Here's part 2 of the 4 part series! Hope you enjoy!

Sans sighed heavily when the kid entered the hall. He had been dreading this ever since he had first seen that human, way back in the snowy forest. He hated fighting, but this was inevitable. And unbeatable. Sans was just a monster. When it came down to it, no matter how many tricks he pulled out of his sleeve or however many times he beat him, the kid would win. Humans were just too powerful. One of these times Sans would slip, he would die, and the whole process would continue, only to happen again.

Or had it happened already?

The kid looked angry. Well, angrier than usual. Sans must have defeated them already. If he had to guess, this was just the first time the kid had died. One of many. Maybe it would be enough, though. Maybe Sans could kill the human enough times that maybe they would just give up. Maybe he could make them think that it would be impossible to get through him. It was just a bluff, but it might work. Sans just had to throw everything at the human and hope it would be enough to break their spirit.

God, this time travel stuff was such a pain in the butt. That kid could lose an infinite number of times, and keep coming back for more. Sans could only lose once. ONCE. He couldn't afford to slip up. He just had to hope he could convince the kid it wasn't worth it to keep trying.

He could only hope.

"Heya." Sans said when the kid drew close. "You look frustrated about something. Guess I'm pretty good at my job, huh?"

Then the battle started, as it had before. And how it would again. Sans always hated fighting. He sighed again. "It's a beautiful day outside. Birds are singing. Flowers are blooming. On days like these, kids like you…. should be burning in hell!"

He let loose his strongest attack, sending a flurry of bones and Gaster Blasters to destroy the child's soul. It was his only hope of defeating them. To his disappointment, the kid survived handily, although they were hit a couple of times. But not as much as Sans had hoped for. They were learning.

"Anyway, as I was saying, it's a nice day out. Why not relax and take a load off?"

The kid responded by attacking savagely, but Sans dodged easily. It paid to be so fast.

"Our reports showed a massive anomaly in the timespace continuum." Sans said to the human, not expecting an answer. "Timelines jumping left and right. Stopping and starting…" Sans attacked again, but failed to hit the human this time. The human responded, missing again. "Until suddenly, everything ends." Sans said, following it with another attack. This time the human took some serious damage, but wasn't quite dead yet. What a shame. Dying now would help a lot to convince the human that Sans wasn't worth it.

The human attacked, again missing. "Heh heh heh." Sans chuckled. "That's your fault, isn't it?" Sans attacked again, and to his relief this time the human was killed. The soul of the kid shattered and then….

Sans sighed heavily when the kid entered the hall. He had been dreading this ever since he had first seen that human, way back in the snowy forest. He hated fighting, but this- wait. He had definitely been here before. They had already fought. But how many times?

"Hmm. That expression…" Sans said. "That's the expression of someone who's died twice in a row. Suffice to say, you look really… unsatisfied. All right. How 'bout we make it a third?" Sans sighed again. "It's a beautiful day outside. Birds are singing. Flowers are blooming. On days like these, kids like you…. should be burning in hell!" Sans unleashed his most powerful attack, and was shocked to see that it had no effect on the child at all. This was going to suck. "Ready?"

The child attacked, but Sans dodged easily. "What? You think I'm just going to stand there and take it?" Sans attacked, no luck. The human countered. No luck for them either. "Our reports showed a massive anomaly in the timespace continuum. Timelines jumping left and right. Stopping and starting…" Sans attacked. He nicked the human, but didn't do much. It wasn't enough. The human attacked, but Sans dodged. "Until suddenly, everything ends." Sans attacked, doing nothing this time. The human was learning. They attacked, the viciousness still very much there. They wanted nothing more than to kill Sans at all costs. What made someone like this? Thirsting off of the deaths of others…. What a miserable existence.

