** Chapter Three **

============

Lily and Ariella settled down at the Gryffindor table Sunday morning opposite James, Sirius, Remus and Peter, each of whom grinned at the girls smugly.

"Morning, girls," said James airily, pouring himself some juice. "How's your day been so far?"

"It's been all right," Ariella answered.

"However it's overshadowed by what we're going to do tonight," Lily added.

"You agreed," Sirius pointed out, about to shove some bacon into his mouth.

"I know that," said Lily smoothly, flittering her eyelashes and taking some toast of the pile, "but when I woke up this morning and remembered our deal I thought I must have been off my rocker last night."

"I repeat, you agreed," said Remus.

"Look at the git over there," said James, glaring over to the Slytherin table where Snape was sitting deliberately opposite Mirabelle Scarlett. "You know why we're doing this?"

"Why?" said Lily tonelessly. "Because you're going to be nice for once and put a bit of love in Snape's life?"

"As if," said James snappishly. "We're doing this because we want to confuse the slime ball. During the night our Mirabelle's going to be all over him. During the day Snivelly's going to want to be all over Scarlett like she's his girlfriend, but she's not so he's going to be all confused."

"Isn't Scarlett going to be suspicious if she's kept in a broom cupboard every night by invisible forces?" Ariella wondered aloud.

"Nope," said Sirius straight away.

"And why is that?"

"Because, Higgins," Sirius replied, "we're going to use a Memory Charm on her, aren't we? She won't remember a thing by tomorrow morning."

"Oh," said Lily, taking a sip of her juice. "You really have thought this through, haven't you?"

"As always, Evans, as always," James said with one of those smug Potter grins.

*:*:*:*

"I can't believe we're doing this."

Lily and Ariella climbed out of the portrait hole.

"I can't believe we're doing this."

They headed down the seventh-floor corridor.

"I can't believe we're doing this."

Down a narrow staircase.

"I can't believe we're doing this."

Down another staircase that would take them all the way down to the third- floor.

"I can't believe --"

"Oh shut up, Ariella," Lily cut across, as they turned into the third-floor corridor. "I can't believe we're doing this either, but at least I'm not repeating that every twenty-seconds."

"But ... oh what were we thinking?" Ariella said desperately.

Lily didn't answer. She'd been asking herself that very question ever since she woke up that morning.

"So," Lily said hesitantly. "Am -- am I going to be going first this evening, and you go tomorrow?"

"Be my guest," said Ariella.

"Urgh."

Much too soon for both Lily and Ariella's liking, they were outside the empty classroom on the second-floor. Surprisingly, all was quiet. Lily cast an apprehensive look at Ariella, who was biting her lip, and knocked on the wooden door.

The door flew open immediately, and the girls were greeted by a very vociferous Sirius, beaming.

Damn, Lily thought to herself. That bloody gorgeous smile.

"Evans! Higgins! So glad you could make it! Oh, do come in!" He said this as though he were a middle-aged woman welcoming her friends at a tea party. Sirius grabbed Lily's arm and pulled her inside the room. Lily felt as though her arm was on fire where Sirius was holding her, and she could have sworn that the cheeky little bugger was grinning to himself as he did this.

Sirius led Lily over to a seat, Ariella taking a seat next to her. Lily was surprised to discover that neither James nor Remus were in the classroom, and only Peter was in the classroom with Sirius.

"Where are James and Remus?" Ariella asked, apparently wondering the same as Lily.

"Well, I originally sent James off to deal with Scarlett, straight after tea," Sirius replied, taking a seat on the teacher's desk, "but I thought it might be a good idea if Remus went as well, to keep an eye on James and make sure he doesn't get -- er -- naughty -- with Scarlett."

"Ha ha, good thinking Sirius," said Lily, giving him a grin, "that would be just like Potter."

"Not that I can see why anybody would want to get naughty with Scarlett ..." Ariella added.

"So, they're all in that little broom cupboard right now?" Lily said.

