The massive, heavily modified laboratory room was quiet, save for the low, constant hum of the industrial fume hood working in the corner. The bright, sterile LED lights overhead cast a sharp glow across the stainless steel workbenches, making the glass beakers and complex tubing sparkle.
Bellatrix stood at the front of the room, standing beside a large, pristine white dry-erase board she had rolled out from the corner. She held a thick black marker in one hand and a long wooden pointer stick in the other.
She turned to look at Max, who was sitting attentively on a tall metal stool, a fresh notebook resting on the table in front of him.
Bellatrix then officially started her lesson. She began by writing down a terrifying list of names on the board, her handwriting neat and incredibly precise. She wrote the headers for the compounds they were going to discuss: the theoretical components for a ricin bomb, a mustard gas bomb, a phosgene bomb, and the deployment of sarin and hydrogen cyanide.
She stepped back, surveying her grim list, and then raised her wooden stick, tapping it sharply against the hard surface of the board to command his attention.
"So, these are the primary components for the things that you said you need," Bellatrix said, her voice attempting to sound highly professional, though a sliver of dark humor leaked through. "Don't worry, Max. I will teach you the intricate theories of how to create these. And more importantly, I will teach you how not to accidentally kill yourself in the process."
Max looked at the names written in black ink. The sheer lethality of the list would make a seasoned military general sweat. Yet, the blonde woman in front of him was treating it like an advanced college seminar.
He offered her a serious nod, his amber eyes reflecting his deep gratitude. "Thanks, Bell. I appreciate it more than you know."
Bellatrix straightened her posture, taking her role as a teacher very seriously.
"So, first things first," Bellatrix began, pointing her stick toward a heavy metal cabinet near the emergency shower station. "Before we even touch a single beaker or handle a raw precursor, you deeply need to understand safety protocols. You need to wear your PPE—Personal Protective Equipment—at all times when the active synthesis begins. And you also need to prepare all secondary safety equipment in advance. That means positioning the fire extinguisher within arm's reach and having the chemical-burn medical kit fully prepped and open on the standby table."
Max picked up his pen and began to write diligently in his notebook, his handwriting sharp and angular. In his past life as an earthbound assassin, his 'safety equipment' usually consisted of a Kevlar vest, a backup weapon strapped to his ankle, and a clear exit route. This meticulous, sterile environment was an entirely new battlefield for him.
"Got it," Max replied, reading his notes aloud to confirm his understanding. "First things first, I need to wear my PPE without exception. And next, prepare all safety equipment like the fire extinguisher and the specialized medical kit before the operation starts. Is that all correct, Teacher Bell?"
Bellatrix nodded her head, a proud, approving smile crossing her face.
"Yeah, that's all correct," she praised him.
She turned back to the whiteboard, her demeanor shifting into intense focus.
"So, for the theoretical construction of the ricin-based deployment device…"
She paused, her eyes scanning the deep shelves of her locked cabinets. She walked over to a secure storage crate, rummaged around for a moment, and pulled out a heavy, sealed container and a few other securely wrapped items.
"Aha! Found it!" she cheered softly.
She walked back to Max's table and carefully placed the items down in front of him.
"To even begin the extraction process, you need specific raw materials," Bellatrix explained, pointing to the containers. "You need the raw castor beans, a highly specific industrial solvent—like a high-grade acetone or a lye solution at the very least—pure alcohol for the precipitation phase, and highly acidic water for the final purification."
She then reached under the workbench, unlocking a heavy, lead-lined safe. She pulled out a thick, rectangular block wrapped in dull green plastic, followed by a cylindrical object wrapped in brown paper. She placed them on the table right next to the beans with a heavy, ominous thud.
"And, to actually disperse the purified toxin effectively, you need volatile explosive materials. Something highly stable but powerful, like C-4 plastic explosives, or at least a military-grade stick of TNT!" Bellatrix said cheerfully, dusting off her hands. "Though, the only thing I currently have fully prepped and wired right now is this block of C-4."
Max stared at the green block of plastic explosive sitting casually next to his notebook. His amber eyes widened to the size of saucers. The air in his lungs vanished.
"Ho—how the hell did you get a fucking block of C-4?!" Max demanded, his voice cracking with sheer, unadulterated shock. "Isn't that highly illegal for a civilian to just have lying around in an apartment complex?!"
He was a master assassin. He knew exactly how hard it was to source genuine, untraceable C-4 in the modern world without alerting federal agencies. Yet this nerdy chemist had a block of it sitting in a safe under her desk next to her spare pens.
