Agnes Tinker, played by former Last of the Summer Wine actress Juliette Kaplan, made her first screen appearance on 5 January 2015. The character and casting was announced on 21 December 2014. Kaplan was initially set to appear in four episodes, but this was later extended to eight.

Agnes is Beth Tinker's (Lisa George) grandmother, who comes to Weatherfield for her wedding to Kirk Sutherland (Andrew Whyment). She arrives with her daughter Nancy (Kate Fitzgerald) and her granddaughter Arlene (Alison Burrows). The women initially mistake Jason Grimshaw (Ryan Thomas) for Kirk and are disappointed when Kirk does eventually turn up. Agnes tells Arlene's daughter, Sinead (Katie McGlynn) that she will leave everything to her when she dies. Believing Kirk is not around, Agnes, Nancy and Arlene start making unkind remarks about him and his job. Beth and Kirk get married and Agnes leaves after the reception.

A few weeks later, Sinead is badly injured in a minibus crash and Agnes returns to the Street. She attempts to calm Chesney Brown (Sam Aston) down, after he is involved in a confrontation with Steve McDonald (Simon Gregson). Agnes visits Sinead and decides to stay for a while to help out.

Michelle later changes her mind and they go to the bistro nearby. Michelle tries to keep their relationship professional, as she is just getting over her break-up with Steve McDonald (Simon Gregson). However, she and Hamish soon begin dating. After Michelle is involved in a minibus crash, Hamish comes to the Rovers to see her. When he learns of her intentions to get back together with Steve, Hamish leaves.

Michael Cregan from Inside Soap observed "There's a gleam in Michelle's eye tonight as she meets handsome new client Hamish. It's not hard to see why, as he's played by the lovely James Redmond". Caroline Corcoran from the Daily Mirror liked the character and felt sympathy for him when Michelle reconciled with Steve. Corcoran said "Oh Non Scottish Hamish! Poor Non Scottish Hamish. The most well-rounded, normal, least psychotic man to arrive on the cobbles in at least 20 years and he's binned off in the space of five dates, via that well-known break-up method where you get your ex boyfriend along to hold your hand and hope that your new boyfriend gets the message." Corcoran hoped Hamish would return and become a love interest to another character.

Linda Hancock (also Armstrong), played by Jacqueline Leonard, made her first screen appearance on 9 February 2015. Leonard's casting was announced on 18 November 2014, while the character has previously been mentioned by her on-screen family members. Of joining the cast, Leonard said "I am incredibly honoured and excited to be joining the amazing cast of Coronation Street. I love the Northern wit and humour along with the drama and tension that the wonderful scripts of Coronation Street encapsulate. So excited to start!"

Linda is established character Owen Armstrong's (Ian Puleston-Davies) ex-wife and the mother of Izzy (Cherylee Houston) and Katy Armstrong (Georgia May Foote). She will come to Weatherfield from Portugal to try and develop a relationship with her daughters, with whom she has not had contact in years. However, Izzy and Katy "believe it's far too late to build bridges", as Owen told them that Linda walked out on them as young children as she could not cope. Daniel Kilkelly from Digital Spy reported that it soon becomes clear Owen has not told Izzy and Katy the whole truth. Linda's presence will also test Owen's relationship with Anna Windass (Debbie Rush).

Owen is horrified when Linda arrives out of the blue from Portugal, where she has remarried and divorced again, to see her daughters. Izzy recognises her and is equally upset by her arrival; however, Katy, who was much younger when Linda left, is intrigued to find out more about her mother. Izzy remains hostile as she believes Linda left because she couldn't cope with having a daughter in a wheelchair. She is shocked when Linda forces Owen to admit that this wasn't true and that he said it in revenge for Linda having an affair. Linda also reveals Owen blocked her attempts to have any relationship with her daughters after she left. After this, Izzy begins to warm to Linda and she and Katy enjoy spending time with their mother. Upset at the idea of leaving them when she returns to Portugal, Linda asks both her daughters to come to live with her there. Izzy says she can't take her son Jake away from his father, but Katy is tempted, despite being in a similar situation with her own son, Joseph. When Owen confronts Linda, she admits she still loves him and asks him for a second chance, suggesting he follow them to Portugal. Owen refuses, saying he loves Anna. Linda is upset but delighted when Katy, after being dumped by Callum Logan (Sean Ward), opts to take her up on her offer. Linda returns to Portugal with Katy and Joseph.

