Question: I know that I've seen a clip of Narcissa telling Voldemort that he will always be welcome at the Malfoy's house (she does not say this in the book). Is there an extended version of the scene somewhere?
Question: Ron, Harry, and Hermione use polyjuice potion a lot. I'm confused as to how this is. In The Chamber of Secrets it is revealed that it takes a month to make. It would seem unlikely that Hermione would carry around a cauldron and potion ingredients and waste a month making the potion after they had a plan. If Hermione had made them over the summer, she would have only had time to make a few before she would have to leave with Harry and Ron. How do they get all their polyjuice potion?
Answer: It's explained a little more in the book. Hermione swiped Mad-Eye Moody's stock of the potion when Mrs. Weasley wasn't looking. And it's possible that, when they ran low, she simply replicated it with a Doubling Charm.
Question: This is a two part question. 1) If Snape wants Harry to have the sword of Gryffindor, why would he place it at the bottom of a frozen pond instead of placing it somewhere more accessible? 2) Does the locket try to choke Harry because it senses the threat posed by the presence of the sword?
Answer: 1) Snape's motive for hiding the sword in the pond is never explained "in the movie." As for the book, it explicitly states that Dumbledore instructed Snape to give the sword to Harry when possible, but make so it takes bravery and courage to acquire, like a true Gryffindor. Snape then found they were in the Forest of Dean, and he himself placed the sword there. 2) The Locket was partially sentient and could sense that the sword was a danger to it.
Question: Why is it necessary for Draco to confirm that the real Harry has been captured by the bounty hunters? Lucius and Bellatrix have each dealt with Harry before.
Answer: Lucius and Bellatrix were unable to confirm Harry's identity because Hermione had jinxed his face to disguise him just before the snatchers captured them. They are fairly certain it is Harry, but as Bellatrix says, if they summon Lord Voldemort, and they are wrong, he will kill them all. Of all the Death Eaters at Malfoy Hall, no one knows Harry better than Draco, having spent more time with him because they were schoolmates. Lucius and Bellatrix have to be absolutely sure that this is Harry Potter.
Question: Why does Bellatrix accuse Dobby of defying his "masters"? Surely she would have heard from Narcissa, Draco, or Lucius that he no longer serves the family.
Answer: That would hardly matter to Bellatrix. She would look at Dobby as an inferior being who was fit only to serve wizards. She likely considers him to still be her sister and brother-in-law's possession, despite Harry's freeing him. Most wizards see their race as "masters" to all house-elves and other non-human sentient beings, regardless of whether or not they were free.
Question: Draco said in the previous book/movie that Voldemort would kill him if he didn't kill Dumbledore, so why didn't Voldemort kill him after he refused and Severus had to do it instead?
Answer: Draco didn't refuse outright, though he did not want to kill Dumbledore. Voldemort threatened to kill Draco's family if he failed. Draco did make attempts, but they were half-hearted ones that failed. Snape stepped in before Draco was forced into killing Dumbledore. Voldemort would have killed Draco eventually, but keeping him alive was useful in his controlling both Lucius and Narcissa Malfoy (Draco's parents) and also Bellatrix Lestrange (Draco's aunt). Killing Draco early on would have turned them against him.
Question: What happened to Hermione's cat Crookshanks? He's not seen at all at the start of this movie. I can't remember if it's mentioned in the books what happened to him; the movie doesn't seem to mention it either.
Answer: The last time we see Crookshanks is at the Weasley house. They likely left him there.
Question: I don't remember if this is explained in the book, but when it is discovered that Umbridge has the locket, assuming she wore it while she had it, wouldn't she be possessed by its powers like Ron was when he wore it? And did she know it was a piece of Voldemort's soul?
Answer: This was never answered in the book, but in The Muggles' Guide to Harry Potter, it is speculated that Umbridge may have been unaffected because her own evil nature was more aligned to the dark locket. Also, the locket being somewhat sentient may have sensed that she posed no threat to it, whereas Harry, Ron, and Hermione's sole intent was to destroy it.
Question: This question is more of an overall question for the series. In Half-blood Prince Tom Riddle asks professor Slughorn if it is possible to create 7 horcruxes. In the movie, once the locket is destroyed, Ron says to Harry "3 more to go". If my count is correct, they destroyed the diary, Dumbledore destroyed the ring, and now the locket. That would leave the goblet, the diadem, and Nagini. In total there are only 6, and at this point, neither Harry nor Voldemort know that Harry is the 7th. So basically the question is, if Harry knew that Voldemort Planned on making 7 horcruxes, why do they only search for 6? Is it possible that I am completely overlooking a major plot detail?
Answer: Voldemort wanted to divide his soul into seven pieces by making six Horcruxes and leaving one soul shard inside his body. The number seven was considered to be the most significant and powerful number in the magical world. He made six Horcruxes using Tom Riddle's diary, Marvolo Gaunt's Ring, Helga Hufflepuff's cup, Salazar Slytherin's locket, Rowena Ravenclaw's diadem, and Nagini. Harry Potter was also a Horcrux, but that was never Voldemort's intention. He accidentally (and unknowingly) created a seventh (sixth at the time - Nagini came later) Horcrux when he attempted to kill baby Harry. Dumbledore had correctly speculated to Harry that Voldemort's plan was to create six Horcruxes while leaving one soul piece inside his body.