"Heh heh heh." Sans chuckled. "That's your fault, isn't it?" he attacked, trying to find a way to hurt the human. He had to win. They followed that with an attack of their own, missing once more. "You can't understand how this feels." Sans attacked, hoping to catch the child this time. Only some luck. Sans dodged another attack from the human. "Knowing that one day, without any warning… it's all going to be reset." Attack, counter attack. "Look, I gave up trying to go back a long time ago." Attack, counter attack. "And getting to the surface doesn't really appeal anymore either." Attack, counter attack. Bit by bit Sans was wearing away at the human. "Cause even if we do… we'll end up right back here, without any memory of it, right?" Attack, and Sans was relieved to finally see the soul of the human shatter. He had won. Maybe things would stay…

Sans sighed heavily when the kid entered the hall. He had been dreading this ever since he had first seen that human, way back in the snowy for- He had been here before. Definitely been here before.

"Hmm. That expression…" Sans said. "That's the expression of someone who has died thrice in a row. Hey, what comes after 'thrice', anyway? Wanna help me find out?" He sighed again. "It's a beautiful day outside. Birds are singing. Flowers are blooming. On days like these, kids like you…. should be burning in hell!" He attacked, but it might as well have been the flowers he had mentioned that he was throwing at the human. Nothing came even close. "Here we go." The kid attacked. Way off. Our reports showed a massive anomaly in the timespace continuum. Timelines jumping left and right. Stopping and starting…" Sans attacked, did nothing. Luckily the kid did the same. "Until suddenly, everything ends." Attack, counter attack. "Heh heh heh." Sans chuckled. "That's your fault, isn't it?" Attack, and the angry response. "You can't understand how this feels." Attack, counter attack. Sans realized that he still hadn't hit the human a single time. He began to grow worried. There was no way that they could last the whole battle, right? Not this early. They weren't that good, were they? "Knowing that one day, without any warning… it's all going to be reset." Attack, and counter attack. "Look, I gave up trying to go back a long time ago." Attack, counter attack. Finally, Sans hit the human. It wasn't much, but it was something. "And getting to the surface doesn't really appeal anymore either." Attack, counter attack. Cause even if we do… we'll end up right back here, without any memory of it, right?" Attack, counter attack. Another hit on the human. A little bit closer to victory. At least, for this particular battle. "To be blunt… it makes it hard for me to give it my all." Attack, counter attack. "Or is that just an excuse for being lazy? Hell if I know." Attack, and counter attack. "All I know is… seeing what comes next… I can't afford not to care anymore." Attack. Sans wondered about something. Maybe if he offered something that the kid sorely needed, maybe they just might take it. Counter attack. Yet again another miss. "Ugh, that being said… you, uh, really like swinging that thing around, huh? … listen."

Sans attacked, but before the human could respond in kind, Sans said, "I know you didn't answer me before, but… somewhere in there. I can feel it. There's a glimmer of a good person inside of you. The memory of someone who once wanted to do the right thing. Someone who, in another time, might have even been… a friend? C'mon buddy. Do you remember me? Please, if you're listening… let's forget all of this, ok? Just lay down your weapon, and… well, my job will be a lot easier." Sans studied the human. They seemed to be conflicted, as though they were actually considering Sans' offer. Could they be? Could they really give up their murderous rampage right here, at the very end, right when they had been on the verge of slaughtering the entire underground?

Then, to Sans' utter surprise, the knife fell from the child's grip, clattering onto the floor. The kid had actually spared him. This was amazing. "…. You're sparing me? Finally. Buddy. Pal. I know how hard it must be… to make that choice. To go back on everything you've worked up to. I want you to know… I won't let it go to waste… c'mere, pal." Sans stepped closer to the child. They had given up everything that had defined them. They had let go of the hate and the murder that had led them here, and with a drop of knife, let go of it. They had embraced Sans as a friend, looking for help.

It was too little, too late.

Sans struck, leaving the human no chance to evade at all. The soul of the human shattered, meaning that Sans had triumphed once again. "GEEETTTTTTTT DUNKED ON! If we're really friends, you won't come back." Sans said to the human, hoping to God that they would listen this time. Just stay away. Don't come back. Leave us alone.

Then everything faded away.
