Chapter 10: The Compound's Echoes
The guest quarters were too quiet. The space was all soft lines and ambient lighting, a curated portrait of comfort that felt like a museum exhibit. Outside the floor-to-ceiling windows, the sky over the lake churned with bruised purples and greys, the water a sheet of hammered lead. The distant, persistent thrum of the Compound’s systems was a vibration in the bones, a reminder that they were inside a living, breathing machine.
Sage sat on the edge of a wide platform bed, her fingers tracing the raised weave of the duvet. She’d showered, changed into borrowed sweats that were too soft, and now felt more exposed than ever. Jake paced near the balcony doors, a caged animal marking the perimeter of its new enclosure. Steven stood at a sideboard, meticulously arranging a tea service he’d convinced a confused intern to procure.
Marc leaned against the window frame, watching the mist cling to the ancient oaks. “They’ll have preliminary results soon.”
“It’s been four hours,” Jake said, not stopping his circuit. “How many tests does it take to know you’re fucked up?”
“A comprehensive panel requires time,” Steven said, pouring hot water into a porcelain cup. The sound was absurdly loud. “Cell cultures, spectral analysis, cross-referencing with known threat databases. Bruce Banner is thorough. It’s a good thing.”
“Thorough got us grabbed off the tarmac,” Jake shot back.
A soft chime sounded from the door. It wasn’t a buzz or a knock. A polite, digital tone.
They all went still.
The door slid open without waiting for an answer. Tony Stark walked in, still in his clothes from the hangar, minus the armor. He looked wrung out. Bruce followed, holding a tablet, his expression the carefully neutral mask of a doctor bracing for impact.
“Hey,” Tony said, his voice lacking its usual performative edge. “We need to talk. All of you. Especially you,” he added, his eyes landing on Sage.
Steven set the teapot down with a precise click. “You have findings.”
Bruce swiped at the tablet, hesitated, then turned it to face them. On the screen was a rotating 3D model of a double helix, lit up with swirling markers in sickly green and invasive red. “We isolated the primary chemical regimen. It’s brutal. A suppression matrix targeting the amygdala and prefrontal cortex. It creates a dependency loop—disobedience triggers a simulated adrenal crash, profound anxiety. Compliance releases a micro-dose of synthetic oxytocin. A chemical carrot and stick.”
“We knew that,” Marc said flatly. “The Pharmacist’s signature.”
“Right. But that’s the software,” Tony said, moving to lean against the wall. He crossed his arms, but it looked defensive, not relaxed. “We started digging into the hardware. The base code. Her DNA.”
The room chilled. Sage slowly lifted her head.
“What about it?” she asked. Her voice was small.
Bruce zoomed in on the model. Sections of the helix glowed with an unusual, crystalline lattice structure. “There are… edits. Precise, surgical modifications at specific gene loci. This isn’t random mutation or damage. This is targeted enhancement. The chemical conditioning? It’s layered on top of this, like a operating system installed on custom hardware.”
Steven took a step closer, his doctor’s curiosity overriding his alarm. “Enhancement of what?”
Tony pushed off the wall. “We ran passive neural scans while she was in med-bay. Standard post-infection mapping. We found atypical dendrite formation in the parietal and temporal lobes. Hyper-myelinated neural pathways. And we picked up consistent, low-level quantum field distortion in the pineal region.” He paused, letting the jargon hang. Then he simplified. “Her brain is built to broadcast and receive. The conditioning makes her suggestible. The genetic edits… they gave her the tools to be something more.”
Jake stopped pacing. “Spell it out.”
Bruce did. “We believe the genetic manipulation was intended to create a low-level telepathic capacity. An ability to perceive and, potentially, influence neuro-electrical patterns in other brains. The chemical regimen was then applied to make that capacity obedient. To turn a potential weapon into a controllable one.”
Silence, thick and heavy.
Sage stared at the glowing helix. She shook her head once, a sharp, denying motion. “No. That’s not… I can’t read minds. I’d know.”
“Would you?” Bruce asked gently. “If you were conditioned from the outset to suppress it? Or if it manifests as something subtle—gut feelings, knowing someone is lying, intense empathy that you mistake for intuition? Have you ever just… known something about a person you shouldn’t? Felt a crowd’s mood as a physical weight?”
Her breath hitched. Images flashed, unwanted: the sterile room, the man in the lab coat she called The Pharmacist holding up placards with symbols, her guessing the next one before it was shown, the sharp, corrective sting from the IV in her arm afterwards. The constant, suffocating awareness of Marc’s coiled anger, Jake’s feral protectiveness, Steven’s clinical worry, as if their emotions were colors bleeding into her own.
