- A/N -

Hello folks, long time no see. Sorry for the delay, I've gotten a bit short on time to write (which is honestly due to my poor planning), and a bit of writers block.
Not entirely sure if this chapter is really necessary but I think it provides a good view on a part of Sans situation.
If I may ask, what do you guys think of the story and the chars so far?

- A/N End -

The fight with the human had been long but it had inevitably come to a end. Now the human was just a vague lump of limps sprawled on the ground while the knight was still standing tall. But the armoured monster seemed quite shaken although the human hadn't even hit them once. What is with her? Looking closer at the scene displayed on her monitor the relief of the observing monster about the end of the fight changed into concern as the knight turned sharply away from the human. Yellow scaled fingers making some quick key strokes the scene on the large monitor changed to another viewpoint showing again the front of the knight.

Upper body slightly trembling the armoured monster clenched her fists and looked down as would she try to focus on something. This lasted for a moment or two bringing the observing monster on edge as she switched rapidly from camera to camera to determine what was wrong without seeing any visible mark of a human attack. Having zoomed in to get a closer look silently cursing the quality of the images the observing monster almost missed when the knight moved again. Removing one of her gauntlets the knight pulled a mobile phone from her metallic sleeve to fiercely type a short message.

Huh? What does the phone there? Hitting some more keys on the keyboard before her the observing monster opened a smaller window with a paused image of the knight's sleeve. This space was not designed to hold something! Creasing her yellow scaled forehead the observing monster inspected the image with annoyance about the misused equipment. However this emotion was quickly forgotten as ingenious thoughts filled the monster's head. But at the same time it is true that the armour has no means of communication… Absently nibbling at her talon like nails the observing monster pondered about the possibilities. I could add something to the helmet... Remembering something the monster shook her head dismissively. Or at least a real docking station in the sleeve..., her gaze went back to the knight on screen eyes widening in sudden insight, with muscle powered charging! The monster's short snout displayed a happy grin. She'll love that! Noting the coin-sized molten spot on the knight's temple the observing monster concluded with a bit of guilt. The armour needs a overhaul anyway after that other monster damaged it. Having no footage of this fight the yellow monster took a silent note to install more cameras in waterfall. The plans should be in the top drawer... Already pondering about the update for the armour the observing monster turned her revolving chair around and stood up without giving the half-lit room a second look. Just to come face to face with another monster that must've entered the room silently when she was distracted with the knight.

Head glowing ghostly white in the diffuse light of the large monitor the unexpected visitor cast the yellow scaled monster a pally smile. "hey doc."

Letting out a scared shriek the yellow scaled monster almost toppled the chair as she recoiled and fell back into it. Recollecting her breath the yellow scaled monster's voice was a bit shaky as she asked, "P-p-p-please stop doing that."

Absently shrugging of her demand the visitor stepped closer to the desk and the large screen. Watching the knight typing again the visitor asked with causally interest, "did you record the fight?"

"O-o-of course," entering a few commands the yellow scaled monster divided the large monitor in multiple windows each replaying different scenes from the fight, "it is all here."

"i see..." Moving from left to right the two white dots representing the visitor's eyes jumped quickly from window to window. "interesting..."

Waiting a few moments for her visitors to take it all in the yellow scaled monster asked hesitantly, "Do you know what they were doing?" Finishing another loop the scenes on the monitor started again after the recorded image of the human was once more struck down by a green spear. "This doesn't really looked like a typical fight."

"who knows? humans can be strange sometimes...-" Answering halfhearted the visitor peeked up as another window accompanied by a repeating unnerving beeping pooped up overlaying the data from the fight. "huh? what's that?"

Straightening up on the beeps of alarm and the yellow-stripped black border of the window the yellow scaled monster needed just a short look at the title to identify it. "T-that is the souls monitoring," looking closer the irritation about the appearance of the alert changed into distressing alarm as she noted the data it was displaying, "Its all off the charts…!" Jumping up impulsively the yellow monster toppled the chair this time as she hurried to the door, "I n-n-need to check that!"

