Sorry it's late. ugh i had writers block! And yes i know it's a lot for only the fourht chapter, but it'll be fast until maybe third or fourth year, wher i start getting into it.

R&R!

Potions was an easy task. It was like cooking, measurements and just a little too much of this could make it wrong- but it could be corrected through a bit of working- it just had weirder ingredients.

Her problem? She was partnered with a nervous Gryffindor. It sent off warning bells immediately, but their was nothing to be done about it now, she'd have to deal with it…and hope to high heavens he didn't throw in something that blew them up.

"Wait!" She stopped his hand over the potion to cure boils. "Neville, if you add that before you stir twice counter-clockwise, you'll turn it into a boil creating potion." She explained, pulling the pieces of green - rosemary strangely enough- from his hand and replacing them on the table. "Just stir it like I said- counter clockwise Neville, other direction. There ya go." She felt a bit of sweat roll down her neck. This boy…she was doomed if she left him alone at all, and she was stuck with him all year…

Unfortunately, she turned around to finish dicing up another plant, and the Gryffindor added the puss of a flobber worm about a minute earlier then directed. Yea, she found out that flobber worm puss doesn't react well to fairy dust when added together to early.

Said potion turned an angry red, before spewing at them. She shoved Neville back, earning an arm covered in red liquid that burned through her clothes! Not cool! And it hurt when it reached her arm, really, really bad.

She cringed, biting her lip rather harshly, fighting back a cry of pain as the liquid started to eat at her muscle. 'Why for fucks sake do they have us making something on our first day that reacts so violently on such a small mistake?'

Snape surged forwards, banishing the cauldron of potion and looking at her arm. "Class dismissed, leave everything as it is and get out. Longbottom, go to the Headmaster, now!" He helped her stand, working to remove the potion from her arm- and succeeding- before helping her up the stairs and heading towards the infirmary.

~In Transfiguration, 3rd year class- Gryffindor and Slytherin~

Fred frowned, rubbing at his left arm. Why was it tingling and pinching? He'd have known if he was hit with a curse, hex or charm, but he wasn't. That's when the image of Ivy Potter hit him in the face.

He blinked, she was cradling her arm to her chest and being rushed to the infirmary. How the hell did he know that? His frowned deepened, and he stared at his arm, before raising his hand. "Professor, I don't feel so good." He didn't, but he wasn't sick.

"Mr. Weasley…just go." McGonagall sighed out, she didn't feel like fighting with him, and from the unusual expression on his face, he might actually be sick for once.

Fred left quickly, resigning himself to sitting in the boys loo. Maybe he should go to someone? But if he did then who?

Parents were way out of the question, they laugh at him saying it's another prank. His head of house? Hell no, she'd dismiss him as trying to pull her leg. Flitwick? No. The Herbology Professor who's name escapes his mind as of the moment? No. (A/N really, what is her name?) Professor Sinistra? No. Professor Snape? Hell to the bloody hell no. That left two people. Madam Pomfrey and Headmaster Dumbledore. Pomfrey would think him sick or something- though maybe he was. Dumbledore it was, he decided.

…But first to the infirmary for a motion sickness cure. That pinching and stuff with his arm was making him sick.

He was quick to notice Madam Pomfrey tending to an injured Ivy at one of the beds, wrapping her arm up and tutting the entire time.

"Good thing Severus got it off! Would have eaten through the bone." She scolded.

"Sorry. But it would have gotten in Neville's face if I hadn't." The girl replied, sheepishly smiling, but wincing every now and then. At his approach though, she looked up. "Err…Fred?"

"Yes, how'd you know?" He questioned, clutching at his stomach slightly, sitting down.

"You have a different pattern to your steps then George." She explained, before brain caught up to mouth and she blushed red.

"Really?" He asked, head cocking to one side, before righting, deciding that was an unwise move at the moment.

"Y-yes. George's have more rhythm to it." She explained, nodding to Pomfrey as the woman deemed her free to go. "See you later, I gotta get to Transfiguration. Thank you Madam Pomfrey, Professor Snape. I'll try and keep a better eye on Neville next time, maybe try and teach him a bit out of class." She gave a polite nod to them, before bouncing out of the room, prompting Snape to let out a snort at her hyperactivity.

"Now, Mr. Weasley, how can I help you?" The medic asked, hands on her hips.

"Just a minor case of nausea." He replied, giving the woman a sheepish grin. The woman's temper was just short of his mothers, but even that kept him form angering the woman.

"I see, well, I can have you fixed up in one drink." She said, bringing out a sickly green potion that made the boy wonder if it was toxic, before shrugging it off and downing it, feeling his nausea increase for a half a second before it vanished.

Slipping off the bed, he gave a mock salute, before jogging of towards the Headmaster's office (it was only a hall away) and told the gargoyle he wanted to speak to Dumbledore.

On his way up he met a red faced and just barely not crying Neville, but the boy seemed more interested in the floor then him, so he continued past. He knew that look, Neville was embarrassed and guilt ridden. Best leave him on his own to sort out.

