Dr. Elara Venn had spent twenty years mapping the human psyche. Her life’s work was a taxonomy of traits, a periodic table of the soul. She could look at a person’s answers to her 500-item questionnaire and predict, with 87% accuracy, how they would vote, whom they would marry, and when they would crack under pressure. To Elara, a person was a constellation of five bright stars: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The OCEAN. The only ocean that mattered.

“This is an error in the software,” she said, tapping her tablet.

“Is there a difference?” Silas turned to her, and for the first time, his eyes held something real: exhaustion. “Your science measures the mask a person wears most often and calls it their face. But what if someone has no favorite mask? What if their nature is to have no nature?”

Her latest subject was a problem. Patient 734, who called himself “Silas,” was a ghost in the system. He had no medical records, no digital footprint, no family. He had walked into her clinic on a rainy Tuesday, asking for a “complete personality assessment.” He was polite, well-dressed, and utterly unreadable.

She never saw Silas again. But sometimes, late at night, she would catch herself speaking differently to different people. She would notice a laugh that wasn’t hers, a frown she had borrowed from a patient, a gesture stolen from a stranger on the subway.
