Slytherin Siblings

Chapter 1: Dysfunctional Family Ties That Bind

"Lucius that had better be my letter; I've been waiting all summer for it." Mahala stepped back so that the barn owl could safely land on the chair beside her.

Lucius paused for a moment; what kind of letter could she be speaking of? Then it hit him, she had been waiting for her Hogwart's letter. Though he was thirteen years her senior, he could be unbelievably slow sometimes. "Mum and Dad would be so proud; you getting your Hogwart's let..."

She cut him off." Not Hogwart's, they've sent me five letters in the last two days. I want to go to Durmstrang, or maybe that school in Canada. I've heard that their students come out really evil; I want to learn stuff like that." Lucius couldn't have been prouder; his little sister who he had raised for the last two year was the picture of perfection. "I want to be super powerful." She looked at the owl, and before seeing the stamp on the envelope she knew that it was another blasted letter from Hogwart's.

"For 600 years Malfoys have been going to Hogwart's. Look at how I turned out." Mahala refrained from rolling her eyes; she knew he wasn't their poster boy for academic excellence. He was good, but that wouldn't be enough, not for her; she knew too much magic already.

Lucius' eyes glazed over with anger from her disrespect of his alma mater. "The Dark Lord went to Hogwart's, and so will you! End of discussion!" What he did not tell her was that she was all he had for left for family and he would not have her wandering around some unknown countryside, away from his ever watchful glare.

Though mildly upset at being told what to do, Mahala feigned anger and stormed from the room. She supposed she could be happy at Hogwart's even before her brother demanded she go, but it was always best to let him think that he had won.

Six Years, Four Months, and Five Days Later

"You are not going out looking like that, and at this time of night! What kind of girl goes out at this time of night?" Lucius was livid.

Severus thought Mahala looked good; her friend on the other hand, was dressed like a tramp hoping to catch Lucius' eye. All Mahala's friends did that.

Mahala looked at him as if he had seriously lost it, though she knew that he would react this way. "It's eight-forty five," she paused; her sarcasm was only angering him more. "And I'm seventeen." Pause, she knew what he was thinking. "I was already punished for that at school! Come on, its Christmas break," she pleaded

"I told you that you would be grounded for Christmas break! That stunt you pulled cost you your Head Girl title." At the mention of this incident Severus looked down and massaged his temples. He was only in his second year as Head of Slytherin and already Mahala had made him question his acceptance of the position. How she was ever made a prefect and subsequently Head Girl was anyone's guess. Her last charade was the breaking point for Dumbledore. Professor McGonagall had caught her a month earlier out on the town doing shots with some rather seedy guys in their thirties. Severus was still unclear as to how she managed to get off campus and he knew Minerva was keeping something from him. Mahala's made no excuse for her behavior; Slytherin girls just want to have fun. Seriously, all that study for the N.E.W.T.s and no party time.

Mahala had been in detention every day for the last month, there was no way she was going to submit to his patriarchal bullshit. He could be so controlling. She would have to pull out the big guns for this one. "Well I guess if I stay home I'll have plenty of time to tell your wife about you sleeping with my high school friends. You know, she's been really suspicious lately, asking me all kinds of questions. I'm starting too really like her as a person and I feel like I'm..."

"SHHH!" How dare she say that when Narcissa could be home at any time and in front of this fine specimen that he had only five minutes earlier committed to seducing? Severus was quite aware of his friend's pervy behavior, but he was also quite sure that Mahala was baiting him. Bringing her friends by, seductively dressed, knowing that her they were hot for her brother. He had fallen prey to her evil plan the previous summer when he shagged one of two recent graduates of Hogwart's that she had brought by on a Saturday night. The girl was complete rubbish in bed, and after wishing he could obliviate his own memory, he decided upon obliviating hers. What did catch his attention was the fact that Mahala had disappeared for the whole event. Where had her disobedient, manipulative self gone, he wondered. With her penchant for trouble, this was definitely worth investigation.

"Well, if you're going to go out dressed like that then I demand that you put on a heavier coat, and mittens, yes mittens." Lucius paused; Mahala submitted to his demands like a pouty child (knowing that this would give him the impression that he had won the argument); Winnie (the friend) wanted Lucius even more after showing fatherly concern; Severus wondered what was wrong with this picture; no, he knew what was wrong with this picture. "And...Severus and I are going with you!"
