I've been thinking about the rate the series is going and we are no closer to Fishman Island than we were back in chapter 433 "The Name Of The Sea" and Kororo said Fishman Island was the next island Luffy would encounter. OVER 100 chapters ago we have yet to make it there and I fear it will be longer still. I have a theory that Oda's been avoiding sending them to Fishman Island because he likes to watch us suffer. **In chapters 523 and 524, Strawhats are seen on various islands spread all over the world.
That being said how many Strawhat Pirates will actually make it back to Shabody Archipelago? How many will need to be rescued themselves. Let's go over the facts shall we.
Nami is on the sky island called Weatheria with a kooky wizard man who makes the wind blow by untying rope knots. Assuming from what we've seen over 500+ chapters I believe she'll make it back to Shabody with little to no complications.
Franky is on a snow island called Karakuri Island in the "Future Kingdom Barjimoa" somewhere in the Grand Line. He's going to build a boat and make it back no problem.
Sanji (who could forget) is in Hell (Momoiro Island) and is surrounded by transvestities. He is going to escape no matter what and make it back.
Usopp is at the Boin Archipelago in the Grand Line. Stuck with a guy named Heracle who adds "-un" to the end of every sentence and in a forest that eats everything it is possible he might need rescuing unless Heracle feels the need to help Usopp out.
Brook mistaken for Satan by some poverty-stricken, revenge-seeking locals of Namakura Island without doubt will return because of his bond with Laboon.
Robin. Now there's one member that might need rescuing. In chapter 524, Page 7, Robin had a pair of shackles forced onto her in the Bridge Country of Tequila Wolf. Now we don't know if those shackles have those sea stones in them that render DF Users helpless or if they are normal. Depending on the answer if they aren't seastone handcuffs she might possibly make it back if not this is where Oda might put in another arc before Fishmen Island.
CHOPPER WAS SENT TO THE SOUTH BLUE?! Oh yeah! If he wasn't completely useless he might find his way back. But here is another way Oda might put in another arc.
Zoro ended up on Perona's Island of Kuraigana. I see a possible chance of Zoro making it back to Shabody with Perona and everyone being in their running gag faces saying "Why the Hell are you hanging out with that woman?" It'll happen. Just you watch.
So we have the possibility of Ussop, Robin, and Chopper needing to be rescued before reaching Fishman Island.
Let me know your opinion.**
