韋漢娜
In August 2013, further exploration of Zac's background began when his family were introduced. His sister-in-law Hannah Wilson (Cassie Howarth) came to Zac to ask for his help in rescuing their niece and nephew, Evelyn (Philippa Northeast) and Oscar (Jake Speer), from a cult that they have been inducted into by Zac's brother Ethan (Matt Minto). Howarth told "TV Week's" Jessica Grubb that Hannah and Zac had not seen each other in years, as Zac was estranged from his brother. Hannah had been helping to look after the twins following their mother's death. Zac initially thought Hannah was overreacting, but accompanied her on a visit to see his brother. Howarth observed that Zac did not see the cult for what it was straight away, as Ethan passed it off as a group enlightenment camp.
