Naomi arrives in Albert Square as Sonia Fowler's nurse friend. She lives with Dot Branning and Jim Branning, then moves in with Garry Hobbs and Minty Peterson. Garry takes a liking to Naomi and they share a kiss, but she develops romantic feelings for Sonia. Sonia tells Naomi that she is having problems with her husband Martin Fowler and is considering a trial separation. Naomi consoles Sonia and they kiss, but Sonia immediately regrets it. Martin blames Naomi for spoiling his marriage, and they become enemies. Naomi initially accepts that Sonia still loves Martin and remains friends with her. However, Sonia eventually leaves Martin to live with Naomi.
After a while, Sonia and Naomi argue about Sonia and Martin's ongoing battle to become their biological daughter Rebecca Fowler's legal guardians in case of her adopted grandmother Margaret Wilson's death. Sonia prioritises Rebecca over Naomi, so Naomi throws Sonia out and they split up. Naomi joins Dr. May Wright working at Albert Square's surgery, and plans to buy a house with Garry and Minty. She is accepted for a job at the local children's hospital. When she discovers that May is taking pills prescribed to Manju Patel, Naomi agrees to keep quiet but May does not believe her so plants the pills on Naomi and blames her for taking them. May tells Naomi if she does not leave Walford she will make a phone call to ruin the career for which she has been preparing for three years. Naomi pulls out of the sale of the flat and leaves even though Garry, Minty and Dawn Swann try to get her to bring May down.
