Chapter 2 – Trip back home and a rejuvenating curse

It was only mid day and Sirius was exhausted. "I swear I will never again tease Sev about his love of potions! How can he stand all that tension? At least in my time, we only played pranks on teachers, we didn't try to blow them up!" he mumbled as he went to meet Erwan for lunch after a near death experience with a detergent potion and a Neville Longbottom, two ingredients that should never ever mix.

He turned a corner and walked straight into Draco Malefoy, nearly sending the boy toppling on the floor. He snarled at the boy, angry at the thought of his lunch being delayed. "What are you doing here? Shouldn't you be with the others demons-in-disguise known as students in the Great Hall?"

The young Malefoy sneered. "My father owled me, I'm needed at home. I have the Headmaster's permission to go." He told, handing Sirius Dumbledore's note, which Sirius read quickly.

"Right, consider me warned. You may go." He dismissed Draco before stepping around him and making his way towards the Great Hall at a brisk pace. As soon as he was out of sight, Draco let out the breath he had been holding and ran out of the castle to the carriage his father has sent, which already held his trunk.

Sirius had changed course after grabbing Erwan and, having taken some food from the kitchen for all of them, they went to find their significant others and Sirius explained Malefoy's departure.

They discussed the reasons why Malefoy could possibly be called back home, Sirius throwing some of the most ridiculous theories he could think of in the discussion and was rewarded by the smile that blossomed on his husband's face. As soon as the last ustensils disappeared, he pounced on Severus and snogged him like there wouldn't be any tomorrow. This course of action gave Remus some ideas of his own, and soon everybody was cuddling with his husband.

Malefoy Manor

Draco was standing in his father's study, concentrating on the intricacies of the sculpture his father used as a paperweight as he was waiting for his genitor to end his speech.

"I wanted you here because I need someone I can trust. You are to survey the House Elves, everything must be perfect. They are going to agence a room. There will be a reunion here with some powerful investitors. It is high time you learned your role. You're dismissed."

"Yes Father."

On his way out, Draco passed his mother. She seemed sad, but she managed a small smile when she saw him. She squeezed his hand reassuringly before knocking on the door of the study and entering when told.

Draco sighed 'I swear I will find a way to get you out of his clutches, Mother, even if it means asking Potter for help.' He promised himself.

As soon as his parents had left, he went to the House Elves, and, reassured that they had everything under control, he resumed his favorite past time while at home, exploring Malefoy Manor.

Hogwarts

"Hum, guys? May I be a party breaker and ask what you found in the books yesterday after we left?" Erwan's words froze everybody.

Severus sighed and put his head on Sirius' shoulder. "Nothing, nothing at all, damn Merlin!" Sirius snaked his arm around Severus to brought him nearer to himself.

"I fear it was a spell Lily created specifically for us. Trying to recrate it would be too long, and hazardous." Remus quipped from his sprawled position on Erwan's lap.

"So, I suppose we should go to Dumbledore, then?" frowned Severus. "You know, you're not obliged to do it, guys..."

Sirius cut him with a quick kiss "I can't speak for Erwan, but I fully intend to keep my word to you." He smiled, "Do your worst!" he theatrically stood up in front of his husband, and gave him his wand.

Severus grinned and, accepting the wand, he pointed it at his husband and murmured "Glamoris Purgis". As soon as it was done, he smiled and kissed him deeply. So involved were there in their kiss that they forget they were not alone.

Remus' commentary of "cute, sickeningly sweet, but indeniably cute" reminded them of their friends' presence. They both blushed.

All the eyes were attracted to Erwan when he suddenly jumped on his feet. He grinned impishly "Well, sorry to interrupt, but you won't be able to see me looking younger..." His words started a chaos of protestations.

Remus stood nervously "But, you promised..."

"What on Earth do you think you're doing?" Severus frowned.

"How could you?"

Everybody stopped short when they heard Erwan's snort of laughter. "Hey guys, chill! If you had let me finish, you would know what I was going to say... you won't be able to see me looking younger yet. Someone has to go and fetch Dumbledore, I doubt he would come if we firecalled him."

"With him you can never tell." Shrugged Sirius, safely ensconsed in Severus' arms.

"You! I can't believe you!" huffed Remus.He playfully swaped his husband's backside.

