do not ask me why, but something tells me that it potentially also works similar to a stand arrow and can, under certain conditions, give people stands. it’s just a gut feeling that I have…So now Rohan gave jodio the lava rock, could it be related to rock humans or the rokaka or maybe it works similarly to the flow of calamity
Araki uses very specific wording in this chapter; they can't "steal" the diamond, Rohan "Lends" Jodio the rock. I think that the rock has a sort of ownership based power, where those the rock considers an owner cannot be stolen from. This would explain why the diamond no longer "came back" to Rohan, because Rohan extended ownership of the rock to Jodio, making the diamond and money both Jodio's and RohanWhoever theorized that there were multiple cats, was correct.
Still wonder why everything was magnetized to Rohan and now it’s not. Maybe that’s the effect of the Rock — to make valuable things yours.
