"Again," he called as Cox executed another perfect takedown. "And this time, anticipate the counter before it happens."

  Larissa rose immediately, her determination undiminished by repeated failure. Whatever she had been before, be it slave, victim, or survivor, she was being systematically replaced by something new: soldier.

  The midday bell echoed through Fort DC's training grounds, signaling the standard lunch break for all non-essential personnel. Kevin led Cox and Larissa to a quiet corner of the chamber, away from the main clusters of soldiers heading toward the mess hall. Their secluded position against the concrete wall offered a partial buffer from curious stares while providing a clear sightline to all entrances, a habit from years of soldiering that Kevin maintained without conscious thought. He retrieved three standard-issue protein bars and water rations from his cargo pocket, distributing them with the economy of movement that characterized everything he did.

  "Not exactly gourmet," Cox remarked, tearing open her protein bar's wrapper with a sharp canine. "But it beats field rations." She settled cross-legged on the ground, her tail curling around her hip as she took a bite of the dense, brown rectangle.

  Larissa examined her protein bar with cautious curiosity before mimicking Cox's movements. Her first bite was tentative, followed by a look of mild surprise. "It's... sweet," she observed.

  "Artificial honey compound," Kevin explained, unwrapping his own ration. "Calorie-dense nutrition engineered to optimize physical performance." He ate methodically, his enhanced metabolism processing the nutrients with remarkable efficiency. The red bar in his vision remained at nearly full capacity despite the morning's exertions.

  Cox finished her bar in four quick bites, then rose to her feet with a stretch. "I'm due for weapons maintenance at 1300," she said, checking her watch. "I'll catch up with you two before dinner bell." Her ears twitched in Larissa's direction. "Not bad for your first session, Red. Tomorrow we'll work on your ground game."

  When Cox had departed, Kevin shifted his attention inward, reaching for the familiar presence of AIDA in his consciousness.

  "Assessment of morning training effectiveness," he subvocalized, knowing the AI would register the internal query.

  AIDA's response materialized in his mind with clinical precision. "Subject Larissa demonstrates physical capabilities approximately 5.2 times human baseline. Notable attributes include enhanced strength, accelerated stamina recovery, and advanced proprioception. Combat effectiveness currently limited by lack of tactical training and technical refinement."

  "And my RTD usage?" Kevin prompted, recalling the brief bursts he'd employed during demonstrations.

  "Suboptimal efficiency," AIDA replied. "You're making progress in controlling the activation threshold, but your fine control needs work. Energy expenditure remains disproportionate to tactical advantage gained in non-combat scenarios."

  Kevin frowned slightly, taking a measured sip from his water ration. "Recommendations?"

  "Try visualizing the energy as flowing water rather than an explosion," AIDA suggested, her tone shifting to what Kevin had come to recognize as her teaching mode. "Your military background inclines you toward conceptualizing power as kinetic force, as sudden, explosive, maximum impact. For healing and precise RTD control, a more gradual, directed flow would improve efficiency."

  Kevin considered this, his enhanced mind mapping the conceptual shift required. He glanced at Larissa, who sat quietly beside him, methodically working through her protein bar. Her knuckles showed faint bruising from the morning's training, minor abrasions that would heal naturally within hours given her enhanced physiology, but which offered an opportunity to test AIDA's suggestion.

  "May I?" he asked, gesturing toward her hand.

  Larissa extended her arm without hesitation, trust evident in the simple movement. Kevin took her hand in his, turning it to examine the abraded knuckles. The damage was superficial, with broken capillaries beneath crimson skin and minor inflammation around the joints.

  He closed his eyes, accessing the red bar in his vision. Rather than reaching for the familiar surge of power that characterized his combat applications, he imagined the energy as AIDA had suggested, a controlled stream rather than an explosive release. He pictured the Redz40 in his system flowing like water from a narrow spout, directed with precision toward the damaged tissue in Larissa's hand.

