Third Person's POV

"So, what timeline are you from?" Gaster asked Kiara.

"From the timeline ahead of yours?" Kiara answered in a question, not sure if it's the right answer.

Gaster nodded. "I see."

Suddenly, an alarm sounded off. Their eyes shifted to the monitor.

"WARNING! CORE BREAKDOWN!"

Gaster looks at them. "I need to go. I must fix this at once."

Kiara knows what's gonna happen but kept her mouth shut. Gaster stood and walked out of the tiny curtained room. As soon as he left, Kiara broke down.

"Shh, it's gonna be okay..." Thw younger Kiara tried to comfort her older version while rubbing a hand on their back. Kiara began to laugh.

"I'm being a big crybaby, aren't I?" She said and laughed humorlessly. The younger her looked at her with concern etched on her eyes.

"I think you should sleep for a bit. Looks to me you haven't sleeping." Yes, that is true. Kiara hadn't sleep since Underfell.

"Yeah, I guess you're right." Kiara lay down the bed. The younger her smiled gently.

"Sleep well."

~*****~

Kiara woke up to the sound of crying. She sat up and saw younger Kiara crying in the corner. Kiara rushed to her side.

"Shh... It's gonna be fine, I-" Kiara suddenly stopped, remembering that promises are hard to be kept. "I'll try to keep it that way."

Younger Kiara hugged her and Kiara hugged back. A few seconds later, the sound of a door opening was heard.

"I can't believe he fell right in..." Younger Sans said, crying.

"I think you'll be fine." Sans replied, probably trying to calm him down.

"I don't know which Sans is which." Kiara whispered to herself. They are both alike since the Sans Kiara knows is wearing the same.

Suddenly, the world started to fall in front of Kiara's eyes. The ground started to shake.

"Oh no..." Kiara panicked. She felt someone's grip on her shirt. It was her younger version.

"W-what's happening?" She asked shakily, sobbing harder out in fear.

"E-everything's gonna be fine, o-okay? You're gonna be f-fine." Kiara was trying hard not to cry as she wrapped her hands around the other her. After a while, both Kiaras blacked out.

Sans' POV

"Uh.... So, I have somethin' to tell ya." I said. He looked up to me.

"I'm actually from.... the future timeline. The next timeline, to be exact. And I know you'll be fine." I said, not sure if I was doing things right. Geez, I'm not really good at giving pep talks.

"You're... You're from the future?" He asked. I nodded hesitantly. "Then you know this was gonna happen?"

"Uh yeah, kinda."

As soon as I said that, I was slammed to the wall as my HP drop to 0.5. My eye sockets were wide in surprise.

"Then why didn't you stop it?" Younger me has his eye glowing. Shit.

Kiara's POV

I groaned as I turned to my side.

"Hey, Kiara! Wake up!" I heard.

"Just a few more minutes Pap..." I mumbled.

"Kiara! We're in the void!"

I quickly shot up that I immediately regret cause it brought a sharp pain to my head.

"Sorry?" The younger me said.

"It's fine... But you said we're in the void?" I asked, rubbing my head.

"Yeah."

I look around. Yup. Definitely the void. It's so dark. The dark and endless room that I've been use to.

"Kiara?"

I turned my head and saw Gaster. I felt tears fall to my eyes as I ran to him. I hugged him tightly. He returned the hug. After a few minutes, he pulled away.

"What are you doing here?" He asked. I noticed that the younger me vanished.

"I was with Sans in the past timeline and somehow I ended up in here." I explained. "What happened to the other me?"

"She vanished, since the present you is here."

"Do you think you can bring me back there?" I asked again.

"I believe I cannot. I could only bring you back to Undertale." Gaster said sadly.

I thought it through. I may try to bring Gaster with me...

"I have an idea, Dad. Let's try to teleport back there." I said.

"That is dangerous! You might truly end up like me!" Gaster protested.

"Welp, it's worth a shot." I winked. I grabbed his hand.

"I do not think this will work." Gaster said unsurely.

"Trust me this one time, Dad. Please?" I pleaded. He looked straight to my eyes and sighed.

"I guess there is no stopping you. Let us do it." He smiled. I smiled back and activated my magic. Gaster activated his magic too. I took a deep breath as I closed my eyes.

"Okay, here we go." I set my focus on teleporting as I use mine and Gaster's magic. As I think of teleporting to my room in the Lab, my head hurt. I screamed.

"Kiara?! Kiara! Stop it at once if you are getting hurt!" I didn't listen. I am determined to get us out of here.

I used all my strength to take us to that timeline.

Then, I blacked out.

Everything is messed up, isn't it?

Well, it was only partly my fault.

Tra la la

I know you're there. And the author does too.

Well, I wouldn't be spoiling some things. See you next chapter.