Bellatrix just laughed, a bright, musical sound that completely clashed with the deadly explosive on the table. She put a finger to her lips and winked.
"Secret~," Bellatrix teased in a sing-song voice. She then offered a surprisingly logical, if somewhat terrifying, explanation. "Also, a high-level chemist like me occasionally needs to prepare or study advanced energetic ingredients like this. Analyzing the rapid chemical reactions of making bombs and understanding explosive force are vital parts of our learning and scientific discoveries. You can't study extreme pressure reactions without the right tools!"
Max stared at her for a long moment. He slowly nodded his head, a deep sense of respect and lingering fear settling in his chest. He was slowly beginning to understand her. She wasn't just a nerd; she was a genius with a highly questionable moral compass when it came to scientific curiosity.
'Ahh, I see, I see….' Max thought inwardly, a small, dark smirk touching his lips. 'The mercenary was right. These brilliant scientists really do operate on a completely different wavelength. She is just as dangerous as I am, just in a different font.'
"So, getting back to the lesson," Bellatrix said, oblivious to his internal revelations. "The theoretical step-by-step process for extracting and weaponizing the compound is complex."
She turned to the board and uncapped her black marker.
She didn't write simple recipes. She began to draw intricate, highly complex molecular structures, linking hexagonal rings of carbon and detailing specific temperature thresholds required for the extraction phase. She explained the meticulous process of grinding the raw materials, the exact ratios needed to dissolve the powder into the harsh solvent, and the dangerous filtration methods required to remove solid impurities without contaminating the workspace.
Max watched her hand move rapidly across the white surface. He diligently copied her diagrams and notes into his book, his mind working in overdrive to understand the foreign concepts.
"So, that's the theory for step one," Bellatrix said, stepping back and capping her marker. "Do you have any questions so far, Max?"
Max looked down at his notes, then at the heavy mortar and pestle sitting on the counter nearby. He reached out and touched the heavy stone tool.
"None," Max replied smoothly. "Since most of the required theoretical equipment is already sitting right here in this room, and you have already shown me the raw materials, the process makes logical sense in my head."
Bellatrix let out a highly relieved sigh.
"I see, I see. That's really good," Bellatrix said, visibly relaxing. "At least you are not like those frustrating undergraduate students that I used to tutor when I first got here to this state."
She leaned against the whiteboard, crossing her arms.
"They used to ask so many incredibly basic questions," Bellatrix complained, her brow furrowing in annoyance. "I—I mean, asking questions is generally a good thing in science, but asking too many repetitive questions when the formulas are written right in front of them already tires me out. You actually pay attention."
She picked up her marker again, ready to continue. She stopped and looked over her shoulder at him one more time, just to be sure.
"You really have no questions, right?" she asked.
Max shook his head side to side. "None at all. Just keep writing, Bell. I'm following your logic."
Bellatrix smiled brightly at his confident response. She was genuinely glad he didn't constantly interrupt her flow. Teaching someone who grasped the lethal gravity of the subject matter was surprisingly refreshing.
She turned back to the board. "For step two…"
She began to detail the intense purification process. She drew out the diagrams for the precipitation phase, explaining the exact volume of alcohol required to force the toxic elements to separate from the filtered solution. She detailed the drying times, warning him of the extreme danger of airborne particles during this phase. Finally, she wrote out the equations for dissolving the dried, highly lethal material into acidic water to achieve maximum, terrifying purity.
Max diligently wrote every single step into his notebook, his hand cramping slightly from the speed of the lecture.
As he finished the last line of the purification phase, Bellatrix was already moving on, outlining the third and final step: the assembly.
She drew a rough schematic of a dispersal device. She explained the delicate, highly unstable process of mixing the purified, concentrated powder with an explosive material like the C-4 or the TNT. She detailed the physics of shaping the mixture into a durable bomb casing that could withstand handling but shatter perfectly upon detonation. Finally, she drew the wiring schematic for adding a reliable detonator to ensure a controlled, predictable explosion.
"And that covers the theoretical basics of the first agent," Bellatrix said, wiping a small smudge of dry-erase ink from her cheek.
She moved over to the next section of the board.
"Now, for the mustard gas deployment device, you need a different set of highly restricted ingredients…"
She walked over to a heavily secured, temperature-controlled cabinet. She pulled on thick, heavy rubber gloves before opening the door.
"You need sulfur dichloride, compressed ethylene gas, and an explosive dispersal material... like, oh look, another stick of TNT! Here, a fucking TNT stick!" Bellatrix said, her voice filled with dark, inappropriate cheerfulness as she carefully placed a heavy, red cylindrical stick of dynamite onto the reinforced table.
