Chapter 3 – Explanations

"Do you think we killed him?"

"No, don't be stupid!"

"I'm not, but at his age..."

"Are too."

"Am not!"

A sigh. "Stop it, Padfoot, Grumpy Bear!"

"Look, Wolfie, he's waking up!"

Dumbledore opened his eyes to be confronted by the same vision. He satup stright and sighed. "So, what happened, and how? Is it temporary or permanent?"

Everybody turned to Remus. "Why me?" he wanted to know. The others shrugged. Remus shook his head and sat near his husband.

"Well, you remember this accident we had with a potion in our sixth year?" The Headmaster nodded.

"I was working on the deaging potion. It was nearly completed..." He rolled his eyes as Sirius sniggered "It was nearly completed when Lucius ran into the classroom to hide from Narcissa. Soon after she came in, knocked the cauldron with a Petrificus Totalis, which was previously aimed at myself. Lucius added an Impedimienta to the mix. It rebounded from Narcissa's shield towards us. The mix of the potion and the spells was unstable, and there were some blue sparks running on the floor. We lost consciousness then." Remus stopped his narration to take a great shuddering gulp of breath.

Dumbledore was frowning. "Alright, that explain how it happened. But not what happened."

Remus cleared his throat "You remember that we woke up seven days after the incident?"

Dumbledore nodded.

"Well after this, we remarked that we didn't age as normal people do. After some comparaisons and calculs, we maanged to establish a sort of scale. To make a long story brief, it takes us seven years to age one. So now, instead of being thirty six, we're actually nineteen. Oh, and we change age on the anniversary date of the accident."

"But how do you know this? You could be thirty six and only looking like nineteen years old."

"We were very thorough. We casted the Age Revelae on each others. We even had Lily to cast it for us." Answered Severus.

"She was the one to come with the enhanced glamour we used." Sirius piped in.

"We promised each other that if one was to be discovered, the others would stick with him." Added Erwan.

"So, here we are." Finished Remus.

Dumbledore blinked, trying to digest this avalanche of facts. He massaged his temples to fend off a migraine. Once everything was clear, he voiced his next question "Why didn't you came to me when you noticed the first effects? There could have been some nasty side effects..."

Severus stood and paced, as was his wont when he was agitated. "We couldn't. And no," he dismissed Albus' objection with a wave of his hand, "it was not a question of trust. We didn't want the ministry to put its nose into our lives. Could you imagien what would have happened to us if our secret was known? We would have been locked away, people might have fight to try and capture us, and what if information leaked into the press? Not only would we be probbed and tested, but some of us may also be killed to be dissected, or even worse vivisected..." Severus stopped his pacing when Sirius came barelling into him. He enfolded him in his arms and hugged him tightly. "We were only protecting ourselves and our loved ones."

"Besides, if there was any troubles relating to health, I would have known." Erwan quipped, his hand gripped by Remus'.

Dumbledore nodded, frowning. Even if they made sense, there was still something nagging at his mind... "Wait a minute, it was written relatives in the oath you made me take, but Sirius' parents doesn't count, Remus' own are dead, Severus' are in the USA, and yours disappeared in South America three years ago... But something tell me you didn't told them about this... situation, am I right?"

"My parents know, they're our lawyers." Severus said.

"Well" Remus looked at each one in turn, getting nods from all of them, "there were no side effects or maybe what can be considered as such."He stopped, unsure on how to go on.

"A three kilos and a half, wriggling side effect..." smirked Sirius.

"Make that two" Remus cut in.

"Or even three, maybe four" mused Erwan.

Dumbledore was as speechless as he would be if they had told him they wanted to take over the school to make it Hogwarts school of Pranks. Sirius' voice brought him back to the present.

"Two of them are on their way as we're speaking." He grinned sheepishly under everybody's stares. "Well, he took his oath, and we'll need his help to protect them."

"Well, what is done is done" Severus hugged him.

A few minutes ticked away, and then a scuffle was heard at the door.

"What are you doing here?"

"Well, what are you doing here?"

"I was the first to ask! And if you must know, I'm here to see my godfather!"

"Well, me too, but without god!"

"Huh?"

"Very articulate, Potter!"

"Oh, shut up!"

