Thank you
@Lance_Dragonite for the full summary.
First of all, I'm glad that Oda kept the flashbacks short although it's a bit heart-warming, and Ace mentioning Cavendish is actually hilarious.
So Robin and Brook going up the castle on their own means Robin will probably go to replace Sanji against Black Maria, and probably Brook replacing Jinbe against Who's Who unless he backs Robin up. That way will be a set up to Sanji facing Queen/King (more likely it's gonna be Queen).
Marco is quite at a disadvantage here since King and Queen are blocking him and him holding Zoro with his leg kinda limits his way of fighting, unless he decides to let Zoro fights while he's holding Zoro with his legs or letting Zoro sit on top of his back. This is kinda hard to picture so we'll have to see.
I don't know what to say much about Kaido and Big Mom's part except that what a suprising DF it is. A fish model? Interesting.
Well, can't wait until the real fights start, which will happen on 2021, I guess.
