"The Order of the Phoenix" - Part 2 Quiz

Answer: Kreacher

Having served a household of dark wizards for most of his life, Kreacher is appalled at the Order using his mistress' house as a headquarters. He is constantly muttering insults under his breath about the Mudblood and Blood Traitors around him, and is seen talking to his mistress' portrait.

In the book Kreacher plays a role in the trap that lures Harry to the Ministry of Magic where the Death Eaters are waiting for him, but this is not included in the movie.

Answer: Cedric Diggory

Although we do get a couple of glimpses at this picture, it's best seen when Harry and Cho Chang are talking after practice one night. Cho, who went out with Cedric before he died, wonders if Cedric would have had a better chance had he known all the spells they were practicing. Harry assures Cho that Cedric did know all this stuff and was, in fact, really good. Then the mistletoe appears and they kiss.
Cho is played by Katie Leung.

Answer: a rabbit

Luna's silvery rabbit is seen hopping around the Room of Requirement. Hermione produces the otter, and Harry produces the stag (as his father before him). The doe is a Patronus we learn about in the seventh book, but I won't reveal who produces it, in case I spoil anything for you!
If you have read the book you will know that her Patronus is actually a hare, which is closely related to a rabbit.

Answer: Arthur Weasley's

There is a weapon, of sorts, that Voldemort wishes to get his hands on and the members of the Order are taking turns guarding it. On one of Arthur Weasley's nights to guard, Voldemort sends his snake, Nagini, down to check things out. Voldemort is able to see through Nagini's eyes, and through his mind connection with Voldemort, Harry is also able to see what the snake sees. Harry sees the snake strike Arthur and is able to alert Dumbledore in time to get help to Arthur in time.

Answer: Severus Snape

Afraid that Voldemort will be able to read Harry's mind as clearly as Harry reads his, Dumbledore wishes to teach Harry how make his thoughts inaccessible to the Dark Lord. Snape has a real gift for this ability, and so is chosen to instruct Harry. The natural animosity between these two makes for a difficult lesson. Snape invades Harry's mind and makes nasty comments about what he sees in Harry's memories.

At one point Harry is able to turn the tables and take one of Snape's more unpleasant memories from him.

This ends the lesson rather quickly.

Answer: Cho Chang

Umbridge is determined to stop the group and punish its members and towards that end she uses Veritaserum (truth potion) on Cho. After Cho tells her about the room, Umbridge breaks down the wall and captures the members of Dumbledore's Army in action. Harry, with his crush on Cho, is devastated to see her standing with Umbridge when the wall is broken down.

It isn't until later in the movie that Harry finds out why Cho did this. Umbridge asks Snape for more Veritaserum, to use on Harry, Ron and Hermione. Snape answers that the last of his supplies were used on Miss Chang.

Answer: his half brother

When Hagrid first returns, he tells Harry, Ron and Hermione about his mission to recruit the giants and how it wasn't terribly successful. It isn't until after Dumbledore leaves Hogwarts and Umbridge is named Headmistress that he takes them into the forest to introduce them to his half brother, a full grown giant.

He is concerned that with Dumbledore gone he will be next and wants Ron, Hermione and Harry to look after his brother should that happen.

Answer: O.W.L.s

O.W.L.s, or Ordinary Wizarding Levels are important exams that are sat at the end of fifth year. How a student scores on these exams determines what advanced level classes they can take, which affects their career paths. Umbridge's theory only approach to teaching Defense Against the Dark Arts puts the students at risk for passing that O.W.L. which is why Dumbledore's Army is formed. Harry wants to become an Auror, and scoring well in that class is an essential prerequisite for that profession.

Answer: They lead her to the Forbidden Forest and the Centaurs take her.

Umbridge wants them to reveal where Dumbledore is hiding, but has no more Veritaserum to use. She is going to use the Cruciatus curse on them, to make them talk, when Hermione starts talking about Dumbledore's secret weapon. They lead Umbridge into the Forbidden Forest, in search of this weapon. Hagrid's giant brother has already riled the Centaurs and when Umbridge starts calling the Centaurs half-breeds, they carry her off, deeper into the forest. Harry, Ron and Hermione met up with Luna, Neville and Ginny and they ride Thestrals into London, in response to Harry's vision from Voldemort.

Answer: The Department of Mysteries

The item sought by Voldemort is stored in the Department of Mysteries, which is announced when they get off of the elevator. In the movie the Department only seems to contain one room, full of prophecies, and the stone archway through which the voices of those who have pased over can be heard. In the book there are several room, each containing things more bizarre than the room before.
The prophecy, made by Sybil Trelawney to Albus Dumbledore, concerns Harry, the one with the power to vanquish the Dark Lord. Since the prophecy could only be taken by the one whom it was about, Voldemort needed Harry to retrieve it for him. So he sent Harry a vision of Sirius being tortured, relying on Harry to respond, which he did.
After Harry picked up the prophecy, the Death Eaters arrived and the battle was on.
Voldemort never got his prophecy afterall, since Lucius Malfoy dropped and broke it.
