Question: When Harry and Hermione are rescuing Sirius, Hermione blasts open the door using a different spell than the one she used in The Philosopher's Stone to open the door to where Fluffy was. I can understand that the reason the spell would be stronger on Sirius's cell is so he can't escape and it's more secure. But the Philosopher's Stone had to be secured well, so why was the lock so easy to unlock?
Answer: It's never stated that one spell is stronger than the other. There may be different spells that achieve similar results, and Hermione simply chose one over the other. Therefore, it should not be assumed that one lock was easier to open than the other. Also, the "bombarda" spell was never mentioned in the books. It was invented by the filmmakers for the movie, probably because it sounded stronger and was more descriptive (as in to bombard).
Question: This is a 2 part question. 1. When the Dementors first appear on the train, why does frost cover the windows and the train become so could? 2. If the Dementors were sent to recover Sirius Black, why would they be on a train full of Hogwarts students?
New this week Answer: The frost appearing whenever the Dementors are nearby never happened in the books. It was solely a creation for the movie as a device to foreshadow their oncoming and ominous presence. This same freezing over plays a part later in the movie when Harry saves Sirius from the Dementors by the lake. The audience already knows it signals something bad is about to happen. Regarding the second part of your question, When Sirius Black escaped from Azkaban, it was known that he wanted to kill someone who was at Hogwarts. Because he was convicted as Voldemort's accomplice in Lily and James Potters' murders, it was assumed he was on his way to kill Harry. The Dementors are on the Hogwarts express, and later at the school, to protect Harry as well as hunt for Sirius. However, the Dementors have overstepped their purpose and become a threat to Harry, who has a particularly strong reaction whenever they approach him.
Question: When the Fat Lady portrait is found shredded (by Sirius) there is a baby crying. In the scene you can see a youngish girl holding a crying baby, off to the left in the screen. Why is there a baby at Hogwarts?
Answer: It is not an actual mother and baby. Like the Fat Lady, they are one of the many moving portraits hanging on Hogwarts' walls. Look a little closer and you'll see the picture frame surrounding them.
Question: Do some Hogwarts students arrive at school before others? I ask because of the choir singing in this movie, on the first day of the term. Wouldn't they have needed at least a day to practice the song?
Answer: All the students arrive on the train, but it is feasible they took part or all of the afternoon on the train to practise. They also could have met a few times over the summer.
Question: In the answer to another question here, it says that Dumbledore wanted the other teachers to keep Remus' werewolf condition a secret. Wouldn't Severus get into trouble for trying to teach the Defense Against Dark Arts class about werewolves?
Answer: Snape is clever enough to know how to circumvent getting into any serious trouble, though Dumbledore probably was displeased by what he did. Werewolves were a standard part of the Defense Against the Dark Arts curriculum, though, when subbing for Lupin, he decided to cover the subject weeks ahead of schedule in the hopes a student would recognize that Lupin was a werewolf without it being him directly giving away the secret. Of course, it was Hermione who figured it out, though she kept that knowledge to herself until it became necessary to reveal it.
Question: Towards the end of the third film, when Harry and Hermione are successful in saving Sirius black, why does Dumbledore act like he doesn't know anything when they see him outside the hospital room door?
Answer: He does not want it known that he was the one who planned for Harry and Hermione to rescue Sirius, who is still a wanted felon at this point. It would cause Dumbledore serious legal problems (he would be arrested and sent to Azkaban) if was he suspected of aiding Sirius' escape. That is why he acts like he does not know what happened.
Question: Before Harry gets on the bus for stranded witches/wizards, Sirius appears in dog form and growls at him. Why is Sirius behaving aggressively toward his godson?
Answer: Sirius wasn't being aggressive toward Harry. In the book, Harry merely saw a hulking shape and a pair of eyes in the bushes watching him, but there was no growling. The way it's shown in the movie was played up to make it appear that there is some imminent threat to Harry. The filmmakers were apparently attempting to foreshadow the coming danger and to keep the audience in suspense about Sirius' identity and true intentions.
Question: Did Harry simply get away with attacking Professor Snape? It happened before the moment that he and Hermione would time-travel back to, so it wasn't erased.
Answer: Harry was acting to save Sirius, who Snape was intending to turn over to the Dementors so his soul could be sucked out. Due to the unusual circumstances, Dumbledore would not have allowed Harry to be punished for protecting his godfather and uncovering the truth that proved his innocence. Dumbledore also knew Snape had acted inappropriately due to his personal hatred of Sirius. In the book, Snape was simultaneously jinxed by Harry, Ron, and Hermione. Snape later claimed they were not responsible for their own actions and were coerced.
Question: What song/music is Lupin playing in the first Boggart scene?
Answer: The song during the boggart scene is called Hot Liquorice.
Question: Except for Remus Lupin in this movie, it seems as though the Hogwarts teachers do not use the Hogwarts Express. How do they arrive at and leave the school?
