Kabru is without doubt a manipulative and sanctimonious psychopath. It is deeply troubling that he and several members of his party believe that he's the right person to conquer the dungeon and rule the island. That episode was a great example of Show Don't Tell because we got a full course of the type of person he is.
That he's such a good judge of character is further proof that he's a psychopath, imo.
...Meanwhile, Shuro immediately quit the party and gathered his entire harem to rescue his crush, Falin. haha. The better part of the Shuro developments is that everyone in Laios' party already knew that Shuro had a ridiculously strong crush on Falin and just like...ignored it. Poor guy.
I continue to love the contrast between Laios' party and any others. Kabru and team thinks they're hot shit but Kabru doesn't know monster anatomy. They've died multiple times to monsters, but they're really good at killing humanoids. They're smart and make good plans and they fall apart when it counts. Others like the gnome couple are overly cautious and retreat frequently to keep themselves safe, though he abuses Namari as a meat shield or bait. Shuro's team has astonishingly good teamwork and fierce loyalty to their apparently high-ranking leader (and now we gotta wonder why he was with Laios' party solo to begin with). Then you have the Liaos party, who are all morons, but remarkably successful and resilient. They each have a specialty and trust each other with those skills.
And lastly, Senshi having no clue how old anyone is, is the funniest gag of episode 15. Senshi thinks Chilchuck is a child, but Mick's dialogue tells us Chilchuck has been around the island for quite a while and is one of the most influential members of the half-foot community.
This is how you do fantasy races interacting properly. Misalignment of perspectives!