“It’s just observation,” she whispered, but the protest was weak.
“We need to test the parameters,” Tony said, businesslike. “We need to understand the scope. And more importantly, we need to test the depth of the chemical leash. If we’re going to break it, we need to know its limits.”
Marc straightened. “Test how?”
Before Tony could answer, the door chimed again and slid open. Steve Rogers walked in, followed by Natasha. Steve’s face was all earnest concern. Natasha’s was unreadable.
“Bruce filled us in,” Steve said, his gaze moving from the tablet to Sage. “This is a serious development.”
“It’s a hypothesis,” Sage said, rallying a shred of defiance.
“One we can verify,” Natasha said. Her voice was calm, reasonable. “Steve.”
Steve nodded. He turned to Sage, and his posture shifted almost imperceptibly. His shoulders squared. His chin lifted. The warm, understanding Captain America veneer melted away, replaced by something older, harder—the Commanding Officer. The Strategic Homeland Intervention, Enforcement and Logistics Division asset.
“Sage,” he said, and his voice changed. It wasn’t louder. It was colder. Flatter. An iron rod of authority stripped of all empathy. “Stand up.”
The effect was instant and horrifying.
Sage’s body moved before her mind could protest. It was a jerky, marionette motion. She pushed off the bed and stood at a loose approximation of attention, her eyes wide with panic, fixed on a point past Steve’s shoulder. A full-body tremble started in her hands and radiated outward.
“Report your designation,” Steve commanded, the tone leaving no room for anything but compliance.
Her lips moved. A whisper, forced out. “Asset… Gamma-Seven.”
Jake took a step forward. “Hey, what the hell are you—”
Natasha put a hand on his chest. It wasn’t a push. It was a wall. “Wait,” she murmured, her eyes glued to Sage.
Steve continued, relentless. “What is your primary function?”
Tears welled in Sage’s eyes, spilling over. She fought to keep her voice steady and failed. “Passive… telemetric acquisition and behavioral… behavioral influence.”
“Who is your controller?”
“Director… Krivets.” The name was a sob.
“And your standing orders regarding this facility?”
She shook her head, the tremble becoming a shudder. “N-none. No orders. I am… compromised. I am… lost.” The confession was torn from her, drenched in shame.
Steve’s demeanor softened back into its familiar lines. “It’s okay, Sage. You can relax. The exercise is over.”
The release of tension was physical. She swayed, her knees buckling. Jake shook off Natasha’s hand and was there in two strides, catching her before she hit the floor. He lowered her back to the bed, his hands framing her face. “Look at me. You’re here. It’s Jake. You see me?”
She was hyperventilating, gasping, staring through him.
“What the fuck was that?” Marc’s voice was a low, dangerous thing, directed at Steve. He’d moved between them and the bed, his body a barrier.
“A diagnostic,” Steve said, his own face pale. He looked shaken by the violence of the reaction. “We had to see the programming in action. To confirm it was keyed to command authority, not just fear.”
“You triggered her!” Jake roared, spinning to face them, his body coiled to spring. “You saw what it does to her and you did it anyway!”
“We needed to know,” Natasha stated, still calm. Her eyes were on Sage’s shattered form. “Now we do. The conditioning is command-responsive. A specific tonal authority bypasses higher cognitive function. It’s a backdoor into her autonomy.”
Bruce was already moving, a scanner in his hand. He approached cautiously. “Her cortisol and adrenaline are spiking off the charts. Jake, let me check her.”
Jake didn’t move. Marc put a hand on his arm. “Let him.”
Slowly, Jake stepped back, his chest heaving. Bruce ran the scanner, his frown deepening. “Neural activity is… chaotic. There’s feedback. Like the command sparked something and it’s short-circuiting.”
Sage’s gasps began to even out. Her wide, terrified eyes blinked, focusing on Jake, then Marc, then Steven. The raw, programmed shame was receding, replaced by a dawning, horrified comprehension. And beneath that, something else. A prickling static at the base of every skull in the room.
She looked at Tony, who was watching her with intense scientific focus. ‘Cold, calculating, needs data, afraid of what he doesn’t understand, afraid of me—’
The thoughts weren’t hers. They slammed into her consciousness, fully formed, in Tony’s own mental voice.
She flinched as if struck.
