Blackmailing Julian wasn't her only plan though. Rebecca decided to turn the tables on Theresa and make Theresa pay for everything she had done to Gwen over the years by taking her son away. She had an even deeper motive; she planned to arrange for Ethan and Gwen to adopt Theresa's son, to replace the child Sarah Winthrop that they had lost. Although Rebecca came to care deeply about her stepson, she firmly believed he was better off without Theresa in his life, and knew that Gwen and Ethan could provide him with both love and stability. After child protective services deemed Theresa an unfit mother and the courts terminated her parental rights, Rebecca used her influence to get Julian to sign away his rights to his son and to convince Judge Reilly to approve Ethan and Gwen's adoption of the boy. When she learned that the baby Theresa was carrying for Ethan and Gwen could be the result of Theresa's rape of Ethan, Rebecca swore to finally get her vengeance on the girl who had caused her daughter so much pain. At the same time, Rebecca, desperate to keep her husband, decided to poison Eve Russell.
