Maybe it might be a good idea to include some spoilers from past episodes that help explain somethings in these episodes for those that are new to One Piece or don't remember what happened since the series last aired on Toonami in 08.
I am only posting stuff that are important to this episode only, and with this one it's mostly common knowledge stuff anyway, so nothing too big.
Like I said, common knowledge. Nothing like the floating octopus and Donquixote Doflamingo and the Bellamy pirates last week. But, I hope it helps.
