Natalie is down the block after the discovery of the pair of scissors that were planted in her mattress by Di. With most of his officers calling for Natalie to be shipped out, Fenner finds himself in an awkward position, especially when she threatens to send her soiled knickers to the police. Under the guise of requesting a new change of clothes, Natalie summons Janine down to the block and talks her into taking the rap for her. Before long, Janine is confessing to a relieved Fenner that she planted the scissors in Natalie’s cell to get back at her. Di of course knows better and objects in the strongest possible terms when Janine is taken away to swap places with Natalie.

A tough new inmate, Pat Kerrigan is transferred to Larkhall from another prison. Fenner can spot her nuisance potential almost immediately and it seems as though he may be right when she commits the cardinal sin of stealing Natalie’s lunch. But when Natalie arrives to put Pat right, it seems that the new inmate is preoccupied with the sight of Sister Thomas. And, when the nun disappears into her cell, Pat dashes to the servery and smashes the knife cupboard with a fire extinguisher before any of the POs can react. A matter of minutes later, she is holding Sister Thomas at knifepoint on the G2 landing.

The other inmates look on as Pat forces Sister Thomas to strip down to her underclothes. They’re all appalled by Pat’s behaviour—how dare she take their friend hostage? But it soon transpires that Sister Thomas isn’t as saintly as she appears when Pat reveals the extent of the horrific abuse she and her friend, Lucy, were subjected to at the children’s home run by the nun and a priest, Father Kelly. After displaying the scars on her back she claims Father Kelly inflicted, Pat orders Neil to bring the priest to Larkhall. If he doesn’t, she’ll slit Sister Thomas’ throat.

While Fenner disappears to find Father Kelly, Pat starts reading aloud from Lucy’s diary. As they hear the heart-breaking words, the mood of the wing becomes more sympathetic. The mood turns to anger when Father Kelly arrives. He has no qualms in admitting that he had sex with Lucy—after all, she had been working the streets as a child prostitute before being sent to his home. The rest of the women listen on in horror as he reveals that Sister Thomas used to encourage him to sexually abuse the girls in their care so that she could watch. As the evil nun finally reveals her true colours, Pat drops the knife and is immediately pounced on by the POs. Colin plants a headbutt on Father Kelly and has to be restrained while the women throw every available missile they can get their hands on at Sister Thomas. As Pat is taken down to the block, Sister Thomas is shipped out.

It’s the day of Hollamby and Dr Nicholson’s wedding and, as everyone else prepares for the ceremony, Neil ties up a few loose ends on G-Wing, namely, Arun’s adjudication. He has a surprise in store when Arun walks into his office with her face hidden behind a jumper. She is so disgusted by Sister Thomas that she has decided to forgo Catholicism for Islam. Although Neil is unable to object, Natalie is quick to pounce on Arun’s return to the wing. She rips away the jumper to reveal a full beard!

Hollamby and Dr Nicholson exchange their wedding vows and they are both thrilled to have done it. Hollamby is now a blushing bride and can’t wait to start married life with her lovely doctor. But, as she is whisked off for a turn on the dancefloor, she is unaware of the fact that Dr Nicholson is only after her money. The groom isn’t the only one with his eye on the bride’s inheritance—now that he’s done his duty and given his mother away, Bobby Darren Hollamby is angling for his mother to put up the deposit on a flat he has his eye on. As she’s now practically penniless, Hollamby has no option but to refuse. Bobby Darren begins to shed his disappointment when he catches the bride’s bouquet, and later, he sheds all of his clothes before climbing into bed with Neil!
