Last night’s Glee involved a Carrie-inspired prom scene (red Slushie instead of pig’s blood), Demi Lovato’s first appearance as a sapphic love interest, and the gang in full Sergeant Pepper’s Lonely Hearts Club attire. Not only that, but Naya Rivera’s Santana got what just might be her big break, appearing in a hilarious yeast infection commercial. Perhaps a slight reference to Rivera’s own adorable (if disturbingly cannibalistic) M&M’s ads?