Her gaze snapped to Natasha. ‘Assessing threat level, calculating response times, body positioning for three separate disarm maneuvers, concern for Rogers’s guilt, file on Krivets incomplete—’
“Stop,” Sage whimpered, clamping her hands over her ears. It did nothing. The voices weren’t sound. They were impressions, textures, thoughts leaking from their skulls like water from a cracked glass.
Steve took a step closer, his thoughts a storm of grim resolve and protective guilt. ‘Necessary evil, but an evil, have to contain this, have to help her, what have we unleashed—’
“GET OUT!” The scream tore from her throat, raw and desperate.
The static pressure spiked. A glass of water on the sideboard shattered. Not from vibration. It simply imploded, shards spraying across the polished wood.
Everyone froze.
Sage stared at the broken glass, then at her own hands. The psychic noise in her head was a roaring waterfall—Jake’s molten rage, Steven’s frantic clinical analysis, Marc’s icy strategic calculations, the Avengers’ alarm—all crashing together.
She found Marc’s eyes in the maelstrom. His mental presence was a strange, fractured steadiness. A chaos that was familiar. An anchor.
“Make it stop,” she pleaded, the words barely audible.
Marc moved. He didn’t touch her. He placed himself directly in her line of sight, blocking her view of the others. “Look at me. Just me.” His voice was a command, but not like Steve’s. It was a rope thrown into deep water. “It’s in your head. It’s your head. You control the door. Not them. You.”
She focused on his face, on the scar above his brow, on the relentless darkness in his eyes that mirrored the one growing in her. The cacophony receded, just a fraction, muffled by the force of his will.
“Breathe,” he said.
She breathed.
The psychic storm didn’t cease, but it banked, becoming a manageable, terrifying hum at the edge of her awareness. She could still feel them. All of them. Their suspicion, their fear, their plans.
Tony Stark let out a long, slow breath. “Well,” he said, the word hanging in the silence broken only by Sage’s ragged breathing and the hum of the Compound. “The enhancement works. And it’s reactive to extreme stress.”
Bruce looked from the broken glass to his scanner readings, his face ashen. “The genetic potential is active. And it’s tied to her emotional state. The conditioning tried to build a lock on it.” He met Steve’s gaze, a world of trouble in his eyes. “We just blew that lock off its hinges.”
Steve Rogers looked at Sage, who was now clinging to consciousness, her mind an open wound, her eyes seeing too much. He saw the weapon Krivets had tried to forge. He saw the terrified woman buried underneath.
And he saw the unbearable truth: they hadn’t just brought her into a sanctuary. They had brought a lit fuse into a powder keg of secrets, and the first spark had already caught.
They had brought a lit fuse into a powder keg of secrets, and the first spark had already caught.
Tony Stark was the first to move after the glass exploded. He didn’t flinch at the shards. He looked from the mess to Sage’s ashen, trembling face, and something in his own expression fractured. The clinical detachment evaporated. “Okay,” he said, his voice dropping into a softer, steadier register. “Enough proving the point. Everyone out. Now. Give her air.”
Steve opened his mouth, likely to protest or organize, but Natasha touched his elbow. A silent communication passed between them. With a final, heavy look at Sage, Steve turned and led Natasha from the room. Bruce hesitated, scanner still whirring. “Tony, the neural feedback—”
“We’ll monitor remotely,” Tony said, not looking at him. His eyes were fixed on Sage. “Patch the feeds to my private server. Not the main diagnostic array. Encrypted.”
Bruce understood. Contain the information. He nodded and followed the others out.
Jake hadn’t moved from Sage’s side. Steven stood frozen by the shattered glass, his clinical mind clearly struggling to categorize the phenomenon. Marc remained planted before Sage, a bulwark.
“You too, Crichton,” Tony said to Steven, then glanced at Jake and Marc. “For a minute. Just a minute. She’s not going to implode. And if she does, I’ve got better insurance than you.”
Marc studied Tony’s face. He saw the calculated risk, but beneath it, a new urgency that had nothing to do with data acquisition. He gave a sharp nod to Jake. “Outside. Right outside.”
Jake’s jaw worked, but he reluctantly released Sage’s hand and backed toward the door, his gaze promising violence if this went wrong. Steven followed, meticulously stepping around the glass. The door slid shut, leaving Tony alone with Sage and Marc.
The psychic noise in Sage’s head had dampened to a terrible, ringing hum with only two primary sources left. Marc’s was a turbulent but familiar storm. Tony’s was a torrent of focused, technical concern, laced with a sharp, surprising thread of guilt.
