That's not what I meant. My fault for rushing my initial post and not being more specific. I wasn't trying to say that Zunisha started at point A, and in 1000 years still hasn't reached point B.
We know there is a promised time, a New Dawn etc. etc. That time seems to be fast approaching. Zunisha has been wandering the sea for 1000 years, waiting for that time. Now is that time, and now is the time for Zunisha to start making her way to her destination. She's slow, and on path to where she needs to be. She can't alter her course, make it to Wano, and then be back on track to make it to where she needs to be for the promised time.
