Kai stood in the hallway outside Morrison's office, his mind racing.
He needed to move, to process, but he also needed to be strategic about his next forty-three minutes. He had multiple critical tasks and limited time.
He found a records terminal on the floor—public access for administrative purposes. He sat down, logged in with his recruit credentials, and pulled up Morrison's official file.
MORRISON, REBECCA - LIEUTENANT, INTELLIGENCE DIVISION
Service record: Seven years. Consistently high performance reviews. Multiple commendations for signals intelligence and cryptography. No disciplinary actions.
Family connections: Father was a settlement administrator, mother worked in communications.
Interesting detail: She requested transfer to Intelligence Division specifically three years ago after working in field operations. The timing was noted in her file—shortly after increased Colorado transmission activity began.
He dug deeper. Her official communication logs were restricted, but he could see the summary data.
High volume of encrypted communications in the last six months, 40% increase over previous period. Destinations: Multiple wasteland settlements, three marked as "Colorado region."
He took a mental snapshot of everything and closed the terminal. Ten minutes gone.
Next: Wolfe. He moved quickly down the corridor to her office. Her door was closed but unlocked—he knocked.
"Enter."
Wolfe was at her desk, reading reports. She looked up, saw his expression, and immediately stood.
"How did Morrison's assessment go?"
"Successfully, ma'am. She approved me for mission deployment." He closed the door behind him. "But there's more. She knows something."
He gave her the compressed version—Morrison's questions about the Colorado transmissions, her observation about "textbook-perfect" grammar patterns, her warning to be careful about conclusions from incomplete data.
The fact that she had unofficial contacts in Colorado reporting people who disappear and get replaced with people who act "almost right but not quite."
Wolfe listened, her expression growing darker. "She's investigating independently."
"Yes, ma'am. And she warned me that my father asked similar questions and to be smarter about it than he was."
He paused. "She either suspects the same thing we do, or she's trying to determine how much I know."
"Or both." Wolfe moved to her window, looking out over the Citadel. "Morrison is ambitious but not stupid. If she's pieced together the same pattern from the transmissions..."
She turned back. "Did she ask you directly about synths?"
"No, ma'am. But I commented on the artificial language patterns and she told me to be very careful what conclusions I draw from incomplete data."
"That's a warning. She's telling you she knows you're close to something dangerous."
Wolfe's jaw tightened. "She could be an asset or a liability. Her ambition makes her unpredictable."
"There's something else, ma'am." He pulled out the folded note from his pocket. "I received this during PT this morning. From whoever's been watching me—the figure people call 'Ghost.'"
Wolfe read it quickly, her expression unreadable.
When she finished, she looked up. "Captain Cross has unredacted files. Sergeant Kozlov has your father's letter. And the synth identification method is in Sokolov's lab."
"Yes, ma'am. The note is specific enough to be credible."
"Or specific enough to be a trap leading you exactly where someone wants you to go."
But she didn't sound like she believed it was a trap. She sounded thoughtful. "Cross is... complicated. He's a bureaucrat, not a fighter, but he's meticulous. If he kept copies of destroyed documents, it's because he doesn't trust command to preserve the truth."
"Should I approach him, ma'am?"
"Not yet. Let me feel him out first." She handed the note back. "But Sokolov—you have legitimate reason to visit her lab for the technical consultation Morrison scheduled. Look for that file while you're there. 'Acoustic Analysis Protocols - Pre-War AI Research.' If it exists, it could give us the identification method we need."
"And Sergeant Kozlov?"
"He served with your father. If he's kept a letter for fifteen years..."
Wolfe's expression softened slightly. "Viktor Kozlov is old school. Honor, duty, and the Ranger code above everything else. If he's waiting for the right questions, it's because he's protecting something he thinks should only be shared with someone who deserves it."
"How do I earn that, ma'am?"
"By proving you're your father's son in more than just name."
She moved back to her desk. "Be careful today, Chen. You're juggling multiple investigations, Morrison is watching you, and you're running on no sleep. Don't make mistakes."
"Understood, ma'am."
He exited her office with twenty-three minutes until Sokolov. He needed to find Zara briefly.
He headed toward the training facilities where recruits would be during mid-morning drills. He spotted her on the shooting range, methodically working through precision drills with a rifle.
She saw him approaching and, after completing her current shot, called a brief pause.
She met him at the edge of the range, away from other recruits. "You survived Morrison."
