[[File:S1e1_3_book_code.png|right|thumb|200px]]I was wondering what other ciphers might the staff use in the future? We already know that the staff will purposefully not use a code until they are ready (see this picture). I noticed that one page in 3 slightly resembles a pigpen cipher (see image to right). I suspect they will use this cipher in the future. As the Wikipedia article states, its commonly used in media aimed at children because of its simplicity. Just a thought. What do you all think?