He didn't know, Dumbledore always knew who it was anyway- weather the gargoyle told him or not Fred didn't know.

"Ah…George?" He tried. Even he couldn't tell the two apart.

Fred sighed, "Fred."

"Sorry, child." The old man apologized, offering up what ever candy trip he was on, Fred declined, before speaking again. "What is it you need, Mr. Weasley."

"I…am not sure if Ivy Potter should be here for this…it does concern her." Fred wanted to squirm under the old mans gaze. Really did his eyes have to twinkle or whatever it was they did?

"Why don't you explain what you mean first, Mr. Weasley." Albus Dumbledore replied, leaning back in his chair, eyebrow raised.

"Well…it started about two weeks ago, actually. Everything was normal until I went to bed. Then I had a weird dream. It was night, and I was in a field of different flowers, a pond and it was a full moon. Their was this tree next to the pond with a lot of -pink I think- flowers on it, and under it was a girl." He paused ot take a breathe, but Dumbledore interrupted.

"That is a strange setting, but all of us have those sort of dreams at your age, Mr. Weasley." The old man said.

"Wha- no!" Fred blushed, who knew the old man was a pervert? "Nothing like that, sir! No she was crying, and when I asked her what was wrong she said it hurt. And I just sat next to her and comforted her until I woke up." He said hurriedly, "Then, at the Train Station, I saw her again. It was Ivy Potter, and she freaked when she saw me and George. But then she sent me a letter after the Sorting Feast saying the hat told her to go with the flow and trust whatever connection we had, it wouldn't say anything other than she could trust me."

"Then earlier after lunch, I was fine until my arm started to tingle and pinch. It was like I couldn't reach an itch. But I had an image of Ivy flash in my head- of her being taken to the infirmary by Snape for a hurt arm. Her left, the same one as mine. And then when I went in because it was making me nauseas she was hurt, and Madam Pomfrey was bandaging her arm saying how she was lucky Snape removed some sort of Potion before it got to her bone." He slumped back, utterly confused.

Dumbledore leaned forward, lacing his hands together and settled so his mouth was hidden by them. "Fred, was the first night and actual full moon?" He questioned, loosing all sense of formality.

"Now that I think about it…yea, it was. I remember because George and I were teasing Ginny that a werewolf was going to get her in her sleep." He answered, eyeing the Headmaster with a 'Why-Does-This-Matter' expression.

Albus took a spare piece of parchment and wrote on it, before turning to Fawkes. "Fawkes, take this to Minerva, that's the class Miss Potter has at the moment." He said. The Bird of Fire trilled, taking the rolled up parchment in his beak and vanishing in a swirl of flames.

"…Sir?"

"I wish you'd brought this to my attention much sooner. This is actually very serious. But I must implore you to wait until Miss Potter is present, it would be easier to handle this all at once." The blue eyed man said tiredly, leaning back once more.

Fred decided to just fidget in his seat while they waited, and it wasn't long before Dumbledore gave the permission for her to enter, and she was opening the door.

"Headmaster." She offered, shifting on her feet. Geez, what did she do? This wasn't about the incident in Potion's was it? That wasn't really her fault…

"Miss Potter, why don't you join us?" He replied politely, gesturing to the unused chair next to the red head.

"Alright." She said slowly, complying with him, shifting slightly so she could comfortably lean back in her chair. She looked from Fred to Dumbledore before speaking, "This is about what happened half a month ago…isn't it?"

Albus nodded. "Very perceptive, Miss Potter. Correct, it is."

She snorted. "I've interacted with Fred maybe three to four times, it's not like either of us could be in trouble in school for the same thing. It's not being perceptive, it's knowing the only common thing we have at the moment." She let her green eyes flicker to the crimson bird that had taken to perching on the back of her seat. "So, if you've got an explanation spill it. I have a meeting with my Head of House tonight I'd rather not miss." She would normally be polite, but she wanted to know why this stranger was able to get into her only safe haven.

"Direct, much like your grandfather was, he was a good man." Dumbledore returned to topic. "Have either of you felt…different when the Full Moon is out?"

She tilted her head, "I…yes, I have. Frequently." He dumped her on the Dursley's door step, if that was so, he had no business with her life at home anymore. She couldn't trust him to do anything about it, especially when her aunt told her Severus Snape could help.

He narrowed his eyes only slightly at the hesitation, before turning to the Weasley in the room. "And you, Mr. Weasley."

He nodded, fidgeting with his robes again. "Yes. Stronger, sometimes I can't sleep, I feel to full of energy."

Dumbledore sighed, "I guess I'll have to use a bit of history." He leaned forward again, shuffling papers as he spoke. "In the olden days, when magic was still very wild and untamed, their were Wars just like their used to be. We- the few who have studied these Wars- call them the Sun and Moon Wars. The Moon is actually a symbol of strong magic, and their was a clan that called themselves Moon Mages." He began, "They were normally witches- and the occasional wizard- who could call on the Moons magic at will, but the problem was that in order to perform it, they could not be doing anything else, it called on focus. But it was the very Moon that lent them it's power, so it created people who were either a few years older or the same age as that Mage. They were the Mages other half."