Rushing through half-lit floors the yellow scaled monster passed multiple doors that looked all the same to the uninitiated eye until she reached the room where the souls were kept. This door too was just an ensemble of plain plastic setting itself only through a more greyish colour from the walls apart. Hasty bashing a code into the keypad besides it the yellow monster squinted as the door hissed open and her unadjusted eyes where met with bright light flickering in bursts of light blue, blue, orange, purple, green and yellow through the room. Covering her eyes with her white sleeve the monster quickly went to one of the terminals at the base of the six glass cylinders that were emitting the light in unsteady rhythms and intensity. Dismissing the same warning she had seen just a minute before the yellow monster entered single-handed two short commands into the terminal, 'filters activate; sensors report all'

Following her first command the room darkened abruptly as the walls of the cylinders dimmed the light down to acceptable levels. Lowering her arm the yellow monster's relieved eyes flew over the data displayed in the new window on the terminal her second command had opened. The window was divided into six segments each one indicating the cylinder their data was coming from with a specific colour. Light blue, blue, orange, purple, green and yellow... all of them are active! Assessing the segments the yellow monster panicked as her knowledge and intellect failed to determine what was going on. This souls are broken! There should be no consciousness left to stimulate the pieces! Relaxing from panic crawled hands the monster tried to pull herself back together. Breath! Calm down! There has to be an explanation. Reaching for the keyboard the monster initiated another command, 'sensors deep-scan all' At least there is always one in the Anim-

Having focused entirely onto the terminal the yellow monster was startled the second time by her visitor as he suddenly asked from behind. "sup?" Jumping on the unexpected pally voice in her ear the yellow monster in the lab coat almost chocked on her own breath as she answered. "S-s-s-something is stimulating the souls to emit irregularly bursts of energy and light," forcing an optimistic smile on her snout to ease the situation the monster added, "B-b-but this may be actual a good thing if we can figure out how to use the souls energy without fusing them to a monster."

Studying the growing bars on the terminal screen indicating the scanning progress the visitor nodded remarking causally, "ah so you could say that this could enlighten us?"

"Perhaps I mean the old books hold a lot of knowledge but-," noting the rather obvious stress on the word with delay the excitement in the yellow monster's voice changed to embarrassment, "O-oh that was a joke?"

Shrugging the visitor replied with a wide grin, "well it's not a light thing to ignore such a possibility."

Racking her brain for a proper reaction or answer to this the yellow monster was saved from the awkward moment as the scanning processes ended with a electronic beep. "O-oh Its finished," nervously passing over her visitors jokes the monster hit another set of keys to display the scan results. Gazing over the displayed numbers the yellow monster stopped short as she spotted something strange. Pointing onto it she turned to her visitor, "Do you see that too?"

Stepping closer the visitor took a short look at the string of numbers the yellow monster had pointed out. Glancing over the results the visitor noted seemingly bored, "six different energy patterns from six different souls and...", trailing of he frowned, "one common sub-pattern?"

Flaring up like a strip of broken fairy lights each of the cylinders plunged the room for a brief moment into their representative colour as their blazing contents outpaced the filters for a moment.

The yellow monster nodded. "Yes and it is stimulating them", turning towards the keyboard she entered another set of commands, "here look!" Reacting to the monster's inputs the data on the terminal was replaced by six monochrome cross-sections showing the insides of the cylinders. The remains of the souls were displayed as pale white dots of varying size drifting aimlessly around while the rest of the cross-sections were filled with erratically static patterns representing surplus energy emitting from the pieces. One of the smaller fragments in one of the cross-sections flared up to a bright white emitting a wave of static that swept over the other fragments letting them flare up as well while the corresponding cylinder erupted with another burst of blue light that was just barely dimmed by the filters.

White dot-eyes wandering from cross-section to cross-section the visitor watched as other waves of energy erupted erratically without a specific pattern or system in the other cylinders. "hmm..." Watching another wave he put a finger down on the screen marking the triggering fragment with its tip. The yellow monster flinched as he touched the glass but didn't say anything. Finger following the small fragment the visitor watched as another wave swept through the cross-section. He waited. Another wave lit up the screen. He waited again. Watching the next wave he heard the yellow monster inhale sharply mumbling, "Every wave… It's starting every time at the same fragment..."