Gavin Rodwell, played by Mark Holgate, made his first screen appearance on 2 March 2015.

Gavin is Michael Rodwell's (Les Dennis) real son, his friend Andy Carver (Oliver Farnworth) having pretended to be him.

Andy's girlfriend Steph Britton (Tisha Merry), the only person who knows his secret, goes to his flat and finds Gavin there. She explains that she is Andy's girlfriend and Gavin makes her stay for a drink. He tells Steph that he has just returned from Thailand and he lost his phone abroad, so he has not been in contact with Andy. Steph and Andy later try to remove any evidence from the flat; however, Gavin finds a payslip from Nick's Bistro in his name. Andy tries to tell Gavin he used his name to avoid his wages being used on his overdraft but, aware Gavin deserves to know about Michael's hereditary heart condition, admits the truth. Despite Andy pointing out that he could have the same condition as Michael, Gavin is not interested in seeing his father or finding out more, being still bitter about Michael leaving him as a child. Andy worries the shock of learning the truth could kill Michael and begs Gavin to keep quiet. Gavin tells Andy that he will - in exchange for £5,000.

When Andy takes the bistro's takings to the bank, he and Steph fake a mugging in order to give the money to Gavin. However, it isn't enough, and Gavin opts to blackmail Michael's fiancée Gavin's appearance saw him blackmail Michael's fiancée Gail McIntyre (Helen Worth) instead. Gail is horrified by Andy's deception, but agrees to pay Gavin off to protect Michael. Gavin then plans to return to Thailand, but he crashes his car and dies soon afterwards. Having seen Gavin had been drinking, Andy and Gail believe Gavin simply lost control of the car. However, Michael's aunt Barbara Deakin (Beatrice Kelly) later visits Gail and reveals Gavin had a heart attack at the wheel, meaning he inherited Michael's heart condition.

Jackson Hodge, played by Rhys Cadman, is the father of Faye Windass' (Ellie Leach) baby, Miley Windass (Erin, Eliah and Elsie Halliwell). He first appeared in the episode broadcast on 4 March 2015, before departing on 24 June 2015 with Miley and his parents. He returned with Miley on 17 March 2017.

Jackson first appears when Faye and her parents, Anna Windass (Debbie Rush) and Owen Armstrong (Ian Puleston-Davies) sit next to him and his parents, Greig (Stuart Wolfenden) and Josie Hodge (Una McNulty). Jackson is confirmed as the father of Faye's baby Miley, after she gives birth in an abandoned flat in April 2015. However, Jackson denies that he is Miley's father, even though he is, when Anna calls Greig and Josie to her flat to inform them of this. When Anna takes Miley to Weatherfield High School to force Faye to take responsibility of her daughter, Jackson tells Greig and Josie the truth, with Josie taking Jackson to the Windasses' to apologise and bond with Miley. When Faye is unable to bond with Miley, Josie and Greig offer for Miley to live with them and Jackson, and when the Hodges later decide to leave for Canada in June 2015, they take Miley with them, devastating the Windasses, except Faye, who believed that Miley would be better off there.

Faye is left stunned in March 2017 when she unexpectedly sees Jackson and Miley in hospital while being treated for an infected tattoo. It transpires that Greig is in need of a special hip transplant, so the Hodges have returned to the UK for him to have the operation. Faye takes Jackson and Miley back home to see her family, however her new boyfriend Seb Franklin (Harry Visinoni) is furious that Jackson has returned. He later savagely beats Jackson up in the street, with Seb being arrested for assault later that night.

