Chapter 4: GENOCIDE

"SINCE WHEN WERE THE ONE IN CONTROL?!"

- Chara saying to Frisk

Intro
"GENOCIDE" is the 4th chapter of Rosefell AU book 1 series. The Judgment Hall, every human needs to pass through it before meeting the Monsters and the ghosts present inside the Underworld. A battle between Frisk brokes out with Sans and Rose in the Judgment Hall, where Chara initializes her plan with the assistance and help of Gaster.

Synopsis
Rose and Sans meet Frisk at the Judgment Hall, Sans awaiting Frisk who has bloodstains on her clothes and is holding a bloodstained real knife, the strongest weapon in the Underground. Rose, in an indescribable manner, questions Frisk many times to which they don't reply like they always have done throughout each timeline, aside from when they kill someone. Sans, with a cold expression, asks Frisk if even the worst person can change, to which they don't reply once more. He then says his signature line, "DO YOU WANNA HAVE A BAD TIME?", which prompts the start of the battle. The battle ends with Frisk ultimately killing Sans first, then kills Rose by stabbing her in the back (deep enough to reach her soul, ultimately shattering it). Frisk then proceeds to kill Asgore and Flowey, then forced to erase the timeline because of Chara.
