When Belinda comes home from her women's group, with a Safe Sex board-game, Chloe decides that everybody in the house is unhealthily obsessed with "It". Sex, that is. Trev has fallen in love with Lucy and is grumpy because they can never be alone, and Jack is in a dither because she's met someone new. Far worse, Mike has started seeing Chloe's mother again and there is talk of a reconciliation. And then, when VJ climbs in through Robert's window in search of a friend because her dog has died, everybody presumes they've spent the night together. As Chloe begins a crusade to put the household back on the straight and narrow, everybody else is going through the painful business of sorting out their relationships.
