Smear sideways to said English class. There's a band, and three backup singers clustered around an old-timey microphone. And then we see Holly, singing "Conjunction Junction." Out in the audience... I mean, "class," Kurt is sitting next to some long-haired stoner in an army surplus jacket who asks him if he's on anything, because apparently being high would make you appreciate Ms. Holliday's performance that much more. Kurt: "You smell homeless, Brett. Homeless." Before we smear back to the present, two quick observations. First, if these kids are just learning about conjunctions in high school, the Lima public schools are in worse shape than we ever imagined. Second, I assume that Holly brought those backup singers to school with her. Because if they were students, someone should have recruited them to join the Glee Club a long time ago. And really, hiring your own backup singers shows remarkable dedication to being a substitute teacher.
In the present, Holly Holliday accepts Kurt's offer to take over the Glee Club. If I were them, I probably would have consulted Principal Sue before making that official. Of course, if I were them, this entire scene would be taking place in a law firm and it would be a lot less fun. Also, if I were them, I'd apparently have multiple personality disorder. So, all-in-all, it's probably good that I'm not them.
