The Third Child

by Amaterasu Verdana

Sans is sitting at his sentry post making a hotdog, and finds a crying woman. An incident in the bathroom leads to a final battle. Through these events Sans realizes that the Third Anomaly has appeared. But will he end it's life and put a stop to the timeline changing? Or will he fight alongside them to defeat a greater threat?

"Undyne, what was that?" Papyrus asked, looking confused.

"I don't know, Papyrus. Has that happened before?"

"Yes, actually, it has, when, 'you know' happened."

"Well, we should check on them."

"Yes, definitely."

Moments later, Papyrus and Undyne were standing around the remains of Sans' "secret back room". Undyne noted that the room was charred, and the same mark from earlier was charred in the floor. Standing on the mark was a slender lady. She had fiery red hair tied back in a ponytail, red pointed dog ears on her head, shining yellow eyes, and facial markings. She wore a simple white kimono with golden trim.

"Who are you?" Undyne called out to the figure.

Movement in the rubble. Sans's hand shot out of the rubble, the sleeve of his hoodie in tatters. He pulled himself up, and pushed another block near him to the side. Alphys was laying there, bruised, with multiple pieces of debris lodged in gashes along her scales.

"Oh my god! Is Alphys okay?" Undyne gasped, horrified.

"She'll be alright. I told her to get down as soon as I sensed the energy building. Pap, you should take her into the house." Sans said, sounding exhausted.

"Okay, brother." Papyrus replied, walking over to the pile of rubble where Alphys lay, unconscious, bent over, scooped her up, and with her in his arms, walked back around the house and entered the front door.

"Anyways, who are you?" said Undyne, quickly changing the subject.

"My name is Ammy. I had to come back. I saw what happened. And Sans, sorry for blowing up two rooms in your house." Ammy said, sounding guilty.

"S'fine. After all, I can just rebuild it, can't I?"

"Publicity, Sans. Publicity. How can you forget other people are going to start asking questions?"

"Oh."

"Hey, what's your name?" Ammy asked Undyne.

"My name is Undyne, and I'm the Captain of the Royal Guard."

"That's nice to know."

"Hey. Ammy. I want to fight you."

"W-What? Why?" Ammy asks, shocked.

"I wanna see how strong you are."

"Oh. Ok."

Writer's Note: More cliffhangers. I just want to let you know that maybe I could, y'know, start to recommend music for you, the reader, to listen to. I'd like to recommend Judgement by TryHardNinja. It's an Undertale fan song from Sans's perspective, and it's a great song. Just go onto YouTube and search, "judgement tryhardninja". You can capitalize if you want.
