Chapter 28 – Default Route
The track took the carrier frame before Kai could brace.
The floor pulled him through the split wall and into the narrow passage. Metal drawers slid past on both sides, close enough to scrape his hands if the frame shifted. The ceiling dropped lower after the first turn. Nia had to duck and run sideways with one hand on the rail.
The lunch box bumped against her ribs.
The E key flashed between her fingers.
The proof tube rolled behind them along the track, tapping softly each time it crossed a seam.
Kai tried to twist enough to see the doorway they had left. The waist rail stopped him. His bad foot dragged against the footrest until Nia noticed and kicked it back into place without slowing.
"Don't lose your foot," she said.
"I am trying to keep the rest of me."
"Do that too."
The passage answered with three clicks ahead.
Not a knock from a person.
Not a fist.
A mechanism, small and regular, working somewhere inside the drawers.
The wall glass above the left row woke as the carrier passed beneath it.
DEFAULT ROUTE
Unheld proof in transit
Carrier retained
External collection contest pending
Nia read while running. "Default route means what?"
"It means no one made a clean choice."
"That doesn't answer me."
"It means we don't get to choose."
The collector's voice came from behind them, still using Derek's voice.
"Carrier entry required."
The passage was too narrow for the thing to walk through. That did not stop the red strings.
They slid around the open wall and entered the passage in thin lines, crawling over the track and along the drawer handles. One string touched the floor where Kai's frame had been a second earlier. The metal hissed.
Nia saw it and ran faster.
The frame kept its pace.
Kai looked down the rail. "If the strings reach the tube, kick it forward."
"With what free leg?"
"Then warn me before it touches."
She gave him one sharp look.
He shut up.
The tube tapped another seam and rolled uphill.
That made Nia look back.
The passage dipped slightly toward Bay 3. The tube should have rolled away from them. It did not. It climbed the track in short, patient movements, following the carrier frame.
The lunch box clicked against Nia's side.
Kai's dead left hand jerked once.
He watched the fingers hit the rail. He still could not feel them.
"Keep the box away from it," he said.
Nia shifted the lunch box higher under her arm. The lid was still open by a finger's width. A pale line shone between the metal edges.
"It is not trying to touch the box," she said.
The tube rolled another inch toward them.
The pale line in the lunch box bent toward it.
"It is," Kai said.
The first red string reached the tube.
Nia swore, bent, and hooked the old envelope around the tube without touching the glass. The string touched the envelope instead. The paper went gray at the corner and split like old ash.
She kicked the tube ahead of the carrier frame.
It rolled forward, bounced off the left rail, and kept pace with them.
The wall glass changed.
External collection request received
Proof may be surrendered
Carrier may be surrendered
"No," Kai said.
Nia did not ask which line he meant. "Wasn't planning to."
The passage narrowed again.
Drawer handles passed close to Nia's shoulder. She turned sideways, one hand on the carrier rail, one arm clamped around the lunch box, E key trapped between two fingers. Her breathing had gone rough, but her eyes stayed on the floor ahead.
Kai could do nothing about the track.
That was the worst part. Not the pain in his foot. Not the numbness in his hands. The frame moved him at a steady pace, like it was taking him back to storage.
He pushed his right forearm against the waist rail. The ticket under his skin warmed.
No status window opened.
No class prompt noticed him.
Only the passage kept filing him.
A drawer shot out from the right wall.
Nia almost ran into it.
The carrier frame stopped so hard Kai's ribs hit the rail. His breath left in a short grunt. The tube rolled up beside the locked front wheel and rested against it.
The drawer was shallow, no deeper than a lunch tray. It had a rubber-lined cradle inside and a round key slot under the handle.
Printed letters glowed on the glass above it.
PLACE PROOF FOR RETURN
Nia stared at the tray. "Return where?"
The glass did not answer.
The red strings behind them kept coming.
Kai could hear them now, a thin scrape along the drawer handles.
"It wants the tube," he said.
"This is the only thing that looked like proof."
"It also tried to make you the holder."
"And then it tried you."
"Yes."
Nia looked down at the tube by the wheel. The paper bracelet inside had folded back into a tight white loop. The yellow button rested against the glass, face turned outward, cheerful and wrong under the passage light.
The lunch box clicked again.
Kai's left hand lifted half an inch from the rail.
Nia stepped back.
The hand dropped.
The glass added another line.
Unreturned proof defaults to carrier
The red strings came around the last bend.
Nia looked from the tray to the tube, then to the red strings. She was counting time now.
"If I put it there," she said, "we lose it."
"If you keep it, it chooses a holder."
"You."
"Maybe."
"Don't make that sound acceptable."
"I'm not."
The carrier frame jerked forward against the locked wheel. Metal groaned. Kai's stomach pressed into the rail until he tasted copper.
The wall printed again.
Carrier resonance increasing
Proof return pending
Nia crouched, used the torn envelope to scoop the tube, and set it into the tray.
The cradle lit white.
The tube did not release.
A pale line stretched from the tube to the lunch box.
Nia moved the box away.
The line stretched with it.
Kai's left hand rose again.
This time the fingers curled.
He still felt nothing in them. The movement started at his wrist and pulled up through his forearm into the shoulder, where feeling returned as pain.
The tray clicked twice and refused to close.
Holder residue detected
Manual separation required
Nia found the key slot under the tray. "E key?"
"Careful."
"That has become a useless word."
She fitted the E key into the round slot.
It turned halfway and stopped.
