It isn’t a great start to the day for Fenner. He’s about to get the all clear to resume marital relations after his vasectomy and to say that Di is raring to go would be an understatement. On top of this, he arrives on the wing to find that Neil has drafted in a PO from D-Wing he doesn’t like, Kevin Spiers. With Colin on suspension pending a police investigation, G-Wing is desperately short staffed. Neil has also decided that, now she’s resumed her hormone treatment, Arun should be returned to the wing.

Pat is off the hook for attempted murder and arrives back on G-Wing to receive a warm welcome from the women. However, Natalie and Janine are both fuming to see the return of this popular inmate, especially when she steps in to protect Arun from their bullying. Sensing that the wing is a powder-keg ready to blow, Spiers steps in to stir the mix and gathers a group of inmates together. He gives them each a notebook and asks them to spend the next few days recording their thoughts and concerns, making it clear that he is also uncomfortable with the idea of Arun’s presence on the wing.

Di decides to follow Fenner when he leaves for his appointment with his counsellor and is confused when she sees him entering the urology department of the local hospital. Quick as a flash, Fenner comes up with an explanation, devastating his broody wife by dropping the bombshell that he has a non-existent sperm count—her dreams of having children are over! Di is nothing if not resourceful and bounces back from his set-back by making an appointment at an adoption agency. It looks like Fenner is trapped, but during the interview, his revelations about the dangerous nature of his work ensure that he and Di won’t be approved as prospective parents.

Natalie is quick to see the advantages of Spiers’ plan and soon has the other women filling their notebooks with rubbish about Arun leering at them in the showers and making unwanted sexual advances. Upon reading the complaints, Neil feels that he has no option but to transfer Arun to a male prison. Arun is suicidal. How can she go on? Pat is furious that Natalie’s taunts and scheming have driven Arun so low and steps in to defend her. She rescinds her earlier refusal to fight Natalie and takes her up on her challenge, but under one condition—if she wins, Arun stays. The fight takes place in the gym with the two Julies acting as referees. Natalie gains the upper hand pretty quickly by employing under-hand tactics like sinking her teeth into her opponent’s ear, but she has made the mistake of underestimating Pat and finds that she might very well have met her match. Although it’s a close-run thing, Natalie is the one who is left bloody, battered, and out for the count.

Ex drug-addict and MBU inmate Sheena Williams is dreading the prospect of handing her baby son, Dylan over to Social Services—what if she never sees him again? After listening to Sheena’s tragic tale, Di steps in with a caring solution, offering to look after Dylan herself until the inmate’s release. Although Sheena clearly has reservations, she’s stuck between a rock and a hard place and feels that she has no option but to hand her baby over to Di. But how will Fenner react when he hears about what his wife has arranged to bring home?

Having conceded the role of top-dog to Pat, Natalie rather sheepishly offers the olive branch. Pat is suspicious, and rightly so, because Natalie doesn’t waste any time in suggesting that they join forces, even going so far as trying to kiss her in order to sweeten the deal. Pat’s too smart to fall for a move like that and ejects Natalie from her cell. Unable to stand the humiliation, Natalie vows that she will kill Pat and informs a shocked Janine that she’ll be helping her to do it.
