Hey, all! here's what you've been waiting for... Frisk's side of the story...

Frisk hadn't endured so much psychological torture in their life.

Not even their life before this… with their abusive family, friends who longed for them to disappear, could ever, ever compare to this…

They had been such an idiot… they had no idea what they were getting into when that seemingly innocent voice asked them to try out a RESET. They had pressed down upon the option all too quickly, fearing that if they didn't stick with this world, that the life they had tried to jump to their death for would become real once more.

Now? They couldn't go back. Even if they tried, and even if they wanted to. Chara, as they learned to voice to be, had taken full control. Their determination was downright dangerous, and not even Frisk's unrelenting will to live among their friends again was enough to save them.

They hadn't realized their mistake until it was all too late.

"NO!" they had screamed, struggling to get control as Chara unsheathed their knife, approaching a scared vegetoid slowly. "STOP IT! STOP!" they begged, tears in their eyes as a wave of blackness overcame them, and they were shot back into check.

They had struggled and cried, knowing that this was it. They had made the worst choice they could have ever made. Their curiosity and selfish desires were now to be responsible for the wiping out of the underground. Watching strange monsters they had never met, get cut down? It tore them apart.

What they weren't ready for however, was when each one of their friends had come next.

The icing on the cake was the judgment hall, when they realized that Sans had remembered everything, and was the one who had to take the brunt of the attacks, and be responsible for saving Asgore, and their future. Chara had laughed, called him a fool, and sometimes, won. Sometimes, they lost.

Frisk had noticed that no matter what, they always RESET. They went through the world again, and again, and again, and soon, Frisk had no more tears to spare. They remained in the blackness, giving up fighting back a long time ago, and sitting, sick with guilt. This was all their fault.

They had taken their friends happiness away. They had ruined lives, and ruined them again. They had reduced Sans to a shell of who he once was. Sins on their back wasn't even the name for it at this point. It was more like a weight twice the size of them, holding down their heart, and reminding them every few seconds how much of a dirty monster they were.

The final battle, where Sans was determined to kill them for sure, Frisk had been cheering him on. Sans was their best friend, and the idea of being wiped out, taken far away from the skeleton and his family, was the best proposal they had ever hoped for. They knew one thing for certain… even if they managed to beat Chara down…

It was too late for apologies.

Chara had fought harder than Frisk had ever seen, but Sans had been prepared. He had possessed so much determination that day, to save his friends, to right the wrongs, to keep what he loved safe. At the last point, when Chara was in danger of losing their soul for good, Frisk had taken back control, and screamed in agony as Sans destroyed them. Their eyes fell closed, and they couldn't help but smile.

It was finally over. Chara wouldn't be able to hurt their friends any longer, as their host had perished.

Or so, they thought.

When Frisk had awoken again with the familiar sense of blackness hovering over them, they had screamed, cried, and begged. This couldn't have been happening. They were dead, and gone, but soon came to learn that Flowey had played a part in keeping them alive. Now, the wicked weed perched on their shoulder wherever they went, and Frisk had gazed in horror upon the damage they had done.

The underground wasn't dead… No… they were much, much worse.

They were all under Chara's command.

As the events carried on, Frisk kept a close eye on the skeleton brothers, rooting for them. Sans ended them once, he had to be able to do it again, right? They fought as hard as they could against Chara so many times, but it was never enough. They were helpless to stop this rampage.

"Dirty brother killer…" echoed in their mind as they sank to their knees in despair. They were made of LV. They were a murderer….

What had they done?

Alphys and Sans stood above a table of blueprints, formulas, and ideas, all crossed out, and written over. They were both wearing lab coats, and Papyrus sat away from them, playing with his gloves, and watching in confusion. He had no idea his brother had been so involved with science. Sans felt a pang of guilt as he looked over at him. He told Pap a lot…

But he hadn't told him everything.

After a few minutes, he took a deep breath. Alphys gazed at him nervously behind her glasses. She sensed his regret, and turned away to write a new solution, giving him the time he needed. He reached into his lab coat pocket, and his eyes went wide as he felt his hand on two pieces of paper. He pulled them out gently, examining them with care. One was of him with the human, and their friends. He couldn't help but feel his eyes well up with tears.

They had gone to the surface, and Frisk had taken them there. He had become closer to them than he had to anyone. But now? They meant nothing to him. He growled, tearing it to pieces, and throwing it to the ground as Alphys studied the fragments. He wiped his eyes, moving to the other photo. He gave a genuine smile at this one, and looked up, walking toward his brother.

Papyrus looked up at him, questioningly.

"Hey, bro… ya remember anyone here?" Sans asked, presenting it to him.

In the shot, Sans was standing in the center, shorter than all the others, in his labcoat, a huge grin on his face. A taller skeleton with hollow black eyes and a mark on his face stood behind him, one hand on his shoulder, and a blue reptile looking monster stood next, his other hand holding onto Sans as well. There were two other characters present, a female rabbit with glasses, and a clipboard, and a huge dragon looking creature with goggles on, and his jaws open in a laugh.

Papyrus stared at it for a long time, before pointing to the skeleton above Sans's left side.

"HE KINDA LOOKS LIKE US…"

"That's Gaster…" Sans answered, smiling sadly. "He was the royal scientist before Alphys was…" Alphys heard this, and turned away, her eyes shutting tight.