Miley Windass, played by Erin, Eilah and Elsie Halliwell, is the daughter of Jackson Hodge (Rhys Cadman) and Faye Windass (Ellie Leach). She made her first screen appearance on 3 April 2015. Triplets Erin, Eilah and Elsie were cast as Miley after the show sent out a call to casting agents and placed posters in maternity units asking for identical twin girls. Their parents got in touch with an agent, and their father explained "We sent some photos over and within two hours we heard back to say they had a client who was interested. On the Monday we were at Coronation Street." Miley returned on 17 March 2017 with her father, Jackson.

Faye discovers she is pregnant in February 2015 and with only the support of her school classmate, Craig Tinker (Colson Smith), she plans to abandon the baby at the hospital once she gives birth. Faye and Craig steal the keys from the shop to Dev Alahan's (Jimmi Harkishin) flat, where Faye goes into labour. Sophie Webster (Brooke Vincent) finds Faye and helps her, before Faye's parents, Anna and Tim Metcalfe (Joe Duttine), arrive. Faye is taken to hospital and gives birth to a daughter. Anna asks Faye if she wants to hold the baby but Faye refuses to hold or look at her. Faye and the baby come home from hospital after Faye is interviewed about the father. It is revealed to be Jackson Hodge, who denies getting Faye pregnant. Anna kicks out Jackson and his family after his mother is cruel about Faye. During a meeting with a social worker, Faye admits that she is not ready to be a mother and thinks that if she gives her baby up, everything will go back to normal, but Owen Armstrong (Ian Puleston-Davies) assures her that giving the baby up is not the best solution. Faye later names her daughter Miley, after the singer Miley Cyrus.

Anna looks after Miley as Faye ignores her baby daughter. Anna later confronts Faye at school, feeling it is time Faye took responsibility and leaves Miley with Faye after embarrassing her in front of her friends, including Miley's father, Jackson. Faye confronts Tim and Anna about her reasons for not being there for Miley, just as Jackson and his mother, Josie, visit. Josie tells her that Jackson has admitted being Miley's father and they are determined to pull together with Tim and Anna to give Miley a good upbringing. Jackson apologizes to Faye for denying that he got her pregnant and Faye forgives him. Tim later suggests getting Miley christened during a discussion with Anna, Faye and Sally Webster (Sally Dynevor). Faye and Jackson go to the registry office to register Miley's birth legally. The teenage parents argue over Faye naming the baby Miley, as Jackson feels that Miley may be bullied at school for being named after a singer. At Miley's christening, Faye breaks down and tells Tim that she is not ready to be a mother. Seeing that Faye is unable to cope with the responsibility, Greig and Josie suggest that Miley go to live with them. Tim come rounds to the idea, thinking that it would be best for everyone, including Faye but Anna is against the idea. When discussing the idea, Faye admits that she could never hate or blame Miley for recent events but loves her daughter and wants what is best for her. In the end, Miley is collected by Josie, as the Windasses share an emotional farewell. Tim admits to Anna and Faye that they, most likely, will not see Miley again, as the Hodges have emigrated to Canada. Tim and Anna discuss it with Faye and Tim says he will get Miley back, but Faye decides Miley will be better off in Canada.

When Faye goes to hospital with an infected tattoo in March 2017, she sees Miley and Jackson. Tim and Anna meet Miley again when Jackson brings her to Faye's house with Faye's brother, Gary Windass (Mikey North) and his ex-girlfriend, Izzy Armstrong (Cherylee Houston). When Jackson is physically assaulted by Faye's boyfriend, Seb Franklin (Harry Visinoni), Josie refuses to let Miley spend time with Faye and her family. However a year later, Faye decide to visit Miley after her adoptive mother was flamed up for Pat Phealan murders. She later mentioned this to her that Josie finally allowed her to see Miley anything she wants. They later decide to spend more time with her after Pat's downfall to death.

