Dotty was used as Nick's partner in crime, as the duo planned to kill her grandmother Dot and inherit the money from her will. She and Dot subsequently became friends after Nick's failed murder attempt, due to Dotty sabotaging their murder plan at the last minute.
Dotty was the result of sex that Nick had with an alcoholic woman named Sandy. Whilst serving time in prison, Nick received a letter from Sandy telling him that she had given birth to their daughter. Upon his early release from prison in April 2008, Nick took custody of Dotty, having told her that Sandy had died in a car crash. On the 16 February 2010, Dotty's mum arrives, showing she is not dead.
Dotty arrives in Walford Boxing Day 2008 with her father Nick, to see his estranged mother Dot Branning. Nick introduces Dot to Dotty and they quickly bond. He lies to Dot that he had promised to send money to Sandy on the condition that she named their daughter Dorothy after her grandmother, so that Dot will trust him and bond with his daughter; Dot does not know Dotty's real name. After spending the night, Dotty begs Dot to let them stay longer. Dot lets them stay for the rest of the week. Dot soon discovers that Nick hasn't changed; he doesn't have a job and he and Dotty have been living rough. Nick says he will either put Dotty into care, or sell her to Dot for the money that Bradley Branning had given her. After serious consideration, she buys Dotty, to get her away from Nick.
Dotty learns that Dot has made a will, leaving all of her money to Dotty when she dies. She tells Nick, and they form a plan to kill Dot in order to inherit the money. They trick her into thinking she is suffering from dementia. Eventually, Nick tells Dotty to give Dot an overdose of her medication by crushing up the tablets and putting them in her tea. However, Dotty has had a change of heart, and gives the pills to Nick in his beer. When Nick learns of Dotty's double-crossing, He drags her to the café and holds everyone inside hostage. Dotty manages to escape along with most of the others, but the café explodes, and in the commotion, Nick escapes. Later, Dot suspects her granddaughter may be just as evil as her father, So she plants some tablets on the kitchen table whilst Dotty has her back turned. Dot leaves the room, and then spies Dotty ignoring the tablets and pinching a chocolate biscuit instead. While practising for the nativity, Dotty causes trouble by being naughty, But vows to be good when 'Father Christmas' takes a visit to the community centre.
Dotty holds a birthday party for Dot, inviting Tiffany Dean and Liam Butcher, but they do not want to go. Dot tells Dotty that a lot of people cancelled. When Dotty looks out of the window, she waves at Tiffany, who pokes out her tongue. The next day, Tiffany tells Dotty she is not invited to her birthday party. Dotty tells Dot that Tiffany is not having a party and asks if they can invite her round. When they ask Tiffany's mother Bianca Jackson, Carol invites them to Tiffany's party. The next day, Tiffany and Dotty lie so they do not have to go to school. Dotty takes Tiffany's bridesmaid's dress and MP3 player and runs away with them, throwing the MP3 player into a bin in the Square. Tiffany tries to get it and then Dotty pushes her in. When Max Branning sees her, saying she should be in school, she runs away. When Bianca realises Tiffany's dress is missing, Jack says he saw Dotty with something by the bins. Tiffany will not say how she got in the bins, so Carol goes to see Dot, who says it is not like Dotty, who is a kind and gentle girl. Dotty tells Dot she knows nothing about the dress but Dot then finds it in Dotty's school bag. Dot returns the dress to Bianca without Dotty's knowledge. The next day, Dotty is left alone with Dot's husband Jim Branning who is recovering from a stroke. She pours water on him to make it seem he has wet himself, but Dot catches her. Dotty says she hates them both and wishes that Nick had killed her. Dot then very hardly smacks Dotty's bottom, making her squeal just as Jim's granddaughter Sonia Fowler, who is visiting, walks in. Dot apologises, but Dotty manipulates her into letting her stay off school. After Dotty calls the police, Dot is arrested for assault and Sonia tells Dotty off for making it seem like she was an abused child. However, Dot is released without charge but is told to expect a visit from Child Care. When Dot senior returns home, Dotty apologises.
Dot receives a visit from Dotty's mother Sandy, who Dot assumes is from Social Services, but she is looking for her daughter Kirsty. Dot says she knows nobody of that name but realises it is Dotty when she sees a photo. Dot hides Sandy's visit from Dotty but later talks to Sandy about Dotty and her past. When she goes home, she asks Dotty about friends and family she used to have, but Dotty says Dot is the only family she needs. However, Dotty soon admits that she misses her mother, and Dot reveals that she is alive and Nick had lied to her. Dotty says she wants to see her mother, so Dot calls her. When her mother Sandy arrives, Dotty is delighted and Dot tells Dotty she should go with her mother. They say an emotional goodbye, and Dot says she can visit at any time.
Dotty returned with Dot in October 2019.
