Cath finally stands up to Jill and throws her out of the house and reveals some interesting news to Jill. Jill goes ahead with Terry's funeral, inviting Cath & Don, however there is one guest Jill did not expect.

Meet Jill (""mid 20's, widow, with a lust for life and a flexible spine""), a suburban hairdresser who sets her sights on a new life following her husband is diagnosed with cancer. Jill convinces everyone her husband Terry is dead, however he's alive and well in the hospital. But Jill doesn't care about that, she's got better things to do like joining the ""Lasso the Moon"" Matchmaking Agency where she's set-up on a rather peculiar blind-date with Glen who describes his personality as ""Scottish"". Next on the agenda is the ‘Fun and Fellowship' group at the local village hall where she meets her new neighbour and the man of her dreams - Dr. Don Cole. Jill firmly sets her sights on the dishy GP, but there's just a slight problem - he's married to wheelchair-bound Cath. Undeterred by this small obstacle, Jill infiltrates their lives…and refuses leave.

Jill descends further into Cath and Don's lives by inviting Don around for a dinner of smashed prawns in a milky basket. However her plans are thwarted when Cath turns up for dinner too. Meanwhile, husband Terry continues his attempts to get in touch, but Jill still refuses to speak to him.

Don and Cathy split up. Jill kills Terry, then forces Glenn to kill Gordon the vicar with a poisoned sundae and makes him confess to the police. Then she tells them him they can start a new life- well death together. He eats one of the other poisoned desserts, then gives it to her, saying it's her turn. She tells him she's not really hungry and watches him die. Terry turns out to be alive after all.

Jill convinces Cath to try to heal her marriage with the Caro Bibbens Celebrating Celibacy programme. Don becomes increasingly frustrated and is eventually thrown out of the house by Cath after she finds a pair of lacy split pants in his pocket.

Don attempts a reconciliation with Cath but Jill is now firmly established in their home and has no intention of allowing the two to make up. Meanwhile, Terry is released from the hospital and Jill puts him straight into a hospice where he assumes he'll spend the last days of his life.