The cracked route token in her hand warmed red.
Nia looked at it.
Kai saw the answer before the wall gave it.
Route token required
Nia's jaw tightened.
"No," Kai said.
"You don't know what it costs."
"Neither do you."
"I know what happens if I don't."
The red strings reached the rear of the carrier frame.
One touched the back wheel.
The wheel smoked.
Kai's right hand clenched on the rail. He felt the ticket twist under his skin.
The collector spoke from the bend behind them.
"Carrier may be surrendered."
Nia shoved the cracked route token into the narrow slot beside the key before Kai could stop her.
The red arrow on the token split down the black crack.
The passage lights dimmed.
The tray pulled at the tube.
The pale line from the tube to the lunch box tightened. Nia stumbled forward. The lunch box lid opened another inch, and the cold light inside touched Kai's neck.
His dead hand snapped toward the tray.
The fingers caught the edge.
For one second, the carrier frame, the tube, the lunch box, and Kai's arm all pulled in different directions.
Pain climbed from his shoulder into his jaw.
Not feeling.
Pressure.
Pressure pushed through his arm until his shoulder felt ready to tear.
Kai forced his breath down.
It was not the clean breathing his grandfather had taught him. It was the breath he had used beside the first monster core, ugly and uneven, forced through pain.
The first meridian under his ribs answered with heat.
The heat did not help.
It showed him where the pull was.
White thread from tube to lunch box.
Black pressure from lunch box to wrist.
Red claim from the collector touching the back wheel.
None of it belonged to him.
Because none of the pulls belonged to him, he could push against them.
Kai opened his right hand and pressed the marked palm flat against the waist rail.
The half ticket under his skin burned.
"Nia," he said through his teeth. "Close the box."
"My hands are full."
"Use the key."
She understood too fast to ask.
Nia left the E key turned in the tray slot, grabbed the lunch box with both hands, and drove the key ring against the lid. The metal rang. The lid snapped down to a finger's width, not closed, but enough.
The white thread thinned.
Kai dragged his breath lower.
His left hand opened.
He saw it happen.
He did not feel it.
The tube dropped fully into the tray.
The drawer slammed shut.
The red string on the back wheel snapped and hissed against the rail.
Nia ripped the E key free.
The cracked route token did not come with it.
She stared at the empty slot.
"Leave it," Kai said.
"That was our route."
"It was also their hook."
Her grip tightened on the key.
The wall glass printed three lines.
Proof return accepted
Carrier resonance reduced
Default route continues
The tray slot spat out a strip of paper.
Nia caught it before it hit the floor.
This one was narrower than the white proof strip. The paper was stiff, gray at the edges, and warm enough that she shifted it between her fingers.
Kai read what he could as the track unlocked.
RETURN RECEIPT
Article sealed
Dependent condition unreleased
Carrier substitution attempted
Manual separation recorded
Nia folded it once and tucked it behind the first white strip.
"It still says condition unreleased," Kai said.
"I saw."
"That means it did not answer."
"I saw."
Her voice was flat. He did not push.
The carrier frame lurched forward again.
The passage changed after the tray.
The drawers were smaller here. Some had colored stickers under the handles: suns, moons, and cartoon shapes Kai did not recognize. Several had empty hooks where bags or coats had been removed. Most labels showed only route numbers and dates.
Nia slowed enough to look at one.
Kai caught the route number.
6-C
The drawer knocked as they passed.
Then the next drawer knocked.
Then the next.
The sound moved ahead of them, drawer by drawer, down the passage.
Nia kept her eyes forward. "Do not tell me those are people."
"I won't."
"Is that because they are not?"
"It is because I don't know."
Nia's mouth tightened. She kept moving.
The collector's red strings did not disappear. They followed farther back now, slower after the broken line, testing the walls and rail with small hisses.
The voice came again, quieter.
"Carrier has reduced proof value."
The wall answered before Kai could.
Carrier remains disputed
Manual claim window ahead
Nia looked at the new line. "Manual claim?"
"That sounds like a place where it asks you to make a mistake."
"It also sounds like a place with answers."
"Those can be the same place."
The track bent left.
The passage opened into a room too small to deserve the word. It was a booth, built into the end of the drawer corridor. The carrier track ran straight into a floor lock before a glass window. On Nia's side, there was barely room to stand.
A stool had been bolted to the floor in front of the window.
It was child-height.
Nia stopped beside it.
Kai's frame rolled into the lock and clicked down.
This time the rail around his waist tightened before he could inhale.
The lunch box clicked once under Nia's arm.
The E key shook in her hand.
Behind the glass, a metal shutter waited. A chain hung beside it, attached to a pen with no ink visible in the tip.
Above the shutter, black letters appeared one at a time.
MANUAL CLAIM WINDOW 6
One question may be entered
Condition answers restricted
False relation assigns carrier
Nia did not move.
Kai looked at the child-height stool. Then at the pen.
"Don't sit," he said.
"I wasn't going to."
The shutter knocked.
Once.
Twice.
Three times.
The pen chain dragged across the counter by itself, link by link, until the pen hung over the blank card beneath the glass.
The card slid out far enough for a hand to reach.
Nia stared at it.
The first white proof strip and the gray return receipt were folded together in her fingers. The lunch box lid trembled against her arm.
Behind them, the red strings turned the corner.
The glass changed again.
Write the question.
Kai felt his marked right hand go cold.
The pen tip lowered by itself and touched the card.
It began to write the first letter of Elise's name.
