As another week without the paradise of doomsday passes by, David focuses his attention on an as-yet-unfilled role as an elder within the church.

David unearths a 1000-year-old rule book of the Order and uses it to police his family; Fiona is inspired to break against sexist traditions and start her own business when she receives a useful gift, much to David's annoyance.

Rachel meets a supposedly pious girl at church who changes her perspective on dating; as David struggles to get Fiona's attention, he gets date ideas from the church's teenage sex education class.

Fiona's frustrations with David lead her eyes to wander down the road to Lycra-loving neighbour Andrew. David's confession about his Tupperware of Sin does not help matters.

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.

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.
