-As Yamato runs to help Luffy as he falls from the sky, we see the narrator update the situation of the Wanokuni battle. Kaidou was the winner of the battle on the roof, but... - "Wanokuni, Decisive Battle in the Skies. Winner: Straw Hat Luffy"
Bigger problem is Zoro's potential backstory/lineage is going to get shoehorned at the end here when it doesn't really feel like it matters anymore. Who cares if Zoro is a Shimotsuki at this point, nothing interesting is going to come from it. And I doubt anyone in Wano will even know.
