Librarian - With a Match - In the Locker Room?

Due to the fire break-outs, the library was closed. Now that the library has re-opened, Princess Ash made her way back to the Castle of Books. Madam Librarian was standing guard at the entrance when Princess Ash arrived. Princes Ash smiled and said hello. "Where's your pass" said Madam Librarian in an unfriendly tone. "Don't you remember me" replied Princess Ash, followed by the showing of her pass. Madam Librarian examined the pass intently and said "This pass is from last semester and unusable this semester." Princess Ash then asked for a pass this semester. 'We are out!" replied Madam Librarian. "It's me, Princess Ash, remember?" With a blank stare on Madam Librarian's face she said again "Pass, please." Princess Ash is currently not allowed into the Castle of Books, again. What is the evil plan of Madam Librarian this time? Maybe it's to burn down the village (school). If this were the game of Clue, I'd guess the Librarian, with a match, in the locker rooms...but that's High School.
