Harry Potter and Big Sister

Chapter 3: Into the Dark night

Harry suddenly heard a loud banging sound continuously like someone just hit and dropped an entire kitchenware from the cupboard down from below him which woke him up from his slumber. He moaned, hands fumbling around trying to find his wand and glasses that he was sure to leave it near his bed, only to suddenly stumbled upon and get a hold on something soft and squishy.

Then, without warning, a dark-skinned hand shot forward in front of him, putting his glasses on, the strange part is, that wasn't his own hand, but someone, with his eyes still blurring from sudden wake up and still not used to the darkness around him, he couldn't see who responsible for his glasses, or who was making a noise below at all, though to be fair, in the latter case, no one would've see it unless they have that Mad-Eye Moody's magical eye.

"Kid… wakes up now…" His Big Sister hissed quietly into his right ear, anger evident in her voice. "And if you please, get your hand away from my chest before I electrocute you!"

The boy's eyes widen and look to his right, and now see clearly that his hand, which grabbed on something soft earlier, was in fact his Big Sis's chest! He nearly shouting apology when her gloved hand shot forward and clamped his mouth shut before she whisper in murderous tone. "Save apology for the later, hand off me, NOW! And ready your wand, there's a breach in the lower floor, someone not Dursleys are inside this house already!"

Harry quickly complies with her demand and pulled his hand away from her chest, not that there's much for him to feel there, he added mentally, but shook it aside in seconds, there's no time for such pervert thought now, Big Sis's last sentence hit him with a shrill in his heart, someone, who's not Dursley just invaded into this home! He jumped out of the bed, grabbed his wand and rushed to the side of the door leading into his room, prepare to curse anyone who try to enter.

Meanwhile, his Big Sister already there at another side, brandished her steel-grey walking stick that look more like a long staff with wings on one end out, her ear stick to the wall trying to listen to the mysterious intruder below, her frown deepen by the second before she whispers. "There're more of them than I expected, damn… at least five… we need to hold this choke point, but if they can use apparition as described in your book, then it's pretty much useless…"

Her word was cut short by the clicking sound from the doorknob, signified that the lock has been undone, she quickly held her staff up, ready to smack the first person who move past this door, however, the footsteps sound died out, not at the front of this door, but below, which mean that the intruder use 'Alohomora' spell to undone the lock from distance, maybe not wanted to risk him or herself getting this close to Harry's room which has them dug in.

Minute has passed, no one on both side move into other side's sight, or rather, into other side's smashing range, the intruders remained downstairs, while both Harry and Big Sister holding up in his room on the second floor. Harry's heart skipped beat due to stress, questions keep popping up in his mind, who are those people? What did they want? And why don't they just apparate into his room and negate their choke point advantage already?

Then suddenly, a low growled boom through those many whispering below, directing at both Harry and his Big Sister, specifically his Big Sister, if those numbers of threats they made has anything to say. "I know you're waiting behind that door holding Harry Potter hostage with whatever mind control tricks you have! But we have numerical advantage here, you can't defeat us all! The ward here prevents anyone from apparate in or out so you're trapped! Surrender now or face the consequence!"

But, the voice was so familiar to Harry that he couldn't help but reply back with surprise and uncertainty, even if it earned him a glare from the older girl on the opposite side for breaking their ambush, not that it already failed if that person is who he think he is. "Professor Moody!?"

The whispers stopped suddenly, then the same growled echo through the door again. "I don't know about that 'professor' thing boy, never been one, now get out of there!"

Now Harry was more or less convinced that the other side, one floor below, really his 'supposed' former Professor in Defense Against the Dark Art, but still, memories of the fake Moody still haunt him, thus he whispered to his Big Sis. "Sis, I'm not sure if he's the real Moody or not, but we can't hold out here for long as well, so…" he then stopped because he suddenly realized that it is the most stupid idea he ever came up with, if the ward Dumbledore put up here prevent anyone from apparating, then why should they abandon this choke point? It offered the biggest advantage for them since the opposition can only come at them one by one, isn't it?

However, his Big Sis suddenly smirking, clearly some idea must have formed up in her mind, before continues what he left out aloud for those below to hear. "So we're going out and hope that these guys are not the lackeys Voldermort send here to kill you? Yeah, right…"

The moment word 'Voldermort' left her mouth, at least three gasping sound was heard even at this distance thanks to the silence that befall a moment before she stated that out. Harry sighed when he heard the gasping, if these people afraid of Voldermort and not fly in rage and curse them back when a stranger spoke his name out loud, then yes, they're quite on his side, almost 90% of his mind says so, that is, another 10% still paranoid if they might not be the case.

