what does big mom going down even imply from a storytelling perspective?
for previous villains, it meant them being removed from where they were, Doflamingo from Dressrosa, Kaido and beast pirates from wano
but big mom being defeated does not mean WCI does not exist anymore, she can always come back and wreak havoc unless she is killed
big mom being defeated is one thing, what happens to her after is a whole different plot which is actually even more interesting and important
