"Days of Our Lives" fans watched as Gwen Rizczech's schemes were unraveled, and it was proven that she had been drugging Abigail Deveraux to make her hallucinate months before meeting anyone else in Salem. Gwen eventually admitted that she was Jack Deveraux's daughter and Abby's half-sister — knowledge which made her jealous and caused her to seek revenge against Abby for having the childhood she never got to experience. Gwen went on to explain that she was the result of a brief fling between Jack and her mother, Tiffany Rizczech, although Jack claimed that he didn't remember anyone by that name. The two eventually had a DNA test done, which proved that Jack was Gwen's biological father.
Gwen told Jack that when she was a child, her mother had come to Salem to beg for financial help when they were in need. Instead, Jack was too busy with his wife, Jennifer Horton, and his daughter Abigail to be bothered. However, she did claim that Jack sent her mother money until the day she died. However, it turned out that Jennifer's mother, Laura Horton (Jaime Lyn Bauer), was actually the person who knew the truth, not Jack. Laura confessed to meeting with Tiffany and keeping Gwen's existence a secret from the family. Instead, she paid off Tiffany in hopes of preventing any problems in Jack and Jennifer's marriage.
Of course, Gwen felt like an outsider when all she really wanted was a father and a family. However, her scheming led to even more conflict between her and her newfound Salem family.
