Izzy arrives in Ramsay Street to visit her brother Max Hoyland. She moves in with Karl Kennedy (Alan Fletcher) after he breaks up with his wife Susan (Jackie Woodburne). She claims that Karl is the father of her unborn baby, when it is actually Gus Cleary's (Ben Barrack). Izzy has a miscarriage and breaks up with Karl. She then forms a relationship with Paul Robinson (Stefan Dennis). Darcy Tyler (Mark Raffety) discovers that the pregnancy dates do not add up and threatens to tell Karl. Izzy tries to pay him off, but he refuses to take any money. During the confrontation, Darcy falls down a flight of stairs and ends up in a coma. When he wakes up, he begins to play mind games with Izzy. Darcy forces her to give him a favourable testimony at his court hearing. Darcy then reveals the truth to Susan in a letter and she forces Izzy to tell Karl that he was not the baby's father. Karl kicks her out and she disappears, leaving Paul under suspicion for her murder. She is found alive and Paul's name is cleared. Izzy overcomes a drug problem and she and Paul move in together. Paul's daughter Elle (Pippa Black) also moves in and she takes an instant dislike to Izzy. Elle tries lacing her food with drugs to convince Paul that Izzy still has a drug problem.
