So good. I think that weirdly, Leon's speech caused the most commotion until now for obvious reasons, but I'm sure it had an opposite effect on many others students than cheers just like with Kohitsuji. It's more than time to realize that they've actually known some students from the other dormitories for 10 years, and what's make some of the charm of this academy is this chaotic mixing. They're genuinely having fun, always fighting, competing with each other and getting better and stronger in the process.
Inuzuka's speech was then the perfect wake-up call. Leon appealed to their shared hatred and negative feelings about the academy, while he put everything including her and their bigoted ways, and showed them that there's hope for many positive changes if they can dare to challenge the status quo. His socratic exchange by allowing the audience to speak freely and answer his questions was the cherry on top.
