Mateo never demanded payment. When Isabel offered, he shook his head. “Fixes aren’t for sale,” he said. “They’re for keeping.” Instead, he accepted coffee, a sandwich, and the quiet permission to be present during screenings.

He began to keep a small notebook in his pocket where he scribbled things—dates, little diagrams, and sometimes lines from the films.
