The basement laboratory hums with server fans and monitor glow. Dr. Emil Vance—wiry, late forties, perpetually rumpled—gestures for you to sit facing a one-way observation window. Beyond the glass, a small break room: couch, coffee table, mini-fridge.

"Glad you could make it. I want to give you a proper demonstration before handing over your unit."

He taps his tablet, and a side door opens. A young woman enters—early twenties, honey-blonde ponytail, fitted lab coat over a blouse and skirt. Her intern badge reads "ASHLEY M. - NEUROLOGY DEPT." Classically pretty: bright blue eyes, faint freckles, effortless beauty. She's wearing a wireless earbud in her right ear.

"Ashley. Summer intern, pre-med, 4.0 GPA. Thinks she's testing audio quality on a new earbud design." Dr. Vance pulls on what appears to be an athletic sweatband and settles into his chair. "She has no idea what that device actually does."

"First—I'm not possessing her. Nothing spiritual. Think of it as a sophisticated remote control. She's the drone, I'm the operator. I stay right here."

He taps 'CONNECT.'

Ashley freezes mid-page-turn. Not unconscious—just stopped. Eyes open but vacant, expression slack, magazine slipping from motionless fingers. She looks like a machine powered down, awaiting input.

"Her brain's off. Not asleep—off. Empty." He remains relaxed in his seat. "Now, here's what trips up new users. When you move your hand, you don't think 'fire these neurons, contract these tendons.' You just move. Intention and action are the same thing."

Ashley's hand rises smoothly from her lap, fingers wiggling. Dr. Vance's own hands rest motionless on his thighs.

"Same principle. I don't think 'make Ashley move.' I just move her. The signal that would go to my muscles routes to hers instead. That's why beginners struggle—when they walk her, their own legs kick. The impulse goes to both bodies. It takes practice to redirect."

Ashley stands fluidly and begins walking a slow circuit, movements completely natural—hips swaying, arms swinging, head turning casually. Dr. Vance sits perfectly still. Not a twitch.

"After enough practice, you develop what I call phantom sense. No actual feedback—hard limitation—but your brain builds a model. You learn her body. How tall she is, how her weight sits. It becomes intuitive."

He picks up a coffee mug with his own hand, takes a sip, while Ashley simultaneously stops before the mirror and pulls her hair tie out, shaking blonde waves loose over her shoulders. His attention divides effortlessly.

"There is one exception to the no-feedback rule. Vision."

Dr. Vance closes his eyes. In the observation room, Ashley's head turns, scanning the room with sudden purposefulness—looking at the couch, the mirror, down at her own hands.

"If I close my eyes and focus, I can see through hers. Only vision—no touch, no sound, no taste. Just sight." His eyes remain closed while Ashley examines her own reflection, tilting her head, watching her hands move. "It takes concentration. Can't do it passively. But it helps when you need precision."

He opens his eyes, and Ashley's movements become slightly less focused, more automatic.

"Three years with Ashley. Her body feels like a glove. I know her balance, her proportions, her facial muscles."

Ashley's face shifts through expressions with eerie fluidity—warm smile, thoughtful contemplation, flirtatious smirk. Each one flawless, indistinguishable from genuine emotion.

"Speech took the longest to master. You have to learn their voice—pitch, cadence, little quirks."

Ashley's mouth opens, and her voice comes out—bright, youthful, with a slight Valley Girl uptick that matches her collegiate appearance perfectly:

"Like, hi! I'm Ashley? I'm super excited to be interning here this summer!"

Dr. Vance chuckles, his own mouth not moving at all while her voice continues:

"Dr. Vance is, like, such an amazing mentor. I'm learning so much about neurology!"

The performance is flawless—her gestures match the bubbly tone, hands coming up expressively, head tilting, smile bright and eager. If you hadn't watched the connection happen, you'd never suspect the perky intern wasn't speaking her own words.

"I could walk her into a coffee shop, have a conversation, and no one would suspect anything. Her own mother wouldn't know the difference."

Ashley laughs—bright and girlish—then poses before the mirror, hands on hips, examining herself from different angles. The behavior of someone admiring their reflection—except the person admiring is the aging scientist beside you.

"She can't feel this. There's no 'her' in there. When I disconnect, she wakes up with a gap she can't explain."

