For Naya Rivera (Santana), her role on Glee started out as nothing more than a snarky cheerleader. She looked hot, trash talked a bit, and that was all. Little did anyone know that Santana would turn into one of the most unique and influential characters on television.
The bratty Cheerio came out as a lesbian during Glee Season 3, and her emotional journey has given voice to a struggle that many high schoolers face, but few have seen represented on TV. During an interview with Entertainment Tonight, Naya says that she is excited (and a bit overwhelmed) to be given this important role.
