@Kingdomkey:
Reading back I really like the idea of the SHs meeting a skilled fishman karate user at FI, but it's too late for that now I guess.
THIS. When the crew first arrived on FI ,I was under the impression Oda was going to introduce a new Fishman who uses Fishman Karate to join the crew , my initial theory was maybe a student of Jinbe or maybe even The son of Tiger or something cool like that ,but as soon as Luffy touched ground at the Sea Forest and Jinbe made the WTF face,it instantly made me realize that Oda wants Jinbe to be Luffy's fishman Nakama.[[when you read back to his to his 1st mention,it makes perfect sense]]
@Shift:
Though, I guess he could also swim ahead, but I hope Oda won't be so cruel…
I hope so too….But he hasn't been so nice lately has he? xDD First he ends Jinbe's official invitation to join on a cliff hanger ,then Jinbe abstains because of "unfinished business" but promises to join later,then he has Luffy get into confrontation with Big Mom indirectly becoming involved with Jinbe's said Business [[like most of us suspected]] Only for him to possibly leave FI off panel next chapter ,with a certain "who knows" feeling of when we'll see him again….cruel Indeed.
