And so as the last bit of dust that was once Sans was about to get engulfed and devoured completely by his own attack, it suddenly disappeared into code. And now with the RESET button destroyed, The Underground in this Genocide Timeline, would forever be empty and hollow. With the last sign of monsters ever existing, was the 'death' of the last one. Or so most would think. After Sans and what remained of him disappeared into code. He would soon reform in a completely dark almost limbo-like world. The only thing that could be seen other than the darkness were strange, glitching, and glowing clocks. And there Sans would wake up, gasping for air as if he had almost drowned, but he soon realized that there was no air at all, in fact. He didn't even need to breath, "What the...? What is this place?" Sans asked himself as he got up, when he looked at his own body. He was completely white and he seemed to be glowing as well, he was quite confused by this, he then looked at the many glowing clocks that were everywhere. Each clock had its own color, some were purple, red, yellow, and indigo. But all of them seemed to be slowly dying out in color, odd. Sans, in curiosity went up to one of the glowing clocks, Sans then reluctantly but curiously touched one of the clocks, and the millisecond he did. Everything flowed and rushed into his mind, he saw visions, but not just any visions. Visions of his... home?

He saw himself, Papyrus. Everyone else, but there was something dangerously wrong, everyone suddenly started dying, he saw how they died at the hands of a small human with a knife, Sans immediately know who this was. The visions suddenly ended, Sans was left quite shocked, suddenly. He felt a sudden urge to search the other clocks. It looked like he wanted an answer, he went to a red glowing clock that was also dimly lit like the first one. He touched the clock and saw visions, it was the same thing. Everyone was dying, and at the hands of a small human, this time the human was wielding a knife that was glowing an odd red color. The visions then ended once again. "The ones that have barely any light... their focus is genocide. Their... timelines?" Sans said as he came to this realization, "There has to be one that's peaceful..." Sans said as he turned around and immediately tried to search for a clock that actually had some reasonable amount of glow and light to it. Again and again he just couldn't find one, "Come on, dang it the more time i waste the more likely a pacifist timeline will turn into a genocide one!" Sans said to himself, well. No time has been wasted technically, he WAS in a place between timelines after all. No time here!

Eventually, throughout all that trial and error, he finally found a clock that was glowing a bright light, far more brighter than the others. Without wasting a second he immediately went to go touch it. But it only gave him visions, he saw everyone. But this time, the only one that was dead was a monster, Sans didn't seem to know them, however he had second thoughts on who they were. Cause it felt like it was someone important... No matter, the main focus here for Sans was to save this pacifist timeline. Touching the clocking only gave him visions, and so with a deep breath he decided to fully dive into the clock. And when he did, oh boy he was in for a trip. Once he got inside he was in some kind of 4-dimensional wormhole, every possible light in existence was basically flashing on Sans, which kind of ruined his vision throughout all that. However, eventually. He teleported out of that wormhole, and when he opened his eyes... He was in Snowdin again, he was at the bridge he and the human first met. "Huh... well, that was quite epileptic." Sans said as they wiped away a drop of sweat, however when he looked at his hand. He was glowing slightly blue now... Everything just keeps getting weirder and weirder for Sans. "Now i'm blue... well, a fair sacrifice i guess. And why do i feel more weaker but also stronger? is this some physical thing and i just got stronger with magic? hell if i know." Sans thought to himself.

"Anyways now for the real sacrifice... i gotta stop that human in this timeline. And maybe others too." Sans said in a serious tone, yet he still kept on that smile. Which was no longer of happiness, but of sworn justice. Sans knew this would be a tough task, since he needed to actually find the human first. But no task is impossible. He didn't want to rile up too much attention on himself so he decided to stay hidden and watch in the shadows. But no one was at where he was currently so he was free to move around for now, once he crossed the small bridge he saw that same conveniently sized lamp, just like the old days I guess. "I don't think I could beat them all by myself, might need some help but I don't think they'd believe some random skeleton who claims to be a time traveler... Oh well, then again..." Sans thought to himself as he continued to walk through Snowdin, it was quite empty, which lead Sans to believe the human already killed the monsters in this part of Snowdin, of course he was disappointed. So far he had crossed bridges, completed puzzles... The puzzles are gonna leave a mark, not a bad one. And yet he still hasn't found the human yet, "This means their at the town... Well I need to hurry up then." Sans thought to himself as he hurriedly went to the Snowdin Town and eventually he made it there. He was relieved to see everyone there still alive and healthy. But he couldn't watch for too long, so he hid in the trees while also trying to find the human.

"They shouldn't have progressed so far, i only saw a couple monsters die and it was before they reached the town... Their still wandering around here somewhere, i just know it." Sans thought to himself as he hurriedly but carefully searched for the human. Sans would spend the next 20 minutes searching and searching while in the shadows, eventually he decided to go to the Waterfall entrance. And when he did, it seemed like he was too late. There he saw the human, covered in dust. In front of a red scarf, that once belonged to Papyrus. As Sans witnessed this, he felt his sins crawling all over his back once more. But he had to stay strong, he didn't know if others could pull of what he did and travel through timelines. He might've been the only one who could do this, and the only one who could save these timelines from the humans that reside within them. Sans lifted his right arm about to blast the human, but he decided not to attack them now. "This isn't the right time, they'll just keep reviving and eventually the people over there will hear all the commotion..." Sans stated.

"They treat these worlds like a game..."

"Then i'll be the secret unbeatable boss at the end of their journey."

"And maybe..."

"Just maybe..."

"I could get help from HIM too."
