On the walk home, Mara found Evelyn waiting on her porch with a bucket, rags, and a bottle of paint-safe solvent.
“I’d like to try removing the pink,” Evelyn said.
“It’s dry.”
“I brought patience.”
Mara handed her gloves. They worked beneath a porch lamp, carefully testing the siding before scrubbing each painted patch. The camera housing was beyond saving, but the siding slowly returned to white. For a while they spoke only about whether the solvent was doing more harm than good.
Then Evelyn said, “I thought Julian had convinced the street you were spying on people. That’s how he described you to me.”
“I pointed the camera at my driveway because somebody kept leaving broken glass behind my car.”
“Did you find out who?”
“An overloaded recycling truck. Not exactly an international conspiracy.”
Evelyn let out an embarrassed breath. “He told me it watched his crews.”
“It probably did. They park in front of my house. But I wasn’t monitoring them.”
“He said he could use it to make it look as if I threatened his workers.”
“That’s why you sprayed it?”
“In part.” Evelyn scraped a patch of paint. “I was furious. That was the other part. I wanted to damage something that made me feel watched and powerless.”
“Thank you for saying that.”
“Don’t thank me. I’m not proud of it.”
Mara rinsed her cloth. “The blue key frightened you more than getting caught.”
“Yes.”
“Why?”
“Peter asked me to keep it after the accident. He said the key should have stopped everything. I couldn’t bear to look at it. I gave it to Gabriel with the rest of the controller pieces, and then spent years remembering things the wrong way.”
Mara leaned the scrub brush against the railing. “You never blamed Peter, did you?”
“I blamed us both. We invited children into a machine we didn’t understand completely.”
“Maybe the part you didn’t understand was someone else’s addition.”
“Maybe. That doesn’t erase our responsibility.”
They worked until most of the pink was gone. A narrow stain remained beneath the eave, visible only if one knew where to look. Evelyn promised to pay for a replacement camera and left the red ladder as collateral, insisting Mara keep it until she made good.
The following day would decide whether the Lantern Walk happened at all.
Mara went to bed thinking about the external input and its twelve-petal pattern. Somewhere between sleep and waking she remembered a fact she’d overlooked: in Evelyn’s childhood drawings, the Glass Garden had twelve petals, but the floor in the gym had only eleven working sections.
She sat up.
One petal was missing.

Mara arrived at the school at seven the next morning. The gym doors were locked, but through a narrow window she could see the covered platform. She sketched the pattern from memory on the back of a coffee receipt: twelve petals around a central hub, eleven responding motor groups, and one blank arc near the eastern edge.
If the controller sent a twelve-part command to an eleven-part mechanism, its behavior depended entirely on how the missing channel had been handled. A responsible redesign would remove that channel from the program. An impatient one might bridge it to the nearest motor, doubling the load and making one corner leap.
Leon arrived on his bicycle, breathing hard from the hill.
“Ellis was here at six,” he said. “He asked the custodians to unlock the gym, but they wouldn’t without the principal. Julian drove him away.”
“Did you see what they were carrying?”
“A wooden crate marked P12.”
“Petal twelve,” Mara said.
“Is that bad?”
“I don’t know yet. That’s what makes it dangerous.”
She called Evelyn. The older woman listened to the sketch’s description and surprised Mara with a laugh.
“Of course,” Evelyn said. “Peter removed the twelfth petal before the final rehearsal. The loading ramp couldn’t fit it. It was too wide for the hall.”
“Then it was never installed?”
“Not during public shows.”
“What did Peter do with its control channel?”
“Put a dummy load in its place. A big bank of resistors. It made the controller think there was another motor, without moving anything.”
“Where is that dummy load?”
“Last I saw, in a metal box under the stage.”
Mara imagined the fresh brackets and new motor housings she’d seen. “Suppose someone removed it.”
“Then the controller should warn them.”
“Unless they tied that channel to another motor.”
Evelyn went silent. “That would be foolish.”
“Would it be enough to explain the jump?”
“It could explain one jump. Not the cascade from fourteen years ago.”
“Maybe the first jump isn’t the whole problem.”
Mara met Ada at the town hall and laid out the concern. Ada agreed to require a witnessed mechanical test at noon. She also arranged for the municipal events officer to be present. When Julian arrived, he was carrying a neat folder of certifications that Mara inspected carefully. The papers were legitimate but covered electrical distribution, flame-resistant fabric, and crowd barriers. None certified the old mechanism itself.
“You said your corporate engineer had signed the floor off,” Ada told him.
“He will after the operational rehearsal,” Julian replied.
“Who is he?”
Julian named a consultant, Daniel Sutter, who was traveling from another county. Ada immediately called the number printed in Brightline’s packet. Sutter answered on speakerphone and said he had agreed to examine the rigging and overhead loads, not the moving floor. He had never been sent its drawings.
Julian stood very still.
“It appears we had an internal communications issue,” he said.
Ada closed the folder. “Then there will be no public operation until we have a qualified assessment. That’s not negotiable.”
For a moment Mara thought the argument had ended. Instead Julian asked whether they could proceed with the static flower and independent lighting. Ada agreed, provided the moving apparatus was physically isolated and verified.
Julian thanked her, so politely that Mara was certain he intended another plan.

