It’s official. The grandfather is a comic relief sidekick.
I saw an earlier version of the anime in which the grandfather seemed to be a more respectable character. In this version, he seems to be a boke.
Some kind of boke is pretty necessary, because Jojo himself is a really mytho-poetic omnicompetent hero. Jojo can’t screw up comically; if he fails, he fails tragically.
