AN: Heyo, Tekky Here, reminding you all that I do not own Harry Potter, Yu-Gi-Oh or Marvel, I do however own Charlotte Anderson, and most of hte OC Decks used in this Story, Tek Out.


(Outside the Defence Classroom)

Harry and Charlotte stood outside the Classroom listening to the ruckus inside and waiting for Snape. Snape walked round the corner and up the steps and Harry nodded to him "Come on in Professor Snape" Snape blinked but nodded "Thank you, Professor Potter" Harry nodded and the three walked into the classroom, silence awaited them.

(Inside the Defence Classroom)

Harry walked up to the Teacher's Deck and Charlotte sat down in his old seat, he looked over the Class and smirked as Snape stood in the dark corner "Settle Down, now I have a few announcements to make, first off, Hi, I'm Professor Potter, but as you are all my age, Hadrian is fine, now I'm not going to do a Lockhart or a Quirrell and not teach you anything, and I don't care what house you are from, I will treat you all fairly, now let's start with some basic questions".

He pointed at Draco "Name me three Dark Curses, set by the Ministry and what they do" Draco nodded "Coquite Sanguis, or the Blood Boiler, it literally boils the person's blood from the inside" most of the class paled "Liquefiet ex Parte Organorum, or the Liquify Organs curse, it liquifies the organs slowly causing the person to die horribly" most of the class looked sick "And Agnus Infinitum ICTUS, or the Infinity Tap Dancing Curse, makes a person tap dance forever unless someone knows the counter for it" most of the class laughed.

Harry coughed causing them all to go silent "Right you are Mister Malfoy, 10 points of Slytherin, now" he pointed at Hermione "Name me three light Offensive spells" she nodded "Diffindo, or the Cutting Curse, cuts through anything up to steel level of strength" most of the class blinked at that "Bombarda, the Explosive Curse, makes a large explosion where you are pointing your Wand, explosion size depends on the caster".

More of the students continued to gap "and Confrigo, an unrefined version of Bombarda, a completely uncontrollable explosion, no Wand movements" the Class just gaped. Harry nodded "Correct Miss Granger, 10 points to Gryffindor, now does anyone want to take a guess at why I asked for three examples of each?" Tekuya raised his hand "Yes Mr Vermilion" "You want us to know that be they light or dark, most Spells can be used to seriously injure or kill someone".

Harry nodded "Correct, 10 points to Slytherin, now can anyone tell me what the definition of Dark Magic is?" Ron raised his hand "Yes Mr Weasley" "Dark Magic is magic that has been subjugated and used by Dark Wizards over a certain amount of time, as such being called Dark" Harry smirked as everyone, even the almost hidden Professor Snape stared at Ron is surprise "A well thought out answer Mr Weasley take 10 points, but it is not quite correct" everyone looked at Harry in interest.

Harry looked over them all with a serious expression "Dark Magic is defined as Dark because it is classified as Sacrificial Magic, it takes more magic out of the user to use it, and as such people have died from overuse of that type of magic, it is why Rituals and Blood Magic are frowned upon but my Mother saved me using Blood Magic and Rituals, they can stop things like the Killing Curse, so why can't we use them, it is all by the ideas of the Ministry, that is the reason that the Infinity Tap Dancing Charm is banned".

Harry looked over them all "Someone once said that there was no Dark or Light, I like to think that part of his statement is correct, there is only Magic and how you use it, mind you, there is Good and Evil magics, Soul Magic is horrific were as Emotional Magic is most of the time natural, can anyone give me an example of Emotional Magic?" he looked over the class "No one, Professor Snape, can you name one for me?" everyone turned to Professor Snape who walked out of the shadows "The unforgivables".

Harry nodded and wrote down all three "All of these are completely emotion based spells, another example of a Dark emotional spell would be Fiendfyre, now does anyone want to tell me a Light based one?" Charlotte grinned and held up her hand. Harry chuckled "You are supposed to be my assistant but go on then Miss Anderson" "The Patronus Charm" Harry nodded and pulled out his Wand "Expecto Patronum" the silver Phoenix flew around the room before disapating, everyone looked at Harry in awe "That is also an emotion based spell, one that the Dark Lord cannot cast".

Everyone looked at him in disbelief "Mind you, he is easily powerful enough, but there is a catch, to be able to cast the Patronus Charm, you need to feel powerful happy emotions, the best one for it is Love, love of a family or love of someone close to you, but love is the best way to cast it, can you show us you Patronus Professor Snape?". Severus nodded and pulled out his Wand.

