TVGuide reports that Darla will make several ghostly appearance to her daughter Aly.
The wildly popular Harrison exited B&B in 2006 when Darla was killed in a hit-and-run accident. While attempting to change a tire on a car, Darla fell backwards into the road and was struck by the car. Darla later died of complications from severe head trauma.
Fans learned that a drunken Taylor was the driver of the car, but Taylor was convinced to keep quiet about her involvement. Eventually, Taylor confessed and stood trial, but a witness came forward to say that Darla has fallen, and Taylor was found not guilty.
Harrison made her first appearance on The Bold and the Beautiful in 1989 in a recurring capacity. She exited the role in 2006, but the actress returned for a two-day appearance in 2007 when Thorne had visions of his late wife's face.
For now, Harrison is expected to make three appearances, the first on March 18.
