Night had fallen on the surface. Gaster purchased a box of spider donuts for the air, however long it would be. The skeleton grabbed a donut and took a bite. He investigated the donut. "She doesn't call them spider donuts for nothing," he stated as he pulled a stray spider leg from the donut.

A door appeared in front of the table. "Dad, me and Frisk are here and ready to talk!"

Gaster was startled as he heard the loud voice of Papyrus. He dropped the spider donut on the table. "Ah yes. Thank you for coming."

Papyrus and Frisk took a seat in front of the scientist. Frisk took a donut and began to nibble on it. "So Dr. Gaster, what happened then," Frisk asked. Two sets of eyes were focused on Gaster.

Gaster let out a breath of air. "I admit that what I did that day, was not something I should have done, but I had good intentions. You are aware of Sans' frailty, correct?"

Frisk and Papyrus nodded. "Yeah. Sans has never had more than one hp," Papyrus confirmed.

"I was so scared, so scared that one day I'd come home and find a pile of dust," Gaster muttered. "Like what happened with Calibri."

"Calibri was your wife," Frisk guessed.

"Yes." Gaster looked to the ground. "Calibri was a gentle soul, and I absolutely loved her. Unfortunately, her family has a condition with their stats. The condition doesn't affect everyone, but she suffered from it. There was nothing I could do for her, so I turned my eyes on Sans. I already knew that he had the condition, and I couldn't bear to lose him." He looked at the table and played with the spider donut he dropped.

"So I have a mom too!? Or… I had one," Papyrus muttered.

Gaster smiled warmly. "She was always so happy."

Frisk grinned."Awwww!"

Gaster sighed. "I'm getting off-track. I was nervous that day. I didn't want to do anything to hurt him, but my desperate wish to make him stronger consumed me." He clenched his hands. "I wasn't thinking clearly. Her death was still fresh in my mind, although I had the Sans forget, for his protection. All I cared about was helping the two of you, Papyrus, but something happened. The liquid determination, the small amount I put in the formula, had a negative effect on Sans. It hurt him. Monsters were never meant to have even the small fraction of determination I placed in the needle. He was screaming, and he was terrified of me. I might have said something about you, and he lost it." He placed his hands on his skull. "I was scared to lose him. I was scared to lose you too. So I… increased his gravity and put him to sleep. Later on, I messed with his memories again, so that he wouldn't be scared of me, and what I did. I know it was wrong, and I regret it. It didn't even have the intended effect. Instead, it caused him to be able to negate rules of battle. Instead of giving the opponent a period of rest once they were attacked, Sans could now link the damage together. He could also predict attacks and use that knowledge to dodge," Gaster explained.

Papyrus grinned. "I knew you must've had some explanation!"

"I've always wondered if I did the right thing. And still, I'm not sure."

"Well, now that you've explained it to us, we probably have to tell Sans," Frisk stated. She rubbed her chin. "But how?"

"I don't think he would like to know that we snuck out," Papyrus muttered. "I mean, he made the blasters circle the house.

Gaster frowned. "You snuck out to see me?"

Frisk nodded. "Yeah! I mean, we needed to know what happened and so does Sans."

"Shouldn't you be in bed Frisk? Don't you have school tomorrow," Gaster asked.

Frisk looked to the side. "Maybe…"

"Now how would Toriel feel about that," Gaster asked.

Frisk frowned. "She wouldn't like me being here, but she also likes it when I do good deeds."

"Go back home. Tomorrow while you're at school, I'll see if I can talk with Sans," Gaster insisted. "Don't get in trouble with Toriel for my sake," he scolded.

Papyrus spawned a door. "Right this way Frisk! I uh… forgot that you need to sleep. I shouldn't have taken you out with me." He grabbed Frisk's arm. "Bye Dad! See ya tomorrow!"

Gaster waved goodbye to the two. Once the door was gone, he sighed and took a donut out of the box. "Looks like I'm sleeping Underground tonight." He placed the donut in his mouth and created a grey door. He grabbed the box of donuts and walked through. He shut the door using his elbow.

"Hey Asriel," Chara said softly. She shook the sleeping form of Asriel awake.

"Nnnn go to sleep," Asriel groaned.

"Bro, this is important. Have you seen Frisk?"

Asriel sat up. He shook his head and yawned. One of his ears landed in his mouth. He brushed his ear aside. "No, I haven't. I think she was talking with Papyrus earlier though."

Chara groaned. "I was gonna ask about what we were gonna do for the Science Fair. We've completely forgotten about that."

"Well, to be fair, we did just get our dimension broken into and now there's this drama with Sans, Papyrus, and Dr. Gaster."

"That is true."

Asriel stretched and rested his head back on his pillow. "Whatever we do, we can decide tomorrow. Go to sleep."

Chara frowned. "Fine." She got into bed and stared at the wall where she followed the wood's swirling pattern until she fell asleep.

And done! So uh... the children do have a bedtime... and they still have school. This has just been a very eventful weekend. Anyway, I hope you enjoyed this chapter. Bye guys!
