These plots just don’t matter to the straw hats anymore.
No one in Wano was ready to be a Nakama so that ended
Luffy doesn’t care about Pluton cause there’s no way he’d replace the sunny
And there was nothing they could do about SMILES
When we next see Wano outside of a cover story it’ll be cross guild or Blackbeard cleaning it up and ending these plots
Firmly disagree.
Chopper wanting to cure all disease ties directly into the SMILES, and this arc is centered around the foremost expert in Lineage Factor and Artificial Devil Fruits. Choppercan work with Vegapunk to cure them. Toko is a mirror of Bonney, pink-haired girl with disease from Celestial Dragon who gets cured by Vegapunk.
Robin and Franky are both very concerned over Pluton still, and would definitely want to act if Pluton was unleashed.
Luffy's last words to Momo include saying anyone who screws with Wano is screwing with the Straw Hats, and now we have Caribou about to feed Pluton's location in Wano to Blackbeard.
Tack on Zoro's past and there's a lot the Straw Hats have to do in Wano still.
