In 1979, at the age of 23, she left The Waltons to take over the role of Nikki Reed, a poor girl from the wrong side of the tracks, on the daytime serial The Young and the Restless, choosing the part over a sitcom pilot that in the end was not picked up. She was a replacement for the previous Nikki, who had lasted six months. Over time, her character reformed and became an important part of Genoa City society, as she married Victor Newman (Eric Braeden). Scott has said, "It's a miracle for an actor to have a job last 35 years. I am so blessed."