Development

On 19 June 2014, it was announced that Faye would fall pregnant at the age of 12, with a show source saying it "is bound to be a controversial storyline but the programme has a history of handling difficult subject matters in a sensitive and considerate way" and that "bosses are still working out the exact details of the controversial storyline, including who the father is." Previously done with Sarah-Louise Platt (Tina O'Brien), producer Stuart Blackburn, said that while "in some respects life went back to normal" for Sarah, "that won't happen" with Faye. Debbie Rush discussed scenes where Faye goes into labour, saying"Obviously none of the family know about it, there's only Craig in on it. As the week unfolds we'll see how he becomes a really good friend" and that "everything explodes." She said that Faye "panics at the end and needs her family" She added that "It's not going to be roses around the door. We're showing just how serious it is" and they hope "that's going to come across. It's not a good thing, and it's really tough on all the family and everyone concerned." Rush described Faye as "an annoying teenager but she came from a really unhappy, broken background - passed from pillar to post."

Following the birth, Faye struggles to bond with Miley, who she names after pop singer Miley Cyrus. Rush explained "Faye doesn’t choose the name for a while [...] because she’s completely in denial." and Faye "calls her Miley, like Wrecking Ball" as Miley "is a wrecking ball!" Jackson Hodge (Rhys Cadman) initially denies being Miley's father, but Jackson and his parents later want to be involved with Miley, however, Anna "realises just how much motherhood is taking its toll" on Faye and she is "forced to consider the possibility of Miley living with the Hodge's." Rush explains "she wants Faye to take responsibility as she thinks that is the best way to get her to bond with the baby" despite Anna knowing "how much Faye has been struggling with the fact that she's now a mum but she's done her best to try and encourage Faye to do the right thing." She added that Anna has "adopted the tough love approach with Faye." Rush says the family are "heartbroken" when it's decided Miley should live with Jackson and his parents, though it's the "right thing for Miley." Faye's pregnancy and Miley's birth acts as a catalyst for the departure of Anna's long-term partner, Owen Armstrong (Ian Puleston-Davies). Owen wrongly assumes Craig is the father and he assaults Craig and Owen's "attitude in the wake of Faye giving birth is the final straw for Anna."

Adrian Mortimer, played by Mark Moraghan, made his first screen appearance on 6 April 2015. The character and casting was announced on 24 February 2015. Moraghan began filming the week before his casting announcement and was contracted for a few months. Adrian departed on 5 June 2015 after two months on the show. Adrian was introduced as a love interest for Eileen Grimshaw (Sue Cleaver). They met when Eileen tried internet dating.

Cathy Matthews, played by Melanie Hill, made her first screen appearance on 20 April 2015. The character and Hill's casting was announced on 23 February 2015. Of her casting, Hill said "I'm chuffed to bits to be joining the cast of my favourite soap. My family and I grew up watching it and to actually be working on it is a dream come true." Cathy was introduced as a potential love interest for Roy Cropper (David Neilson). Cathy owns an allotment and is also getting over the death of her spouse. Series producer Stuart Blackburn described Cathy as "an engaging yet sometimes chaotic woman." He said she had "a heart of gold" and her friendship with Roy would help to "bring out the best in her."

An Inside Soap reporter praised Cathy's introduction, saying "Actress Melanie Hill makes a great first impression as recently bereaved Cathy, but we'll be keeping an eye on how things go between her and Roy. We're still grieving for Hayley (Julie Hesmondhalgh), too!"

Cathy first appears ordering Roy and Sharif Nazir (Marc Anwar) not to ruin her late husband, Alan's, garden patch at the local allotments. Roy is concerned for Cathy as Alan's patch looks very untidy, and attempts to clear it up for her, however Cathy shouts at him and orders him to leave. He returns to the allotments and apologises to Cathy, and they realise they have a mutual connection as they are both widowed. Roy invites Cathy to his café in Weatherfield, however she is reluctant as she is still grieving for Alan. She does so, and is welcomed by the local residents. When it transpires that she has a natural talent in art, Yasmeen Nazir (Shelley King) offers Cathy the opportunity to run her own art classes at the Weatherfield Community Centre. She is at first reluctant due to her shy personality, however she is pleased by the support Roy and the local residents give her.

