"How could you do something like that, this poor innocent child did nothing to you and you ruthlessly slaughtered them." Toriel stated angrily as she launched another group of fireballs towards Sans forcing him to teleport behind her to dodge them.

"She did nothing huh, funny because I have a different opinion." Sans mentioned as a skull with glowing blue eyes appeared above him and he extended his open hand towards Toriel. "The kid's gone through a really bad time, worse than anything you could even imagine."

As he said that Sans closed his hand and the skull launched a blue laser at Toriel sending her crashing into a wall before she got up and turned towards Sans only for him to have already disappeared again.

"Worse than being trapped underground, worse than being forced to watch each and every human who falls down willingly walk to their death?" Toriel questioned as she launched more fireballs that began bouncing off of the walls as they tried to hit Sans.

"Far worse." Sans replied as more bones struck Toriel. The kid went through so…

Suddenly a stray fireball hit Sans and he collapsed fully expecting to turn to dust when suddenly Chara's soul began to glow and Sans felt his HP go from zero back up to his full one HP.

"I thought you were a better person, our daily conversations through the door made me come to respect you and enjoy talking with you." Toriel revealed sadly. "Now I see, it was all a ploy to get into the Ruins."

"If that's what you have to tell yourself." Sans noted calmly. Still, I should be dust so why wasn't I killed? Wait could it have been the kid, so Chara wants me alive so I can gather more LOVE, normally I'd object to that but considering the kid probably just wants to come back I'll let it slide this one timeline.

"I should have known better." Toriel admitted before laughing. "You're one of them, all you care about is your freedom and if that means taking innocent lives you…"

"You're half right." Sans interrupted as his eyes turned black. "It's true, I do care about our freedom. I care about it a lot more than you can possibly realize."

"Our freedom, anyone who cares about freeing us wouldn't slaughter so many of his own kind." Toriel challenged. "It's your own freedom you care about and everyone else can remain trapped here, I never would have imagined anyone could be worse than Asgore but you've proven me wrong."

Frisk smiled as she noticed the cheese and the mouse hole knowing the mouse would be eating the cheese soon enough before walking into the next room to see a familiar ghost in front of her.

"ZZZZZZZZZZZZZZZZZZZZ." the ghost stated. "Are they gone?"

"Um… excuse me, but can you please move so I can get past?" Frisk requested before the ghost stopped lying down and started to cry. "Oh, it's ok you don't need to cry."

"Huh, oh who are you?" the ghost asked curiously.

"My name's Frisk, it's nice to meet you." Frisk introduced herself. "What's your name?"

"Me, I'm Napstablook." the ghost answered. "Can I show you something?"

"Sure, what is it Napstablook?" Frisk inquired with a smile.

As Frisk asked that Napstablook used a bit of magic to turn his tears into a hat. "I call it Dapper Blook, what do you think?"

"Wow, that's really cool." Frisk complimented.

"Gee, I usually come to the Ruins because I don't plan on meeting anybody but today I met somebody nice." Napstablook noted. "Oh, I'm in your way, aren't I? Let me get out of your way."

As he said that Napstablook disappeared causing Frisk to frown slightly before walking through to the next room.

Toriel was breathing heavily with countless burns from Sans blasters and bones that had hit her repeatedly and yet aside from that one strike she'd been unable to hit him once.

"Sorry, but it's like I told you everything I'm doing is for our freedom. Even if it doesn't look like it from…" Sans started only for Toriel to throw more fireballs at him though they were moving much slower. "Looks to me like this is almost over."

"Even if you somehow manage to kill me I won't let you harm the rest of them…" Toriel stated weakly. "I'll destroy the exit from the Ruins so the others will be safe from your…"

"The door was sealed when I got in, even if you destroy it I can get out." Sans pointed out as he saw Toriel's face fall as the realization that nothing she did would help finally hit her and she gave up. "Sorry, old lady I wish I could say you'd understand but well…"

As he said that Sans created another blaster before closing his eyes as it fired another blast at Toriel sending her crashing into a wall of the Ruins.

"Then everything I've done, I really am pathetic, aren't I?" Totiel asked weakly.

"Not a bit, you're a good person." Sans answered. "That's why I'm doing this."

With those words Sans launched one final blast at Toriel, destroying her as her soul appeared for a few brief seconds before shattering.

Chara's Soul LV 5

That was just the Ruins and already I'm… Sans thought as he looked at the dust all around him. "Just beyond that door is Snowdin and… Papyrus."

Sans felt his soul tremble at the thought of what he had to do next but he'd promised Frisk she wouldn't have to go through this kind of thing again, even if doing it himself was the worst torture possible as he walked to the door and without looking back he exited the Ruins.