Nodded once to his Big Sis, she whispered. "I'll go out first, you follow and prepare to jinx them if they try anything funny, got it?"

"Wait, they're still thought that you mind controlling me!" Harry quickly disagreed with her, and volunteered himself. "They'll open fire if you showed up first, but they won't do that on me Big Sis!"

But Big Sis just gave him a small smile and replies. "Thanks for the concern, but, as the elder in my homeland says 'do not judge the book by its cover', even you know it that I'm more than meet the eye right?" She winked at him a bit mischievously, and before he know it, the door slammed opened out to the hallway and then, Big Sis wave her free hand up front while shouting "Stupefy!" shooting four so-very-familiar red bolts of light out of her palm and quickly close the door back before the inevitable impact on the wall at the opposite side of hallway.

Harry nearly jumped in rage with that action, he practically shouted at his Big Sis who seems to suddenly close her eyes with her palm touching her temple. "What are you doing? Firing spells into blank wall to distract them? Dursley will have my head for this if we can't repair it in time!" Even it was a stunner spell, but it still somehow able to damage physical objects when struck one, even though it doesn't have the power like, says, Reducto curse, it still leave a burnt marks at least anyway, so it's not surprise for this outburst.

However, his tirade was cut short by series of shouting, yelling, filled with surprise and panic from the lower floor reached his ears, along with sounds of furniture, housewares and kitchenware getting trashed, smashed, during the chaos caused by people below them who yelled out in surprise of something that was attacking them.

"What is that? Ugh!"

"Dodge it! Dodge it!"

"Why that thing keep following me… watch out Arthur! Ow!"

The sound of something heavy, like human body dropped down on the cold floor one by one, and then before Harry could asks his Big Sis what kind of Stupefy spell she just casted, she kicked the door open again, but this time, she send him a hand signal, then charged out of the room, staff in hand, prompted him to follow her.

Once he jumped down the dark staircase and finally landed on the ground, the first thing he noticed is that one witch with short pink hair in robe slumped down near the staircase, immobilized by the Stunner charm Big Sis casted earlier, next to him is the kitchen where the noise of fighting could be heard from within, he rushed to the door to get a peek into the room only to found one dark-skinned wizard groveled unconscious next to the doorframe, his face unrecognizable by Harry, because he never met him before, same as the witch that was stunned at the staircase.

The sound of metal hitting flesh can be heard along with cries of pain from Moody who was send crash-landed on the floor next to him, nose bleeding, forcing Harry to dropped down to the floor to avoid attention before looking at the direction where Moody came from, and finally found his Big Sis, but she's not alone…

Red haired middle-aged wizard is backpedalling away from the white and purple figure that tried to rush in, shooting curses and hex without aiming to slow the thing down without much success when the figure in question, Big Sister, simply used her staff and sheer agility to block and deflect all incoming projectiles in her path while pressing forward. But the wizard's luck still on his side, or he was experience enough to not get cornered, and another wizard, this one has grey hair shooting curses from behind, forcing Big Sis to stopped pursuit red-hair one and spun her staff to block the sneak attack without even looking at the assailant.

Harry's jaw dropped, awed at his Big Sister's display of experience and before snapped out of it when she deflect another reducto curse back at the red hair man, missed by just an inch above his head, and shot her palm at the grey haired one, electric crackled between her fingers trying to grab his body's part and fry him, he knew both of them! And that he needs to stop them from harming each other, so he shouts loudly. "Sis, stop!"

Big Sister gracefully dodged the last batch of curses from both wizards, let them blew up a portion of doorframe behind into pieces of wood, and stopped her pursuit to harm her foe, but the staff in her hand still pointed at the red haired wizard, another hand crackle lightning, her purple eyes glancing and shifting around looking out for possible sneak attack, then she asks him. "What? Kid? Are you sure they're not Voldermort's lackey disguised as someone you know?" the redhead flinched at the mention of the Dark Lord's name, while the grey haired one still trained his wand at the girl, eyeing her cautiously.

"Because if they're, they won't stop attacking likes this, Sis." Harry reasoned, pocketed his wand to show both sides that they should stop. "And considered how you cut their number by half in a matter of seconds, they would've used the Unforgivable by now, not some normal spells like this."