Max let out a long, heavy sigh. He just shook his head, choosing to completely ignore her terrifying excitement over high explosives. He focused his eyes downward, re-reading his detailed notes on the previous weapon to ensure he hadn't missed a single decimal point.
"And the theoretical step-by-step procedures for this one are incredibly delicate," Bellatrix warned, her tone shifting back to extreme seriousness. She grabbed an eraser and quickly cleared the first section of the board to make room.
She began to write rapidly, her marker squeaking against the board.
She detailed the perilous synthesis process. She drew a complex diagram of the fume hood setup, explaining the precise, terrifying chemistry of slowly bubbling the compressed ethylene gas through the highly volatile liquid sulfur dichloride at exact room temperature. She wrote out the resulting chemical equation, highlighting the production of the lethal sulfur mustard compound alongside the dangerous byproduct of hydrogen chloride gas. She emphatically circled the diagram of the cold trap, stressing that capturing the agent in freezing temperatures was the only way to prevent it from vaporizing and killing everyone in the room instantly.
She moved on to the purification phase, outlining the specialized distillation apparatus required to remove unstable impurities from the raw agent. She emphasized the critical need for perfectly sealed storage containers to prevent microscopic leaks.
Finally, she outlined the bomb assembly, drawing a new schematic for how to safely mix the liquid agent with the solid TNT to create a hybrid weapon that, upon violent detonation, would instantly vaporize and release the toxic gas over a wide area.
As she finished drawing the final wire on the detonator diagram, she lowered her marker and waited for Max to catch up. The sound of his pen scratching against the paper filled the quiet lab.
After a minute, she asked him, "Are you done writing those steps down?"
Max finished his sentence, placed his pen down, and nodded firmly.
"Yeah. I have it all committed to memory and paper. You can erase it now."
Bellatrix nodded, taking the eraser and clearing the board once again. The faint smell of chemical marker fluid hung heavily in the air.
"Alright, let's move on. For the next agent on your list, the ingredients required are entirely different…"
She walked over to a rack of heavy, pressurized metal cylinders standing in the corner of the room.
"…You need highly pressurized carbon monoxide, cylinders of pure chlorine gas, a highly specific activated carbon catalyst, and a reliable explosive material again, like another…. ughh, TNT!" she groaned playfully, lifting a heavy wooden box filled with more explosives and placing it heavily onto the workbench.
Max kept his head down, writing exactly what she said as he documented the volatile ingredients required for the third bomb on his list.
Bellatrix turned back to the clean board and started to write out the theoretical steps for synthesizing the third agent.
She drew a diagram of a highly specialized, heat-resistant fume hood setup. She explained the terrifying mathematics of passing equal, heavily measured volumes of the carbon monoxide and the chlorine gas directly over the activated carbon catalyst while maintaining a constant, extreme temperature of exactly 150 degrees Celsius. She wrote the resulting chemical formula, showing how the intense reaction produced the deadly phosgene compound alongside a massive, dangerous release of pure heat. She again highlighted the absolute necessity of a specialized cold trap to immediately capture the agent and prevent it from vaporizing into the atmosphere.
She quickly outlined the purification process, detailing the rigorous distillation required to stabilize the compound, and the terrifying reality of storing the purified, highly lethal liquid in hermetically sealed containers.
Finally, she drew the assembly schematic, showing how to integrate the liquid agent with the explosive charge to create a devastating, gas-dispersing weapon upon detonation.
She stepped back, resting her hands on her hips, and waited another five long minutes in silence as she let Max finish copying the dense, highly technical information.
The weight of what they were discussing hung heavy in the room. They were standing in a modern apartment building, calmly discussing the theoretical creation of weapons that had ravaged battlefields and caused untold nightmares in human history.
When Max finally placed his pen down, she asked him again if he was done writing. He offered a sharp nod. She quickly erased the board, leaving no trace of the horrific formulas behind.
"So, right now, since we are officially done covering the theoretical construction of the three explosive dispersal bombs," Bellatrix announced, clapping her hands together to break the heavy tension, "we should now start discussing the pure gaseous agents you wanted to learn how to make."
She picked up a fresh marker.
"The first one on your list is… Sarin," Bellatrix said, her voice dropping an octave, recognizing the sheer, terrifying infamy of the nerve agent. "And its primary required ingredients are highly restricted: methylphosphonyl difluoride, pure isopropyl alcohol, and sodium fluoride."
Max gripped his pen tightly, his amber eyes narrowing as he wrote down the names of the precursors. He knew that even attempting to buy those chemicals in bulk would flag him on a dozen federal watchlists.