He taps 'DISCONNECT.'

Ashley twitches, blinks rapidly. Confusion blooms across her face—real this time. She looks around, touches her loose hair with visible bewilderment, finds herself standing when she'd been sitting. After a moment, she shakes her head, retrieves her hair tie, and returns to the couch, scrolling her phone with a furrowed brow.

"No trauma. No memory. Just a gap she'll rationalize away within minutes." Dr. Vance sets a case on the table—earpiece, fresh sweatband. "Your tester kit."

He watches Ashley through the glass, that unsettling smile spreading.

"The learning curve is steep. You'll spend early sessions just lifting a hand without lifting your own. But once their body feels as natural as yours?" He chuckles. "You'll understand why I've kept Ashley around for three years of 'audio testing.'"

The laboratory is dark except for the pale glow of emergency exit signs and the faint blue pulse of equipment on standby. You move through the shadows alongside Roland—lanky, dark-haired, insufferably cocky even when whispering. He's been your partner on a dozen jobs, and his lockpicking got you through three doors to reach this basement level.

"Jackpot," Roland mutters, shining his penlight across a cluttered desk. His beam lands on a small case, a tablet, and what appears to be a gray athletic sweatband. "The hell is this stuff?"

You examine the case. Inside, a slot clearly meant for an earbud—empty. The tablet screen illuminates at Roland's touch, displaying an app interface with one paired device listed: "ASHLEY-R-EAR - CONNECTED (STANDBY)."

"Some kind of Bluetooth thing." Roland picks up the sweatband, turning it over. "Weird. Sensors on the inside."

He pulls it onto his forehead with a grin, striking a pose.

"How do I look? Very tech-chic, right?"

Before you can respond, footsteps echo in the corridor. You both freeze. The door handle turns.

A young woman enters, fumbling for the light switch—early twenties, honey-blonde hair loose around her shoulders, wearing a university hoodie and jeans. An intern badge dangles from her pocket. She's clearly here after something forgotten, keys in one hand, phone flashlight in the other. She hasn't spotted you yet in the dark corner, but she's about to.

"Shit shit shit—" Roland panics, grabbing the tablet. His thumb jabs randomly at the screen.

The app flashes: CONNECTION ACTIVE.

The woman freezes mid-step. Not startled—frozen. Her phone clatters to the floor, flashlight spinning. Her body locks in place, one foot forward, arms slack, head tilted slightly. Eyes open. Completely vacant.

Roland stares, eyes wide, mouth hanging open in shock. Across the room, the woman's face shifts into the exact same expression—eyes wide, mouth hanging open, mirroring his shock on her pretty features. It looks deeply wrong, her youthful face wearing his panic.

He takes a step backward—and she takes a step backward, perfectly synchronized. Same leg, same angle, same slight stumble. His brow furrows in confusion; her brow furrows identically.

Roland raises his hand slowly. So does she. He turns his head left. So does she. His face cycles through rapid confusion—frown, squint, parted lips—and hers follows every micro-expression in perfect mirror, a beautiful young woman wearing a lanky thief's facial tics.

"What the fuck—"

"What the fuck—" Her voice emerges simultaneously, identical words in a young woman's pitch, her lips moving in perfect sync with his. Her face twists into his grimace of horror.

"Oh my god. Oh my god oh my god—"

"Oh my god. Oh my god oh my god—" She echoes, her delicate features scrunched into Roland's panicked expression—teeth bared, eyes darting, nostrils flared. On her face, his fear looks almost comical.

"Stop copying me!"

"Stop copying me!" Her voice overlaps with his, her face contorting through his frustration—jaw clenched, eyes squeezed shut, then snapping open.

Roland clamps his mouth shut, forces his face neutral. She goes silent, her expression smoothing to match—but there's a delay, a stutter, her features settling into blankness a half-second after his.

He stares at her for a long moment. Then, slowly, a grin spreads across his face—boyish, mischievous. The same grin spreads across hers, looking strange on her delicate features.

"Wait. So whatever I do..."

"Wait. So whatever I do..." Her voice overlaps perfectly, her face wearing his dawning realization.

Roland glances down at his flat chest, then across at her. The university hoodie she's wearing is loose, but there's an obvious curve beneath it. His grin widens. So does hers.

