So Marco will try to take Robin, Brook and Zoro to the roof.
I expect King and Queen will try to stop them and will go as follows :
Queen manages to get a hold of Brook or Robin, and the other will stay behind to help. We get a short Brook + Robin vs Queen and then Sanji saves them and asks them to deal with the 3rd floor ladies while he fights Queen.
King stops both Marco and Zoro from reaching Kaido. Marco notices that Big Mom is going to become an issue on the rooftop and asks Zoro if he can handle King by himself, to which Zoro answers that he will be more than enough.
Zoro vs King and Sanji vs Queen awesome double spread for chapter 1000
