Paper saying something might be weird as fuck oh God, Oda really fucked up big time
Lol, only if they don't explain why the Gorosei didn't go after Luffy prior to 1037.
But think about it, they were going after Robin until that chapter. Then something happened. Something made them realize that they needed to kill Luffy. Before this they knew Luffy was fighting Kaido (CP-0 did especially), but it was only after certain moment (Zunisha?) that it made them think they should kill Luffy. One of them even remarks "its impossible!" Indicating they never believed Luffys fruit was related to Nika. In 1041, they mention this was a rumor.
So something is definitely up here of the dialogue is this delibrate. But yes, it would be stupid for it to not be. So either this just because there is a lack of spoiler dialogue, or Oda is saving it for a later chapter because a he doesn't want to make obvious if someone (Shanks?) told them about it.
