~~~Your POV~~~

I was walking down waterfall exploring it more and practicing my magic. So far I have been able to not only summon more things, but keep it secret from Frisk! Who was actually hanging out with Papyrus today. I had wanted to tell G yesterday that Frisk finally got here, but he wasn't there. 'Must have left with Error.' Was my thought when I couldn't find him. I stopped my magic as I passed by a waterfall. I sighed in content as I listened closely to the water crash down.

"Hoi!" I heard someone say under me. I looked down to find a dog-cat thing. It wagged it's tail and started vibrating when it saw me look at it. "HOI! I'm temie!" It said smiling! "Hooman! pet tem?" I smiled softly and kneeled to it's height.

"Hello temmie, and sure i'll pet you." I said and pet Temmie. It closed its eyes in content and purred like a cat as I pet it. I chuckled at how adorable it was. "ACHOOO!" I sneezed, the sound echoing in the cave. It clearly scared Temmie as the creature jumped in surprise.

"OOHH NUUU!! Hooman allrgic 2 Tem!" I said in distress. I laughed at this.

"It's fine Temmie."

"Hooman shuld come to Tem vilage!" It suggested vibrating wildly. I nodded making it vibrate even more. "YAYAYA!! Hooman! follow Tem!" It said and started walking away. I followed it to Tem village.

Once we got to the entrance I was then met by a silly, yet catchy, song playing in the background. 'Weird, this has never happened.' I thought, but shrugged it off. "HOOMAANN!!" I heard a bunch of voices say all at once surprising me. I jumped and looked down to see a group of Temmies looking up at me. All vibrating intensely.

"Hello." I said and waved at the Tems.

"HOI!" They all said at once making me chuckle. "Yu a hooman, ya?" One asked.

"Yup."

"YAAYY!!" They all said and jumped on me making me fall over. "Hooman pet Tem!" One said. I laughed at them and started petting them each on the head.

"The hell?" I heard a voice say. I sneezed and looked up to see...

"Underswap Papyrus?" I said confused and sneezed again. I rubbed my nose with my hand and looked back up at the orange hooded Papyrus. "The hell are you doing in Undertale?" I asked, he just gave me a weird look.

"Undertale? Maybe that's why Alphys was.." He mumbled the last part, but was clearly about Alphys. I sneezed again.

"Hooman, are u okey?" One of the Temmies asked me making me look at them. I smiled at their cuteness.

"Yeah, I'm just allergic to you guys. Can you get off of me for a bit?" I asked nicely. All the Temmies nodded and got off me allowing me to get up.

Once I was up I dusted myself off and looked back to US!Paps. "So how's you end up here?" I asked him. He glanced at the Temmies nervously then looked back to me.

"Uuhh.. Error." Was all he said, but that was all I needed.

"Let me guess. You were fighting Error, got into the Anti-void again, and he sent you through the wrong portal." I asked crossing my arms and a raised eyebrow. He nodded in response. I sighed and facepalmed. "Okay, well Error probably doesn't realize it or else you wouldn't be here. In fact how long have you been here?" I asked him.

"Eh, about a few hours. I was thrown into Waterfall and tried to get home but when I realized everything was different I decided to explore and found this place." He shrugged then pulled out packet of cigarettes. He stuck one in his mouth and lit it with his magic.

"Well you're going to need a place to stay until I can either get in contact with Error or he realizes your in the wrong universe. Come on." I said and started walking out.

"AAWWW! The hooman is leving Tem?!" A bunch of Temmies said sadly. I looked back and smiled softly.

"Don't worry I'll come back another time." I told them.

"YAAYY!!" They all cheered. US!Paps just gave them a weird look.

"Come on." I said and walked out the cave towards Snowdin, US!Paps following me nervously.

~(Later at the front door of Sans' house)~

I stood at the front door about to knock. 'Wait Papyrus doesn't know about the different Universe's, Frisk probably doesn't either unless Chara told her, and Sans will most likely flip his shit when he see's US!Paps.' I thought and stopped my action.

