A/N: So, Gaster in gonna be in and out of this. I will have translations at the end of every chapter that he's in. This is Post-Pacifist Lady Frisk/Sans, but I might include some Mettaton/Papyrus. I haven't decided yet. I'm on the fence with them. The rest of the cast, including Monster Kid will appear throughout the story. I'll be Updating my HP story when I can.

Frisk danced away from the flying bone, her red eyes gleaming with a mix of rage and tears. Sans kept one hand in his pocket, one throwing her around like she was a rag doll. How had it come to this? Frisk was successful, she had people in her life who loved her, and here she was. Dancing with death. Before the fight, she had actually begged Sans to kill her. As they continued to fight, his mind slipped into memories of her.

The first was when she was around 13. No one had been really sure how old she was, but she had lived with Toriel for three years by then. Sans and Papyrus had been waiting by her middle school to pick her up.

"SANS, WHERE IS OUR HUMAN?" Papyrus asked, looking down at his older brother. Sans had had his eyes closed, and was beginning to doze off.

"I don't know." Sans said, shrugging. The school doors burst open, and dozens of kids walked by them. Then he saw her. Her hair was short and brown still, but she had grown in height by at least a foot. Before the brothers could call out to her, someone else did.

Frisk turned, and was met with being shoved down. She landed hard on her wrist, but she didn't cry out. The boy who had pushed her was laughing at her.

"Freak!" He yelled, starting to run away. Papyrus was at Frisk's side in an instant. While Sans stopped the bully.

"I'm okay…" She muttered to Pap. Sans gave the kid a cyan glare. He backed away, tripping as he went. Sans snickered, and walked to Papyrus. Frisk was holding her wrist.

"I knew we were friends, Kid…" He began. She smirked. "I didn't know you'd be falling for me."

Frisk laughed loudly while Papyrus went into a rant about her health and safety. She had broken her wrist in the fall, and had made it orange and blue for them.

Sans was snapped back to reality by the singing of a knife. He side stepped, and Frisk was propelled forward by the motion. He swung her up into the air, and brought her down hard. She laid on the ground for a moment, panting hard.

"Just end it..." She demanded. He looked down at her.

"No." He said. Frisk jumped up, and drew her knife again.

"Fine."

The Skeleton was jerked back to the end of the hall, a now unhurt Frisk standing at the end. He sighed, and shook his head.

"I'll end it." She promised.

His mind was faded again with memories.

This time Frisk was laying on his couch. Her hair was a bit longer, but not much. She preferred to keep it short. The 15 year old was dozing as they waited for news.

"How do you think she's doing?" She asked Sans. He was sitting on the end of the couch, buried under her feet.

"Alyphs and Undyne will be fine. They knew what they were getting into." He assured her. Papyrus was in the kitchen, cooking some pasta for them.

Sans looked over the more adult Frisk. She was still growing into the lanky body that had developed over the last year or so. She was going to be at least six feet tall, which made him laugh. She was always complaining about guys not wanting to date tall girls.

"DINNER IS SERVED." Papyrus announced, setting two steaming plates of spaghetti on the table. Sans and Frisk both tried not to wince as they smelled it. "I HOPE YOU CAN TASTE A SIGNIFCANT IMPORVEMENT." He said, sitting with his own food.

Frisk was the first to take a bite. She winced, and swallowed. She tried not to gag. Sans didn't bother touching his food, but they brothers watched her. She took a deep breathe, and began to eat the spaghetti as fast as she could. Papyrus looked over-joyed.

"Holy shit." Sans said. "That's the bravest thing I have ever seen." Frisk passed Papyrus the empty plate, and huffed. She looked green.

The door kicked open, and Undyne stood there, sweating and grinning. The look said it all. Her daughter had been born.

"Hey!" They said together. She rushed over.

"Her name is Kitty." She announced. "She has yellow skin, but-but like-really red hair like mine, and she's got really sharp teeth, and…" Undyne went on and on. Frisk escaped for a moment to throw up.

Once again, Sans was pulled out of his good times. Frisk was again laying on the floor, blood and bones around her. Her chest heaved with pain, and he knew. She had only one HP left.

"Stop this." He insisted. She looked up at him, her brown, doe-like eyes still full of pain.

