A/N: Okay, this is my first Undertale story, yes, I know it's pretty fast paced right now. It will slow down a bit in the next few chapters, just needed to have something happen here. Sorry for the short chapter...So, please enjoy, comment, leave review please! I could definitely use the constructive criticism right now.

Frisk was thrown back against the wall of the sunlit hallway. They knew that all they had to do was finish the fight, and then they could RESET and start over. Chara had lost control, and Frisk was the one with all the power now. But it had happened too late for all but one to have been murdered. "You can't understand how this feels..." Frisk felt their sins crawling on their back as Sans' eye flashed blue and a Gaster Blaster materialized, charging the blue beam of light that was about to incinerate them. This was it. Chara had never gotten them past this, this was her one chance-

"To know that one day, it's all going to be RESET." If they could time this just right, they could make it, they could fix everything- "Watching your family die, over, and over, and over, just for more data in the file..." Frisk prepared themselves, tightening their grip on the dusty knife. Sans dropped his hand. Frisk jumped. The blaster fired. In the flash of a second, Frisk jumped, dodging the laser and launching off of a piece of flying rubble and landed on the Blaster's muzzle. It looked confused, but still hostile as it began growling at them.

Sans was waiting for the dust to clear, and for their dead body to once again be lying there, waiting for a RESET, so he didn't notice Frisk running along the Gaster Blasters head, and leaping off it, landing with a bounce on the tiled floor behind Sans. The skeleton whipped around, expecting the bloodied knife to come slashing at him, but instead he heard the pattering of feet fading down the hallway behind him. He looked up at his Blaster, and they shared a confused look. The kid had never done this before. Fixing a look of anger on his skull, Sans vaporized the Blaster and took a quick 'shortcut' to where he thought the kid would be by now. He got there just in time to see a blue sweater disappearing down the corridor. He growled, and took off running after them, yelling "If you think you're gonna get to Asgore without fighting me, you'd better think twice kiddo!"

Frisk knew that they didn't have much time. It would only take Sans a few minutes to catch them, and this was their only hope of beating him without killing him, and MERCY was off the table. Sans would never forgive them, but they wanted a way to find a TRUE RESET, so they could start over. Completely.

Chara was at a loss. Her partner had revolted, and had eventually won. Frisk was going to teach her...MERCY. Maybe she could be good again, but no one would ever trust her, and WHERE IS THIS KID GOING ANYWAY? She realized that she was being dragged along by the mind rope that connected the two, and Frisk wasn't even fighting Sans, and they hadn't killed him either, because she could hear the idiot bellowing down the hall after them. Chara went back a ways to check on his progress, and was prevented from doing so as Frisk started running at high speed down long flight of stairs. She let out a yelp of shock as the invisible rope tightened and yanked her down to Frisk's level. Well, might as well try and find out what they're up to, they've never tried this move before. Chara mused as she floated alongside Frisk as they hurtled down the steps, their breath coming in short gasps now. She began looking around at their surroundings, and quickly realized where they were and what Frisk was planning. "Frisk, NO! They can't help you, this won't work, please-!" She screamed, her panicky voice echoing with a ghostly tone to it. She clawed at her head, fighting the memories that were flooding in.

Frisk was exhausted, but they had to keep going. They weren't sure if this was going to work, but they had to at least try. They stumbled down the last stairs, taking two at a time, and hit the ground running (and gasping for air). They rushed past old, broken down machines that'd been abandoned for years. Frisk scanned the hallways that branched off for something. They knew Sans was closing in.

Sans bounded down the steps, looking a bit crazed as his eye burned brighter than ever. He started to summon all his magic as he ran, so he could get a jump start on the kid. A tear spilled out of his normal eye socket as he thought about how he and Frisk had once been friends, family, even-but that didn't matter anymore. He had to do it. He had to kill this child before they could get whatever it was they were looking for. He wasn't sure what it was, but it couldn't be good.

Frisk spied a faint, multicolored glow coming from one of the passages. They veered suddenly, earning themselves a screech of protest from Chara, who screamed "NO! Frisk, you don't know what'll happen, it's dangerous, I don't even know if it's possible! I hate to say it, but better to be killed but the blue idiot than do THIS!" The ghost was beside herself. "T-The, RESETS, it'll be changed forever! You might not survive, and—ARE YOU LISTENING TO ME!?" Frisk ignored Chara's shrieking and barreled down the hall until she came to seven chambers, each containing a different colored human soul.

Sans made it down the hall, and decided that a surprise attack is always better. He paused, panting, and warped out of sight and into the soul room. He made his silent entrance and was just about to raise a bone minefield, but he stopped, startled at what he was seeing. The kid was just standing there in front of the soul cases, like they were planning on smashing them or something. The skeleton lowered his hand a bit, and decided to watch Frisk for a minute, to see what they would do.

Chara was still ranting to Frisk, but it appeared as if they were purposefully ignoring her now, so she let up. Frisk had the look of someone who was about to put their hand into a bowl of snakes. Frisk then looked up at Chara, and murmured, "Chara?...I'm sorry..." Then they raised their knife, and plunged it into the control pad that sealed the souls inside, shattering it. "NO!" Chara screamed, as the souls were released and began glowing more and more intensely. "Frisk, get back! They're going to-!"
