How does the quote,"You should have brought the flashlight, Jem" create mood in To Kill a Mockingbird?The quote is in Chapter 28, at the beginning...

I don't think this particular quote lends a tremendous
amount of mood or atmosphere just by itself. However, it does foreshadow things to come
after the children return from the Halloween pageant at the school.
Harper Lee has already begun creating the foreboding mood of darkness and fear in the
preceding paragraphs, describing the children walking past the Radley Place in the
receding twilight by themselves. (Remember, Atticus would normally walk with the
children after dark, but he was too tired after being in Montgomery all week.) There is
the mention of shadows, a strong wind and the possibility of rain. The children have
been talking of "Haints, hot steams and incantations" as they feel their way forward,
careful not to bump into a tree. Scout trips on a tree root just before making the
comment about needing a flashlight, and then they are both surprised when Cecil Jacobs
jumps out and scares them. They seem relieved for Cecil to join them on the remainder of
their walk to the school, but afterwards, by themselves in the dark, the mood turns from
scary to murderous.
