Diane Hutchinson (also O'Connor) is a fictional character from the British soap opera Hollyoaks, played by Alex Fletcher. The character made her first appearance on 1 September 2010. Diane was introduced into the series by Hollyoaks executive producer Paul Marquess, during his rejuvenation of the show. Marquess axed numerous characters and replaced them with new families. Fletcher began filming in June 2010, the same month her casting was publicised. Diane was introduced with her husband, Rob (Gary Cargill) and stepchildren, Sinead (Stephanie Davis) and Finn O'Connor (Connor Wilkinson). The O'Connors are one of three families that were introduced 2010. Diane is characterised as a "loving wife" and a "devoted stepmum". Fletcher initially hoped that Diane would be likeable, despite her over the top demeanour. Fletcher believed Diane has a good relationship with her step-children and was loathe to portray her as "the wicked stepmother".
Diane's storylines originally focused on her fertility issues and subsequent In vitro fertilisation (IVF) treatment. Fletcher wanted to portray the storyline accurately because many women are affected by the issue. Diane's IVF treatment fails and she subsequently steals a baby from a hospital. Additional storylines include her divorce from Rob, dealing with Sinead and Finn's erratic behaviour, marrying Tony Hutchinson (Nick Pickard), giving birth to twins and the discovery that her and Tegan Lomax's (Jessica Ellis) babies were swapped at birth. Diane later develops obsessive–compulsive disorder. Diane made temporary departures in 2015 and 2016. In 2018, Fletcher and Pickard were nominated for "Best Partnership" at the Inside Soap Awards.
In 2010, Hollyoaks acquired a new series producer, Paul Marquess.[1] He embarked on the show's rejuvenation and axed a number of cast members.[2] [3] [4] Marquess revealed that new characters had been created to compensate for the departures.[5] Following the announcement of the new Sharpe and Costello families, Marquess told an Inside Soap reporter that a third new family would be introduced.[6] [7] The O'Connor family, described as a "four-member Liverpudlian tribe", were announced on 16 June 2010.[8] It was announced that Fletcher had been cast in the role of step-mother of two, Diane.[8] Gary Cargill was cast as Diane's husband, Rob, and Stephanie Davis and Connor Wilkinson were cast as her stepchildren, Sinead and Finn respectively.[8] Of her role, Fletcher said, "I am delighted to be back filming at Lime Pictures where I started my career on Brookside - then Mersey TV. I worked with Paul on Brookside and I'm thrilled and honoured to be working with him again, especially as this is such an exciting time for Hollyoaks."[8] Marquess commented, "We're very excited about the arrival of the O'Connors who burst onto screens in August with a very dramatic story-line. And I'm personally very excited to work with the fantastic Alex Fletcher again."[8] Fletcher began filming her scenes in mid-June.[9] She said working on the show is practical as she does not have to relocate.[9]
Diane is described as a "loving wife"[10] and a "devoted stepmum".[11] Fletcher told Daniel Kilkelly from Digital Spy that Diane is a good person because she has looked after two children who are not biologically hers.[9] In comparison to Jacqui Dixon, a character Fletcher played in Brookside, Fletcher assessed that Diane "hasn't got so much of a sting in her tail".[12] She added that Diane does not value her career as highly as Jacqui did and Diane is "a lot more sensitive and grown-up".[12] Fletcher described Diane as "a little bit over the top" in her initial stories, but hoped she would become "quite likeable" and relatable.[12] Diane is a marketing worker and is training to work for the local council.[13] [12] Fletcher explained to an OK! magazine reporter that Diane is the "rock of the family", adding that the O'Connor's are not a "dysfunctional family, they’re quite normal".[14] Fletcher also told Kilkelly of a great relationship between Diane, Sinead and Finn and loathed Diane becoming "the wicked stepmother".[12] She acknowledged that scenes often become "erring towards" Diane being annoyed with them, but ultimately writers portray her as a good step-parent.[12] In 2012, Fletcher told a reporter from K9 magazine that her own experiences of motherhood helped her to better play the motherly role of Diane. She revealed that Diane is "a really caring person but a bit nosey with it" because she is always keeping "a beady eye on" Sinead.[15]
A writer from the official Hollyoaks website likened Diane to a "professional racing horse" because "she never gets an easy ride" in storylines.[16] They detailed how being tasked with helping Sinead through young adulthood leaves her "worn out". They added that her need to support Sinead and Finn at times "made her unpopular".[16]
Diane becomes desperate to have her own child and undergoes a second round of In vitro fertilisation (IVF) treatment. Fletcher told the Liverpool Echo that she really wanted to get the storyline right because it affects so many people.[17] Fletcher added that she felt she had a "huge responsibility" to do the storyline justice.[17] The actress later explained that Rob is not that keen on having any more children, because he already has children.[9] Rob will do anything for Diane as she "pretty much stepped in and saved his life" with Sinead and Finn.[9] The storyline looks at how Sinead and Finn cope with the pressure and disappointment of IVF and the potential arrival of a new baby brother or sister.[18] Davis stated that Sinead is upset that Diane is desperate for a baby of her own. She said "I think she and her little brother are thinking, 'Well, aren't we good enough for you?' in a way."[19] Davis added that Sinead is against Diane's IVF treatment.[19] Fletcher called the storyline great because "there's just loads of avenues that they could take it down".[9]
