Well OP is out and since nobody has read it yet I guess I'm putting up spoiler tags.
Spoiler:
Luffy and co. eat the dragon while Luffy pretends to be a centar with Mr.Legs. Turns out the island it divided into a hot and cold location, Aura just might've called something.We then go back to the captured SH where we find the head to Mr.Legs chopped to pieces. Said head begins to commend on how he has to save his son and questions why Nami's only wearing a breast-piece.
Oh and it's implied tha Brook got away considering nobody would catch a set of bones.
