This chapter is awesome, it gives me hint that Sanj will unlock a new power that can be useful in combating with the yonko's, few years from now as Luffy becomes Pirate King, Sanji for sure will be a Yonko level alongside Zoro. ( I'm hoping before he leaves that place he'll wreck that Vinsmoke Family's ass).
