Lucy aspires to be a fashion designer, and along the books already makes some clothes for her and her friends. She also likes to make jokes, and has two older brothers, Steve and Lal. Lucy dates Nesta's brother, Tony, on and off throughout the series, but is also seeing others throughout the course of the books.
