The Young and the Restless
With the success of another iconic character, Kimberlin Brown's Sheila Carter, Bell successfully crossed her over from "The Young and the Restless" to his second soap, "The Bold and the Beautiful", in 1992. The success of the crossover was due to the creativity of Bell, as the nefarious character of Sheila was presumed to have died in a fire on "The Young and the Restless".
