Why hide who shanks was talking about?
- Cause Oda likes obscuring the obvious so people make intrigue.
Why talk to the gorosei?
- Cause Shanks likely wants to create an alliance with the world government to take down Blackbeard before he becomes too powerful
Why during the Reverie?
- Cause Shanks knew a hot topic of the reverie was the abolishment of the warlord system, and knowing BBs greedy nature it’s the perfect time to set a trap for him and his crew
All of this goes along with Shanks’ previous characterization and previous goals and concerns.
- completely avoided my timeline question. Why didn't he go during the 2 years BB was devil fruit hunting?
- Your first point is not an answer. Oda hides information when it's meant to be surprising.
- Your second point is a guess. You don't know what Shanks is trying to do.
- Your 3rd point is even worse than the 2nd. It's a complete guess. And the Shichibukai abolishment was brought up during the Reverie by Fuji. How would Shanks know this on the FIRST day of the Reverie? What does this even have to do with Blackbeard lmao, he's a Yonko not a Shichibukai
