A certain sacrifice

- You are a weird one, kiddo. Sans closely looked at a guy that was definetely taller than Papyrus, even thought the age was lower from the theoretical one. He stood five meters away from the skeleton, holding a knife in his right hand, and an amulet in the left. Last Corridor. Human that stood in front of him was nothing more but a bloodthirsty maniac. After all, it was him who killed almost the entire Underground with no mercy. But right now he was doing something strange... Sans shrugs, after which (just like he felt) he smiled): - Even though the ash is falling from your shoulders, you don't stop sparing me. Seriously, how long does this even go? Mind giving a hint? Right now a human that mercilessly slayed monsters, tryhardedly continued to spare Sans every time he gave him the option of mercy. Of course this "mercy" ended up all the same: the skeleton impaled the guy with bones, which, in the end, kill him. But he didn't see even a glimpse of anger nor annoyance on his face. - ...seventy seventh. - Oh? - Sans was pleasantly surprised by a sudden talk from the guy. - So you do know how to talk, eh? - ... The guy silently looked at the floor. He didn't even dare to lift up his head in order to look at empty eyes of the skeleton. Of the skeleton that didn't stop smiling. - But I still can't understand one thing... - scratched the back of his head Sans. - Why do you keep "sparing" me? Isn't it just easier for you to continue the fight and end... your work? The next action shocked the monster even more: the guy suddenly fell on his knees and dropped the knife. Tears fell from his eyes, after which he lifted up his head. In the eyes full of tears Sans saw... something that he never expected to see anymore. Humanity. - Woah, woah, slow down, kid, I know that sins are crawling on your back, but don't go this overboard... - the skeleton even tried to calm the guy down, but he didn't stop crying. Then the guy did something unbelivable: he ONCE AGAIN fell on the knees in front of the monster. - Forgive me, Sans! - the guy screamed, sobbing like never before. - Forgive me, the dirty murderer and a cruel heartless maniac! I don't deserve forgiveness! ...something tells Sans that this time will be much different than the previous ones. - Okay, buddy, have you calmed down? Sans and the guy sat on the opposite sides of the same column. The human already stopped crying, but tears continued to flow through his cheeks uncontrollably. - Yes... He took in his left arm an amulet, after which he opened it. In it was an old photo. An old photo of the first human that fell on the Underground, and also of the only son of king Asgore - Asriel. - Sans... - M? Wanna say something? I'm all ears. This, on first glance, ordinary pun easened up the entire atmosphere, making the dialogue between them more "free". The guy slightly chuckled at it, which, on one side, did make Sans happy, but on the other... a heartless maniac was laughing at it... - ...please answer my question, Sans, - the guy continued after he stopped laughing. - If you had Determination, like me... would you have tried to give everyone a happy ending? This question caught the skeleton off-guard. A brotherkiller says something about pacifism? - My hearing must be deceiving me, - he once again made a pun after he rehabilitated from this sudden miniscule bewilderment. - Don't even ask! Sans was about to continue yapping about how he will open the barries that hatefully keeps monsters from humans, but immediately stopped. For all his life he was but a bunch of lazybones that slept even on the workplace of his. This turn of events made him think that for all this short time he started to become someone else... - ...that's a good answer. The guy clunged up to the column, after which he sighed. - But I meant an actual happy ending. Where everyone with no exceptions witnessed on themselves how it feels to be happy. - Okay, kid, you definetely confused me here... - Sans said again, once more scratching the back of his head, not understanding what does he mean by that. - ... To that he didn't answer anything. He just looked at the amulet once more, after which another tear fell from his eyes. - I remember when Flowey told me a history while I was walking to the Final Corridor. A history about two kids. - ..! At that moment Sans understood everything. It can't be... - Don't tell me that you... - If the body of a being - human or monster, not important - had managed to survive somewhere deep, then... it would be logical to assume that you can revive them. The skeleton did not understand. If he wants to give everyone a happy ending, including the revival of even Chara and Asriel, then why... - I'm sure you don't understand the reason why I decided to kill every single one of you... and that's okay. The guy smiled slightly, after which he turned his head to Sans. - But unfortunately, I can't do it without genocide... - Can you then explain the train of thoughts you're having there, pal? - Sans grinned slightly without turning to the guy's side. - ...there is a legend that Chara is a demon that comes when people call her name. Or his... no one really knows and it's not that important. If you were to give Chara your Soul, after that you will be connected with them, essentially turning into the vessel of this "demon". The skeleton listened carefully, trying to comprehend the meaning the guy puts behind his own words. - If you disagree on selling your Soul to Chara, then they will try to kill you, after which they'll still take your Soul. But what if you tried to change their opinion on the matter? Convince them that genocide is not the answer? - To be completely honest, kiddo... I still didn't fully understand your ideas. - And you really shouldn't, Sans. Suddenly, the guy chuckled. - I just need to change the course so that they'll sign an agreement with me. They don't take my Soul, and after the Reset I give them one third of it. - Wait... one third? This once more confused Sans. Only a third of the Soul? Will Chara - or Asriel and this guy for this matter - even survive, if such an action would've worked? - Asriel also needs a Soul, after all, am I right? The guy sighed silently. - Of course that means that each of parts of my Souls will "work overtime", supporting the lives of three bodies, but... as long as they're alive... it's all worth it. The very last bits of doubt started to evaporate inside Sans' soul. This explains a lot. Even though he tried to convince himself that this guy is a ruthless, bloodthisrty maniac, but in reality he is much more than uncondenced bloodlust. After all, the very first question that he asked the guy in the very beginning of their first fight... had finally gotten its answer. - In that case... Sans suddenly stood up. The guy was slightly surprised by this. - Let's do it this way, pal. The guy stood up as well. - If you really want to give every single monster - and Chara too - a happy ending, then I'll let you kill me. But promise me that you won't forget about our dialogue, and especially about your own goal, okay? At that moment the right eye of the skeleton turned blue: - Or else you know what. - Yeah, I understand. Sans' eye immediately died out and he shrugged, after which he once again (like he was feeling it) smiled: - This definetely needs a secret word then. The guy kneeled down a little, giving Sans a chance at whispering the word to his ear. He said something, and the guy barely managed to hold his laughter back. - Once we'll see each other at the other side, tell me this word, okay? - Gotcha, Sans, - the guy smiled. - Well, then... Sans spread out his arms. - You can continue your journey, my friend. "Sans spares you" After these words the skeleton was hit with a deadly knife wound. But this time both knew that such an action is but a preparation for the future. For the future, in which everone - even the one who died a long, long time ago - could grasp the happiness.
