I think Luffy and Zoro will follow the same path in this arc:
- Luffy fights against Seraphim.
- Zoro fights against Seraphim.
- Luffy fights against Awakened Lucci and defeats him.
- Zoro fights against Awakened Lucci and defeats him.
- Luffy fights against Kizaru and wins (which has already happened). Luffy should now focus on Saturn.
- Zoro fights against Kizaru and wins, and then goes to Saturn?