Frisk continued through the Ruins before reaching a room with six cracked areas on the floor as she closed her eyes thoughtfully before walking over and falling through one of them only to notice a pink ribbon that she tied around her hair as she walked up the nearby stairs before trying another spot as she fell only to see Napstablook.

"Oh, hi." Frisk smiled. "Did you fall too?"

"Yes, I was walking along and then I fell down here." Napstablook answered. "Oh wait, I'm a ghost which means I can just float back up."

"Yeah, that's really lucky for you." Frisk smiled. "Oh, do you know where the switch to get to the next room is Napstablook?"

"Oh, I think I saw a switch in that room just to the north of us." Napstablook answered. "Well I should go; it was nice to see you again."

"It was nice to see you too." Frisk smiled as Naptablook flew off and she went to the spot he suggested and pulled the switch before walking through the next room and continuing through the puzzles with a smile on her face before entering a room with a single tree without a single leaf on its branches as her phone ran and Toriel walked up to her in surprise.

"My child, what are you doing here?" Toriel asked. "Are you hurt?"

"No, but I wanted to see you again mom. You're really nice." Frisk answered.

"I see, well I'm very impressed that you made it all this way. I suppose there's no use hiding it any longer, I have a few surprises for you my child." Toriel smiled as she took Frisk's hand and the two of them walked into a small house. "This is my home, you're more than welcome to stay here with me."

I really wish I could, but I promised Sans I would be there to break the barrier so I can't. Frisk thought sadly. "Huh, do I smell something burning mom?"

Hearing that Toriel's eyes widened as she quickly apologized to Frisk and hurried to the kitchen only for Frisk to follow her.

"I'm sorry, I didn't expect you to get here quite so quickly so it's a bit of a mess." Toriel apologized. "It may take a bit longer for the pie to cool. Since it's your first night here I decided to hold off on snail pie for today."

"Thank you, but actually…" Frisk started hesitantly before looking down. "Actually, is it ok if I lie down for a while first?"

"Of course my child, come let me show you to your room." Toriel smiled before taking Frisk's hand and walking out of the kitchen and down the hall to a door. "Here you are."

"Thanks mom." Frisk smiled before walking into the room and getting into the bed. "I promise Sans, this is going to be the last time we go through this."

As Frisk said that she closed her eyes and fell asleep.

A few hours had passed since Frisk went to sleep and she was slowly waking up only to see a piece of butterscotch-cinnamon pie on a plate next to her wrapped up tightly in plastic to keep it fresh.

Mom, I'm sorry but I have to leave now, Frisk thought sadly as she placed the pie in a bag she had with her and walked out of the room and approached Toriel who was sitting in a rocking chair reading a book.

"Oh, good morning my child. Are you feeling well rested now?" Toriel inquired with a smile.

"Yes I am, but actually I wanted to ask how to leave the Ruins." Frisk mentioned quietly.

"What, why would you want to leave the Ruins my child?" Toriel asked hesitantly.

"I made a promise that I need to keep." Frisk answered. "If I could stay here with you I would, but I can't."

Toriel just looked down sadly. "I have to do something, stay here."

With those words Toriel walked out of the room and went downstairs as Frisk followed her knowing what she was planning on doing as the two of them approached the exit to the Ruins.

"Mom, I wish I could stay but…" Frisk started only for Toriel to turn to her with her hands glowing with fire magic.

"If you truly have to leave then proof yourself, proof to me you're strong enough to survive out there." Toriel stated before launching fireballs towards Frisk only for her to dodge them and spare Toriel.

"Mom, I won't fight you but I have to go. Please just understand." Frisk told her. "It's what needs to happen."

"It's far too dangerous, if you go out there they… Asgore will kill you and take your soul." Toriel stated.

"I'll be ok, you taught me that every fight has a solution and I promise nothing bad will happen to me." Frisk smiled as Toriel paused. "I know it's dangerous out there but right now I need to go so I can fulfill that promise I made to one of my closest friends."

"My child… I…" Toriel started weakly.

"You don't have to worry mom; I promise I'll be ok." Frisk reassured her with a smile as Toriel just smiled sadly.

"I suppose you have a point, but my child if you must leave I have a difficult request to ask of you." Toriel said quietly. "Once you leave the Ruins, you are to not return."

Frisk teared up slightly as Toriel said that but she wiped them away. "Ok, I promise."

Toriel nodded before pulling Frisk into a tight hug and walking back only to pause and glance back before walking off.

"This is it, the rest of the Underground is past that door. Just a little longer and we'll all be free for good." Frisk said with determination as she exited the Ruins.

(Sans has slaughtered everyone in the Ruins including Toriel, and Frisk has spared them all in a separate timeline. Next chapter Frisk will encounter two familiar faces and Sans will begin to realize the weight of his actions. As always any reviews or critique is appreciated.)
