well it seems like luffy is going a step futher than he did with robin, he stoped at ennines lobby now hes going to do a jail break
if the 4empreior guys have 1bil plus bounties luffy will be joining this rank very soon
In fact this would be a huge jump in bounties for the whole crew, if they all too head to jail
for some reason i wouldn't be surprised if Zoro was already there, he's injured and i'm sure he's not on an isolated island, given to the marines thats a straight to jail card.
The others well who knows depends if they find out about ace and figure thats where luffy has gone, Otherwise this may become a luffy only arc until he bust out ace
