Felix put the pump on the table, then the wheel, then the valve model.
He stepped back to admire the arrangement.
Lyra tried to leave the workshop and found the table in her way.
He moved it.
“A useful opening lesson,” she said.
“Audience management.”
She waited until the exit was clear before setting the petition beside his labels.
He had made quite a lot of labels. The largest named the principles connecting intake, storage, release and return. Another described stable repeated operation. A third had taken so long to letter that he no longer wanted anyone to ask what it meant.
One label had to dry flat, so he balanced it on two empty cups. Lyra moved the cups to make room for the petition and the paper sagged into the gap.
Felix caught it before the ink touched the bench.
“That took a while.”
“I can see. What’s it teaching?”
He held it up, considering the lettering.
“Confidence.”
“Yours?”
He put it somewhere safer.
The pump’s clear test vessel had lost its stopper. He found it under the wheel, where he’d placed it to keep the table symmetrical. The valve model blocked the pump’s return line from the audience side. Moving the valve hid the small wheel.
For several minutes he rearranged things without removing any of them. Each solution created a fresh obstacle. Barnaby watched from the beam above with the patient interest of someone observing a familiar dispute between available space and human preference.
At last Felix moved the wheel behind the pump.
“Now nobody can see that,” Lyra said.
“They’ll appreciate it later.”
She didn’t answer. That was unusually effective of her.
He looked at the line of devices and imagined explaining each while the audience waited for the next. The polished table began to resemble a market stall where every seller had arrived late and claimed the same good spot.
Tamsin came in carrying the cold practice board.
“What will the learner do afterward?”
“Recognize a safe circuit, understand the relation between—”
“One action.”
Barnaby counted the devices.
“You have brought several answers. None is singular.”
Felix looked at the pump. In his imagination, Corven watched from the back while Jory Pike discovered that useful work could be impressive. The demonstration ended with several people admitting they’d been wrong, preferably in writing.
“The people paying for instruction may want to learn even if Jory doesn’t come,” Lyra said.
“I hadn’t required his attendance.”
“You put him on the possible audience list.”
He turned the list over.
Jian arrived for the practice interval he’d agreed to provide. He read the apparatus notes, looked at Felix’s arm and removed the suggested power display before it became an argument.
“No anchored release.”
“It’s crossed out.”
“Now it is.”
They agreed to rehearse a cold lesson first. No pressure, no dangerous charge, no need for Felix to prove anything through the injured meridians. A later tiny live example would use the apparatus supply within tested limits, with Jian checking it.
It sounded smaller than the event Felix had pictured.
Pell asked if he could try the model. Tamsin checked the disconnected feed and gave permission for that task.
Felix set the board where he could see the indicator, then handed the boy the intake control.
“Open it until that settles.”
Pell turned the control. A little mechanical marker moved, wavered and came to rest near the line.
“Is that settled?”
“Nearly. Ordinary fluctuation’s fine.”
“How much?”
Felix explained the return behavior. Then the difference between rising pressure and harmless vibration. Then the way a delayed response could resemble a blockage without actually being one.
Pell watched him patiently.
“What do I do?”
“Watch the marker.”
“For what?”
Felix pointed at the paper arrow.
From his own height, the stop line was obvious. From Pell’s, the arrow hid it.
The boy tilted his head, then turned the board to see around the label. The loose return tube slipped behind the backing.
“Don’t turn it,” Felix said.
Pell let go at once.
“I couldn’t see.”
“It’s arranged for the demonstration.”
Tamsin folded her arms.
Felix knew that expression. He had seen it at the timber yard, the drying rack and several increasingly educational pieces of laundry equipment.
“An adult with gloves might do the same thing,” she said.
He looked at the empty feed connection. The model was safe. That didn’t make the lesson useful.
Pell stood beside the control, waiting to be told whether he’d failed.
Felix took his hand off the board.
“Tell me when you’d stop it.”
“When the marker goes strange.”
“What’s strange?”
Pell looked at the hidden line.
“I’d call you.”
It was a sensible answer to the explanation he’d been given. It was also not an answer that let Felix ever leave the room.
Lyra tried next. She stopped at the proper position, then admitted she’d assumed the same limit she used in a basic ward.
“You didn’t explain that,” she said. “I supplied it.”
Barnaby read the written instructions.
“Watch for change. Do not respond to ordinary fluctuation. Define ordinary.”
Jian operated the model correctly without needing either statement. He’d learned the missing distinction years ago.
Felix looked from one person to the next. They hadn’t found the same problem. That made it harder to dismiss them as a group simply determined not to enjoy his splendid table.
“Tea,” he said.
“We haven’t finished,” Pell said.
“I need to stop before I explain worse.”
The kettle worked without asking him to supervise it. He filled his cup, sat where his arm was comfortable and watched the steam.
On Earth, he’d once spent half a day proving that an error couldn’t happen because the intended sequence prevented it. The person reporting it had not performed the intended sequence. That was precisely the problem.