Before closing the door, Erwan winked to Remus "I'll repay you tonight, love. You three should be working on this wizzard's oath."

He didn't noticed the black haired teen lounging in the shadows before he closed the door. "By Merlin's socks!" the teen murmured before adding "I should warn him. I just hope they don't destroy Hogwarts." He shook his head and shrugged before going on his way.

Erwan sighed when he reached the door of the Headmaster's office. He straightened his clothes and raised his hand to knock. He was scared nearly out of his robes when the door opened, revealing Albus Dumbledore himself.

Erwan squeaked and breathe deeply before feeling his voice steady enough to speak. "Headmaster, don't do that, or I'll die before I'm twenty!"

Dumbledore raised an eyebrow but didn't comment. "I was on my way to see how Remus was doing. He seemed a bit off this morning. I hope he is not sick..."

"Well, you see, it is part of our problem..." trailed Erwan. Seeing as he had some trouble finding his words, Dumbledore offered him a candy "Lemon drop, my boy?"

Exasperated, Erwan sighed "Now is not the time to eat candy, Headmaster! It's serious, Remus, Sirius and Severus are involved too!"

Dumbledore's only outward show of surprise was a small widening of his eyes 'If those four are involved, this is not good at all!' he thought, having flashbacks of all the pranks they had pulled through the years.

Impatient, Erwan tugged on his arm and pulled him into motion "Please sir, you must come with me! We are in trouble with a capital 'T' here!"

Dumbledore followed him swiftly. When they arrived, Erwan opened the door and let the Headmaster in. "Please have a seat, I'll be right back."

Erwan went to knock three times on the bedroom's door before entering the room.

"So how did it go?"

"Hush love, everything is fine. Are you finished with this oath?"

"Yes, here it is." Severus handed him a piece of parchment. Erwan quickly scanned it before nodding "Short and direct to the point. Superb."

He kissed Remus before going to join the Headmaster.

As soon as he caught sight of him, Dumbledore stopped his pacing. "This has better not have anything to do with a prank." He warned Erwan, scowling.

"No, this is real, no matter how I wish it was a prank. But before we go further, I need you to take this oath." Erwan gave him the parchment, which Dumbledore quickly read.

"Are you serious?" Albus asked, studying Erwan's face carefully.

"I am. Will you do it?"

Sighing, and dreading the revelations that were protected so carefully, Dumbledore put the piece of parchment on the table and read it aloud slowly.

"I, Albus Dumbledore, swore this day, with Erwan Lupin-Mac Connor as witness, that I will never, in any way or form, reveal anything that Erwan Lupin-Mac Connor, Remus Lupin-Mac Connor, Sirius Black-Snape or Severus Black-Snape, or any of their relatives or friends tell me this day; or anything relating with this 'situation'. If I was to break my oath, without their konwledge or permission, let me be stripped of my magic and live as a muggle for the rest of my life."

Finished, Albus cut one of his fingertips with a small razor charm, and drop three drops of his blood on the parchment, which shone a bright yellow, sealing the oath, before triplicating itself, one copy for Dumbledore and Erwan, the third for the ministry.

After storing his copy in the desk, Erwan clapped his hands. "Pfiuu! That's a good thing. I'll be right back. Don't move!"

With those words, he ran to the bedroom and threw the door open. Albus could only heard him stating that it was done before he closed the door.

When it reopened, he gasped as he saw a younger version of Severus entering and going to sit on the second couch, in face of his own. His shock level skyrocketed when the sight of a younger Remus and Sirius confronted him.

"What? How?..." his brain nearly short circuited.

"Well" Sirius smiled, "we will answer better with a simple demonstration. Guys?"

Erwan went to stand between the two couches with Remus who draw his wand.

Dumbledore, nervous, eyed the two young men sitting peacefully on the couch holding hands. Intercepting Albus' eyes, Sirius smirked and said "We can do this only once, so I suggest you look at the spectacle!"

Severus frowned at him. Sirius grinned "Well, it's true, he should!" Rolling his eyes, Severus cut him with a kiss.

Dumbledore politely reported his eyes on the two standing people. With a flourish Remus pointed his wand at Erwan and carefully enonciated "Glamoris Purgis"

Dumbledore's eyes bulged when he saw a nineteen years old Erwan. He fainted with shock.
