This season goes around Harry’s sixth year at Hogwarts. The first thing is to welcome a new professor, Horace Slughorn, who teaches Harry a lot of amazing things about poison. In the movie, Slughorn gives Harry a tattered book which belonged to The Half-Blood Prince that has many scribble notes in the margin of each page with tips to help Harry progress in magic. One more thing is Dumbledore opens a class for Harry and he even shows Harry views the memory of the dark secret of Voldemort in the past.
