Who knows what—and when?
Select a hinge episode to compare John, Lucy, the police team and audience knowledge without flattening the entire series into one relationship chart.

The important variable is who recognises whom
Five object clusters show identity, family and institutional knowledge before the interactive tracker supplies the changing states.
Hinge states summarise the broadcast and preview boundaries currently held by the archive. They are not a substitute for a scene-by-scene transcript.
A state scale without invented percentages
This scale will govern future character charts. It describes evidence in the story rather than claiming access to a character’s private certainty.
Charts will cite an episode hinge and a concise paraphrase of the supporting scene. Audience knowledge, character knowledge and editorial inference will remain separate fields.
