Alison has decided to call the divorce off. The girls organise a surprise second honeymoon for their parents in the Lake District - in the same hotel where they spent their first. But Virginia has also invited Graham and his wife Helen - and Alison has a secret to reveal about him; is this the end of the Braithwaites' marriage. Back at home, the girls need cheering up after a terrible day, but during a food fight, Sarah goes into labour, and it's up to Virginia to be her birth-partner - until the child's father, Phil, turns up.
