Currently, this interest me the most ,if someone else thinks it is related to the fact that Marco will heal Zoro instead of choper ???
Of course , it couldn't be though contrary.
We have already known chopper will transform his original form in 5 minute.
And chopper don't have a magical Wand . Until today he did not heal anybody in 5 minutes. In 5 minute , chopper will be out of arc during 2 3 hours.
Zoro can be healed just Marco sacrifice.
But Marco vs King will not end in 1 2 chapter.
Oda will do again same thing.
Zoro appeared 10 chapter and sanji lost.
Sanji will appear 10 chapter and zoro lost.
But end of the day, main question if oda did like that , that means zoro and king will fight after queen vs sanji end.
What will happen after that point?
Also Marco will follow his captain with this arc I guess
