Did you not read the spoilers? The spoiler says Zoro stops Queen, so Zoro fighting Queen might still happen. Not saying the fight is a guaranteed but the possibility is still there, don't be salty if the fight you wanted with King doesn't happen.
Nah, that happen before Zoro talk with marco which indicate that the clash is alredy over.
What do you think can do Queen against: Drake,Marco,(the remaing strawhat such Chopper,Brook,Robin and Zoro)?
Keep in mind that Zoro in the last chapter said that he want to go on top, right now there is no more plot to hold him back cuz Chopper got the cure, Marco is there to help them, Drake has something open vs Queen.
The possibility is equal to 0