"Barely. We need to talk, but I've only got a few minutes."
"Make them count."
He spoke quickly, keeping his voice low. "Morrison suspects the same thing we do. She didn't say it directly, but she knows about the artificial speech patterns in Colorado transmissions. She's been investigating independently, has contacts in the region reporting people who get replaced with others who act 'almost right.'"
Zara's expression didn't change, but her eyes intensified. "She knows about the synths."
"Suspects, at minimum. And she warned me to be careful about the conclusions I'm drawing."
He glanced around—no one was in earshot. "The question is whether she's investigating because she wants to expose it, because she wants to use the information for career advancement, or because she's trying to determine if I'm a threat to the operation."
"All three could be true simultaneously." Zara adjusted her rifle. "What's your read on her trustworthiness?"
"Complicated. She's ambitious, which makes her predictable in some ways—she wants the Colorado mission to succeed. But ambitious people make dangerous allies because their loyalty is to their advancement, not to you."
"So we don't trust her completely, but we use her resources where we can."
"Exactly." He checked his watch. "I need to get to Sokolov's lab in fifteen minutes. But I wanted to let you know—Morrison's assessment went well. I'm approved for mission deployment. You should be too, based on your performance."
"Already got the notification an hour ago." She picked up her rifle again. "We're both going to Colorado, apparently. Along with Marcus Webb, Darius, and a few others from our training class."
His heart skipped. "Official team assignments?"
"Preliminary. Final team gets chosen after we complete tactical certifications."
She loaded another magazine. "Which means we have maybe two weeks to identify who we can actually trust on that team before we're walking into synth central."
Two weeks. It wasn't enough time, but it was what they had.
"I'll find you after the Sokolov meeting," he said. "Compare notes tonight?"
"Bay 3, after lights out. I'll find a reason to stop by." She raised the rifle. "And Chen—good work surviving Morrison. Most recruits would've folded under that kind of pressure."
He headed back toward the main Citadel complex, using the walk to mentally prepare for Sokolov.
The laboratory building was separate from the main facilities, nestled against the eastern wall. As he approached, he could hear classical music—Beethoven, he thought—playing from inside.
He knocked on the door.
"Come in! It's unlocked!" The voice was female, distracted, slightly impatient.
He entered.
The lab was organized chaos. Workbenches covered with disassembled electronics, computer terminals in various states of functionality, chalkboards filled with equations and diagrams.
Shelves packed with technical manuals and components. A coffee maker producing what smelled like burnt rubber. And plants on the windowsill that someone was clearly talking to.
Dr. Elena Sokolov was bent over a terminal, hair in a messy bun with pencils stuck through it, wearing a lab coat covered in coffee stains. She was muttering to herself in Russian—technical jargon mixed with what sounded like curse words.
"Dr. Sokolov?" he said.
She jumped slightly, spun around. Behind pre-war reading glasses, her grey eyes were sharp, intelligent, and currently focused on him with the intensity of someone who forgot a person was coming.
"Oh! Right! The linguistic consult!" She pushed her glasses up her nose. "You're Chen. Morrison said you'd be here at 1030. You're..." she checked a clock on the wall, "two minutes early. Good. Punctuality suggests respect for other people's time, which I appreciate."
She gestured vaguely at the chaos. "Sorry about the mess. I was working on something and lost track of... well, everything. Have you eaten? I have terrible coffee and some protein bars that are probably expired but technically non-perishable."
He couldn't help but smile slightly. This was nothing like Morrison's cold psychological warfare.
"I'm fine, thank you, Dr. Sokolov. Lieutenant Morrison said you needed linguistic consultation on some technical analysis?"
"Yes! Well, no. Well, sort of." She moved to one of her terminals, gesturing for him to follow. "Morrison thinks you're here to help me translate technical documents. Which you might. But really I think she wanted to see if you'd ask dangerous questions about AI systems."
He froze. Sokolov didn't notice, continuing to pull up files.
"See, the thing is, I'm terrible at subterfuge. Absolutely awful. When Morrison asked me to schedule a 'technical linguistics consultation' with you, I knew it was a test. She wanted to see if you'd probe about artificial intelligence and synthetic speech patterns."
She finally looked at him. "Which, honestly, if you're smart—and your file says you are—you absolutely should ask about. Because that's the real question underlying the Colorado transmissions, isn't it?"
