Zoro won’t be done before everyone. Either he is second to last done or the last. Ain’t no way Zoro is chilling before chopper or Usopp have defeated their opponent
I don't like saying it like this, cuz you're going to get people running with this to shit talk Zoro saying "Zoro was out before Chopper or Usopp". Fuck that.
I agree that the timing feels weird, but if he's not fighting anymore after this, we have to look at what he did until now, and anyone saying it's not incredibly impressive and praise worthy is crazy or just trolling at that point.
I want to see the pages when the chapter is out, but i do think Zoro doing what he did and saying what he did, has a different weight than it does for other characters. He's the last guy to casually say that he's going to give his all into one last attempt and then leave it to Luffy and the others. There's no way he goes ahead and says that if he feels like he has any fight left in him.
Zoro's not the kind of man to tap out of a fight if he can go on. Whatever happens next, everyone should respect that, and the way he did everything in his power, saved everyone's lives, and gave them this fighting chance.