"Point taken… but I still demand you to prove that they're not like what I'm suspecting." Big Sister replied while slowly back away from both wizards to stand by his side, something that he was grateful of. Meanwhile, both wizards still pointed the glowing tips of their wands at his Big Sis, but didn't attack, seem they're confused as well.

Harry now looking at his former Defense Against the Dark Art teacher, the grey haired one, before he asked him something that sounds nonsense, yet perfect for proving that his former professor really is former professor, not imposter. "What Boggart turned into when it saw me?"

The grey haired man who, from the dimly lit light on his wand, has many wrinkles and bony face as if he hadn't have a good meal for year eyed him cautiously before replies "It turned into Dementor. And now you should answer me this, what your Patronus looks like?"

"A male deer." Harry spoke without hesitation, before telling his Big Sis who still on guard. "It's them, I'm sure now, Sis."

She lowered her staff, lightning vanished from her palm, before pressing a switch next to them and light up the room so everyone can see each other clearly, that, and a mess of a kitchen that looks like a tornado just rampaged in there.

Across the table that somehow miraculously survived the onslaught unscratched is Arthur Weasley, the redhead wizard, father of seven Weasley which all of them are his friends, he seems to sigh in relieves after he saw that Harry still safe and sound.

Next to him, is his former professor, Remus Lupin, who let out a small smile to him, before turning attention toward others who was unconscious on the floor thanks to Big Sis's action, then move to help them with Big Sister keeping her eyes trained on him the whole time while slinging her staff onto her back to at least showed them that she now meant no harm.

Once Lupin got the pink haired woman up, although still dazing and unable to see clearly, he helped moved her toward the kitchen, while Arthur move passed by Big Sis and casting spell on the fallen black man and Moody, both groaned before slowly getting up, while the ex-Auror spoke first, hand holding his still-bleeding nose.

"What the bloody hell just hit me?"

Arthur, who probably saw everything since he was the only one san Lupin who still conscious after the fight, explained. "You get smashed in the nose by her staff…" he pointed at the purple haired girl. "…and send you flying a good twenty feet away. But put that aside, how do you feel? Is there anything broken?"

"Nothing except my nose," Moody grumbled, waved his wand to fix his nose, then turned toward the one who cause his injury "So, who the hell are you?"

"She's someone who I met long time ago." Harry who stood by the girl's side explained. "She came back to visit me, but then you broke into the house, so we thought you were all imposters and tried to defend ourselves."

"It didn't help that you, Moody, suddenly make a threat against them when they're upstairs too…" the witch who had pink hair quipped at the old man, hand rubbing her head which clearly has a purple mark from falling down hitting staircase on it, clearly not amused by the fact that she could've avoid it if not because of this. "… And so they fired spells downstairs and knock me out! Plus Kingsley too!" She motioned toward the black skinned man who lean against the wall, slowly breathing and not join the conversation.

Arthur sighed. "And Arabella already told us about her, and what she look like."

"And I told Dumbledore that we cannot just trust someone who popped out of nowhere to rescued Harry!" Moody shot back, glaring at Big Sis who stood still. "Especially when we are up against You-Know-Who, everything is suspicious!"

Big Sis seems to have enough of Moody's ranting, so she asked him calmly "So what? This Voldermort aim to kill Harry isn't he? If I was his lackey then I'll have more than hundreds of opportunity to off him during these past two days, why should I wait till you guys show up?"

Moody scowled, but cannot deny the girl's logic, so the previous silent black man, Kingsley it seems, stepped up next to the Boy-Who-Lived before turning to the group. "She has a point, Alastor" he reasoned with the ex-Auror. "The important thing right now is to get Harry out of here, and as Arabella Figg had voiced her thought to us, she's trustworthy enough, so the girl can come too." He motioned toward Big Sis.

Arthur coughed once, before speaking to Harry. "Well, Harry, best to gather your things, we're leaving now, Nymphadora, could you help him out."

"Don't call me Nymphadora, called me Tonk!" the witch snapped back as she begun to approach Harry and Big Sis. "Watcha, Harry, so where's your room?"

"This way…" Harry gesture toward, and then move to the stairs, while his Big Sis seem to be contented with a glaring contest against Moody who seems still not trust her, and to be fair, he also still skeptical about the new face in this house too, but if Mr. Weasley and Professor Lupin trusted them, then he could trust them too.

