Well Brook’s fruit is different since it hasn’t reincarnated… If Momma dies and her fruit reincarnates then that’s a whole other deal... The mere fact that homies were affected by whatver mental state Momma was in Tells me they are way too connected to Momma’s well being for them to obtain autonomy from the fruit itself
That doesn't really seem consistent if they are also so capricious and can act against her interests. If Zeus had been kidnapped rather than going along willingly then maybe I'd believe it but for now I'm not sure.