He could remember how offended he’d been before he’d remembered to reproduce it.
Pell came for a drink while he was sitting there. The boy took a cup without trying to join the silence, filled it and leaned against the kitchen table.
“Was it a bad question?” he asked eventually.
Felix set his own cup down.
“No.”
“You looked as though it was.”
“I was expecting a different question.”
“What one?”
He thought about it.
“Probably how I made it work.”
Pell glanced toward the workshop. “I thought you’d already made that part work.”
There it was. The device wasn’t the unfinished bit.
Tamsin came through to collect a measuring strip and heard the last sentence. She checked Pell’s face, then left the strip beside the door while she gave him a fresh piece of bread. She didn’t answer for either of them.
Felix picked up the long instruction sheet. He could follow every sentence because he knew what he’d meant before writing it. The page kept borrowing that knowledge without giving any back to a new reader.
He folded it rather than throw it away. There were useful details in it. They belonged somewhere after the first clear action, not where a learner needed the first clear action to be.
Pell finished his water and returned to the kitchen table. He had game pieces to arrange, a mother working nearby and no apparent desire to become an example of educational theory.
Felix rinsed his cup, set it upside down to dry and went to ask for another try.
In the workshop, Pell began sorting a little stack of game pieces. The lesson had not become the most important event in his life just because Felix had made labels.
Felix went back before the boy had finished his first arrangement.
“I’m sorry. You asked a useful question. I answered as though you were interrupting.”
Pell looked up.
“Can I still finish these?”
“Yes. When you’re done, would you try again?”
The boy considered, then nodded.
Felix removed the large arrow. He set the normal resting position first, with the marker visible from both sides and a plain line showing the boundary. The return tube received a simple retaining loop so turning the board didn’t hide it.
He moved the stop where a cloth-covered hand could reach it without crossing the intake.
Then he took almost everything else off the table.
The wheel went back to its shelf. The pump remained nearby as an example, not a second lesson. The grandest label came down last.
Barnaby examined the blank space.
“May I label that absence of boasting?”
“No. It would disturb the composition.”
The owl let the empty space perform its function.
Felix waited for Pell to finish arranging his game pieces. Then he invited him over, lowering himself enough to see the model from the boy’s position.
“This lets it in,” he said, pointing to the intake. “This is where it leaves after use. This stops it. Here is normal.”
He moved the cold model through its ordinary range.
The marker stayed inside the line.
“And this is the change we’re watching.”
He shifted the model’s simple resistance. The marker crossed the boundary slowly enough to see.
He pressed the stop.
“Now you.”
Pell began the sequence. He didn’t need a sentence about every way a different apparatus could behave. This model had a visible normal state, one defined deviation and an action he could take.
When the marker crossed, he stopped it.
Felix kept his mouth closed until the boy looked up.
“Good.”
Pell reset the cold model and did it again.
Lyra took a turn, deliberately rotating the board as she’d seen Pell do. The retaining loop kept the return visible. She could still reach the stop and read the line.
Jian checked the planned tiny live version, identifying the apparatus supply and the cutoff. No portion required Felix’s right arm to become an exciting example of what the lesson warned against.
Tamsin checked the stand, pushed against its feet and moved a loose cloth clear of the outlet position.
“Now it’s a bench someone can use,” she said.
Felix looked at the stripped table. It was much less impressive to someone watching from the doorway. He could imagine Corven calling it elementary.
It was elementary. That was what they’d offered to teach.
He picked up the original instruction sheet and crossed out the long paragraph he’d tried to make Pell remember.
He checked the new line from his chair, from the door and from the low stool Pell had used. It remained visible. None of those positions made the table look more impressive. They did make it easier to see what actually mattered.
“Invite the observers?” he asked.
Lyra shook her head.
“We still need the venue, witnesses and the petition lodged. And there’s a new application from Rusk.”
The name spoiled a little of the morning.
Felix looked at the working model, then at her satchel.
“What kind?”
“Specified records. More precise than the recovery warrant. We need to read the actual order.”
He wanted the rehearsal to become a public success while it still felt good. She wanted to keep the evidence available for the hearing. Neither desire made the other disappear.
“All right,” he said. “The demonstration can wait.”
Pell took his game pieces back to the kitchen. Tamsin left the cold model disconnected and ready for further practice. Jian returned to his own work after confirming the agreed next interval.
Barnaby met the recorded delivery at the landing.
The new order named original shipment pages by dates and identifiers. Lyra spread it beside the narrowed teaching notes and read without speaking for a while.
“Witnesses,” she said finally. “And a neutral room. Examination doesn’t have to mean surrender.”
Felix stood beside the clear exit, where he could see the whole table without blocking anyone.
“Tell me where you want me.”
She looked up, then pointed to the document board.
“Carrying that. And remembering what I actually agree to.”
He picked it up with his left hand. On the table, the plain stop line remained visible beside the much more difficult boundaries of the order.