"So, Harry…" the witch started her conversation when they reached the room. "…where did you find that girl anyway? She look pretty I must admit, but why calling her your Big Sister? I never recalled that the Potters has daughter as well, and she's about your age for crying out loud!"

"She's not blood related, but we knew each other since I'm eight…" Harry replied with a shrug as he passed Tonk his books, which she proceed to dumped them into his trunk in turn. "…She told me that she was fifteen back then, and she seems to suffer from rare condition that slowed down her growth, so I think it's normal."

"Weird…" Tonk muttered, before tossing another box into the trunk, looking around the room then she asks with air of professionalism. "Well, anything else? I don't mind if you take some of those toys with us, my dad always brought it for me when I was a kid, and then getting dumped in the storage when I grew up, messy like this every time I open that room to look for something."

"Er, no… that's all we need here." Harry answered, picking up Hedwig's cage, walk toward the trunk and lay it in last. "Well, that's all we need." He told her, which prompted Tonk to flick her wand and levitated the object to follow behind them.

Together, the two of them returned downstairs where other wizards and Big Sis are waiting, Moody still locked in a standoff, ready to hex Big Sis the moment she do something threatening, while Big Sis seems to lost interest in the old Auror and start conversation with Mr. Weasley, asking him about wizarding world if the dialogue he heard was anything to go by, all while still rolling her eyes to look at the surrounding, ready for anything, pretty much like what old soldier would do.

"Everything is alright? Harry?" Mr. Weasley looked up and asks when he heard Harry and Tonk's footsteps, along with his Big Sis who turned her head toward him as well.

"Yes, Mr. Weasley." Harry replies, while looking at his magic broom which somehow found its way into Professor Lupin's hand near the kitchen, then again, he kept it in the cupboard below the stairs so it's logical that they would've found it when they're roaming around earlier, he eyed his belonging intently, feeling something is about to happen and asks. "But, where are we going? The Burrow?"

Moody opened his mouth to replies, but his Big Sis beat him to a punch. "Hey? Are you going to leave this mess unattended?" She pointed at the mess of a kitchen.

"Then you better stay here and clean it then." Moody retorted, clearly wished that she'll do just that so he could get rid of someone suspicious from the group, something that other seems to disagree and decided to put out a wand and waved around, repairing the damage, putting kitchenware back to shelves.

"C'mon Moody, Don't spoils their long await reunion." Tonk joked a bit, looking at the girl who was smiling a bit in amusement at the pink haired witch. "They're apart for seven years, If she's really working for You-Know-Who, Harry wouldn't made it past his eighth birthday like this, she would've offed him long before Hogwarts' letter even reached him." The girl nodded as to confirm Tonk's claims at the last sentence.

The ex-Auror grumbled, but did not response to Tonk, instead, he turned toward Harry and continue where they left off. "We cannot go to the Burrow, it's not safe there! Dumbledore got a better place lined up for us! Now that all you need to know, let's get moving!"

"Dumbledore?" Harry blinked as Mr. Weasley returned his broomstick, which his Sister eyeing with interest.

"Yes, but we have to get moving now, explanation comes later." Mr. Weasley answers and repeated what Moody just ordered, then move out of the house, with everyone forming a protective circle around Harry and Big Sister when they reached front lawn of Dursley's house.

Harry felt his temper boiling at their denial of him from information, after everything that happened, attacked by Dementors, forced into trial, and they still thought he should been left out of the loop instead of letting him know at least where they're going! Glancing back at his Big Sis who still watching all wizards and a witch with interest did calm him a bit down even with her own secret, because in her case, it's justified. And that she's as in the dark about what the adults were doing as he is as well, so at least he could find some companionship in her.

One by one, each of them picked up their broom which was hidden behind the dried foliage, prompting Harry to put himself up on his Firebolt, then he realized that his Big Sister doesn't have one to travel with them! So he looked at the girl who was staring at his broom with even interest now that it's hovering a foot in mid-air like this, and then asks other. "Wait, how are we going to take her with us?"

"Let her walk," Moody replies, clearly mistrust the girl "So we have enough time to plan for her."

"Alastor…" Arthur sighed at ex-Auror, and then turned toward Tonk, who proceed to replies despite Mr. Weasley haven't says anything yet. "Well, if my broom is not carrying this…" she pointed at her short broomstick, just enough for Harry's trunk to fit on. "… I would've takes her with me already… and I doubt any of you guys will have enough room, consider your size..."

