When Sarah's mother,
Debbie Dingle (
Charley Webb), discovers she is pregnant at age fifteen, she conceals it and plans to leave the baby at the hospital after birth. Sarah is born in a shed with help from
Daz Eden (
Luke Tittensor) and is named Sarah Charity after her grandmothers
Sarah Sugden (
Alyson Spiro) and
Charity Dingle (
Emma Atkins). Debbie decides that she cannot raise a daughter and persuades
Emily Kirk (
Kate McGregor) to take Sarah when she leaves the village. Emily returns Sarah after
Ethan Blake (
Liam O'Brien) convinces her that Sarah should live with her father,
Andy Sugden (
Kelvin Fletcher). Debbie's step-grandmother,
Lisa Dingle (
Jane Cox), tries to get Debbie to bond with Sarah, but she refuses and suggests that Andy's ex-girlfriend,
Jo Stiles (
Roxanne Pallett), adopts Sarah; however, she does not sign the papers. When Andy goes to prison, Sarah and Debbie start to bond. Upon his release, he starts abusing Jo and at nursery, Sarah bites another child, resulting in her suspension. Andy moves out, leaving Sarah in Jo's care but is permitted supervised access. When Jo leaves the villages, Sarah is reluctantly left with Debbie's family. Sarah and Debbie become closer, but she refuses to take custody. Sarah spends a night at Andy's house following the funeral of his father,
Jack Sugden (
Clive Hornby). Debbie and Andy fight for custody of Sarah, which is awarded to Debbie after Andy withdraws his application. Sarah begins to bruise and tire easily, worrying her parents, who believe someone is hurting her. After consulting a doctor, Sarah is diagnosed with
Fanconi anemia (FA), which develops into
leukemia. Sarah needs a
bone marrow transplant and when a donor withdraws, her parents consider a
saviour sibling. After being refused IVF, Debbie and Andy decide to conceive naturally, with the agreement of their partners. Sarah's brother,
Jack Sugden (Seth Ball), is born and is a match for Sarah to have the transplant. A year later, Sarah is taken hostage by Debbie's serial killer ex-boyfriend,
Cameron Murray (
Dominic Power), but is saved by Andy and
Moira Barton (
Natalie J. Robb). Over two years later, Sarah leaves the village with Debbie and Jack. A year later, Sarah, Debbie and Jack return to the village in a stolen car. Sarah and Jack are taken hostage by Debbie's bosses until she raises £50,000. Debbie reveals that Sarah has
throat cancer and a fundraising page is set up to fund her
proton beam therapy; an anonymous donation of £20,000 is made. Sarah finds a poorly
Faith Dingle (
Sally Dexter) in a barn, unaware she is Debbie's paternal grandmother. Faith collapses at the B&B and reveals that she made the donation. Sarah has treatment and recovers. Over a year later, she collapses with heart failure as a rare result of her chemotherapy. A matching heart is found but then discovered to be unfit. Emotionally and physically exhausted, Sarah questions whether a new heart would be worth the pain and hassle, and consequently refuses the transplant. After weeks of persuasion, she agrees to the transplant, which is successful. When Debbie moves to Scotland, Sarah asks to stay with Charity and her partner
Vanessa Woodfield (
Michelle Hardwick), which Debbie agrees to. Sarah begins talking to
Danny Harrington (Louis Healy) online and they meet when Sarah play truant. Charity and Vanessa warn Danny away, so Sarah explains that she meets him because she wants to enjoy herself in case she dies young from her illness. They agree to Sarah seeing Danny, but at a party, he gives her drugs. He convinces Sarah to sell drugs for him and claims that he will be beaten if he does not deliver, showing her injuries on his body. After learning the injury was from falling off his bike, Sarah realises that she was used and plants drugs in his pocket, before reporting him to the police. Danny is arrested and serves a jail sentence for at least a year in a youth detention facility; upon his release, he tries to rekindle their relationship but shows that he wants to use Sarah again for more drug transport instead of love. ==Reception==