Roy, Fiz Stape (Jennie McAlpine) and Tyrone Dobbs (Alan Halsall) become suspicious as to why Cathy never invites Roy back to her house or ever mentions her house. Eventually, Roy and Carla Connor (Alison King) go to investigate, and find bailiffs knocking on the door and Cathy shouting at them from a window. The bailiffs leave after being persuaded by Roy and Carla, and Cathy reluctantly lets them in. It is then revealed that Cathy is a hoarder, keeping all of Alan's old belongings and unnecessary items such as ancient newspapers and milk bottles. Roy is adamant that he is going to help Cathy overcome her hoarding, however after he throws out some of the junk, Cathy is overwhelmed with guilt and orders him to leave. She later apologises and bakes him a cake to apologise, however when she tries to reach a book from the bottom of a pile of boxes, the boxes and other large heaps of clutter fall on Cathy, trapping her. Later, Roy arrives and breaks the door down to save Cathy, and after Cathy admits that she is not safe living in her house, Roy insists that she moves into the café flat with him for a while. The next day, Roy treats Cathy to a trip to an art gallery, while Fiz, Tyrone and Chesney Brown (Sam Aston) attempt to clear out some of her clutter. However, when Roy and Cathy return to her house, Cathy breaks down as Fiz, Tyrone and Chesney have completely cleared out all of the clutter, and she orders everybody to leave other than Roy. He eventually manages to show Cathy that the clutter was putting her in danger, but she reveals she cannot move back yet. A few weeks later, she finally decides she can move back into her house, however Roy confides in her that Fiz's young daughter Hope has cancer and that he values Cathy's company during this difficult time, so she remains in Weatherfield for his sake.

Cathy later reveals to Anna Windass (Debbie Rush) that she has developed feelings for Roy, however is worried that telling him will damage their friendship. When Cathy's nephew, Alex Warner (Liam Bairstow) visits the café, he teases Roy and Cathy about how close they are, which upsets and embarrasses Roy. On Roy's birthday in September, Cathy organises a train-themed party at the café for him, however he is upset over Hayley and orders everybody to leave, but Carla assures him that starting a relationship with Cathy would not be betraying Hayley. Cathy then decides to leave Weatherfield after believing Roy will never be able to get over Hayley and start a relationship with her, but her bus breaks down outside the café and Roy admits he has feelings for her too, leading to the pair passionately kissing. Cathy is later frustrated by the arrival of her loud and shameless sister Nessa Warner (Sadie Shimmin), and feels ashamed when she begins a lustful relationship with the recently widowed Ken Barlow (William Roache). On New Year's Day 2016, Cathy decides to clear out the rest of the clutter at her house as a New Year's resolution. When Roy helps her by clearing out Alan's office, he stumbles across some love letters that Alan and Nessa had sent to one another, revealing that they were having an affair behind Cathy's back. Roy is unsure of what to do and confides in Anna, who encourages him to confront Nessa. As Cathy returns to her house to continue with the clear out, she herself comes across the love letters, and when Roy and Nessa arrive, Cathy angrily shouts at Nessa and throws her out before breaking down in tears. Roy then lets slip that he found out about the affair the previous day, and came to the house to help Nessa dispose of the love letters, leading to Cathy throwing Roy out, too.

The following day, Cathy ends her relationship with Roy, stating that he has terminated their mutual trust. She later sets fire to Alan and Nessa's love letters after reading them all, however when she becomes distracted by a phonecall, the fire spreads rapidly. When she witnesses the fire, heaps of clutter fall in the path of the only exit in her haste to reach a sheet in an attempt to calm the flames. Fortunately, Roy and Nessa arrive, and Roy enters the burning house and saves Cathy, who had managed to crawl away from the flames despite suffering from minor smoke inhalation. She is extremely thankful to Roy for saving her, however hostile towards Nessa, after realising how intimate her affair with Alan was. Cathy then returns to live with Roy, and the pair confess their love for one another. While Roy is caring for his mother, Sylvia Goodwin (Stephanie Cole), who has injured her ankle, Cathy allows Alex to move into the café after he falls out with Nessa. In May 2016, Cathy attends Carla and Nick Tilsley's (Ben Price) wedding with Roy upon his return. When she returns to the café after the nuptials are ruined, Alex convinces her that she should propose to Roy, which she does but he declines as Carla is in an unstable state. Upset, she takes Alex to the corner shop, but as they exit, Carla attempts to run over her arch-enemy Tracy Barlow (Kate Ford), but swerves and Cathy is hit by her car as she pushes Alex back into the shop to save him. She is rushed to hospital and told she has concussion and broken ribs, and is devastated when Roy refuses to talk to Carla over the incident, but manages to change his mind before Carla leaves Weatherfield.

