At an annual cross-church party, Aaron waits to be baptised. But his head is turned by one congregation carrying rainbow flags. Fiona and Rachel argue over university.
David takes Aaron to a caravan for some father-son bonding, but there's no electricity and the only running water is leaking through the ceiling. Fiona hosts a girls' night.
Fiona's frustrations with David lead her eyes to wander down the road to Lycra-loving neighbour Andrew, and David's confession about his 'Tupperware of Sin' doesn't help matters.
Rachel meets a supposedly pious girl at church who changes her perspective on dating. Struggling to get Fiona's attention, David gets date ideas from a sex education class.
