She was kidnapped by her father and grandmother when she was a baby from her mother. She was secretly raised in England by her grandmother under her grandmother's maiden name. During her whole life Harris and Judith poisoned Emma to hate Ann and, like her mother before her, she was led to use anxiety pills to overcome her father's and grandmother's strict upbringing.
At the trial of Ann's shooting of Harris, Emma realizes that her father and grandmother have been lying to her her entire life when she hears the true story of her disappearance and her mother's suffering at the hands of Harris and Judith. Emma leaves her father's house and goes to Southfork to stay with the Ewings. Now Emma and Ann start to bond and get to know each other.

Emma helps the Ewings in taking down her father.
