A/N this is some of the darkest stuff I had written. When I got done I was mourning for my character. So if you are very emotional I was heed this warning before reading. Frisk is 17 years old in this situation.

She didn't have much strength left. "Frisk come on just reset." She smiled at him and shook her head "I can't for your sake. If I reset so does Chara. No it has to be this way. Take my SOUL and save everyone." He places his hand softly over her chest. It appeared to him like a gift small and fragile but so powerful that it would save open a barrier. He watched as Frisk went into her eternal slumber. "Frisk please....". It was no use. She was gone. He wondered if there would be another reset or a different universe she would be waiting for him. A world where there is no resets no pain no suffering. He brushed her hair out of her face. "We had some good times... didn't we Frisk". He could hear her saying something like "Don't cry Sans as long as there is hope and determination. We can do anything.". 

She made everything into a game, a sweet game, where me and everyone else was allowed to play. "How can I continue without you....?" He whispered holding her hand. It was hard for him to breath. The gaster blaster took a huge chunk of his body apart. 'Damn Chara' he  had to hold Chara she would easily of killed him otherwise. The way she struggled against his powers was crazy and he was already stabbed a few times as well. He status bar was low. Should he just die next to her? He was really tempted too. When Chara kept stabbing his brother he just had to watch in horror. He couldn't move his body it wouldn't allow him too. The shock of seeing his best friend killing his brother was just too much and he didn't know how to react. His status bar showed .3 left on his HP. "Maybe, I will go to Grillby's one last time." He felt his pocket he found his present that Paps left him. He almost forgot his present.  A limited edition of ketchup. Tears fell into his lap. This was his ticket to survive this. ' Was it right for him to live and no one else.'
    

 A memory of Frisk from a previous line came back to him they were at the Echo fields. "Sans, why do you like the stars so much?" Said a much more curious kind Frisk "Because I know that there has to be more than us. That each star has its own universe its own planets and it is own version of humanity. With its own version of me and you and everyone.  That somewhere is a version of me free to do what I want." He could feel himself get depressed and all of a sudden Frisk wrapped her arms around him. "You will get that one day. When it comes embrace it and never look back. We all love you." 

He chugged the special ketchup restoring his health to 1. He kissed her forehead. "I will find you again...I will find our world". He laid her gently down off of himself and slowly got up and walked to the exist. He looked back at the exist he could swear he could see all his friends waving him goodbye. With them Papyrus and Frisk. He turned around and left leaving with the determination of Frisk. "We will do this together...". She was with him all the way to the barrier and as it went down her spirit slipped between his fingers leaving behind a locket. The heart locket she always carried. One side had a picture of him and Papyrus. The other side saying "My world". 

He looked up at the sky. The stars will be out soon. "Hey Frisk .... Is there a version of you missing me because right now this version is missing you. I hope you will wait for me and take of Paps. And don't get him too overworked with puns he doesn't really like them. Pretend to like his spaghetti and don't stay up too late and and... I really love you guys so much...why can't you be here with me now." Tears filled his eyes but he had to be strong. For everyone because now he needed to escort the remaining monsters to the surface and somehow convince the humans to accept them. It would be tough road but he knew that the determination will get him through. He put the locket around his neck and for the first time in a long time he smiled. For he knew that no matter what happens he has and will always be never truly alone.

The end.

A/N: I was bawling writing this last part. So it probably is a little cheesy near the end. For me it had to have a upside or I would have failed a character I truly cherish. ^_^l!l On the upside I will be publishing more stories. https://shippo7842.deviantart.com/  I have several lined up and I just need to finish. So follow me on deviant art or on fanfiction as well as here. Hate/ Love my story leave feedback let me know what parts you liked or hated or whatever. ^_~ Don't worry I won't judge.