"Then kill me." She begged one more time. Sans stood up, and one final blow was produced. Frisk closed her eyes.

"I'm sorry."

The bone slammed into her chest, and she chocked on the last bit of life as it left her. The skeleton leaned against the pillar, and slid to the floor. His Frisk was dead.

"Oh, now you show up." Sans glared at the anomaly next to him. "Where were you when this started?"

"And yet…" The reset button glowed in his mind. "Why?"

Sans stood up. "I'm going home."

"I don't plan to reset. Not yet, anyway." Sans walked away from Gaster. He walked away from Frisk's body, and the pain that burying it would bring. He simply walked away from it all. Undyne had been both lucky, and unlucky in Frisk's killing spree.

Kitty had gone missing at the beginning of it all, and while no one knew who had done it, she had died. Undyne had been out looking for her when Alyphs had been killed. She, Sans, and Asgore were some of the only monsters left.

Months went by. Sans eventually buried Frisk, and lived alone. He had made a make shift grave for the others that he knew as well. Alyphs was next to Kitty, and Papyrus was on the other side of Frisk. Undyne would knock her headstone down at least once a month. Sans would fix it, and Undyne would swear should wouldn't do it again. He didn't care.

"Been a while, Kid." Sans said, sitting down in front of her grave. He touched Papyrus', and sighed. "G says I shouldn't reset. That it would make me relive this pain over again, but…Maybe he's wrong. Maybe I can fix it."

"Undyne hates you still. She doesn't know what happened, but neither do I. I wish I did." Sans reached into his sweatshirt, and pulled out a cigarette. "I know you hate smoking, but it helps. Besides, I don't have lungs." He laughed to himself.

"Why do you always come at the most convenient time?" Sans looked at him. Gaster loomed over the graves.

"Good."

"Of course you must."

The first breathe she had taken in months filled her lungs with fear, pain, and at the same time, joy. Her heart was pounding in her chest, but she knew that she hadn't done this. Frisk laid in bed for a moment, and waited to hear the distant snoring of Sans. Papyrus would already be awake, and getting ready for his daily adventures with Kitty.

She sat up. This was before. She hadn't gone insane yet. Frisk ran her hands through her hair, and looked at them. They were whole, and not covered in the dust…

"FRISK! KITTY WILL BE HERE ANY MOMENT!" Papyrus knocked. She was grateful that he didn't know about the timelines like she did.

"Yeah, just let me get dressed, Pap." She called back, getting up.

"WELL, HURRY. I MADE BREAKFAST." He said proudly. She tried her best not to groan. The room next to hers was silent.

Frisk clambered up, feeling immensely appreciative of her living body. There was a soft knock, just as she was pulling on her favorite stripped shirt.

"Come in." She called automatically. The door opened slowly, and she saw a timid looking face, as if her Sans was half convinced that the reset hadn't worked. He broke into his usual grin when he saw her.

"You're…"

"I am." She leaned against her desk. She felt Sans' eyes tracing every inch of her, looking for some sign of wear, some sign of destruction. When he found none, he strode over, and puller her down to kiss him.

That was his only problem with dating her. He'd never admit that it tore him apart being around seven inches shorter than she was. Frisk felt more than just alive, but glad, and remorseful.

"Did G warn you?" She asked him, sitting on the floor. He plopped down next to her.

"Of course he did. He was all like 'If you do this, it's gonna have dire consequences.' Hey, No 'bones' about it." He winked at Frisk, who snickered. They sat silently for a while, until the apartment was filled with screaming, and the slamming of a spear on the floor.

"Kitty's here." They said together, getting up. Sans tried not to snigger at his brother, who had Kitty on his shoulders already.

The little girl looked much like Undyne in shape, but her skin was yellow, and she had a tail. Her red hair clashed gloriously with the awful blue shirt she favored so highly, as it had a giant K on it. Her glasses were one of the only other things that connected her to Alyphs.

"Hi uncle Sans!" She laughed. It was the middle of June, so she and papyrus disappeared every day to go on adventures and fight hideous human beasts. They didn't know, or at least pretended not to know, that Frisk and Sans took turns following them, making sure that they were safe.

Everything was fine, for right then. Frisk knew as long as she and Sans prevented her from losing her mind, she'd be okay.
