Kevin's wedding approaches, but his big admission has far-reaching consequences. Cody is blindsided when her parents announce they are moving to Perth and want Possum to come with them.

Brad is about to be a dad; Britta's new object of desire leads to desperate measures and Leo; Cody receives some upsetting news from Eli; Kevin scores a date with someone he knew from school.

Our heroes are facing the end of their 20s — the downhill run which can only end in (oh god!) 30... For some it will mean one last stab at freedom; for others, time to try and settle down. But even best laid plans lead where you least expect them. This year, the quests are sorted. But has Kevin really found the perfect woman? And can Cody defend Gwen against a witch?

When Brad gets surprising news, Britta confronts the green-eyed monster. Kevin gets an offer that could ace his quest.

Kevin has family! But this particular cat causes havoc among the pigeons, and Cody needs cash for a good cause.

When it comes to love, a lot can change in a month — as Kevin, Cody, Olivia, Brad and Britta all discover.

Britta fears the end of true love when she finds that Brad hasn't told his mother about her and thinks Brad is embarrassed because she's not successful and smart like Amy and Angelina. Kevin's fears about Olivia turn out to be far worse than he suspected.

Cody deals with sex and sex bombs when she discovers that the nice young women she let Eli's house to, are in fact, the Laddettes from hell who have turned the place into a rat infested pigsty. Olivia finds her own life is a battleground as Jeffery and Carol clash over their very different approaches to Olivia's illness, and Olivia seeks refuge with her friends.

Kevin is facing the big 3-0, but Olivia raises bigger problems, and will Britta and Cody ever get rid of the cuckoo in the nest?

Cody is concerned for her mother who is having episodes where she worries about a troubled boy they used to foster. While Brad is off helping out Mia with the baby, Delilah, Britta gets some unsettling advice from the McMann women. She needs to keep an eye on her man.

Kevin has Amy staying and feels torn between the demands of his fiancé and his friend. Britta is upset to receive notice from a rival fairy company claiming copyright of her company name.

Does Kevin have a rival, or just a case of cold feet? And Cody's quest hits a very big hitch.

Kevin is having a stag party. Cody is upset to realise it's blokes only but Olivia points out that, as Kevin is getting married; everything is going to change. When Amy and Cody find Amanda measuring up Kev's kitchen for remodelling, it really hits home; its the end of an era. Britta is getting on with her fairy empire and hires an extra-young fairy, to Nan's chagrin. Britta admits to Leo that she's lonely and he takes heart from this to make a serious move on her. Cody is avoiding NSB because she worries it's all too complicated. He comes to see her and suggests a date. Although still uncertain, she agrees. But then she has to cancel for Kevin's pre-wedding piss-up. Events take over with Olivia's sudden illness and Cody finds herself turning to NSB for comfort.
