Marissa is the other main character whose perspective is conveyed in third person, allowing for distance from the reader. She navigates themes of loyalty and appearances, with her actions driving much of the plot's conflict.

As the book's antagonist, Matthew is a complex character with little revealed about his inner thoughts until the conclusion. His dual nature and deceptive appearances play a central role in the story's twists.

Known as "the other man" in Marissa's affair, Skip is a close friend of the Bishops. His character functions as a pivotal plot device and serves as a red herring within the narrative.
