Will, obviously trying to get back in Emma's good graces, suggests Hot Carl speak with the Glee Club that afternoon. "I'm usually pretty tight about our rehearsal schedule," Will goes to great lengths to explain, "but I think I can loosen the reins a little bit for [Hot] Carl!" Shut up, Will. Unfortunately, Loosening The Reins A Little Bit In Order To Impress Emma will be his character's throughline for the rest of the evening, so he'll never shut up about it, ever. Oy.

Meanwhile, out in the hall, those meathead bruiser assholes whose names I never bothered to learn are harassing Finn again, this time by confiscating his letterman's jacket and ripping it in two right there in front of all their gawking classmates. Finn tries to deck one of them, but ends up slamming his fist into a locker, so the meathead bruiser assholes harass him some more until Artie wheels over to apologize to Finn for getting him kicked off the football team. The meatheads ramble on for a bit about their nonexistent moral codes before leaving, but none of that is important at the moment, because what is important is the fact that Coach Beiste has been sternly eavesdropping on the entire altercation. She gets an idea, nods briefly to herself, then exits the frame so we might zip over to...

Emma brightly interrupts from the sidelines, where she's standing next to Will. "Let's stay focused!" There follows some unimportant banter between Hot Carl and Mr. Schue that only serves to reinforce how unthreatened Hot Carl appears to be by his girlfriend's ex, and then the children chew on Hot Carl's magical tablets. Surprisingly enough, the only three to come out at the other end of the experience with soiled mouths are Rachel, even though she flosses between classes, Artie, who guesses he'd take better care of his teeth if he could actually see himself in the mirror, and Brittany, who rinses her mouth out with soda after she eats, because she was under the impression that Dr. Pepper was a dentist. Appointments are quickly scheduled for each of the foulmouthed teens, and the next thing we know...
