Undyne and Papyrus walked through the town. Humans shot the pair wary glances as they passed by.

"So Papyrus, where do you think they have the most grease at," Undyne asked.

Papyrus felt like he was going to be sick. He glanced at the ground and avoided trying to listen to Undyne.

"Papyrus," Undyne yelled. "I think I see one!" He grabbed Papyrus' cape and began to run down the road.

"Undyne," he shouted.

"You were just standing there, so I obviously had to drag you along! Fuhuhuhu," Undyne exclaimed. While she ran, the cape began to pull away from PApyrus.

"Undyne! My cape's trying to escape," he shouted between screams.

Undyne didn't hear it, however. She kept running.

"Undyne! Stop," Papyrus exclaimed.

The cape pulled itself. Papyrus fell to the ground, as did Undyne. She dropped the cape as she fell.

Papyrus rubbed his head and looked towards Undyne. "I was trying to tell you that my cape was coming loose," Papyrus explained

The cape began to fly away.

Papyrus stood up and chased after it. "No! Come back!"

Undyne's eyes widened. She got up and chased after the cape with Papyrus. It flew high into the air and disappeared over a house.

"Nyoo hoo hoo," Papyrus cried. "My cape..."

"Sorry Papyrus. I didn't hear you." Undnye looked at the house. "I'm going to look for your cape," Undyne said. "You go ahead and look for a place to eat." She ran towards the house. People screamed as she ran past at high speeds.

"W-Where am I," a monster asked. He rubbed his head and looked around. He gasped. "This place is really pretty!" He smiled at the sky. "Oh man! Everyone back home would have loved this," he cheered. His eyes gazed down at the pavement.

"Home..." He clutched his blue cape his hands. "I wonder how everyone's been doing." He shook his head. "No. I'm sure they've been great! The Magnificent Sans cannot be so sad!"He stood up. "Yeah! And once I get back to my friends and family, I'll tell them all about my adventures, including this cool place!"

A red cape fluttered in the wind above him. "What's that?" He used his blue magic to bring the cape towards him. "A red cape? Who wears those?"

A dusty cloud appeared in the distance. It came closer and closer.

Sans(?) squinted at the dust cloud. "Is someone running this way?"

The cloud came even closer. He could make out a figure running in front of it.

"Is that... Dr. Undyne?"

Undyne stopped in front of him, although this Undyne did not look like the Undyne he knew. She looked more like Alphys. She gave Sans(?) a weird look.

"Sans? Why are you wearing that?"

"Why would you ask that? This is what I, Sans the Magnificent, always wear," Sans(?) cheered. "Why are you dressed like Alphys?"

Undyne glanced down at her clothes. "What the HECK are you talking about Sans?" She studied the skeleton.

"Uh... Undnye?" Sans(?) shrinked back. "You're kinda staring at me."

"UNDYNE," Papyrus shouted. He ran towards her. "Undyne, I wanted to help you look for me," he started. He looked over at Sans(?). "My cape!" He took if from Sans(?).

"Papyrus," Sans(?) questioned.

Papyrus grinned. "I see that you've finally picked up on my special style! Now it is you who are being rubbed off on!"

"W-What? But Papyrus, this is what I always wear. You always wear an orange hoodie," Sans(?) insisted. He pointed to Undyne. "And why is Dr. Undyne dressed like Alphys?" He crossed his arms. "This is all very confusing for Sans the Magnificent."

"Sans? Are you feeling okay," Undyne asked.

"No, are YOU feeling okay Dr. Undnye? You never step foot outside of your lab except to see Alphys."

"Brother, you are scaring me," Papyrus exclaimed. "Your memories seem to be backwards, but don't worry! I'm sure my homemade pasta will help to jog your memory! Perhaps maybe Lady Toriel will make you some pie as well!"

Sans(?) gasped. Stars filled his eyes. "You know the queen? Cool," he exclaimed.

"You're dating Toriel," Undyne said.

"W-What?" He was taken aback. "B-But I never see the queen. I've heard that she's very nice though!"

Papyrus and Undyne shared glances. "Forget the pasta, we're taking you to Alphys," Undyne insisted. She lifted Sans(?) up by the waist. "Feel free to take a nap on the way."

"Why would I do that? Napping's a waste of my time!"

"Yup. There's something wrong here." Undyne sped off with Sans(?) in tow. Papyrus followed closely behind.

Papyrus and Undyne stormed into the house, carrying Sans(?).

Toriel chuckled. "I see you've found him."

Frisk looked confused. "Sans was missing?"

"That explains why Papyrus was not yelling for us to get up," Asgore realized. "Well, I am glad you found him."

Undyne shook her head. "This isn't the Sans we know!"

"Huh," Frisk, Asgore, and Toriel exclaimed.

"Is that Queen Toriel," Sans(?) asked. "She's seems really nice!" Sans(?) gasped. "And is that a human?"

Frisk gave Sans(?) a funny glance.

"Are you okay?"

Papyrus shook his head. "Something's very wrong here! First off, he's taking my special style!"

Sans(?) scoffed. "Look Papyrus, I've always worn this. You're the one not wearing your normal clothing."

Papyrus gestured towards Sans(?). "See!"

"Don't you think this is a bit weird for me too? Look, MY Papyrus is a lazy slob who really likes to eat at Muffet's. This one seems to be just like me," Sans(?) exclaimed.

Papyrus gasped. "You're just like me and my Sans is like your me," Papyrus exclaimed. "Except, he liked to eat at Grillbys."

Alphys ran into the room, carrying a large stack of papers. "S-So I've um... I've been looking into what might cause this memory issue for Sans." Everyone looked at her. "U-Uh... I I had a little help f-from D-Dr. Gaster for this," she stated.

Sans(?) looked confused. "You mean the one who drives the boat?"

Alphys' eyes darted around the room. She smiled awkwardly. "I-I'll just get Dr. G-Gaster to explain." She ran out of the room.

"Alphys! Does this mean that you won't train me today," Sans(?) called out. "I guess that's a no. Why is everyone acting so strangely?"

Gaster walked into the room. "It would seem as if Alphys couldn't explain what happened." He walked up to Sans(?). "There's been some sort of disruption in the time-space continuum. My hypothesis is that the combination of me, Chara, Asriel, and the Author caused the very fragile barrier between universes to open up. In short, this is not our Sans, but a Sans from a different universe."

"Oh! So that's why everything's so pretty," Sans(?) cheered.

Gaster studied the skeleton. "We can't very well call you Sans, otherwise that would complicate things. What would you like to be called?"

Undyne grinned. "I've got it! With that outfit he's wearing, I've got the perfect name! From here on out, you will be named Blueberry!"

"Are you okay with that nickname," Gaster asked.

Blueberry shrugged. "It's fine with me, I guess. So if I'm in a different universe, where's your Sans?"

Hey! I'm done with this chapter! For Underswap Sans, I will not be having his text lowercase. I don't know if Underswap Sans would have lowercase text or if that was Underswap Papyrus...

Anyway, hope you guys like this chapter! Many of you were wondering what happened to the original Sans.

Hehe. It's my lil' secret! Wink!

Bye guys!
