Crace observed that Danielle was intrigued by Ronnie and the Mitchells, but also worried that she was too different from them and might be a disappointment to Ronnie. Danielle became pregnant, which was used as a plot-device to bring the two closer together, with Ronnie supporting her when she chose to have an abortion. The writers deliberately played on the tragedy of Ronnie being unaware that she was encouraging the abortion of her own grandchild. Ronnie failed to attend Danielle's second clinic appointment, which Crace stated left her character "hurt and distraught" and less willing to confide the truth in Ronnie than ever. On Ronnie's part, Womack assessed that her character was unaware why she had bonded with Danielle. She deemed her totally unaware of any physical resemblance between herself and Danielle, and stated that she had never entertained the notion that Danielle might be her daughter. In the aftermath of her abortion, Danielle was depicted as being increasingly emotionally unstable and angry with Ronnie, believing that she deserved to belong to the Mitchell family. The writers had Archie discover her secret as a test of his character, experimenting with whether he would be despicable enough to conceal the truth. Lamb deemed Danielle "a huge threat" to Archie's position as patriarch of the Mitchell family. As such, Archie lied that Ronnie was suffering from depression and convinced Danielle not to reveal the truth for the sake of her mother's mental well-being. Danielle accepted the lie, believing it to explain Ronnie's "hot and cold" reaction to her, and attempted to care for Ronnie and help her recover. Crace explained that despite their turbulent relationship, Ronnie was all Danielle had ever wanted. The ultimate revelation of Danielle's identity was set at Archie's wedding to Peggy. Santer explained: "Weddings are great because they bring the community together. A wedding gives you a stage, it gives you an event, the context to play things out, so it felt right that these big Mitchell stories would collide at Peggy's wedding." Writer James Payne concurred that setting the reveal at the wedding helped to make the moment "as dramatic and sensational" as it could possibly be. In the episode, Danielle announces that she is Ronnie's daughter in front of the entire wedding reception party. She is met with disbelief, and thrown out by Ronnie. Soon thereafter, however, Ronnie discovers that Danielle has an identical locket to her own. Having given the matching locket to her daughter, Ronnie realises that Danielle was telling the truth. She hurries to find her, but just as they are about to be reunited, Danielle is run down by local resident Janine Butcher (Charlie Brooks), and subsequently dies in Ronnie's arms.
