The practice objective was a crate of sand with a red cross painted on its lid. If they reached it before the bell, the imaginary patient inside would survive.
Kellan set the clock on a shelf at the training entrance. “Ten minutes.”
Sera looked from the clock to the three marked exits on the map. “Is there an imaginary injury?”
“Crushed leg. Needs the kit in the crate.”
“Then the crate is the patient or the kit?”
“The kit,” Kellan said.
Eli pointed at the red cross. “Why paint that on the lid?”
“So you’d know which crate to find.” Kellan wound the clock. “Would you both like to design a better exercise, or are we starting?”
Sera lifted her hands. “I’m ready.”
They had come back to the residual gate with borrowed markers, chalk, rope and a map supplied by the registry. Kellan had arranged the scenario while Eli and Sera waited outside. The approved area contained three connected routes, each marked with fixed lamps and return arrows. A registry officer had checked that the training site remained open, then left them to their exercise.
Before entry, they discussed the line Sera had written in her notebook: anyone could call a pause. Eli assumed that meant stopping when somebody saw danger. Kellan asked what happened if the person who called it and the person who wanted to continue disagreed.
“We vote,” Eli said.
“On what?” Kellan asked. “Whether the danger exists, or whether we accept it?”
“Both, I suppose.”
“Those aren’t the same.” Kellan put three chalk marks on the table. “Suppose I see a cracked support. Sera senses a current beyond it. You see no strain in the support. We can agree the crack exists and still disagree about crossing.”
“Then we say what each of us knows,” Sera said. “And what waiting costs.”
“And if we can’t agree?” Eli asked.
“We don’t make a person walk into a route they’ve called unsafe,” Kellan said. “We find another route or end the job.”
Eli thought of Corvin ordering the expedition forward while the corridor cracked. Tessa had won authority to call an evacuation, but the paper had not made the leader listen until the danger was in front of him. A rule only mattered if they were willing to accept the cost when it slowed them down.
“All right,” he said.
Sera wrote it beneath yesterday’s note. “A pause. Evidence. Cost of waiting. Then a route we can all accept, or we stop.”
The clock began ticking. Kellan picked up a training pack weighted to match a medical kit. Eli carried the rope; Sera took the marker reader, though her talent did the sensing. The reader could confirm whether a marker was active once she had found it, but it could not tell her which direction to go.
They entered the gate. The first passage was familiar from yesterday’s test. At the bend, Kellan pointed to a chalk arrow he had added to the wall.
“Short route to the objective. Four minutes at a walk, if we find no problem.”
“The other routes?” Eli asked.
“Six minutes through the upper loop. Eight around the storage passage.”
Sera closed her eyes. “There’s a marker somewhere near the short route. One near the upper loop too. I can’t tell where either source is exactly.”
“Are they moving?”
“Not that I can tell.”
They chose the short route. Kellan walked first, testing the floor with a pole. Eli followed with his attention on the walls. When he drew on Weak-Point Sight, thin lines appeared in a support ahead: pale where strain gathered along a joint, brighter around an old crack at its base. The sight gave him the locations, not a verdict on whether the structure would hold.
He showed Kellan. Kellan crouched and ran a finger along the crack without putting weight on the support.
“Old repair,” he said. “The patch is sound where it meets the beam. The floor beside it is another question.”
Eli looked down. A patch of loose grit had collected at the floor-wall joint. He had seen it without considering what it might mean.
“Could be from the wall,” Kellan said. “Could be from the floor shifting. I want to see where it starts.”
Sera had moved to the opening ahead. She held up a hand. “Pause.”
The clock ticked in Eli’s memory, though it was too far away to hear. He stopped beside the support. “What changed?”
“The current near this route rose, then moved toward the junction. I can’t tell whether the source moved or the path opened.”
Kellan tested the floor beside the loose grit. A small section sank under the pole and settled again. He pressed harder. A line of dust lifted where the wall met the floor.
“Loaded crossing might break that edge,” he said. “I can’t say it would collapse, but I don’t like carrying the pack over it.”
Eli looked through the opening. The corridor beyond was clear as far as the next lamp. His sight showed no bright fracture in the main beam. “The support itself looks stable.”
“The floor isn’t the support,” Kellan said.
“We could cross one at a time and keep to the wall.”
“Which wall?” Sera asked. “The current changed behind the one on the left.”
“It may only be the marker.”
“It may. That’s why I called a pause, not a retreat.”
Eli checked the time on his watch. Three minutes had gone. They had seven before the imaginary patient died. The short route might still get them there if they crossed carefully. The upper loop would take longer, perhaps too long.
“What happens if the floor drops?” he asked Kellan.
“With this load? I don’t know. It could settle an inch. It could open enough to trap a leg. The rope would help us get someone out, but we’d lose more time than taking the loop.”
“And if the signal is moving?” Eli asked Sera.
“In a live gate, I’d want eyes on the other side before calling it clear. Here it’s a marker, but I don’t know what Kellan set up.”
Kellan held up his hands. “I’m not confirming the setup until we’re finished.”
Eli took a breath. “The cost of waiting is the deadline. The cost of crossing could be an injured carrier and no kit. I vote for the upper loop.”
Sera looked surprised. “You wanted the short route.”
“I still think it might work. That doesn’t make it the best risk.”
They turned back. At the junction, a blue arrow pointed up a ramp. Kellan checked the handrail before climbing. The ramp was narrow enough that the pack scraped the wall, so Eli took it and turned sideways while Kellan guided the straps clear. Sera led them to the next intersection, stopping every few steps to distinguish the two currents.
