*Sans*

great. now i have to stay at that jerk's house. i followed UF Kiara grumpily while Kiara was beside me.

"It's okay, Sans. It might not be that bad." Kiara told me.

"Yeah, Edgy's nice when ya meet him. And his brother's not much of a threat." UF Kiara agreed. i shrugged.

"we all know i'm gonna have a bad time here." Kiara smiled at me apologetically.

we arrived at the jerk's house. UF Kiara knocked.

~*****~

*UF Sans*

i lazily stood up from the couch annoyed. i opened the door with a bang.

"i f*cking told yo-" i stopped when i saw Kiara, the other Kiara and dopperganger. he looks mad.

"Uh,hey Kiara. what do you want?" i asked. she smiled at me sweetly.

"Can Undertale Sans please stay here for a week or two? He needs a place to stay." she asked me. i looked at her like she was insane.

"are you f*cking serious?! i can't even stand a damn f*cking minute with him and you expect me to let him stay here? f*ck no."

"Aw, Edgy please?" Kiara and the other her pleaded in unison. i sighed annoyed. well, who can resist Kiara?

"fine. but don't expect me to treat him nicely." i gaved in. Kiara smiled and hugged me.

"Thanks bro."

"Yeah, yeah, sure now go away." i told her and they teleported. so it was me and Undertale Sans left. i ignored him and sat back on the couch, continuing watching the tv. other Sans cleared his throat and sat down at the other side of the couch. it's better this way so we wouldn't have to fight or sh*t.

*Kiara*

"So, this is the cave?" I asked my counterpart. She nodded.

"Yup, complete with the monitor, bed and massive junk of papers." I giggled at her introduction.

"Definitely the cave." The cave looks the same except that it was more of a black and red theme. Mine was like blue and black.

"How's life here?" I asked her.

"Well, it's really noisy most of the time. Monsters getting killed in front of you, being criticized 'cause you're human and some other sh*t like that." I flinched at the part of monsters getting killed in front of you.

"Isn't that a little gruesome or what?"

"Yeah, mostly it is. But most of the time it was Paps who kills them. Edgy wouldn't frequently do it. It was sad to see them not get along. They always fight at home. I was supposed to live there but due to their misunderstandings, I told them I'd find my own house." She sighed and looked sad. Then she brightened up a bit. "Hey, how about you tell me about your life at your universe."

"It's mostly the void, if you know what I mean." She nodded.

"Gaster?"

"Yup. So I was sent to the timeline so I can watch their movements and watch my sister, Chara if she's going to kill. Suddenly, a reset happned and I was known as the skelebro's sis. Apparently, Paps died because of Sans' Gaster Blaster and Chara. Sans had a mental breakdown and passed out so I left Chara and teleported me and Sans to the cave. I made the machine with Sans' help and it malfunctioned."

"So Chara's evil at your universe? Here she's as sweet as an angel." She said. I sighed. I know Chara's good here.

"Yeah. Sometimes I wish she was like your Chara in our universe."

"Hey, how about you change to pajamas? After all, it's already night." She offered. I nodded.

"You know what? I thought of something. What if we both wear the same clothes and get them confuse? Well, technically we are wearing the same colored hoodie and all but act like we'ee the same person?"

"Actually, I think that' a good idea." She smiled. "Let's do it tomorrow."

*Third Person*

UT Kiara and UF Kiara walked together towards Snowdin, their moves synchronized. As they reach the end of the forest, they turned to each other.

"Ready?"

"Ready."

They walked towards the skelebro's house and heard shouting. UF Kiara sighed while UT Kiara looked at the front door worriedly. UF Kiara opened the door and they both came in.

Inside, UF Papyrus and UF Sans were fighting physically and a confused and terrified UT Sans was seating at the couch unsure of what to do.

UT Kiara quickly went to UT Sans.

"Which Kiara are you?" UT Sans asked, noticing that her and the other Kiara were wearing the same thing.

"Undertale." UT Kiara answered. "What the hell happened here?"

"they were upstairs. when they got down, UF paps threw a bone at UF sans and they both end up fighting."

Suddenly, UF Papyrus and UF Sans were lifted from the ground.

"Stop it, will you?!" UF Kiara shouted at them annoyed. "I don't know what the hell happened here but both of you are so childish! Fighting like this everyday, don't you get enough? You're both getting on my nerves!"

"The damn fool started it!" UF Papyrus reasoned.

"i didn't! you're the one who always starts it! calling me lazy, incompetent, idiot, pathetic and a bastard!" UF Sans defended.

"It is true! You are always lazing around doing nothing!" UF Papyrus shouted back. The two continued bickering until UF Kiara sighed and sat down the couch. The Underfell Skelebros were still fighting inside and floating in the air.

"are they always like that?" UT Sans asked UF Kiara.

"Yup, I have to make them float like that till they stop their bickering so they wouldn't have to fight."

"They're definitely boneheads." UT Kiara whispered to UF Kiara with a slight glare at the Underfell bros. UF Kiara giggled.

"Yes, yes they are."
