About Emma...We don’t even know the all details about Wish Princess Emma. We know that the wish really created a world whose time is faster than NEF or LWM. But we don’t know if there is really another Emma, or if there is, we don’t know what happened to her after real Emma replaced her place (if that’s the case).

As you can see, lots of “if”s. I disagree for Emma I would love to see Emma have a Wish Realm doppelganger