  His palms began to glow with subdued crimson light, the energy transferring from his skin to hers in a controlled trickle rather than the flood he'd unleashed during her initial healing. The red bar in his vision dimmed only slightly, confirming AIDA's theory about improved efficiency. He maintained the connection for thirty seconds, focusing on the specific damaged areas rather than generalized healing.

  When he opened his eyes and released her hand, the bruising had vanished completely. The red bar had depleted by less than five percent, a fraction of what similar healing had previously required.

  "Impressive efficiency improvement," AIDA noted with what might have been satisfaction in a less clinical entity. "Energy consumption reduced by approximately 62% compared to previous healing attempts of similar magnitude."

  Larissa examined her knuckles with quiet wonder, flexing her fingers to test the results. "It felt different this time," she said. "Like cool water rather than fire."

  Kevin nodded, filing away this feedback for future refinement. "Different approach. Same result." He rose to his feet, checking the time. "Break's over. Let's continue."

  The afternoon session built upon the morning's foundations, with Kevin guiding Larissa through progressively more complex combat sequences. Without Cox present, they focused on technique rather than sparring, with Kevin demonstrating movements at normal speed, then having Larissa repeat them until the execution became fluid.

  Her natural aptitude for combat became increasingly evident as the hours passed. Where the morning had revealed her raw physical capabilities, the afternoon showcased her adaptive intelligence and kinesthetic learning. Techniques that might take an unenhanced recruit days to master, Larissa absorbed in hours, for her body seemingly remembering patterns after only a handful of repetitions.

  "Your center of gravity is still too high," Kevin instructed, circling her as she executed a complex takedown sequence against the training dummy. "Lower your stance. Power comes from the ground up."

  Larissa adjusted immediately, her next attempt noticeably improved. Her movements had transformed since the morning, the hesitation all but gone, replaced by growing confidence. She still relied too much on strength where technique would be more efficient, but the progress was remarkable for a single day's training.

  By late afternoon, Kevin had confirmed his initial assessment: Larissa possessed combat potential rivaling his own, though she lacked his experience and enhancement level. Her superhuman strength and stamina, combined with proper training, could indeed make her devastating in battle. Where Kevin's advantage came from his RTD manipulation and AIDA's tactical guidance, Larissa's came from raw physical power that seemed to grow more controlled with each passing hour.

  "Final drill," Kevin announced as the day's training neared its conclusion. "Full sequence, beginning to end. No hesitation, no breaks."

  He positioned himself in front of her, adopting an attacker's stance. Larissa centered herself, violet eyes narrowing with focus. When Kevin lunged forward, she responded with the accumulated knowledge of the day's training, blocking his initial strike, countering with precise targeting of vulnerable points, and using his momentum to execute a textbook takedown that ended with Kevin on his back, Larissa's forearm across his throat in perfect position for a killing strike.

  She held the position for a moment, their eyes meeting in mutual recognition of the significance: student besting teacher, if only because he had allowed it. Then she released him and stood, offering a hand to help him up with the same formal courtesy he had shown her throughout the day.

  "Good," Kevin said simply, accepting her assistance though he didn't need it. "Very good."

  As they gathered their training equipment, Kevin made mental notes for tomorrow's session. Larissa would need weapons training next, starting with knives, then progressing to firearms. Her hand-to-hand fundamentals were solid enough to build upon, her natural advantages compensating for her lack of experience.

  "AIDA, final assessment," he subvocalized as they prepared to leave the training area.

  "Subject demonstrates exceptional aptitude," AIDA replied. "Combat readiness timeline can be accelerated based on today's performance metrics. Recommend weapons introduction tomorrow, followed by small unit tactics by day five."

  Kevin nodded slightly, satisfied with the conclusion that matched his own. Beside him, Larissa moved with the quiet confidence of someone who had discovered a talent they hadn't known they possessed. The foundation had been laid; what would be built upon it remained to be seen.

