What is a good description of the theme of a story? theme introduces characters. theme is important to the setting. theme is a big idea. theme is the subject of the story.

without doubt big idea. people could think others, and others would be wrong, backup proof, ¨The theme in a story is its underlying message, or 'big idea.' In other words, what critical belief about life is the author trying to convey in the writing of a novel, play, short story or poem? This belief, or idea, transcends cultural barriers. It is usually universal in nature.¨ Thank you for your time!

in that passage i would say the sentence which best describes the overall impact of the setting is when they mention the absence of people because it suggests that taking a walk at night is unusual.

its repetition emphasizing that the chain is his own. sorry if i am wrong.
