Sans stared wide-eyed at the sky, his little hand reaching up for his father's brown suit sleeve. He made a small sound.

Stars and galaxies spread out above him like a painting. He pointed with his free hand and his father smiled.

"What are those called, Sans?" Gaster asked quietly.

"Stars, right Dad?" Sans breathed. Gaster chuckled and rubbed his bony fingers on Sans's skull. He nodded.

"We should get home, buddy," Gaster said as he picked up his son. Sans's eye sockets were heavy with exhaustion as Gaster walked back in from the Ruins. "Aren't you glad that there's still a hole for us to see through?" Sans could hardly manage a nod as he drifted off to sleep.

Sans awoke in his bed, hearing Gaster's muffled voice from downstairs.

"Thanks for watching Papyrus, Undyne," Gaster said.

"No problem, Dr. Gaster!" a rough voice replied. "He's such a sweetheart, but boy is he energetic!" Sans heard the sound of the front door closing and his door opening.

"Hey Sansy," Gaster cooed. "Sorry if we woke you, bud. I'm just gonna put Pap to bed, then it's lights out."

Sans scooted over in his bed to make room for his little brother, patting the mattress beside him tiredly. He felt the weight of Papyrus beside him and smiled as the little body curled around Sans's arm.

"Goodnight, Dad," Sans yawned as he turned over to face his little brother. The door shut and Papyrus sat up, blinking his eye sockets. His right one glowed orange.

"Sans," Papyrus whispered. "Where's my jammies?" Sans looked down to see Papyrus still wearing his overalls. "I'm all uncomfy," he whined.

"Here, get up so I can help you into them," Sans whispered as he nudged himself around and off the bed. He landed with a thud.

"Lights out, boys!" Gaster shouted from downstairs. Sans winced as he grabbed Papyrus's hand and led him over to their dresser.

He opened the bottom drawer and stood on top of it, then stretched his arm to open the top cabinet. He felt around with his hands until they landed on Papyrus's soft pajamas.

"Can I have the ones with the rockets on them?" Papyrus asked quietly.

Sans squinted at the ones he'd grabbed. They had dogs, not rockets. He reached back up into the cabinet, muttering a quick yes. He grinned as his hand found the other ones; rocket ship decorated orange pajamas.

"Do they have the feeties in them?" Papyrus whispered. Sans nodded and carefully climbed down, shutting the drawers on his way.

"Take off your overalls, okay?" Sans unzipped the pajamas as Papyrus struggled with the buttons. He sniffled.

"I can't get it," he sniveled. Sans undid the buttons easily and worked his brother out of his clothes. Papyrus clumsily pulled his shirt over his head and handed it to his older brother.

"Let me see your arm," Sans ordered. Papyrus lifted up his right arm for inspection. A while back, he had slipped and fallen, leaving a dent in the bone.

"It doesn't hurt as bad," Papyrus insisted as he grabbed for his pajamas. He pulled them on, not taking Sans's many offers to help.

"You sure you don't want me to-"

"I'm a big boy!" Papyrus protested. "I can do it!"

"But the arm doesn't go over your- here, let me," Sans fixed the pajamas and pulled the hole over his brother's skull.

"Boys!" Gaster's voice could be heard downstairs. "One more time, lights out!" Papyrus flinched and moved instinctively towards his older brother. Sans zipped up the pajamas.

"Hey-"

"Shhh," Sans hissed. "Don't make Dad come in here." Papyrus nodded as Sans lifted up the tiny skeleton.

"I'm tired," Papyrus yawned.

"I know, Pap-Pap." Sans put his brother down onto the bed and crawled in next to him. "Goodnight."

"'Night, Sansy," Papyrus murmured sleepily. The little body curled itself into Sans's stomach and Sans hugged his brother tightly. He pulled up the covers with one hand and held Papyrus with the other.