"Yep," said Sirius, running his fingers through his hair, "Remus said they were going to Stun her. Anyway, who's going to go tonight?"

"Apparently I get the joy of dressing up as Scarlett this evening," Lily said reluctantly, frowning at Ariella.

"Speaking of dressing up," said Sirius, jumping off the table and grabbing some robes and a tie off of a desk in the far corner, "you'll need to be wearing the Slytherin robes, as I would imagine it would be very suspicious if Mirabelle Scarlett was wearing Gryffindor Robes." He threw the robes at Lily, and she caught them.

"Oh, Sirius?" Ariella asked sweetly, "why aren't any of you doing this? You know ... taking the Polyjuice Potion yourselves and tricking Snape?"

"I would have thought that would have been obvious, Higgins," Sirius answered, sitting back on the desk again. "We're not exactly experienced at being girls, let along seducing other guys."

Lily snorted.

"Would have been funny to watch you, though. Sirius Black macking on Severus Snape, ha."

Sirius grimaced as he took a small bottle of murky purple liquid out of his pocket, and walked over to give that, too, to Lily.

"That there is the Polyjuice Potion, all ready to go," he said, looking down at Lily with a curly smile. He dropped the bottle into her hand, and she caught it. "Make sure you drink it all, Evans."

Sirius Black, that devilishly sexy demon kept Lily's heart cooking like it was on a barbecue.

"I will," Lily replied, standing up and heading out of the room, robes in one hand and bottle in the other, dreamlike, as though she had suddenly been plunged into some sort of daydream.

*:*:*:*

Only minutes later, Lily Evans -- or should we say Mirabelle Scarlett -- walked into the empty classroom to find Ariella and Sirius leaning over the desk, staring at some old piece of parchment.

"This is incredible," said Ariella breathlessly. "Lily, it's the Marauders Map! I could stare at it for ever ..."

Lily strode over, and leant over the Map next to Ariella.

"Wow," said Lily, her eyes wide, "that is amazing." She looked where Ariella's finger was resting on the map, and there were three dots there, labelled 'Lily Evans', 'Ariella Higgins' and 'Sirius Black'.

"Look," said Sirius, pointing to the library area of the Marauders Map, "there's old Snivelly. At the library." He and the girls straightened up, and put his hands on Lily's shoulders and stared straight into her Mirabelle Scarlett grey eyes. "This potion wears off in an hour, so make sure that at," he looked at the clock above the blackboard, "ten past nine you take another sip of that Polyjuice, all right?"

Lily merely nodded; it seemed her throat had closed over from so much contact with Sirius. She turned on her heel and left the classroom, headed for the Library.

It was odd looking down and seeing the Slytherin tie, the Slytherin uniform, and her usual auburn hair swapped for silky black hair that reached well past her shoulders. And being so tall -- she felt slightly more graceful than she did in her Lily body, yet a lot more snootier and conceited. Perhaps some of Scarlett's personality had come through the potion.

She was at the door of the library now, and -- excellent -- there he was, greasy Snape. Time for some -- er -- fun, and time to show the Marauders, not to mention Sirius, that Lily Evans was much, much more than a straight- O, rule-abiding Head Girl.

A/N: I just noticed in Chapter One that where the love letter is it's all weird, sorry about that, I'll try to neaten it up later. I did have that part in italics but when I uploaded the chapter it got rid of the italics for some reason. And I'm going to make an effort to try and update at least once a week.

Some people have asked if this is a Sirius/Lily ship, and I'll settle with saying that's going to be the most likely romantic pairing here. ;) But remember, there's going to be some surprises ...

And I just have to put a note up here saying that I really, really, REALLY adore each of your reviews! This morning I opened my inbox to find eight new and lovely reviews, what a perfect way to start the day! Reading them makes me feel all tingly, and so happy, it's an almost indescribable feeling. And I know now that I have to finish this story, because so far each of your reviews have been GREAT! Thank you SO much! xoxo DreamingPhoenix
