so fast?! It should take at least two months for a human soul to form. Did this have anything to do with monster magic?

"i-i'm fine paps!!" Sans answered. "just trying to sleep."

"AT 4 IN THE AFTERNOON?!" Papyrus bellowed. "IN DON'T THINK SO!"

Suddenly the door flew open, Papyrus' foot in place where the door would be in the doorframe. Sans jumped when the giant bang of the now unhinged door fell to the floor.

"BROTHER! I MUST INSIST THAT YOU DO NOT SLEEP DURING-" he stoped when he saw the look on Sans' face.

Tears were falling down to his basketball shorts. Papyrus froze, and Sans wiped his face with his sleeve.

"SANS...? WHAT'S GOING ON...?" Papyrus said soothingly.

"i.." Sans started, "frisk... she's.. uh.."

"YES..? WHAT ABOUT HER?" He asked.

"um..." Sans paused, tears forming again with a giant wave of the sudden realization. "oh my gosh... i'm gonna be a dad....."

"W-WHAT?!" Papyrus asked nervously.

"oh my gosh!!" Sans stood up and hugged Papyrus while bawling his eyelights out. "i-i'm gonna be a dad....! i'm gonna be a dad!!!"

Papyrus stiffened. "SO... THAT MEANS... THE HUMAN IS PREGNANT?!"

"i'm gonna be a dad, pap!" Sans was crying now as he looked up to his brother. "you're an uncle.."

~~~~~~~~~~~~~~~~~~~~~~~~~~

"So what now?" Susie asked. "Don't want to hurt the kid, right?"

"Exactly..." Gaster sighed. "We don't want to take any chances with the extractor."

You held your stomach. "What about the baby..?"

"All we can do is hope that they don't have determination." Kris states. "We don't really have control.."

"You could say that again" Chara said. "By the way, you still have to tell me about those dreams."

Kris nodded and continued walking towards the exit next to Susie.

"I'm genuinely annoyed and disappointed with my son." Gaster places his hand on your shoulder. "I'm sorry he left like that."

"I'm sure Sans is just... taking a breather..." You hugged yourself again. "So don't be sorry... this may end good or bad.. but either way, I know I'll love them.."

Gasters hand retreated and he lead you all back to the surface without saying another word. There was no point on doing any testing if it would harm the baby.

As you walked, Asriel tapped you on the shoulder. You turned around to face him and Chara, still hand in hand.

"So what do you think it is?" He asked excitingly.

You looked at him confused. "Think what is?"

Chara laughed quietly, "the gender of your fricking kid, Frisk!"

Your eyes went wide and you hugged yourself a third time, looking down at your stomach and softly rubbed it with your thumb.

"I don't think it matters." You said, smiling to them. "Maybe fate has better plans for all of us now that were all together again."

Asriel shrugged and you continued walking towards the elevator.

"Thank god there wasn't a test on me." Susie said, laughing again.

Gaster snorted and turned to the monster. "I'm still going to have to see if you have determination in your soul, Susie. So don't get your hopes up."

You heard her gulp. "Always. If only Kris, Frisk, Chara, and I were the only ones supposed to be tested on, how come fluff prince is here?" Susie asked.

"Y-yeah! Why did I have to come?!" Asriel screamed.

Gaster started laughing and Chara giggled nervously behind you, causing you to turn around again.

Her face was beat red and the permanent pink glow to her cheeks was brighter. You had the urge to say 'awe', but you didn't.

"Ask princess Chara. She's the one who told me she wouldn't do anything without you here with her." Gaster said.

Chara laughed nervously again. "T-that's not funny.. I-I don't know why I'm laughing."

Asriel hugged her "At least I'm not the only one who was scared.."

"I WASN'T SCARED!!!! C-crybaby!" Chara shouted.

Asriel laughed and hugged her tighter.

"what am i gonna tell tori?!" Sans asked in a panic.

"BROTHER! CALM DOWN!" Papyrus interrupted "IM SURE QUEEN TORIEL WILL-"

"she'll kill me. that's what she'll do!" Sans shouted. "we just got engaged! it wasn't supposed to happen this fast."

"BROTH-" Papyrus tried speaking again.

"and what's with the baby growing so fast?! only monsters grow that fast in such little time! and I know for a fact that frisk isn't a monster!" He was pacing back and forth in the living room, waving his hands around as he talked.

"SANS.." And again...

"and when did she get pregnant?! that's my question!" Sans kept going.

"SEEMS TO ME THAT YOU HAVE AN ABUNDANCE OF QUESTIONS..." Papyrus whispered to himself as he sat on the couch.

"how am i going to tell toriel that her daughter is pregnant?!" He asked. "oh gosh.. what's asgore going to do to me?! it's official!!!! i'm gonna die a fiery death!"

"YOU'RE OVERREACTING..." Papyrus said.

He placed his hands on his head and breathed in and out slowly. Then he reached into his pocket with his left hand and pulled out his phone.

"WAIT.. WHAT ARE YOU DOING?" Papyrus stood up off the couch.

"calling tori. gotta tell her." He said.

"WOAH THERE!" Papyrus grabbed Sans' phone from him. "YOU SHOULD TELL HER TOGETHER! YOU AND FRISK ARE PARTNERS, AND THERE IS NO 'I' IN PARTNERS."

"...." Sans just stood there, staring at his brother.

He wasn't a kid anymore.. Papyrus was all grown up and Sans couldn't except it for a long time.

"you're right." He smiled and hugged him. "you're so cool, bro..."