Answer: There's a variety of ways that wizards can travel including magical vehicles (like the motorcycle that Hagrid drove), broomsticks, port keys, riding flying animals (like a hippogriff or the threstrals) and apparating from one location to another. They could also use floo powder if their fireplace was connected to the floo network like Umbridge had in her office. The other teachers can certainly travel on the Hogwarts Express, and some probably do but just aren't shown. In the book, "Half-Blood Prince", Professor Slughorn rode the train and some teachers live at the school year round.
Question: How did Harry send his own patronum at the lake without knowing it ?
Answer: After the first time Harry saw it, as he was being attacked by the dementors, he had convinced himself that it was sent by his (dead) father, who he believed had somehow been resurrected. When he goes back in time three hours, and watches the other Harry across the lake, he realizes that it was he who cast the earlier patronus, not his father. That is when he casts it again.
Question: Does Professor Snape know about Hermione's time-turner necklace? He doesn't seem to care that she suddenly appears in the Defense Against Dark Arts class out of nowhere, especially after class started. (I haven't read the third book yet, so I apologize if this is answered there).
Answer: Snape, and all the Hogwarts instructors know that Hermione is using the time-turner to take extra classes. A time-turner can only be used under very strict conditions and must be approved by the Ministry of Magic. That is why Snape does not punish Hermione for arriving after class has started. If she was merely being late, he would have been angry and deducted house points from Gryffindor.
Question: After Harry wakes up in the hospital wing, Hermione was telling Harry that Snape said an incredibly powerful wizard could have produced the patronus that saved Harry and Sirius Black's life. Snape knew how powerful James and Lily were as witches/wizards so did he make the connection? Does Snape know that Harry made the patronus? even though Snape already knows Harry is destined to destroy Voldemort.
Answer: Snape woke up after the Patronus was conjured, only seeing the Dementors flying away from the scene. Harry nor Snape did not know who made the Patronus (it was Harry, even though Harry thought it was his dad) And at this point, Snape does not know that Harry is destined to destroy Voldemort. He did not hear the end of the prophecy and Dumbledore had not confided such information to Snape as of the end of the third book.
Question: Why did Professor Snape insist on teaching Professor Lupin's class about werewolves (when he takes over the class)? If he or any other staff members suspected Lupin of being one, it seems that they wouldn't want to cause any panic or distraction among the students.
Answer: Severus Snape hates Remus Lupin because he was best friends with Sirius Black and James Potter, who used to torment Snape when they were all students at Hogwarts together. Snape is teaching the class about werewolves in the hope that one or more of the students will recognize Lupin for what he is, tell their parents about it, and then Lupin will be fired from his position. Snape takes this roundabout course of action most likely because all the faculty had promised Dumbledore to keep Lupin's nature a secret from the student body for this very reason.
Question: In the scene where Harry is playing Quidditch, he is followed by the dementors. Why isn't he flying back to the Quidditch game at the ground? There would've been enough people who could have helped him. What happened to the dementors after, did they hurt anybody else?
Answer: Hermione visits Harry while he's recovering and explains that the incident never should have happened and Dumbledore was so furious over it that he banished the dementors way back behind the ground's perimeter. When Harry encounters the dementors they begin sucking out his soul, sort of. His face is shown almost like smoke being drawn to them and they, in turn, appear to be "sucking" the face smoke stuff into their "mouths." it looks horrific and I'm surprised anybody would ever wonder why he didn't retreat. He didn't retreat because he couldn't. It's that simple - he wasn't able to.
Question: After turning into a werewolf, what is it Lupin mutters as Hermione is walking over to him? It's very difficult to understand, but it sounds like words. Not just whining. (I don't know if it is in the theatrical version. I am noticing it on the DVD copy).
Answer: He's not saying anything, it's just unintelligible whimpering. It gives the impression that Hermione is able to communicate with him, but once Lupin has transformed into a werewolf, he has no human consciousness.
Question: WWhen the boggart changes into something in the classroom scene, can everybody see it then? Are all people seeing the same, or do they see the object that frightens them the most?
Answer: The all see it the same; it turns into the thing that most frightens whoever has the boggart's attention at the time.
Question: When Fred and George were in possession of the Marauders Map, before giving it to Harry, how come they never wondered why Ron was always hanging around with a person called Peter Pettigrew? He shows up on the Map even whilst disguised as Scabbers, as we know from when Harry spots him.
Answer: Fred and George used the map to aid them in their mischievous activities at Hogwarts, and probably had little interest in what their little brother was doing or who he might be with at any given time.
Question: Why did Harry and Hermione fear the werewolf if they knew that Hermione would save them?
Answer: They didn't know. Hermione's call distracted the werewolf when they first saw him, true enough, but that was before they had time jumped, so the Harry and Hermione that were scared of the werewolf were unaware that their future selves were around to save them.
Question: Can somebody please tell me why there was a dog in the sky? I know it had something to do with the 'Grim'.
Answer: That's it exactly. It's a bit of in-world foreshadowing. Divination isn't complete malarkey, as McGonagall makes it out to be; Trelawney just doesn't have a knack for it aside from Prophecy which she herself is ignorant of actually possessing. Whatever magic controls such things as tea leaves and the like caused the clouds to form into the shape of a Grim. Harry just misunderstood the warning.
