Hello everyone!!! My friend @lilleana16 laughed at the part where I put her in. She then told me to call her evil side lillith, so that is what i will call her evil side from now on!! Also, Sans got hurt, but he now has been training to get his health up. He now has 250 health in 1 week. He doesn't want to die which is the reason he is training!! I also tried to prank her by writing down lyrics of the song called stromger than you, but it didn't work. She caught on fast. Now, on with the story!!!!!!!!!!

We all went back home since it was almost 10:00. Sans teleported me to my house since I was tired as heck.

"Goodnight Sans."

"Goodnight kiddo." He then kissed my forehead and then teleported back to his house. I soon fell asleep.

Sans POV

I was worried since Frisk looks like she hasn't gotten any sleep. Maybe she has been getting nightmares again. I don't know why, but I kept getting dreams of something called the genocide run. It was a kid that looked like Frisk and Chara mixed together. They were killing all the monsters where we used to live, the underground. They were so heartless that they even killed Papyrus. They basically made everywhere I go silent. I would always wake up when they killed one of my friends. I was always sweating and I would always cry. I hope she isn't getting the same dreams. If she is, we might have to go to Alphys to ask her since the dreams would be connected. I just teleported back to the house and went on my bed with a sigh. I fell asleep, hoping to actually get some sleep for once.

Frisk's POV

I was having a nightmare again. I was getting sick of these nightmares. It was always of my previous life. Though I don't remember killing everybody. I'm a pacifist. This would be more like Chara. I would always wake up vomiting and crying.  This time, it was me killing Sans, the one I love the most. I kept screaming for me to stop, but my screaming was just turned to inhumane giggles. After what seemed like 2 hours of dying and dodging, I hit Sans. My eyes widened as he fell to the ground." Well, I warned ya kid. I'm gonna go to Grillbys. Hey Papyrus, do you want anything?" I cried as he said that since I "killed" Papyrus. I screamed Sans' name as I saw dust where he was walking.

I then woke up. I live alone now ever since the king and queen dance, which was good since I think I was screaming in my sleep. I got up as fast as I can and then ran to the toilet. I vomited until I felt somebody hold my hair up. I forgot that my sister Chara was living with me. She was also crying. Maybe both of us were having the same nightmares." I, I killed Sa-" She interrupted me." Shh. You didn't kill him. It was me." She then started to tear up. We both started to cry together. When we had calmed down, we started to talk about the nightmares.

"So, I have been getting nightmares ever since the dance." I told her.

"Yeah, me too. It was my old self looking like you killing everybody. The monsters despised me for some reason and treated me like trash. So I killed them all. I realized that they were not the monsters. I was. I wanted to reset, but my body didn't let me. It kept my hands from moving. There was a part of me that had already turned into a demon. I was trying to regain my body again, but I couldn't so I just let the demon kill everybody while I was crying. I was able to regain my body to make a True Reset. So I did. I felt flowers under my feet. I tried to grab one but couldn't. I was a ghost. I then saw you. I helped you not do the genocide route or you will become a demon like me. I also had you fight Asriel( which made me laugh so hard since he finally became the God of Hyperdeath.) so you could do the true pacifist ending. You finally had your good ending which also made me happy to see everybody having a happy life. Then I was able to get a body, but everybody forgot about the underground and who saved them. Only I remembered. I wanted to forget everything about the underground like you guys, but I just couldn't." I started to feel bad for Chara since she had to remember everything. I also was getting flashbacks of all the times in the underground. When all the flashbacks were finished, all I saw was black.

Chara's POV

I saw Frisk sitting still until she fainted. I caught her just in time. I decided that the only other person that would know about timelines is Sans. I called him, but didn't expect him to answer since it was 12:00. I heard him panting hard." Hey Sans. We need you to come to our house. Just so you know, we moved into a new house." I told him." OK, I know. Frisk already told me about her new house."

" Yeah, we need you, and fast. SO HURRY UP!!!"

"OK, jeez kid. If it's a big emergency, I'll come fast." I then saw him in front of me. Me ad Frisk were only wearing our undergarments, but I didn't really care. Sans had a little bit of blush and he turned around." Um, kid. Put some clothes on, as well as Frisk." I smirked." Haven't you already seen Frisk like this though?" He then started to widen his eyesockets." H-how did you know?" Well I heard the door open, so I peeked outside of my room to see you come out and wait outside. You then started to say that you were an idiot for teleporting without telling her. Me and her always wear our undergarments to sleep, so I figured she called you and you just teleported into her room without telling her." He then sighed." Damn are you a smart kid. At least you put some clothes." OK, brother-in-law." He then started to get blue. I walked away to my room. I then heard him yell." We aren't married yet!!" I smirked again even if he couldn't see it." Why did you say yet?" He then kept quiet, knowing that I wouldn't stop. I then came out with my pj's on. 

