A/N: Hey, this story just popped into my head one day and I had to get it out of there.
I don't own anything that is owned by Warner Bros. or J.K Rowling (what a genius hey?)
The bold texts throughout the story are the flashbacks to when Sirius and Harry are speaking to each other. (You'll know what I'm talking about here when you read it)
Hope you enjoy it :)

It was Harry Potter's fifth Christmas break, his first, when he started at Hogwarts School of Witchcraft and Wizardry when he was eleven years old. This Christmas, Harry, Ron and Hermione had come to spend Christmas at Grimauld place, the house of Harry's God-Father, Sirius Black.

Harry and Ron had spent the holidays in one of the empty rooms. After the Christmas celebrations, Harry was getting ready to return to Hogwarts, which was in many ways, his home. A week before Harry had a sudden surge of exploring the house of which his God-Father had spent the first fifteen years of his life in. Sirius Black was frowned upon in his family in his younger age. First being sorted into Gryffindor, when all of the past Black's had been put into Slytherin, then voicing his opinion about non- pureblood domination to his parents. Sirius ran away from his home in his fifth year of Hogwarts. He went to live with Harry's father, his best friend.

When Harry asked Sirius if he could search the house, Sirius could just looked wide-eyed and nodded numbly. Nothing in this house was worth looking at with respect or wonder.

Harry was hesitant at first, standing outside his God-Father's room. Sirius had agreed for Harry to search 'the house'. In Harry's mind, that statement didn't sound like it had any restrictions. So placing a hand on the door, he softly pushed it open. Harry couldn't help but to smile, if he hadn't had to live with his muggle aunt and uncle, if Harry had been raised by a magical family, this is what he imagined his room would have looked like. The walls of Sirius's room were covered in posters of various Quidditch teams and Gryffindor banners. Harry was so pleased; this looked like a genially happy room, one he would have lived in any day.

Harry walked into the room; happiness was all that he could feel. But as he looked closer at the walls, he noticed that they were damaged. Someone had desperately wanted these posters down. There were even scratch marks around some of the Gryffindor banners.

On the right side of the room there was a hole in the wall, Harry walked over, clenched his fist and then compared it to the hole, his fist fit perfectly inside. The happiness Harry felt, dimmed a little. He had always known that Sirius hadn't had the best up-brining that he could have asked for, but he had no idea that it was that bad. But then again, Harry, himself had almost put a few holes in the Dursley's house, His aunt and uncle

Harry peeled his eyes away from the wall and onto to other things in the room. His eyes skimmed the chests placed on the floor, the big wardrobe that stood next to the window. All of the things in the room had the Black family crest on it.

Harry's eyes reared to a stop as he looked at the bed-side table. Unlike everything else in the room, the table-top was cleared of everything, all except one thing.

Harry made his way over to the small table, and picked up the photo frame that was perched on top of it. The frame was gold and had a delicate pattern on it, but that wasn't what Harry was looking at. The photo in the frame was what caught his attention. Harry sat down on the bed and looked at it closer.

The photo, like all photo's and paintings in the wizarding world, was moving. It was snowing, and Harry immediately recognized the scenery of being the main street of Hogsmeade, the wizarding town just a few miles form Hogwarts. In the picture there was a single girl. Her light, straight, brown hair covered by a beanie. Her cheeks red from the cold, and her soft green eyes staring straight into the camera. She stood there laughing until she was hit with a snowball, which Harry assumed came from the person behind the camera. Her eyes turned wide with excited shock as she threw a snowball back, aiming for the photographer, but hitting the camera lens instead.

Harry jumped back to reality with a soft knock on the bedroom door. Harry looked up to see his God-Father leaning against the door frame, his eyes locked on the photo in Harry's hands.

Before Harry could apologize for being in his room and explaining himself, Sirius removed himself from the door frame and went to sit next to Harry, his eyes still on the photo.

After a minute's silence of both pair of eyes locked on the girl's face, Harry decided to speak.

"Who is she?" he asked, his eyes staring into Sirius'

"She was the love of my life, Harry." He replied with a heavy sigh.

"What's her name?"

"Her name was Charlie Emmanuel Potter... She was your father's younger sister."

Harry's eyes became so wide that he thought they'd pop out.

"This is my Aunt?"

Sirius' eyes went to Harry's for the first time. "'Was' was the key term in what I just said Harry."

"She's –" Harry struggled to get the word out, although he'd think that he should be used to it by now. "Dead?"

Sirius sighed again.

"My dad's sister. Then she must've gone to Hogwarts?"

"Charlie was a year younger than your father."

"Then she went to school with you - and Lupin - and my parents," he stopped, he remembered one name which he said with a bitter tone. "And Snape"

Sirius chuckled at Harry's tone. "Yes she did."

"But how did she-?" Harry had so many questions, that he was almost exploding from them.

Sirius let in a deep breath, and placed his hands on top of Harry's. "Let's start from the beginning, shall we?"

A/N: So what do you think? Please say something, even if you want to tell me that you don't like it.

I'm still trying to work out the proper storyline for this, so don't get angry with me, please, patience is the key.

Thankyou everyone :)
