I think Kaido needs to die in battle since being captured and traditional execution don’t work for him, Big Mom it’s in the air I think it depends on if Oda allows the homies to live after the host’s death since they are detached souls(thinking of Nami’s powerup), or she might just become Olin or brain dead permanently from her injuries. Firmly confident in Kaido and Orochi dying, despite Oda’s track record and I also firmly believe Big Mom is finished here. I feel this is setting up for a major shift in the world.