"Expecto Patronum" A silver doe flew out of his Wand and Harry's eyes widened "Lily" Severus nodded, Harry gulped "Thank you Professor, we will have to have a talk about this, come to my office on the Seventh floor after the last classes" Snape nodded and went back to the shadows.

Harry turned to the class "Now, I want you all to practice the Spell Diffindo" he waved his Wand causing all of the Desks to turn into Blocks of wood "And once you think you have mastered Diffindo, practice Reparo, the Mending Spell, like so" Harry turned his own Desk into a block of wood "Diffindo" the Block split in half "Reparo" the block formed back together and Harry reverted it back to a Desk.

Harry watched with Pride as they all began to cast the spells, he watched with glee as Tekuya and Hermione both got it at the same time "10 Points to both Miss Granger and Mr Vermilion for succeeding in casting it properly on their second attempts" both grinned at each other before continuing, Harry caught something in the corner of his eye, it was Pansy sending a Diffindo at Hermione's neck. Within the space of a second Harry's Runic Shields were up and a shield was absorbing the Curse "MISS PARKINSON".

Everyone jumped at the shout and then backed away from Harry, whose magic was swirling around him like a tornado, they then turned to Pansy who was fearfully sneering at Harry. Harry turned to Severus "What do you think?" Severus glared at Pansy "I think, given that if that spell had hit, it would have killed Miss Granger, that Miss Parkinson loses 50 Points from Slytherin, 2 Months detention with Mr Filch and a warning that if something like this happens again, she will be expelled" he turned to Harry "Is that agreeable?" Harry nodded "I shall go and inform Professor McGonagall after this lesson" Snape nodded and grabbed Pansy, dragging her out of the classroom.

Harry's magic disappeared from the air and he turned to Draco and Tekuya "Sorry guys, you did all that work and she went and fucked it up for you" they shook their heads "Nah, Teach, it's all good, I was more surprised with Professor Snape's reaction" Harry nodded "We are trying to have Professor Snape learn how to be a teacher, not just a Potions Master" Draco nodded and grinned "So we can actually go through a Potions class without something exploding?" Harry nodded "That's the plan, now back to it"

(Half an Hour Later)

Harry grinned "Okay Class, I think we all have gone quite far into mastering the Cutting Curse and the Mending Charm, I want three inches of Homework on each spell and what it is used for" most of the class groaned "Now none of that, I could have given you more, now scat, I have to go and see Professor McGonagall" they all piled out of the class, Harry turned to Charlotte "How was I?" she smiled "As always, you are an amazing teacher" Harry nodded and they left to go and find Professor McGonagall.

(Transfiguration Classroom-5 Minutes Later)

Harry knocked on the door "Come in" Harry and Charlotte walked into the classroom, nearly everyone blinked "Professor Potter, don't you have a class right now?" "I did, I have sent them away early with homework, there was an incident Professor" McGonagall scowled "Oh?" Harry nodded "Miss Parkinson decided that is would be a good idea to throw a Cutting Curse at the back of Miss Granger's neck, luckily I had anticipated something so I was ready, Professor Snape has given her 2 months detention with Mr Filch, 50 Points from Slytherin and a warning that if something like this happens again, she will be expelled, is that alright?".

Professor McGonagall nodded "That seems appropriate, I shall talk to Miss Granger later, can you help with this class? they seem to be struggling to turn a pencil into a needle" Harry grinned "Of course Professor, always happy to help" for the next half an hour, Harry and Charlotte helped around the classroom "Now Class, I want 3 pages on this spell and its implications, go to your next class, aren't they with you Professor Potter?" Harry nodded "They are Professor McGonagall, I'll take them up now, come along students".

(A Few Hours Later-Main Hall)

Harry sat down at the Staff Table before turning to Charlotte "You can go and sit with a friend if you want to, I just need to know where you are in the room" Charlotte smiled and nodded before walking over to the Ravenclaw table, glaring at most of them, before sitting next to Luna and beginning to chat. Harry nodded before turning to Minerva who was smiling "What?" "You're sweet on her, aren't you?" Harry shrugged as the rest of the Staff table listened in "We were dating for a week before the Apprenticeship started".