Harry then looked at his own broom and voices his opinion "Well, mine has enough room for another, but it might a bit cramped, well Sis?" He then looked at the purple haired girl in question, whose purple eyes stared at the broomstick, deep in thought, before she snapped out of it when he repeats his question. "Sis, can you ride on my broom along with me then?"

She slowly reached for his Firebolt, her hand rubbing along the broom as if she was feeling for something, then mutters "Quite enchantments you've got in this thing huh?" then she felt many eyes starring on her, when she look around she found that everyone was awaiting her opinions, especially Moody who's ready to ditch her here, so she chuckled, then tell Harry "very well, I think I could hitch your rides for a while." She then sit on the Firebolt behind Harry, one hand stretched out to grab his shoulder "Well, let's go should we?"

And then all of them kicked off and flew up into the sky, heading off toward the destination Harry and his Big Sis did not know.

---

One Hour later…

The darkness of the night sky enveloped a group of witches and wizards that flew through, Tonk was leading them at front while Mr. Weasley was a flying bit below them, behind Tonk was Moody and Lupin, then Kingsley at the backmost, with Harry and his Big Sis protected at the center of formation. He was cold and wished that this flight could end right here and now thanks to flying through the cloud once as Moody's command, which made him soaked with water vapor, wind blowing on his eyes which barely see anything aside from small bright dots which denoted the house or lampposts, or any form of town, city, villages which he couldn't make out details below, denied him any knowledge about where they are going.

Looking backward to his Big Sis, she still sitting on his broom, turning sideway as not to face him and enjoy the scene below them, the artificial light of the normal human's residences, and the night sky devoid of moon, letting the stars shines brightly, or those many clouds that formed into various shapes that sometime Moody ordered them to flied straight right through them to shake off the non-existence pursuers, which keep him, and everyone else wet and shivers, except only his Big Sister who still remain dry in her warm winter-like clothing…

Speaking of which, Harry cringed at the barks of order from Moody to dive into another cloud again, but have to follow nonetheless, however, this time he glance his eyes at his Big Sister, who seems not concern about them going to pass mass of vapor that much, paying attention to what she's doing, but then she noticed him staring at her, so she smile, waved her hand once, and suddenly the sounds of wind rushing by his ears slowly diminishing until he could clearly hear her voice despite she spoke in normal volume. "Sorry, I didn't think that you'll not know this technique, and I'm kind of getting carried away by sightseeing…"

She pointed her hand to the front, which, when he looked there, he found that they were surrounded by a small cyclone, with them at its epicenter, a mere moment before they entered the cloud following his 'Guardians' thus he prepare himself for another wet sensation and being soaked with water again…

The coldness didn't come, in fact, the wind summoned by his Big Sis that whirled around them, although strong enough to ward off cloud of vapors from passing through, did not impaired his vision that much, apart from the dark natural cloud, he still able to see where the rest of the formation were going, and able to follow them without accident.

Harry excitedly exclaimed. "Wicked!" then he asks his Big Sister while still keeping track of their path. "Can you teach this spell to me?" Of course, if he knows this spell, he'll be sure to have massive advantage the next time he has to play Quidditch in the rain.

But what his Big Sister answer surprised him even more, because she chuckled "What spell? This one has no incantation, no long boring chanting like that Stupefy I mimicked earlier, you just channel power with your thought, empowered with nature, and it happened."

"What, you're saying that you never chant spell at all?" He asked, clearly half of her explanation didn't reached his thought at all.

"If you mean me in the past then yes, I once need to chant the spells to use them, but now? I'll only chant or spoke incantations for the heck of it, kid." She elaborates, then proceed to crush his hope by the next sentence. "As for teaching you, not now, you're not ready for it…"

Harry fumed with irritation, something that Big Sis caught on and confront him with the her words "…there's an old saying in my land, it goes as thus 'Do not accept apprentice nor parting them your knowledge so easily', do you know what that really meant, Harry?"

