Kiara's POV

We landed on the hard floor. The room was pretty dark.

"Ow..." I muttered as I rubbed my head. "The machine should really stop landing us on really hard surfaces."

"i agree. i might accidentally die." Sans said. I stood up first and saw that we were in a very familiar lab.

"Oh my gosh. Are we back home?" I gushed excitedly.

"i don't think so. look." Sans pointed in a monitor and I followed it. It was the Core Project being constructed.

"Oh shit." I muttered under my breath. "We travelled to another timeline."

"is somebody there?" A voice like Sans asked as a door opened. Lights flickered and I squinted at the sudden light. I heard a gasped and I turned my head towards the door. It's Sans younger version but in his teenage years. He was wearing the exact same thing Sans is wearing right now.

"why do you look like me?" The Sans who entered asked as he walked over to my brother. I decided to hide in the shadows since I'm pretty sure Gaster will appreciate that.

Sans looked at me questioningly and I gave him a look that says 'don't let him know I'm here'. He nodded slightly and stood up.

"i should ask the same as you." He said. I chuckled a little because there wasn't any difference. Seriously. They're just the same height!

"i think you're an impostor." The other Sans said bluntly. I nearly laughed out loud but put my hand over my mouth.

"i'm not an impostor." My Sans replied, adjusting his glasses. Oh, I see were this is going. "let's go get dad then."

"agreed." They both walked towards the door and Sans mouthed 'I'll be back' before he completely shut the door.

I went out of the shadows and sighed. This is gonna be so hard.

"Hey." A voice said and I turned to it's direction. I saw the curtained area where I use to stay. From there, a small me was poking her head and looking at me.

"Hey." I walked over her and got in the curtained area. There, my old bed and desk were contained. The large monitor was fixed against the wall and the other wall was covered with books. Yup, definitely my old bedroom.

"Why are you here?" The younger me asked. She was wearing a black dress. The black dress Gaster gave me back then.

"A certain machine malfunctioned and we landed here." I said, careful not to spoil that Gaster will be falling at the core at around five in the afternoon. Speaking of time...

"What time is it right now?" I asked.

"Four o' clock." Gosh. One hour till death. I cried a little as I sat down the bed. The younger me looked at me worriedly as she rubbed my back.

"Hey, what's wrong?" She asked me with a concerned look on her face. I laughed while crying. I don't care if she thinks I'm mental.

"I can't tell you! All I can say is something bad will happen later!" I told her and laughed again while crying.

"Uh, keep laughing all you want? Maybe it will stop your increasing insanity?" The younger me's comment made me laugh harder. I think I'm already insane.

My laughs reduced as I cried in a pillow. The younger me was sitting beside me, looking uncertain.

"You're future me, rigth?" She asked and I nodded. Her eyes sparkled. "How was the life outside? Is it nice? Was the air warm?"

Her curiousity reminded me of everytime I ask Gaster if I can go out. He will always say no but I hope that it would happen.

I sniffed and smiled at her. "Yeah, it was nice. There's different places all over the Underground. Here, it's called Hotland. It's hot outside but it's air-conditioned here inside. The next place is Waterfall. The temperatures perfect and lots of shiny stone littered across the ceiling of the Underground there's plenty of Echo Flowers scattered all over the matsh. Then there's Snowdin. It's really..."

As I kept telling her all the places, her eyes showed excitement.

"Oh! I wish I can go outside!" She gushed.

"Someday you will. I am future you, right?" I said. My tears were already gone. The story telling was really helpful.

She nodded as answer to my question and I ruffled her hair. I know she likes it like that. I mean, I am also her, right?

We heard a lot of footsteps rushing to the room. She quickly looked at me.

"Quick, under the bed." She whispered. I nodded and opened a latch under the bed. Probably wondering how that ended up there? Told you I have plenty of secrets.

"i am the real sans." I heard a Sans said.

"no, i am." The other one argued.

"Would you two shut up?!" Gaster's voice boomed. I didn't flinch because I'm kinda use to the ranting. I've been in the void with Gaster, for Asgore's sake. I wanted to get out of the latch and comfort my younger version since back then I wasn't use to the loud sounds.

"You two stay right here while I check on something." Footsteps towards us was heard and I could sense it was Gaster's. He slipped into the small curtain portion and sat on the bed.

"There, there, I'm sorry for shouting." Gaster consoled the younger me. I can hear her sniffing. The younger me's sobs slowly began to disperse.

"Dad, there's an older version of me under the bed." I was kinda puzzled. She made me hide then she's gonna tell Gaster? This is so f*cked up.

"What?" I took that as a cue to get up from under the bed. I stood and dust off some dust and lifted my head to Gaster.

"Hi."
