Final answer:
Characters in 'After dark' demonstrate significant changes from beginning to end, mirroring the metaphorical transition from night to dawn, which symbolizes their development and the resolution of their narrative journey.
Step-by-step explanation:
In the context of the book 'After dark', characters often undergo significant changes from the beginning to the end. It is a common narrative device for a character to start off in one way and end quite differently after experiencing various plot events. The change can be evident through the characters' actions, decisions, and personal growth.
One illustrative way to consider character changes over the course of a narrative is to reflect on how dawn and night offer metaphorical representation in literature. Like the fluctuating light described on the paper in the except, which seems to change personalities, characters might seem one way in the deceptive 'light' of their initial situations and quite another by the story's end.
Also, the end of a book or story is often where the falling action and resolution provide a clear view of how the characters have developed. Their changes can manifest as a response to the conflicts they've endured—a transformative 'journey' that has potentially made them 'wiser' or altered in some fundamental way.
These changes reflect the very core of a story's progression, effectively shaping the readers' overall experience and perception of the tale. In the end, this character development or lack thereof can significantly influence what the audience takes away from the narrative.
