Chara scowled. They had gotten used to the continuous flow that all the timelines lead to. All the lines that were spoken by each of the monsters, their quirks, the looks on their faces when a betrayal kill happens right after a monster SPARES them. The times they let Frisk be in control to lead to a "Happy End" only for Chara to swoop in and destroy it thanks to their first Genocide Run allowing Chara free access to the human's body anytime they wished.

Ah yes, the Genocide Routes. Remembering the feeling of dust covering their (or rather Frisk's) hands made an evil smile begin to form on their face. Those runs were always Chara's favorite, and the ones where what remained of Frisk would scream in pain from. Not that there was much left of the fallen human now after Chara's been in control for the past several resets.

Chara's fingers folded in on themselves a little, as if they were holding a large kitchen knife instead of thin air as they thought about their last run. Nothing really changed this time around… except for when they reached Sans. The skeleton seemed to have been a little… off to say the least. No, no that wasn't quite right. If the child thought about it hard enough they did feel something was different BEFORE their tangle with Sans.

There had been something wrong from the moment they killed their once adopted mother Toriel during their last run. Before turning into dust and saying the usual lines of "Now I know what I was trying to protect…" the child had actually noticed the boss monster's eyes seemed to catch notice of something behind them before fading off into dust.

The same thing happened when they killed Papyrus. The skeleton seemed to notice something that the child didn't in his final moments and looked like he was almost being… comforted? Chara had originally just brushed off those thoughts when they stabbed the decapitated skull between his eye sockets.

Now that they really thought about it, they did have the feeling of being watched since their first kill during that run. It just didn't come into complete play until they killed Sans. They were used to him walking off and asking his dead brother if he wanted anything… the difference this time however came from the fact he didn't even say he was going to Grillby's before questioning it and he seemed like he was actually looking at his brother when he said it as well. They decided foolishly to not look back and just continued forward to kill the king.

It turned out to be a huge mistake on their part for as soon as Asr- Flowey, was killed they were ready for the final stretch that would kill off the very small portion left of the child once known as Frisk. However before leaving the underground one final time… an unknown Skeletal monster made itself known to them and one hit killed them, not even giving them a chance to dodge the attack.

What was worst from that encounter was that the skeleton seemed to be able to… delete their saves and force a hard reset on them. Even worst then that was the fact Frisk seemed to gain a small amount of strength back from the nearly ant sized influence they had left before. Whatever the unknown skeleton did, it aggravated Chara to no end.

"If I even see that skeleton again…" Chara growled to themselves as they forced Frisk's body to stand up from the bed of golden flowers that held beneath the true remains of their original body.

...

Flowey flinched at seeing Chara come walking in once again. Underneath the dirt where his roots were he was shaking in fear.

"H-Howdy Chara!" Flowey managed to speak, fear making itself known in his false cheery voice. Normally he wouldn't be able to remember the death he suffered at the hands of his once best friend after the genocide runs but this time…. he remembered it pretty clear and was terrified to be on the receiving end of that brutality once again. A hollow vessel he maybe… but there was still just enough left of his original soul as Asriel left in him to remind him how almost all his emotions, aside from love, worked.

"Flowey…" Chara snarled, the normal coloration of Frisks eyes having started to take on a slightly more red tint to them thanks to Chara's influence. They did take notice that Flowey seemed to remember their last "playthrough" and that was just another thing to add on the suddenly growing list of things that generally ticked them off. So far the top two positions on that list were the mystery skeleton…. and buttercups to be honest.

"Y-You're…. going to go kill everyone again…. Aren'tcha?" Flowey asked, sinking himself a little lower into the ground and avoiding eye contact.

"Of course I am. After all it's as you've said countless times now… It's Kill or be Killed," Chara smirked a little. Flowey continued to look down to the ground to avoid having to see the possessed child's face.

"R-Right… Kill or be Killed… I'll just… I'll just leave you to that then," Flowey laughed nervously before sinking into the ground. A plan to stop what was once his… no Asriel's best friend and adopted sibling, began forming in his mind. Even though he hated the idea of it…. but he may just need some help in order to succeed.

Chara frowned at the sudden departure of the yellow flower but decided it wasn't worth their time to be bothered by it. After all they had a "Game" to get through.

~Post-Reset~

What was left of Frisk inside the soul Chara controlled was curled up into a fetal position. They could barely hold themselves together anymore thanks to all the damage done to their very being. If someone could see them now, they would see a young child who almost looked like they were…. glitched out and very broken looking so to speak.

They just wanted everything back to normal… they wanted to go back to their true ending. The happy one they worked so hard to get. The one where they had friends. They cried into their broken up knees. They missed their home with Toriel, cooking with Undyne, doing puzzles with Papyrus, stargazing with Sans, watching anime with Alphys, listening to mixtapes with Napstablook, posing with Mettaton and having tea with Asgore…. they missed their friends more then anything.

It was not meant to be however…. barely three months after making it to the surface was when the real trouble happened. The cause of them accepting Chara's influence to begin with.

