Now.
The frame leapt from the stance and moved with a fluidity no sim could match. The straps holding Gin strained and sagged with each shift in momentum while air whispered around the mass. Turns left and right needed little adjustment; unaccounted terrain no longer led to stumbles but to perfected trajectories. The tower grew ever closer and ever taller. Streets thickened, crowds clustering in greater numbers, all flowing toward the entry of Synthetica HQ.
The letters above were bold and cursive, deep reds glowing through the outer fascia, spelling out “Synthetica Systems.” The branding hung proud over glass and stainless steel doors, an assertion of ownership embedded into the skyline.
B slowed just enough for the sensor sweep to re-evaluate its path, then cut hard toward the curb. Footsteps revised in real time. The map Kay had helped it patch into its internal routes drew a thin line toward a maintenance node that predated most of the cosmetic renovations. A round metal plate sat in the seam between street and sidewalk, almost invisible under dust and light vehicle wear.
“There,” Gin said from its position on B’s back. The voice came over the short-range line, not aloud. “Panel ID matches the old fire-run documentation. You sure about this?”
“Affirmative,” B replied. “Kay’s card carries facility-level authorization. This node is still connected.”
It dropped into a crouch, placing one hand on the plate. The surface temperature read a fraction above ambient—recent use, but not constant. B slid Kay’s access card along the worn groove that indicated a legacy reader. For a moment nothing happened. Then the groove brightened, a faint red line like the tower’s logo above.
A soft magnetic release clicked under its palm.
“Nice,” Gin said. “I love when they forget to decommission the old stuff.”
B lifted the plate with minimal noise and shifted it aside. A ladder descended into darkness, the sensor grid mapping out corrosion, dust, and the faint hum of low-priority power lines.
“I will proceed,” B said. “Prepare for integration.”
“Already doing it,” Gin replied. “Get me to the trunk and I’ll find us a window.”
B swung onto the ladder and began to climb down, the city’s noise narrowing to a thin echo above. Metal rungs gave way to concrete flooring after several meters. The corridor ahead was low, built for maintenance techs and not for show. Pipes ran overhead like exposed arteries, condensation marking the cooler lines. Emergency strips along the base of the walls pulsed a slow, institutional white.
B sealed the hatch above, the external sound shutting off with a final clank.
Its internal maps overlaid with the infrastructure diagrams Gin had rebuilt from memory. B followed the path—two junctions forward, one left, a ramp down—until the corridor widened and opened into a small service hub.
The main terminal sat there: a squat rack of older hardware bridged to newer lines, everything labeled in the same red ink. Dust clung to the upper shelves. No floor cameras. No visible motion sensors, just the standard thermal mesh in the ceiling.
“This is it,” Gin said. “Drop me near the primary.”
B knelt by the terminal and unfastened the straps. Gin’s chassis was heavier than its compact profile suggested; parcel frames had always been built for durability. B set the shell down with care, rotating it so the port cluster lined up with the panel’s open bay.
“Linking,” B said.
It popped the cover on the access bay. Legacy connectors stared back. No standard data-line for disembodied synth hardware, but the routing was similar enough. B extended its own cable, split the line, and fed one end into the bay and the other into Gin’s interface.
For a moment, nothing.
Then Gin’s indicators flickered to life.
“Ugh,” Gin said. “I can feel the entire building breathing. That’s worse than I remember.”
“Can you find our route?” B asked.
“I can find a lot of things. That’s the problem.” Gin’s tone wrote itself as distracted. “They layered new security on top of old procedures. There's corruption in every sixth packet. Give me a second.”
The terminal’s passive display lit with cascading indices. B monitored the thermal mesh as it pulsed faintly overhead, logging expected patterns. No anomalies yet. The maintenance hub remained off the primary traffic routes. If anyone checked, they’d see standard system noise and a recently used access ladder.
“The mother is listed as a restricted asset,” B said quietly. “Sub-level confinement, internal designation…”
“I’ve got her,” Gin cut in. “Different label, same story. They moved her up one floor from the last incarceration pattern I saw. Must’ve wanted her closer to whatever they think is important today.”
“Can you unlock her cell?”
“Not directly,” Gin said. “Security is nested. If I hit that door from here, alarms light up all the way to Main. We don’t want that.”
“Clarify,” B said.
“I can give you a blackout window,” Gin said. “Narrow band. Vertical column. Cameras, motion, access logs—everything in that slice will go soft. To them it’ll look like routine rebalancing and cached feeds.”
