So this is my idea, theres another hidden prison on impel down where rox was kept. When blackbeard freed the prisoners one of rox followers who was imprisoned on lvl 6 in impel down like maybe his first commander free himself and destroyed the prison where rox was being kept.
perhaps thats the reason why rox became open during the reverie not because of bigmom and kaidou but hina was trying to get more information to an escaped prisoner who is rox. And this is also Probably the reason why garp said that hina doesnt have to worry because things always defy their expectation.
AND ALSO WHAT IF THE CERTAIN PIRATE THAT SHANKS AND GOROSEI WAS TALKING ABOUT WAS ROX?
