We could all have been killed - or worse, expelled.
Of course it is happening inside your head, Harry, but why on earth should that mean that it is not real? No story lives unless someone wants to listen. The stories we love best do live in us forever. So whether you come back by page or by the big screen, Hogwarts will always be there to welcome you home.
Things we lose have a way of coming back to us in the end, if not always in the way we expect. It is the unknown we fear when we look upon death and darkness, nothing more. It takes a great deal of bravery to stand up to our enemies, but just as much to stand up to our friends. It does not do to dwell on dreams and forget to live. If you want to know what a man’s like, take a good look at how he treats his inferiors, not his equals.
