Also posted this on the Pokemon Y boards to see if anyone had some info.
I was in the Lumiose City and I went into this building in the north section with multiple floors. It's the same one with the Kanto Karate Dojo guy on the 3rd floor. I get on the elevator and go up to the second floor and get off the elevator. Then the music stops and the lights flick on and off a few times and the last time it flicked this creepy girl appeared behind my character. She glides out from behind me on one foot like the game is glitching out in her walk animation and when she's right beside me she says "You're not the one..." and glides off screen and disappears.
Has anyone else seen this or know what it's related to?
Just saw her about 3 minutes ago in that building in North Blvd too. I wonder if she really will be resolved or not, but all I know is that that was much too creepy for me at 11pm after watching some Fatal Frame LPs the last week. >__<
