I used to think Klavier was pretty boring, and I get it, instead of redoing another character's arc he starts at the end of someone else's - prioritizing the truth and being a friendly cooperative rival, so he doesn't really undergo a lot of change it seems, he's sort of reacting to other characters' changes, but eh! He sorta faces some music at the end of 4 after running from it, it's neat enough! And the way he shows up in 5 and one of the non-canon DLC in 6 feels really... I dunno, like yeah, he doesn't have what it takes to be the big return in some final case or anything. But I dunno!!! Nah, he's cool! He's not at the top of my list, but nah, he's plenty cool and fun, if we wanna talk boring then it's gatta go to Nahyuta - I like his design and music and everything but damn he makes me snooze!
