Chapter 1:

"Hello Lilly." Severus tried, with difficulty, to hide his excitement at seeing Lilly again.

She lightly swatted his arm. "Stop that. You don't need to pull the stoic Slytherin act around me." She didn't get it. It wasn't an act. That's who he was, or at least, had to be. She just didn't understand. Why did he think that their friendship could ever work? "Don't go there Severus Snape! There's a lot more to you than that, I've seen it. You don't have to be emotionless to be in Slytherin." Oh yeah, that's why. He had forgotten that Lilly did understand. She somehow always managed to see past his house and see the good in him, even though he never could. Lilly always saw the best in people-even Potter and Black. That showed exactly good she was.

"How do you that I'm not just some random, emotionless Slytherin playing you for a fool?" Most people would see that as a legitimate question, considering that she was talking to a Slytherin. Lilly took it like a Slytherin. She knew that the comment meant that he was not playing her for a fool.

She turned her back to Severus. "You know, I was going to ask you to sit with me in my compartment, but if you've decided to be contrary today…"

"Sorry." Severus muttered. Then he sat down on the black seats of the Hogwarts Express. Lilly was his only close friend in Hogwarts, so he didn't have anywhere else to sit. He lived a lonely existence until he stumbled across her on a muggle playground one year. She caught his eye almost immediately. There was something about Lilly that made her different from all of the other muggles running around the park. He found out that his instinct was right when he saw Lilly do accidental magic. Immediately afterwards he casually walked up to her and explained exactly what she was doing and who she was. They had been friends ever since.

She smiled. "It's alright. I'm sure you have a lot on your mind."

For a moment they were silent. Lilly was looking out of the windows as the Slytherin green fields rolled by, or maybe she looking out at the endless azure sky. But Severus found something more interesting to him than the scenery, Lilly. Of course, when he realized this he shook his head and looked away. Why had he felt so oddly compelled to look at her? Was it her outfit? He had to admit that she looked pretty in the blue dress she was wearing.

Pretty. Even in his mind the word 'pretty' sounded awkward. He had never thought of anyone other than his mother as being pretty. Yes, some of his fellow Slytherins like Bellatrix Black, for example, were attractive, but not in the innocent sense that Lilly does

Suddenly Lilly interrupted the silence. "It feels so good to be back at Hogwarts! What about you Sev? Are you exited too?"

Severus snorted. "Hogwarts means putting up with Potter." That didn't mean that he didn't like Hogwarts, because he did. It was more his home than the little house on Spinner's End. Still, he didn't see the need to mention it because Lilly already knew all of that.

"Oh come on! There's got to be something you like about it!" Lilly still looked at magic with a childlike sense of wonder. Maybe it was because she hadn't grown up around it like he had. To her it was a miracle, but to him it just was. He could almost feel her excitement radiating off of her. Severus loved watching the expression on her face when she entered the great hall for the first time each year, although he would never admit it. Severus never really knew why it made him happy, except for books that said that's what he read friends do-they were happy for each other.

Severus decided to humor her because he didn't want to ruin her sense of excitement. "I suppose I am looking forward to the food." Lilly rolled her eyes. Before she could respond he added to his comment. "Then I suppose, there's potions with you." At this Lilly grinned. Severus was never really the affectionate type, so he knew that she would realize how much he valued her friendship from that comment.

However, her grin was gone, quickly replaced with a look of exasperation. What had he done wrong? He wasn't good with females, but he couldn't be that bad.

"What is it with boys and food? Next thing I know you'll be dragging to a Quiddich match!" While Severus smirked she groaned. He knew that she hated Quiddich, and while he wasn't particularly fond of it himself he saw it as a matter of pride, and liked to tease Lilly about it.

"I'll have to keep that in mind for when I blackmail you." She always forgot the second rule of Slytherin-know their weaknesses-both friends and enemies. Of course, it's not like Severus would ever use it. He trusted Lilly more than he had ever trusted anyone. Not that she knew that.

