Rebecca is relentless to see her daughter with the man she loves, even if it means the death of her grandson. Though the baby pulled through thanks to a liver transplant by Theresa's son Ethan, Rebecca threatened Pilar to keep quiet, and helped her daughter to misinterpret Theresa's selfless actions in Ethan's mind. When a wedge was established between the couple, Rebecca warned Gwen to be cautious of both Theresa and Esme Vanderheusen the best friend of Fancy Crane, and a notorious man user. Rebecca was accidentally stabbed by Esme's niece Viki, an unknowingly unstable serial killer. Though Rebecca survived she accidentally revealed to Ethan minor details about the Vasquez family when she learned Theresa and Pilar had gone to Mexico because of the threats of Juanita Vasquez. When Ethan left for Mexico, and Gwen followed Rebecca urged her daughter by phone to kill Pilar. When Gwen could not go through with it and revealed that Juanita had learned of their blackmailing schemes, Rebecca decided to leave Harmony, but was prevented by Sam Bennett, and Viki. Both Rebecca and Gwen were sent to jail for their various crimes; such as blackmail, fraud, bribery, and murder of not only Pilar's sister and nephews in Mexico, but also attempted murder on everyone in the basement of the church, when they were finally exposed in the series finale, mainly no thanks to Rebecca and her annoying babbling, one of her least attractive traits. During the series finale, Rebecca's babbling revealed that Gwen's marriage to Ethan was invalid due to Gwen already being married from a trip to Las Vegas.
