Chapter Three

"Grimmauld Place"

Few days after this, Harry and Hermione were transferred, with the usual escort, to the Headquarter of the Order of the Phoenix, in number 12 of Grimmauld Place, in London; at their arrival, they found Sirius waiting for them, and Hermione almost swooned; Harry caught her just before she fell on the ground.

They settled in the rooms that they used also the year before, and found Ron waiting for them.

"Harry!! Hermione!! What a pleasure seeing you!! How are you?" he asked

"We are ok, Ron.we are only a little tired."

"However, congratulations.I heard that finally you stopped being blind about your feelings." Harry and Hermione looked at each other smiling, then they asked: "And you? How it is with Lavender?"

"Well.can we speak about something else? I miss her too much." Ron replied, a little sad

"However, I imagined him, or Sirius is alive and is here?" Hermione asked

"No, you are right.he is alive.he is returned.but, why aren't you surprised, Harry?"

"Because I already knew this.the day of my birthday, I found him in my room.but I didn't say anything because I was afraid of having dreamed him." he added, answering Hermione's scolding look.

That evening, during the dinner, they celebrated the Sirius's return and the new couple, with Molly Weasley touched for the happiness.she considered Harry and Hermione as two other sons, and seeing them so happy was her dream.

The next day, they continued the war against the house started the previous year; Kreacher didn't clean anything, so they had to work very hard to make acceptable the house of the ancient lineage of the Blacks.

One day, however, even if all of them were used to his insulting mutterings, Kreacher went over the limit.he not only called Hermione mudblood, but when Harry scolded him, he insulted heavily also his parents, so Harry lost his control and stunned him, throwing his body with the old objects they wanted to eliminate.

This time Hermione didn't protest; after what he did the previous year, nobody respected him anymore, so he was mashed with the other rubbish. Life flowed happy at the number 12 of Grimmauld Place , until Sirius hadn't to leave for the Eastern countries, in a top secret mission for the Order, a very dangerous mission and a very long one.it would last some months. Harry felt a little empty that day, nevertheless the calming presence of Hermione always near him.

The next day their letter from Hogwarts arrived, and Harry was happy of having been chosen as prefect .even if he never admitted it, the previous year he was disappointed for not having been chosen. Obviously, the other Gryffindor sixth year prefect was Hermione, the most favourite for the Head Girl position, the next year.

A few days before their leaving for Hogwarts, all of them went to Diagon Alley to buy what they needed, and unfortunately they met the only student of Hogwarts that they never would want to see: Draco Malfoy.

Malfoy, after having seen Harry, attacked him behind his shoulders: "Crucio!" he yelled, but Harry, without turning himself, muttered: " Protego" and then he heard Malfoy shouting in pain, unable to defend himself from his own curse. Then Harry turned and said him, ironically: "You have taken your father's way, haven't you?"

"Don't name my father, Potter, or I'll kill you." Draco replied

"Do this, if you are so brave.we will see what you can do."

"Avada." he started, but Harry was quicker, and said: "Expelliarmus" , making him fell backward, and his wand fly in his hand; then, Harry threw it back to Malfoy, saying: "If you want to be a good Death Eater, you'll have to improve very much, Malfoy.", then he turned to Hermione, smirking, and entered the bookshop.

Malfoy stood up, and went away, fuming; Hermione said: "You was an irresponsible.what have you done if you couldn't disarm him?"

"Oh, don't worry.even a second year would be able to disarm him.he is so bad in duelling."

When they returned at home, that evening, they found Dumbledore waiting for them; he had dinner with them, then he wanted to speak to Harry alone.or, better, in presence of the other members of the Order, but not with the other boys.

"Harry, this is an important moment in your life", he said, "I designate you as extraordinary member of the Order of the Phoenix"

"Extraordinary member?" Harry repeated "And what this means? Would I take part to the meetings?"

"No, Harry.not at all, at least.only to the ones which will be related to the missions the Order will assign to you.that won't be very much.then, when you will have finished the school, you'll be an ordinary member as the others, and you'll be able to take part to all the meetings."

"So.I'll have missions to accomplish? But, if I'll be at Hogwarts." but Dumbledore interrupted him, saying: "Maybe you'll have missions, maybe.I hope you won't, however.and if you'll have one, we'll find a way to let you go to accomplish it." then he added: "Now, go to sleep, and not tell to anyone what I said to you.", but seeing his look, he softened, and said: "Ok.but only to her.", and smiled.

Harry went to bed without answering Ron's questions, saying that it had to remain a secret between Dumbledore and him, but the next days, as soon as he was alone with Hermione, he said it to her: "Missions? So young? But it won't be dangerous?" she asked, worried, but he replied: "Nothing can be more dangerous than duelling with Voldemort, I think" then he hugged her, and kissed her.
