We've never got the punishment Sanji brought on himself for breaking the Pirate Crew code in fact leaving a Pirate Crew is the same as betraying the Pirate code
I know I'm late, but i dont get Nami here. Luffy forgave Sanji already. I get Luffy is the captain, but she holds a grudge more than him. Luffy aint dumb when it comes to his friends. Ah well.
Loki doesn’t even look angry at Big Mom trying to trick him, just sad, maybe even apologetic about the alliance falling through. I think this scene shows Loki is a very good person and ruler, and the Giants hate Big Mom more than ever because she disrespected him and made him more upset by trying to trick him.
