And what's wrong with that? He'd make an excellent crew member. Besides, every new addition to the straw hats was after a big conflict so it's logical.
Jinbe has played such a huge role in the story so far that it would be dumb if he didn't join the crew. Granted Vivi also played a huge role in the crew at the time, but she is a princess. No bounty at all. Jinbe is a pirate, with an extreamly large bounty. There is no doubt in my mind that Jinbe will be the next additon to the crew.
im glad to hear SOMEONE saw this coming
Years after "leaving" the show he helped create, Darabont wants his cut.
