is later revealed that this is because Cindy knew that Peter's friend from Devon had died whilst swimming, and Peter suffered from survivor's guilt as a result. David returned to Walford in September that year, hoping to reunite with Carol despite her relationship with Masood Ahmed. Eventually, the former couple reconciled but Carol ended her relationship with David on their wedding day when she realised that he still had trouble with commitment, with David subsequently moving to Florida. In 2014, Jane Beale returns to Walford and becomes a partner in Ian's new restaurant. Lucy also opens her own lettings agency, called LB Lettings, with her best friend Lauren Branning. However, Lucy is having a fling with Lauren's father, Max Branning. Cindy Williams also has sex with TJ Spraggan, in spite of having a relationship with Ian's great nephew Liam Butcher, and gets pregnant by him. Peter begins a relationship with Lola Pearce and moves in with her. Lucy calls off her relationship with Max and it is revealed that she is using cocaine on a regular basis because of problems with her father. After beginning a relationship with Lee Carter, tensions arise between her and Whitney as she is also interested in Lee. Although Whitney and Lee begin a relationship, Lucy's dead body is found on Walford Common (see Who Killed Lucy Beale?); when Ian hears the news, he is devastated. Jane leaves Walford with Bobby to overcome their grief away from Ian. Peter moves back in with Ian when his relationship with Lola hits a rough patch. DC Emma Summerhayes becomes the Beales' family liaison officer following Lucy's death, and, at Lucy's funeral, her relationship with Max is revealed, causing Ian to lash out at him publicly. Denise nearly leaves Ian, but decides to stay and they grow closer. Phil begins to question Ian's alibi when he overhears Cindy questioning Ian as she knows his alibi is fake, and later it is revealed Ian saw prostitute Rainie Cross on the night Lucy died. Rainie begins blackmailing Ian, threatening to reveal his infidelity to Denise in order to fund her drug habit. When Ian stops paying her, she reveals what happened to Patrick Trueman, Denise's father figure. Patrick tries to tell Denise but suffers a stroke before he can. Various suspects, including Max, Jake Stone, and Billy Mitchell, are questioned by the police, but they are all proved innocent. DI
