~~~Mirror's POV~~~
I woke up and I saw I was inside a room I looked at the back of my palms and I turned and saw a chubby skeleton wearing a blue jacket and he has a worried expression stuck on his skeletal face. "Where's (y/n)?!" He asked angrily I jumped at his tone and I suddenly heard a familiar voice in my head. And it sounded angry.
"D O N T  H U R T  H I M" (Y/N) said and I laughed maniacally "oh dearie~" I said and looked back at the skeleton. His eye sockets  were empty....... Just like the void where I used to live.... "Heh. Now. Answer. My. Question." He said in an angry tone. I looked at him and then I noticed my hair wasn't (y/n)'s (h/c) color. It was grey and the end of my (h/l) grey hair was darker grey. But my skin was like hers it was (s/c) and my eyes weren't grayish anymore it was (e/c) and my hair was the only one that didn't change 'heh now I know how he knew I wasn't (y/n)' I thought to myself and the skeleton was filled with rage that I still haven't answered his question.
I brought my hand out for him to shake but he flinched when my hand reached him "I'm (opposite name) but you can call me mirror" I said and he shook my hand "the names Sans, Sans the skeleton" the skeleton said and when our hands stayed for a minute his blue jacket sleeve turned grey. He quickly snatched back his arm and when our hands de-attached the sleeve turned back to its normal blue color.
I avoided eye contact with him when he immediately puuled away and I could feel that annoying feeling I always have when I'm around people........ Sadness.
I got up from the hospital bed and went towards the mirror only to find the original (y/n), there were chains in her hands and when the skeleton er.... Sans saw her he quickly ran to the mirror.
"OH MY GOD (Y/N) I AM SO SO SORRY I NEVER MEANT FOR THAT TO HAPPEN AND I AM SO CURIOUS RIGHT NOW ON WHY YOUR STUCK IN A MIRR-" he quickly grabbed my neck and pinned me to the wall and his grip was getting tighter "now I see what's going on here Mirror you locked her up and took her body... DIDNT YOU?!" he said as his white pinprick pupils disappeared I smacked his hand that was holding my neck but his grip got tighter and his voice was deeper than ever "SET HER FREE" he ordered me and let go of my neck I gasp for air and when I had the courage to speak I sat up "I-i don't k-know h-how we were just t-talking b-back f-from w-where I w-was trapped but when I opened my eyes I was here" I said and I had this weird feeling inside of me that wants me to run....... And that feeling was fear... Heh I guess I need to get used to these 'feelings'
Thing.

"Then come with me" he said and put my hands in a chain I looked at them and back at him.

"What in the world?! Why are you chaining me up" I asked and he grabbed my chained hands.

"Just so you wouldn't do something stupid" he said and the worlds went from blue to black to white then we were in a different place.

We were standing in front of a building that has the words 'LAB' in front of it.

'Oh great he's going to experiment on me isn't he?' I thought and while we walked a gray hallway.

"Alphys,we have a problem" Sans said and a short yellow nerdy dinosaur walked inside the room.

At first she was surprised to see me but then she noticed I wasn't '(y/n)'.

I sighed and felt the loneliness take over.

I'm glad that she had people who still love her for what she did. Even though they're monsters. They don't judge one another so harshly. Except for humans who don't fucking care even if they see a girl getting raped by a complete stranger.

I was in deep thought when I felt something getting placed beside me. I turned and what I saw was a mirror. And on that mirror was (y/n) looking at me. Still chained. She now feels my pain. The mirror reflects the background of where we are so it may look like she's with us. But on her point of view. She just sees us from the shape of the mirror and even if she punches the one she's looking at it will break the mirror.

The only way to get her out of that void is through InSaNiTy. I've had enough InSaNiTy in me... Then an idea sparked.

'The only way to get her out is to. Go. Back. To.
