How is it that the Condesce could be present on both the alpha kids' earth and in their session? After she killed the handmaid did she travel to their universe or session? I would guess their universe, but then how could she get to the medium, especially before all the kids do? I cant think of any ways to enter the medium AND go back in time, and she doesnt seem to have her own time powers. Are there maybe two condesces, with the one in the medium being from the beta kids' earth?

There are teleporters to Prospit and Derse in the Frog Temple on Jake’s island which Condy had access to
