Blake has a new girlfriend meaning Susan is even more at a loose end than usual. Unfortunately, it's time Susan chooses to spend irritating Fiona.

In a bid to occupy her, Fiona introduces Susan to some of her work friends but her attempts to control Susan's behaviour are ignored and Susan is soon proving herself to be a social liability – or at least in Fiona’s eyes. From Susan’s point of view, she has become the life and soul of the party.

It becomes a battle for the friends' attentions, with Susan and Fiona each attempting to prove they are the more fun sibling. Meanwhile, Blake's relationship with hipster girlfriend Martine gets seriously challenged by a resentful Susan .
