Chara was lying in a pile of golden flowers. She stood up. These flowers were her Dad's favorite, she remembered. She walked to the next room, where she would meet Flowey.
Chara froze. She was wrong. Something had failed. She didn't RESET right. Sans shouldn't be standing where Flowey should be.
"WELCOME, DIRTY KILLER," said Sans.
"H- hello, Sans. Um, is everything alright?" Chara responded fearfully.
"i can't believe you would butcher your own father and mother. i don't get it. everyone trusted you, but you turned around and killed us. now, it's time for my question..."
"... DO YOU WANT TO HAVE A BAD TIME?" Sans asked.
Chara realized she had made a mistake. She witnessed her own death hundreds of time. She didn't know that Toriel was the same Toriel that had been her mother. She didn't know that Asgore was the same Asgore as her father. Chara felt Sans's karma hurting her already. No, it wasn't Sans doing this. It was her own LOVE and EXP. Chara felt a tear come down her cheek as she felt a bone impale her through the heart.
As her determination brought her back to the bed of flowers, she saw Sans walking into the room. "you didn't attack me," he said, with a curious tone with a hint of concern. He noticed, during their fight, that her soul was black, unless she was attacking. When she attacked, it turned red. Sans was intrigued.
"I know," Chara said with more tears forming. She couldn't believe what she had done. Until she could. Her irises went from their red brown to a complete red for a moment. She gripped her knife more. "But I will fight now," she said. Her voice was almost demonic.
"welp, guess you're ready to do this again," Sans said as he made a Gaster Blaster.
Chara dodged the first shot but was incinerated by the second. When she respawned, she had lost the will to fight again. Her eyes faded back to normal. Sans made a cage of bones around her. He pulled out his cell phone and dialed Alphys.
"hey alphys. yes, i'm fine. no, she's not free. you were right, it's black. the weird part is that it goes away when she attacks. you think you have something? okay. send rg01 to bring it here. alright, directly into her soul. i've got it. bye," Sans said into the phone.
Chara sat up. She felt tears in her eyes. She started sobbing. She was done with this. She picked up her knife. She was about to throw it, thinking about how many lives it had taken. She realized she could fix everything if she had it take one more life. She stopped crying.
Sans heard the noise of a knife hitting flesh. He turned quickly to look at Chara. She had cut her finger a bit. Sans took down the bone cage and ran to her. He grabbed the knife.
"What are you doing! I almost fixed everything!" Chara said, starting to cry again.
"no, that wouldn't have fixed anything! in fact, that only would have made things worse!" Sans yelled, out of anger, fear, sadness, and compassion.
Then, RG01 ran in. He was holding a small suitcase, "Hey, Sentry Sans! Here it is," he said, handing the case to Sans.
Chara stood up, with a wild look in her now red eyes. She ran toward Sans and RG01. RG01 hit her with his sword and Sans stuck a bone through her foot. RG01 was about to hit Chara again when Sans stopped him. He looked into Chara's eyes. Sans noticed they changed color, just like her soul. Right now, they were normal. Her soul was black. She was crying. Sans opened the briefcase.
Inside was a needle, a shot, and a tiny jar of a sickly yellow liquid. Chara's red-brown eyes grew wide and more tears started to fall. Sans put the needle on the shot and filled it with the liquid.
"P- please, don't put that in me!" Chara screamed.
"don't worry, kiddo, it'll help you get better," Sans said.
He brought Chara's soul forward. He stuck the needle in her soul. Chara's face went pale. She started to sob. Sans injected the liquid.
"one. two. three. four. five. six. seven. eight. nine. ten," Sans counted.
Sans pulled then retracted a shadowy, dark goop out of Chara's soul. Chara clenched her chest as Sans put her soul back. Sans removed the bone and turned to RG01. Chara limped to the bed of flowers and laid down.
"hey, rg01, go get toriel. it's her turn," Sans said.
"On it, Sentry Sans!" RG01 said as he ran through the ruins.
Once RG01 was away, Sans turned back to Chara and sat beside her. He said, "hey, kiddo. how're you doing?"
"What did you do to me? Am I going to..." Chara asked.
"do you know about LOVE and EXP? i gave you something alphys made called a COP. it will allow your soul to move back to where it was before you killed. i removed your EXP. unfortunately, your LOVE can't change, though. and no, you won't die," Sans said.
"Sans, thank you. I- I'm..." Chara said.
"you are what?" Sans asked.
"I'm..."
"...Sorry," Chara said.
"you know what, kiddo?" Sans said.
"What? Oh, I know. You can't know if I'm even safe. You don't trust me, and you won't forgive me. I shouldn't have said anything," Chara said.
"no. i forgive you," Sans said.