“It’s like tinnitus, isn’t it?” Tony said, dragging a chair over and sitting down a careful distance away. He didn’t try to touch her. “A ringing in your skull that’s not sound. I get the phantom vibration of a phone in my arc reactor socket. Drives me nuts.”
The bizarre, specific analogy cut through Sage’s panic. She blinked, focusing on him. “It’s… voices. Whispers. Your thoughts.”
“I figured.” Tony leaned forward, elbows on his knees. “You heard me thinking you were a problem. You heard Cap thinking he was doing the right thing. It’s a crap way to get to know people.” He paused. “My turn to guess. Right now, you’re probably hearing me run about seventeen diagnostic simulations in my head, trying to model the quantum field distortion. And you’re hearing that I’m pissed at myself for letting Rogers do the hardass routine.”
Sage gave a tiny, miserable nod. “You called it a necessary evil. In your head.”
“Yeah. And I was wrong. It was just evil. A dumb, brute-force play.” He scrubbed a hand over his face. “We’re not gonna do that again. New rule: no one speaks to you in a command voice. Ever. If they do, Jarvis mutes them. I’ll write the protocol myself.”
The offer was so practical, so unexpectedly protective, that it momentarily stifled the psychic static. Marc watched, silent, assessing this shift.
“It won’t stop the noise,” Sage whispered.
“No,” Tony agreed. “But it’ll stop the triggers. The rest? We figure that out. You’re not the first enhanced person to have a glitchy OS.” He managed a weak smirk. “Hell, I’m basically held together by electromagnets and poor decisions. We’ll debug this.”
Over the next two days, Tony became a persistent, low-key presence. He didn’t hover. He just appeared. He brought a sleek, non-invasive neural monitor shaped like a behind-the-ear comm piece. “Filters external noise, gives you a readout of your own brainwaves. Think of it as a meter for the static. You see it spiking, you know it’s you, not the room.”
He had food sent up that was high in specific amino acids Bruce recommended for neural repair. He didn’t comment when she barely touched it. He’d just swap the tray for something else an hour later—a smoothie, a bowl of berries—until she found something she could stomach.
He talked. Not at her, often not even to her. He’d work on a holographic schematic in the corner of her room, muttering about impedance and synaptic firing thresholds. He’d share inconsequential stories about lab accidents, about Rhodey, about the time a prototype repulsor fused his favorite screwdriver to a workbench. It was constant, casual noise that gave her a benign focus, a mental track to follow besides the torrent.
The paternal edge wasn’t stated. It was in the consistency. The lack of expectation. The way he’d frown at her monitor readings not with scientific excitement, but with genuine worry. He saw the weapon, yes. But he’d started seeing the scared kid who’d been built into one, and something in that resemblance to other lost, gifted kids he’d known stirred an old, rusty protectiveness.
On the third morning, new voices approached down the hall. Sage tensed, the monitor behind her ear giving a soft, warning chime. Tony, who was adjusting the environmental controls to a slightly lower barometric pressure he theorized might help, didn’t look up. “That’ll be the marginally-less-intimidating committee. I called in some specialists.”
The door slid open. Peter Parker stood there, looking about as comfortable as a guest at a funeral. He offered a small, awkward wave. “Um. Hi. Mr. Stark said you could use a… a normal person? I’m maybe not the best example of normal, but I don’t do the commanding voice thing. Ever.”
Beside him, Bucky Barnes stood with his metal arm held deliberately still at his side. His gaze was direct, but there was a hollowed-out understanding in it. “Heard you got a playlist stuck in your head you didn’t choose,” he said, his voice low. “Sucks.”
Sage’s eyes darted between them. Peter’s thoughts arrived first—a rapid-fire, nervous stream of ‘ohman she looks tired is this a bad time I should’ve brought something maybe a cookie Mr. Stark didn’t say bring a cookie’—but it was warm, without a shred of malice. Bucky’s mental space was quieter, heavily shielded, but what seeped through was a deep, resonant recognition of forced programming, of fighting the wiring in your own skull.
Their clarity was startling. Unlike the Avengers’ strategic complexities, these were simpler, brighter frequencies. She found herself able to separate their threads from the background hum without the usual migraine pressure.
“Peter’s here because his senses dial to eleven sometimes, too,” Tony said, finally turning. “He knows about sensory overload. And Barnes… well, he knows what it’s like when other people’s words are in your driver’s seat.”
Bucky gave a single, shallow nod. “The words fade. Doesn’t feel like it, but they do. You learn the triggers. You learn to muffle the volume.”
“We could, uh, we could watch a movie?” Peter suggested, shifting his weight. “Something loud and dumb. It can help. Sort of gives your brain one big thing to focus on instead of all the little ones.”
