When I felt the knife in my hand move up I quickly turned it and stabbed myself and I got back in control. When Sans panicked I smiled at him. "I'm sorry Sans.....but I have a job to do.....I-I made a promise....." I said. When I saw Gaster's soul I took half of half of my sister's soul before she died and gave Gaster my red one and my sister's blue one and put my sister's and I's soul together. When it was together I felt ears on my head and a tail. I then forgot that my sister was half monster and half human. I then felt magic inside of me. When I looked at my wound it was healed and Gaster was back but is his regular self. When Sans saw his dad he then looked at me with tears in his eyes and Papyrus as well and they both ran to me and hugged me and I hugged back. "Thank you.....Frisk...." Gaster said smiling. When I turned to the portal I saw it closing. "GASTER! SANS! PAPYRUS! THE PORTAL TO THE WAY OUT OF HERE IS CLOSING!" I shouted. When we got to it, the portal already closed. We were now stuck in this world for a while. When I saw Char again I freaked out but realized it was a girl. When I came from behind Sans I smiled. When she fell to the floor I ran to her and I had my hand out. I then said something that my sister would always tell me. "You are filled with DETERMINATION....." I said smiling. When I opened my eyes they were back to blue. When she took my hand I pulled her up. "My name is Frisk. What's your name?" I asked. "My name is Chara...." she said smiling. When I looked at Sans, he saw that I looked worried because mom and dad are probably looking for me. "Don't worry Frisk. We'll see Toriel and Asgore again when we find a way out of here...." he said smiling. When I smiled back. I went to him and grabbed him by the collar of the shirt and lift him up and asked Papyrus to help me. When he picked up Sans, Sans went to sleep and I giggled while smiling softly. When I saw the other Papyrus sleeping I poked him and he opened his eyes and bent down. "What is it?" he asked. "You don't mind us living with you guys for a while do you?" I asked. He then sighed. "Alright....you can live with us.....but....if you hurt blue or Chara I will kill you......." he said. When I nodded my tail started to wag. When I felt someone touch my tail I shrieked. When I turned around I blushed because Sans is the one who did it. "S-Sans........." I said blushing and then my face turned red. "Hm?" he hummed. "I feel weird....." I said blushing even more. When he saw my face he chuckled. When I felt my eyes sting he made a run for it. When I was chasing him I smirked and jumped at him and caught him with the others watching. Papyrus and Gaster were shocked because I never beat Sans and this is the first time I beat Sans and Sans was surprised. When I stood up I took his hand and pulled him up. I then quickly put a woophie cushion in my hand and stuck my hand out. "Lets make a truce...." I said smiling innocently and he knew I was faking it but went along. When we shook hands the woophie cushion made the fart sound and we both started laughing and I fell to the ground and Gaster and Papyrus sighed because they both hated puns and pranks. When we stopped laughing, I stood up and thought of something. "Hey Sans. Knock knock..." I said smiling. "Who's there?" he asked. "Dishes..." I said trying not to laugh. "Dishes who?" he asked holding it in too and so was the other Papyrus. "Dishes a very back joke....!" I said laughing and Sans and the other Papyrus started laughing as well. "FRISK!" Papyrus shouted. When Sans and I saw a pie we smirked. "Frisk, Sans, no....." Papyrus said. "Oh look it's......Pa-pie-rus!" Sans and I said at the same time. "FRISK! SANS!" Papyrus screamed. When he walked off to calm down I heard a grunt and saw that Papyrus' skull was cracked and I panicked. "SANS! GASTER! PAPYRUS' SKULL GOT CRACKED!" I shouted freaking out. When Chara tried to calm me down I felt pain so when I looked in front of me there was a boy verion of me and when I saw blood on his knife I heard Chara scream my name and that caused Papyrus to wake up and when Sans looked at me, I looked down and saw......blood....my....blood. When my eyes went wide I screamed in pain when I was stabbed again. When Sans saw this he summond a gasterblaster but when I fell to the ground, my soul came apart but I heard my sister's voice. "Frisk...you must stay determined...." she said smiling. "But Angel.....I'm....I'm scared....." I said. "Here. Have my powers. You might need them. When your injured I will heal you. And always remember.............You are filled with DETERMINATION....." she said smiling. When my soul came back to get her I stood up and had claws with my eyes glowing blue, orange, and red. When I charged at him he dodged. "FROST! STOP! YOU CAN'T KEEP KILLING INNOCENT PEOPLE OR MONSTERS!" Chara shouted. "Listen Frost.....I don't know who the he'll you are but....you. Better. Not. Mess. With. The. Wrong. People...." I said. When I looked at Chara for permission to kill him she nodded and covered Blue's eyes. When I killed him I was injured so Angel healed me.
When I fell on my knees I felt weak and then Sans ran over and picked me up and I was then knock out.
