Question

. Why does the narrator use irony in the plot?

Answer 1

Irony is used to suggest the difference between appearance and reality, between expectation and fulfillment, the complexity of experience, to furnish indirectly an evaluation of the author's material, and at the same time to achieve compression.

Most forms of irony display a disparity between what the characters think can, should, or will happen and what actually transpires. This can spark strong feelings in the reader and serve as a way to teach practical or moral lessons.
