Notkin spills (pp. 793–794)
retired from childhood’s twirling and carving out an adult career on one and potentially two sides of the film-camera
Context
Joelle's professional self-description at the Thanksgiving table, via Notkin: "one and potentially two sides of the film-camera" — performer and, potentially, filmmaker. The clause quietly confirms the directing ambition her radio persona and her apprenticeship with JOI (068, 150) keep implying: the camera has two sides and she intended both.