Remus opened the door to reveal a glaring Harry Potter and a smirking Blaise Zabini. Blaise entered and adressed the room. "So, why the convocation? I swear I was a good little boy!"

Sirius and Remus burst into laughter while Severus scowled "Didn't you mean a good little Slytherin?"

"Of course. But it's only a detail." Blaise sat on the floor and grinned at the assembled men.

Harry was thunderstruck, Dumbledore sighed.

Just as Remus was closing the door, a foot wedgeed itself in the opening. "First, you call me here, and then you close the door in my face! You should make your mind up, you know." Remus reopened the door and smiled apologetically to the mock scowling teen.

"Oups, sorry Terry!"

"Humpf! Unworthy werewolf!" the insult was anihiliated by the big smile adorning Terry's face. He hugged Remus tightly and went to sit near Blaise.

Harry was rooted in his spot near the door, his eyes fleeing from one person to another. "Harry? Are you alright?" asked a concerned Remus.

Just as Harry was about to answer, there was a muffled yelp and a cry of "Sev!" before Sirius began giggling under Severus' tickling assault. Blaise sighed, stood up and put his hands on his hips. "Kids!" he bellowed "stop playing!"

"Sorry" Severus apologized, Sirius was still trying to catch his breath.

"Some times I wonder who are the adults with you!" stated Blaise before plopping back near Terry.

"He started it!" retorted Severus.

"Did not!"

"Did"

"Did not!"

"Did too!"

"Dad, Father, enough!" Blaise turned towards Terry, who was snickering. "Oh, shut up! Your fathers are not really more evolved than mines, you know!"

Harry fainted.

"Woaw, two in one day!" commented Remus.

"You didn't warn him?" asked Blaise incredulously.

"Of course not! It would have endangered the secrecy. And it would not have been nearly as fun." Answered Erwan as he was carrying Harry to put him on the couch near Dumbledore.

"That's official" moaned Blaise "I am sixteen and more responsible than my parents."

"Well" grinned Sirius "You always are too serious, little Blaze!"

"You wouldn't guess, with a name like his. He must have inherited your contrariness." Severus retorted, throwing his arms in the air.

Blaise burried his face in his hands "Incorrigible"he mumbled.

Harry slowly opened his eyes slowly. 'Woah! I had the strangest dream!' He slowly sat up to be faced with a concerned Blaise, who had jumped to his side when he had heard him waking up.

"Potter, you alright? I'm sorry, but I think your godfather have been a bed influence on my father..."

"I'm alright, perhaps..."

"What will it be? Alright or not?"

"I'll be alright but I want to clarify a point. I think I heard you saying that Sirius was one of your fathers?"

Blaise sighed. "I did. I'm Sirius and Severus' son. By the way, Terry here is Remus and Erwan's son."

"I must have missed something there..."

"Okay, I'll explain. Are you sure you're alright?"

"Blaise, stop mohenning him!"

Seeing Dumbledore and Harry's twins looks of confusion, Blaise sighed deeper than before.

"Don't worry, you'll get used to the Terryisms once you've spent some time in his company."

He turned to Blaise. "I think the word you're looking for is 'mother-henning', Terry."

Terry shrugged "Same thing."

Dumbledore brought all eyes on him as he gasped audibly and ran to the door. Before leaving, he turned to the confused assembly. "I have to go, a previous appointment. You'll assure your classes as your relatives. You will introduced to the students this evening at dinner. Now, I've got to go, see you later!" In his head, a thought was on auto reverse 'the Deadly Duo is related to the Marauders! That is so not good!'

"Where did he ran to this quickly?" encquired Remus.

"Probably to make sure he didn't forget to pay the insurance fee for the school." Shrugged Blaise.

Harry waved "Hey, remember me? I'd like a few explanations, cause I'm completely lost here."

Everybody exchanged glances before Sirius got up to seat near Harry. "Ok, Harry, I need you to listen to me without interuption, can you do that?"

Harry nodded.

"You remember how I married Sev?"

Harry nodded a new.

"Well, during our sixth year, we, meaning Sev, Remus, Erwan and I were involved in a slight potion accident. A mix between a deaging potion, a Petrificus Totali, and an Impedimienta. As a result, we age only one year in seven normal years."

"At least, we didn't have to do everything seven times faster than normal!" quipped Remus.

Erwan restrained him in his arms. "Where and when did you get a hold of chocolate?"

