A/N: Just to say, I've already written up to about halfway through chapter 4, the only reason I'm not posting everything in one go is to pace myself, I'm not the quickest writer I'm afraid so I'm going to have to ask for patience from you all. Thank you loads for the follows and positive reception I seem to be getting, and here's chapter 2, enjoy.

Chapter 2

I managed to avoid meeting Sirius around the castle or even at meals for the next two days but there was no escaping him in our Potions lesson on the Wednesday where we were sat next to each other. I did my best to ignore him for the first twenty minutes of the lesson with us both focusing on our potions. That was until we had to leave our potions to simmer for several minutes and he finally broke the silence.

"So, how long have you been an animagus?" I could hear a smirk in his voice as he prepared his ingredients for the next stage of the potion.

I froze when I heard him, cursing myself for letting him see me in that form. I quickly recovered myself before smirking back at him.

"About as long as you have. Padfoot," there was a challenge in my voice as I also prepared my ingredients.

"Touche. You know, you're far more like me than you'd like to admit," Sirius grinned at me now, taking a seat as he waited for his potion to be ready for the next step.

"What gives you that impression?" I asked cautiously, frowning at him.

"Well the whole animagus thing makes me think you're a bit of a rule breaker. We're both from pureblood families. You're a bit of a flirt too, you've got that Charlie guy fawning all over you and I'm pretty sure Joel has a bit of a thing for you," he continued to grin, glancing at my fellow Ravenclaw who was at the front of the classroom.

"I don't know where you're getting all that from, I'm just friends with Charlie and Joel. And I may break certain rules, but I'm far more subtle about it than you, I'm not some silly prankster," I rolled my eyes at him. I wasn't like him at all, I was certain he was just trying to annoy me even more.

"Being compared to me is a complement, after all I am so much better than everyone else," there was a twinkle in his eye and I could tell he was teasing me now.

"You'd be lucky to be anything like me," I smirked back, checking my watch and adding the next ingredient to my potion, stirring it magically with a flick of my wand.

"That's true, you are so much better than me, I positively worship the ground you walk upon," his grin spread across his whole face now and I tried not to laugh at his use of my own words.

I turned away trying to hide the fact that my face was betraying me with a small smile.

"Ah, she smiles! I thought you were impervious to my charms?" Sirius smirked, his eyes twinkling with laughter.

"Shut up. Idiot," I tried to glare at him, but it was rather weak as my heart wasn't in it.

"Knew you'd warm to me," he grinned to himself with satisfaction as he added some ground lavender to his potion.

"I haven't warmed to you. I just don't feel like gouging your eyes out anymore," I replied to him.

"That's close enough for me," he answered with a grin, making me laugh slightly.

I had to admit, I didn't completely hate him after all. He was still a pretentious git with a massive ego, but he could be amusing at times, and when he smiled it made you want to smile back, plus he was rather nice to look at. Not that his looks had anything to do with it, definitely not.

"So Rosa, now that you don't hate me, how about I take you on a date?" he joked, grinning at me as we packed up our things at the end of the lesson.

"In your dreams Black," I retorted, smirking at him as I put my bag over my shoulder.

"Oh you definitely will be," he gave me a suggestive look.

"You're such a perv," I elbowed him in the ribs, rolling my eyes at him as we walked out of the classroom.

Sirius just laughed at that and I couldn't help the smile that worked its way onto my face.

"Fancy getting first pick of the food for lunch?" Sirius' eyes twinkled with mischief as he hesitated at the steps that would lead up to the Great Hall, looking down the corridor which I knew would lead us instead to the kitchens.

"If you're going to try impressing me by taking me to kitchens which we're not supposed to know about then I'm going to have to disappoint you," I smirked back at him as I walked down the corridor towards the kitchens without hesitation.

"Remind me again why you're not in Gryffindor?" Sirius grinned at me, catching up with me just by extending his long legs.

"I've got brains remember?" I winked at him, matching his grin with my own.

"I have brains, alright," he pretended to look offended, an over the top pout on his face.

"Perhaps, but I actually use mine," I tapped my head, smirking at him.

"Ouch, you wound me," he put his hand to his heart but grinned none-the-less.

"I wish," I chuckled, stopping in front of the portrait of fruit concealing the kitchen entrance.

I reached my arm out and tickled the pear to open the door. It swung open and I stepped back, letting Sirius go through first before following myself.

"Miss Lake, what a pleasure to see you again! What can I get for you? We have your favourite feta pie, or I can make an omelette for you?" a female house elf came rushing over to me with a massive smile as another one pulled a stool up for me by the fire.

