I remember seeing a video by Game something (forgot their full name xD) amd when the camera zooms into you in a walking motion it's actually through that girls prospective
She reappeared on Mt. Pyre. There's a Hex Maniac there that says the exact same lines as the ghost girl in X/Y. I would expect an explanation (if any) in Z, like how the ghost girl in Black/White was explained in Black 2/White 2.Has the 'ghost girl' form X and Y had an explanation yet, or are we just forgetting that creepy b**** existed?
wait how come i never noticed her before?