After their previous attempt, Roy proposes to Cathy in the café, to which she delightfully accepts. When Alex expresses an interest in purchasing one of Pat Phelan's (Connor McIntyre) flats, Cathy decides to take it upon herself to ask his father, Nigel (Jim Cartwright), for the money for him to do so. However, Nigel is extremely hostile towards Cathy, and after she inquires about his despicable behaviour, he lets slip that somebody ordered him to keep quiet about who has been paying for Alex's maintenance. Confused, Cathy investigates through some old documents, and later confides in Yasmeen that she believes that Alex is the result of her husband, Alan's, affair with her sister, Nessa. Concerned that her theory may be correct, Cathy visits Nigel again, however this time he confirms that Alex is Alan's son, with Cathy taking her frustrations out on Alex. It later transpires that Alex knew all along that Alan was his biological father, and announces that he is going to live with Nessa in Scotland, worrying that he has upset Cathy. The situation eventually takes its toll on Roy and Cathy's relationship, as Roy disagrees with Cathy's treatment of Alex, and he soon comes to the conclusion that the couple need some time apart. On their way to Scotland, the car breaks down and Alex later admits he does not want to live with Nessa and he moves back to Weatherfield. Cathy and Alex make a truce and she reunites with Roy, resuming their relationship.

Cathy continues to gleefully organise her wedding to Roy, unaware that Roy does not love her because he is still in love with Hayley. She is frustrated by the return of Nessa, and is angry when she teases to the residents about Roy sleepwalking into her bedroom. Due to this, Cathy asks Roy whether they should cancel the wedding, and is shattered when Roy believes that it is for the best. She is upset when she finds Roy cancelling the arrangements early in the morning, and that he has informed half of the guests. However, after Roy suffers a panic attack in the Bistro, the wedding is called back on, delighting Cathy while worrying Roy. Worried about remembering her wedding vows, Cathy records them on a dictaphone to help her recite them. Eventually, Tyrone and Brian Packham (Peter Gunn) confront Roy about his feelings, and he admits that he is only marrying Cathy because he promised her when she proposed to him, however the three of them are unaware that Cathy's dictaphone has recorded their conversation. On the day of the wedding, Cathy is joyful and she prepares to marry Roy, but is confused when she hears that Tyrone and Brian have been banned from attending. Upon arriving at the church, she allows Nessa to give her away, and listens to her vows one last time, but she listens to Roy confessing his true feelings instead. She enters the church and calmly confronts Roy, asking the wedding guests to leave. After proposing that they remain close friends, Cathy is crushed by Roy's enthusiasm at the prospect of them breaking up. As a result, Cathy and Alex move out of Roy's flat and in with Yasmeen.

Cathy struggles to move on from her breakup with Roy, however later finds happiness when she enters a relationship with Brian. After securing two jobs at the kebab shop and the corner shop both owned by Dev Alahan (Jimmi Harkishin), Cathy and Brian move into the flat next to the Bistro with Alex. Cathy later suggests to Brian that they look into purchasing a shop to sell antiques. However, this idea eventually fizzles out when Brian decides to return to teaching. Cathy is the first to notice that Brian is being bullied by the deputy headteacher, Phil Gillespie (Tom Turner), when he takes credit for Brian's hardworking ethic. As Phil put more pressure on Brian to achieve, Brian ends up collapsing and suffering a mild heart attack from the stress. Eventually, Cathy joins forces with David Platt (Jack P. Shepherd), Shona Ramsey (Julia Goulding) and Evelyn Plummer (Maureen Lipman) to stand up to Phil for Brian in The Rovers. Cathy later finds herself trying to persuade Chesney to find the courage to ask Gemma Winter (Dolly-Rose Campbell) to be his girlfriend, with her efforts turning out successfully.

