who dies in harry potter and the half blood prince
Harry Potter and the Half-Blood Prince (film) Dumbledore instructs Harry to hide and not to interfere no matter what happens. Draco arrives and disarms Dumbledore revealing that he has been chosen by Voldemort to kill the headmaster. When Draco is unable to bring himself to do it, Snape casts the killing curse instead. Harry confronts and attacks Snape, but Snape overpowers him, and reveals himself as the Half-Blood Prince before escaping. Harry returns to Hogwarts, where the students, staff, and a few guests mourn Dumbledore's death. Harry later reveals to Ron and Hermione that the locket Horcrux was a fake. The locket contains a message from "R.A.B.", stating that he has stolen the real Horcrux with the intent of destroying it. Rather than returning for their final year at Hogwarts, the three decide to hold out, and track down the remaining Horcruxes.
Harry Potter and the Deathly Hallows – Part 2 Voldemort triumphantly announces Harry's apparent death to everyone at Hogwarts, and demands that they all surrender. As Neville gives a defiant response and draws the Sword of Gryffindor from the Sorting Hat, Harry reveals he is still alive, causing the Malfoys and many other Death Eaters to abandon Voldemort as they realize he failed to kill Harry again, and any hope of victory for the Dark Lord is now a lost cause. While Harry battles Voldemort throughout the castle, Neville kills Nagini with the sword, leaving Voldemort vulnerable, and Molly Weasley kills Bellatrix in the Great Hall. Harry and Voldemort's battle ends with Voldemort's own Killing Curse rebounding and killing him, once and for all. After the battle, Harry explains to Ron and Hermione that the Elder Wand had recognised him as its true master because he had disarmed Draco, who earlier had disarmed its previous owner - Dumbledore - but, instead of claiming the Elder Wand, Harry breaks and discards it.