“One is below us now,” she said. “The other is ahead. I think.”
“Which one did we feel near the short route?” Eli asked.
“I can’t prove it. The pressure is stronger here, but that may be the wall.”
They found the objective at the far end of the loop. The red cross was visible beneath a shelf. Eli pulled the crate free while Kellan checked the route back. Sera looked at her watch.
“Eleven minutes.”
“Patient didn’t make it,” Kellan said.
The crate was heavier than Eli expected. He opened it and found bags of sand, each labeled with an item a medical kit might contain: dressings, fluid, a splint. Beneath them lay a card that read PATIENT DIES AT TEN MINUTES.
Sera set her reader on the floor. “My pause cost us the exercise.”
“It cost time,” Eli said. “We don’t know whether the short route would have held.”
“We know the patient died.”
Kellan took the card and turned it over. On the back he had written the setup: one marker fixed behind the short-route wall; the second on a long cord running back through a pulley at the entrance to a handle hidden in his pack. He had pulled it while they approached the support, shifting the second marker along a groove near the junction. The signal had changed because the second source moved, but it had not approached from behind.
“The floor edge was real,” he said. “The registry opened this section for training, but I failed to check whether anyone had tested that edge with a load. I treated an open route as a tested route.”
Eli looked at him. “You knew the short route had a weak edge?”
“No. I saw the grit when you did. I should have asked about load limits before we started. My setup put a deadline on you before I had checked the floor.”
Sera’s jaw tightened. “You made it sound like all three routes were available.”
“I said they were marked on the map. You’re right, I should have checked what the inspection covered before we started. In a real job, assuming a route can take a loaded crossing could get someone hurt.”
Kellan rubbed his thumb against the edge of the crate. He had been the person insisting that an open route did not prove a safe one, and he had sent his teammates toward the uncertain floor while a clock urged them on. The embarrassment came hot and immediate.
“I wanted you to test the pause rule under pressure,” he said. “I was so busy setting the pressure that I forgot my own inspection.”
Sera picked up the card. “Then that part of the test is yours.”
“I know.”
She held it out to him. “Write it down. I’ll write down that I nearly let the deadline push me across.”
He wrote the correction on the back of the card. Eli was grateful Kellan had admitted it without turning the whole test into a trick they were supposed to admire.
“What would we do differently?” Kellan asked.
“Put a kit closer to the junction before the clock starts,” Sera said. “Or have one person scout the upper route while the others check the short one.”
“Separating has a cost,” Eli said.
“Then give the scout a line and a return time. We spent three minutes walking together before we even knew which route was blocked.”
Kellan drew the route on the crate lid. “If the patient is already inside, an advance kit is only possible if somebody planned for it. We can still test a split. No one crosses the damaged edge.”
They reset the clock. Sera took the upper loop while Eli and Kellan checked the short-route opening. A rope tied to her belt ran through Eli’s hand. At the first junction, she called out that the signal from the marker was stronger, but she had a clear path. Kellan confirmed the loaded crossing remained untested, and they followed her route without repeating the inspection.
They reached the crate in nine minutes. When Eli opened it, Kellan took out the sandbags while Sera checked her notes.
“That worked because we already knew about the floor,” she said.
“Yes,” Kellan replied. “It’s a practice of the alternative, not proof we’d have made the same choice cold.”
Eli found a folded paper beneath the last sandbag. Kellan had forgotten it in the crate. It listed the people he intended to pay for the next supply delivery, with Theo’s appointment date written in the corner. The number beside the date was larger than Eli’s last contribution to the clinic.
He held the paper out without reading further. “This is yours.”
Kellan took it and folded it into his pocket. “The supply-run payment covered part of it. The next appointment will cost more.”
“Do you need an advance?”
“No. You already paid me. I need to plan for the next bill.”
“All right.”
Sera adjusted the marker reader’s strap. “I need training time, not an advance either. Does tomorrow’s agreement include equipment?”
“We can reserve the markers for two sessions next week,” Eli said. “If they’re available. I’ll confirm before promising.”
“And the route decisions?”
“Same pause rule.”
“Even if the deadline is real?”
He considered the card on the crate. “Especially then. We might decide to take a risk, but we’ll name it before somebody else pays for it.”
They carried the crate back together, switching hands at the ramp. At the training desk, Sera asked the officer whether the uncertain floor condition would appear on the next group’s briefing. Kellan added his own report that the edge had moved under light pressure. The officer wrote both down and closed the route pending inspection.
Outside, Sera marked the first test as a failure in her notebook. Beside it she wrote that the team had chosen the longer route and reached the objective after the deadline. She marked the second test separately, with the advantage of prior knowledge noted beside the time.
“You don’t have to make yourself look worse,” Eli said.
“I want to know what happened when I read it next week.”
She tore out a clean sheet and drew the measured-distance exercise they had discussed. Kellan offered to build a simple track for the moving marker from scrap timber. Sera accepted, provided the track’s position was hidden during some trials.
At the station they parted. Eli headed toward the clinic to help Leah review the clinic inventory. Tessa’s assessment was the next day, and he wanted to ask how the home visit had been arranged. Sera went to reserve training time. Kellan left for his construction shift, carrying the rope and the marked card.
The exercise had ended without injury. The imaginary patient had not survived the first attempt, and the team could not erase that result by succeeding once they knew the route. They had learned enough to try another arrangement. The next time they argued over a warning, they would have a rule and a failure to remember.
