Also for those of you who haven't experienced this, there's an office building in Lumiose City with three floors. The top floor is a dojo. If you go to the second floor and take a few steps forward you'll get a cutscene.
You should check it out for yourself.
Or if you're lazy, a girl randomly appears behind you, then beside you and says something like "No, you're not the one" and then walks off screen. If you progress in the room she's nowhere to be found. Her sprite looks like a hex maniac.
