Well this is my first Harry Potter story, so please tell me what you think!

Summary: At first, it was an accident. They hadn't known what talking to each other would do. Since they were in Slytherin and Gryffindor, it couldn't be good under any circumstances. Then, they began a game out of sharing quotes, trying to outsmart the other.

Disclaimer: I do not own Harry Potter or the quotes.

AU: Sirius got sorted into Slytherin.

Pairings: Eventually RL/SB and JP/LE

Rating may be changed later on.

If there are any specific quotes you want to see in here, feel free to tell me. I pretty much have the story planned out but alas, there are still a few gaping holes.

Fourth Year, Hogwarts

He had seen them more than once- been the victim of their pranks maybe twice but only when he was in a group, caught unaware. Yes, Sirius Black of Slytherin knew who James Potter, Remus Lupin, and Peter Pettigrew of Gryffindor were. They usually didn't play pranks on him. He was easily able to get around that. Potter stared at him frustrated, Pettigrew was scared of him, and Lupin… Lupin just smiled a smile that had no emotion, always ready with a counter spell. He never thought much of it.

Until the first time Lupin said something to him, two days after fourth year began.

"Watch your thoughts, for they become words. Watch your words, for they become actions. Watch your actions, for they become habits. Watch your habits, for they become character. Watch your character, for it becomes your destiny(1)," The quote refused to leave Sirius' mind. So what if he was picking on the Pettigrew boy? Everyone knew he was a Black. Blacks were respected- everywhere. Weren't Gryffindors- yes, the pathetic boy was in Gryffindor, Sirius snorted- supposed to be brave? He really wasn't anything of the sort.

Then that Lupin boy stepped in, inquiring Sirius' name.

"Why? So you can turn me into the teachers?" Sirius laughed. "But my name is Sirius Black."

"I won't turn you into the teachers, but for someone who so desperately doesn't want to be like his family…" Remus said. Then he said his damned quote. Now Sirius hadn't made it a secret about how he didn't care about the Black name or following in his family's footsteps, but he definitely hadn't pitched the thoughts to any Gryffindors.

He saw Remus walking out of the library and rushed up to grab him. He thought he was being quiet but then Remus turned, eyebrow raised.

"Can I help you with something, Black?" Remus asked, as if he hadn't muddled Sirius' train of thought for the past week with his stupid quote. Sirius glared and dragged the boy into another hallway, one where less people were likely to be around.

"Dragging me off to a dark corridor? Why, Black, I didn't know you felt that way," Remus smirked but it didn't really seem like something he would say. Sirius got the feeling that the Potter boy was rubbing off on him so he just ignored it, not that he'd deign to give an answer anyways.

"That quote- what the hell was that?" Sirius demanded. "You didn't just come up with that on the spot!"

"It was a quote, Black. Nothing more, nothing less," Remus said, amusement present in his eyes.

"That- you!" Sirius said frustrated, drawing his wand and holding it at Remus' throat.

"That's not such a good idea," Remus warned, any trace of amusement gone.

"You're a dreamer, Lupin," Sirius growled, pocketing his wand. "You think everyone can live in peace."

"I never claimed to think that," Remus said.

"You might as bloody well have," Sirius snarled.

"Why does that quote bother you so much?" Remus retorted. "Why would you be mean to Peter? You don't even know him,"

"You see things; and you say, 'Why?' But I dream things that never were; and I say, 'Why not?(2)'" Sirius snapped.

"Who wrote that quote?" Remus frowned.

"Figure it out," Sirius smirked. "You're certainly smart enough." The last thing Sirius expected was, three days later, for a tired yet smug Remus Lupin to drop a piece of parchment on his lap and whisper in his ear, "George Bernard Shaw."

"Dreams are illustrations... from the book your soul is writing about you,"-Marsha Norman

"What did he want?" Severus Snape asked distastefully.

"Borrowed potions notes," Sirius smirked.

"And you let him? Black, I question your tastes," Severus said.

"If I cared about your opinions, Snape, I would have asked for them," Sirius snapped, getting up to leave Snape's company. He had never been fond of him. He didn't even really consider him a friend but his parents were sure he'd get in with the Dark Lord and forced him to spend time with him. He heard laughter and recognized it instantly to be Remus Lupin's. He looked over and saw the other boy with his friends, smiling even though he looked tired.

"Next time, don't stay in the library all day, Remus! No wonder you're so tired and sick all the time!" James teased. "School's only just begun and you're already getting sick from all the dust these bloody things collect."

"Some people actually enjoy reading, James," Remus sighed. "And Lily is one of them."

"What were you looking up anyways?" Peter asked. Remus paused when he felt eyes on him, noticing the heir to the Black name and smiling with no emotion before Sirius blushed and looked away. He searched for his next quote, finally finding it several days later. Sirius was unaware of the effect the quote would have on Remus when he would read the dropped parchment on his lap, even though the game had only just begun.

"A dreamer is one who can only find his way by moonlight, and his punishment is that he sees the dawn before the rest of the world," –Oscar Wilde

Sirius hadn't stuck around to see the parchment drop to the floor, a pale and shaking Remus staring after him.

Did he know? Did Sirius Black, heir to the Black fortune, Slytherin, one of the most likely to become a Death Eater, know his secret?

And if he did, how did he find out?
