Donna catches them in bed together the next day and Kelly implies that they have slept together but admits they didn't when Donna threatens to tell Viv. She causes trouble for Dawn when she flirts with Scott, gets him drunk and drags him into her bed, secretly phoning Dawn and she hears them talking. Throwing herself into village life, she makes enemies of Zoe Tate and Dawn Woods - both ex-girlfriends of Scott. Kelly returns in 2005 and it was clear that she had not changed. With no friends or family willing to talk to her, Kelly leaves for London, with only her younger sister, Donna, sad to see her go. Feeling rejected again, Kelly tries seducing Viv's new fiance, Bob Hope, but he tells Viv and this leads to a vicious fight between Viv and Kelly, also revealing Scott and Kelly's affair. Although she and Roy have a brief reconciliation, they are unable to make their marriage work and he leaves for Ibiza without her. Scott burns the letters but Kelly confesses to Roy and decides to start a new life in London, bankrolled by Chris Tate. She is saved but loses the baby she was carrying, unsure if the father was Scott or Roy. After writing letters to her family and admitting to the affair on tape, Kelly attempts suicide. Whilst he is away, Kelly sleeps with Scott again after meeting him at a hotel and they admit their love for each other, sending Kelly into a deep depression. Wanting to protect Kelly, Roy accepts responsibility and is imprisoned. When Kelly "borrows" jewellery from a client, Miss Curtis, and stages a dinner party at her house, the police are called. After they get married, Kelly and Roy have financial problems and become cleaners. Whilst planning their wedding, Kelly continues to see Scott but refuses to leave Roy so Scott exposes their affair but Kelly denies it. After sleeping together, Kelly returns to Roy and they get engaged. In 1998, Kelly realises that she has romantic feelings for her stepbrother, Scott. She threatens to press charges but eventually accepts £1,000 from Steve Marchant as compensation. Kelly secretly plans an abortion but miscarries after a fight with Kim Tate leads her to fall down a flight of stairs. Due to the side-effects of his disability, he is scared about the possibility of not being able to have children and asks Kelly to keep the baby. Discovering she is pregnant by Biff, Kelly tells Chris Tate that he is the father, hoping he would pay for an abortion. She toys with Roy's affections, has a one-night stand with Biff Fowler and a brief fling with Will Cairns. Having been betrayed, she stops trusting men and behaves promiscuously. The couple decide to run away together but Kelly returns a few months later, telling Viv that she left Tom after finding him in bed with another pupil. When their affair is exposed, Kelly denies it but no one believes them and Tom loses his job. Kelly's next relationship is with her teacher, Tom Bainbridge. They date briefly but being teenagers, soon split up. Kelly's first boyfriend is local teenager, Roy Glover.

Just a couple of weeks later, a plane crashed on the village, and a fireball almost killed Kelly and her siblings but they survived as they ducked for safety. In December that year Kelly became a teenager. Kelly arrives in Beckindale in August 1993 with her father Vic, stepmother Viv, stepbrother Scott and half-sister, Donna. Kelly gained a stepbrother, Scott, Viv's son from her first marriage, and a half-sister, Donna, from Vic and Viv's marriage. As Kelly did not know this, she loved Viv like a mother. Horrified, she ran outside and was hit by a car as she was too upset to look where she was going. Kelly, for a long time, didn't know that Anne had died after catching Vic in bed with Viv Dawson.

Kelly is the daughter of Vic and Anne Windsor.
