Disclaimer: None of it is mine!:( Well, apart from the characters you do not recognise from Harry Potter, those are mine.

Chapter 1

Never flirt with the girl you just dipped in pond water.

It was peaceful in the great hall on Monday morning, the whole of Hogwarts chattered quietly and even Death-Eaters-to-be on the Slytherin table were hexing first years good-humoredly. The ghosts floated merrily between tables and the Grey Lady could be seen actually in conversation with the Bloody Barron. The peace was shattered however, by a scream from the back of the hall. Everyone turned in shock to see a dark haired girl stomping between the tables, red in the face, completely drenched and shouting.

"YOU GROUP OF INSOLENT TOADS!" The girl was wearing a dripping white nightgown, which was embarrassingly see-through, her feet were caked in mud and she wore one fluffy slipper, which was trailing pondweed "You've taken it TO FAR this time!" She came to a furious stop in front of the Marauders. "How DARE you put my bed in the LAKE! It's bloody DECEMBER do you have any idea how FREEZING THE WATER IS?!" She yelled in James Potters face. She poked Sirius Black in the chest "What if I couldn't swim?! What if I'd just woken up floating round on my bed with the giant squid poking me and fallen off? WHAT IF ID DROWNED?! As it was I had to SWIM to SHORE without my WAND! What if a Grindalow had grabbed me? My fingers are Fucking BLUE!" She snatched a handful of Peters robes " Where is my wand you little THIEF?! You just don't take peoples wands when you're pranking them! That's low, even for YOU!" She finally turned to the group at large, scowling at Remus. "You group of idiotic bullies! Why can't you leave us alone! Don't you have anything less pathetic to do than messing with Slytherins?" Sirius Black smirked

"No, not particularly…" This was apparently the wrong thing to say.

"I've had enough of this bloody schools unfair preferential treatment of you stuck-up Gryffindor scum!" Professor McGonagall stood up, the word detention at the tip of her tongue but Dumbledore held up his hand to silence her, an amused twinkle in his eye.

"Let her get it out of her system." He told her.

"Your completely self-centered and proud! Your whole bloody house thinks your sooo much better than EVERYONE ELSE! You think the whole school revolves around Gryffindor, according to you, Ravenclaw are a load of snobby nerds, being Hufflepuff is a joke because only people who are too lame for the other houses get in, you don't even consider them rivals in Quiddich and the house cup and as for Slytherin, according to you we're all evil dark wizards who have to be hexed every now and then to be kept in check! You all think you're so perfect! Well. YOUR. NOT. Every single house has it's good and bad points and the fact people have been allowed to bully other students just because they come from the so-called bad guy house is an outrage!-"

"Miss Lay! Are you quite done yet?" McGonagall said angrily.

"No." Sara shot at her, irritated, the students tittered. "-You marauders have crossed the line! I'm going to make you sorry you ever met me!-"

"Miss Lay!" McGonagall said more forcefully.

"I'm not finished yet!" She yelled causing outright laughter from the other tables. "-It's time someone taught you group of toe-rags a lesson! You just WAIT!" Sirius smiled charmingly.

"Calm down honey," he looked at her several inches south of her face. "Why don't we sort this out some other time, maybe over a couple of butter beers?..." He asked completely unashamed.

"Ac-Accio wand!" She shouted.

"They've locked it in James truck, it's not going anywhere…" Remus admitted from behind a charms textbook.

"So, what do you say, sweetheart?" Sirius asked with a wolfish grin, winking suggestively. Sara flushed and let out a strangled sound, her hand twitched to behind her ear where she usually kept her wand. Picking up a pitcher of pumpkin juice she emptied its contents on Sirius Blacks elegant black hair. He spluttered, outraged, wiping the thick orange liquid out of his eyes, glaring.

"50 points from Slytherin, Miss Lay! And detention every Saturday for a month, 4.00 pm! Boys, for endangering the life of another student 20 points from Gryffindor –each! Detention every Sunday until i inform you otherwise 4.00 pm!" Sara let out a disbelieving sound "- Sirius Black, a further 30 points for lack of respect for the opposite sex you will also join Miss Lay in detention for the rest of the month!" Sirius lost his smirk rather quickly. "Now, Miss Johnson," A Slytherin girl stood quickly worried about receiving a tongue lashing, "please escort Sara Lay to Madam Pomfrey before she develops pneumonia." She hurried her friend (who was decidedly blue) towards the doors.

