Gotta say I not really a fan of the random speaker system for festivals. In Albero Verde you got to check in with everyone and they had unique path and hyper dialogue. Now I only see three candidates and I don't get a report on my character or Emily at festivals. Of course nobody has hyper dialogue yet but it still feels like a real downgrade from Albero Verde. The random speaker doesn't make them more unique just faster to skip.
Thinking on it more if you want festivals to feel more unique then you still have everyone but have random dialogue for each image variant (normal/hyper/path variants). So it is not always the same dialogue each time but people still get to see their favorites. Of course if you really want to go above and beyond with this have multiple possible images for each different tier. it would do wonders for making each festival feel unique.