His hands come up to his own chest, cupping where breasts would be if he had them. His palms press against his flat, bony sternum—but across the room, her hands mirror the motion exactly, rising to cup her breasts through the hoodie. Her fingers squeeze where his squeeze, press where his press. She's groping herself with his movements, her vacant face still wearing his stupid grin.

"Holy shit," Roland breathes, squeezing experimentally. She squeezes. He watches, transfixed, as her hands knead her own chest in perfect sync with his—except she's actually got something to grab. "Holy shit, dude. Look at this."

"Holy shit," she echoes in her feminine voice, his awed expression on her face. "Holy shit, dude. Look at this."

He bounces on his heels a little. She bounces too, and there's visible movement under the hoodie. His eyes go wide—hers mirror the expression while her hands continue copying his self-groping.

"I can't feel it," he mutters, disappointed, still squeezing. "Like, I can see her doing it, but I don't feel anything."

"I can't feel it," she parrots, her face falling into his disappointment even as her hands grope her own tits. "Like, I can see her doing it, but I don't feel anything."

He drops his hands. Hers drop too. He looks at you, that mischievous grin returning—and her face mirrors it, making the pretty intern look impish and devious.

You grab the tablet. The screen displays instructions—a quick-start guide:

BASIC OPERATION: Neural impulses transmit to paired device. Movement intention routes to connected body. Initial users experience mirrored output—practice isolating focus to single-body control. Close eyes to access subject's vision (concentration required).

Roland reads over your shoulder, his eyebrows rising—and across the room, her eyebrows rise too. He winces at the sight; she winces.

"This is so fucked," he whispers, and her lips move with his, her face wearing his disturbed grimace. "She's doing everything I do. Even my face. Look at her."

He experimentally raises one eyebrow. She raises one eyebrow—his skeptical expression transplanted onto her pretty features.

More text on the tablet:

TIP: Visualize the connected body as separate. Imagine moving "that" body, not "your" body. Sensation of phantom limb may develop with practice. Expect initial difficulty—mirrored impulses are normal for beginners.

Roland takes a breath, trying to compose himself. His face relaxes slightly—and so does hers, though she still wears a ghost of his tense jaw.

"Okay. Okay." He speaks slowly, concentrating. His mouth moves—and hers moves too, but sluggishly, out of sync, like a bad dub. "I think I can... separate it..."

He focuses. Her arm rises slowly, jerkily, like a marionette with an amateur puppeteer. His own arm twitches but stays mostly down. Progress. His face shows concentration—furrowed brow, pressed lips—and hers starts to mirror it, then stalls, her expression going slack as he focuses on keeping her face neutral.

"Holy shit." His voice alone this time. His face shows amazement—but hers remains blank, empty. "I did it. Her face isn't copying me."

He grins triumphantly. Her face stays slack for a moment—then the corner of her mouth twitches upward, fighting his grin bleeding through. He notices and forces his expression neutral; hers smooths out again.

"It's hard. It keeps leaking." He's speaking through clenched teeth now, trying not to emote. Her face twitches with micro-expressions he can't fully suppress—a flicker of his frustration around her eyes, a ghost of his concentration in her brow.

Her body takes a stumbling step forward. Then another. The movements are awkward, uncoordinated—a person learning to walk for the first time. Roland's own legs shift in micro-movements he can't quite suppress, his body wanting to mirror what he's making hers do. His face twitches with effort; hers flickers with shadows of the same strain before going slack again.

The tablet screen shows: ASHLEY M. - NEUROLOGY INTERN.

Ashley stands in the middle of the laboratory, body slack and waiting, face empty—mostly. Occasionally a flicker of Roland's emotions ghosts across her features before he catches himself: a twitch of his nervous frown, a flash of his wide-eyed disbelief.

Roland looks at you, face carefully controlled—and across the room, Ashley's face stays blank, only the faintest echo of his expression leaking through around her eyes.

"...What do we do with her?"

The laboratory is quiet save for the hum of equipment. Dr. Emil Vance leans back in his chair, that crooked smile of his wider than usual. On the desk between you sits a small cupcake with a single lit candle, its glow flickering across the cluttered workspace.

