Izzy has an affair with Ned Parker (Daniel O'Connor), which is initiated in an attempt to get him out of Erinsborough, which both Robert Robinson (Adam Hunter) and Lou Carpenter (Tom Oliver) find out about. Robert later moves in with Izzy and Paul, while pretending to be his identical twin brother Cameron. After she became suspicious of Robert's behaviour, Izzy tries to convince Paul and Elle that he is responsible for the 'accidents' she was said to have caused, such as leaving the gas on while babysitting her nephew Charlie. Everyone believes that she is just being careless and hysterical and Paul eventually throws her out. She gets Paul and the police to believe her after she discovers that Robert had been recording her phone conversations and editing them on his laptop. After Cameron is cleared of all charges, he too moved in with her, Elle and Paul. Paul and Izzy's relationship begins to decline and when Paul is caught cheating on her, she breaks up with him.