"So, why did you call me?"

"I thought that you would something about timelines and the genocide run." His eyes then widened.

"Yeah. I have been getting dreams of me in the so called genocide run. It looked like Frisk, but it sounded like you."

"Well, better be surprised to hear the whole story, then faint after getting flashbacks like Frisky did here." I then told him the whole story. At least he didn't faint after me telling him the whole story. Frisk woke up when I had just finished.

Frisk's POV

I woke up. I had gotten some sleep. I realized I was sleeping on Chara's lap. I got up and also saw Sans."Sans? What are you doing here? And Chara, why was I on your lap?" I asked. Chara answered them both since it looked like Sans was having flashbacks." Well, I called Sans over to tell him about the timelines and genocide run. And you fainted after I told you." I then started to feel dizzy. Sans was also back to the real world. He blinked. Then he said that he had to go home. I wondered why. Then I was exhausted. I fell back to sleep and tjis time, with no nightmares.

The next morning....

Me and Chara were getting ready for going back to the hospital to see our siblings. We were gonna take Undyne, Alphys, Papyrus, goat parents and Sans. My parents were glad to see my real mom. They got along very well, especially both of my moms. They both love to cook food, which they would like to cook together one time. Undyne and Alphys were carrying the babies. Undyne got hit in the face by Athena." I like this baby!! She will make a great warrior!!" She said. Alphys was carrying Treasure and they were examining each other." T-This baby's c-changes colors! H-he is a-also examining m-me. I t-think that he w-will be a great s-scientist!" Sans was then carrying Luna. Luna's eye was glowing like Sans. She then got a little gaster blaster. She giggled and turned it into a necklace. It wrapped around Sans neck. Then I saw another one appear and wrap around my neck. They were matching only that Sans was blue and mine was red. Luna also had one that was the color pink. Chrisk was being carried by goat mom and Chrisk had already learnt how to walk. 

We were all having a good time, until I heard a scream. It sounded like it was still in the hospital. I got out to see Chara holding a knife. She was going to stab a nurse. Her hands were shaking and her eyes told me that she doesn't want to do this. Right when she was going to stab the nurse, I dashed in front of her. She stopped right when she was going to stab me." I- I... I'm sorry. I don't know what got into me. I saw blood an-" I stopped her by hugging her. She was shaking in fear."Chara. Shhh. It's OK. I know that you didn't mean to do it. Is the demon still inside you?" I asked." I'm pretty sure it is. I still shake when I see blood." She answered." OK Chara. It's fine. Let's go back to mom's room. I bet they are waiting for us." I smiled and she smiled back. We went back to the room where they were all worried. I told them the fear that Chara has and what had happened right now. They all understood and decided that it would be best to leave so then mom could get some sleep. Luna however, was holding on to Sans while Athena was pulling Undyne's hair. We got to take them home and saw that Treasure was writing math problems and giving them to Alphys to solve. Mom got to keep Chrisk and we took the rest of the babies home. We decided to have a sleepover at my house.

Magical time skip by School

Me and Undyne decided to make food for everybody else while they were talking and catching up with each other. Me and Undyne were talking about our relationships.

"So Undyne, I heard that you and Alphys are dating now."

"Yeah. I also heard that Sans saw you in your underwear."

"Yeah, I called him and he teleported inside of my room without telling me. He is sometimes so dumb and gullible when it comes to friends."

"Well, I live with only Chara now. It's a pretty nice house."

"Yeah, do you have any extra rooms? My house burnt down again and Alphys doesn't have any extra rooms."

"Yeah I have some extra rooms. You could live with us for now. It would be pretty fun to have you over."

"Okay. Thanks punk!! Now let's serve the food. I bet they are hungry as f*ck."

"Undyne!! No swearing in the house!!" We then finished making the food and served everybody their food. The food was pretty good too, and I was full when I finished. We all started to watch a movie. We had also put the babies in the baby room to go to sleep. The only one that wouln't go to sleep is Treasure. He likes to do math problems and he also likes anime. He was watching Attack on Titan with us and I was wondering how he was not getting scared of all the blood. When we finished, we all went to sleep. Our house had enough extra rooms for everyone, except for Sans and Luna. They were both going to sleep in my room until we add another baby room and extra room. Luna fell asleep in her crib while me and Sans fell asleep next to each other. We both fell into a peaceful sleep.
