Clementine is introduced as a free-spirited, impulsive, and emotionally expressive woman who often changes her hair color to match her mood. While she initially appears to fit the "Manic Pixie Dream Girl" trope, the film reveals her deep insecurities and fears of being a concept in men's minds rather than a person with her own needs.
