Asgore walked over to Alphys. "Did you just see that?" He asked the anthropromorphic pangolin.

"You better bet all anime I did!" Alphsy chuckled.

"You know what this means?"

"Revenge?" Alphys asked as she remembered Sans (and Asgore) poking fun at her for liking Undyne.

"Revenge." Asgore confirmed as he remembered Sans (and Undyne) poking fun at him for liking Toriel.

"So, what's the plan?"

"How about we…" Asgore began whispering to Alphys

Sans was sitting down as he watched Undyne and Papyrus wrestle, trying to find out why he was feeling strangely.

"Hey lover bones!" Alphys called.

"excuse me?" Sans inquired

"We know you like her!" Asgore yelled.

Sans walked over to them saying, "what are you implying?"

Alphys giggled before the two children began, "Sansy and Frisk are sitting in a tree!"

"knock it off!" Sans shouted

"K-I-S-S-I-N-G!" The two ignored him, enjoying how he began turning blue in anger.

"i said quit it!"

"First come love, second come the marriage-"

"I said stop!" Sans yelled, his eye flaring blue and bones appearing.

"Sans!" Chara's voice resonated throughout the house. "Come over here right. Now!"

The children involved stayed quiet, afraid of how angry the seemingly friendly human was as Sans began to shuffle over to where Chara was. When he looked up he was expecting anger, but Chara looked very sympathetic towards him. She squatted down to meet his eye level. "Sans, you are very powerful." She took his hands in her own.

"uh yeah, dad's talked to me about keeping it under control."

"And yet it nearly sliped out of control today."

"i'm really sorry! but, asgore and alphys started it!"

"Did they now? What woudl make them start it?"

"w-well, uh…okay, i might've started it…"

"With what?"

"i made fun of both of them because asgore has a crush on toriel, and alphys likes undyne."

"Well, now you know how they felt when you did that to them."

"yeah." There was a pause. "so, can i go now?"

"Oh no, I still have to enstill a punishment for you all."

"punishment!?"

"Yes, Mr. Pun Master. I will make sure that you all do your punishment. You will write a letter apologizing to Alphys and Asgore about almost losing your temper, and making fun of them in the past." Chara stood up. "Now, I want you to write in that chair," she pointed over to a child's chair at a small desk, "and you won't come up until I've approved your letter."

"aw, c'mon teach!"

"You come on Sans. Unless you want me to tell your father about this?"

"no no no! i'll do the letter!"

"Good, now get to work Sans. I'll have Asgore and Alphys in here shortly." Chara walked out to check on Papyrus and Undyne's wrestling match while Frisk looked over to Sans.

She smiled softly as she noticed he hit the back of the crayon with his chin, wondering what to write. He's got a cute nervous habit. She thought.
