On Tuesday, breakfast went well and Harry went to his classroom. He walked in and saw a room full of students. Lily was sat in the middle of one side in the front with four other girls seated around her. Snape, Roman and a few others were seated as far away from the group as possible and some girls were in front. "Hello, seventh year Gryffindors and Slytherins, right?" A lot of people nodded. "Well," before Harry could go farther, the Marauders ran in.

"Sorry Professor." James apologized. "We had to see Professor McGonagall." He handed over a pass.

"It's alright boys. Just take your seats and we'll start." Harry said, shocked at being called 'Professor'. After they did, Harry went on, "As I was saying, I am Harry Patterson, you're new Defense Against the Dark Arts professor. Does anyone have any questions?" James' hand shot up. "Yes Mr. Potter, is it?"

"Yes Professor. Um, how old are you?" James asked.

"19." Harry answered. There were gasps. Lily raised her hand. "Yes Miss Evans?"

"Yes, sir. How did you become a teacher so young?" Lily asked.

Harry pushed down his emotions and answered, "Well, I have had a lot of experience with the dark arts, much against my wishes. And experience is more important than age." Lily nodded before Remus raised his hand. "Yes Mr?"

"Lupin, Professor. What are we learning this year?" Remus asked.

"Well, I was going to ask you that. What did you learn last year?" A Slytherin girl raised her hand. "Yes Miss?"

"Coffman, Professor. Clarissa Coffman. Our teacher last year didn't really teach much. We really just learned theory. And also, do you have a girlfriend?"

"Thank you Miss Coffman. Well then, we'll learn about dueling to start with. And yes, I do have a significant other." Harry said. Some of the girls deflated at this. Lily's hand went up. "Miss Evans?"

"Can you teach us about the unforgivables?" Lily asked meekly.

"What, no!"

"They're illegal!"

"Quiet!" Harry commanded. "Actually, I will. Dumbledore believes that you guys are ready to learn about them. I will not be teaching you to do them, but how to avoid them. However, not today. Today, we will be surveying how much you know. So, you will not be needing parchment. I'm going to call roll and then we'll get right into it. So, Otto Avery?

"Here!"

"Sirius Black?"

"Here."

Everytime Harry called a name, they said 'Here.' "Clarissa Coffman? Bartemius Crouch? Lily Evans? Alice Fortescue? Remus Lupin? Mary MacDonald? Walden Macnair? Roman Malfoy? Morgan Mulciber? Peter Pettigrew? James Potter? Evan Rosier? Florence Sanders? Severus Snape? Cynthia Watkins?"

"Here!"

"Great, so I just want to see how much you know. Some things, I will have you come and demonstrate. Some of them will be easy, so please bear with me. Mr. Pettigrew, please attempt to disarm me."

Peter got up and clearly casted, "Expelliarmus!" Harry's wand flew from his hand and Peter brought it back up to him.

"Very good Mr. Pettigrew. Now, Miss Coffman," Harry said looking at a female Slytherin named Clarissa, "what is a patronus?"

"Um, we haven't learned that," the honey-brown haired girl said.

"Well, then we'll learn it this year. So, instead Miss Coffman, can you tell me what spell you should use against a boggart?"

"Riddikulus. But that's not enough. You also have to think about something funny," she answered easily.

"Excellent. Mr. Snape, where can you most commonly find a kappa?

"Mongolia?" Snape said, unsurely.

"Actually, kappas are native to Japan." Lupin corrected.

"Correct Mr. Lupin. Miss Evans, please come up and cast a shield for me."

Lily walked up and clearly said, "Protego," and a shield appeared.

"Very good, now, Mr. Potter, attempt to stun Miss Evans." Harry requested. James smirked and cast a stunning charm which hit the shield and disappeared. His face fell. "Thank you. You may both take your seats." Harry went through the list he had for people and asked them to demonstrate or just answer a question for DADA. Very close to the end, Harry noticed something in Sirius' hand. He immediately recognized it. "Mr. Black, would you please put away your giggle bomb? Defense Against the Dark Arts is a serious subject." Sirius looked shocked and stowed it away. Harry checked the time. "Alright, well, that's it for today. For homework, I'd like you to make a list of all of the spells you know and how they can be used in defense. Because you know so many spells, you'll have two weeks to complete this assignment. You are dismissed. Oh, Mr. Potter and Mr. Black, please stay behind for a few moments." James and Sirius came to his desk. "Okay, look. I am perfectly fine with pranks," James' face lit up but immediately fell when Harry added, "performed at appropriate times. And the Start of Term feast is not an appropriate time."

