Chapter Text
The Surgical and Critical Care Wing on the upper floors of the North Tower was a realm governed by absolute logic, high-pressure sterility, and unyielding silence. Here, the thin line between life and death was measured in precise surgical incisions and the steady, rhythmic bleeps of intensive care monitors. It was a place where human emotion was often treated as an unnecessary complication—a philosophy personified perfectly by Dr. Beelzebub.
As the Chief of Thoracic and Transplant Surgery, Beelzebub was a permanent fixture of the North Tower’s bleakest hours. The hospital staff called him the "Grim Reaper," a moniker earned not just from his dark, heavy eyebags and perpetually somber demeanor, but because the cases transferred to his hands were almost always teetering on the edge of the abyss. He dealt with crushed chests, failing lungs, and hearts that refused to beat on their own. To Beelzebub, the hospital was a machine, and he was merely the mechanic keeping the gears from grinding to a final, permanent halt.
He preferred the quiet. He preferred the sterile, predictable nature of his routine.
Which was exactly why his current existence felt like a direct violation of his mental sanity.
"According to basic acoustic physics, Chief, the auditory alert system of these standard-issue ICU monitors is fundamentally flawed!"
Beelzebub didn’t look up from the patient chart he was reviewing at the central desk, but his grip on his sleek black pen tightened until his knuckles turned white.
"Dr. Tesla," Beelzebub said, his voice dropping to a dangerously low, gravelly octave. "You have been a first-year cardiothoracic resident under my supervision for exactly four days. In those four days, you have managed to speak more words than I have uttered in the past four fiscal years. Be quiet."
"But I am speaking the absolute truth!" Nikola Tesla beamed, completely immune to the lethal aura radiating from his superior.
Nikola was a stark, jarring contrast to the gloom of the North Tower. While Beelzebub looked as though he lived on black coffee and existential dread—his messy black hair framing a pale face marked by dark, heavy eyebags and deep, murky brown eyes—Nikola practically vibrated with an erratic, brilliant energy. The first-year resident stood a few inches taller than his Chief, a lean and imposing figure topped with a wild mane of curly brown hair. His eyes, a pair of shockingly bright blue spheres, held a vivid, childlike wonder that felt entirely out of place in a ward full of failing organs.
Worse yet, Nikola was currently sitting cross-legged on the tiled floor right next to a highly sensitive, state-of-the-art ventilator setup, holding a miniature precision screwdriver he had somehow smuggled past hospital security.
"Look at this objectively, Dr. Beelzebub," Nikola continued with soaring enthusiasm, gesturing wildly with his screwdriver. "The current alarm emits a high-pitched, discordant 800-hertz frequency whenever a patient’s oxygen saturation drops. While it successfully alerts the nursing staff, it also induces unnecessary sympathetic nervous system arousal in the surrounding patients! It elevates cortisol, spikes blood pressure, and disrupts the natural healing frequencies of the human body!"
"Nikola," Beelzebub hissed, finally closing the chart with a sharp, echoing snap. "Put the screwdriver away and step away from the multi-million-dollar medical equipment before I have security throw you out of the tower."
"I am merely optimizing it!" Nikola countered, standing up and brushing off his trousers with a triumphant grin. "If we modulate the acoustic output to match a harmonic minor scale, the alarm will still catch the human ear effectively, but it will do so without causing a cascade of biological panic. Science, Chief, should always serve to harmonize humanity with the laws of nature!"
"Science in this department involves following established clinical protocols, not playing garage mechanic with life-support systems," Beelzebub said coldly, rising from his chair to loom over the resident. "Your job today was to update the post-operative fluid balance sheets for Bed 4 through 12. Why are you not doing that?"
Nikola waved a hand dismissively. "Oh, those? I finished them three hours ago. I even took the liberty of restructuring the data entry format. The previous layout was terribly inefficient and lacked geometric symmetry. I created a new algorithmic template that cross-references their metabolic rates automatically. It will save the residents at least forty-five minutes per shift!"
Beelzebub blinked. He stared at the younger doctor, trying to find a trace of deceit, but Nikola’s expression was entirely earnest, practically begging for scientific validation.
Silently, Beelzebub pulled up the ward’s digital system on his tablet. Sure enough, the patient logs were completely updated. Not only were they done, but the formatting was impeccably organized, using a clean, highly efficient macro system that Beelzebub had to admit—grudgingly, in the deepest, darkest corners of his mind—was brilliant.
