Yosh OPP crew, long time no write. Twofer question for ya.
1. Is there a slight possibilty that Shirley's prediction could be off. Her vision show that Luffy is in a completely breatheable area and considering Hody making such a big deal about the Fishman District and its chances it could survive the initial colony drop coming. Could it be possible that the destruction wasn't really meant for the island but that area of it?
2: Speaking of the Fishman District. Do you think his plan isn't just domination of humans but to have that section of the island be the dominate force of the island. Think about it; his comments last chapter seem to show he has a low opinion of mer-people, the island is ruled by such, it would give him a secondary reason to assassinate Otohime, he was quick to nearly kill Shirley over her prediction despite knowing her reputation and most of all they resemble humans. Granted it could be just him being a evil prick, but its food for thought.
