The comment in the anime thread wondering if Kira was a natural Stand user or if Keicho shot him with the Arrow made me think about how clumsy it is that Araki tried to shift into the evil Stand users fighting the heroes to protect Kira plot by... giving Kira a second Bow and Arrow, with very little explanation.
Ever since Part 4 was announced I've been wondering if they'll ever explain that a bit more*. Like, Yoshihiro makes it sound like he just randomly met Enya in Egypt and was given a Bow and Arrow; he didn't seem to be a pawn of DIO like the Nijimura dad, so what happened there? Did Enya just sense this guy was a potential Stand user with a fucked up kid? Did she have a special sixth sense to detect other old parents of serial killing sons, and give Yoshihiro the Arrow out of camaraderie? Did DIO think it sounded like a hoot to randomly give a serial killer's father a superpower arrow? Did DIO feel Josuke's presence in Morioh, and in some hippy bullshit speech with Pucci decide that it was "gravity" that brought another Morioh resident to him?
Then that last part made me realize that despite Stand users gravitating to other Stand users, that Kira and Josuke have both been living in Morioh as probably its only Stand users for years and nearly hitting Koichi is seemingly the first time they've encountered each other.
*I've also wondered if they'll at least add a throwaway line of Joseph saying that he's tried Hermit Purple to find Kira but he doesn't have enough information or Kira's mental desire to be hidden is too strong or whatever
