Overview: Ben begins to feel like the victim in a horror film who always goes where the audience knows he shouldn't as he begins to question Melissa's commitment to being a parent. Don't go there! When Melissa feels queasy during dinner, Ben immediately assumes she is pregnant and is beside himself with excitement. But Melissa seems hesitant and confused by the possibility, putting off using the pregnancy test kit until the morning and rebuffing Ben's attempts to open up about her feelings. Next door there's little rest and relaxation for Dave who is working extra long hours, saving up for a holiday to Fiji. But his plans cop a setback when an unexpected tax bill lobs on the doorstep. Rachel marches off to an important pitch meeting buoyed by Jake's encouragement. Inexplicably, the client rejects all of Rachel's ideas. What she hasn't yet realised is that oily colleague Liam is sabotaging her efforts. Will Rachel unmask Liam's duplicity? Or will he get the better of her? Meanwhile, Carbo's diet of horror movies has primed him for his own supernatural encounter, and he becomes convinced Mrs. Luscombe's sad, empty house is haunted. His nervous reaction is gold for Nathan who mercilessly revs Carbo up. But the final reveal of "the ghost" next door takes everyone by surprise! Carbo's relationship with Retta continues to bloom, and he hosts a dinner party in an effort to bond her with his housemates. After a painfully hilarious evening, the night ends with a startling announcement from the lovesick pair – one that sends Ben into meltdown. To top it all off, Carbo's mum rings with news that plunges the whole household into uncertainty about the future – she is selling the Karandonis house!
