(i think this has some spoilers for part 6 so i'll warn it here)
since Jotaro can stop time for 5 seconds with star platinum couldn't he have just ||used it to kill pucci once he arrived at the place Jolyne and the others were? couldn't he just like. Stop time, walk towards him, break his neck or smth and let time run again.|| And also since everything stopped I think C-Moon's gravity thing wouldn't be a bother to him would it
i'm genuinely curious about this because its very simple he could have just done this ig
