4

You, Gaster, and Papyrus were walking back to the cells when Gaster saw Sans with the color cube. "Oh. Subject 1, give me that. I'm going to need it for later." Gaster said, you notice Sans about to grab Gaster's wrist. You teleported and shoved Gaster before Sans pulled you into the lasers.

A blast came and you hit the wall. Your shirt was burnt to where it showed your forearms and stomach. You were bleeding as you didn't breath. "SANS! ARE YOU OK?!" Papyrus asked. "Yeah I let go in ti-!" Sans saw he didn't shock Gaster, he shock you.

Gaster rushed over and placed his hand on your neck. '(Y/n) isn't breathing... no...' Gaster wrapped his arms around you as he tried to heal you. Papyrus and Sans watched as his body weakly glowed green. "Come on... co..come on..." Gaster whispered as you showed no signs of life.

That's when Gaster saw your chest glowing green. He saw a number of colors before it stopped at green. You jolted awake as you breathed heavily. "A-AHH!" You gripped Gaster as your breathing was uneasy. "HE-HELP! CA-CAN'T BRE-BREATH!" Gaster lifted you and rushed away.

Papyrus looked at Sans before sitting down by the lasers. "SANS... DID YOU MEAN TO PULL (Y/N) INTO THE LASERS?" "No. But I'm kinda glad I did." Meanwhile, Gaster made you sit on a bed next to him as your breathing stayed uneasy. "(Y/n), look at me!" Gaster ordered as he used his healing magic on the sides of your head.

You snapped out of your vision as your breathing suddenly calmed. "G...gaster?" Gaster nodded before he wiped a tear away. "How did you do that, with your soul?" Gaster asked, you looked down before your shoulders started to shake.

"I..I don't kn..know... I..I..I panicked..." You whimpered, Gaster pulled you close and hugged you. You hugged Gaster back as you whimpered. "I..it was pa...painful a..as $h!t..." You whispered, Gaster rubbed your back as you kept whimpering. "Thank you."

You leaned back and looked up as Gaster rubbed your head gently. "You may have just saved my life." You nodded and hugged Gaster. Gaster hugged you back as he sighed. "You are truly one of us." You smiled as a few tears slipped from your closed eyes.

"Th..Thank you..."
