Foil

Foil is a literary device that involves the use of a character who contrasts with another character in order to highlight certain qualities or traits of the other character. The foil character is often portrayed as a contrast to the protagonist or another important character in the story. This contrast can be used to emphasize the differences between the two characters, highlight certain themes or motifs, or provide a better understanding of the protagonist's qualities. Foil characters can be similar in many ways but differ in key areas, or they can be completely opposite in terms of personality, behavior, or beliefs.

A foil is a character whose similarities and differences make another character's traits easier to see. Identify the specific points of contrast and explain what those contrasts reveal rather than merely listing two different personalities.

Both candidates face the same accusation; Lina admits her error, while Corin blames an assistant.
Their contrasting responses make Lina's accountability and Corin's evasiveness more visible.
