Issho will just say the safety of the citizens took priority over capturing the Straw Hats, which is a completely valid answer although Sakazuki will hate it. Something tells me he'll send Ryokugyu out to finish the job...

As for Joekido's question, I am sure Riku would be more than willing to give the Straw Hats a lift to Zo. Bartolomeo would also be very happy to give a taxi service.

Also, if there actually is a "Zo Arc" with an antagonist and all that I hope it's not just some random bullshit. If Zo Arc is a thing, I kinda hope that either:
 * Luffy and Law meet/confront another Supernova alliance
 * They confront an underling of either Big Mom or Kaido

Personally, I want to get to Wang Country as fast as possible so Kinemon, Momonosuke, and Kanjuro can finally be left behind and forgotten about.
