A/N warning: this one's a genderbender, so if you don't like those, carry on. If you do, well here you are! I tried not to tamper with how the characters carried themselves too much.

"Alright, Evans?" The boisterous voice of Jamie Potter, Quidditch Captain, Head Girl, and known prankster carried through the Common Room, and straight to Liam Evans' ears. Liam, who was Head Boy, sighed, leaning his head back against the couch. He looked to the girls' stairs, and watched as Jamie bounded down with the rest of her cohorts in tow. Siri Black, Raemona Lupin, and Paige Pettigrew were smiling and laughing casually, finding their own space to enjoy the row that was likely to ensue.

"Find some other unfortunate soul to annoy, please, Potter." Liam placed his hand over his eyes, blocking out the loud crimson decorating every inch of the walls.

"But that would be cheating!" Liam felt the couch give a little, as Jamie obviously had plopped herself down on it.

"Cheating in what?" He sighed.

"Our relationship, of course!" She sounded aghast.

"You mean the one that exists solely in your head?"

"That's the one, love."

"You're mad." Liam managed to compress the laugh that was building in his throat. He would never willingly let on that Jamie entertained him, unless it was a day falling into the raven haired girl's favor.

"I didn't hear an objection." Jamie shifted her weight forward.

"To what?" He dropped his hand from his eyes, raising a questioning eyebrow.

"To being called love!" Her grin could have lit a city, Liam decided.

"Bugger off, Jamie."

"Anything you say, love." And she did. Jamie moved across the Common Room, over to her friends, and proceeded to tell them everything. Liam wrongly thought he'd get some piece. Until Siri dropped in that is.

"No lovers quarrel?" She pouted, resting her head of curly black hair on her hand.

"Who invited you over?"

"I'm welcome anywhere, anytime." Siri leaned forward, a glint playing in her eyes. "That's the beauty of being me, Evans."

"That's the beauty of being a slag." He corrected.

"Aren't you always the one going on about feminism?" She laughed.

"Did she send you?" He avoided the question, with a pointed glance at Jamie.

"I have my own mind." She stuck her tongue out.

"Doesn't seem that way." Liam huffed, burying his nose a little deeper in the book he'd been reading.

"Any other cheap shots you'd like to make while we're at it?" Siri crossed her arms, neatly displaying the way her shirt had maybe one-too-many buttons undone. Not that Liam was taking any sort of note to that. If anything, he noticed the way Jamie's skirt was a little too short for code, or how her messy hair was falling in strands out of her ponytail, and her shirt was a little...snug. Again, not that Liam was looking.

"You have a boy's name." Liam said calmly, trying semi-successfully to keep his mind off of the girl on the other side of the room. He was referring to the full, given name Siri had been enrolled with, which was Sirius. Her parents, apparently, had picked the name out, thinking it'd be a boy, and upon birth, were far too embarrassed to change it on the spot. So Sirius it was, and Siri was the nickname awarded to her by Jamie and the rest.

"I WAS NAMED AFTER A STAR, NOT A BLOODY PERSON! THERE'S NO SET GENDER!" Siri exclaimed loudly, slamming her fist down on the couch with every word.

"Remind Jamie about patrols would you?" Liam said, snapping his book shut, and standing. He walked to the boys' stairs, pausing just before going up them. A quick look to Jamie, and then he added, nearly to himself, "I don't want her late again."
