What Lies Beneath - S4.E1

It's been three months since Ben and Nathan left on their road trip around Australia. Bearded and tanned, Ben returns without Nathan and smooths over his family's concern with a plausible excuse. He believes that if he wants to fit back in with his family, he has to be the fun loving guy he was before Melissa died.

At home much has happened. Coby has moved in with Jake and started his apprenticeship with Dave. Ruby has started walking and the house has been baby-proofed. Carbo and Retta's engagement party is fast approaching but it's the anticipated arrival of Rita – and what she'll say about the new relationship – which is causing nervous diarrhoea for Carbo and dry-retching for Retta.

As the family and the Karandonis clan celebrate his return, Ben is upbeat. Even the sight of the cheque for Mel's life insurance doesn't seem to faze him – but a visit back to his old room in the Karandonis house proves how much emotion he's really hiding. Unwilling to worry his family, Ben manages to seamlessly manipulate Rachel into offering her room, happy to stay more permanently with Jake and Coby. But will Ben be able to fool his mother Julie?