He stared at her. "Dr. Sokolov—"
"Elena. Please. 'Doctor' makes me sound like I know what I'm doing."
She sat down, gesturing to a chair. "Look, I'm a scientist. I deal in observable data and testable hypotheses. And the observable data from the Colorado transmissions includes multiple anomalies consistent with artificially generated speech patterns."
She pulled up waveform analysis on her screen. "See this? Human speech has natural variations—breathing patterns, micro-pauses, harmonic irregularities based on emotional state and physical condition. But some of these transmissions..."
She pointed to specific patterns. "They're too consistent. Too perfect. Like they were generated by a program trying to replicate human speech without fully understanding the organic imperfections."
His heart was pounding. She was just telling him this. No games, no manipulation.
"Have you reported this to anyone?" he asked carefully.
"Of course. Morrison, Commander Wolfe, the technical review board."
She pushed her glasses up again. "They all said 'interesting observation, continue monitoring.' Which is bureaucrat-speak for 'we already know and don't want to discuss it.'"
She turned to face him fully. "So here's my question for you: Are you actually here to help me translate boring technical documents, or are you trying to understand how to identify synthetic humans based on vocal analysis?"
He stood at a critical decision point. Sokolov was being disarmingly honest, possibly because she was genuinely terrible at deception.
But this could also be an elaborate test.
He made his choice. Her directness was either genuine or the most sophisticated performance he'd ever encountered.
But right now, he needed someone who could help him understand the technical side of what his father discovered.
He pulled the chair closer and sat down, meeting her eyes directly.
"I'm here because my father, Marcus Chen, was killed in Colorado fifteen years ago trying to expose something about the Patriarch's regime. Last night I listened to his final transmission—heavily corrupted, mostly static, but what came through mentioned synthetic humans and an AI facility beneath Colorado Springs."
He kept his voice steady, factual. "He said there was a way to identify synths through some kind of auditory test, something about frequency response patterns. Then the transmission cut to static and he died."
Sokolov's eyes widened behind her glasses. She didn't speak, just listened intently.
"Morrison knows I'm asking questions. Commander Wolfe gave me access to the classified files because she wants the truth too. And I'm here because you're the only person in this facility who might actually be able to help me understand the technical side of what my father discovered."
He paused. "Not the politics, not the conspiracy, not who's compromised in command—just the science. How do you identify a synthetic human? What are the vocal patterns that give them away?"
Sokolov was quiet for a long moment. Then she stood abruptly and moved to her door, checking the hallway.
Empty. She closed it and locked it.
"Okay," she said, returning to her terminal. "Okay. Yes. This makes sense now."
She was talking rapidly, her hands moving as she thought. "Morrison's been asking me to analyze Colorado transmissions for months. Wolfe requested technical assessments on pre-war AI capabilities. I thought they were just being thorough, but they were looking for the same thing you are."
She pulled up multiple files on her screen. "Pre-war synthetic humans—there were experimental programs before the bombs fell. Mostly classified military research. The goal was to create infiltration units that could pass as human in enemy territory. The technology was..." she searched for the word, "incomplete. They could replicate appearance, basic behavior, speech patterns. But there were limitations."
"What kind of limitations?"
"Vocal synthesis was the big one." She pulled up a waveform analysis diagram. "Human vocal cords produce sound through organic vibration—muscles, cartilage, breath control. It's inherently imperfect and variable. Synthetic vocal systems could produce the right phonemes, the right words, even simulate emotion. But under certain conditions, they couldn't replicate the harmonic complexity."
She was getting excited now, in the way scientists do when explaining their field. "Specifically, when stressed or required to produce complex emotional vocalizations rapidly, human voices create what we call 'harmonic distortion patterns'—irregular frequencies that result from involuntary muscle tension, breathing changes, genuine emotional response. Synths could fake the surface characteristics, but the underlying harmonic structure would be too clean. Too consistent."
"So if you put someone under vocal stress and analyzed their speech patterns..."
"You could theoretically distinguish synthetic from human, yes." She pulled up another file. "But you'd need the right equipment and the right testing protocol. It's not something you could do casually. You'd need specific frequency analysis, controlled conditions, and..."
She trailed off, looking at something on her screen.
"What?" he asked.
