Act 3 end's on a tragedy.
The tragedy right now is an absolutely defeat.
Or the land of Onigashima on Wano.
If Zoro is against Kaido, he's gonna lose, if Sanji is against Kaido, he's gonna lose, if luffy is against Kaido, he's gonna lose.
Not that hard to understand, but seems so hard for Zoro Stans...
