Rose Tyler has met Lee Ashworth while working as a trainee hairdresser for Claire Ripley in Sandbrook. Things start to get complicated when they move to a rented house and a young girl dies while her older cousin goes missing. Alec Hardy is in charge of the case and thinks Rose knows more than she says and offers her protection by moving her to Broadchurch after starting an affair with her.
Rose Tyler arrives in Sandbrook when she hears 2 cousins have gone missing. She and Alec Hardy don't get on and he has a row with his wife when he sees her cheating on him and tries to book in at the same hotel but they don't have any rooms. He asks if Rose is staying there and knocks on her door. Rose then has to work with Tess without giving the game away.
Rose Tyler met Alec Hardy the first day she went to a new school when she was just 13. Her mother had followed a boyfriend to Paisley in Scotland and said they were staying. Rose dare not speak at first but Alec was different. He became her friend, they had their first kiss at 13 but 3 years later, she was gone. This is how they found each other and fell in love again in 2012.
