Author's Notes: I decided to make the Malfoys related to the Blacks through the mother, there isn't any mention of the mother's family tree in OOTP (that I remember) and anyway, I am inserting a character so…it's artistic license, right? This starts during the summer between Harry's 4th and 5th year at Hogwarts. It's my first fan fiction story so please review and let me know what you think!
Disclaimer: It's slash (two men) eventually so if you don't like it, please don't read it! And I don't own any of the characters, except for Cassius Malfoy because I made him all up. And I am making no money from this.
Chapter 1 Discovering Relations
Harry had been at Grimmauld Place for a week when there was a flurry of excitement about a dinner guest who was coming that evening. On his way to the kitchen for lunch he overheard Mrs. Weasley talking with Dumbledore. "Cassius Malfoy? The auror?" Molly Weasley sounded awed and surprised as she spoke with Dumbledore's head in the fireplace.
"He's a member of the Order, and something more. I think it's time certain introductions were made." Dumbledore answered. "I've told him to be there at 7 o'clock."
Harry entered the kitchen and sat down for lunch. Ron and Hermione followed him.
"Cassius Malfoy, an auror? And a member of the Order? But I thought all the Malfoys were dark wizards." Hermione asked.
"Well, he's one of the best aurors in over a century. They say if he had been around before…well, he's very good at his job, from what Arthur has heard at the office." Mrs. Weasley answered.
"Dad says he never talks to anyone." said Ron.
"Well, he talks enough to get suspended from his job twice." Mrs. Weasley answered.
"For doing what?" Harry wondered if Cassius Malfoy really was a dark wizard.
"I'm not sure, I just know he can't have his wand in staff meetings anymore, according to Tonks." Mrs. Weasley set the plates down on the table. "Now, where are Fred and George?"
CRACK The twins apparated right behind their mother.
Mrs. Weasley had started preparing supper and Harry and Ron were playing a game of wizard chess next to the fire with helpful (and sometimes not so helpful) comments from Remus and Sirius. Hermione and Ginny were each reading and Fred and George were upstairs, up to something, no doubt.
Mad-Eye Moody walked into the kitchen at Grimmauld Place followed by a tall, silver-blond man whose eyes scanned the room quickly and then started an examination of the floor. He wore muggle clothing, a long black jacket with a black shirt underneath and black pants. His hands were in his pockets. His resemblance to Lucius Malfoy was uncanny. Harry took a deep breathe and reminded himself that this man was an auror and a friend of Dumbledore's, not a Death Eater.
Moody started the introductions, he went around the room naming everyone. Cassius Malfoy didn't move or remove his hands from his pockets. He nodded at Mrs. Weasley, Ron, Hermione and Ginny. When he was introduced to Harry he looked right into Harry's eyes. There was something familiar about his eyes but Harry couldn't place it, they weren't like Draco's or Lucius's. Harry waited for the inevitable glance upwards towards his scar but Cassius Malfoy didn't look, just moved to the next person which was Lupin. Harry, who was still watching to see if Cassius would glance back at him, noticed a muscle clench in Malfoy's jaw as Moody introduced him to Lupin. Malfoy's only other response was the same small nod as before. "And you remember your cousin, Sirius Black." Another nod. "Cousin?" Harry couldn't help blurting out, he looked over at Sirius.
"I told you, Harry, all the pure-blood families are related in some way." Sirius said looking at Cassius with a glare. "My mother was his father's sister. Her maiden name was Malfoy. He and his family used to spend every Christmas here." Sirius's expression made it apparent that those memories were not treasured.
Kreacher crept in the doorway and suddenly bowed low to Malfoy. Malfoy looked down, he seemed startled but the expression came and went so quickly that Harry thought maybe he had imagined it. "Master Cassius, it is so good to see you again." Under his breath he continued. "Not like these mudbloods and traitors." Louder, he continued, "Please, Master Cassius, Mistress would like to say hello."
"Of course." Malfoy's voice was smooth and silky, Harry was strongly reminded of Lucius Malfoy and had to remember that he wasn't in the graveyard surrounded by masked Death Eaters, that he was safe.
Malfoy turned on his heel and went back up the stairs towards Sirius's mother's portrait.
The room was left silent. Sirius moved towards the door and muttered something. Suddenly, the voices from the hallway were as clear as if they were in the room.
"My dear Nephew Cassius, it is so good to see you again." Mrs. Black sounded happy, she wasn't screeching, such a change from her normal manner.
"And you, Aunt Black." The voice was emotionless.
"How is your brother? His family?"
"They are all well. Draco will be starting his fifth year at Hogwarts soon."
"And he's in Slytherin?"
"It's so good that Lucius saw fit to have an heir to carry on the family name. Especially since you… well…I do wish the house of Black would continue. If only Regulus hadn't died…."
"Your husband has been living here for some weeks, are you aware of that?"
Harry looked at Ron and Hermione, they were confused – Malfoy's husband? Living at Grimmauld Place? Harry looked around the room, Mrs. Weasley seemed just as confused as he by Mrs. Black's comments. Sirius was looking at Lupin who had a slow blush spreading on his face. Harry caught Ron and Hermione's eyes and tilted his head towards Lupin. They both looked and quickly looked back at each other with questions in their eyes.
"I do hope Sirius won't attempt to seduce him away from you, he never was honorable." The scorn dripped from Mrs. Black's voice.
"They were friends at Hogwarts, Aunt." The cool voice answered.
"I apologize, Aunt, but I must return, I do not wish to seem rude to my Cousin."
"You always did have such nice manners, he doesn't deserve your consideration."
"My father taught me well."
"My dear brother…may he rest in peace."
"Come visit me again soon. I love you, Cassius."
"And I you, Aunt."
