Shortly after Alf suffers health problems and decides to cut Duncan out of his will, Duncan comes to visit him, but does not receive a warm welcome. Duncan's return marked the first time in 27 years that he, Alf and his half-sister Roo Stewart (Georgie Parker) have been on screen together. Duncan also befriends Tori Morgan (Penny McNamee) and develops "an immediate connection" with her, but ends up competing with Nate Cooper (Kyle Pryor) for her affections. Wall had worked with Pryor before they were cast in the show, and he quipped, "now we're competing for the same woman."