"What's the hold up?" US!Paps asked me. I turned to face towards him.

"Okay, so my Sans will most likely flip his shit, and this Universes Papyrus doesn't know about the different universes. So I'm going to need Sans to meet you first and get ready before you meet your double." I told him. He gave a confused look but nodded anyways. "Okay go to the back of the house, to the secret basements door, and wait there." He nodded again and started walking that way.

'Okay, now to get Sans.' I thought and looked towards the front door once US!Paps was out of sight. I opened the door and looked in. Papyrus and Frisk were watching MTT on the couch while Sans was asleep on the floor. I chuckled at his weirdness, but shook my head reminding myself of my small mission. I walked toward Sans.

"AH! OLDER HUMAN! HAVE YOU COME TO WATCH MTT WITH ME AND THE SMALLER HUMAN?" Paps asked. I looked at him with a soft smile.

"Sorry Paps, not now, maybe later. I need to talk to Sans though." I told him. His smile faltered for a second, but returned instantly.

"THATS OKAY HUMAN, MAYBE NEXT TIME." He said. I glanced at Frisk, who was wiggling her eyebrows and had a sly smirk on her face. I blushed, but quickly looked down at Sans who was still asleep.

"Sans." I said and slightly kicked him. Nothing.

"Sans!" I said again and kicked him again, just a little harder. Still nothing. I frowned, but thought of an idea.

"Okay, if your not going to get up, I'll just go dump all the ketchup down the drain." I said and started walking towards the kitchen. Almost instantly my soul came out in blue and I froze.

"You do and, kiddo, you will have a bad time." I heard Sans threaten. I giggled.

"Okay, okay. I won't, but I do need to talk to you in quiet. So can you let my soul go?" I asked him.

"Could've just said so." I heard him mumble as his magic let me go. I turned to him with a smile.

"Good, follow me this way."

We were at the side of the house when I turned to him, making him stop and face me. "Now don't flip your shit. Okay?" I told him. He raised a bone-brow in confusion.

"Oookaay, but why?" He asked. I just sighed.

"Come out Swap!" I yelled towards the back of the house.

"Do not call me 'Swap'." I heard US!Paps say as he walked around the corner but stopped immediately, eyes widened. I looked at Sans whose eyes were widened as well.

"P-Papyrus?" Sans asked confused, but started laughing. "O-Okay Seven, you've got me. You really tickled my funny bone, you even got Paps to join in this joke. I must give you a hand on that one." He said and literally gave me his hand.

"Your no cake walk either. The hell is this, uh.. 'Seven' was it?" US!Paps asked making Sans take a step back in surprise. I giggled at this and handed his hand back. He took it and put it back on.

"Well Seven, care to explain to me now?" He asked me as he looked at me without any pupils. I chuckled nervously.

"That's Underswap Papyrus." I stated.

"How did he get here?"

"Error accidentally threw him in our universe when the two were fighting." Sans pupils came back as he gave a confused face.

"Fighting? Why?"

"I was trying to get MY Sans back from that kidnapper." US!Paps said coldly, making us both look at him. "In fact, I believe it was when I was trying to get him back from that glitched Asshole when I first met you." I paled as Sans looked at me.

"You met him before? When?" He asked then looked back to US!Paps.

"She was in the Anti-void, was it?, she had the flame eye, like when I use my power, and seemed to be in pain at the time. She was also with another Sans at the time and they said they needed My Sans in order to 'help' her. As she told me." US!Pap said. 'DAMNIT MAN!' I thought in my head as my eyes widened.

"Seven." I heard Sans say in a dangerously calm tone. "Is what he said true?" Sans asked and looked at me with a his eye slightly ablazed. He. Was. Pissed. I quickly summoned a small smoke grenade.

"Sorry guys!" I said and threw the small grenade onto the ground, causing the entire area to be covered in smoke, and bolted. "Talk it out!" I yelled to the coughing skeletons as I ran away from the two skeletons.
