1.08 Sins of the Fathers by Peter Pinney
Summary: Violet's organising a fancy dress party. A woman with airs shows up at a clinic with her pregnant niece, but something seems fishy. As it turns out, the pregnant young woman isn't a niece at all, but a woman who has got paid to be a surrogate mother to a childless couple. The would-be father actually did the deed himself, rather than insemanating her. They didn't go for an adoption because "people would talk". In Coopers Crossing, a mum with a whole horde of unruly children has come to give birth to yet another one, and the townsfolk have to look after the five kids she's brought with her. When babysitting, Ron shows them his own special crackers, and in a bid to save the youngest child from getting blown up by one, he throws himself over the home-made bomb as it explodes, rendering him unconscious and badly injured. After giving birth, the surrogate mum decides to take the baby and run, but eventually is persuaded to see reason and hand the baby over to his father. The fancy dress party goes ahead like planned, and everyone says good-bye to Ron, who is flown to Sydney for special treatment.
