speedwagon had to die after part 2 because part 3 would have been ten minutes long. holly joestar gets sick? speedwagon himself flies to egypt without being targeted because he isn’t a stand user and with the help of a handy dandy speedwagon foundation wrecking ball he destroys dio’s mansion and straight up kills him for daring to breathe at a joestar. part 3 over. part 4 never happens because speedwagon confiscated both stand arrows. bang.