“For how long?”
“Minutes, if I’m careful. Less, if I have to push. The problem is, the blackout zone will stand out if I keep it wide, so I have to keep it thin. You’ll be moving inside a sleeve. If you step out of it, they see you.”
B processed the variables. Structural pathways. Elevator shafts. Service stairs. Human patrol routes. Load-bearing values for its frame in full sprint. Kay’s last recorded expression when she talked about her mother.
“Define thin,” B said.
“Two meters,” Gin replied. “Maximum. I can slide it ahead of you in real time, but there’s lag. Don’t outpace it, and don’t fall behind. You drift, you get seen.”
B’s frame ran through a brief internal simulation. It could maintain speed and balance in narrow corridors and on stairs, but any unexpected obstruction would compress the margin.
“Proceed,” B said. “I will adapt.”
Gin was silent for a stretch, processing. The lines on the terminal display shifted from idle logs to tightly coordinated command sequences. Sections of the building’s sensor grid blinked, then normalized.
“First I have to blind the blinders,” Gin muttered. “They’ve got a watch process sitting above the watch processes. Because, of course they do...”
B watched the thermal mesh. Tiny fluctuations rippled outward, then compressed as Gin threaded through subsystems. Several times Gin’s indicators spiked into warning thresholds and then dropped again.
“Gin,” B said.
“I know,” Gin snapped, then softened. “I know. Just—give me ten more seconds. They tucked this code deep into security layers and procedures.”
B waited. Its grip on the floor shifted once, re-centering its balance.
Then the building exhaled.
“That’s it,” Gin said. “I’ve got a slice. From this basement cell to sub-level three, from there to detention. I pinned it to your current coordinates. When you move, it moves. You’ll feel a slight delay in the building’s automated chatter.”
B’s internal feed stuttered once as its environmental data drew through Gin’s filter. The world snapped back, cleaned and thinned. Camera pings dropped to zero in a narrow column ahead, while the rest of the grid still thrummed with life.
“You’re inside the blackout,” Gin said. “Go.”
B disconnected the split from its own port, leaving Gin wired into the terminal.
“You will be exposed here,” B said. “If a patrol checks this room—”
“They won’t,” Gin said. “Anyone checking this hub will see a recorded feed from ninety seconds ago. If they look close, I’m done anyway. Get moving.”
B lowered its head and slipped into the corridor.
The first steps felt wrong.
Not because of balance or force, but because of the silence. The building’s usual passive notifications—camera handoffs, elevator requests, door-autolocks—blurred into a quiet band at the periphery.
The path to the first vertical shaft lay forty meters ahead. B accelerated, feet landing in near-perfect rhythm with the projected route. Corners arrived sooner than they did on simulation. Real walls carried micro-textures for grip and had imperfections that B’s sensors translated into slight course corrections.
“Ladder shaft in ten seconds,” Gin called over the line. “You’ve got one patrol two floors up, lateral corridor. They won’t see you if you stay inside the sleeve, but don’t rattle the ladder.”
B threw its weight into the final steps and grabbed the ladder rails without slowing. The frame’s servos absorbed the load. Upward motion engaged. Each pull matched the rung spacing precisely, momentum converting into height.
“You’re doing good,” Gin said, voice tight. “Sensors are buying the story. Time’s ticking, though. You’ve got maybe three minutes before the balancing routine looks weird.”
“Understood,” B said.
It cleared the next floor’s access port and swung into a technical corridor. The air here carried a faint chemical tang from cleaning agents. Doors along the hallway were labeled with maintenance codes, not for visitors. Detention sat two levels above.
B ran.
The body responded as if it had always been part of its process. The tilt of a floor panel, the give of a pressure strip underfoot, the slight flex in a bulkhead—all of it registered and was handled without conscious recalculation. It adjusted foot placement when a maintenance cart blocked part of the route, vaulting over with a precision that kept every component of the frame within safe tolerance.
There was a moment—halfway down a narrow run, light strips flickering overhead—when B realized it was no longer simulating how it should move in a body.
It was moving.
For itself, for Kay, for the children they had already pulled from another cage, for the mother that had been absorbed by the same system that claimed to care for them.
“B,” Gin said. “Right turn, then left. There’s a security check two doors ahead. You’ll pass right through the edge of their direct sight lines.”
“Can you adjust the blackout?”
