Hannah Wilson
Denny arrived in Summer Bay on the day of Ethan MacGuire's (Matt Minto) funeral, attracting scepticism and worry from Ethan's sister-in-law Hannah Wilson (Cassie Howarth), who wondered if she was a member of the cult that Ethan had been involved in. Smith said viewers would be surprised by Denny's true identity and teased "it's a bit of a family thing." It later emerged that Denny was Ethan's daughter. In her fictional backstory, Denny was raised by her single mother, but longed to find her father. She had trouble finding him, until she learned of his death. At the funeral, Denny learned that she had half-siblings, Evelyn (Philippa Northeast) and Oscar MacGuire (Jake Speer), and she was keen to form a relationship with them.