Paul was initially contracted for a few months, but his contract could be extended if he proves popular with viewers. Dan is a brewery worker, who catches the eye of Liz McDonald (Beverley Callard).

Dan met Liz in 2014, and, although she almost agreed to a date with him, she later began a relationship with Tony Stewart (Terence Maynard). The following year, after Liz and Tony's relationship ends, Dan invites Liz out for lunch. They later have sex and begin dating. It soon emerges that Dan is a former client of Liz's friend, ex-prostitute, Leanne Battersby (Jane Danson), and that he used to beat her after they had sex. Although Leanne is adamant on informing Liz that Dan is a dangerous man, he later blackmails her, threatening that, if she tells Liz about his past, he will tell her stepson, Simon (Alex Bain), about hers as a prostitute. As time passes by, Leanne, once again, witnesses Dan's violent ways and, unable to stand by and watch Liz get hurt, informs her of what Dan did to her. Liz confronts Dan, in front of his boss and daughter, Lucy (Sammy Oliver), and, despite his efforts to convince everyone that he is innocent, he is fired from his job. Lucy disowns him and Liz throws Dan out of the pub, telling him she never wants to see him again.

The following day, Dan is adamant for revenge on Leanne and Liz and when he spies Leanne leaving work, he follows her home, exclaiming how she and Liz have ruined his life. As Leanne arrives at her flat, Dan forces his way in and throws her to the ground violently. Dan then enters the flat holding Leanne's wrist, and now holds Leanne, Simon and Liz, who was looking after Simon while Leanne was at work, hostage. Liz attempts to talk Dan round by telling him that they could give their relationship another go, but he sees through her antics and when Leanne shouts for help, he violently attacks her and as Liz tries to stop him, she hits her head and collapses. As Liz rises to her feet, Dan reveals the awful truth to a terrified and confused Simon that Leanne used to be a prostitute. Leanne then attacks Dan, allowing Simon and Liz to escape, and they call the police.

Harding explained that Joni knew that Robert was not over Tracy, but it still came as a shock to her. She explained, "Joni is a woman on the edge, and she's very vulnerable.

Harding added that Joni did not want to be second to Tracy and that there would be "fireworks" between them. Harding's first appearance as Joni received a mixed reaction from viewers.

He was initially contracted for one year. Of his casting, Ward said "On hearing the news I had been offered the part on the show, I was in total disbelief. It still hasn't sunk in. Shayne Ward, the lad from Manchester, given such a role on such an iconic show – it is an absolute dream come true. I'm excited to walk down those famous cobbles."

Aidan is a distant cousin of Michelle Connor (Kym Marsh) and grew up on the same estate as Michelle and Carla Connor (Alison King). He is Mancunian-Irish, like Ward, and billed as charismatic, ambitious and "a nice guy". Ward thought it would be fun if Aidan became "a little bit nasty" in the future.

Initial critical reception following Aidan's arrival was mixed; Laura-Jayne Tyler of Inside Soap wondered why Aidan wanted to invest money into a failing Underworld, "Why is Aidan willingly ploughing £40k of savings into a factory that he knows is going bust? Is the poor lad lonely, and just in desperate need of some company?"

On 30 April 2018, it was confirmed that Aidan would commit suicide, with his final scenes airing on 7 May 2018. Coronation Street's writers worked with CALM and the Samaritans when creating the storyline so as to explore the issue of suicide responsibly, and the suicide itself was not shown onscreen. Reception to the treatment of Aidan's suicide and its aftermath was lauded, with fans widely praising the "heartbreaking episode" and Aidan's actor Shayne Ward describing being "overwhelmed" by the reaction. Ward explained how the suicide storyline had helped others in seeking help, with the soap being praised for raising awareness on mental health issues and male suicide.
