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.

While David returns to the old house, Graham tries to woo Alison, but she'll not be persuaded that easily - will she? Tamsin sways Virginia into revealing their relationship, but she is no way prepared for the thunderous reaction, and ends up in a passionate kiss with Megan. Phil and Sarah go into Leeds to get married in secret, but afterwards, she has second thoughts. But what she sees at the old house is a surprise, and David has a surprise to tell her about her mother too.

The Braithwaite family seems fragmented for good, as Sarah and baby William move in with David. Charlotte's determination to get the family back on track involves a appearance on a TV quiz show, but Alison refuses point blank - they're no longer a 'normal' family. There's an expensive offer for Virginia to make to Megan in the aftermath of the drunken previous night and Alison finally meets up with Graham. He tells her he's in love with her too, but she refuses to have an affair with him and put another woman through that sort of pain. But he and Helen are getting a divorce, so she relents, and they begin seeing one another. But someone is watching them.
