memory is the key

What is Zoro? Zoro is gravity. He's not the loudest voice, he doesn't explain himself, he does not flinch. Zoro is the thing that stands still when everything around him movies. Pain doesn't impress him, danger doesn't rush him, he's never trying to win the moment, he's just enduring it. Sanji is motion, and Sanji is emotion. Sanji is juxtaposition. Sanji is everything on either side of that. He is equal parts completely silly and childish and reactive, as he is tense and driven. Both of those require movement. He reacts, he adapts, he fills the space. Where Zoro absorbs pressure, Sanji kicks it away, or cooks it away. Where Zoro goes through the threat, Sanji moves around the threat. They are complete opposites, but they're not necessarily rivals. I see them as counterweights.
