Assuming the spoilers are all legit, I'm a little bit worried about Marco and Perospero.
Their common enemy is King most likely, i can't see a clearer goal for their supposed alliance.
Sanji vs King is too much but even tho i would like interferences in the fight by Perospero's part, Marco joining it would be a bit too much.
I would be fine with Marco interrupting them and treat Sanji, Luffy escaped and was helped countless times in his "1 vs 1"s, but i hope he leaves King to Sanji almost immediately. Our boy deserves it
This if Zoro and Sanji doesn't fight King or both King and Queen together
