When Sharon first arrived in Genoa City as a high school senior, she began dating Matt Clark (Eddie Cibrian), but couldn’t get Nicholas Newman out of her mind and he couldn’t get her out his mind. Eventually, Sharon broke up with Matt to date Nick and the two fell so much in love that they insisted on getting married right out of high school, much to Nick’s mother, Nikki Newman’s (Melody Thomas Scott) chagrin.
After Sharon became pregnant and gave birth to her and Nick’s son, Noah (played as an adult by Rory Gibson), prematurely, her old friend Grace Turner (Jennifer Gareis) arrived in town with a secret. Nick finally learned that before Sharon moved to Genoa City, she had given birth to a baby girl she placed up for adoption. Grace was determined to find the child and bring her to Sharon in case she lost her son. It turned out Cassie’s (Camryn Grimes) adoptive mom was happy to give her up, and Nick and Sharon ended up raising her legally as their own, along with Noah who lived.
Sure, Sharon had a few affairs, first with Diego Gutierrez (Diego Serrano) and then Cameron Kirsten (Linden Ashby). Still, she and Nick managed to keep it together until a teenage Cassie was killed in a car accident when she took the wheel without a license to drive for a drunk Daniel Romalotti (Michael Graziadei).