Minerva nodded "How is she doing on that?" Harry grinned "She is a fast learner, she has almost learnt as much as I did in my first month, I'm very proud" Minerva smiled and nodded, Albus leaned over "So how did you find your first day as a Professor?" Harry grinned "It was really good actually, we had a bit of discussion on the difference between Light and Dark, then we started practicing the Diffindo spell, there was an incident but between Professor Snape and I, we had it covered".

Albus nodded "So that is why Severus dragged Miss Parkinson to my office saying that she was being given an official warning because she had tried to murder another student in class?" Harry nodded "She attempted to throw a Diffindo at Miss Granger's neck" Albus sighed "I see, you and Severus handled it well" Harry grinned before turning to Severus "Hey, Professor Snape?" Severus turned to him with a raised eyebrow "Yes Professor Potter?" "How did you enjoy our first class?" Severus blinked "It was rather informative, who did you get that quote from by the way?".

All of the staff were listening in "Ah, that was Tom Riddle's quote, but I didn't finish it, the whole thing is 'there is no Light or Dark, only Power' but in my eyes, I remember the quote 'Absolute Power, corrupts absolutely' so I only agree with the first part, there is Grey magic, Emotional Magic and Evil Magic in my eyes, I see myself as a grey Wizard, because I am willing to use both Light and Dark based magic if the situation calls for it" Severus nodded with a small smirk "I am the same" Harry nodded and they began eating.

(Several Hours Later-After Curfew)

Severus was walking up to the Seventh Floor when he heard a ruckus "Mr Filch, I am a teacher here now, I am not a student" Filch's voice was heard "Whatever Potter, it is about time you got expelled" Severus walked around the corner to see Filch holding Harry by the arm, Harry and Charlotte looked about ready to explode "Argus, what are you doing?" Harry and Charlotte sighed and smiled at him, Filch grinned "I found Potter and his little Girlfriend wandering the corridors Professor, I think it is about time he was expelled, don't you?".

Severus smirked "It is about time, but it will be extremely difficult to pull off" Filch looked confused as both Harry and Charlotte smirked "Why's that?" "Because Potter is now the Defence Against the Dark Arts Professor here at Hogwarts" Filch looked dumbstruck "How?" "He pasted his OWLs, his NEWTs in DADA and Ancient Runes and received his Masteries in DADA and Ancient Runes over the summer, he is a full-fledged teacher here" Filch grumbled "What about the girl?" "She is his assistant and she is…how old are you?" Charlotte grinned "I'm about to hit 18".

Severus nodded "There you have it Argus, so these two are off limits" Filch grumbled and let go of Harry before stalking down the hallway muttering, Harry rubbed his arm "Thanks Professor, one more minute and I think Charlotte would have killed the man, she hates it when I am insulted" Charlotte nodded, Severus shook his head "No problem Hadrian, shall we go to your office then?" Harry nodded and the three of them set off.

(Hadrian's Office-Room of Requirement-5 Minutes Later)

Harry and Charlotte were sat on one couch and Severus was sat across from them on another "So what do you want to know?" Harry sighed "Dobby, bring me a Black Coffee with two Sugars, a white coffee with cream and three sugars for Charlotte and a Japanese Green Tea for Severus, and can you bring me my Moleskin bag?" Dobby nodded and popped off.

He popped back in and handed the item and drinks to the appropriate people, Severus noted that he was wearing the same robes as Charlotte, before he bowed and popped away again. Harry took a sip of his coffee and hummed in delight before looking at Severus "You knew my Mother" it wasn't a question "How?". Severus sighed and took a sip of his tea, noting the delightful taste "This is some good tea, I'll have to get the recipe later" he placed the cup down on the coffee table between the two couches before looking up at Harry.

"Your Mother, Lily Evens, was my best friend from the age of 9 to the age of 15, we were nigh inseparable, even when I was placed in Slytherin, she still continued to be friends with me, then I did a horrible thing, it was one day after the Marauders had bullied me, Lily had stood up for me but I was pissed, I told her I didn't need a Mudblood to look out for me, I was foolish, she never talked to me again".

Harry nodded "That is what you think happened but I heard it a different way" Severus blinked and was about to speak when Harry placed his hand in his Moleskin bag, he pulled out a shrunken portrait and unshrunk it, he smiled at the portrait before hanging it up above the fireplace, it was Lily and James. Lily saw Severus "Sevi, how are you?" James nodded and smiled at Severus, surprising him "Hello Sev, how are you? You cheeky rascal".