"WHERE IS HE NOW?" Papyrus asked, and Sans was silent for a long moment.

"He was a good friend of ours… my mentor… Alphys's mentor… a brilliant monster…" he ran a bony finger over the photo. "There was a tragic accident… with the research for the CORE…. He didn't make it… I haven't been into science since…"

Papyrus rested a comforting hand on San's back.

"I-I'M SORRY, BROTHER…" Sans nodded.

"It's okay, bro… I'm sorry I wasn't totally honest with ya… speaking of which… we need to talk…" he reached down, grabbing the photo fragments he had just made. He found the one with just Frisk's face, and showed it to Pap.

"You know this one, buddy."

"THE HUMAN…" Papyrus chattered sadly. "WHY DID THEY TURN, SANS? EVERYONE CAN BE GOOD…. THEY CAN!"

Sans felt himself sigh, and he rested a hand on Papyrus's arm.

"They were, Pap…"

Papyrus raised an eyebrow.

"WHAT DO YOU MEAN?"

Sans looked over at Alphys, who seemed hesitant, but nodded. Papyrus had to know eventually, and if this was the last timeline they had, they might as well make it now.

"What I'm gonna explain to you aint gonna make any sense… whatsoever… but you trust me, right?"

Papyrus nudged his shoulder with a smile in response, and Sans returned the grin before he began.

He told Papyrus everything.

The RESETS, the LOADS, the judgment hall, the burden. The guilt, the deaths, the fights, and he had come close to tears as he did. He explained the reason he was always so lazy, so apathetic, and he told him the reasons nothing ever mattered to him. The full story took almost an hour, and Alphys joined in with the listening, sitting on the lab floor quietly as Sans continued.

When it was over, Sans had gazed up at Papyrus with hopeful eyes, willing him to understand. The taller skeleton was silent for a very long time, before suddenly, Sans was being crushed in the tightest hug of his life. Papyrus began to cry into his shoulder.

Sans let his eyes fall closed, trying to comfort him.

"B-BROTHER…" Papyrus choked, sniffling. "IF WHAT YOU SAY IS TRUE… HOW DID YOU DO IT? WHY DID YOU KEEP GOING? WHY DIDN'T YOU TELL ME SOONER?"

"I had to keep you guys safe…" Sans murmured, holding tightly to his scarf. "Even if I did get ya to understand… that… that freak could have just RESET again… back to square one. It wasn't worth it… but now? I need you to understand. You're on our team, Pap… you gotta help us all you can…"

Papyrus loosened his hold, and Sans leaned back a little bit, looking up at him.

"YOU ARENT A LAZYBONES… NOT AT ALL…" Sans laughed.

"Come on, bro. I teleport everywhere, even if it's just a few feet. I'm the laziest." Papyrus smiled, patting his skull.

"FAIR ENOUGH."

"I- h-have something t-to say…" Alphys murmured, inching forward, guilt in her eyes. "Something I-I sh-should have told y-you long ago, Sans…"

Sans watched her curiously, and Papyrus kept his brother close.

"Shoot… seems it's the time to come clean…" he joked, but his eyes were full of interest.

"The monster you're talking about… the killer…. I-it…. Its n-not Frisk…" Alphys murmured, and Sans's eyes went wide in shock.

"W-what?"

Papyrus too was curious.

"WHAT ARE YOU TALKING ABOUT?"

Alphys pulled over the board they were drawing on, and erased it all. She grabbed a marker, and began to draw the human Sans hated so much.

"It t-took a-a lot of research… but I discovered it… th-there was no way they ch-changed their mind that often… the killer… is Chara…"

Sans's eye began to glow.

"Wh-what!? Chara? The… the first kid to fall down here? How is that even possible?"

"Your guess is as good as mine, but they're a ghost in Frisk's mind…" Alphys murmured. "Flowey… when he was still under my c-care… t-told me everything…"

"Then why didn't Frisk kill us all the first time, if Chara was always in there?"

"Because th-they gave up control wh-when they RESET… I'm not sure why they d-did it… but Chara was manipulating them. T-they still are… Sans? When you f-fight them… can you sense anything? Anything else that isn't evil?"

Sans began to think. With every fight, he always had gotten a small flicker of a second soul deep within the body of the child when he attacked. He blamed it on his mind playing tricks on him, but it suddenly hit him. Frisk… was still there? That meant that they had seen everything. They had been forced to carry out their awful actions… against their will.

"You mean to tell me that the whole time, this poor kid has been a puppet? And how in the hell are they still around?"

Alphys looked down.

"Y-yeah…"

Sans watched her intently.

"Answer my question… how is this possible?"

"Chara alone is a nightmare…. and… F-Flowey is a force n-not to be t-tampered with… b-but… t-together?"

"THERE ISN'T ANY HOPE…" Papyrus chimed in, his eyes full of fear.

"The kid's first RESET… led to all this?"

Alphys nodded.

"S-sadly…. Yes…"

Sans leaned back against his brother's sternum, and took a deep breath, his eyes falling closed. This changed everything…. What if the kid had been trying to stop? This Chara thing had caused it all… He couldn't even imagine what his old friend was going through right now.

"WHAT SHOULD WE DO NOW?" Papyrus asked, looking down at him. Sans turned his eyes to Alphys, and climbed down from his brother's hold before speaking once more.

"We figure this out. Come on… I got an idea…"

They set out to work.
