- "Avada Kedavra!"

Corvus opened his eyes without moving a single muscle, still sweaty and hard-breathing. Same dream every night, same spell, same person in front of his wand, and the flash of light and screams, it was his worst nightmare, his personal Boggart that could not be repelled with a counter-spell. He wasn't afraid of using a Killing Curse, nor he was afraid of murder. No, he's greatest fear was to see he's mum at the receiving end of the Killing Curse, his own Killing Curse, the one out of two people that gave a damn about him, even if that was in her own, twisted ways.
Turning his head a bit, he made a motion with a hand and hour drew themselves in front of his eyes: 4:57am, it was time to get up. Morning routine was the same for ten years: get up, get dressed, ten miles running, half an hour spellfire training, go back, get into the shower and to the Great Hall for a breakfast. So, being up to a routine, Corvus dressed, put a notice-me-not charm, silent steps charm and toped it off with an overpowered disillusionment charm, he raced out of his room and Slytherin common room into the dungeons, passing through one of many secret passages, five minutes later he was already out of the castle, near the shores of the Black Lake. Starting his usual run, always broth him some old but never forgotten memories of passed days, but this time it was a very specific one…

May 13, 1983

It was almost a year since Harry was rescued by Lestrange couple from that hellhole. Today was the day he had to be adopted officially and magically into Lestrange House, but before that was training, that was established by Bellatrix, his soon to be mum, gruel and intense training regime, to be able to protect himself and his House in case of attack. At least that was what Bella told him, - "You have to become strong, physically and magically", - those words were an ever persistent echo in his mind, said with sweetness and concern, never experienced before, Bellatrix was having genuine concern for him, even if she or Rodolphus rarely show it as an emotion.
Harry's training was always supervised by Bella or Rody, sometimes by his, soon to be uncle, Rabastan even if he didn't shown any kind of care for the little kid, on the contrary, sometimes it seemed that he wanted to kill him or badly injure. Days went by, and boy noticed some changes of his body, he was taller with even darker shade of hair, but most importantly his emerald eyes, where now grey with a slight shade of violet in them. As of what he learned from different lessons that Bellatrix hammered him with, and books from Lestrange library, children under eleven, were to 'devour' some of the magic around them, mostly by their parents, that's why most magical look to much a like their parents, so sooner or later Harry will resemble a lot more Rodolphus or Bellatrix, than his biological parents.
The ritual took place in a dungeon of Lestrange Manor, during midnight, where Harry was awaited by Rodolphus and Bellatrix. It had to be done in very specific order, the subject had to be put on the altar, by his left had to be a male parent, by the right – female one, both with one hand in his palms, the other on the boy's forehead, by the other side was Rabastan, starting chanting in some language Harry did not understand. Soon after, he stopped and looked at his brother and Bellatrix, - "Now the hard part, the words", - couple nodded in response.

Rodolphus was the first to speak up, - "From this moment you are a member of Ancient House Lestrange", - an unimaginable pain stroke Harry, he was warned about the pain but never he would imagine that it would be so strong.

By turning his head to Bellatrix, the boy saw her eyes in tears, she didn't wish for him to suffer more that it was needed so she hurried up and said the second part of the adopting ritual, - "I name you Corvus, Heir of Crows and Wolfs", second after even stronger pain passed through boy's body, and he stopped squirming and screaming.

- "Success?" - with a shaking tone asked woman to a nobody in particular.

- "We have to wait and find out" responded Rabastan making a step closer to a still body of a boy, that was looking somewhat pale and cold to touch.

- "He'll make it" with a hushed voice said Rodolphus, turning his head to Bella, - "He's strong Bellatrix, strong enough to survive". Long minutes passed, but everyone stood there waiting for 'if' or 'when' the boy would wake up, except Bella, who kept squeezing her, now, son without taking her sight from his face. And it happened, the boy opened his eyes, his beautiful violet eyes, a carbon copy of his, now, mum eyes. Rabastan took a step closer to his nephew, beside him was his older brother with a wide grin directed to his wife and a peculiar expression telling her 'I told you so'.

Putting his hand on his son's forehead, - "Rise, Corvus Rodolphus Lestrange, Scion of House Lestrange" magic sealed the ritual, Rodolphus and Bellatrix had become parents and Harry, now Corvus, their son.
Nobody noticed when in 12 Grimmauld Place on the family tapestry, appeared a new name, the name of Corvus Rodolphus Lestrange.

November, 1993.

