        The time the Stand User tries to pretend to be Kakyoin, it’s immediately obvious.
        To most people, it wouldn’t be.  Sure, he’s acting strange, but they’re under a lot of pressure and it’s not like he’s known him that long.  But it’s clear this imposter, whoever he is, can get the physical details down, but the song is wrong.  Discordant.  A person’s song changes with their emotions, sure, but this is different, like someone’s trying to imitate a song by reading completely unfamiliar musical notation.
        Of course, it takes Jotaro a while to work out what the hell any of it actually means.  His first thought is ‘possession’, because it’s not exactly the same thing—he’s seen, and fought, a possessed Kakyoin before, the music is more a wrong note hit here and there, like some high school band’s first attempt at a song, not some…bad imitation.  But it’s not exactly like there’s a manual, and it’s not like he has anyone to ask.
        He’d briefly thought the old man might know, that this is how hamon works, but breathing is not gonna be his strong suit in a fight, ever, and he doesn’t seem to know anything about…he’s not calling it soul music, that’s just inane.  His questions about music had just sent jiji off on some rant about a parody artist, and the old man was so loud and obnoxious he didn’t bother to try to pry further to see if he knew anything useful.
                He doesn’t actually find out it means a fake until the man reveals himself, at which point he’s too busy fighting for his life.  But he files it away for later, just in case.  It’s not likely that they’ll run into another shapeshifter, but it’s worth remembering.

        (He only hears after the fact that there was, in fact, another Stand User with shapeshifting powers, morphed as him.  Yare yare daze.  Even he wouldn’t need some sort of extra ability other than Star Platinum to sense that one, face-to-face.)
