What language, or languages, do you think are being spoken by the cast in Stardust Crusaders?
As an English speaker, I am incredibly biased, but I have always seen SDC as being spoken almost entirely in English…
With a couple of exceptions.
First of all, why do I believe it’s spoken in English? Well, mostly because of the fact that the characters can talk to Dio, and I doubt that Dio somehow learned Japanese while stuck in a coffin under the ocean. And then there’s Joseph, who says a lot of phrases in English even in the Japanese dub. Take into account that English is often used as a language when trades occur across borders, and somehow it just seems the most likely to me.
Otherwise, perhaps Jojo takes place in a universe where everyone speaks one language. We rarely, if ever, see communicative difficulties, even when the crusaders are in rural areas populated by folks who probably don’t speak English and definitely don’t know Japanese.Now, for the exceptions. If the cast is speaking in English, I believe that Jotaro and Kakyoin have conversations in Japanese just to piss off the “old guys.” Joseph probably speaks Japanese as evidenced by his ability to talk to everyone in Morioh, but it’s likely harder for him to speak Japanese than English, and he takes a bit longer to process it.
Polnareff probably says various things in French to flirt with random passerby and to sound romantic/cool/mysterious. In his mind, of course. I doubt that any other members of the crusaders take his French seriously, and laugh at his attempts to sweep fair men and maidens and anyone with a pulse off of their feet.
I headcanon that Avdol is a polyglot (meaning that he knows many languages), and as such speaks to locals in their native tongue. He’s the group’s translator whenever they encounter someone who can’t understand English.
And finally, when it comes to skill in speaking English, Joseph is obviously the top dog with it being his native tongue, with Jotaro just behind him. Holly is a native English speaker, and probably used it around Jotaro all the time as a child, so he knows it almost as well as he knows Japanese. Avdol is a language geek, so he’s just after Jotaro. And finally, Kakyoin and Polnareff are tied in last. Neither are at all bad at speaking English, but have had less practice than the other three. Kakyoin probably looks to Jotaro sometimes for help if he’s forgetting a word, a service which Jotaro begrudgingly provides. Polnareff just continues on without even knowing what he’s saying. I imagine that every so often he’ll say something that sounds as if it was conjured up by google translate; he’s so confident in his charisma that he doesn’t care if he gets a phrase wrong here or there. People will love him anyway, right?
