The existence of the house is under threat when a housemate decides to move out and the gang discovers that replacing them is virtually impossible.

Hosted by Harry, Manju is already somewhat sullen at her seventieth birthday gathering, when an errant comment subsequently leads to that sullenness turning to belligerence specifically toward Harry. Manju, being her manipulative self, makes a pronouncement intended to make Harry feel guilty enough to apologize, that pronouncement which Harry doesn't believe she will carry out to its end, Harry in turn calling her bluff. Feeling like he has perhaps gone too far, he is convinced by Heather to double down on that bluff or else have her know that she will always be able to manipulate him. With those plays going into night leading to both Harry and Manju having little to no sleep, something happens in the morning to change the face of their standoff. Meanwhile, Stuart is on his way back to Melbourne on a business trip, Liz who, on their last telephone call, stating that they need to talk in Stuart's belief that she had an affair. Liz has to decide exactly how she is going to broach the topic of the "issue" with him. And Ben is finally going on a date about which Ainsley discovers. It isn't so much that he has this date, which he doesn't see as such, but who the date is with. Regardless, Ainsley in particular has to decide if or what to tell Heather.
