Once Jade and Seb leave the Bay after the accident, Alf and Morag try to get Duncan to settle back in and send him to Summer Bay High, where he is unpopular. He antagonises Robbie and Kim Hyde (Chris Hemsworth) and begins harassing Tasha Andrews (Isabel Lucas) when he learns that her biological mother was the late Angie Russell (Laurie Foell). After pulling a gun on Kim and Robbie, Duncan leaves to join his half-sister, Roo (Justine Clarke; Georgie Parker) in New York City. Duncan later contacts Alf with the news that Roo has been involved in a car crash and is in a critical condition. Alf flies out to join them.
