One thing I've always wondered.
Does Hazamada still have a stand? I know Josuke broke the doll into bits, but going purely off of how stands work shouldn't that have killed Hazamada? Unless it's a super long distance automatic stand that works without the users input, when your stand is destroyed you die; DIO can attest to that. (And even then if you "kill" a long distance stand it always comes back).
I'm just asking because even though we only see Hazamada once or twice after this, there's never any indication that he still has Surface.
Maybe he just doesn't use it, or like…does he have to have some sort of medium to channel it though? If he were to come across a department store dummy would that become the next "surface"?
My thought was he needed an object for his stand to be effective. Then after watching the episode Yamada mentions that once changed even non stand users can see it, so there's that. If someone else saw the dummy then that would answer the question a bit better. I guess Araki didn't think it through all that much and decided it wasn't worth trying to explain.
