I have one little question.
Zoro come back. What will happen ?
1. Marco easily get defeated King and he go King . I dont think so. Marco wont get defeated easily.
2. Marco and Zoro will be team ? Likely.
3. Zoro will go rooftop again. We will travel Kaido past and yamato and kaido will fight each other for a while . I dont think so.
4. Sanji and Zoro will be team ? Non make sense.
5. Zoro will follow Orochi ? I guess Orochi is different place I dont think so.
the most possible action seems marco zoro team .
