I rewatched the episode and when she touched the Sphere of Life he saw scenes from "Before The Flood". I noticed Syd and Nadia fighting, the Muttler Device and Nadia with freaky eyes. So I guess it was all meant to happen'. And that Nadia "died" as the prophecy told. From a certain point of view that is. Her persona is lost. I bet Nadia will be in some hospital for the whole next season. I mean Mia Maestro is gonna be in only 3 episodes. Just when I was really beginning to like her. No!!! I mean LOVE her.
