She started seeing a therapist to discuss the rocky relationship with her family, because she could not cope with her mothers actions as well as dealing with her emotions regarding Underwood and his death. Farrah eventually proved to Derek's family through a paternity test that Derek was in fact Sophia's father and then was faced with a lawsuit filed by Derek's mother for grandparents' visitation rights, despite no previous contact with Sophia.

Bookout said the reason she participated in the show was because she wanted to get a good message across and stated: "I really just wanted to show girls how hard it was to be a teen parent. I wanted girls who might get pregnant to see there are options out there to move forward with your life and still have goals."
