Chapter One

Curiosity

Sans was sitting in Grillby's, as he usually did. He was once again drinking his problems away, because he didn't know what else to do about it. He was so tired of these resets, they felt endless to him; like they would go on forever and there was nothing he could ever do about it. At one point, he stopped caring, and let time go on without him. He became lazy, and a nonfactor in most people's lives. He would just sit there, eating, drinking, and sleeping. A nonstop cycle of laziness became his life, and he hated every second of it. He stepped outside, knowing that Frisk would show up soon. But this time, he would do… something new.

Sans walked to the forest. If his timing was right, Frisk was going to be there soon. But this time he decided he'd try to do… something different. He decided that he should just kill Frisk right then and there. It would be something different, something he's never done before. But that's what Sans needed right now. He needed something different, something unique, just anything new in general would be welcome. He was sick and tired of the same routine over and over again.

Frisk started their walk through the forest, and passed the branch that Sans would usually break. But this time, instead of breaking it, Sans quickly threw the branch at Frisk and hid before he was spotted. The branch hit Frisk straight in the back, knocking them to the ground. Frisk got up and started to walk towards the gate, but was walking very slowly now. This was something entirely new to them, and new to Sans too. As Frisk finally approached the gate, they listened behind them and heard Sans's footsteps. This was the first thing that was normal for the timeline since they reached the forest, so it brought some relief to them. However, this relief quickly disappeared when Frisk's soul suddenly turned blue and they were smashed against the ground. Suddenly, Sans launched blue bones from the ground through Frisk's body. It wouldn't hurt Frisk, as long as they didn't move an inch.

"hey, kid, don't you remember what i said?" Sans walked towards Frisk very slowly. Frisk couldn't turn around and see Sans, but Frisk was scared for their life. This had never happened before. This was new for both of them. "if we're really friends…" Sans walked closer and closer, his left eye now glowing blue and his right eye going black. "you won't come back." Bones slowly started to rise out of the snow under them. Frisk couldn't move, otherwise they'd have been killed by the blue bones. But if they didn't move, they'd die to the bones that were rising. Impatient, Sans summoned one of his Gaster Blasters and hovered it over Frisk. "this is why i never make promises." Sans fired his blaster, killing Frisk almost instantly. Frisk had a lot of LV, meaning this was going to be a Genocide route. That meant that Sans had zero remorse for killing Frisk. Sans started to walk away, when suddenly he heard a voice that scared him to his very core. He heard the last voice he wanted to hear at that moment.

"BROTHER, WHY DID YOU DO THAT?" Papyrus. Of course Papyrus would show up at that very moment…

"oh, uh… d-don't worry about it, bro. it's nothing you should be concerned about, trust me." Papyrus walked closer to Sans and put a hand on his shoulder. Papyrus was always good at seeing through him.

"YOUR EYE IS GLOWING, SANS. DID… DID THEY DO THAT TO YOU?" Sans didn't even realize his eye was still glowing. He turned away from his brother and hid his eyes from him. What was he supposed to say? That he just killed a child? How could he ever explain the resets? He could never explain that, Papyrus would never believe that. Papyrus would just think that he's drinking again. He would be right, but that isn't the point.

"just… leave me alone for a while, paps. i'm sorry, bro, but i need some space for a bit." And with that, he was gone. Sans ran into the forest, and once he was out of Papyrus's sight, he teleported away to Waterfall. He sat on the bench, in the secret room. It wasn't very secret, but most people just walked right by it, so Sans could go here when he needed space. And if he had ever needed space in his life, it was right now. How could he ever explain what he did to Papyrus? He knew Papyrus wouldn't understand it at all. Papyrus would just give him a speech about how he believes that there is good in everyone, and that nobody is truly evil. In most cases, Sans would agree to this completely, but Frisk was a special case. Frisk had killed everyone in the underground, over and over and over. For no reason other than because they find it fun. Frisk, when they wanted to be, was pure evil. But Sans could never explain to Papyrus that Frisk is a genocidal maniac in other timelines and that he was the only one who could ever remember that Frisk reset the timeline with their special power. All of this was really starting to make Sans's head hurt. He just needed some time away from everyone. He needed time to think, to think about what he's done, and about what he'll do next. This timeline was already so different. Ever since Sans left Grillby's and made it to the forest, everything had been different. This was really his change at seeing something new. This was his chance to finally satisfy his need for change. Maybe there would be some consequences for his actions, but he thought it was worth it. After all, the timeline eventually would just reset, and then everyone would forget about all of this. But for now, he was in a new timeline, and he would treat it a new way.

Sans decided it'd be best to sleep on the bench tonight. He was in no rush to get home, not before he had an explanation to give Papyrus. So until then, he'd stay in Waterfall.

Thanks for reading the first chapter of this! Any feedback would be appreciated, I'd like to write more often. I plan on releasing as often as I can, but I can't make any promises for daily releases. I will try though.