  The dinner bell rang across Fort DC with the same mechanical precision that governed every aspect of life within its reinforced walls. Kevin and Larissa made their way toward the mess hall, their bodies bearing the subtle signs of a day spent in intense training: a slight stiffness in Kevin's movements, and a thoughtful distance in Larissa's violet eyes as she processed everything she'd learned. The corridors filled with off-duty personnel moving in the choreographed patterns of people who had internalized the settlement's rhythms and restrictions, their conversations creating a background hum of contained humanity.

  They entered the converted warehouse that served as the main mess hall for military personnel, the space dominated by long metal tables arranged in parallel rows beneath industrial lighting fixtures. The constant clatter of metal trays against metal surfaces created a percussive undercurrent to the controlled chaos of hundreds of soldiers taking their evening meal. Unlike breakfast, when units ate in shifts, dinner was a communal affair that saw most of Fort DC's military contingent gathered in one place.

  Kevin guided Larissa through the serving line, where UAC kitchen staff in stained white aprons ladled portions onto trays with efficient, impersonal movements. Tonight's meal was Blue stew, chunks of the iridescent meat they had harvested in Fairville, simmered in a thick broth with root vegetables. Beside it sat a strange, rice-like side dish that Kevin didn't recognize from previous meals.

  They found seats at a corner table with reasonable sightlines to the entrances, a tactical habit so ingrained in Kevin that he performed it without conscious thought. Larissa sat beside him, her posture alert but less tense than it had been that morning, the first subtle signs of adaptation to her new environment.

  "There you are," called a familiar voice from behind them. Kevin turned to see Duncan approaching, her usual composed appearance transformed by a comprehensive coating of machine grease. Dark smudges covered her face and arms, her blonde hair tied back in a messy ponytail that had clearly been repeatedly pushed out of her way during delicate mechanical work. She carried a heaping tray that threatened to overflow with Blue stew and the unidentified side dish.

  "Engineering bay?" Kevin asked as she dropped onto the bench across from them.

  Duncan nodded, immediately digging into her meal with the focused enthusiasm of someone who had forgotten to eat all day. "Weapon modifications," she explained between bites. "Been working on upgrading the assault rifle's focusing array. Theoretical twenty percent increase in penetration without additional energy consumption."

  Cox appeared moments later, her fur noticeably cleaner than when they'd parted earlier, her single eye scanning the crowded hall before settling on their table. She slid onto the bench beside Duncan, setting down her tray with precise movements.

  "What is this?" Kevin asked, gesturing to the rice-like side dish with his fork.

  Cox grinned, revealing sharp canines. "Protein supplement. Those aren't grains, they're meal worms that consume waste products before being harvested and cooked." She took a large bite of her own portion. "High protein, zero waste. Win-win."

  Kevin stared at his tray for a moment, centuries-old food preferences battling with the pragmatism of his military training. Practicality won, as it always did. He took a bite of the Blue stew first, finding the flavor surprisingly complex, a richness reminiscent of lobster but with undercurrents of something spicier, almost metallic. After a moment's hesitation, he tried the meal worm dish, discovering it had a nutty, almost pleasant taste that belied its origins.

  "Not bad," he admitted, taking another bite. Beside him, Larissa approached her meal with the methodical appreciation of someone who had known true hunger, wasting nothing and savoring each mouthful.

  As they ate, Duncan produced a worn tape measure from her pocket, her eyes narrowing with professional assessment as she studied Kevin and Larissa. "Need to get your measurements," she explained, rising from her seat and circling the table. "Stand up, both of you."

  They complied, standing side by side as Duncan took rapid measurements, shoulder width, arm length, torso circumference, inseam, calling out numbers that she jotted in a small notebook with a stubby pencil. Her fingers were precise despite the machine grease coating them, the measurements taken with the efficiency of someone who had performed similar tasks countless times.

  "Cox," Duncan said as she finished, returning to her meal. "I need to borrow your rifle."

  Cox's ears flattened immediately, her tail freezing mid-swish. "My baby? What for?"

