The second film especially opens where the Part one concluded as the Heroic Trio have secreted themselves Harry determines that the must break into the vault of Bellatrix where the second foundation Horcrux is thought to be held. It is the destruction of these objects which will lead to the end of the great baddie Voldermort who has taken power over the World of Magic and the Education academy of Hogwarts.
Hermione uses a shape shifting potion to appear as Bellatrix and they taken along the Goblin Griphook. The vault is in the bowels of earth involving a dangerous helter-skelter ride and although they enter the vault they encounter a problem as everything they touch multiplies exponentially. Griphook tries to turn the tables when exchanging the Horcrux for the sword but the trio manage to escape on the back of a dragon similar to a prehistoric flying creature.
They return to Hogwarts and oust Severus Snape the important link with Harry‘s parents, especially his mother, and the double game he has played all along. Ron and Hermione go to the Chamber of Secrets and destroy what had been hoped was the remaining Horcrux. However they have worked out there is another Horcrux after Harry has confronted the spirit Rowena Ravenclaw and this is a diadem in the Room of Requirement. Malfoy their constant adversary and former fellow pupil and two others attempt to foil Harry who is rescued by Ron and Hermione but then find themselves engulfed in the flames of a fiend. They only escape using broomsticks, with Harry deciding to rescue Malfoy. Ron makes one of the few jokes that he will kill Harry if they die rescuing their adversary.
The remaining Horcrux is destroyed leaving just the snake familiar.
The Death Eaters and Voldermort besiege Hogwarts, while Harry, Ron, Hermione, their allies, and various
magical creatures defend the school. Several major characters are killed in the first wave of the battle, including Remus Lupin, Nymphadora Tonks, and Fred Weasley. Voldermort has pleaded with the school to give up Harry or be killed.
Voldermort then kills Severus Snape because he believes doing so will make him the Elder Wand's true master. Harry finds him dying and uses a utensil to capture the tears of Severus who urges Harry to use them to discover the truth about the overall story and its outcome by consulting one of the devices which has enabled Harry to see back as well as to the future.
There are two revelations which astound Harry and turn everything on its head. The first is while Harry’s father was not the hero that been assumed it was Severus who had adored Harry’s mother and attempted to save and then Harry. He had been a double agent throughout pretending to be on the side of the Dark Lord as a means of guarding Harry and had done this with the full knowledge of head of school Professor Dumbledore.
It was Dumbledore with only a year to live who had asked Snape to kill him as a means of saving the soul of Draco Malfoy who throughout had acted under the influence of his parents who were servants of Voldermort.
However the main and most challenging revelation is that when Voldermort had attacked the one year old Harry he had made the boy into a Horcrux which means that Harry had first kill the snake and then let Voldermort kill him so the dark Lord would be destroyed by his own hands. This presents Harry with his greatest test.
After using the Resurrection Stone to bring back his deceased loved ones for a short while and to ask them about the moment of death and to be with him as he surrenders himself to death at Voldermort hand. Voldermort casts the
Killing Curse at him, sending Harry to a limbo-like state between life and death. There, Dumbledore explains that when Voldermort used Harry's blood to regain his full strength, it protected Harry from Voldermort harming him; the Horcrux inside Harry has been destroyed, and Harry can return to his body despite being hit by the Killing Curse. Dumbledore also explains that Harry became the true master of the Deathly Hallows by facing Death, not by seeking to avoid or conquer it.
Harry returns to his body, feigning death, and Voldermort marches victorious into the castle with his body. However, he shows that he is still alive while
Neville Longbottom kills Nagini, the last Horcrux, with the Sword of Gryffindor. The battle resumes, and Bellatrix Lestrange is killed by Molly Weasley.
Harry and Voldermort engage in a final climactic duel. Harry reveals that because he willingly sacrificed himself to death by Voldermort hand, his act of love would protect the Wizarding community from Voldermort in the same way the sacrifice Harry's mother made protected Harry. Harry also reveals that Snape was never loyal to Voldermort and did not murder Dumbledore Voldermort, who murdered Snape, was never the master of the Elder Wand. Draco was the master of the Elder Wand after disarming Dumbledore, but Harry disarmed Draco at Malfoy Manor, making Harry the true master of the Elder Wand.
The wand refused to kill the one to whom it had allegiance, further protecting Harry. During the duel, Harry refuses to use the killing curse and even encourages Voldermort to feel remorse, one known way to restore Voldermort shattered soul. Voldermort dies when his own killing curse backfires; he and his Death Eaters are finally defeated. The
wizarding world is able to live in peace once more. Harry breaks the wand and throws it into the deep.
There is a splendid epilogue some nineteen years later and once again the train departs from platform nine and three quarters for Hogwarts. But this time Harry is there as a parent to see a son off to school for the first time. There he meets Ron and Hermione who are married and are also there to see one of their children off to the school. For a moment the trio stand together as the train moves out. Also present at the departure is Draco Malfoy and his family seeing off their son Scorpius
Ginny Weasley have named their three children: James Sirius, Albus Severus, and Lily Luna Harry's godson, Teddy Lupin, is found kissing Bill and Fleur Weasley's daughter Victoire in a train carriage. Harry tells his son Albus, who is worried he will be sorted into Slytherin, that one of his namesakes, Severus Snape, was a Slytherin and the bravest man he had ever met. He adds that the Sorting Hat takes one's choice into account, like it did for Harry.
I am told the book ends with these final words: "The scar had not pained Harry for nineteen years. All was well."
But is it really the end? I enjoyed seeing the author at the Olympic Games opening ceremony as well as her appearance at the Leveson Inquiry. I have come to appreciate the series more with several viewings, not have read the books and found the individual films difficult to understand without an appreciation of the overview.
