The 180 out of Pudding or Sanji? A bit of both, if you ask me. I kind-of wish the wedding does go through now! Oh Sanji, we should have expected you to pull off something like this.
Though... the bit about Pudding's ... secret (or her shame of it) is a surprise. Was not expecting even Big Mom to have something (= low opinion) like that.
A thought just occurs to me - there is a senior and extremely well-connected member of the press at the wedding. And Straw Hat Luffy, among all people just made an appearance. At the end of it all, how might this be reported? Hmm... a public notification that the fishman (forgot his name, dammit!) switched sides? That Straw Hat is full of surprises and a danger to the world?
Or a bigger question - will Big Mom retain her title as one of the four yonko? Hmm.... knowing Luffy, he'll try to take her on. And IF he wins (can't tell if he has plot armor this time), would he become a yonko himself?
The 7 warriors of the sea thing is something sanctioned by the World Government. But the four yonko? They seem independent as far as I can tell.
