A new client forces Heather to realise that beneath her liberal facade she does have certain boundaries. Spurred on by a car salesman client and looking for some adventure, Lauren buys herself a new car and becomes a lead foot. Tippi takes on Martin, a client who made Chloe distinctly uncomfortable, and whilst working at 232 fixing the sound-system, Josh is confronted by the reality of Chloe's work. Sensing he's troubled, Tippi's on hand to distract him.

Mel receives an untimely visit from her brother Sean, whose arrival in her life usually signals trouble. Tippi invites Sean to look around 232 and meeting Nat makes his head spin and he begins to consider a career change. Tippi has a frightening session with Martin whilst Lauren has a surprising encounter with her ex-husband's best friend Max. Trying to remain buoyant, Chloe prepares Bonnie for boarding school.

Mel has a new client, Marc, who is very young and very eager. Confident, fun, and with access to plenty of money he makes her feel invigorated and is precisely the frivolous diversion Mel needs in her life at the moment. Nat becomes aware she has feelings for Sean and Heather's having trouble disengaging from Jack, overwhelmed by the heterosexual feelings he continues to unleash in her.

With Sean's intentions now out in the open, fantasy and reality are blurring for Nat. Provoked by a particularly intimate gesture from Sean, Nat realises she needs to make a step towards a real human connection. Mark refuses to accept that, given particular circumstances, things are over with Mel, while Chloe is missing Bonnie more than ever and discovers her daughter is feeling the same. Meanwhile, after returning home into the eye of a media storm, Lauren is introduced into high society by Mel - and she is treated like a star.

Bernie, an off-kilter fetish client of Heather's lands at 232 wanting to see her. Desperate to get rid of him, Nat makes a false promise to find him a replacement, but Bernie's not going to go away that easily.

In the pursuit of normal couple dating, Sean takes Nat to the movies where she's like a fish out of water. While Sean thinks it's fun, Nat finds it excruciating. The concept of 'us' is not something that sits comfortably with her and she tells Sean she wants an open relationship.
