Part 2 of "The Deathly Hallows: Part 2" Quiz

Answer: in the Room of Requirement

Luna suggests that, since no one alive has seen the diadem, Harry should talk to the Grey Lady, the ghost who was Rowena Ravenclaw's daughter in life. Her name is Helena and her mother's diadem is a touchy subject because she remembers when Voldemort defiled it with dark magic. Harry convinces her that he seeks only to destroy it and she tells him where it is, in riddle form. Harry quickly solves the riddle and heads to the Room of Requirement to find it.
Helena Ravenclaw is played by Kelly Macdonald.

Answer: Draco Malfoy and friends

Draco swoops into the castle and grabs his friends Goyle and Zabini. They follow Harry into the Room of Requirement. They probably do not know that Harry is seeking another Horcrux, and are likely just seeking to get rid of Harry. Hermione and Ron also join Harry around this time and the fight steps up a notch. Harry is able to retrieve the diadem from atop a high stack of junk, where it went flying during the fight.
Draco Malfoy is played by Tom Felton, Goyle is played by Josh Herdman and Blaise Zabini is played by Louis Cordice.

Answer: on broomsticks

As the flames engulf more and more of the objects stored in the Room of Requirement, Harry, Ron and Hermione find that there's nowhere left to run. Malfoy, Goyle and Zabini have tried to climb up to avoid the flames, but Goyle falls and is immediately engulfed in the fire. Harry finds three brooms and they manage to fly above the flames, with Harry insisting that they go back and rescue Malfoy and Zabini.

They make good their escape above the flames, with a little help from Hermione's wand.

Answer: Lord Voldemort

Voldemort is not happy with the way the Elder Wand works for him. He feels that the wand does not give him its full allegiance since he did not kill the wand's previous owner. He believes that since Snape killed Dumbledore, the wand truly belongs to Snape. He therefore summons Snape to the boathouse and kills him, in order to win the wand's allegiance. He expresses very little regret in doing this, although he tells Snape that he has been a good and loyal servant.
Severus Snape is played by Alan Rickman.

Answer: Harry Potter

The wand's owner does not have to be killed for the wand to switch allegiance, only defeated. In "Harry Potter and the Half-Blood Prince", Draco disarmed Dumbledore in the tower, but was unable to kill him. So at that point the wand belonged to Draco, not Snape. During their escape at Malfoy Manor, Harry disarmed Draco and took his wand. Even though this was not the Elder Wand, the fact that Harry had defeated Draco and his wand had switched allegiance (as indicated by Ollivander) is enough for the Elder Wand, which also switches its allegiance to Harry long before Harry ever touches it.

Answer: Harry is also a Horcrux.

While in Bellatrix's vault and in the Room of Requirement, Harry can hear the Horcruxes talking to him. After he takes Snape's dying tear and looks at it in the Pensieve, reviewing Snape's memories, he understands why. When Voldemort tried to kill Harry, as a baby, the curse rebounded on him.

A piece of Voldemort's soul broke off and attached itself to Harry, making Harry the Horcrux that Voldemort wasn't even aware that he had created. This was the reason Harry could feel Voldemort's emotions and read his thoughts, and the reason that he had a connection with the other Horcruxes.

The Horcrux in Harry must be destroyed before Voledmort can be killed.

Answer: Lily and James Potter, Sirius Black and Remus Lupin

Harry feels comforted by these lost loved ones, who promise to stay with him until the end. Harry asks Sirius, his godfather, if dying hurts and Sirius replies that it's quicker than falling asleep. Lupin, Harry's former teacher and friend, does not regret his death and tells Harry that someday his son will know how brave his father was.
Although Harry was only one when his parents died, Lily and James have appeared to him before, helping him escape from Voldemort when Voldemort first regained his human form.
Sirius Black is played by Gary Oldman, Lupin is played by David Thewlis, Lily Potter is played by Geraldine Somerville and James Potter is played by Adrian Rawlins.

Answer: Rubeus Hagrid

Voldemort has issued a challenge to Harry, promising to leave his friends alone if Harry comes to him in the Forbidden Forest. Knowing, from Snape's memories in the Pensieve, that he must die, Harry accepts the challenge. When he first walks into the clearing, the Death Eaters have Hagrid, Harry's friend and Hogwarts professor, in chains. Being part giant, it's taking a lot of chains and a lot of Death Eaters to keep Hagrid contained. Hagrid yells 'No Harry!', quite upset that Harry has come to face Voldemort.
Hagrid is played by Robbie Coltrane.

Answer: Narcissa Malfoy

After Voldemort hits an unarmed Harry with a killing curse, we find Harry in a white room, probably King's Cross Station, discussing what has happened, with Professor Dumbledore. Dumbledore makes it clear that now that Voldemort has killed the piece of soul that has been residing in Harry for 16 years, Harry has choices about what happens next. Harry chooses to go back and stays lying on the forest floor, pretending to be dead. As he staggers to his feet, Voldemort asks if Harry is dead. Narcissa Malfoy, Draco's mother, checks. As she bends low she whispers to Harry, asking if Draco is still alive. Harry nods very slightly, so Narcissa announces that Harry is dead.
Harry continues to play dead as, still bound, Hagrid carries him to Hogwarts at Voldemort's command.
Narcissa is played by Helen McCrory.

Answer: It appears inside the Sorting Hat.

The morning after the battle, a limping Neville picks up the Sorting Hat from among the rubble and brushes it off. When Voldemort appears, claiming victory because Harry is dead and demanding allegiance, Neville makes a speech about fighting on without Harry. Harry picks this time to reveal that he is still alive and the fight begins anew. Ron and Hermione try, unsuccessfully, to kill Nagini, the last remaining Horcrux, but Neville saves the day.

He pulls the sword out of the Sorting hat (as Harry once did in "The Chamber of Secrets") and slices off Nagini's head, leaving Voldemort, fighting with a wand that owes allegiance to Harry, in a very vulnerable position.
