Yeah....somehow the situation will be solved on the wedding ceremony tomorrow.
It will be way too anticlimatic if they escape as they are.
Plus many hanging plot elements.
Pekom's fate,Capone's plot,the tea party that we heard for years...and no way is sanji going to let his sister die like this,especially when his kindness is mentioned again and again.
Oh..and Brook is locked up in the 4th floor with Big Mom.
Maybe Luffy reunites with Sanji,gets fed by him,make a plan about saving Raiju and then Luffy retreats in the mirror world for recovering for the next day.
