Sanji have a few pages at the beginning of the chapter who are the direct following of the last chapter cliffhanger.
You can discuss :
1-Where will this lead plot wise?
2-What is BM power and how it can hinder Sanji for the rest of the war?
3-Why Sanji did not use his CoO to avoid this trap?
4-Can Hell memories help Sanji to free himself from the web?
5-Will The RS play a role in this situation?
6-Will Sanji turn BM into an ally or it is just a way for Oda to nerf him?
There a lot of things to talk about the Sanji’s situation but you rather discuss if Zoro sneak attack Apoo or not
