"Mione, why did you hit us?" Ron whined.
"Because you two were glaring at Peter." she replied simply.
"Mione, he killed my parents!" Harry exclaimed.
"I know, but I believe we were sent back for a reason. What if it was to change history and to bring Sirius back? We have to try!" Hermione pleaded.
"I must say, I agree with Hermione." Ginny cut in. "Nothing bad will happen. We could save them all!"
Hermione nodded earnestly. Harry sighed. "Fine, but please let me hate Peter, it's all I've got!"
"Fine, do it subtly, I'm trying to help him remember?"
At that moment, Sirius walked into their classroom. "Hermione! Please get rid of this!" he motioned violently to his face.
Harry and Ron burst out laughing. "You...you used that spell on Marietta! Reusing spells, the twins would be disappointed." ron joked.
Hermione smiled. "Sorry, Sirius. But you told, therefore you need to be punished. It will fade with time. How much time I can't say. But I can say that girls won't want to date you for a while."
Sirius wailed loudly. Ginny sniggered. "Who did you tell anyway?"
"James." he muttered. "But don't worry, he doesn't believe me. He thinks I'm on muggle medicine again."
Just at that moment, the rest of the class entered and sat at their desks. "Right good morning class. I'd like to welcome my godson Harry and his two friends Ron and Ginny. Treat them well." Orion warned.
"Bloody hell!" Sirius shouted. He had just figured out Harry's parentage.
"What's wrong Mr Black?"
"Er, Nothing sir." God that felt weird. "Just wondering is Harry here is related to James?"
Harry smiled. "No, I'm not. It is rather eerie, how alike we are. But then again everyone has their doppleganger somewhere in the world. Anyway as far as I know, I'm the only Potter left in my family."
Orion nodded. "Right, you all did well last lesson with the Boggart, I thought we'd move onto something more challenging." Hermione snorted. "Right, we're going to be learning about Patronus' today. Who can tell me what they are?"
Six hands flew into the air. James sniggered as he took a mental note of all the bookworms he could prank - especially the Newcomers. He still hadn't forgiven them for their stunt at Breakfast.
"Yes Mr...Snape?"
"A patronus is a spell that takes form of your familiar or protector and defends you from Dementors."
"10 points to Slytherins. Mr Weasley, what are Patronus' based on?"
"Oh...er..." Ron's face was blank. "Patronus' are created from your er... happiest thoughts. This happiness repels the dementors who feed off of despair, pain and fear."
"Excellent! 10 points to Gryffindor."
Harry leant over and whispered something so low, that only Remus and Ron could hear. Ron burst out laughing.
"Why are they laughing!" Sirius demanded.
"Harry just said - at least you listened to me."
"I don't get it!" Sirius whined.
"Me either Pads." Remus said confusedly.
"Right, the charm is Expecto Patronum. Everybody say it."
"Expecto Patronum." the class chanted dully.
"Good, wands out. I want everyone to think of their happiest memory or feeling and say the incantation. Keep practising until you get some form of silvery mist. That's the first step." Orion instructed.
Everyone stood up and moved their tables to the edge of the classroom. Everyone except for Harry, Ron, Ginny and surprisingly, Hermione. The four of the were lounging about by Orion's desk chatting and laughing. James noticed this and narrowed his eyes. He moved closer to his fellow Marauders and started talking in hushed tones.
"Harry! Why aren't you guys practising?" Orion asked breathlessly.
"We don't want to show off." Ginny answered truthfully.
"Yeah, that and third year. You knw we can do it, why do we need to learn?" Harry asked cockily.
"Don't be a smart arse!" Ginny snapped slapping Harry around the back of the head.
Orion nodded. "Fine, but you will demonstrate if asked."
The four agreed as Orion walked off to help some Slytherins.
"So. You think you're better than us do you?" James asked snidely.
"No." Harry replied cooly to his teenage father.
"Then why don't you practise with us? Or is your magic that bad!"
Ginny, Ron and Hermione winced. Harry was not going to take that well. They moved away from the two boys and stood next to Remus and Sirius. "Can you guys feel the magical tension too?" Remus whispered. The three friends nodded and gulped. Harry growled.
"The last time someone said that Harry's magic was unstable or bad...they ended up in the Hospital Wing for a month or so..." Ginny trailed off. The two Marauders stared at Harry in awe - it was almost as though you could see the sparks flying between the two teenagers.
"I'm not bad at magic." He took a deep breath and the air around him seemed to ripple with untamed magic. "At least I can produce my Patronus." His eyes seemed to glow with emerald flames. Slowly the air around him calmed down as he took another deep breath. He realised that what he was saying was juvenile, but what did he care? He was finally having an argument with his father, his life couldn't get much sweeter.
"Prove it!" James snapped, confusion evident in his eyes at the air's strange antics.
Harry smirked. "If you insist." By this time, the whole class had stopped working and were watching the two Gryffindors glaring at each other. Orion was watching, torn between amusement and pity.
"Expecto Patronum!" Harry cried. A solid silver stag erupted from his wand and galloped around the classroom before knocking James over with his antlers. The room gasped at the sight of the beautiful animal. The stag cantered over to Hermione, Ginny and Ron, pawing at the ground impatiently. The three teenagers sighed and cast the Patronus Charm too.
One by one, a terrier, a horse and otter flew from their wands. Everyone watched as the four animals chased each other around the room. Suddenly, the otter began to convulse and change form. Finally, after the white light disippated, a ferocious four legged stood in its place. Hermione waved her wand, and before anyone could register what animal it was, it had disappeared. Harry, Ron and Ginny stared at her.
Harry cleared his throat. "Mi, was that...?"
"Yes."
"And do you...?"
"Yes."
"Right. We approve." Harry said with a smile. Hermione smiled and hugged him tightly.
"Right class! Back to work! You should be able to do it with practise." Orion announced. The class turned back to their happy thoughts, eager to create the same corporeal patronus' as the newcomers. All except for James. He stared at Harry seething. No one beats James Potter at Defence Against the Dark Arts! Not even Remus! He narrowed his eyes as he saw Harry smirk.
"Harry." Hermione admonished. "Don't be so mean to him."
"But, Mione. I'm finally having argument with my dad. Do you know how many times of dreamed of how it would go? I'm just so happy." Harry whispered quietly.
The four friends smiled, accepting Harry's very valid yet illogical reasons. They watched as James stormed over to his group and started gesturing violent towards Harry.
"You might be happy, mate, but your dad sure ain't." Ron muttered darkly.
Ginny nodded. "Harry be careful. They have the same look the twins had when they were pranking Umbridge." she warned.
Hermione growled. "If they do anything dangerous I swear I will never talk to them again." She swore loudly.
Unfortunately, the Marauders were so engrossed in their plans, none of them heard her warning.
"Right, so we move this staircase, place these at the bottom. Create a slide into the dungeons charm it so that that happens and then let him out." James muttered quickly. Remus nodded resignedly, while Sirius looked excited, completely forgetting who Harry is.
"Yeah, and let's make it so that their magic doesn't work!" he contributed.
James nodded. "Let's get Peter and work on it during Charms."
