Eileen's Boy

Sitting in their own compartment on the Hogwarts Express after leaving James and Sirius, Severus finally had Lily all to himself again.

"I don't like that boy. He's a pig, how dare he make fun of you!" exclaimed Lily. "Are all wizards that mean?"

"No, just spoiled brats like him," he replied. "I'm excited for the sorting. I really hope we're in the same house!"

"Me, too, Sev. I don't know what I'll do if we're not. I'll be so lost without you."

Severus beemed at the thought of her needing him. "Let's promise that we'll always be best friends, no matter what!"

"Okay," Lily said sheepishly.

He watched her walk trembling toward the stool, and almost as soon as the Sorting Hat touched her red hair, it called out, "Gryffindor!" Severus groaned. He knew he'd be in Slytherin, he just knew it. And sure enough, the hat placed him in Slytherin and he watched Lily's sad face as he walked toward the table on the other side of the Great Hall.

Severus and Lily's first lesson together was potions, and they made sure to sit next to each other. Unfortunately, James and his friends were in their class, too, and they chose to sit right behind them.

"Hey, Snivellus, try washing your hair before you come to class next time!" James taunted. "Maybe in here, you'll learn to make a potion that'll keep you clean!"

"5 points from Gryffindor, young man," said a voice from the back of the room. "And on your first day in my class - what a great first impression. Well, at least you've got spunk." The teacher walked to the front of the classroom. "Hello, class. My name is Professor Slughorn. Now, every one take out your books, and we'll try making our very first potion! The person seated next to you will be your partner, just to make sure you get all of the ingredients and instructions correct. Make sure you double check everything with your partner."

As the professor explained a little about each ingredient they would be using, Severus and Lily got to work. Their potion was ripe on its way. Slughorn walked around the room as all the uncertain students mixed and poured. He frowned at James and Sirius, their potion looking more like a vat of mud than anything else. But as he passed Lily and Severus, he smiled.

"Oh, very good, very good! Your potion is the exact shade of teal it should be! You two seem to have a knack for this. 5 points each to Slytherin and Gryffindor!"

Potions was the only class that Lily and Severus had together, and so it became one of their favorites. They quickly excelled far beyond the rest of the class, and Slughorn was giddy with excitement every time he passed their cauldrons, whether they worked as partners or alone.

"Lily, Severus, I want the two of you to join me for a little get-together I'm having next Saturday. It'll be loads of fun, just you wait." He handed both of them a slip of magically embellished paper that read:

The Slug Club

A fun way to connect with the brightest kids in the school!

The first meeting is to be held in Professor Sluhorn's office next Saturday at 10 o'clock.

I hope you can attend!

"Do you want to go, Lily? I'm not really sure if I want to," Severus said.

"Well, I sort of want to. I mean, we'd get to see each other more often, wouldn't we?" reasoned Lily.

"I'm definitely going if you are," he said. Lily beamed at him, and Severus turned more than slightly pink.

When Lily and Severus arrived in Slughorn's office at five minutes 'til 10, they realized that they were not the only ones to get an invitation. There were a couple students from Ravenclaw, Slytherin, and Hufflepuff, and to their dismay -

"Hey, Snivellus, how come you got an invitation?" Sirius remarked. "I thought you needed to be grease-free to get in here?"

"Hey, Lily, why'd you come with Snivellus?" said James. "I would gladly have walked you down here myself. Why wouldn't you want to show up with the coolest kid in Hogwarts?"

"Because, Potter, I'd rather be friends with people who actually have talent. Let's get out of here, Sev," Lily said, but just as she and Severus turned to leave, Professor Slughorn bounced through the door.

"Now, now, not leaving so soon are we?" Slughorn conjured a large table with a feast set upon it and enough chairs for all the students. "Seems we have a rivalry on our hands! A little competition can be a good thing. Go ahead, everyone dig in!" As the students all sat around the table, he sat himself in a large overstuffed chair in the corner. "I thouht we could all have a small meal and get to know each other better."

"Why aren't you eating with us, Professor?" asked one of the Hufflepuff students.

"Oh I already ate. Besides, I want today to be all about you kids."

Slughorn asked all the students about their parents and relatives in turn going around the table.

"James, growing up in Godric's Hollow, you must have some good blood in you. I've been hearing you are quite good at Transfiguration and you excel on your broom."

"My father bought me the best broom there is so I can practice all summer. He was a great Quidditch player, and I will be, too!"

"Hah, great confidence and spunk, boy, never lose that!

"Now, Severus, your mother is very gifted at Potions, and it seems she passed that ability to you! And your friend - Lily, dear, you have much skill. I can see the two of you creating masterpiece potions together in the future!" Lily and Severus looked at each other and grinned.

- - - - -

"'Masterpiece potions together' my foot!" shouted James as he and Sirius ran through the hallway. Sirius smirked. "How dare Snivellus get so close to her! He's going to get her all greasy. What!? WHY ARE YOU LAUGHING AT ME, SIRIUS?"

Trying hard to compose himself, Sirius looked James in the face. "You like her, don't you?"

"No! Never! Gross."

Sirius shook his head. James would admit it when he was ready.
