The keyboard in front of you was unsettling.

You had managed to summon it, as per Chara's instructions, but it just looked so…wrong. First of all, it lacked any color you had seen in it the first time you brought it forward. It glowed dimly, but was ice cold in your grip. The gray feeling made your chest hurt. The keyboard showed what you had become without your soul: a lifeless machine that was meant to control.

You looked at the keyboard a while longer, when the screen glowed and loaded Undertale. The game was a lot brighter than the pathetic, cold keyboard in your hands. It was so bright and happy in comparison, and you just entered the title screen. Pressing Z on the keyboard activated a SAVE file.

FloweyLV?999:999

Real World

Continue ….

Chara held their end of the bargain and found a vessel determined enough for you to control. Though you still had your doubts. Flowey wasn't the most trusted monster around, and convincing Sans was going to be a near impossible challenge. But you NEEDED your Soul.

You hated feeling nothing. You hated the cold pain in your chest reminding you something was warm there. Now it was taken from you, by someone you trusted. And he stabbed you in the back when you needed him most. Now he had your soul, your emotions, your ability to love, and you wanted to show him so badly how much of a real monster you could be, but there would be no point. The only thing you had was your control, and even that was slipping, and that damn plush keeps smiling at you.

You promptly tore the toy's arm off in frustration, pretending Sans had felt it. You needed the stupid skeleton alive to get your soul back, so the plush would do for your revenge acts for now. Because that's how revenge worked, didn't it? Every time someone wanted revenge, it would be carried out and hurt another person who would want their revenge in an endless cycle of stupid hatred. You hated Sans at this point, glowering at your keyboard, moving Flowey through your world in search of the idiot who took your soul. Great, now your thoughts are starting to sound like Flowey.

By now, the toy was a mess of stuffing on the floor. You had made the thing yourself, and it had taken a lot of time, but now you had destroyed what you so deeply cared about when you could care, the last of your humanity stripped away, and it was his fault, his stupid fault you had torn your work to shreds and you took extra "joy" in tearing is smile to nothing. You pretended the stuffing on the ground was the bastard's dust blowing in the non-existent breeze. If only Sans could know your dark hatred toward him right now. Needless to say, he was no longer your favorite.

…

Sans took in the stars on the surface of this world. He had recently finished off the anomaly and, per Gaster's orders, had taken their rainbow Soul as his own. It was a shame, too. He really liked that kid, but, he knew his job. He couldn't get attached to the anomaly, but he had to get them to fall into the trap. Gaster had commanded it, and it was a plan they had decided on a long time ago. Ever since the appearance of the grey door in waterfall, beside his sentry post. He had met his long lost friend and mentor after so many long years, and Sans trusted Gaster with his life.

The plan was simple. End the world of the anomalies and make sure nothing could reset again. As time progressed, the plan grew more and more dangerous, and monsters around more and more suspicious, especially after the Anti-Reseter was finished (great name, right?) and monsters learned the truth. They needed a false hope so they could get off his and Gaster's backs. So, Sans took a recently trapped anomaly from the void using his machine and brought it to his world, so the monsters could cling to that instead of nose around what he was doing. He just wasn't expecting someone as nice and fun as you.

The way you talked, to how you knew some of the best puns, to just how much you cared for the world despite previous timelines, it had given Sans second thoughts about the plan. If there was one trait in the wonky, multi-trait soul he now had, it was Kindness. You really only wanted to make up for your shortcomings and actually get to know the people who you had control over, and now Sans had taken it from you. He couldn't help imagining how betrayed you would feel if you were still alive. But, you were in the way, and Sans could not bear another reset.

A sudden wave of anger, sadness and betrayal flowed from Sans' chest. He definitely wasn't feeling those before, and it had come out of nowhere. Sans suddenly felt a lot more like trash than he should, and felt the sudden urge to tear plush toys in his image apart by the seams. He looked himself over in the mirror and felt his own grin was mocking him. Was this…what you were feeling? Sans had utterly crushed who you were and he could feel your fury within him. He wasn't expecting to feel your emotions, and he definitely didn't want to feel how broken you were, he was broken enough as is.

More walking around was in order. Gaster was still gathering determination from the nearby anomalies, so Sans didn't have to worry about being spotted. Curious, and with spare time, he took a peak at his new Soul. A small rainbow heart was encased inside his inverted white one, trapped, with no escape. And he couldn't shake the feeling that the Soul should not be his, ever. It was someone else's being he had taken away, after all. But, he had to do it. For his trusted mentor.

…

Flowey was stuck in the grasp of a Gaster follower, with nowhere to go. It and it's collogues had everyone from the mission locked up, and he had recently watched that Smiley Trashbag kill you in cold blood. The one person who truly understood Flowey was dead and the trash had their soul. Reality was screwed. Suddenly, a red light had glowed from nowhere and Flowey found the ability to Save. But, there was no resetting. Darn it. Flowey was compelled to leave the flower pot, and he used his pellets to do so, killing the follower, escaping with Undyne and Alphys, who were horrified by Flowey's actions. He just shrugged and told the duo to follow.

…

The battle ended with dust. You left the soulless marker off the Fight button and sighed with satisfaction. If you were going to get everything to reset via Sans, or reality crashed, who matters at that point. It was a lose-lose situation for all involved anyway. Besides, because of your extensive knowledge, you always knew one thing for sure.

Genocide was always the faster run.