At lunchtime Ellis knocked on Mara’s garage door. His gray sweatshirt was streaked with grease. He looked as though he hadn’t slept.
“I need five minutes,” he said.
Mara kept the door open. “You have them.”
Ellis noticed the blue fob lying on her bench. He stared at the notch.
“Where did that come from?”
“Why does everyone ask that?”
“Because Julian told me there was only one original control key left. He said the others were destroyed.”
“Number four wasn’t.”
Ellis stepped nearer, then checked himself. “I didn’t build that floor. I repaired the actuators. Julian brought me diagrams, a partly assembled console, and twelve motor modules. When I asked why the wiring didn’t match the drawings, he said the original inventor had been eccentric.”
“What did you find?”
“A signal combiner. A modern one. It can receive timing cues wirelessly from the lighting desk and route them to the motors. Julian said the mechanical movements were preprogrammed and completely safe.”
“Did he mention input five?”
“No. I found that label inside the cabinet. I assumed it was an original connector.”
Mara showed him the twelve-petal sketch. Ellis looked it over and reached for a pencil. He drew a line from the missing twelfth motor to an adjacent panel.
“That’s how the new system is wired,” he said.
Mara’s stomach tightened. “Two channels driving one actuator?”
“Through a combiner, yes. Julian said it would make the petal look fuller.”
“What’s the timing overlap?”
Ellis hesitated. “About four-tenths of a second at peak extension.”
“Could the motor hold both loads?”
“It can hold the load. Whether the old pivot can is another question.”
“And the emergency key?”
“Julian says the emergency controls are handled from the lighting desk.”
Mara shook her head. “So if the lighting desk sends a bad cue, the same desk is supposed to rescue the floor.”
Ellis sat on a toolbox, suddenly diminished. “I told him I wanted a mechanical disconnect.”
“Did you fit one?”
“I ordered it. He said delivery would miss the show, so we could add it next week.”
“Next week?”
Ellis lowered his eyes. “I came because I don’t want my name attached to someone getting hurt.”
“Then help us disable the motion channels in front of Ada.”
“He’ll fire me.”
“Probably.”
Ellis rubbed his hands together. “I have two kids and a mortgage.”
Mara resisted the urge to make a speech about courage. Instead she gave him the number of a regional stage engineering cooperative where she sometimes subcontracted. The foreman had complained about being short two technicians just last month.
“Call them,” she said. “Don’t tell them a heroic story. Tell them precisely what work you can do.”
Ellis pocketed the number. “I’ll meet you at the gym after three.”
“Why after three?”
“Because Julian’s shipping the replacement controller to the park at two. He doesn’t want anyone seeing it installed.”
Mara walked him to the driveway. The red ladder, still there, cast a long shadow across the grass.

Evelyn spent the afternoon digging through her workshop for the original expansion connector. Mara found her surrounded by drawers and hardware bins, muttering measurements under her breath. The USB sat in the simulator, still showing its frozen warning.