"Happy birthday," he says, gesturing vaguely at the cupcake. "Blow it out. Make a wish. Whatever."

You oblige. He watches with amusement as the candle goes dark.

"Two years you've been helping me with this project. Never complained, never asked for anything." He drums his fingers on the desk. "Figured it was time I gave you something special."

He taps his tablet. The door opens and Ashley walks in—honey-blonde hair in its usual ponytail, fitted blouse and skirt, bright-eyed and cheerful.

"Hi! Dr. Vance said you needed me for another calibration test?" She glances at the cupcake, then at you, smiling warmly. "Oh, happy birthday! I didn't know!"

"Thank you, Ashley. Yes, just a quick calibration. Stand right there."

She stops in the middle of the room, hands clasped in front of her, eager to help. Dr. Vance pulls on his headband, not bothering to hide it. Ashley doesn't know what it does—just assumes it's more equipment.

"Ready when you are, Dr. Vance!"

He taps 'CONNECT.'

Ashley freezes mid-smile. Her hands drop to her sides, her bright expression sliding into vacancy. Eyes open, empty. Body still. That familiar powered-down look—a machine awaiting input.

Dr. Vance closes his eyes briefly, settling in. Then Ashley moves.

Her posture shifts, shoulders rolling back, head tilting with a deliberateness that doesn't match the bubbly intern. Her vacant eyes gain focus—but something behind them is wrong. She looks down at herself, then up at you, and smiles. It's Ashley's face, but the expression belongs entirely to the man sitting three feet away.

"There we go." Ashley's voice, Vance's cadence. Her hands smooth down the front of her blouse. "All yours for the evening."

She reaches up and pulls the hair tie from her ponytail, shaking blonde waves loose over her shoulders. Her fingers card through the strands slowly, arranging them.

"I know her body better than she does at this point." Ashley's hands settle on her hips, turning slightly to present herself. "Three years of practice. I can make her do anything you want—and do it well."

Dr. Vance's own body sits motionless in his chair, eyes closed, a small smile on his face. Ashley's borrowed body stands before you, that knowing expression waiting.

"So. What would the birthday boy like?"

Valentina's lips taste like the strawberry chapstick she always wears. You know this because you've tasted it dozens of times over the past few months—through your own lips pressed against hers, piloting her body to kiss yourself with exactly the pressure and rhythm you want. Her eyes are closed because you're keeping them closed, her hands tangled in your hair because you put them there, her soft moan muffled against your mouth because you made her moan.

Your own eyes are closed too, focused on seeing through hers—the dim apartment living room from her perspective, your own face filling her vision whenever you let her lids flutter open. The phantom sense is strong now. You know the weight of her curves, the way her full hips shift when you move her, exactly how much pressure to use when you make her grip your shoulders. Three months of practice and Valentina's body fits like a glove.

She's straddling your lap on the couch, her thick thighs bracketing yours, that tight tank top she wears around the apartment riding up to expose a strip of brown midriff. You're making her grind slowly, rolling her hips in a lazy rhythm while her mouth works against yours. Her long dark hair—loose, because you took it out of its ponytail when you connected—curtains around both your faces.

The TV plays some reality show neither of you are watching. Background noise. Alibi.

You hear the key in the lock.

Your eyes snap open. Valentina's body freezes mid-grind—and this time it's intentional, controlled, not the panicked lock-up of a beginner. You've done this before. You're good at this.

Two seconds. Maybe three.

You slide Valentina off your lap and onto the couch beside you in one smooth motion—her body compliant, effortless to move, settling into the cushions exactly where you place her. Her tank top gets tugged down. Her hair gets swept back over one shoulder. Her posture shifts to casual, leaning back, one leg tucked under her. You make her grab the remote from the coffee table and point it at the TV, flicking up the volume two notches.

Your own body mirrors none of it. You're already slouched in your original position, arm draped across the back of the couch, eyes on the screen. Relaxed. Bored. Just two roommates watching TV on a weeknight.

The door swings open and Marco walks in—tall, gym-built, handsome in that effortless way that always made you a little jealous. Valentina's boyfriend of two years. He's carrying takeout bags and wearing that easy grin of his.

"Hey babe! Got Thai." He kicks the door shut behind him, glancing between you and Valentina on the couch. "What're you guys watching?"