"They were called Warriors. They would protect the Mages whilst they called on the Moons magic, often they were lovers, but their was always the possibility of siblings or every now and again parent and child." He flitted his eyes over the two before speaking again. "But the opposing Sun Clan wanted to wipe out the Moon Clan because of an old grudge no one could remember, and it was the same way, only with the Sun instead of the Moon. However, a girl was born of both clans from two lovers that had been secretly meeting. Her other half was split in two- one from the Sun Clan the other form the Moon Clan."

"Wouldn't that mean she was caught in between?" Fred asked.

"Yes, it did. She couldn't fight either clan, and became shunned. But both of her other halves had been fighting each other when she stumbled upon their fight after what we think was a bear or lion attack. Upon seeing her at the same time, they realized what had happened and set aside their differences to save her. She had been unable to use the powers of either celestial beings because her other halves were fighting each other, but when the three came together- and yes, the three were lovers- she could call on both. She was taught the ways of both clans from both men, and learned that neither was really that different from the other, and in the end through much more violence brought the clans together."

"We traced the lines down through families, but lost it about a century before the founders. Ivy, do you have any unusual markings aside form your scar? Say a scorpion or a perhaps a small bird?" The Headmaster asked, looking at her curiously.

"W-well…" She lifted her hair off her neck, revealing what looked like a small scorpion at the base, before showing her right hand, palm up. Resting on her inner wrist was an very small bird. Both were a dull pink red, almost like scars.

"Ah, that explains things much easier. The Scorpion was the symbol of the Moon Clan, whilst the bird is a Phoenix the symbol of the Sun Clan. And you, Fred?" He revealed a scorpion on left shoulder- a place he'd always kept hidden. "And what of your brother, does he bare a marking?"

Fred nodded shakily. "Right shoulder, it's a phoenix."

"Whoa, back up. Are you telling me you think-"

"Yes, I'm telling you I think you're the reincarnations of those three, it would not surprise me if George started feeling the same connection you do, Fred, and very soon." Albus sighed. "This does mean the three of you can't be separated for long periods of time, meaning you, Miss Potter, shouldn't be returning to Private Drive."

That's when she snapped. "Oh, NOW you want me to leave? NOW? Why not keep me from there before now? You dumped me on their doorstep!"

"Miss Potter, it's where you are safest. Blood Wards that your mother placed will keep you safe from any Death Eaters or magic kind that wish you harm." He explained, frowning at her outburst.

"MAGIC KIND? That's all you stopped to think about?" SHe whipped around, raising her shirt up and exposing her back, "What about the non-magic kind, Albus Dumbledore? You didn't stop and think about them did you? Vernon HATES me. I can't tell you how many times I've passed out in the bushes trying to weed the thing because I get to hot, then get beat for passing out. I can tell you it took one beating for me to learn to never get better grades then Dudley, EVER. Do you know where my bedroom was until I got my letter? A goddamned cupboard. And don't you dare spout off some shit about it being for my own good!" She spun around again, eyes a violent glowing green, and several of the objects in the room where rattling. "And now you tell me that you don't want me to go back, that I'm somehow supposed to be all buddy-buddy with two people I don't know, two people that will probably wind up hating me later for fucking up their lives? It's a little late, but whatever go ahead, you've already screwed me up."

She slammed herself back in her chair, ignoring the sound of glass that was a window behind them shattering, and looking at the old man expectantly. "Waiting, and I'm certainly not getting any younger here."

Dumbledore leaned back, eyes closing. He should have listened to Minerva all those years ago. "Forgive me… I didn't know…I really didn't."

She shrugged. "Just make sure Vernon can't hurt Aunt Petunia, and that Dudley gets some help and I won't give a damn. I'm not some little girl who thinks this is normal. I've had Aunt Petunia to explain things to me since I could understand English, but on the topic, talk to my Head of House. I'm pretty sure the letter form my Aunt I gave him is about some big escape plan. You can deal with it and I'll talk to him on a later date." She said tiredly. Great, emotional drowning here we come!

He nodded slowly, "I'll be removing you form your dormitories in to a three bedroom, three bathroom, personal dorm. It's kept ready incase we have students with personal cases such as this, and normally a married couple that has been arranged can only be up to three people in one. The rooms are separate, no worries. You will still be apart of your Houses, but this is so the connection will fully form, if it doesn't, it could be hazardous to health." He decided. "Fred, I'd like you to inform George of everything, and be ready to move out by tomorrow night. Ivy just be ready then. Speak of this to no one, I'll tell your family tomorrow."

Ivy stood up, "Sure." She turned on her heel and stalked off.

Fred followed her, brain a scrambled mess as he tried to absorb all that had been said. So he and his brother had two choices. Fall in love with the Girl-Who-Lived, or see her as a sister.

Well, this proved George right. He did say he thought they were going to have an interesting year.
