Holly Holliday is a substitute teacher at McKinley High, and she actually makes the classroom fun. (A fun substitute teacher? We thought those didn’t exist, sort of like a good Vin Diesel movie.) She covers for glee club when Mr. Schue (Matthew Morrison) is out sick, and the New Directions members love that she’s willing to listen to their ideas for song selections. Plus, she’s got a dynamite voice of her own, as she demonstrates in her bang-up cover of “Forget You.” Who knew a cover could actually do the Cee-Lo original justice? (Plus, the girl’s got legs that won’t quit. Just sayin’.)
When Holly returns later in Season 2 as the new sex-ed teacher, things really start to heat up — especially between her and Schue. They kiss, and she claims she’s too unstable for Will — but they decide to give it a shot anyway, because when does Schue listen to common sense when it comes to his love life? Holly also encourages the students to learn more about their bodies and be in touch with their feelings. No wonder McKinley High’s prude parents send her packing!
