Passive Hatred

The Lab

=================

Alphys stood over Alex's unconscious form, her hands trembling as she adjusted her glasses. The soft glow of the lab's monitors illuminated the room. She had examined many monsters and even traces of human souls, but this was something very different.

She pulled over a hand-held machine with a softly glowing panel, adjusting the dials nervously. This scanner would measure Alex's magical output, a standard procedure for analyzing monsters. With a hesitant breath, she began the scan.

As the machine started its low hum, Alphys watched the monitor carefully. At first, the readings seemed normal—low energy output, stable condition. But then, the machine began to spike. The magical energy it detected fluctuated wildly, jumping between almost non-existent to an overwhelming surge. Alphys's eyes widened. "W-What...?"

Suddenly, the machine crackled, and a jolt of magic surged through the cables. Alphys jumped back as the monitor flickered and shut down, smoke rising from the back of the equipment. She stared at the fried machine.

"W-What kind of magic is this?" she whispered to herself.

With her primary scanner now ruined, Alphys turned to a backup device—one designed to measure soul structure. She connected the leads to Alex, careful not to disturb him. If his magic was this unstable, maybe his soul would give her more answers.

She activated the soul scanner, watching as it projected a soft light over Alex's chest. A few moments passed before an image formed on the screen. Alphys blinked, her heart momentaraly forgot how to beat.

Instead of the familiar heart-shaped form she expected from human or monster souls, Alex's soul was... irregular. Its shape was not the neat, symmetrical heart of a human, nor the inverted heart of a monster. It was distorted, jagged, like it was torn or incomplete. It pulsed with a dark, inky aura, and strange tendrils of energy seemed to coil around it, like they were alive.

Alphys stared, her mind racing. She had never seen anything like it. "This... this isn't right," she muttered. "What are you...?"

The soul flickered suddenly, and for a brief moment, it lashed out—dark tendrils of energy spiking from the image, crackling against the monitor. Alphys stumbled backward, clutching her chest. The machine short-circuited, the lights dimming for a second before stabilizing.

Taking a deep breath, she steadied herself. The power Alex's soul held was unstable. It wasn't just the appearance that was abnormal; his soul seemed to be constantly fighting, shifting between states of calm and chaos. But why? What had caused this?

She pulled out her clipboard, scribbling down notes as quickly as her shaking hands would allow. "Unstable soul structure... non-standard form... fluctuating magic output," she murmured to herself. "This is unlike anything I've ever encountered."

She scribbled down notes in her shaky handwriting, her mind whirling with theories.

"Maybe... maybe he's some kind of hybrid?" she muttered to herself, glancing back at the jagged, irregular shape of Alex's soul on the screen. It pulsed erratically, tendrils of dark energy swirling around it like shadows. "I mean, we've never seen a human-monster hybrid before... right? But if he was part human, his soul should still be heart-shaped. This... this is something else."

Alphys tapped the side of the monitor, hoping for clearer readings, but the data remained inconsistent. She bit her lip, her mind racing . "Could he have been... exposed to some kind of magic experiment? I've seen unstable soul reactions in the lab before... but nothing like this." She paused, remembering her earlier work on Determination and how it affected souls. "But that wouldn't explain the shape... or the tendrils. The magic is just so... wild."

Her fingers drummed nervously on the side of her clipboard as she considered another theory. "What if... what if he's not from here at all?" she whispered, eyes widening. "He could be some kind of creature from another dimension or timeline... a place where the rules of souls are different?" The thought of alternate timelines made her shudder slightly, recalling the  consequences that messing with time could bring.

She jotted down a note: Possible origin from a parallel world? Unfamiliar soul structure.

Looking back at the readings, Alphys noticed how the dark tendrils pulsed with each irregular beat of his soul. "What if... his soul is cursed?" she said, her voice shaky. "There are legends about ancient soul curses... but they're just myths, right? Or maybe he was hit by some kind of forbidden magic that changed his soul's very nature."

She flipped through an old book of magic lore on her desk, scanning for any mention of cursed souls or mutations. Her heart raced as she thought of the implications. Could Alex have been exposed to some dark, forbidden force? Something so powerful, it reshaped his very being?

"But then again..." Alphys trailed off, glancing at the flickering monitor, "what if he's not... alive at all? Maybe his soul is artificial, created by magic or science." She shuddered at the thought. She'd heard rumors of such experiments, but none had ever succeeded. Could Alex be the result of such an experiment? If so, who created him—and why?

Her hand trembled as she wrote: Artificial soul? Experiment gone wrong?

She stared at Alex for a long moment, watching his chest rise and fall with shallow breaths. His soul was so different, so wrong in ways she couldn't fully understand yet. "What are you?" she whispered again, feeling the weight of the mystery hanging over her. There were too many questions and not nearly enough answers.

With a deep sigh, she leaned back in her chair, staring at the ceiling. She could spend weeks, months, even years trying to figure out what Alex truly was. But for now, she had to focus on the facts. His soul was unstable, his magic unpredictable. Whatever had happened to him, he was a danger not only to himself but potentially to everyone around him.

She closed her notebook, staring at the dimly glowing tendrils flickering on the monitor screen. "I just hope we can figure this out before it's too late."
