Question: When Umbridge has Harry, his friends and the Slytherin students in her office, she asks Harry if he was going to warn Dumbledore. When he says he wasn't, she responds by slapping him in the face. In the background, Draco has a look of shock on his face. Considering the fact that he hates Harry, why would he react this way?
Question: Since Harry told Cho that Cedric knew "this stuff", and Cedric was a sixth or seventh year student when he died, I guess older students are taught the Patronus Charm in school. Why, then, does the Ministry of Magic bother using Dementors when so many magical people have learned how to escape them?
Question: The prophecy says that Voldemort and Harry can't both survive, so why have they both been alive since the last movie and Voldemort doesn't die for another two movies?
Question: I just read the third book, and in it, Lupin said that the Dementors take a wizard's powers away while he/she is in Azkaban. Did Bellatrix and her fellow escapees have them restored by Voldemort or something?
Question: Why was Voldemort at a train station in one of Harry's visions? I am wondering why he would let himself be seen by several people. The news that he has returned would get around to Cornelius Fudge.
Question: Why did Harry and Ron get into so much trouble for using the flying car in "Chamber of Secrets", but in this movie/book, the Order of the Phoenix members openly fly on broomsticks?
