Samira's empty desk, the one in the third row, began to frost over. Ice crystals spread from its centre, spiderwebbing across the grey laminate.

Dr. Varma looked at him for a long time. Then she opened a drawer, took out a faded yearbook from 1987, and turned to a page marked with a ribbon. A girl smiled up at him. Same nose ring, different decade. The caption read: Samira Jahangir – Math Club President. "She saw the shape beneath the shape."

The tapping stopped. A voice, dry as insect wings, whispered from the direction of Samira's desk: "The formula is wrong. Euler forgot the hole in reality. Count the vertices again, Mr. Elias." classroom76x

He didn't ask who. He handed out the worksheets with trembling hands. For the remaining thirty minutes, the class worked in perfect silence. When the bell rang, the students filed out without a word. Leo paused at the door. "Mr. Halbeck tried to rearrange the desks," he said quietly. "He's in the hospital. Something about his reflection moving wrong in a bathroom mirror."

The students were all looking at him now. Eleven pairs of eyes, utterly patient. Samira's empty desk, the one in the third

The door to Classroom 76X did not have a window. This was the first thing Elias noticed on his first day as a substitute at Alder Grove High. Every other room on the fourth floor—74X, 75X, 77X—had a narrow, wire-meshed glass panel. But 76X was a slab of painted steel, the colour of old bone, with a handle that felt greaseless and cold.

He stared at it. The students did not. They kept their eyes on their notebooks, on the board, anywhere but the clock. Then the light changed. The fluorescent hum dropped an octave, and the F-sharp became a deep, throbbing C. The air thickened, tasted of ozone and old paper. The chalkboard, clean a moment ago, began to show faint impressions—equations that weren't his, diagrams that twisted into impossible knots.
