Dina Mergeron - Jessica Blair Grainger

Jessica Blair Grainger (formerly Abbott) was the mother of Christine Blair and wife of the late John Abbott, Sr. She was portrayed by Rebecca Street from January 1988 to her death onscreen in November 1989.

History
Jessica, the estranged mother of Christine Blair and the aunt of Joe Blair, who left town a year before Jessica arrived, arrived in Genoa City suffering from AIDS and hoping to reunite with her daughter before the disease eventually claimed her life. Eventually Jessica and Cricket made amends. However, Jessica originally tried to keep her illness a secret from everybody in town, including John Abbott, with whom she fell in love, but they all learned of her illness after she had to be hospitalized due to the symptoms. While being treated, she realized her doctor, Scott Grainger, was actually the son of her ex-lover, Jim Grainger - making him Cricket's half-brother.

Despite her illness, John proposed to a hesitant Jessica until she ultimately accepted, and two months later, she and John were married. In early 1989, Cricket located Jessica's ex-lover and her father, Jim Grainger, and she arranged for him to come to Genoa City. She then got official proof of him being her father. With her condition worsening, Jessica's last wish was to reunite with her family: Jim, Scott and Cricket. John granted her a divorce, and Jessica and Jim married shortly before she finally succumbed to AIDS.
