Or he was implying another fishman
hmmm... so you're implying that Big Mom told Kaido that Jinbe has escaped and joined the enemy "SHs"????
hmmm.. maybe?
But I feel like the spoiler would have stated "your brother/cousin" meaning an individual reference to one specific guy... and not refer to a "whole family" being against him... right??
Also... it says Kaido threw an OLD PAPER... which makes me think it has "writings/words" however I feel if it was Jinbe... he would have given him a Bounty poster of Jinbe instead of an old piece of paper...
I don't know.. it's possible though... who knows.. we gotta wait and see the chapter to see their full design
