MEMORYTALE --- Your Best Friend (Undertale AU)

Snas is getting nervous and thinks of past events

Real chapter name which is too big: 

Sans is getting nervous and has a good reason. Also, Sand Memoryeetable thinks of past events.

Sans was scared.

The deja vu was gone for the first time in a while. The deja vu was a part of his life now, that feeling that he knew what happened next was basically embedded in his SOUL. And one day, he woke up, and it was gone. That was yesterday.

It was never gone.

Usually, there were times where he could feel the sense, he knew what happened next, he could, well, feel it in his bones. He always tried to dismiss this as reading people's expressions, but even he couldn't admit it was creepy sometimes. Even his own brother didn't have this deja vu to the extent of his.

Well, that was to be expected with his 'condition'.

The short skeleton though out what he could do today. Papyrus was out training with Undyne or getting the puzzles ready which left two things.

1. Absolutely nothing (right answer)

2. Something productive

As much as Sans wanted to pick the first option, he decided he needed to go to the lab anyways.

Good thing he knew a shortcut.

"heya alphys," Sans said, entering the lab. Alphys was staring at some monitors, "what'cha doing?" The lizard monster quickly minimized something on the giant monitor looked at Sans.

"Oh, um... N-nothing!" She stuttered out. Sans started slowly clapping.

"and the best lier of the year award goes to," Sans said, giving Alphys a look.

"Okay, f-fine. I was w-wondering h-how Mew Mew K-kissy Cutie would look on t-this big screen," Alphys said, pointing at the monitor that she was supposed to be looking out for any threats, like humans.

"ok, if you say so," Sans said. The skeleton shrugged. Alphys sighed.

"I-if you are h-here anyways, I n-need to talk t-to you," She said, looking into Sans' eye sockets. Sans found no reason not to let her.

"why not?" The skeleton responded, curious about what Alphys wanted with him.

"W-well, I was looking at the security camera," Alphys started, Sans started laughing a bit. Alphys glared at him, and he quickly shut up.

"N-now you know, I d-do have s-spots without cameras, like that room in the back of your house and the Ruins. A-anyway so, I saw this frame in the footage," Alphys pointed at a frame showing Sans leaving the back room. Sans immediately tensed up but tried not to show it. It seemed that he didn't want Alphys to see that frame.

"i knew that was a bad idea," he thought to himself.

"S-so, I was curious about what you were doing so early in the morning, so I zoomed in. And I saw this," Alphys said. Sans decided that he should take his leave now, but Alphys holding his arm prevented that. He could take off his coat, but then he would have to come back and get it. But Sans was curious, he wanted to know how much Alphys knew. Alphys proceeded to zoom in on the garbage can. Some red liquid was seeping out.

"expired ketchup," Sans lied, with a shrug.

"What?" Alphys exclaimed, dumbfounded.

"expired ketchup, that's what's in the can,"

"Sans, you and I both know whats you've been getting rid of,"

"right, ketchup,"

"Sans no," Alphys said, with a sigh.

"anyways i have something to do," Sans started.

"Don't even try to change the topic on me," Alphys said. Sans was surprised how little she stuttered when talking about anything remotely related to her passions, which sadly involved anime.

"fine. what if your right. at least i'm getting rid of it, not, you know... injecting it," Sans said.

"Y-your right but how do you even have any of that?"

"i..." The skeleton started, not knowing how to explain, "i have my ways. listen alph, both of us have secrets, and i respect that, i don't poke into yours, you don't poke into mine, got it?"

"F-fine," Alphys said with a sigh.

"anyways, i wasn't lying about needing to do something here, and i know what i'm doing, so if i could just dismiss this conversation?"

"Fine, but I got my eyes on you,"

"and i got my eye, er eye-sockets on you," Sans said with a wink.

The skeleton took his leave and went to find the needles. They might come in handy quite soon.

Once Sans got the essentials from the lab, he was back at his home in snowdin. He would normally be at the door to the Ruins talking to the nice door lady, but she wasn't there, he knew it had something to do with the kid with the dusty hands. The human.

He was curious about what type of human this one will be. She seemed to act like the third one, the integrity SOUL. Killing just for the fun of it, but the new one seemed harder to stop. It was lucky that he wasn't a pile of dust. But this new one seemed more, hesitant. She would only kill if the monster provoked them, but would also try to get the monster's attention.

Sans would need no margin of error if he needed to fight. This kid was dangerous. And he needed to keep his brother safe. That might be a bit of a challenge, with him wanting to be a part of the Royal Guard. Integrity SOUL at least came 'round when Papyrus was still a baby-bones, and couldn't do anything about it. It was some time where everyone would just stay inside and hope she wouldn't find them.

Yes, she had a name. She didn't deserve one though. Most of the Monsters referred to the kids as their SOUL colours, as they didn't think most of them deserved a name.

Only two of them never tried to kill, only two of the human's names were remembered. Sans found it more important to know the names of his enemies. He had higher stats back then, and he weakened Integrity down a bit. If he kept going, he knew he was going to die.

Humans. That brought Sans back a long way.

Sans wouldn't say he knew The first human. Chara. But that was a lie. Most monsters knew how close they were. Sans and Chara were the definitions of prank masters, once playing a prank on the old owner of this home even. And he was a respectable man, but Chara dragged Sans and his adopted brother Asriel into it. Chara always dragged Asriel into it, but would always bail the two of them out. Usually with strange methods. There were still places on the floor and walls bleached out that Sans didn't feel like replacing. Of course, the TV was on top of it, and no one could see it, but it still held memories for Sans.

Memories he would hate to forget.

And even if Chara and Asriel were dead, he still couldn't help but think about them.

But sometimes, you have bigger issues on your plate, for example; how to hide all of the needles from Papyrus and make sure they don't end up in the trash tornado. Or getting prank called and turning the tables on them. Yea, he knew something was up with 'Cameron'.

But everything was only a matter of time.

OwO. I was getting tired of Chara and Frisk. Plus Sans has a very interesting backstory. Ooh, and the other humans make a mention. Guess which humans gained no LV!

if you want of course

Also- this takes place during last chapter. 

Same time, just different point a view.
