CHAPTER 4 -The First Day of Classes…

Harry woke the next morning, awaiting the first DADA class he would teach. Luckily it was to be the Gryffindor and Ravenclaw first years.

Ron and Harry soon joined Ginny and Hermione in the Great Hall for breakfast.

"What no big 'Good morning' kiss for you two?" Ron asked as he noticed how they greeted each other.

"We broke up." Both Ginny had Harry and large smiles on their faces, which completely confused Ron and Hermione.

"Harry! I thought…. You promised me that would never happen! I thought you were going to ask her…" Ron spluttered.

"Ron, It's not forever, just for the next 8 weeks. You'll see why after lunch."

The teachers came around with time tables. Harry was given his teaching time table.

"What do you have Harry?" Ginny asked, already knowing the answer.

"Defense. What about you guys?"

"I have Potions." Ginny said.

"Ron and I have Transfiguration." Hermione said.

"Ugh! I gotta go. I'll see you guys later." Harry got up and hurried off to his classroom. Placed on his desk was a lesson plan. He was teach the first years how to disarm each other.

As the first years filled in, Harry had a hard time controlling his nerves. He was in his office, pacing. At last, he couldn't put it off any longer. He opened the door, and made his way to stand in front of the class.

"Good morning. As you all know I'm Harry Potter. I'm you new Defense Against the Dark arts teacher for the next 8 weeks. At which time, Professor Stookê will take over. Today we will be learning the disarming charm.

"Harry paused and a young Gryffindor put her hand up.

"Uh, Professor?"

"Yes, Uh, your name?"

"Holling, Samantha Holling. Is it true you defeated the Dark Lord?"

"Uh," Harry blushed, "Yes, I did. In fact, I attacked him many times with the spell I am about to teach you. Every one pick a partner. Now, the technique is: Flick your wand and say expelliarmus!" Harry watched carefully as several students went flying. However he saw one student, Dorkus Mulltifo from Ravenclaw managed it first try.

After many classes, Harry was worn out, and really just wanted to go to bed. However, his last, if not most important class of the day, were lined up outside. Harry cast a spell and door flew open. Students poured in. This included Ron, Hermione and Ginny. Hermione immediately sat down and opened her book, wondering who the replacement was for DADA.

Suddenly, Harry appeared right in front of the class.

"Good afternoon, as you all know, I'm Harry Potter, and I'm your new Defense Against the Dark Arts teacher. Well, for the next 8 weeks any way." Ginny smiled proudly at Harry. Hermione's hand shot up.

"Yes Miss Granger?" Harry said with a hint of smile, trying not to giggle as he said that.

"What are we going to be learning today?"

"Well, this is where you and Mr. Weasley come in. I would like you to come up here, and tell the class of your experiences with Dark Magic." As they approached him, he whispered, "Don't mention Horcruxes…"

"Ah, well, Last year, Ron and I joined Harry, in a fight against the darkest wizard of all time. Unfortunately, it was not easy or fun. It was tiring and isolating. We were forced to hide out in forests and bushes. This quest also caused as to begin to bicker amongst ourselves. And if we hadn't had sorted it out, we all wouldn't be here now." Hermione began.

"Dark magic always leaves traces, which made it slightly easier to find him; however, it still took us along time, as we had no idea where to start. It was hard, as we all had family and friends we had to leave behind. I spent hours listening to the radio, waiting to hear bad news. Of course, it was all bad news, people disappearing, and lying dead somewhere. But I was hoping never to hear my family's names." Ron said.

"Of course there were people who stayed back at Hogwarts, who helped a great deal. Some of them have left now, but one particular young lady is still here, Miss Weasley, could you come up and tell the class of exactly what you were doing while everyone else was obliviously accepting punishment?" Harry asked.

"Very well. Last year, Neville Longbottom and I got into several mishaps as plan after plan failed to work. We didn't know exactly what Harry, Ron and Hermione were up to, but we did know this- He needed the Sword of Godric Gryffindor. It was kept in Snape's office. Time after time, we tried to steal and it, and every time we failed. Everyone was getting weaker, and we needed reinforcements. Dumbledore's Army, which was established by Harry, when we were in fourth year, were all there to give us a hand. The members often refused the requests of the Carrows and we were brutally punished. Some caved and did what they were told, but others, stayed strong, and in the end, assisted Harry in his fight against Voldemort." As Ginny said this, many people gasped. Even now the Dark Lord had gone, people were terrified to say or hear is name.

"Thank you. Now, today's lesson may have been as exciting as you would have liked, but for you, I feel it was important for you to hear first-hand accounts of what Dark Magic is really like. For homework this week, I would like you write the three most useful spells, in your opinion, that you would use against the Dark Lord. These spell must be ones you know how to perform. This is due next lesson." Harry concluded. There were groans from many. Everyone jumped to leave as he packed up his books. However, Ron, Hermione and Ginny lagged behind.

"Harry! However did you become teacher?" Hermione asked.

"Well, McGonagall asked me. They needed someone to DADA for the next eight weeks, so I'm it."

"Right, and the reason you broke up with my sister was…?" Ron was puzzled.

"Oh you idiot! Harry and I couldn't be together if he's the teacher. He didn't want to take the post at first, but I forced him to. He's the best teacher, for this subject we're likely to get." Ginny butted in.

"Right! Oh well…" Ron spluttered.

"So, Harry will there be an exam at the end?" Hermione asked.

"I'm not supposed tell you that Hermione. But yes there will be, but I'm not telling you anything else. And the week before the exams, I'm not even aloud to be seen with any of you. Which sucks…" Harry said.

"It's ok Harry, we understand. See you tonight at dinner." Hermione said as they left the room.
