He smiled and pulled up a fresh CAD file. Somewhere in the plant, another tool was whispering. And he was the only one who could hear it.
Line 3 ran all weekend without a single fault.
Leo was already pulling on his safety glasses. He didn’t walk to the line. He drifted. In his mind, he was already inside the failure.
