@Hinscher:
all the flashbacks were pointless then huh?
Absolutely not! never said that, never will. All flashback are a vital point of the story, like hancocks flashback. As I stated before It was there to make us understand Hancocks behaviour and to make the dragonpeople appear as total assholes ( as if the stuff in shabondy wasn't enough ^^). This flashback could even be used as a later plotdevice. Hancock vs. Worldnobles or sth like that. It just can't be used for another flashback. As onemoment stated,it would be recycling stuff we already know.
before we had nami's flashback we knew exactly what happened. Her island was under the control of arlong and she was stealing money for it.
We didn't know why she became a pirate and worked under Arlong.
Until her Flashback came, we thought she was a nasty little traitor. Then the flashback arrived and it turned into "HOLY FUCK what has this girl been through!?" The most important parts of her motives were only told in her flashback.
we knew reading poneglyphs was illegal and that robins whole island was destroyed, because they could read them and where.
That her Island was destroyed through a bustercall, was told exactly 1 chapter before the actual flashback. her flashback desribed neatly why she needed to live on, too.
we knew chopper had no friends at all and was thought of as a monster.
How he bacame a "monster" and his ambition to become a doctor/pirate were flashback exclusive material.
The only one we knew the most important facts before the flashback was Brook. Yet the flashback focused a lot on music and it's emotional value for brook.
So yeah it could be possible that a further flashback can be pulled. but it will for sure not deal with stuff we already know about Hancock. Maybe a certain key-event will trigger sth in hancock, sth. we yet haven't seen about her. I just can't see a flashback filled with childabuse and torture. Too cruel man! Too cruel! There must be more to it.
Just like we know Hancock was captured and a slave, or jimbei's island was saved due to whitebeard.
Jimbei will definately get a flashback don't know if it will be a small or big one. If Jimbei was a slave aswell, I could see a flashback of both Jimbei and Hancock together.
Edit: meanwhile we have camie who appears to have no background, just a clutz that gets captured. hatchi has nothing, he was with arlong and has achieved his dream already. Anyone who has joined we knew they were troubled somehow or before officially joining we already saw their backstory.
I think Camie could have a very interesting past! she's a mermaid afterall! People that were hunted down like valuable animals. and even her hometown was attacked, as Jimbei stated this chapter (if she actually comes from fishman island).
