It seems that Sabu managed to save Vivi and escape...Sabo is probably a secret witness and needs Vivi's testimony to prove his innocence
And there is a more important question...Why did Imu have Vivi's picture?
It doesn't make sense, but it seems that Vivi may be an important character...Bb may also want to capture Vivi
Luffy has one less crew member and also Aokiji is a big problem...If bb is the next enemy, it all depends on aokiji's role...Sabo has a decent ability to fight him
what is your opinion?
