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.
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?
Question: When Harry is brought into Malfoy Manor, Draco is told to confirm that it's really him. Even though Harry's face is jinxed, Draco knows that it's him, so why did he lie and say it wasn't?
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?
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.
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: 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?
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?
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?
Question: In the Malfoy Manor scene, Bellatrix tortures Hermione, but all we see is "mudblood" carved on her arm. Because of her loud screaming, it is assumed that Bellatrix did something more to torture her, did she?
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?
Question: At the end when Dobby is stabbed, Harry says he wants Hermione to get something from her bag and she doesn't do anything. Why would she not get anything from her bag. It's unlikely she wouldn't have her bag since she had it at the beginning of Part 2?
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?
