Will be interesting to see if Kaido will be willing to kill her daughter. I know he used explosives cuffs on Yamato in case she left, but it might not have the same emotional impact as if he had to actually kill her with his own hands.
In either case, particularily interested in the Kaido - Yamato side story.
And this part is obvious in reference to her battle with rookie Ace
This will probably serve as a stalling plot until Luffy comes