"Yes, Professor Patterson," they both nodded and left. Harry went to Dumbledore's office.

"Hello, Harry." Dumbledore greeted.

"Hello, Albus," Harry nodded.

"Can I do something for you?"

"Yes. Well, I'm planning on teaching my sixth and seventh years about the unforgivables. Well, my teacher, aka my neighbor, taught us by casting it on us. Well, the Imperius anyway. It taught us how to throw it off. I just wanted to know if it was alright if I taught them that way."

"Yes. It will teach them to throw it off which is the best defense mechanism. Go ahead, but ask them if they're okay with it first."

"Of course I will. Well, I've got to go. I have 5th year Ravenclaws and Slytherins right now." Harry left.

On Friday, he had the 7th year Slytherin and Gryffindors again. "Hello class."

"Hello Professor Patterson," they greeted.

"Alright then, today we are going to be talking about the unforgivables. Mr. Snape, can you name one of them?"

"Um, the Imperius Curse?" Snape said.

"Correct. Can you tell me what it does?"

"It puts the victim under the caster's control." Snape said, earning 10 points.

Harry got out a spider. "Engorgio. Imperio!" Harry cast it and made the spider start ballet dancing on the desk. The class was laughing. "Stop! This may seem funny now, but it won't be if and when someone casts it on you and forces you to kill your family." Harry glared. They all stopped as Harry lifts the curse. "Mr. Stebbins? Can you name another?"

"The Cruciatus Curse. It inflicts terrible pain upon the victim."

"Correct, 10 points to Gryffindor." Harry turned to the spider, "Crucio!" The spider started rolling in pain. Harry lifted the spell. "And, Miss Evans, what's the last one?"

"Avada Kedavra, the killing curse. There is no escaping it." Clarissa answered.

"Another 10 points to Slytherin." Harry turned to the spider and thought about how scared they make Ron and said, "Avada Kedavra!" The spider fell off the table immediately. "Next class, we will be working on resisting the imperius curse."

"How?" Lily raised her hand.

"I will be putting you all under the curse and you will be working on throwing it off."

"You can't, it's illegal!" Walden Macnair raised his hand.

"I will be. Because, why, Mr. Macnair, is it illegal?"

"Because whoever is placed under it will do whatever the caster wants."

"Yes. And you all need to know how to throw it off. How else can you keep yourself from falling under it? When I was learning about them, my teacher put it on us and I threw it off. Death eaters tried to put me under them, but it never worked. That's what I want for you too. I want you to be able to resist someone else's control. But, for the cruciatus curse, we will only be studying how to throw it off. I'm not interested in subjecting anyone to that pain." Harry said. Then he dismissed them.

Sirius walked up to him and said, "Professor Patterson?"

"Yes, Mr. Black?" Harry asked, looking up from the pile of papers he was going through.

"I just wanted to say that I think that casting the spell on us to get us to resist it is a really good idea." Sirius said.

"Thank you Mr. Black." Harry nodded and Sirius left.

Harry's next step was to go to McGonagall. At dinner that night, she sat down next to him sighing. "I swear those boys will be the death of me. Half of the detentions we have given out has been to those four in the past seven years."

Harry thought about Fred and George. "Well, there were two pranksters when I went to school. They were named Falcon and Gavin. They wanted to show that authority doesn't mean you're better than everyone which was a good thing to show one or two of their brothers, by the way. But, that wasn't the only reason. They also just wanted to get a laugh out of everyone. I figure they try harder in these years because of the war."

"I never really thought about it that way. I always thought they just wanted to break rules and humiliate Mr. Snape," Minerva admitted.

Harry laughed, "Well, they seem to be doing an exceptional job with humiliating Mr. Snape, but i doubt this is their only only motivation. They are intelligent young men."

"Still though, I'm glad this is their last year here. Noble mission or not, they make us teachers very tired."

"I can see that."

"Oh, they have detention tomorrow night for dueling Mr. Snape. Mr. Snape will be with me, but is there any chance you can take the four?" McGonagall asked clearly not wanting to deal with all four.

Harry laughed a bit. He had never seen McGonagall like that. "Of course Minerva." She brightened.

"Thank you."
