I've binged the whole thing, so I got used to the fluff. The only thing I took from the chapter, was that the kid acts more like a caricature of a kid, than being an actual one.
What sort of a kid goes: "Yaay! Planes! Wow, thank you friend kun! That was really fun!", as if to summarize the experience?
That sort of thing usually flies over my head, it's the sort of thing you get used to. But for some reason, it really stood out this time around.
