After Maddie answered a call from an estate agent, Elizabeth revealed that she and Ed were filing for divorce and selling their houses in Hollyoaks and Abersoch.
In September 2012, Elizabeth was called into Hollyoaks Sixth Form College after headteacher Mr. Keeler caught Maddie fighting with Phoebe McQueen. Afterwards, Elizabeth flirted with Rhys and offered to buy him a drink, which Rhys accepted. Elizabeth seduced Rhys, but he made a quick getaway. A few days later, Elizabeth encountered Rhys in College Coffee and flirted with him, angering Rhys's mistress and boss Cindy Cunningham who started a fight with her.
