The thing I don't like about Joseph in part 4 - and I know this is a Japanese trope in anime and manga, but still - is that all of a sudden he starts using these "old people" words, like "ja" instead of "da" or "ja no" instead of "da ne".
I get it, he's old, not to mention senile, but after hearing him actually speak like a normal person for 2 arcs, the sudden switch to "old people talk" is really jarring to me. Characters in anime and manga tend to be young or old, but they rarely age enough during the course of the story to go from young to 70+, so it's usually not an issue, but in this case I feel they/Araki should have broken the rule.
. It wouldn't be weird if Joseph was always known as an old dude from the get-go, as that's the way old people speak in most anime, but it's just weird when his younger self didn't talk like that at all. Anime trope gonna trope I guess.
