Answer 3

In "Twilight," Bella undergoes a transformation from a shy, reserved girl to a more confident and determined individual. She becomes more willing to stand up for herself and those she cares about, and she gains a deeper sense of her own identity and strength. Bella also grows stronger emotionally as she navigates her feelings for Edward and the challenges they face together.