"It's lovely to see you too Minny. Now I won't have you putting yourself out for me, I'll just have a slice of that pie if you don't mind," I smiled back at the little elf, sitting down on the stool as Sirius seemed stuck in place gawking at me.

"So I guess you come here a lot huh?" he looked impressed now as he sat down on a stool next to me that the house elves had put there.

"People can be annoying to deal with sometimes, and the service here is excellent," I grinned as Minny brought a tray over to us with a slice of pie for each of us and two glasses of butterbeer.

"Thank you Minny, that's very kind of you," I smiled again as I took the food and drink from the tray and Sirius did the same.

"Can Minny get Misstress Lake or Mister Black anything else?" Minny's huge eyes looked up at us with a smile.

"No, that's all thank you," I was rather fond of the small elf and smiled after her as she hurried off to prepare more food.

"Butterbeer? They bring you butterbeer? I didn't even know they had butterbeer in the castle. Are they hiding some fire whiskey in here somewhere?" Sirius looked incredulously at me, taking a sip of his butterbeer with a grin.

"You'd be surprised how far being nice can get you, might want to try it some time. And they don't have any fire whiskey…I checked," I grinned a little, taking a bite out of my pie.

"Well aren't you a right little rule breaker? Mmm, what is this thing? It's delicious," Sirius' eyes lit up as he tried the pie, taking a rather large bite.

"I know right, it's some muggle pie with feta cheese, it's Greek I think, I'm in love with it," I grinned as I took another bite of my own pie.

"I swear muggles have all the best foods," the older Gryffindor frowned as he continued to stuff his face with the thing.

"They do, but we have better drinks," I chuckled, washing some of my pie down with a sip of butterbeer.

"I have to agree with you there, can't beat a few shots of fire whiskey or a bottle of elf wine," Sirius agreed, his eyes twinkling mischievously.

I just chuckled at that, eating some more of my pie, while Sirius continued to devour his own.

We were both finished fairly quickly and I stood up, taking my dishes to the massive sink at the other end of the kitchen. Sirius however decided to be lazy and banished his own dishes into the sink on top of mine with a flick of his wand and a cocky look on his face.

"Are you trying to impress me with wordless magic now? Because again, I'm going to have to disappoint you," I grinned at him, taking my wand out and flicking it so that his stool toppled over, causing him to fall to the floor, landing on his ass.

"Now that was uncalled for," he narrowed his eyes at me, huffing as he pushed himself off the floor and brushed himself off.

"Well someone had to put you in your place," I smiled sweetly, walking back over to him.

"I don't like you anymore," he decided, turning round and walking towards the exit.

"Feeling's mutual," I retorted, following not far behind him.

Sirius chose not to answer me as he opened the portrait back out into the corridor, not stopping to see if I was following. I chuckled at his sulky behaviour, following behind him back up towards the Great Hall. When he continued to ignore me when we reached the massive room I rolled my eyes.

"Have I injured your oversized ego by being mean? However can I make it up to you? I know, how about I go play fetch with you? I know how easily entertained dogs can be," he snorted at that, unwillingly grinning at me, shaking his head.

"You're just full of insults aren't you?" he chuckled, stopping by the doors as we entered the Great Hall.

"Only for my favourite puppy," I winked at him, a playful smile on my face.

"Oh I'm your favourite now? I thought that was reserved for Charlie?" he returned the look, glancing over at the Gryffindor table.

"Well now I have an actual puppy. Just don't go telling him, might hurt his feelings," I answered.

"Oh of course, wouldn't want to do that now would we. I still say he fancies you," Sirius replied, a knowing look on his face.

"Whatever. I'm going to meet Elody and go to Transfiguration. See you later, pup," I grinned at him as I headed towards the Ravenclaw table.

"Not before I see you, kitty," he retorted, causing me to groan and shake my head, an amused look on my face.

"What happened to hating Sirius Black's guts?" Elody asked me with a bemused expression when I reached her at the Ravenclaw table.

"It was far too tiresome. It's much more fun outsmarting him and making a fool of him," I grinned at my best friend as she got up from her place.

"I really don't understand your logic," she shook her head, laughing.

"Don't worry, neither do I half the time," I laughed back, linking arms with her as we left for Transfiguration.

A/N: So I realise that I gave the impression from the summary that Rosa and Sirius wouldn't get along for a while and they seem to be becoming friends fairly soon in the story, but just so you know it won't be all plain sailing, but they are going to be somewhat friends for now. Hope you liked it and chapter 3 shall be up at the beginning of next week.
