Ethan didn’t even look at them as they shook. He turned to the board, and for the first time, the room really watched him—his posture, his breathing, that focused gaze. This wasn’t a child playing.
This was someone working.
He began to write.
At first, the men smiled, expecting nonsense. But the symbols weren’t random. There was structure. Method. Ethan moved quickly, without hesitation, as if the solution already existed fully formed in his mind and his hand was simply translating it.
The laughter faded—one voice at a time—like lights shutting off in a building at night.
The only sound left was the marker against the board.
Shh. Shh. Shh.
Even Richard stopped moving.
Five minutes passed. Then ten.
The board filled like a map—branches of calculations, corrections, arrows, clarity carved out of complexity.
Laura felt a lump rise in her throat. She knew enough to understand: this wasn’t an act.
Richard slowly stood. His smile was gone.
“Is he… actually calculating?” someone whispered.
Ethan kept going. When he finished, he stepped back, examined the board like an artist reviewing his work, then circled a number in the lower corner.
“Done,” he said simply.
“The issue is the load distribution on the south pillar. You’re assuming uniformity, but the wind enters at an angle, creating asymmetric pressure.”
No one spoke.
Richard approached the board as if hypnotized. He wasn’t an engineer, but he had worked with enough of them to recognize a serious mind. His fingers traced the lines, the numbers, the decisions.
His breathing changed.
“How… how did you do this?” he asked. The mockery was gone. What remained was fear—fear of having been wrong.
Ethan shrugged.
“It’s not that hard if you understand the basic principles and know how to apply differential and integral calculus.”
Basic.
The word landed like a slap.
Victor leaned forward.
“This is graduate-level work.”
“I know,” Ethan replied, without arrogance. “My mom taught me.”
“Your mom?” Richard blinked. “She’s an engineer?”
Ethan hesitated for the first time. His voice cracked.
“She was. One of the best.”
Laura felt something tighten in her chest.
“Where is she now?” Richard asked quietly.
Ethan swallowed.
“She works nights… as a janitor. In an office building.”
The room froze.
The image was absurd—a brilliant engineer hidden behind a cleaning uniform. Victor voiced what everyone was thinking.
“Why?”
