Who's who appears! I wonder if he is targeting King since it's not Queen. Queen might be targeting Sasaki.
Since King and Queen are together the target should appear at their location.
It would be funny if Zoro fought Who's and Sanji fought Sasaki, who also appears to be a swordman. I can see Oda doing that. As a mini fight.
On a side note, I would love for big mom's army to appear. That would increase the chances of the Straw Hat Grand fleet arriving.