Corvus was returning from the showers to his dormitory right before everyone awoke, putting his robes on, he started to walk out of the dungeon and to the Great Hall for a breakfast, without knowing how this day, will change his future.
Strolling down the corridors, under heavy Notice-me-Not charm as usual, a neat little way to not draw attention, that Corvus learned in his first year, as per his mother orders, to stay out of sight and not to drawn any kind of unwanted attention, an order that he spectacularly failed last night when he saved that Granger girl from a troll.
Morning in Hogwarts Great Hall was a usual rowdy and loud, students eating, chatting or doing their thing, not given a damn about other people comfort. This morning was no different, as Corvus entered and took his usual seat at the end of a table as far away as possible from professors table, putting something to eat on his plate and water into a glass, he never quite understood the fascination that the students had for pumpkin juice as his eyes spotted a jar full of it, - "Troll piss", - muttered under his breath, and started eating. Eyes were wandering, as usual, he saw his House students, Malfoy and his little band of idiots specifically Crabbe and Goyle, what surprising for Corvus was that Daphne Greengrass was with them, she was a fifth year and usually kept to herself not making any contact with anyone except her sister Astoria. Their chat was interrupted, when Daphne notice Corvus looking at them, even through notice-me-not charm, started to walk in his general direction, but suddenly stopped when she saw his hand twitch putting it on the table knife. Something in the boy's mind screamed 'Danger!', having the same feeling Greengrass averted her gaze and walked pass him and out of the door. Waiting for another minute, to check if she's really gone, he returned to his breakfast, suddenly on the other side of the Hall the boy spotted a girl with a bushy hair and hazel eyes, sitting alone at the end of Gryffindor table with a book in front of her.

Last Night

- "My name's Corvus. Corvus Lestrange.", - Why did he said it like that, it was cheesy as hell, and why had he told her his last name, even thou she would learn it eventually, but still.

- "Thank you", - adjusting herself and sitting eventually with her back at the wall, she continued, - "I'm Hermione, what happened anyway?"

- "It was a mountain troll, an adult one at that", - sitting himself in front of a girl, never averting his eyes from her, - "You're lucky to be alive".

- "Lucky, you have been there to save me", - with a smile, still a little confused, Hermione answered.

(I recommend putting 'Love Still Has a Place' by Aaron Kellim and Jay Denton, for this little scene)
Blush on Hermione face was obvious as day, there was something in that girl, something familiar and at the same time alien, like he knew her for his entire life but at same time they only just met, it was most unsettling and irritating. She was by no mean beautiful, her hair was too bushy, eyes to deep, smile too large with those frontal teeth that at the closer look, made her look like a beaver. But the combination of all of those traits clicked in Corvus's mind, something primal, something warm. His hands started to shake, heart pounding, wanting to say something, but couldn't, - 'What's happening to me?', - was his only thought when looking into those hazel eyes. He helped her on her feet, still holding her arm in his hand, unable to let her go or take his eyes from hers, strangely enough she never averted her own sight from his violet eyes neither. Again, a smile from a girl, and again even warmer feeling, her hand now on his arm, something had to happen, they started to shorten the distance between their faces, close and closer, suddenly a thought in his head, - 'Is she…'.
(You can turn off the song now)

Pain in his right arm broke him from that thought and a moment they shared, as the sound of incoming steps, and no sooner there were three figures in front of them.

"What in Merlin's name happened here?"

It was professor McGonagall's voice, she was standing there with professor Snape and Flitwick, darting eyes to a 'couple' and back to a body of a troll, she wasn't pleased, as usual.

- "Professors", - with a small nod answered Corvus, with his eyes back to Hermione, as if out of fear she would disappear the moment he'll take his sight from her.

- "I'm still waiting for a suitable answer Mister Lestrange, what happened in here, why are in the girl's bathroom with miss Granger and why there's a dead bloody troll on the floor?!", - rising her voice even louder with last sentence, trying to put as much pressure as she could on the Slytherin boy.

- 'Is she trying to put some kind of blame on me, or McGonagall is just plain stupid?', - those were Corvus's thoughts every single time that transfiguration professor opened her mouth on him. But before he could give her a piece of his mind, Hermione interrupted, - "It was my fault professor, he tried to help me, if it wasn't for Corvus, I'd be dead.", - It was refreshing to see a Gryff protecting a Snake, but Corvus wasn't going to complain.

- "Maybe we should be asking what an adult troll was doing in castle in the first place Minerva?", - Snape, head of the Slytherin, wasn't boy's favourite man in the world, but he looked after his own, even if he didn't give a goblin's ass about Lestrange, he was still a Snake, so that meant his protection would extent to the boy too, this time.

- "I'm sure that Headmaster would get to the bottom of it", - and that was a half-goblin Charms professor Filius Flitwick. Corvus never had any problem with him, apart him being half-man. - "What intrigues me more, is that, how did a fifth-year could've slain an adult troll.", - now Corvus hated that shite faced professor, just as he turning his goblin-smug face to the boy.

