Yes this is still the big question left in my head as well. We still have almost no info on Mio’s mother. I was thinking it would turn out that she lived in quiet zero the same way that Eri lived in Aerial, but that doesnt seem to be the case. I also dont quite understand how Elan 4, Sophie, Norea, and all of the other’s who had died were all present in the data storm if they died far away from it. Does this imply that somehow all permet is linked?
