Callum tries to help his friend Sophie

With Kate refusing to come home, Sophie seems to have run out of options - the DHS will inevitably take her into foster care. Having previously fought with Kate, she's too proud to contact her again, so Callum decides to step in, sending an email to Kate pretending to be Sophie, and begging her to come back. But when Karl seems to confirm Sophie's fears that Kate will not be coming home, Sophie decides to pack her bags and run. Meanwhile, Kate embraces her decision to go traveling with Dominic. They plan to spend a last day in Port Douglas together before heading off to Vietnam. But then Callum's fraught email arrives, which Kate believes is from Sophie, explaining that the DHS will take her into foster care if Kate doesn't come back. Kate is forced to choose between her new boyfriend, and their shared dreams of travel, and her little sister back home. As Sonya frets over the results of her fertility tests, Toadie plays the wise and supportive partner. But when Rhys reveals that Toadie's the one with fertility issues, Toadie is totally thrown. Despite Karl's advice and Sonya's support, Toadie's got some hard yards ahead.
