In September 2009, it was revealed that Danson had recently returned to work with the show. Danson admitted that was "terrified" about returning, saying "I felt like I’d been in Babyworld for ages and I was panicking about whether I could learn my lines. There didn’t seem to be enough hours in the day with two kids, but you somehow find the time." Leanne made her full-time return on 11 September 2009 when Peter finds her in Leeds. Danson said that Leanne is getting on with her life and tells Peter that she has moved on from their relationship. However, Leanne "has a change of heart and comes back Weatherfield". She tells Janice that she has split up with her boyfriend and Peter invites her for dinner. Peter admits to a "few meaningless flings" and Leanne spends the night with him. However, Leanne becomes suspicious about remark that Simon makes about Michelle Connor (Kym Marsh). Leanne tricks Michelle, who reveals her one-night stand with Peter. Leanne then refuses to reconcile with him. When Peter apologises to Leanne, she throws eggs at him and refuses to forgive him. Leanne and Peter later reconcile. Leanne and Peter's relationship hits rock bottom. Leanne proposes to Peter. In an interview with "What's on TV", Danson said that Peter and Leanne make a good couple and expressed her desire for the couple to marry at some point. After Peter accepts Leanne's proposal, asked if Leanne wants to be a real mum to Simon, Danson said: "She'd like to. Her mum left when she was little and Janice came to her rescue. Leanne wants to be as good at being a mum and she is. All she's ever wanted is the family set-up she has with Peter and Simon."
