And this info was not revealed in Wano...., why, exactly?
Okay, I was being coy. Sorry if I sound irritating, but look at it this way:
Cook had bloodline related storyline in WCI and played a part in stopping the ticking time bomb plot/Big Mom
Zoro didn't do or have either of those in Wano. So why should I still give Lolda the benefit of the doubt and think Zoro is related to Wano by blood at all?