Beelzebub stared at the glowing screen, his sharp eyes tracking the lines of code. It wasn't just neat; it was a flawless mathematical compression of raw clinical data. Every metabolic rate, every fluid fluctuation, and every cross-reference was locked into a beautiful, geometric symmetry. For a surgeon who spent his life fighting the messy, unpredictable decay of human flesh, seeing such absolute, unyielding order on a screen was hypnotic.
"The standard hospital software utilizes a linear sequence, which causes a processing lag when multiple critical care beds update simultaneously," Nikola explained, his tone dropping its booming bravado for a split second, replaced by the pure, earnest devotion of a scholar. He stepped closer, pointing a long, gloved finger at a specific macro cell. "But by converting the data entry into a multi-layered matrix based on thermodynamic equilibrium formulas, the system processes the variables simultaneously. No lag. No wasted seconds."
Beelzebub didn't say a word. He couldn't.
For the past four days, he had written Nikola off as an eccentric, loud-mouthed nuisance who had somehow stumbled his way into a residency program. He had expected a chaotic mind, but looking at this template, he realized Nikola’s mind wasn’t chaotic at all. It operated on a level of structure so advanced, so intensely organized, that it bordered on terrifying. The kid wasn't just playing with formulas; he was trying to force the rigid, uninspired bureaucracy of modern medicine to bend to the elegant laws of the universe.
Grudgingly, Beelzebub felt the icy wall of his skepticism crack, just a fraction. He closed his eyes for a brief moment, letting out a silent, defeated breath. God help them all, the boy was a menace to the hospital’s IT department, but he was an absolute, undeniable genius.
"See?" Nikola leaned over Beelzebub’s shoulder, entirely disregarding the concept of personal space. A faint scent of ozone and mint tea wafted over the older doctor. "Invention is the peak of human expression! We must never settle for the mundane when perfection is well within our mathematical grasp!"
Beelzebub stepped sideways, putting a deliberate two feet of distance between them. "Your unauthorized alteration of hospital software is a bureaucratic nightmare waiting to happen. If Dr. Poseidon sees a single unauthorized macro on his cardiac wing reports, he will file a formal complaint with the board before sunset."
"Ah, the Chief of Adult Cardiac Surgery does possess a rather... rigid adherence to standard operating procedures," Nikola mused, rubbing his chin thoughtfully. "But fear not! I shall simply explain the fluid dynamics of my new formatting to him tomorrow. I am sure he will appreciate the mathematical elegance."
'He won't. He will literally try to suspend you,' Beelzebub thought, pinching the bridge of his nose as a migraine began to bloom behind his eyes.
"Go assist the nurses with the evening rounds, Nikola," Beelzebub ordered, his tone flat and unyielding. "And if I catch you with a screwdriver near the ICU monitors again, I will personally reassign you to the basement archives to sort historical autopsy files for the rest of the semester."
Nikola’s eyes lit up, completely missing the threat. "The historical autopsy archives? Fascinating! The genetic mutation data from the early twentieth century must be an absolute goldmine of cellular anomalies! Do you think Dr. Simo would let me look at the tissue samples? "
"Out," Beelzebub deadpanned.
"Right away, Chief!" Nikola gave a cheerful, overly dramatic salute, spinning on his heel. His lab coat flared out behind him like a cape as he marched down the corridor, already loudly greeting a passing nurse with an enthusiastic lecture on the thermal conductivity of the hospital’s new blankets.
The ICU fell back into its familiar, quiet rhythm, the standard 800-hertz alarms bleeping intermittently in the distance.
Beelzebub exhaled a long, heavy breath and sank back into his chair. He looked down at his tablet, staring at the perfectly coded, hyper-efficient patient charts Nikola had left behind. For a man who lived in a world where everything eventually decayed and died, Nikola’s sheer, unadulterated vitality was exhausting. The resident was too loud, too bright, and entirely too chaotic for a sterile environment.
And yet, as Beelzebub's eyes scanned the flawless mathematical logic of the new chart layout, a microscopic, almost imperceptible twitch tugged at the corner of his lips.
The kid was an absolute public nuisance. But God help them all, he was a genius.
