How is Wab and Frenchie's stories similar or different?

At eighteen, Wab is the oldest female member of Miig’s group. She has a vicious scar that splits her face nearly in two. Wab used to be a runner who worked delivering messages and packages in Toronto. She suffered significant trauma, including neglect by her mother and physical and sexual abuse by the gang that put her out of work. She is fragile and stingy with her words. She develops a romantic relationship with Chi-Boy and is expecting a baby at the end of the novel. I'm not sure how similar they are. They are both indigenous, around the same age, and suffered trauma in their past.
