-----Judgement Hall-----

Before Frisk went on her genocide run you and Sans were arguing. He knew what was happening and was going to Judgement Hall. You were trying to stop him from going and saying it's not Frisk's fault and that something is wrong. That thing isn't Frisk. He wouldn't listen to you no matter how hard you argued over the matter. 

"Sans it's not her fault there's something wrong. She isn't herself. Besides she's a little kid why would a kid want to kill monsters? We need to help her." Sans growls, "Oh and you know so much about her. Tell me, what is wrong with her? Nothing! She's just a kid who deserves to burn in hell. You need to get it through that thick skull of yours that she never cared for us (Y/n)." You tear up but don't give up. 

"She is only a kid Sans. You need to get it through that thick skull of yours that she needs help. If you're not going to help her then I will. She needs our help and I'm not going to leave her. She's like a daughter to me and I'm going to help that kid whether you like it or not." His eye begins to glow as his anger gets the best of him. "Fine go help that goddamn kid. Go get yourself killed for all I care. Cause I never cared about you 'babe'. I didn't even love you." You're frozen in place as you were about to open the door. 

You finally let the tears fall.

You turn towards Sans with the coldest glare you could give. You stalk up to him and slap him. He brings his hand up to his face holding the place where you hit him. 

You've never laid your hands on him or anyone. He looked surprised and like he was now regretting everything he said. 

You walk out of the house looking for Frisk. Tears stained your face as you walk around Snowdin. 

You see Frisk up ahead and you suddenly hear a crunch. You call out to Frisk to see she's standing over dust, Papyrus dust. You let your guard down and talk to her. "Frisk, honey. I'm here to help. I'm here for you and I'm not going to leave you. Please stop this and let's start over. You can fix this, honey. I believe in you." Tears were running down her face as she stood there. You looked into her red eyes seeing the demon who took over your 'daughter'. She runs up to you and hugs you. 

"I'm sorry. I'm so sorry." You smile hugging her reassuring her she's safe in your arms. 

You suddenly feel pain in your stomach. You let go of her and look at your now bleeding stomach. You look up at her and smile. "I know this isn't your fault. Please keep fighting and don't give up. I... believe... in you... Honey..." You fall to your side and watch as she walks up to you and pulls the knife out. You hold your stomach even though you know it's no use. 

You smile up at her as she looks down at you with a strange face. One side is her blue eye and tears are running down her face as she frowns. The other side holds her captor's red-eye and they were grinning like a maniac like they enjoyed your suffering. You watch as she walks away knife in hand covered in your blood and monster's dust. Your vision begins to blur as she's out of view. You look up at the snow falling somehow. 

You are about to close your eyes when you see Sans kneeling at your side. "Funny... How you're... Here and... Yet you... Said you... Didn't care... Funny joke,... Sans." You close your eyes and never open them again as Sans watches your breathing come to a stop and the final teardrops out your eye. He gets up and growls as he teleports to Judgement Hall and waits for Frisk.

After endless battles he finally got her to stop continuing. 

He walks up to her still body and takes the bag. He looks inside to see a book and a knife. It was still covered in your blood. He drops the knife and uses a blaster to disintegrate the thing. He doesn't need to be reminded of how this was his fault that he got her killed.
