He said you guys, while posing with his crew, the samurai are allied and helping him out, but are you seriously suggesting he wasn't saying it to his crew also? Odd take, but fair enough, you'll have to wait until further chapters come out to see if Luffy's crew assist him in getting up there, or if the nameless faceless samurai and Hyo are the sole mvps.
I'm on the fence as to whether Zoro will help his captain clear a path and stay down or go up with him. We will see in 10 chapters or so, it could go either way, to say that it will definitely go Zoro's way is also an odd take.
Luffy also said I'm going up to beat kaido, not we.
He didn't bother to look for Zoro when he was going up and just luckily saw him squaring up against Queen.
Luffy's priority is to go up and fight Kaido, if Zoro manages to keep up, great, if not, he won't wait for him.
