Repair stairs south of Calcenon, go to the little cave/room by the stairs that gets accessible. Defeat the Woman in there (appears after beating the Ep 18 Leader). She says something about Carolina and basement key. Go to Agate, find the building with a kid inside that tells you something about a creepy basement room and asks you whether you want to see. Agree and the door to the escalator opens. Go to said basement (bring flash) and screenshot/memorize the pattern on the floor. Go to the Calcenon Gym. Recreate the pattern on the floor of the last room in that Gym (color of tiles changes once when stepped on). A door in the gym opens. go through and you find the woman again, she wants proof that you are a friend of Carolina (or at least not a meteor). Go to the Belrose House. Search the bookshelves for a Familypicture. Return to the Gym. Profit.
