 Fox said that Nancy has a bit of a "bad girl" in her which she shows during her confrontations with Mercedes, adding that the character has got "more fire in her belly than maybe we'd realised".Nancy does not tell Darren that she is helping Mitzeee, which Fox told a reporter from "What's on TV" is because "Darren is so focused on the baby that if she told him he'd be really angry.Nancy feels he doesn't understand the relationship she has with Mitzeee and he hasn't been terribly supportive".
