Did the chapter at least show what happened to Lily.........and new D family revealedm?? (whooahhh??? Fake surprise reaction), it's almost 1100 chapter couldn't careless. And I'm pretty sure Oda never planned ViVi to be D initially........
Reconstruction and change in the story happens during the Emperor Saga drastically
And out of all people Wapol could sneak such important sacred places and witness Imu existence like that easily......... whatever the plot demands so.