"I have this file." She was clicking through folders. "When I first got assigned here, they gave me access to the old pre-war research archives. Most of it is weapons systems, power generation, that kind of thing. But there was one folder labeled 'Acoustic Analysis Protocols - Pre-War AI Research.' I skimmed it once, thought it was about using AI for sound analysis. But if what you're saying is true..."
She found the file and opened it.
The document was dense—technical specifications, testing protocols, equipment requirements. But the title made his heart race:
CLASSIFIED: Acoustic Identification of Synthetic Vocal Systems - Field Testing Protocol
"This is it," he breathed. "This is what my father found."
Sokolov was reading rapidly, her eyes moving down the screen. "Oh. Oh, this is brilliant. Look—they developed a portable testing device. It could analyze vocal harmonic patterns in real-time under induced stress conditions. The test subject wouldn't even know they were being evaluated if you did it correctly."
She scrolled down. "The equipment specifications are here. We could build this. I could build this."
"How long would it take?"
"With the right components? Maybe a week. Two to be safe." She was already making notes. "The hardest part would be calibrating it without raising suspicions. I'd need to test it on known humans first to establish baseline readings."
He leaned forward, reading over her shoulder. The protocol was detailed, providing exact specifications for testing.
"This could work," he said quietly. "But we'd need to be careful. If there are synths in the Citadel and they realize we have an identification method..."
"They'd eliminate the threat. Us." Sokolov removed her glasses, cleaning them absently. "This is real, isn't it? This isn't just theoretical concern. You genuinely believe there are synthetic infiltrators here."
"My father died believing it. Lieutenant Rivera, who decoded the transmission, died three months later under suspicious circumstances. General Hardeman, who ordered the investigation closed, retired wealthy with wasteland faction connections."
He met her eyes. "And now the Patriarch is inviting Rangers to Colorado after fifteen years of silence. Either the synth program is gone and he's confident we won't find evidence, or it's so successful he doesn't care if we know."
Sokolov put her glasses back on. "As a scientist, I should be skeptical. Demand more evidence. But..."
She gestured at her screen. "The data supports your hypothesis. The speech anomalies in Colorado transmissions. The fact that this identification protocol exists and was classified. The pattern of silencing people who asked questions."
She was quiet for a moment. "My job is to understand how things work. And this... this explains things that didn't make sense before."
"Will you help me?" he asked directly. "Not just with the science, but with building the device? We need a way to identify synths before we walk into Colorado."
She considered for a long moment. "If I do this—if I build this device—we're both taking enormous risks. If you're right and there are synths in command or among the Rangers, they'll see us as threats. If you're wrong, we'll have wasted resources and time on paranoid conspiracy theories."
"I know."
"But," she continued, "I became a scientist because I care about truth. Observable, testable truth. And if there's even a chance that synthetic infiltrators are a real threat..."
She stood decisively. "Yes. I'll help you. But we do this carefully. I'll build the device as part of my regular research into Colorado communication systems. If anyone asks, I'm developing better transmission analysis equipment. Which is technically true."
"How soon can you start?"
"I'll need to requisition components, which will take a few days. I'll have to be strategic about what I order so it doesn't raise red flags."
She was already making a list. "And I'll need test subjects—people we know are definitely human—to calibrate the baseline readings."
"How can we be certain anyone is definitely human?"
She paused, then smiled slightly. "Good point. That's the paradox, isn't it? We need to test people to identify synths, but we need known humans to calibrate the test."
She thought. "Long-term Rangers who served before the synth program could have infiltrated this far. Veterans who've been here for twenty, thirty years. The program your father discovered was fifteen years ago—anyone who predates that should be safe."
"Kozlov," he said. "He's been a Ranger for over twenty years."
"Perfect. I can run 'communication efficiency tests' on senior personnel as part of my research. They won't know they're being screened for synthetic vocal patterns."
She was getting more animated. "This could actually work."
Sokolov pulled out a data chip, loaded the file, and handed it to him. "The full technical specifications are on there. If something happens to me, you'll have the information to build the device yourself. Or find someone else who can."
He took the chip, feeling its weight. "Thank you."
"Don't thank me yet. We still have to actually make this work."
She glanced at the clock. "You have about twenty minutes left in our 'consultation.' Want to actually look at some boring technical translation work so Morrison's test has plausible deniability?"
He almost laughed. "That would be smart."
For the next twenty minutes, they translated technical specifications while Sokolov took notes. It was mundane work, but it provided cover for what they'd actually accomplished.
