After leaving the ruins Chara went through Snowdin woods killing everything. Then, at one point they hid in the woods for a few minutes as Sans walked past. I sighed and hung my head.

"Just a little bit longer..." I whispered. Chara was distracted and didn't hear me, thankfully. When Sans went past they left their hiding place and started running to Snowdin town. When they got there they killed the few monsters left and stole some food from the shop.

"Oh (Y/N) lighten up. It's just a game." Chara said as they walked past Grillbys.

"It's not just a game anymore. Besides, you're in the game, you know that right. You are just coding. Hell, I am too. Maybe that's all anyone has ever been. But that doesn't mean you can just go around killing everyone!" I shouted, my emotions finally getting the best of me.

"You do realize that you have killed everyone because it was 'just a game', right? You went through sparing everyone and befriending everyone. Then you kill them all. You're even worse than me." They said with a laugh at the end. I clenched my nonexistent fists and looked away. There was no excuse for what I did.

Chara continued on until a fog started to appear and thicken until it became to thick to see.

"HUMAN? IS THAT YOU? ARE YOU ALRIGHT?" Papyrus asked worriedly as Chara walked towards him menacingly.

"Of course it would happen this way. It always does." I murmured and walked up to Papyrus. I hugged him even though I ended up phasing right through him. I held onto him anyway. I was guilty, because I let this happen. This was all my fault.

"H-HUMAN?" Papyrus asked nervously as Chara got even closer.

"I'm so sorry." I whispered as I heard the slash of Chara's knife. I felt Papyrus' body crumble to dust and heard his head fall to the ground. I looked down at him sadly.

"Well, I wasn't expecting this..." He said, unusually quiet before he turned to dust.

"Papyrus?!" I heard a small voice ask, panicked and in shock. I turned to see Frisk standing there. Chara didn't even look back. They kept walking. I was forced to follow. I didn't want to see that anyway.

*~*

Chara was relentless. They killed everything they encountered and then hunted down the rest of the monsters in that area. I felt sick knowing that that had been me once. Well, technically it had been Frisk, but I was controlling them. No matter what they said about simply "asking me for advice," I seriously doubted that they would kill everyone, even if I told them to. I think Frisk just didn't want me to feel guilty.

Eventually Chara made their way to the core. Then when the core was empty of any monsters they made their way through the castle. Papyrus, Undyne, Mettaton, even Alphys were all gone. Chara had managed to kill them all. As they got closer to the final corridor, the judgment hall, Chara started humming a familiar song. It took me a few seconds to realize that it was Megalovania. I started to sing a song I learned from my world to drown out Chara.

"I didn't know what I got into. Somehow I can't go back even if I really wanted to so what more can I do? Here in the end it's just me and you..." I kept singing as loud as I could as Chara walked into the judgement hall. Chara threw me a glare, and I felt a small satisfaction in knowing that I had annoyed them a little bit, at least. I watched as they saved and continued on to meet Sans. Their smile grew as Sans came into sight. He was wearing Papyrus' scarf and had a large grin on his face, but it wasn't his usual grin. It was more creepy. In fact, it almost mirrored Chara's.

"Hiya Sans.~" Chara greeted and he just sighed.

"Let's just get to the point." He said and the battle started. I heard some footsteps and found Frisk running to a safer spot of to the side, which was actually right next to where I stood in my ghost-like form. I felt guilt well up inside of me when I saw the fear on their face.
