Trivia

 * In this part the Stand Arrows are introduced. It is explained that this is how DIO awakened his Stand, and we know this because Joseph uses Hermit Purple to uncover an image of Enya holding the Stand Arrows.
 * The Stand Arrow is added into the background of a scene in the Stardust Crusaders anime so that this explanation makes more sense.
 * We are shown three different Stand Arrows existing in this world in this part and the one before. The one that belonged to the Nijimura brothers, the one that belonged to Yoshiro Kira, and the one that was in the hands of Enya the Hag.
