Chapter 1: The Mistake

The mistake, that's what Regulus was. He was the forgotten son, the unwanted one. Conceived because of Orion and Walburga's carelessness, or that was at least what his Great Aunt Cassi had said one time. He was still payed attention too, but he was always compared to his family why couldn't be as bold and opinionated as his cousin Bella, as clever as Dromeda, or as likeable as Cissy? Why couldn't he be as perfect as Sirius? Even thought he looked like a miniature version of Sirius, they were nothing alike. Sirius preferred being the center of attention, well Regulus, Regulus liked to sit either in his room or the Black Family Library with his nose in a book undisturbed. Currently a seven-year-old Regulus was in his room reading a novel called "Grindlewalds reign"

'Master Regulus' Regulus turned towards the voice to see a house elf bowing low in his direction. ah his one true companion, his personal house elf Kreacher. He was the only person whom Regulus could talk to and receive praise and support from.

'What is it Kreacher?'

'Mistress black has sent Kreacher to fetch young master, she is waiting' this was odd, mother rarely sent for him unless it involved his Pureblood studies.

'Tell her I'm coming Kreacher'

'Anything for master Regulus' said the elf bowing low before disappearing in a crack. Regulus couldn't help but smirk. Out of him and Sirius Kreacher was the only one in the family who liked him better then his brother.

When he got to the sitting room he found his mother and father standing in front of the fireplace. Both had their cloaks on beside them stood Sirius in his Pureblood aristocratic mask.

'ah Regulus' said their mother noticing him coming in 'were off to the Nott's, Sirius is in charge' after seeing his nod she and father went into the fireplace and vanished. As soon as they left Sirius dropped his mask and grinned down at Regulus. Mother and Father had no idea how different Sirius was when they weren't around. In the family's company he was the perfect Pureblood heir but in reality he was what his parents called a blood traitor. One time he had overheard a conversation between Sirius and their cousin Andromeda over some mudblood named Ted Flonks or something. He had been shocked when he heard Dromeda saying he wasn't so bad and even more shocked when he heard Sirius encouraging her to talk to him. That was when Regulus started to call Sirius what he truly was, a Blood Traitor. But Sirius had just laughed that off saying he "shouldn't always believe all the things his parents preach".

'Well Reggie I'll be gone for some time'

'You can't leave mother put you in charge and any ways where would be flying off to?' Regulus asked suspiciously

'I'm going to meet someone'

'who?' as far as Regulus knew Sirius didn't really talk to the other pureblood children unless he had to

'It's a secret O brother of mine' he replied grinning

'Well I'm coming with you' countered Regulus

'Fine, but you won't like it' ignoring his brothers warning Regulus followed him out of the house and into the muggle park across the street.

'Why are we in this filthy….' Before he could finish his sentence Sirius had already left his side and was talking to a dark haired boy who looked to be around Sirius's age. Everything about the boy was muggle, from his filthy clothes to the disgusting way he held himself.

'Sirius why are you talking to this grimy Muggle?'

'I don't smell that bad do I mate' the muggle joked to Sirius

'Well do you want my honest opinion' Sirius teased back.

Wait was this the person Sirius was going to meet? A filthy disgusting no good muggle. What was he thinking? What would mother say if she found out? Regulus had to stop this "situation".

'Sirius stop talking to him! When mother see's this….'

'she won't see this Reggie and you won't tell her' said Sirius sharply daring Regulus to say something else

'Blimey what's with your brother mate does he have stick up his arse?' spoke up the muggle

'Shut your mouth you repulsive unworthy muggle! You don't deserve to even stand beside me I swear if I had a wand you'd be begging me to…...'

'SHUT YOUR MOUTH!' Regulus turned towards an enraged Sirius 'either stay and shut your brainwashed mouth or go back home and play with Kreacher' he spat the last part out. For some reason Sirius hated the elf.

'You choose a muggle over your own brother, you're a disgrace to the family' with one last sneer towards the muggle Regulus left the park. As soon as he got home Regulus heard his mothers voice from the sitting room.

'Mother?' she looked up from a heap of parchment

'oh Regulus its you, where's your brother?'

'no idea' he spat venomously. His Mothers eyes widened.

'Regulus don't be disrespectful I didn't raise you to speak to me that way, Sirius would never ….'

'YOU OBVIOUSLY DIDN'T RAISE SIRIUS RIGHT SINCE HES GALLIVANTING IN THE PARK WITH HIS FILTHY MUGGLE FRIEND!' it came screaming out of his mouth before he could stop himself.

'What did you just say?' replied his mother in a low deadly voice

'nnnnothing mother iiit was a jjjoke' he stuttered out eyes wide in nervousness. She walked past him right out the front door and out of the yard. What had he just done? Minutes later the door burst open and his Mother came through dragging a struggling Sirius by the hair.

'BLOOD TRAITOR! VILE BRAT! BEFRIENDING FILTHY DISGUSTING NO GOOD MUGGLES…' she walked right past Regulus down the hall way and into father's private library. Regulus hurried towards the shut door pressing his ears to the door.

'YOUR WRONG HE'S GREAT AND YOUR JUST MAD BECAUSE…...'

SMACK! That was the first time Mother had ever really struck Sirius.

'SHUT YOUR MOUTH YOU TRAITOR WAIT TILL YOUR FATHER COMES HOME. YOU DARE DISGRACE THIS FAMILY?'

'What family? This family's a joke! I'm glad you found out now I wont have to pretend to listen to your bigoted views'

'CRUCIO!' all he could hear were Sirius's screams from that point. He had caused this. Those screams of agony and pain will stay with him for years to come because he knows caused it.
