All HP characters are the brain child of J.K Rowling who is an extraordinary writer and who thankfully does not take offense to those of us who like to mess with her world.

While Calisto had been flying she had also been thinking. Thinking about her father and Sirius Black. There were very few things in this life that made her fathers eyes shine and it was clear to her that Sirius was one of those things. When he came back from Hogwarts he seemed to have had a great burden lifted off his shoulders and it wasn't just the fact that he could now tell her about the years at Hogwarts he so cherished. There was something else hidden there and it was only because she had lived with him most of her life that she could see the conflicting emotions that bubbled beneath the calm exterior.

It was obvious that Sirius had no idea she existed until he had trotted in their door. Cali had spent her time outside wondering why Remus had not told his friend. For a reason that she was just beginning to decipher Remus had not wanted to lead Sirius to believe he had a daughter, but he would also never divulge Cali secret without permission and Cali had not given it. Which was why she was now sitting in front of the ex-convict wondering how to proceed whilst watching him devour the sandwiches she had made.

He hadn't said a word to her yet and had followed her silently into the kitchen and only nodded when she asked if he liked bacon. He kept shooting her what she had begun to call the crazy man stare. He would mutter under his breath a little then shoot her the crazy man stare and go back to his sandwiches. It was a little unnerving. The whistle of the kettle broke her silent musing and she moved over to the bench to pore them both a cup. Deciding that she didn't want to try and guess how many sugars he wanted if he was only going to shake or nod his head at her she made her own then plunked the sugar milk and his cup down in front of him. That won her an amused look which was quickly turned into the crazy man look but she had seen the other already and guessed his game. The bugger was trying to unnerve her! She had news for him, she hadn't lived with a werewolf all these years to become startled by some demented ex-con. O.K, maybe she was a little concerned that she was alone with a man who had spent the past ten years with nothing but the worst of his memories but she didn't think that was unjustified. Remus Lupin may have strange tastes in friends but they were all harmless and there was no way he would leave her with him if he was anything but.

Calisto glared back at him so they were locked in a staring competition, she narrowed her eyes in a way she had seen one of her teachers' do and with a disgruntled huff Sirius broke contact. Cali grinned triumphantly but when Sirius looked back at her she schooled her features into a superior looked that had always irritated LeSaux. Sirius rolled his eyes and set about dumping more sugar in his tea then the human body could possibly handle. Well her father told her he was hyperactive in his youth, maybe someone should have monitored his sugar intake. Resting her elbows on the table Calisto wondered how the two of them became such good friends, they were so very different but maybe that age old saying that opposites attract was true in there case. Taking a sip of her tea she wondered if it would be worth telling him herself or if she should just let her father do it. First things first though.

"You like my dad don't you."

It wasn't really a question

Sirius looked startled but Calisto gazed back at him and the expression on his face was clearly saying, "She's not asking what I think she's asking is she?"

"We've been friends since…"

"That's not what I mean"

Calisto interrupted him

Sirius put down his tea and leaned back in his chair staring at her. He inclined his head in a very canine like gesture and seemed to be studying her.

"Do you mean am I arse-backward in love with him?"

That was once again meant to unnerve her but she continued to stare him down. They stayed like that for a moment until a smile touched Sirius lips.

"You really care for him don't you?"

"Someone has to, Lord knows he won't do it himself"

She replied quietly

Sirius shook his head sadly

"Ol' Moony still beating himself up over everything. Don't worry, I won't be here long I don't like seeing him in pain either."

That confused Calisto. Sirius thought he was causing her father pain? She noticed that Sirius was leaving the table.

"He misses you."

She blurted out. Sirius regarded her with a closed expression.

"He didn't know whether to be happy or sad when he came back from Hogwarts. He hated that it was Peter but he was ecstatic that it wasn't you. He felt it was his fault that Peter got away and that your name couldn't be cleared. He did that everything's fine look for ages but I could tell that it was tearing him up inside. When he talks about you he gets this spark in his eyes, he hardly ever gets that anymore."

Sirius looked like he had been presented with the key to the universe. Cali was humming inside, she couldn't believe that the two of them had never done anything about feelings that were so obvious it had only taken one brief meeting between the two to for her to realize it. "Foolish, foolish men" She mental scolded them. There was one thing that bothered her though. Could she trust Sirius with her fathers' heart? He did declare that he was in love with him but was that enough? Looking at the expression on his face her heart melted. This was no longer that young man that her father had described, he was more likely to treasure and fight for what he had now and not take the foolish risks he once had, yes she could trust him. Then a shadow crossed Sirius's face "Oh no you don't" She thought, what could possibly be wrong.

"What about you?"

He asked softly

That threw Cali completely

"What about me?

She asked

"Oh I think it's great, you've both obviously wanted this for a long time and I just want Papa to be happy."

Sirius seemed only partly satisfied with her answer. He took in a deep breath but wouldn't meet her eyes.

"What about your mother?"

Calisto faulted and her expression instantly darkened. Looks like she was going to have to tell him after all. For a moment she considered making something up, some wild story about some trashy woman who seduced her father and then turned her back on him leaving him heartbroken and left to raise a child on his own. Or maybe the one where her mother had died in childbirth. That one always raised the least questions and was the one she had given the school. She sighed and looked at the vulnerable man in front of her, he really seemed to genuinely care about her father. He would have to know the truth. She leaned heavily into her chair and looked up at him.

"I'm not Remus Lupins daughter."

AN: Ok I lied, the next chapter will explain who she is exactly.