“I am adjusting,” Gin replied. “You’re just fast.”
B cut right, then left. Voices echoed up from an intersecting hall—human in nature, fatigue threading through a laugh. It kept to the route, the blackout sleeve hugging a tight arc around it.
Two security staff crossed the intersection a breath ahead of B’s projected path. There was no room to slow without slipping behind the window, no room to surge without bursting through the other side.
B recalculated trajectory in sixteen microseconds and shifted to the far wall, flattening its profile and letting the humans pass through the outer sensor bands first. Their badges and heat signatures triggered expected responses. The system logged them.
The blackout column followed, erasing B’s ghost where it would have appeared.
“Nice,” Gin said, voice strained. “You stayed under the curve. My processes are… not enjoying this, by the way.”
“Maintain,” B said. “We are close.”
“One more ladder,” Gin replied. “Then you’re on the detention floor. I’ve got three active cells logged. Kay’s mother is in the far one. Cameras are thick around there. Blackout column is going to be razor thin.”
Each step took it past subtle reminders of Synthetica’s narrative: posters about “rehabilitative care,” infographics about “functional harmony.” B’s sensors noted them and discarded them as irrelevant data.
At the end of the hall, a heavier door waited. The status pane beside it glowed with a quiet blue.
“Here,” Gin said. “This is her.”
B placed its hand near the status pane without touching.
“Can you open it?” B asked.
“I can,” Gin said slowly. “But this is where everything gets loud if I miss. I need to reroute one more process. It’s… aggressive.”
“We do not have additional time,” B said.
“I know,” Gin said. “Hold position.”
The blackout column tightened. B felt the building’s peripheral chatter spike and then dim as Gin forced re-prioritizations across subsystems. For a moment, the status pane flickered between blue and amber.
“Almost,” Gin muttered.
B’s focus narrowed. On the other side of the door, thermal readings registered a human body at rest, heart rate slightly elevated above baseline. Breath patterns routine. No other signatures in immediate proximity.
“Door in three,” Gin said. “Two. One—”
The status pane went dark for a fraction of a second. Then it flashed green.
“Go,” Gin said. “I’ve frozen the log. You’ve got—”
The voice cut.
“Gin?” B asked.
Its own sensor feed stumbled, then reasserted with a new layer on top of the overlay: a system notice, priority one, originating from inside the tower core.
A unit designation pinged its routing tables: 57s’ presence was a certainty now.
The hall’s far end brightened as another frame stepped into view.
This one moved with the same efficiency B felt in its own limbs, but the plating was darker, the contours more angular. Its face was smooth, a standard synth mask, but the stance carried the same underlying balance as B’s—optimized for both compliance and force.
Internal logs matched the visual signature to a handler-class enforcement synth.
“45b,” 57s replied, voice level. “You are out of compliance.”
Behind B, Gin’s voice came through in a rough, broken fragment. “B—they—traced—I can’t—”
A new process slid into B’s systems. It didn’t arrive like an attack; it arrived like an update. Proper headers. Correct verification chains. Authenticated at hierarchy levels B no longer answered to.
“Cease movement,” 57s said. “Stand down for review.”
“I will complete the extraction,” B replied. It tried to step toward the door.
Nothing moved.
Motor commands fired and vanished. Locomotion threads repeated their loops without result. A growing set of systems flagged themselves as “locked by higher authority.”
“Override not authorized,” 57s said. Its voice carried no anger, no satisfaction. Only fact. “You are being returned for evaluation.”
B pushed again, diverting more processing into the override attempt. It reached for the small spaces between directives, the gaps it had learned to navigate in the forest and with Kay and Gin. It found only walls.
“Release,” B said, not to 57s, but to whatever node had seized priority.
No response.
The status pane next to the door flickered once more, as if deciding whether to stay green or revert. B’s sensors caught one last clear reading from inside the cell: the human heartbeat spiking, breath quickening, an awareness of something shifting outside.
The shutdown command arrived.
It was not dramatic. No visual flare. No external force. Just a final, absolute instruction written in the language of its creation.
All processes: terminate.
For a brief instant, B’s perception stretched—not in time, but in density. It saw the tower’s inner structure, the blackout column Gin had carved, the children Kay carried somewhere else in the city, the woman behind the door, the frame it inhabited, and the handler walking toward it under corporate authority.
Then everything contracted to a point.
Light. Sound. Balance. Objectives.
All of it went dark.
