Long time eeee.
So here's a theory. First of all two mins of silence for three weeks break on manga. In chapter of reverie ending, even though the main news is abolishment of shichibukai. There were other news in side panels one related to Sabo which indirectly implies he died in the news. That obviously didn't happen as oda just killed one brother and revived another. That would make story too weak. And another one side panel had concerning citizen saying oh no but wasn't he one of three major powers of marine?
Well the news can't be one of admirals is dead as fujitora seems to have more important role in future and ofc green bull hasn't even been introduced. So no chance he is killed in intro😂😂😂
So I guess the nes is fujitora quit marine and joined revolutionary by seeing (and by seeing I mean feeling😂) the condition of Kuma and knowing the petty reason he had to suffer like that.