  "Scope modifications," Duncan replied, unperturbed by the protective reaction. "I'm designing an integration system that would let you interface directly with Kevin's RTD capabilities during operations. Shared targeting data, synchronized engagement."

  Cox's expression shifted from suspicion to interest, her ears perking forward. "You mean I could see what he sees? Track through his enhanced vision?"

  "Potentially," Duncan confirmed. "Need your rifle to test the interface ports." She took another bite of stew. "I'll be careful with it."

  Cox considered for a moment, then nodded reluctantly. "Fine. But if you mess up the custom trigger pull, I'll bite you." The threat was delivered with enough humor to take the edge off, but Kevin detected the genuine concern beneath.

  "So," Duncan said, turning her attention to Larissa. "First day assessment?"

  Kevin wiped his mouth with a standard-issue napkin before responding. "She has significant potential. Enhanced strength approximately five times human baseline. Exceptional stamina. Learns combat movements after minimal repetition." He glanced at Larissa, who continued eating with focused attention. "With proper armor, she'd be a terror on the battlefield."

  Duncan nodded, unsurprised by the assessment. "Armor is the problem. Metal is scarce, so we prioritize it for infrastructure and essential equipment." She tapped her notebook. "For what you two need, custom weapons, reinforced armor that can withstand your enhanced strength, we'd need to scavenge at least one hundred to two hundred pounds from the wastes."

  Kevin considered this. "Requisition a Humvee. We could make a supply run to the outlying ruins."

  Duncan shook her head. "Won't get vehicle authorization for something this routine. President Wilson's restricting fuel usage after reports of Waste Mob movement to the north." She scraped the last of her stew from her tray. "Best we could get is a cart, maybe a horse if the quartermaster's feeling generous."

  "There's exposed rebar in those collapsed buildings south of here," Cox interjected, her tail swishing thoughtfully. "About five miles out, near the old highway interchange. Military-grade steel from pre-war construction." Her ears twitched forward. "With your strength and Larissa's, you could salvage enough in a day trip."

  Kevin nodded, already calculating the logistics. "How many personnel?"

  "Four," Duncan replied immediately. "You, Larissa, me for technical assessment of salvageable materials, and Cox for perimeter security." She glanced at Larissa. "Consider it a field training exercise. Controlled environment, minimal threat, practical application of today's lessons."

  Larissa set down her fork, meeting Duncan's gaze directly. "I'm in," she said, her voice carrying the quiet determination that Kevin had observed developing throughout the day's training. "I can pull my weight."

  "More than that," Cox added with a grin. "You can pull all our weights, plus a couple hundred pounds of metal."

  They spent the remainder of the meal planning the details of tomorrow's scavenging mission: departure time, equipment requirements, security protocols, and extraction plan if they encountered unexpected resistance. The conversation flowed with the practiced efficiency of experienced soldiers preparing for an operation, with Kevin and Duncan handling most of the tactical planning while Cox offered insights on potential threats in the area.

  Throughout the discussion, Kevin observed Larissa absorbing every detail, her violet eyes tracking from speaker to speaker, occasionally asking precise questions that revealed both her intelligence and her determination to contribute. She was learning not just combat techniques but the thousand unspoken rules and procedures that bound a military unit together, such as the language, the rhythms, and the underlying trust that turned individuals into a team.

  As they finished their meal and gathered their trays, Kevin felt a quiet satisfaction that went beyond the day's training accomplishments. Larissa had taken her first steps toward becoming not just a fighter but a soldier, someone who could be relied upon when the inevitable chaos of combat tested their preparations. Tomorrow's scavenging mission would provide a controlled environment to continue that development, building on the foundation they had established today.

  "0700 at the south gate," Duncan confirmed as they prepared to depart. "Light combat load, extra water. The buildings we're targeting are unstable, so we'll need to move carefully." She glanced at Kevin and Larissa. "Get some rest. Tomorrow we build you proper weapons."
