With one of the Gorosei(Saturn) coming personally, should be interesting to know if he has any kind of power-level standing
I'm assuming though that Oda is doing that due to the fact they have higher level of authority over the Seraphims than even Vegapunk
Could also potentially lead to know the real reason why they seemingly needed Bonney that much. Are they aiming at capturing her again as some kind of last ressort to have someone who could turn them back to their prime continuously ?
Let's wait and see I guess
