its more the fact that I dislike how Oda purposefully witholds "mysterious" information without logically addressing it. A big one is Luffy's fruit magically being the best Zoan of an ancient god. The Gorosei were never concerned about it before Wano, then all of a sudden they were.
Its the same with "Pranks". Chapter 907 reveals a literal doppelganger with the Gorosei, and yet Shanks or anyone has zero opinions on it at all yet. But watch, if this person is a completely different person, we'll get lore drops from people like Garp or Mihawk or Sengoku or Shanks immediately knowing this person existed and just never mentioning it in 1200 chapters. I just dont like how Oda lays up twists sometimes.
- Shanks doing something shocking like visiting the Gorosei because he's a secret CD. A good twist because we know nothing about Shanks' life
- Shanks having a twin like Sanji has quadruplet brothers....not a good twist since 907 comes out of nowhere about it with zero indication a twin existed. Like sanji's brothers dont even look exactly like him. They are genetically engineered and have different hair and features. This bro allegedly also has Red Hair, facial hair, etc with no genetic tampering? (Again not a clone because Vegapunk invented cloning after Shanks was born with Weevil and only was successful with Stussy)
