 Actor Jamie Davis decided to leave his role as Max Walker in 2017 and called former co-star Sunetra Sarker, who portrayed Max's estranged wife Zoe Hanna for eight and a half years, to ask her to reprise her role for his departure, as part of a deal they made when Sarker left the drama in 2016.Sarker had forgotten the agreement when Davis contacted her, but agreed to return for one episode nevertheless.She said that returning for Davis' exit is very important to her due to the close relationship that the actors share.