Speaking a little louder to cover the bikering, Sirius went on. "Well, your father and Lucius were involved in this, too."

"You mean they..."

"Yes, they have the same 'side effects'. Besides, they were a couple while in school. And James.. He...We all found we were pregnant at the same time. Lucius and him decided to separate because at this time, Lucius had problems with his family, who was supporter of Voldemort. And we all know how he resolved this" he aparted bitterly before resuming "Soon after, Lucius was forced into marrying Narcissa and taking the head of his familly."

"If I get this straight, you mean that I am..." he gulped nervously.

"Yes, you are Lucius Malefoy's son and Draco Malefoy's half brother."

Harry fainted again.

"Well, he took it well." Pipped Terry.

Everybody groaned while Remus took Harry to let him rest comfortably on his and Erwan's bed. They sat and played poker while they waited for him to come to.

Harry shuddered. In his deam, it was becoming weirder and weirder. For example, Sirius, helped by his husband, Erwan and Remus were running after him with big hammers, trying to wack him on the head. Blaise Zabini was helping him to stand while Terry Boot was sitting cross legged on the floor, reading strange aphorisms from a big old dusty book.

When he reopened his eyes, he groaned one more time. Reaching the door, he nearly banged his head on it. Here were the four last Marauders, playing poker with Bertie Bott every flavour beans as bargaining chips. Each time one of them lose a hand, they had to close their eyes, chose a bean and eat it. Terry and Blaise were discussing something sprawled on the floor.

Everybody stopped what they were doing and faced him, Sirius surreptitiously taking the chance to throw the dark green bean he had picked in the fire.

"Harry, you're awake!" shouted Remus. With his heightened sense of smell, he had been able to pick only sugared beans and couldn't hold still. He turned to the teens, and his amrs waving madly, he exclaimed " Blaise, Terry, he's all yours, we have to cast glamours on ourselves to be introduced as our relatives to be able to go on with our teaching duties!"

"Breathe, Remus, breathe!" teased Sirius.

Erwan scowled at the two "And don't confuse him more than necessary" before running after the hyper Remus. "Better check what he is up to!"

Harry eyed the two curious teens warily. "So, what do you want to know, Potter?" Blaise broke the silence.

Harry sat near them, and reached for a sandwich from the plate on the nearby table. "So" he spoke between bites, "if you're Severus and Sirius' son, why don't you have the same name?"

"Secrecy and protection, Potter or should I say nevrosis of persecution?" smiled Terry.

Harry's eyes bulged.

Blaise sighed "Don't mind him. You'll get used to him in a while... or not..."

Terry shrugged.

"So, as to answer your question, Zabini was my grandmother's maiden name, on Severus', my father, side. And before you ask, they know about all of us, they are our lawyers, as well as yours."

The boys spent the dinner time getting acquainted, Blaise explaining everything to Harry with some not always opportune interventions by Terry.

In the Great Hall

"Students, teachers. Before we eat, I have some news. The professors Snape, Black and Lupin as well as Mister Mac Connor had to go on familial business. They sent remplacements, gentlemen?"

Four young men stepped in front of the teacher's table. Two of them (Sirius and Severus) looked like twin younger versions of the old professor Snape the students knew. The only difference were their bright blue eyes.

The two others were clearly different, one with black hair and brown eyes, who was slightly bouncing into place, the other, blond with the same eyes trying to restrain him with an hand on his arm.

Dumbledore designed the first two, which the students had already dubbed as the Twins, as the potion Master's replacement. "Those gentlemen are Shaï and Simian Snape. They'll share the potion class."

He moved to Remus and Erwan "Those two other gentlemen will share the DADA class. Let me introduce you to Corwin (Remus salutated) and Julian (Erwan smiled while grabbing Remus' arm to prevent him from running around) Mac Connor. They are cousins."

The four smiled tightly, reassured by the way the students welcomed them. Before coming in, they had had a quick word with Dumbledore, deciding that keeping their names would be better.

As soon as the student's welcome had died down, they went to sit at the teacher's table. Sirius, Severus and Erwan were soon attacked with questions from all the teachers, Remus too busy eating to noticed.

Well, a long chapter to compensate for my lack of inspiration on this fic. I'm stuck after the fifth chapter...
