to be released, which she did, while she and Matthew quietly plotted their revenge. When the truth was revealed, Grayson threw Rosemary out. Not feeling safe at Mill Cottage, Perdita was staying at Home Farm and Matthew hoped it would become permanent but Grayson told her that he'd thrown Rosemary out and convinced her to go home with him. The next day, Perdita saw Rosemary in the pub and revealed to everyone there that Rosemary was the cause. Rosemary told everyone that Perdita didn't know what she was saying but admitted the truth to Zak Dingle (Steve Halliwell). She was shocked when even he thought her behaviour was disgraceful.

Katie, learning that Perdita and Grayson's marriage had collapsed, promptly threatened to have a termination as she was not surrogate for Perdita and Matthew. Horrified by this, Perdita blackmailed Grayson again to make sure that Katie