Question: Is there any other way that Hermione could have possibly protected her Muggle parents from Voldemort and his followers besides erasing their memories, like casting a protection spell over them similar to what was done with Harry for the past 17 years or taken them to the Burrow to be protected, or even Grimmauld Place?
Answer: Any of those options would provide some degree of protection, but, should Voldemort ultimately triumph, it's extremely likely that those measures would eventually be circumvented by his forces, leaving her parents entirely at his mercy. By erasing herself entirely from their memories, they cannot be used against her, as they cannot be linked to her (it's reasonable to assume that Hermione would also have arranged for any files linking her to them or that address to be destroyed or altered as well). Erasing their memories also has the side effect of sparing her parents from grief should she fall in the ensuing conflict.
Question: Why do all of the Death Eaters hesitate to lend Lord Voldemort a wand? In "Chamber of Secrets", when Ron's wand was damaged, Professor McGonagall just said he would need to replace it. So I am assuming that purchasing a new wand is not particularly unusual or difficult.
Answer: Normally replacing a wand is easy, but there are only a few wizards who can make them. Voldemort has kidnapped Mr. Olivander, tortured him, and destroyed his shop, so he is not currently in a position to be making new wands. The Death Eaters fear offering their own wands to Lord Voldemort because he often strikes out, often fatally, at anyone who fails or displeases him. If someone gives him their wand and it does not perform adequately, they know there may be severe repercussions. Voldemort is also gauging his Death Eaters' reaction to his request so he can judge their loyalty and willingness to do his bidding. Most also realize that the request is mostly aimed at Lucius Malfoy, who has fallen from Voldemort's favor. Voldemort is taunting him.
Question: In the movie, the team of snatchers were able to smell Hermione's perfume through the protective spells that she put up. This may seem silly, but why did she have perfume on? It seems quite careless on her part and there was absolutely no reason for her to have it on for their mission, so why the perfume?
Answer: They aren't exactly staying in 4-star hotels and showering every day. Camping is dirty, and with that comes certain odors. And that can get unpleasant in close quarters. It's likely the perfume was her way of countering that. In that instance, sure, her perfume may have been a tip off, but it's not unreasonable to assume that that doesn't come up all that much.
Question: If Dumbledore knew who Tom Riddle/Voldemort really was, then why take him to Hogwarts to teach him magic, since he would eventually grow up to be evil?
Answer: Dumbledore did not know when he first met the young Tom Riddle that he would one day become the evil wizard, Lord Voldemort. He even tells Harry this when they are discussing him. Riddle took the name of Voldemort when he began his rise to power some time after he left Hogwarts. Dumbledore always had suspicions about his behavior while he was a student and kept a close watch on him, but at that time he was unaware of who and what he would become.
Question: In the Ministry of Magic when they try to get to Umbridge's locket, how does she knows that it's Harry? Did she use some magic?
Answer: Umbridge did not know that it was Harry. During the interrogation scene when they are trying to retrieve the locket, Harry is still disguised as Albert Runcorn by the Polyjuice potion. The only thing that Umbridge noticed was that Harry suddenly produced his wand from his coat sleeve. This made Umbridge suspicious and she asked "Albert" what he was doing. That is when the polyjuice potion started to wear off and Harry was transforming back to himself, but he "stupified" Umbridge before she knew exactly what was happening.
Question: Why did Hermione clear her parents memory of her at the beginning?
Answer: To protect them from Voldemort. She knows that if he discovers anyone is helping Harry hunt the horcruxes, the Dark Lord will murder their families in retaliation. In the book, Hermione also sent them to Australia under a new identity, and Harry broke off his relationship with Ginny to protect her.
Question: I didn't get it, but who was the "ghost" deer that led Harry to the pond with the Griffindor sword in it? Or why did it lead him there?
Answer: It's not a ghost. It's a patronus, like the one Harry conjured in "The Prisoner of Azkaban," to save Sirius Black. Every wizard's patronus takes a different animal form. An as yet unknown ally (revealed in part 2, and the book) sent the doe patronus to lead Harry to where the Sword of Gryffindor was hidden.
Question: After Harry and Ron find the sword of Gryffindor, how do they find Hermoine again? The camp had enchantments and spells around it to keep them safe and Harry had to leave the protection set up around camp.
Answer: Because Harry already knew where the camp was. The protection spells they use (Harry is shown at one point casting them as well) seem to be sort of like the Secret Keeper spell. If you cast them or they are cast on you, it allows you to see through the spells. Also, don't forget that the deluminator led Ron right to the general vicinity of the camp and that the Snatcher team could smell Hermione's perfume through the spells earlier.
Question: How did Grindlewald know that Dumbledore was buried with the wand?
Answer: This is actually never explained in the movie. In the book, Voldemort located Grindelwald in Nurmengard prison so he could learn the whereabouts of the Elder Wand. Grindelwald lied to Voldemort about ever having possessed the Elder Wand, perhaps in a belated effort to protect Dumbledore, his former friend and foe. Voldemort read Grindelwald's mind using Legillimancy and learned that Dumbledore had captured the wand from Grindelwald after defeating him in their epic duel many years before. Voldemort murdered Grindelwald, then deduced that the Elder Wand must have been entombed with Dumbledore.
Question: In the scene where Ginny asks Harry to zip up her dress, George come into the kitchen in the middle of Harry and Ginny's kiss and says "Morning". What is that's sticking out of his ear hole/bandage?
Answer: It's his toothbrush. He's brushing his teeth when he comes into the room, and sticks it in his ear for effect.