Diane's second round of IVF fails and she breaks down.[20] Sinead comforts Diane, but Finn is glad as he "feels if Diane wants a baby it means she doesn't want him".[20] Diane is "desperate" for a baby,[9] and steals a baby boy from the hospital.[20] She goes to the hospital to see a nurse and when she gets there, she finds the baby.[20] Fletcher told a reporter from What's on TV that "the baby has been abandoned outside the hospital. Diane thinks it's an animal at first when she hears something crying - and when she looks it's a baby boy."[20] There is no information left with the baby, so Diane reasons that his mother does not deserve him and takes him home.[20] Fletcher explained that Diane takes the baby home rather than into the hospital because she believes that "she's doing the right thing and that she'll get in touch with social services."[20] But, Diane "goes past the point of no return" and feels a bond with the baby and falls in love with him.[20] Fletcher rationalised Diane's behaviour, stating "she's not a nut job. She's pumped full of hormones and the IVF hasn't worked. She's having a breakdown and she isn't thinking properly."[20] Fletcher recalled of her shock upon discovering Diane would take the baby. She envisioned Diane being "a good woman" and stealing a child out of character until she gained more context within the story. Fletcher defended her character, noting Diane does not "steal a baby, she finds a baby, and that's kind of different."[14]
In March 2016, Fletcher announced that she was pregnant and would be taking maternity leave from the show. This meant that the character had to be written out temporarily and she filmed the exit in May 2016.[21] Diane's exit storyline saw herself and Tony forced to sell their restaurant to Marnie Nightingale (Lysette Anthony) following months of her scheming to ruin the business. Diane and Tony return to working there but are treated unfairly by Marnie. Diane discovers that Marnie is having an affair with her daughter's boyfriend, Freddie Roscoe (Charlie Clapham) and blackmails her. Marnie decides she needs to get rid of Diane and calls an old friend who offers her a job in France, which Diane accepts.[22]
In 2021, writers explored the mental and behavioural disorder, obsessive compulsive disorder (OCD) via the character.[23] Announced on 8 April 2021 and promoted as an issue-based storyline, it was confirmed that Diane would develop the common mental health condition.[23] Fletcher described being entrusted with the story "an honour". She explained her intrigue and need to learn more about OCD. She noted that OCD is a widely known issue, but the severity of "how much it can inhibit people's lives" was lesser known.[23] Fletcher believed it was important to make the story factual and publicise the symptoms, especially as the Covid-19 pandemic made OCD more widespread.[23] The pandemic and constant government advice regarding hygiene and precautions made Fletcher unsure whether viewers needed to see such a story. But she noted Hollyoaks never "shy away" from playing current affairs despite their difficulties.[24] Fletcher told Sarah Ellis from Inside Soap that Diane suffered minor OCD symptoms when she was young and that this was added into the character's backstory. Diane had learned to suppress her symptoms until a series of personal traumas trigger her illness.[24]
Hollyoaks production partnered with the mental health charity, OCD-UK to ensure the story was portrayed accurately. Their aim was to get Diane "truly reflect an individual's experience of OCD".[25] OCD-UK worker Kirstie McBryan took an advisory role in the development of Diane's story, in which she liaised with Fletcher and story writers. McBryan distinguished that no televised drama can "fully explore all aspects" of OCD but Diane's story "captures the nuances of OCD as accurately as possible and shows the individual's suffering."[25] Ashley Fulwood from the charity added that OCD is more than cleaning rituals. He explained that untreated OCD rituals can have "devastating consequences".[25] He added that pregnant women's worries "can exacerbate OCD to the point of crisis, to the point of despair, to the point of desperation."[25] He concluded that this was Hollyoaks would explore with Diane and her pregnancy.[25] Hollyoaks decided to portray Diane's obsessive thoughts via voice overs, which was rare in televised OCD stories. These detailed what Diane was thinking, rather than just showing her compulsive behaviours.[26]
