That was far from the last time it would happen. Throughout the rest of Frisk's journey through the Ruins, Frisk was haunted by things Toriel never said. Or would never say. Requests for death. Release from this world. Frisk would be repeatedly creeped out, or scared by such small incidences. But, no scare had quite the same effect twice. Eventually, Frisk just got used to it, asking Toriel to repeat herself, if something came out incorrectly. Granted, it still gave Frisk the chills, and goosebumps, but... it was never quite so frightening again.

Frisk, often, would ask Toriel to repeat what she'd said, and Toriel happily obliged, assuming the young human was simply hard of hearing, and had anxiety issues.

Eventually, Frisk left the ruins, and continued on with their journey. 10 more times. 21 times. 37 times more. And those thoughts about killing monsters would come back, sure as the light of day. And this time, Frisk tried Papyrus. The monotony of time, and the growing negative feelings towards their trappings, made this easier, but still heavy on the heart. This time, however, Frisk was able to avoid loading. And would continue onward, despite the feeling of that wad in their stomach getting heavier.

And then, on another run, it was Undyne's turn. Undyne's unending hatred for humans made it much easier than killing Papyrus. Even knowing that Undyne could, with potential, become Frisk's closest friend, wasn't enough to force Frisk to load, and undo that murder. But the guilt only got heavier.

Then, Mettaton. Then, Asgore. Heavier, and heavier. But Frisk didn't notice it much anymore. Over time, Frisk grew accustomed to the feeling of a heavy heart, laden with guilt. None of these monsters deaths, however, brought Frisk to a happy ending. Because, without a Boss Monster soul, the human would die upon contact with the barrier, and wake up in that bed of yellow flowers once again. The smell of asters heavy.

It wasn't over. As Frisk progressed forward, the voice whispering at the back of their mind got louder, and louder. Still unintelligible, but very much noticeable now. Each kill brought Frisk less, and less guilt. The guilt was slowly being replaced with... something else. Adrenaline, perhaps. Or Determination. Killing monsters began to become a completely detached action. A mechanism. Testing the depths of terrible things that needed to happen, before a true ending could be achieved.

Frisk finally, after killing all of their other friends once, tried again with their loving mother, Toriel. It still hurt so much, but it wasn't nearly as sickening. Frisk moved on, finding this ending held no release. Then, it became a series of experiments, as Frisk went around, and killed combinations of two monsters each. Then, three. Then, all of the boss monsters. Before long it became clear that the secret didn't lie in killing Papyrus, Toriel, Undyne, Muffet, or Mettaton. Perhaps there were monsters that hid from Frisk. So, Frisk hunted down the farthest reaches of the underground, to find other boss monsters. Glyde. So Sorry.

Eventually, it came down to the minor monsters. Ice Cap. Arron. Shyren. The temmie. Pyrope. On, and on, Frisk went down the tunnel. It wasn't until the 1482nd journey, that Frisk discovered that, they could kill enough monsters in any given area, that no monsters would show up again. More experiments, clearing only one section between boss monsters, then combinations of two, or all. Then all, and only some boss monsters.

What seemed like centuries later, in Frisk's eyes, it finally came down to an actual Genocide. A quest to kill every monster in the Underground. It was at this point, that Frisk had become so emotionally detached in what they were doing, that everything was just coming down to statistics. How quickly were they able to kill certain monsters, making mental note of just how quickly they could kill every monster in an area, making a game of clearing The Ruins, Snowdin, and Waterfall as quickly as possible.

The first road block, was Undyne. More particularly, Undyne the Undying. Frisk counted 72 tries, before finally laying the passionate warrior to waste. They expected a harder fight from Mettaton, and got nothing. And then, it came down to the judgment hall. The fight with Sans. This one took... significantly longer than Undyne. At least 300 tries. Imagine the anger, and embarrassment that Undyne would go through, if she were ever told that Sans killed the human more times than she did?

And that... that was when Frisk could no longer act of their own volition. Not that they think they would have done things differently, at this point. They were dedicated to their course of action. They marched upon Asgore, and killed him swiftly, without mercy, watching his soul shatter. And, lastly, cut Flowey down to nothing. And then, without hesitation, walked into the barrier alone, letting the embrace of death take them.

And then... nothing. No flowers. Frisk didn't wake up.

Frisk... never lost consciousness. Painless descent into a simple darkness, where there were no sounds, beyond the true sound of silence.

Thump-ump. The sound of a distant, but loud heartbeat broke the silence in the darkness, and Frisk looked around this black void for the source. But it sounded like it had come from all directions.
Thump-ump. The heartbeat came again. This time, a pair of glowing red eyes pierced the darkness. Followed by the visage of a human. Approximately the same height, and age as Frisk. They were wearing a green, and yellow sweater.

"Greetings." They said, but their voice never came. Instead, it was more like a whisper at the back of Frisk's mind. The same whispers that had started to gather while the guilt in Frisk's stomach had ruminated at first. Frisk's entire being chilled, from the inside out, at hearing that. Because it was much like hearing something you didn't hear at all. "I am Chara?." They whispered, again.

That name... it felt familiar. And yet, at the same time, it wasn't just one name. It was thousands of names, all whispered at the same time.

"Thank you. Your power awakened me from death. My... "human soul". My "determination". They were not mine, but yours." There was a short pause, but every microsecond of silence felt like an eternity. Time, here, was dilated beyond human perception.
"At first, I was so confused." they started, "Our plan had failed, why was I brought back to life?" Another pause, "You. With your guidance, I realized the purpose of my reincarnation. Power. Together, we eradicated the enemy, and became strong."

This, Chara?., then spoke of some things that Frisk did not exactly understand. Numbers. Letters. Statistics. Like the ones Frisk had started keeping on how quickly they could get from point A to point B, Frisk assumed. This was all so bizarre. This... this was the first human, wasn't it? The one that the monsters of Underground had called... Chara. The human they'd heard Asriel talking to in those home tapes. The one that was long dead.

"There is nothing left for us here. Let us erase this pointless world, and move on to the next."

Erase this world, and... move on to the next? That... it sounded like a familiar action, but at the same time... that sounded completely... wrong. It wasn't the same, not by a long shot. It made Frisk squirm. Except, Frisk couldn't. Frisk, here, did not have a body. A thought began to ring out in Frisk's mind. Echoing over, and over, and over, getting louder, until finally...

"NO!" The word reverberated strongly. With all the will, and determination Frisk could muster.

There was a short pause, again like an eternity passing.

"No...?" The whispers responded. "Hmm... how curious. You must have misunderstood." The figure before Frisk began to slowly melt, their eyes becoming great expanses of black tar, but that devious smile never fading. "SINCE WHEN WERE YOU THE ONE IN CONTROL?"
