At this point I have no idea who will fight who, I keep going back and forth.
Sommers feels more like a Sanji fight and Killingham feels more like a Zoro fight.
But at the same time, Sommers is probably near Zoro's location, and we know Killingham is with Sanji's group, and Oda could still have Sanji fight Killingham again and have Sommers fight Zoro.
Elbaf: Zoro vs Shepherd Family member and Sanji vs Mythical Centaur
Five Elders fight: Zoro vs Mythical Centaur and Sanji vs Shepherd Family member.
I do prefer Sanji vs Sommers because if we get Sanji vs Sommers, then imo there will be a much more higher chance of Sanji fighting Mars.
