This is set up nicely for Luffy to have to get past Queen, and then King afterwards in that order to reach Kaido.
I bet Luffy, Zoro and Sanji will eventually split from the group and aim for the roof.
Sanji will have to engage Queen so that Luffy and Zoro can go on.
Zoro will have to engage King.
Luffy will defeat the flying Gifters and reach Kaido.
Zoro will eventually join the Kaido fight later on after he defeats King.
