Fox revealed that Darren's ex-girlfriend, Cindy Cunningham would become involved in the storyline when Margaret begins trying to "push" Cindy and Darren together. Nancy begins to suspect Darren is having an affair with Cindy which begins because he has "been behaving a bit strangely" while planning the secret wedding. When Cindy helps Darren with planning the wedding they embrace which is witnessed by Nancy which "confirms everything that she thought. To Nancy, it seems that everything her mum is saying is true - that Darren doesn't love her and he has been having an affair". Her portrayer explained that she would have expected Nancy to confront Cindy but Nancy can not "bring herself to do it. [...] you see that this relationship has meant more to Nancy than any other. She's deeply, deeply hurt". Dawson explained that the storyline is "just a case of Nancy getting things misconstrued" and that it is not a "obvious affair plot".
