This role is actually three separate "extras" from both movies that don't really have a face and only have one or two lines. This both fills in multiple extras as well as gives whoever wants the part more than just 5 seconds in the films. The first line is a student chatting with his friend about scouts coming to watch their races, the second is a teammate cheering another on, and the third is a teammate exclaiming how amazing an upperclassman is.
