Scarlet woke up early that morning she went downstairs and saw that Sans was on the sofa, resting his head on his fist when Scarlet got to the bottom of the stairs he noticed she was there.
"oh heya sis I didn't think ya would be up this early" She looked down to the floor and rubbed her arm.
"I couldn't sleep" Sans smiled and patted the place next to him.
"come here" She climbd up next to Sans and leaned her head against his side as he wrapped his arm around her. "What's the matter sis?" She looked away from Sans.
"I'm worried about dad's experiment today" Sans looked worridly at Scarlet.
"don't worry sis dad's thought everything through he'll be fine" Scarlet sighed and closed her eyes. Later that day Scarlet and Sans went to the lab with Gaster many of the scientists looking at Scarlet in horror or anger. Sans placed a protective hand on her shoulder and glared at the scientists Scarlet looked down ashamed.
"they have the right to look at me like that I have got the wild side" Sans looked at his sister in shock.
"that doesn't give them the right to look at you like that" Scarlet sighed and looked down at floor. "so dad where's the invention you were talking about?" Gaster looked towards a large metal door and swiped a keycard down.
"Here it is" It was a large silver cylinder with a large switch on the side. "When I flip the switch a doorway to another world will open up and we will be able to travel to wherever it opens up". Gaster flipped the switch and a large black portal opened suddenly the machine began to spark and let out a noise that was almost animalistic. Sans grabbed Scarlet protechtively and held her close in case they needed to run. Looking at his father in worry he asked.
"Dad what's wrong with the machine?" Gaster looked back at his scared children.
"I don't know..." After presssing several buttons Gaster gasped. "oh God the machine is gonna explode and it's gonna take out the entire lab" Sans ran to the console.
"there has to be a way to minimise the blast radius" Gaster sighed.
"There is but it has to be done with manual power" tears began to well up in Sans' eyes.
"No you can't do that that's suicide!" Scarlet looked worridly at her father.
"I don't care as long as you two and Papyrus are safe" Sans glared up at Gaster.
"we are not leaving you here!" Gaster sighed sadly.
"Yes you are" Suddenly Sans and Scarlet were lifted in the air and flung backwards Sans hit the wall and quickly caught Scarlet. They stood up and ran to Gaster but a large metal door blocked their path. The duo ran to the large window and slammed their fists into the glass.
"Dad get out of there!"
"Please don't leave us dad!" Gaster sighed and as a lone green tear fell down his face he pressed a large yellow button and a large white light filled the room. When the light dissapeared Sans and Scarlet gasped the machine was destroyed and Gaster was gone. Rushing inside they found nothing but a part of his labcoat that had been ripped off. Scarlet clung to it as red tears fell like a waterfall Sans let only a few tears fall so he seemed brave. Standing up Sans placed a combferting hand on her shoulder.
"Don't worry Scarlet we are gonna fix this machine and we will get dad back I promise" Scarlet sniffled.
"Don't make promises you can't keep"
