Dom arrived to visit his sister
Toni (Laura Hill) and quickly got a job at the hospital. He mysteriously got on well with rival
Chris' (
Michael Galvin) mother -
Margot Warner (Dinah Priestley) and when she died, Dom revealed himself as Chris' illegitimate half brother. Taking up the Warner surname, Dom married
Emily (Sarah Somerville) and fought attractions to teenager -
Delphi Greenlaw (
Anna Hutchison). Following a blood test, Dom realized he was not related to Chris but kept it a secret whilst he started an affair with Delphi. To hide the affair, he drugged his wife and soon became a suspect in the murder of
Geoff (
Andrew Laing) who had discovered the affair. Once Chris discovered the truth, Dom circulated rumours he was a child molester. Dom and Delphi planned to run away but Delphi discovered Dom had killed Geoff and a desperate Dom fled Ferndale. Dom returned later in 2004, having started a relationship with
Lucy (Sally Stockwell). He managed to successfully avoid capture in relation to Geoff's murder and when
Avril (Kate Louise-Elliot) began snooping, he drowned her in his bath tub. When the staff started to turn against Dom after Avril's sister
Bernadette (Kate Louise-Elliot) accused him of murder, he faked mental illness and after escaping a psych ward, he lured Chris to a barn and tried to set him on fire. Unsuccessful, Dom ended up getting caught in a large explosion. With intense burns, Dom finally admitted to killing Geoff and Avril before he died in Toni's arms. ==Character development==
