This whole ''tragedy'' is so unnecessary...i have the Feeling Oda just wants to slow the whole thing down...just give us the end fight already...
Now we will easily be wasting time for atleast 10 chapter to solve this ''mystery''...
The pacing was so slow the whole Arc, but at the end he started to skip days and all were thinking now we are doing some Progress. And on the fight day, where everybody was Ready for the Action - Oda uses the handbreak...
