A/N: Remus sees Marlene for the first time and has his first official meal as a Marauder :D. This thing is turning out longer than I thought it would. I'm already at chapter 4 and I have just finished introducing all the characters. Maybe I could make the chapters longer (though I hate long chapters). On with the show.

Disclaimer: I do not own Harry Potter.

I had Arithmancy for my last class of the day. It was my favourite subject: the numbers, the probabilities, the predictions and the fact that it was challenging. Arithmancy never judged and it never lied. There was one right answer and I loved the feeling I got whenever I was right.

I was listening intently to Professor Vector as she wrote on the board, trying to make sure I didn't miss a thing, when someone tapped my elbow. "Do you have an extra quill? My nib broke."

I turned to the right and froze as I looked into the most friendly, brown eyes I'd ever seen in my life. The girl's short black hair framed her face perfectly as she gave me a wide smile. She held the broken quill up and repeated her question, "So, do you have one?"

I gave her a goofy smile as I handed her the quill in my hand, "Sure, you can have this one."

She smiled and said thank you before simply turning back to her notes. I dove into my bag, searching for another quill, only to realize all my others were left in my school trunk. So instead of looking like an idiot and asking back for my only quill, I just sat in class, half-listening to Professor Vector as I stared at the black-haired girl beside me.

I ran into Lily after class where she handed me a broody-looking Severus' shirt now coloured pink. "Here you are, my dear," she said. "Sorry it's a bit small. Sev is a bit smaller than you but he refuses to let me enlarge it."

I shrugged as I held it against my body. It would be a bit difficult to get it over my head but not too bad. "Thank you, I-" I began but then she hastily shoved me into the nearest bathroom.

"You're going to be late. They always have dinner together at 6:03," she shouted through the door as I changed.

With how carefree they seemed to be, I did't think being a Marauder had so many rules. Sirius was looking down the end of the Gryffindor table while James was listing them off from his head.

"... you can't come into the Great Hall without one of us beside you, so wait by the doors if you need someone. And you can only wear the sweater vest look once a week, so I guess you've used up yours today," James explained as he looked down at my vest over the pink shirt. "If you break any of these rules, you can't sit with us anymore. They're for your own benefit, really. We help each other out and give each other advice, so you wouldn't do anything without consulting the group first, right?"

"I wouldn't?" I asked, still trying to remember everything James had just said.

"Exactly," James said with a smile. "Same thing with the girls around here. There are certain things you need to know about each one before you try anything with them."

"Like them," James said, gesturing to Lily who was having a silent conversation with Severus across the room. "Evans is cute but she hangs around with Snivellus all the time, who is greasier than a stick of butter, thus making her unappealing. You don't want to stay around her or other girls may get the wrong impression."

Sirius then suddenly got up and walked across the room to sit next to a pretty Hufflepuff girl, leaving the three of us alone.

"So, do you have your eyes set on any girls yet?" James asked.

The image of the smiling girl from Arithmancy flashed into my mind as I looked between James' and Peter's inquisitive face. "There's this girl who sits next to me in Arithmancy with short black hair and brown eyes. I think she was in Ravenclaw," I said.

"Marlene!" James said. "No, you can't fancy Marlene! That's Sirius' ex-girlfried, the one he really fancied."

"They went out for an entire year, the longest of all of them," Peter added while he shook his head.

"And he was devastated when they broke up after our DADA exam," James said.

"But wasn't he with Mary at that time as well?" Peter asked.

"That's not the point, Pete. Remus, ex-girlfriends are just off-limits to friends. It's part of the bro-code." Then he leaned in and said, "I won't tell Sirius about you and Marlene. It'll just be our little secret," James said as Peter nodded along with him.
