Carrie Norton arrived last-minute at Waterloo Road because Havelock High, where her mother wanted her to go, was full. She immediately captured Lenny Brown's affections, although she didn't realise he liked her at first. Lenny's sister Lisa took an immediate dislike to Carrie.
Before it was discovered that Guy and Carrie were brother and sister, Guy nearly got into a lot of trouble when Lenny secretly filmed him hugging Carrie in his classroom.
