Draco tries to spend time in his cell ... but in another cell ... Lurtz performs a spell, which turns him into an Urku Hai! ... a kind of orc, Draco realized this, Lurtz breaks the bars and escapes ... two Hogwarts guards enter to stop him ... but Lurtz is so strong, that he strangles both in a single attempt ... then Lurtz frees the other prisoners. More soldiers and prefects of Hogwarts are alerted.

Prefect of Hogwarts: "To the dungeons!"

Then Lurtz arrives at Draco's cell ... there they face each other, Lurtz decides not to release him and prepares to leave ... but ...

Draco Malfoy: "I suggest the stairs to the left".

Lurtz, seeing that there are many guards and prisoners fighting in front of him, takes Draco's suggestion.

Harry, Hermione and McGonagall also notice.

Minerva McGonagall: "That came from the cells."

Harry Potter: "Draco."

Minerva McGonagall: "Go, I'll take care of her."

Harry takes his broom and wand and flies to the dungeons ... where Neville and Ron are already fighting the prisoners.

Ron Weasley: "You realize ... it's as if they resent his imprisonment".

Neville Longbottom: "Too bad you can not please everyone."

Draco just watches the battle, as he reads. Then Harry arrives at the place.

Harry Potter: "If they return to their hearts, I will forget what happened ... I promise."

But a prisoner hits him in the face.

Harry Potter: "Now, I change my mind."

Harry starts attacking them and fighting too.

Albus directs another troop.

Albus Dumbledore: "Send our best shield, protect the dungeons."

Then McGonagall and Hermione meet Dumbledore.

Minerva McGonagall: "Dumbledore."

Albus Dumbledore: "McGonagall ... You guys go! ... it's a little brawl, everything in order".

Minerva McGonagall: "You do not have to lie to me so that it's okay, director."

Then Ginny goes to fight, but on the way she meets Hermione, both exchange looks.

Albus Dumbledore: "Take her to your rooms, there if it's safe".

Minerva McGonagall: "Take care of yourself."

Albus Dumbledore: "Despite all the battles I have fought, my most faithful companion is still anguished by me."

Minerva McGonagall: "How bad that all this time I've only been your partner." Sarcastic tone.

McGonagall arms herself with her wand.

Minerva McGonagall: "Now Hermione, do everything that I order, without questioning once."

Hermione Granger: "Sure, I'm good at obeying."

At the entrance of Hogwarts ... Hagrid detects that something is approaching ... it's a black chariot! Hagrid quickly releases the Hippogriff, mounts it and flies to the chariot ... when it approaches it jumps on it and beheads the rider ... this causes the chariot to collapse before it enters Hogwarts ... but it turns around and he sees a bigger float ... besides, this was a distraction, because more floats manage to enter ... the riders are Dementors. More Hogwarts soldiers fly off on their broom to counterattack the floats. Hagrid meets with other Hogwarts masters to activate the Maximum Protective Charm, which creates a magical barrier to prevent more floats from entering Hogwarts. Inside the school, Lurtz massacres anyone who is in his way. But a carriage manages to cross the roof of Hogwarts and arrives at the The Great Hall ... Harry, Neville, Ron and even, Draco realize it. The soldiers and prefects of Hogwarts prepare for the attack ... the Dementors leave the chariot and a battle begins ... it is a very close battle, but the Dementors fight dirty ... besides, they open the way for their leader: Igor . Igor walks very intimidatingly, incidentally, destroys the Dumbledore Eagle Stall. Draco only observes the chaos, Dumbledore arrives with the reinforcements and in front of him, sees a Dementor.

Albus Dumbledore: "Avada Kedavra!"

And he kills him, Dumbledore sees many dead prefects and soldiers of Hogwarts, he knows what's going on.

Albus Dumbledore: "McGonagall, oh no."

Igor enters the room where McGonagall and Hermione are ... Hermione protects herself and McGonagall confronts Igor.

Minerva McGonagall: "Detend now, unhappy ... and we may forgive you for life".

Igor Karkarov: "I've survived more than you can imagine."

Minerva McGonagall: "Who are you?"

Igor Karkarov: "Igor ... Karkarov! ... and I have come for what belongs to me".

Then he fixes his attention on Hermione ... but McGonagall brushes his face with a dagger. This makes Igor angry and they start to fight with swords ... McGonagall dominates Igor, manages to put the dagger in Igor's neck threatening him ... but ... the fearsome Lurtz appears and hold her neck. Igor approaches Hermione.

Igor Karkarov: "You have something that is mine, girl, give it back to me".

Then Igor is going to touch Hermione ... but it was only an illusion, McGonogall did it. Igor is infuriated by this.

Igor Karkarov: "Damn witch!"

McGonagall grimaces.

Igor Karkarov: "She ... where is she?"

Minerva McGonagall: "I'll never tell you."

Igor becomes even more infuriated.

Igor Karkarov: "You do not have to tell me."

Lurtz sticks an arrow into McGonagall's back! ... Harry quickly appears.

Harry Potter: "Fire!"

Harry burns the upper part of the left side of Igor's face ... but Lurtz quickly takes Igor and they throw themselves through a balcony of the castle ... falling in a flying chariot and then disappearing and all chariots ... Harry only sees them go. Dumbledore enters the room ... Harry turns around and both Dumbledore and Harry are baffled ... seeing McGonagall lying on the ground, dead ... Hermione comes out from where she was hiding. Everyone is stunned, Harry can not believe it, Dumbledore hugs McGongall once more ... Hermione laments everything that happened.
