So Oda puts Sanji with the weakling trio, like I suspected. Who else is gonna protect them.
But we also have the strategic trio Sanji/Nami/Usopp in this group. They should prove a very dangerous component of the assaulting force in that respect(if Oda hasn't forgotten about his own characters, that is).
And what do you guys think is the significance of putting Sanji on the top of the tank instead of inside it? Will he eventually be separated from the group to do his own thing?
