The end of the story . . . Is never really the end of the story.
In part because the story has not yet been fully told. Other scenes have been left out for sake of time and will be recounted. Deep memories will surface. Forgotten side-characters will be brought back into view. New connections will be made between old details. New meaning will be found in old tales. So your story from tthe past isn’t really over . . . it’s actually part of your story right now.