Writers used the aftermath of Diane's abusive relationship with Edward Hutchinson (Joe McGann) and her pregnancy to bring on her initial symptoms.[23] Fletcher assessed that Diane loves her family and blames herself for allowing Edward into their lives. She added that Diane "now feels an overwhelming need to protect them all and this comes out as obsessive behaviour, which is so consuming for Diane."[23] Diane's initial symptoms began surfacing the in her behaviour during episodes broadcast in February 2021. These included Diane checking windows and counting to 3, with the addition of reassuring herself nothing bad would happen via a voice over.[27] Stephen Patterson from Metro reported on Diane's behaviour and speculated the show was gearing up towards an OCD storyline.[27] Diane's scenes featured in May 2021 episodes explored her worsening symptoms. Diane covers all of her household furniture in protective sheets and asks Tony if they can go into a covid style lockdown. Her behaviour worries Tony and her sister-in-law Verity Hutchinson (Eva O'Hara), who then seeks medical advice from doctor Misbah Maalik (Harvey Virdi).[28] Fletcher explained that Tony originally believed Diane's behaviour was caused by hormones. Writers showed Diane using the covid pandemic and her pregnancy to mask her symptoms. Fletcher added "she's really frightened. She's reassuring herself and everyone else that once the baby comes, it's going to be fine. And she's desperate to believe that."[24] Tony realises Diane's condition is worse when following a marriage vow renewal proposal. Diane wraps her furniture in plastic to stop guests contaminating her home, but Verity recognises her symptoms as OCD. Fletcher described her behaviour as "extreme" but "Diane just can't help herself, it makes her feel better and makes the bad thoughts go away."[24]
By August 2021's episodes, writers displayed Diane's symptoms as severe. She becomes convinced a virus is spreading through the village and pours her businesses' alcohol stock away over contamination fears. Diane's extreme compulsions upset Tony, who informs her he cannot cope or help her overcome her illness alone.[29] In addition, Diane contends with her friend, Becky Quentin's (Katie McGlynn) downplaying of her illness. Writers used the development to urge Diane to seeks professional help for the first time and she arranges a hospital consultation.[29] Diane fails to make progress but during the October 2021 episodes, Diane finally begins treatment for her condition after giving birth to her daughter, Eva. She is portrayed as leaving the village temporarily to seek medical treatment, vowing to her family to return with better mental health.[30] Fletcher told Ellis that she hoped Diane's OCD storyline helped viewers struggling with the condition. She added "I hope this storyline can help shake off any stigma" and "will show that it is possible to recover with the right support."[24]
Diane completes a round of In vitro fertilisation treatment and takes a pregnancy test, which reveals she is not pregnant. She goes to the hospital to discuss other options for conceiving children and returns with a baby boy. Diane tells her stepdaughter, Sinead, that the baby was abandoned at the hospital. Diane intends to raise the baby, however he becomes ill and Sinead tells nurse, Lynsey Nolan (Karen Hassan). Lynsey discovers the truth but Diane refuses to hand him over.

For her portrayal of Diane, Fletcher was nominated for "Best Soap Actor (Female)" at the 2018 Digital Spy Reader Awards; she came in tenth place with 3.4% of the total votes.[31] Daniel Kilkelly of Digital Spy said he was "pleased" about Fletcher's signing.[12] A writer from Holy Soap recalled Diane's most memorable moment as "getting her step-daughter Sinead to administer her IVF injection when husband Rob was tied up at work."[10] The official Hollyoaks website ran a poll asking viewers which member of the O'Connor family was their favourite.[32] Diane received the most votes, with 1,597 (34.13%) people voting for her.[32] In another poll run by the website, readers were tasked with deciding who was the best mum out of Diane, Myra McQueen (Nicole Barber-Lane) and Martha Kane (Carli Norris). Diane came first with over 3920 votes, totalling over 51% of the vote.[33] In 2018, Fletcher and Pickard were nominated for "Best Partnership" at the Inside Soap Awards.[34]
A reporter from OK! magazine branded Diane a "confused character", "mixed-up mum" and "headline-grabbing role".[14] They assessed that Diane taking an abandoned baby from the hospital was a "compelling baby-snatch storyline".[14] Anthony D. Langford, writing for AfterElton, opined that Diane is an "atrocious mother" because of her behaviour during Esther's bullying storyline. Langford reasoned that Diane's behaviour resulted from parents always protecting their children. However, he believed Diane needed "to pay the price for her actions".[35] In 2021, prior to Diane's pregnancy being confirmed, Chris Edwards from Digital Spy reported on how fans had speculated that the character was pregnant due to her "strange behaviour".[36]
Sarah Wall from Digital Spy praised Diane's OCD storyline for showing "the reality of the condition and for thinking outside the box."[26] She noted that the use of voice overs was a "powerful tool", that allowed "viewers access to a character's most private thoughts".[26] She called it successful and portrayed the obsessive thoughts of OCD patients better than other shows had done prior. Wall added that the story took viewers "full cycle in her OCD world". Wall also praised the decision to have Diane, a "strong female character" portray the illness, adding "Hollyoaks has demonstrated how mental health disorders can affect anyone at any time in their lives."[26]
