Well, it seems after failed attempt with Draco unspeakables try again but now they use Harry as perfect, willing victim. After all, he wants to go through maze to save friends. But what a twisted way! Use his trust, his willingness to help reach their foul goals.
He already maimed physically. It seems there’s more maiming on the way. It seems also that our heroes don’t realize for now that Harry is the next victim. Now I really, really want to see how Harry and Draco will avenge themselves. Revenge of person who cracked ancient riddle and then was betrayed and used must be remarkable.
I also hope that damage inflicted on Draco is not permanent.
