Chapter One: The Challenge

"Okay," Remus said, pulling a roll of parchment out of his bag. The Marauders were crowded in the last carriage on the Scarlet Train, headed for Hogwarts School of Witchcraft and Wizardry. "I did some research over the holidays and learned some new things that may help you land Lily."

James was suddenly all ears, which of course, looked perfectly ridiculous. He transfigured himself back and asked, "What?" Even Sirius and Peter looked up from their sweets with interest. "Go on," said James.

"The way it is- everyone has some sort of sensory trigger that puts them, shall we say, in a state of mind that-"

"They're horny?" suggested Sirius.

"Ready for action?" tried James.

"Well, yes," said Remus, blushing. "And like a love potion, where the smell is different for everyone, the trigger is different for everyone."

"So, you're saying I should force feed her a love potion?" James asked, utterly confused.

"NO!" said Remus quickly.

"That's illegal, you twit," said Sirius.

"It wouldn't be the first time we've done something against the law," Peter pointed out.

"You've got a point there, Wormtail," said James.

"Focus! All you have to do is find her trigger, so to speak, and you'll have her eating out of the palm of her hand."

Twenty minutes later, Remus and James made their way to the prefects' carriage, James for his very first time, and he was quite nervous.

They opened the door to find Lily already setting up inside. She looked up and saw Remus and began, "Oh, Remus, I'm glad you're here. I thought we'd start with the new passwords, I've only just received the owl, and then…" she trailed off, seeing James. "What's he doing here?"

"Actually, he's the one you should be talking to," Remus said.

"What?" Lily asked, confused.

"I'm the Head Boy," said James.

"Oh!" said Lily. "Well…oh!"

"Hey Lily," he said, helping her by filling goblets with pumpkin juice and setting it out for the prefects, "the guys and I were having a discussion, and you know how a love potion smell different for everyone?"

Lily looked suspiciously at her goblet of juice that she was just going to drink out of.

"No! I mean, Remus said that sometimes just a sound or a picture can do almost the same thing."

"Potter, does this have a point?"

Remus was in the corner trying not to laugh.

"Well, I was wondering what yours was."

"What's yours?"

"I'll tell if you will."

"I'll give you a clue, but only because you'll never guess."

"What is it?"

"It's a muggle song- I heard it when I was five, and it just made me go weak in the knees. I still don't know why… after all, I was only five years old…."

"If I guess it, will you go out with me? Just once!"

She looked at him amused. "Alright, Potter. If you guess it, I'll go out with you. Name That Tune."

The meeting had started. James and Remus sat in the back.

"That shouldn't be too hard… how many muggle songs can there be?"

"You're crazy, Prongs."
