Sinead Osbourne (also
Tinker ), played by
Katie McGlynn, made her first screen appearance on 19 April 2013. The character and casting was announced on 22 February 2013. Sinead is the niece of established character
Beth Tinker (
Lisa George). She died on 25 October 2019. Sinead's aunt, Beth, contacts her and asks her to come to Coronation Street for a visit. Beth tries to set Sinead up with Chesney, who has recently broken up with his girlfriend,
Katy Armstrong (
Georgia May Foote). The pair really hit it off and Sinead agrees to go on another date with Chesney, but when Katy and her lover
Ryan Connor (
Sol Heras) arrive, Sinead feels that Chesney is using her to get back at Katy. When Katy moves in with Ryan and his family, Chesney acts like he could not care less, but Sinead can see that he is hurt by Katy's actions. Sinead sees through Chesney and realises that he is using her to get back at Katy, which infuriates her. After a talk with her aunt Beth, Sinead understands that she can't let Chesney use her. When Katy and Ryan ask Chesney and Sinead to look after Katy and Chesney's baby son,
Joseph, Chesney tells them that they are going out for the night so they can't. But when the couple return home, Chesney reveals that they are not going out, which angers Sinead. They eventually do, with Beth and Kirk, but leave early as Sinead realises that Chesney does not want to be out. She argues with Chesney in the street, and later clashes with Katy, after she tries to give her boyfriend advice. During a date night, Sinead suggests to Chesney that they have sex, but Chesney turns her down. When Chesney reveals that he does not love her, Sinead says she understands. She stays overnight in Chesney's bed, while he sleeps on the sofa. Unhappy with the relationship, Sinead ends it and leaves. When Katy begs Chesney for another chance, Chesney rejects her and calls Sinead. She asks Chesney not to mess her about and they reunite. Sinead is very supportive when Chesney is told that his foster carer
Hayley Cropper (
Julie Hesmondhalgh) is dying from incurable
pancreatic cancer. Sinead also attends Hayley's husband,
Roy's (
David Neilson), birthday party with Chesney. Sinead gets a job working at Underworld after helping Beth to win an Employee of the Month competition. It was announced on 30 October 2014 that
Coronation Street would air a mini-bus crash, involving the members of
Underworld – including Sinead, after
Steve McDonald (
Simon Gregson) crashes the bus. A show spokesperson commented: "Exact details are being kept under wraps, but more than one character will be hospitalised as a result of the crash and one Underworld knicker stitcher's life will be on the line! Locations for the smash are currently being explored to find a suitably dramatic setting for what promises to be a high octane start to 2015 for Corrie fans." The scenes were filmed on 19 November 2014. The show released more information on the crash aftermath in January 2015. It was revealed that Sinead would be left worst from the crash, with "devastating" effects for her and Chesney. Producer, Stuart Blackburn, said that Sinead would be injured very seriously and that they would be "heartbreaking" scenes airing, "I have been watching some early scenes that have been shot of Katie McGlynn, who plays Sinead, and Sam Aston, who plays Chesney. It is just truly, truly heartbreaking. They have a long way to go. We all know how forgiving Sinead is, but I don't think Chesney is ever going to stop blaming Steve for that." McGlynn later spoke to
Digital Spy, revealing Sinead's recovery is a long process and that she will be left wondering if she will walk again. It was revealed on 6 January 2015 that former
Hollyoaks star, Peter Mitchell, would be starring in
Coronation Street as a character that one established character – revealed to be Sinead – would meet after the bus crash. Mitchell is disabled and it was thought Sinead would be involved with him after she is made paralysed. Mitchell later spoke to
Digital Spy about his new role as patient Sam, who would become friends with Sinead, revealing that he would become an "ally" for Sinead when she is left paralysed. He also praised McGlynn and Aston and commented that they are "brilliant" to work alongside. Sinead's storyline played out onscreen from January until April 2015, with her back to her previous self by May. In 2016, Sinead starts modelling which is met with criticism by Chesney. In January 2017, Sinead grows bored of Chesney and begins sleeping with
Daniel Osbourne (
Rob Mallard). Chesney finds out and breaks up with her leading to her moving in with Daniel. After finding out she is pregnant Daniel turns down his
Oxford university application causing Daniel's father
Ken Barlow's (
William Roache) to turn on Sinead which prompts her to have a secret abortion. Due to this Sinead was a major suspect (which was later revealed to be Daniel) in the "Who Attacked Ken?" storyline. Daniel later finds out about this and they split up with Sinead later getting back with Chesney who she becomes engaged to; however, they split on their wedding day after Chesney tells Sinead he does not love her and that he feels like he is just marrying her for a mother for his son Joseph, who returned in October after his real mother, Katy, died in a car accident. Sinead visits Daniel's flat in just lingerie and they have sex, getting back together again. She later gets pregnant and gets engaged to Daniel. However, she starts bleeding, goes for a baby scan and is told she may have
cervical cancer, which she does not tell Daniel about. Daniel arranges for them to have a pagan wedding with Kirk officiating. Sinead is then diagnosed with an aggressive form of cervical cancer and is told she will have to terminate her pregnancy if she wants to have radiotherapy. After being told this Sinead says she doesn't want radiotherapy as she wants to keep her baby and breaks down in hospital. She confides in Ken about the cancer after he sees her in hospital. Sinead eventually tells Daniel about her cancer diagnosis, but she remains adamant that she does not wish to receive treatment until the baby is born. Sinead eventually gives birth to a boy called
Bertie, to which Sinead finally begins treatment for her cancer. The treatment works and the cancer goes into remission. Happy to have a new lease on life, Sinead decides she wants to leave the Street and live somewhere new with Daniel and Bertie. They agree to do this when an opportunity arises, and they decide to have a larger wedding reception to make up for the smaller one that was postponed. During the reception, Sinead discovers another lump, and upon returning to the hospital, she learns the cancer has recurred and is now terminal, with Sinead being given a months, if not weeks, left to live. Although devastated, Sinead decides to settle loose ends, such as reconnecting with family she lost contact with, and ensuring with Carla that the money Underworld made using Sinead's formula of beard oils is placed into a trust fund for Bertie for when he is older. In the following weeks, Sinead's health deteriorates, with family and friends visiting her on her deathbed in home to say their last goodbyes. When alone with Daniel, she tells him not to spend the rest of his life mourning her and says he will always have her blessing for whatever relationship he may enter once she is gone. When Daniel goes to put Bertie to bed, he returns to discover Sinead has peacefully died in her sleep. Her funeral takes place the following weeks, with many in the Street attending or paying their respects. In May 2017, Laura-Jayne Tyler from
Inside Soap called Sinead's relationship with Chesney a "snore-fest" and asked
Coronation Street to "put us out of our misery" and end their relationship "for the love of all that is good in this world". ==Jake Windass==