- "All's in due time, I believe your student needs a medical attention", - Snape again saved Corvus from stupid '100 questions' by pointing out Hermione's condition, - "That of course if mister Lestrange would be so kind and let her go…"

Embarrassment got a hold of the boy so he let go, even thou Hermione did it to alas with less notion just as Flitwick escorted her out, McGonagall started ranting again, but his mind was occupied with those hazel eyes in front of him, just as Hermione left.
Few stupid questions later, and a short 'lesson' on the use of dangerous curses, Corvus was dismissed to his room, after an utmost boring explanation that he's okay, wasn't in need of medical help and a fifty points award from Snape, was excused and returned to his dorm. On the way to it however, Corvus couldn't get rid of the thought that today event set in motion something, that'll not be forgotten or ignored.

Now

Again, Corvus was pulled out from his thoughts, this time thou it was a kiss to his cheek, by no other than Pansy, that immediately sat beside him with a swift and elegant manner, the usual one.

- "Daydreaming again?", - Pansy's soft voice murmured in his ear, dangerously close to what would be almost intimate interaction.

- "Just analysing… er, last night, that's all.", - Not to give his real motive, he turned his head to her and returned the kiss.

Pansy Parkinson, was seventh year Slytherin, and as many would claim Corvus Lestrange's girlfriend. They started dating a year ago, basically out of nowhere when he visited Parkinson Manor with his uncle Rabastan on summer day last year. From a simple point of view, she was perfect for Corvus, not cute but elegant in her own way, she came from a Dark family, just like him, was a best student in her year and a top 5 in Hogwarts, and a Head Girl plus a champion of the Duelling class. But the best thing for a young Slytherin was that she understood him completely, never lied to him, and never asked unwanted questions, which was unheard of in the House of Snakes.

- "Yeah right", - that was another one of Pansy perks, she had a perfect sense when someone was evasive, so she did not press the matter any further, - "Congrats on killing the troll, not a small feat, you have to tell me everything about it after classes".

- "Why's that? I'm free now", - with a smile answered Corvus, adjusting himself so he could look straight into her face, and putting his hand on Pansy knee.

- "No such luck for me, have double Potions, I hate those", - taking his hand from her knee, and adjusting herself to a table.

- "I can relate", - adjusting himself too, so he could better see her pretty face while she eats.

They were talking for another few minutes of nothing specific as Pansy was finishing her breakfast, and trying to plan their Hogsmeade trip on weekend, as nothing significate happen of late, something like that was normality for Pansy and Corvus, and not something extraordinary, even if killing a troll wasn't something they've done as a hobby.
After finishing breakfast Pansy gave him a kiss, - "I'm off, try not to make any more trouble than you can handle, at least not without me", another kiss on the lips this time and a wink, she was gone and Corvus remained alone again, seeing that it was time to get to Duelling class, he stalked out from the Great Hall.

- "Heard you saved Beaverface, how noble of you", - Midway through a corridor Corvus was interrupted, by one of the three persons who he had no desire to see, hear or talk to. The third-year Gryffindor boy who spoke to him, was in the company of other two, Weasley and Finnigan.

- "Good day to you too, Potter", - turning himself to face the trio and making a step forward, - "It always amazed me, how you actually resemble Malfoy, with that smug attitude and two idiots following you around, are you sure you are not related?".

- "What did you just say?", - it was clear that Potter always fumes as soon as somebody remind him of his attitude resemblance to Draco, his archnemesis.

- "I said", - putting his most Snapelike attitude, and making another step froward, answered Corvus glaring at Adrian Potter and his dimwits of friends, - "I did what was required of me as a prefect, in other words, my duty. A concept you clearly lack, just as tact and decency non to offend your fellow housemate and a girl, by calling her names.".

Potter wasn't brightest of the bunch, but even he understood when there was nothing to be sad, and just glared red-faced at Slytherin prefect that already turned his back on him and started to walk away. Weasley however, never had any sense to begin with and felt insulated, that someone had the nerve to take down a notch the boy-who-lived, and tried to send a stinging hex in Corvus's back. That was a mistake as Slytherin turned 180 and deflected the hex with his left hand, back at Weasley face, amplifying its effect in the process, second after and the red-head dimwit was on the floor clutching his face crying.

- "I'll let it go this time, because of your friend's clear mental disabilities", - he turned his back again, but this time waited a few seconds and continued without turning his head, - "But should you do something like that again, make no mistake, it will not be a stinging hex that will hit you in the face Potter", - message was clearly delivered, Potter and Finnigan took their friend and left for the hospital wing.
The day only begun, and it was already shitty, what would happen next, nobody could've predicted, as quiet and calm life of Corvus Rodolphus Lestrange changed, the moment that in front of him appeared a tense bushy-haired girl with nervous looking eyes, staring at him.

"We n-need to talk".
