In 1996, Ralph became a series regular on the teen sitcom Moesha, playing Dee Mitchell, Brandy's stepmom.
Though the show ran for six seasons, the award-winning actress exited after five, after a dramatic plot twist that saw her onscreen husband Frank (William Allen Young) reveal that he secretly had a son, Dorian (played by Brandy's real-life little brother, Ray J).
"That was another incredible working environment until it wasn't any longer," Ralph told the AV Club in 2022. "I was free to be an artist. It was a great learning experience for me, and an incredibly human one, as well"
She continued, "One of the greatest lessons I ever learned from it was knowing when it's time to leave the room. I believe in the power of a warm and wonderful Black family, because it is something we do not get to see enough. And for them to take that family and literally just ruined the family by calling the father a liar [by revealing past infidelity] ... why do this? Why destroy this family?"
She alluded that there were some people in the background pushing for a scandalous storyline. "There were people within the group that said, 'Oh no, we've got to destroy it because these people are just too goody-goody. We don't have Black people like that.' They had drank the Kool-Aid. But oh my, when it was good, it was great."
