Over at Pottermore Insider (you need to be a member to view the link), they've been dropping #PottermoreTricks leading up to Halloween. All signs seem to point to Professor Sybil Trelawney for this one! (We have to admit, a quick Google search of "RS Hawker's Song" led us to the answer. Ha!) What do you think?
On Pottermore, it says, "In brand-new exclusive writing, soon to be released on pottermore.com, J.K. Rowling reveals her inspiration for naming this mystery Hogwarts teacher—can you guess their identity?" Who's your guess?
Are you on Pottermore? What house are you in? Are you excited to read more about the Divination teacher? Leave us a comment below or tweet us @candymagdotcom to join the conversation.
