"Probably not. We'd need to confirm with independent readings, but that's what the evidence suggests."
Marcus studied the tiny component in Evan's hand. His expression changed from skepticism to professional alarm, and he asked Nadia for the original build log. Charlotte noticed that he no longer sounded annoyed. The fault had become too serious for pride.
A replacement component from the approved inventory was fitted after the system was again made safe for service. Nadia completed the necessary checks, the technicians reassembled the housing, and Marcus authorized a controlled test on the stationary equipment. The motor responded smoothly. The temperature traces settled into the expected pattern, and the protective fault failed to reappear through the test cycle.
For several seconds nobody celebrated. The room was full of experts who understood that a successful bench test was not the same as a full validation run. But it meant the vehicle could proceed to the next stage without replacing a battery pack that might never have been defective. It also meant a mechanic who had arrived without an appointment had found something six engineers had missed.
Charlotte exhaled. "Can the car make the investor demonstration?"
"After your team signs off on the remaining tests, yes," Evan said. "I wouldn't put investors in a performance car until you've checked every connection from the same parts batch."
Marcus nodded reluctantly. "He's right. We should quarantine those components."
Charlotte turned to Evan. "Who taught you to think like that?"
He laid the tool carefully back in its tray. "My father."
The answer was quiet, almost offhand, but it changed the room for Charlotte. She remembered Daniel kneeling in front of her twenty years earlier to explain the difference between a defective part and a defective assumption. He had been patient even when she had asked questions her father considered foolish. She wondered how many evenings he had spent teaching his son with the same patience and what else had been taken from the boy when Daniel died.
"You're hired," she said.
Evan blinked. "I haven't had an interview."
"I just watched one."
"We haven't discussed pay."
"You will receive an offer through human resources with the published salary range and full benefits. I won't ask you to work until you've seen it and accepted."
That caught Evan off guard more than the promise of employment. He had expected an argument about qualifications or a vague offer to start as a temporary laborer. Instead, Charlotte asked Nadia to introduce him to the supervisor responsible for onboarding and to explain the certification procedures. The practical world suddenly began moving too quickly for him to follow.
"There is one thing," he said.
Charlotte paused. "Tell me."
"Thursdays I have to leave by four thirty. My daughter has therapy, and nobody else can take her. I can come in early, or make up the time another day."
"Four thirty on Thursdays," Charlotte repeated. "We'll work around it."
He looked at her as though he expected the condition to be withdrawn. She extended her hand, and he shook it, conscious of how rough his fingers felt against her cool palm. Behind them, Marcus watched Charlotte's attention linger on the stranger's face. The company had hired a mechanic, but something else had begun, and Marcus seemed to recognize it before anyone spoke.