Sara's P.O.V:

I spent a whole week in the hospital wing with a chest infection. An entire week! I'm studying for N.E.W.T's, I can't afford one week. On the day before I left I was sat in my hospital bed eating Bertie Botts every flavor beans with my best mates Katie Johnson and Severus Snape. Katie was stretched languidly across the bottom of the bed while Sev sat in a chair he'd pulled up by the bed eating a sugared mouse with a troubled expression.

"I just don't think you should do it," Severus said carefully.

"I don't see why not!" I snapped throwing a bean to Katie who caught it in her mouth with a grin "They've had it coming to them… Anyway I thought you of all people would be happy! We hate the marauders, don't tell me your going soft on them." His face twisted into an ugly snarl.

"Don't be ridiculous. Of course I hate that band of flee-ridden mongrels and mudbloods," I shifted uncomfortably I'm a half blood like Severus but my family don't share the blood-purity views typical of Slytherin, but in this day and age its best to keep that particular fact quiet. "Its just there's a reason why they're the ones who run around hexing people and were the ones being hexed!" My eyebrows knitted together,

"What are you trying to say?"

"He's telling you not to bite of more than you can chew." Katie sing-songed from the bottom of the bed catching another bean between her teeth.

"Exactly, thank you Katie, if you prank the marauders they'll prank you three times harder, they'll never leave us alone. I say we just keep our heads down and hope they forget about us for a bit."

"Oh for gods sake Sev! Like they're just going to forget about us after six years! Don't be so meek it really doesn't suit you, have an ounce of dignity and be brave for once in your life! Imagine there faces if we pranked them…" I basked in the glory of the image for a second before taking a huge bite of a suspiciously brown bean, choking and spitting it out retching and coughing "-Urgh! I don't even want think what flavor that was! -" I spluttered as Katie patted me on the back laughing herself stupid. Even Sev was smirking from behind a chocolate cauldron. Madam Pomfrey burst in fussing.

"What is the meaning of this? She is meant to be getting rest Miss Johnson, I don't see what's so funny!" I giggled with a wide smile,

"I'm okay Miss, sorry about the noise…" As Madam Pomfrey turned on her heel she flounced of muttering about noisy students and ungrateful pests, her dramatic exit was somewhat marred by the fact that she stood in the brown goop I'd spat on the floor on her way out. Katie caught my eye and raised a perfect black eyebrow, we both stifled giggles as I turned back to Severus.

"…As I was saying it's a bad idea Sara, I wont pretend I wouldn't like to see them knocked down a peg or two, but you shouldn't be the one to do it…"

"I don't care. They charmed my bed. Into. The. Fucking. Lake. I'm sooo up for revenge right now, I could write a song about it!"

"And as much as we would simply love to hear it, Severus has a point, why us?" Katie pointed out.

"Why aren't you on my side?"

"See! Katie agrees with me. -Don't you Kate?" Sev looked at her to back up his argument.

"Potter and Black will bloody own you…" Her face twisted into an evil smile, eyes twinkling mischievously, "…And it will be hilarious!" Sev groaned and put his head in his hands as we giggled and high-fived.

"Common Sev, lighten up, It'll really brighten up our year." She pointed out. He looked up skeptically, hair stuck up at weird angles. I sighed.

"And maybe they'll be so busy avoiding humiliation and trying to kill me they forget to pick on you?" This seemed to cheer him up and I grinned, "You are such a Slytherin!"

" You say that as if it's a bad thing!" Katie snorted.

"Never!" We cried. All three of us brandish whatever we had to hand (a box of beans, pumpkin juice, and half a chocolate cauldron) we knocked them together, sloshing pumpkin juice on the bed,

"To operation Prank The Marauders!" Sev and me exclaimed.

"And to Sirius Blacks arse!" Katie added much to our outrage (seriously Snape practically went purple). I chucked a bean at her snickering as it bounced of her head.

"We hate him remember! No time to contemplate his –admittedly gorgeous- arse!" Sev was looking at us as if we were insane "...Hey! Wait! Give that back! –I think that one was Strawberry!"