I… I wish I could just go back and stop myself from doing that… Frisk thought, new waves of tears peeking out from the corners of their closed eyes as they began to feel themselves fade away just a little bit more as Chara killed Asgore once again. Once that was finished Frisk knew that soon after the hellspawn would make them kill Flowey and leave the underground once again. Frisk just knew…. once Chara made them cross the barrier one last time that Frisk would cease to exist.

Eighty nine steps…. then I'm gone for good… Frisk thought having memorized the amount of steps it took for them to reach the barrier from their current position. They were surprised however… when after only one step forward Chara forced their body to jump back. Taking quick notice they found a strange looking bone magic blocking their way. They had no idea what was being said or what was going on other than an unknown skeletal monster… was stopping them. For the first time in a long while… Frisk felt hope start to form within their fading existence.

Even though their soul shattered and was forced through another reset, they felt hope. Hope that someone would be able to stop them. Hope that someone would end all the resets once and for all. Hope that… that they can get their true Happy ending back. Biting their lower lip they forced themselves to stand with what was left of them in their own stolen soul. They felt some parts of them that had began to fade return as well as some of their own influence.

Feeling their strength return to them and the prospect of being able to be with their friends again and away from Chara's control, no matter how many times it had to happen… it filled them with DETERMINATION.

...

Sans woke up in his room with a sigh. The white pinpricks in his eyes looking straight at his wall with half opened eye sockets.

"paps will be coming in soon…." the skeleton muttered quietly to himself, having relived this day far too many times to his liking. He curled up unto his sheets more and closed his eyes from the mulberry colored walls, waiting for his brother to come in and wake him up for their sentry jobs. With his eyes closed he could hear the distant sound of clanks and bangs from some pots and pans in the kitchen. The same as every reset morning. What was different though was that he heard his door open as the familiar sounds of the kitchen continued to ring out.

what the? Sans questioned, confusion crossing his mind as a situation like this has never happened before.

There was no sound of footfalls on the off white carpeted floors but Sans could tell someone was making their way to his side. Magic flared up in his left eye socket, giving off a teal glow within his bunched up sheet bundle as a just in case whoever it was would try something… unsavory. The person was by his bedside at this point, no sounds were coming from there, almost like there wasn't anyone there to begin with. If Sans was any less aware of the timelines he would have brushed the feeling off as nothing but paranoia… but now the paranoia was well accepted.

What he wasn't expecting was a gentle touch on where his shoulder was, before the nudging began.

"Sans, time to wake up," an unfamiliar…. yet for some strange reason completely familiar voice spoke as they attempted to wake the short skeleton up. The glow from his eye died down into their usual pin pricks and he pulled himself out from his little cocoon to see who had "woke" him up.

The person was an unfamiliar skeleton (But he wasn't) who had a head shape somewhat similar to Papyrus's but more rounded. A pair of glasses was sitting on his skull in front of his to dark sockets, one looking more half opened then the other, with white pinpricks in their depths for where the eyes would naturally be. What really confused Sans was the fact that he didn't feel threatened by this skeleton and almost felt…. completely comfortable and natural to be around him.

"Papyrus said to wake you up early today," the tall skeleton smiled calmly, his accent clear in each word he spoke confused Sans even more as he had never heard one like it (No… no that wasn't right he had heard it multiple times in his life.)

"who… who are you?" Sans asked, his skull hurting as it seemed like something was attempting to block information from him that almost felt like it should have been common knowledge by this point in time. Instead of looking confused by this the other skeleton simply gave off a slight smirk (or as close to a smirk as one could get with a skull face.)

"Want to take a wild guess?"

"..." Sans was quiet. His mind was trying to rake in the information that he felt that he knew deep down in his bones (hehe) the answer to… however nothing came. The taller skeleton simply sighed after a while.

"Should have figured. You are one of few who know of the resets after all," those few words surprised Sans. Not once has he ever told anyone he knew about the resets… except perhaps the kid but that was more through hinting.

"how did you know that?" A knowing smirk crossed the other skeleton's face as he stood up, letting Sans see his long black coat that looked like it faded around the edges only to reform softly, over a white turtleneck sweater and his bony hands having large holes straight through his palms.

"You we're the closest to me and the machine when it… glitched so to speak, and caused me to be erased from existence. The backlash resulted in knowledge of the resets," he explained, causing faint memories to form in Sans's head. One memory stuck out from the multiple fragments from the scene that was told, one where a younger him was screaming out for the other skeleton, his hand stretched out as the older one was ripped apart by the malfunctioning contraption.

"dad…."

That single word made a smile cross the older skeleton's features as the younger one had tears starting to form in the corners of his eye sockets. The father, one W.D. Gaster, held his oldest son close to him as the blue tinted tears fell from Sans's face and getting into his coat. A soft smile soon turned into one of determination and controlled anger as Gaster thought about events to come.

If that hellspawn even lays a finger on my sons. There will be no Mercy option so long as I have a say in it.