It was a small, decent offer. Before Sage could respond, another figure appeared in the doorway. Wanda Maximoff. She wore soft clothes, not her combat suit, and her hands were tucked into the pockets of a dark sweater. Her expression was solemn, but not unkind.
“Tony said you are drowning,” Wanda said, her accent softening the blunt words. “I know this feeling. May I come in?”
Tony nodded almost imperceptibly to Sage. She wrapped her arms around herself but didn’t object. Wanda entered, and the room changed. Not physically. Atmospherically. The chaotic mental energy seemed to calm, to settle, as if someone had turned down a gain knob.
“You are pulling at everything,” Wanda observed, stopping a few feet away. Her gaze was distant, as if listening. “You have no filter. It is like standing in a storm with no skin.”
“Yes,” Sage breathed, the description painfully exact.
“The mind is not a fortress to be locked. It is a room. You must learn where the doors are. And the windows.” Wanda extended a hand, palm up. Crimson energy, delicate as mist, coiled around her fingers. “My power is different. It is chaos magic. But the hearing… the feeling of other minds… this I know. I can show you how to not listen.”
Sage looked at the offered hand, then at Tony. He gave her an encouraging nod. She looked at Marc, who had remained a silent statue by the window throughout. His gaze told her it was her choice.
She placed her hand in Wanda’s.
The world didn’t vanish. It simplified. The riot of color and noise that was the Compound’s psychic footprint—the anxiety of the junior agents three floors down, the focused intent of Steve in the gym, the endless digital stream of Jarvis’s periphery consciousness—all of it muted, softening into a distant, muted backdrop.
In the foreground, only Wanda’s presence remained, a clear, solid signature. ‘Like this,’ Wanda’s voice sounded, not in her ears, but directly in her mind, clean and without static. ‘You build a wall not of stone, but of intention. You decide what is the signal, and what is the noise. Right now, I am the signal. Everything else is noise. Push it away.’
Sage tried. She mentally reached for the chaotic buzz, pushing against it. It surged back, overwhelming.
‘No. Not a push. A selection. Listen for my breath. Only my breath.’
Sage closed her eyes. In the tempest, she found the rhythmic, steady sound of Wanda breathing. She fastened onto it. She let the rhythm become a path, a single thread through the madness. Slowly, agonizingly, the cacophony began to recede, not gone, but organized, held at bay behind a sheer, trembling wall of focus.
She was breathing in time with Wanda. The pressure in her skull eased from a scream to a murmur.
When she opened her eyes, tears were streaming down her face from the relief. Wanda released her hand, the scarlet mist fading. The noise rushed back in, but slightly quieter, and now she knew the shape of the wall she needed to build.
“It will not hold for long the first times,” Wanda said quietly. “You will be tired. But now you have felt the shape of the door. You can find it again.”
Sage slumped back, drained but clearer-eyed than she’d been in days. Tony let out a breath he seemed to have been holding. “Okay. Progress. Real, actual, non-exploding progress.”
Peter grinned, a bright, genuine thing. “That was so cool.”
Bucky just watched, that understanding still in his eyes. He knew the exhaustion that followed wrestling your own mind into temporary submission. It was the fatigue of a war fought in absolute silence.
Marc finally moved from the window. He approached, looking down at Sage. The storm in his own mind felt quieter to her now, or perhaps she was just learning to navigate it. “You good?”
She met his gaze. For the first time since the jet, she felt a flicker of something besides terror or resignation. It was fragile, but it was agency. “I found the door,” she said, her voice hoarse.
Tony clapped his hands together softly. “Great. Lesson one: complete. Now, you need to sleep. Real sleep. Wanda, you’re officially on retainer. Barnes, Parker—you’re on the non-intimidating visitation roster. Keep the noise normal.”
As the others filtered out, Tony lingered. He picked up the untouched berry bowl and replaced it with a glass of water and a single, simple protein bar. “Start small,” he said, not looking at her. “The mind’s a energy hog. Gotta fuel it.”
He was almost at the door when her voice stopped him. “Stark.”
He turned.
“Thank you,” she said. It was barely audible.
He gave a small, dismissive wave, but the line of his shoulders softened. “Don’t thank me yet. We still have to figure out how to uninstall the malware. Get some rest.”
The door closed. Sage was alone with Marc, the ghost of Wanda’s lesson still a palpable structure in her mind. The fuse was still lit. The powder keg was still there. But for the first time, she had a faint glimpse of how to direct the spark.
