What is an 'epiphany' in a character's development?

An epiphany in a character's development is best defined as a moment of sudden realization or insight. This pivotal moment often leads to a significant change in the character's understanding or perspective, enabling them to see things in a new light or reevaluate their beliefs and actions. This newfound awareness can drive the character's decisions moving forward and is crucial in showcasing their growth throughout the narrative. It's a transformative experience that can impact not just the character, but the overall direction of the story itself. In contrast, the other options focus on different elements of storytelling: introducing minor characters, developing thematic materials, and detailing plot events, none of which capture the essence of an epiphany.
