I think you are onto something. I just finished Sawyer7mages chapter 1067 Review and he brought up something interesting. Zoros sixth sense might be kicking in again. First the scene in Chapter 230 right before Robin left with Cp9.
Then again in Wano with Kiku.
And on egghead he stayed behind on the ship because he didn't trust lillith. We have yet to see what will result from that.
