We finally reach the beginning of the interesting part! Really hope someone is appreciating this garbage of mine, and if you don't I DON'T CARE
Geez, what a wrecked universe. The whole underground seemed cracked, mixed, with pieces missing here and there. Seriously, the name was the description of the place. Under decay. The universe had one timeline, and it was a genocide one. The human seemed to miss only their skelebud. Sam said that if the human kills him, or if Sans kills the human, the whole timeline will reset, becoming even more broken than now. They had to interrupt this cycle by killing both. The universe then will probably collapse, so Sam gave them the ability to travel between the universes. They will probably end up all in different universes because they never teleported, but Sam always knows where they are. Muffet took a deep breath before slowly sneaking behind the skeleton. Maddy and Grillby hid, in case Muffet failed. If Sans thinks that she’s the only threat, then it'll be easier to eliminate him. He was sitting on his centry stationin the middle of the last corridor, apparently focused on a little origami they were doing (was it a crane?). Oh well, only apparently. In fact, the moment she moved to stab him, the skeleton turned around and pointed Asgore’s trident at her. Muffet retreated a bit, and her co-workers remained hidden. Sans raised a brow and asked: “Since when you help the human killing your own kind Muffet?”. The spider relaxed. "I don't help them, I assure you. I'm here to end your sufferences, Sans" Muffet said. Saying stuff with this mysterious way to talk was kinda funny. It sounded like she was part of some sort of cult or able to do something strange, and the enemy focused all themselves on her moves. "What are you talking about?" He asked. Muffet snickered and answered: "isn't it obvious? I want to kill you and the human. To end this torturing cycle". Sans' expression got darker. "I'm sorry to tell you that it won't work. If you kill the human, they will come back" he explained. "Oh, don't worry. If I kill them, there is no way they can come back. And neither you will" she answered. Sans seemed evaluating the whole thing, which was interesting because she was telling him she could kill him forever. Muffet saw the human coming in and smiled. "oh, good day to you dear! We were talking about you!". Without giving them the time to react, she summoned a magic spider and attacked them. With one hit, the human died. And they didn't come back. Sans turned around to see the body of the human lying on the ground, not resetting as they usually did. "So, as I was saying…". Muffet killed the skeleton easily. They didn't even turn around to see her before dusting away. Woah, the bud must have been heavily traumatized. Maddy came out huffing. "c'mon! He didn't even try to defend himself! I wanted to fight…" she commented. Grillby came out as well. He looked worried. "What's the matter?" Muffet asked him. "I'm worried about this 'teleporting' thing" he explained. "What if we end up stuck in a place where no one can reach us? I remember Sam talking about very dangerous AU's and places….". The room shook, and strange cracks started opening on the walls and in the air. Maddy hit him on the shoulder and exclaimed: "sheesh, Grillbz! Don't worry, we'll stick up together! If we get lost, then we'll do it together". Muffet admired their confidence, but the idea of getting lost somewhere strange wasn't the best thing… Before risking any further, she took both the other monsters from the shoulders and tried to focus on the place she wanted to reach. This is what Sam told them to do. She focused on their kitchen. It was easy to remember. They all felt like a cold lightning passed through them, and then silence.
It took a few seconds to get the eyes used to the new illumination. Muffet looked around. It appeared to be Sam’s kitch-... no, wait. It was messier, the table was missing, and it had an unproportionately tall sink. Maddy exclaimed: “i-i know this place! It was the entrance to my house!”. “The entrance? It’s a kitchen, and I don't see doors…” the spider commented. Maddy opened the sink, and they saw… nothing. Just a regular sink. “What? There was a tunnel! And-and an altar! And…”. Grillby explained: “this is Sans and Papyrus’ kitchen. I’ve been here once. This isn't our home. We’re probably in a universe where Maddy lives somewhere else”. Oh great. Right in the mouth of the wolf. “Should we try again?” Muffet asked. Grillby shook their head. “Too late”. He looked at someone outside of the kitchen. There was a tall skeleton with an orange hoodie, a pair of greenish jeans that reached the knees and a confused look. “Uh… Muff? Weren’t you at your restaurant a few seconds ago? Who are they? And why are you in my kitchen?” he asked. Oh, sure. This must be Underswap Papyrus. “Yeah, no. I’m not the Muffet you know. And those are my… friends. We were traveling but we accidentally ended up in your kitchen. Sorry” she explained. As much as she remembers, Underswap Papyrus should know about the whole multiverse thing. A deep, annoyed huff confirmed it. “God, not again. I got tired of all that stuff. Please, just… go away if you can”. Muffet was about to tell him that they would have been more than pleased to go away, but Sam popped in from behind the tall skeleton. “Hey guys, I found you! How the hell did you end up here? Oh, hi Paps” they said. Papyrus seemed everything but pleased to see them. “It sounded like a familiar situation” he commented, summoning a bone. “hey-Hey! We never wanted to harm you, man!” the grey human exclaimed. “Go away and don’t come back, or I'll give you what I gave you last time, and I'll double it” he declared. Sam giggled. “Still? It was, like, fifty timelines ago, geez! You really are a vengeful person, aren’t you? Whatever. Let’s go guys, I don’t want to almost die today”. The trio walked towards the portal Sam kept open, while the skeleton stared at them, ready to kill them if necessary. He remained on alert even while Sam closed the portal.
They found themselves in THEIR kitchen this time, finally. Maddy immediately asked: “the hell were you two talking about? Did you kill him once?”. Sam sighed and explained: “No. I tried to kill his brother Sans, obviously. I was still convinced to be able to kill someone by myself, but… I’ve never been a fighter. I just can’t fight. I can defend myself, but I literally don’t have any ATK. I can’t hurt anyone even with a weapon, for some reason. Still, he doesn’t trust me. He doesn’t like my code abilities, and fears that I might be able to harm his brother with them”. “Can’t you just raise it?” Muffet asked. Sam smiled and said: “I can modify stats that already exist. I don’t even have the ATK stat! For the code, I am NOT supposed to fight. It’s not even an option! That’s also why I asked you for help…”. Grillby asked: "so Underswap Sans never died, right?". "Exactly. I'll ask you to kill him in one of the next missions. Better leave some time between this sudden meeting and his death. I honestly don't want Swap Paps in the middle of the fight. He is such a strong skeleton, he could make everything way harder".
A thought that never came in their minds kicked in.
"But… What about him?"Muffet asked. "I mean, I know Sans always ends up making a wrong choice, but… Papyrus seemed to care a lot for his brother. Wouldn't we end up creating a possible story trying to prevent another one? What if, when we kill Sans, he tries to find us and kill us?". Sam hummed, then answered quietly: "... yes, this is one of the many risks. But by cutting down a tree at the roots, you make sure it doesn't grow back. Is it better to have one bad story or thousands? We sometimes have to go by compromises to reach a goal. Will we appear as the evil ones? Probably. But we know we are doing the right thing". Muffet wasn't too sure about it. Sam's anwer wasn't too convincing. But then, they were right. They won't be seen as heroes, but they were doing what was necessary.
At least, that's what Sam thought.
I tried to represent Decay sans as best as i could. Hope i got him right... The whole Underdecay is from @little-noko
Aaand that's it for now! For some reason, I don't like too much how this chapter came out. I feel like I could have done better. Maybe one day I'll stop by and rewrite it.
And HERE ARE THE BOYS! I may not be the best artist, but i tried! Their personalities remain more or less the same as the original
