AU. Maurader-era. Lily/Severus for the most part.

This is just my take on a plotline that was suggested at.

"Get lost, Potter," Lily Evans said, loud enough for the entire hallway to hear.

It was just after Charms class, and the corridor was full. James Potter had picked this time of the day to ask Lily on a date, thinking there was no way she would refuse him with such a large audience. Apparently he was wrong.

"Oh, go on, Evans. Just one date?" James begged.

"She said no, Potter. Or do her wishes mean nothing to an outstanding Quiddich player such as yourself?"

James Potter spun around so fast that he was almost a blur and his upper lip curled in disgust. For in front of him was the one person he hated more than anyone - that slimy, sneering Severus Snape.

James and Severus had been enemies from the moment they set eyes on each other, but for some unfathomable reason, Lily seemed to want to be friends with Snape. This bothered James, mainly because Snape got to spend more time with Lily than he did, but also because he was kind of scared of Snape. There was something about the boy that meant he had few friends because he terrified most people in their year, as if they knew something bad was going to come of him, almost like he was ... evil.

"Did you hear me, Potter? I told you to get lost. And I mean it. If you come anywhere near me again, I will curse you into oblivion." Lily insisted, shoving James as hard as she could and storming past him with Snape drifting along after her, an odd half-grin on his face.

That smile bothered James almost as much as Snape waiting on Lily after her class did. What was he doing outside Charms anyway? Wasn't he in Transfiguration just now? So how did he get to the Charms corridor so quickly? They weren't in the same House, after all. He was a Slytherin while James and Lily were both Gryffindors... Then how did Snape get there so fast? Not even one of the secret passageways, the ones that nobody but James and his friends knew about, could make the journey that short...

A slap on the shoulder interrupted James' pondering.

"Better luck next time, Prongs." his best friend Siruis Black grinned at him.

James shook his head slowly. "Next time... Hey Padfoot, do you know where Mooney got to?"

Peter Pettigrew, or Wormtail as he was known to his friends, was standing slightly behind Siruis, glancing almost guiltily at the floor. James and Sirius were well used to Peter's odd behaviour, and Mooney's frequent disappearances. But this was different. Normally Mooney (known to the professors as Remus Lupin) disappeared during the night, and only at the full moon. It was noon and he had went to the bathroom earlier during the lesson and seemed to have forgotten to come back. That was very unlike him, especially considering he was the good one out of the group, the Gryffindor Prefect.

James shook his head again, trying to clear it.

Sirius was still grinning. "Nope."

"Nevermind. How about we skip lunch and go to Hogsmeade instead? We can always have something in the Three Broomsticks if we want."

Sirius grinned, "I like how you think, Prongs. And since we're skipping lunch, can we ditch afternoon class as well? It's only old Binns, he'll never notice."

The trio walked off, Sirius chattering excitedly about plans for what to do this afternoon. James was far away in his mind; he was still thinking about Lily Evans and her reaction to him. Peter walked slightly behind his friends, his guilty eyes never leaving the floor.