Again the filters where outpaced as another heavy surge lit the cylinders up filling the room once more for a moment with blinding multicoloured light as the erratic flickering seemed to stabilize before plunging back into chaos.

"I wonder if…," yellow scaled fingers flying over the keyboard the scene on the terminal changed slightly as a tiny null appeared besides every fragment. Fully absorbed by her deliberations the yellow monster watched on edge as another wave swept through one cross-section and the tiny number besides the triggering fragment changed to a one. Then to a two on the next quickly followed by a three and so on while the numbers of the other fragments in the cross-section stayed persistently at zero. Looking at the other sections the yellow monster felt exiting confirmation as it was the same with them one fragment triggering every wave while the others remained passive. "This is new! The books say nothing about this!," voice going up in excitement the monster started a new analysis comparing the triggering fragments to each other and every magically phenomenon known to her databases.

Pursuing his one interpretations and thoughts about the phenomenon the visitor nodded just absently at the yellow scaled monsters remarks. Tilting his head he stared at the cylinders white dot eyes peering for a moment to a empty one at the wall. A short frown wandered over his face as he pondered about something or someone. Turning abruptly his back to the cylinder the visitor seemed to want to shake this though of.

Flaring up simultaneously the cylinders filled the room with their multicoloured light as the filters finally surrendered. Casting their shine now without restraint the light from the cylinders reached within split seconds utterly blinding intensity. Reducing the sensitivity of his eyes the visitor remained calmly standing while the yellow monster squealed yanking her arms in instinct before her face. Reacting as well to the energy eruption the terminal sounded a distressed alarm displaying a warning that was just barely visible to the visitor's eyes before the inferno of light.

"i think we should leave now." Showing not much concern the visitor grabbed one of the yellow monster's arms. Shuffling towards the door the blinded monster in tow the visitor perceived a faint humming of power. interesting... there is still more energy building up. Moving intuitively faster as this thought crossed him the visitor reached for the door controls. Hitting a button he cast a causally sideglance towards the yellow scaled monster as the door hissed open. Still holding her arm he wondered genuinely if the bright light from the souls could damage her eyes in the same way as normal light would. well there would be a way to find out... Pondering about this interesting puzzle the visitor directed the yellow monster out of the room into the much darker corridor.

Crimson light exploded in the room behind the two monsters followed by the sound of popping glass. A hot wave of solid air washed over them before the door could close. Eyes adjusting just slowly after the overly bright room the visitor didn't see much of the poorly lit floor. Dusting of his blue sweater the visitor remarked in the pally voice of his,"well doc that lab might be trash but at least you can say it was an enlightening experience."

A familiar booming voice answered the visitor, "SANS STOP DREAMING! WE'VE TO KEEP MOVING OR WE WILL LOSE TORIEL AND THEN I CAN'T HELP A LADY IN NEED AND THEN UNDYENE WILL NOT BE IMPRESSED AND THEN SHE WON'T MAKE ME A ROYAL GUARD!"

Hearing his brother's rant Sans's body stiffened as his mind went into denial. that's impossible it can't be. Adjusting to the poor light Sans's eyes were greeted by the metallic walls of a tunnel. He remembered this place. Papyrus had followed Toriel in her after he had jumped of the wooden bridge. Feeling now as well the cold water at his feet the denial curled itself into a small knot of shock. no. no! this cannot be! Gaze flickering over the walls Sans noted the illuminated opening of an intersecting tunnel. Focusing onto it he got a last glimpse of Toriel's purple dress as she rounded a corner. Realizing the truth his hands trembled. it can't be! i've seen it! the knight killed them for good! there is just no possibility how they should've managed to do another one not after so much time has passed since-

Interrupting his brother Papyrus placed a bony hand on Sans forehead, "SANS? ARE YOU FEELING ALRIGHT?" Dot-eyes looking into dot-eyes Sans saw genuine concern in his brother's face.

"yes yes" Calming himself Sans switched back to his usual pally behaviour. There was no time for panic now. "I've just to go check something." Reaching up Sans removed causally Papyrus hand from his skull.

"SANS-!" A large false grin hiding his true state of mind Sans ignored his brother's protest already picturing his destination beneath waterfalls eternal night. And then he was gone.