Bellatrix turned to the board and began to write the step-by-step synthesis theory.
She drew a diagram of a heavily fortified fume hood. She detailed the incredibly dangerous, temperature-sensitive process of slowly, meticulously adding the isopropyl alcohol directly to the difluoride compound while maintaining a strict environment of exactly zero degrees Celsius. She explained the chemical role of adding a small, precise amount of the sodium fluoride to act as a reactive catalyst.
She wrote the final, terrifying equation on the board, showing the resulting nerve agent alongside the highly corrosive byproduct of hydrogen fluoride gas. Once again, she drew massive circles around the cold trap diagram, hammering home the point that failing to capture the agent correctly would result in instantaneous, agonizing death.
She outlined the purification phase, detailing the dangerous distillation process required to remove the corrosive impurities, and the extreme hazard of transferring the purified nerve agent into completely sealed, specialized containers.
Finally, she outlined the storage protocols. She detailed the grim reality of transferring the agent into airtight cans, heavy glass bottles, or reinforced flasks, emphasizing the absolute necessity of labeling the containers clearly to prevent a fatal, accidental exposure.
She stepped back and waited for another five tense minutes. The only sound in the room was the hum of the fume hood and the scratching of Max's pen.
When Max finally nodded his head to signal he was finished, she quickly and thoroughly erased the board, ensuring the horrific nerve agent formula was completely gone.
She turned to face him, leaning against the clean white surface.
"For the final agent on your list, Hydrogen Cyanide, the requirements are vastly different. It should primarily require sodium cyanide and highly concentrated sulfuric acid," Bellatrix explained, her tone shifting slightly.
She turned and began to write the final theoretical step-by-step process on the board.
She drew the fume hood setup one last time. She detailed the highly dangerous, yet terrifyingly simple process of slowly adding the heavy sulfuric acid directly to the sodium cyanide at standard room temperature. She wrote the resulting equation, showing the rapid, violent production of the lethal hydrogen cyanide gas and the solid sodium sulfate byproduct. She drew the cold trap one final time, illustrating how to capture the deadly gas before it filled the laboratory.
She quickly outlined the purification distillation, and the highly specific storage protocols required to keep the purified agent stable in airtight, pressurized flasks.
Bellatrix finally placed the cap back onto her black marker with a sharp click. She placed the marker and the wooden pointer stick down onto the workbench.
She turned around, leaned her hips against the edge of the heavy table, and looked directly at Max.
"So…" Bellatrix started, a challenging spark returning to her bright gray eyes.
"…After covering all of that intense theory, what do you wanna actually learn how to execute first?" she asked him.
Max didn't answer immediately. He sat on the metal stool, staring down at the pages of his notebook. His mind, honed by millions of regressions and countless assassinations, rapidly analyzed the vast amount of highly technical data she had just given him.
He analyzed the tactical viability of each weapon. The ricin required days of extraction and drying. The mustard gas required complex bubbling procedures and highly unstable precursors. The phosgene required extreme, sustained heat that could easily be tracked by thermal imaging. The sarin required freezing temperatures and catalysts that were nearly impossible to source quickly.
He needed something fast. He needed something reliable. He needed a weapon he could theoretically construct in this very room within a matter of hours if the green-eyed stalker decided to breach his front door tonight.
Max closed his notebook with a soft thud. He looked up, his amber eyes locking onto hers with cold, absolute certainty.
"It should be the easiest one," Max said, his voice smooth and decisive.
Bellatrix slowly nodded her head as she heard his calculated response. A small, impressed smile touched her lips. She understood his tactical logic perfectly.
"All right, all right. Hydrogen cyanide it is, then," Bellatrix confirmed, crossing her arms and nodding in approval.
She pushed herself off the table, her scientific energy returning in full force.
"It is a highly logical choice for a rapid defensive measure. Well, theoretically, it only needs two primary materials to initiate the reaction. It has the absolute minimum equipment requirements out of everything on your list. It yields a terrifyingly fast chemical reaction, and lastly, the synthesis process is incredibly low-tech compared to the nerve agents."
Max nodded his head, confirming his choice.
"That one, then," Max replied, his muscles tensing slightly in anticipation. "Should we start the practical application now?"
Bellatrix slammed her hands down flat onto the thick epoxy surface of the workbench. Her gray eyes shined with the thrilling, highly dangerous excitement of a genius about to push the boundaries of her science.
She looked at the legendary assassin sitting in her laboratory and offered him a brilliant, slightly unhinged smile.
"Sure!" Bellatrix replied enthusiastically.