"You wouldn't dare." Her emerald eyes were narrowed and had a dangerous glint in them as she leaned forward, daring him to challenge her.

Severus's mouth slightly quirked upwards. "Of course I would. What kind of Slytherin do you think I am?"

"Slytherin or not, you wouldn't dare. You value your life far too much." Lilly was obviously held back a smile. She was having fun with this.

"Like you could out duel me." He scoffed. Then, unexpectedly, she wacked him up side the head. It didn't exactly hurt, but it caused him to rub the spot that she hit anyway.

"Are saying that I'm inferior?" The dangerous glint was turning more dangerous every second.

"If you choose to take it that way…"

"You're not the only intelligent person in the school, you know. I may not have invented my own spells, but I'm very good at the ones I do know." To an outsider it would look like they were fighting. To them it was just a game to pass the time. They were the only ones who could really understand it anyway. Someone like Potter could never really understand. Speak of the devil… James potter walked in. It was obvious that he had been listening and had just run his fingers though his hair so that he could show up when he believed that the time was right. Severus rolled his eyes. That was typical of Potter. He has no respect for privacy and he didn't make the vaguest attempt at hiding his arrogance or vanity.

"Is he bothering you?" Potter glared menacingly at Severus, who in turn looked at him cooly. Show no fear, because fear is weakness-rule number six of Slytherin house.

"You heard us…you were listening in!" Lilly stood up and Joined Severus.

Of course Potter flashed his signature grin-the one that made all of the girls swoon and all of the guys want to beat him to a bloody pulp. Personally, it made Severus sick.

"I was just concerned about your safety Lills. You're riding with a Slytherin-and not just any Slytherin. This is Snivellus. He's dangerous!" Severus could see Lilly grit her teeth. She hated it when James called herAt this Severus snapped.

"Leave Potter!"

"Why should I?" He narrowed his eyes. His normally blue eyes suddenly looked icey.

"I'll repeat it again because you're clearly too dim witted to comprehend what I'm saying. Leave now if you want to leave with your limbs still attached." The words were whispered slowly, but were just as effective as yelling.

"See? Now he's threatening me!" Potter pointed at Severus with frustration written all over his face.

"Go, or I'll join him." Lilly threatened.

"Fine." The boy's shoulders sagged and he left, sulking. Severus smiled at the expression.

Lilly sighed in exasperation as she and Severus sat back down in their compartment. "At least he had good intentions this time. Still, how is it possible for him to be this obnoxious without trying?"

"This is Potter we're talking about. Simply existing makes him obnoxious."

"True. Personally, I think Sirius Black just makes it worse. I'm convinced that he gets some of his brighter ideas from him."

He snorted. "You're implying that they have bright ideas. They're just arrogant troublemakers that take credit for other people's ideas. Everyone knows that Lupin comes up with their so called 'bright' ideas. They're not brilliant, they're adequate at best."

His friend cocked her eyebrow in amusement. "It sounds like somebody's-"

"Don't you dare suggest that I'm jealous of somebody like him!"

"Why else would you talk about him so often? Unless you're-" As fast as a snitch he put his hand over her mouth.

"Don't you dare finish that sentence!" Effortlessly she twisted his arm and he let go.

"Sorry. I just couldn't help myself." Lilly always enjoyed teasing him. At least from her it was a friendly sort of teasing-not like with Potter and his friends. The 'Marauders' as they called themselves weren't friendly-they were malicious. They took a sort of sick pleasure from other's people humiliation- like that time Severus was in the great hall and suddenly his nose was turned into a bird beak and his hair was turned into feathers. The entire school laughed at him-even lilly chuckled before covering her mouth and looking down in shame. It was a horrific experience that, unfortunately, were not an uncommon occurrence with James and the other Marauders around.

"I am not, nor will I ever be, anything like Potter!" Severus declared.

"Thank Merlin for that!"
