When her sister Amanda died in season 1, Emmalin struggled to deal with her grief but hid it away from her parents.

She had a rebellious streak and a strained relationship with her father since then. After getting informal counseling from family friend Dr. Roland Burton she eventually works through her grief and anger. Father and daughter eventually repair their relationship in Season 3.
