Dylan was the third member of the Timmins family to be introduced, following his younger brother Stingray Timmins (Ben Nicholas) and their mother Janelle Timmins (Nell Feeney). Prior to his arrival, Dylan was serving time in juvenile detention for a robbery. He decides to visit his brother in Erinsborough rather than return to his home in Colac. Bodie called his character "the black sheep of the family – definitely more of an outsider than Stingray." He explained that Janelle did not love Dylan as much as his siblings, which caused Dylan to pick on Stingray, who just sees him as the older brother who "bashed him up." Dylan tells Stingray's guardian Susan Kennedy (Jackie Woodburne) that he is close with his brother, but when Stingray returns home he punches Dylan. Bodie said Dylan is jealous of Stingray's new home life and he is also attracted to his girlfriend Serena Bishop (Lara Sacher). He joked, "Dylan will basically go after anything with two legs. His eyes pop out of his head when he sees Serena. He can't believe Stingray has done so well for himself!" Susan invites Dylan to stay, much to Stingray's displeasure, and she has to play "peacemaker" between them. Dylan insists that he has changed, but Stingray suspects that he is out for what he can get.
