But now that it seems she's been in Quadratum this whole time, it's looking like it's someone else. Possibly Skuld? I almost wanna say it's someone from Quadratum but crossing into another reality doesn't look simple so it'd bear the question of how they got there... Oh, however I'm completely convinced that the girl Lea and Isa are obsessed with is Skuld. That theory still holds strong. Maybe she's in Quadratum too, and that's why they can't find her. Or she's dead, and is the spirit. Not alot if evidence to go off of there but it's plausable.
