Analysing the Characters in Step by Wicked Step
Pixie is a smart girl. She is the first to realize what the five of them have in common. She is also brilliant at reading. She does not like it when Hetty moves into her bedroom, so she thinks of creative ways to get rid of Hetty.
Besides, Pixie is also a brave girl. She is not scared to express her thoughts. She tells Lucy exactly what she thinks of her and her 'ratty, squabbling' daughters. Being honest is good for her because later, she does not have to pretend anymore. Everyone knows how she feels, and she knows how others feel.