Harry steered his broom to the right to follow other, then shook his head, so his Big Sis explain. "They meant that people has different thought, different traits, what will happen if you taught the one with evil intent how to use a gun? What will happen if you taught, says, the Unforgivable to the kid who knows not of moral code? What's going to happen, is we'll have a criminal in the making…"

Her words brought forth the memories of Tom Marvolo Riddle, or Lord Voldermort as he is called now, the fact that he graduated from Hogwarts was all it take for Harry to understand what she just implied, and why she cannot taught any of her arts so easily. Further drove the point home by her conclusion. "What I knew, was some of the most dangerous arts of magecraft in existence, Harry, even someone with good intention but without skills to handle it will wrought forth havoc as good as the one who has skills to use them, but with evil intent in mind."

Harry was silent, his mood cool down a lot after she reminded him of the 'Emperor Lightning' that fried Dementors, and clearly see her points now, he didn't speaks until Tonk broke the silence between the two, shouting at Mad-Eye to stop this wild goose chase and go to base, and then he found them descending down toward the town below.

And at last, they touched the ground once more, which was very lucky that they're in the park which devoid of every life form, especially human, because it was 1 in the morning at the time, as Harry dismounted the broom along with Big Sis, he slowly looking around, he summarized that they may be in a part of London from the size and look of buildings surrounding them, the cyclone his Big Sis summoned vanished seconds before they touched down, so no other wizards and witches could see anything wrong about them…

Well, exception maybe his Big Sister, who's not soaked in rain which caught Tonk's attention immediately.

"Wow, you're not wet at all? How can you do that?" She asked, moving around his Big Sis to get a good look at her from all angles. However Moody saved her from answering that question by barking order again…

"Go now, no time for small talk!"

The group quickly approaching the townhouse on the other side of the park silently, as they got closer, Harry then noticed that the group seems to move toward one particular house, specifically the empty space between #11 and #13, and then they suddenly halt when they're right in the middle between the two houses. Confused, Harry looking around expecting someone to answer him, while his Big Sis knelt down stretching her hand to touch the ground, eyes closed with a small frown…

And then she spoke up "There's an unnatural magic enchantment here, if I were to guess, it hid the No.12 house from us." She glanced at the empty space, eyeing it suspiciously "Well, nice way of hiding things there."

Moody quickly questions her, eyes narrowed dangerously. "How the hell do you know?"

She replied cryptically with a small smile, much to the old man's annoyance. "I sensed it of course."

Seeing that Moody ready to start another fight, Arthur stepped in between the two and warned the ex-Auror about their duty, which made the old man grunted in displeasure, but did not say anything while putting out a small parchment and handed it to Harry who stood next to Big Sis. Taking the parchment, Harry and Big Sis shared the view of the texts written on it in a loopy style.

"The Order of the Phoenix's Headquarter can be found at No.12 Grimmauld Place."

Harry recognized the writing style on it immediately, this was obliviously from Dumbledore! But he still can't figure out how this thing will do him any good, but once he looked up, he suddenly found the missing 'No. 12' house standing in the empty space that before, was a space between No.11 and No.13, like the No. 12 just appeared out of nowhere!

Mr. Weasley grinned at Harry who was staring at the house slack-jawed. "Well, what are we waiting for, let go in, everyone is waiting for us."

The group approached the door of the newly appeared house, then opened it and get inside.

Harry looking past his escorts and found himself in the narrow hallway illuminated by a single chandelier on the ceiling, projecting a gloomy atmosphere all over the place that already was as it is crawled with peeling wallpapers, a half-chewed carpet that clearly has no one to take care for in decades, and a ragged curtain hanging on the wall, all in all, certainly not the most cleaned place you can find.

"Waaah!" a loud scream can be heard from Tonk, who apparently tried to move across the hallway but accidentally tripped over on the umbrella stand that looks like it was made by a Troll's leg, the pink haired witch was seen sprawling on the ground, groan in pain while trying to stand up, but at that instant, the curtain which Harry thought covering a window suddenly opened, revealing a large portrait of an old lady who take one look at the group of people and went into frenzy screaming on top of her lung, if she has one at all that is…

"FILTH! BLOOD TRAITOR! MUDBLOOD! YOU DON'T BELONG HERE! GET OUT AT ONCE!" More and more racial slurs come forth from the portraits with increasing rage and fanatical tone that mad Harry started to twitch his eyebrows in displeasures.

Glancing at his Big Sis, she was lifting her hand up to her chin and studying the screaming picture intensely. And he could make out the word she is muttering a little. "Interesting, imparts one's memories into a picture huh? Your wizardkind surely has many ways to defies laws of nature I see…"

Then before she could continue further, a gentleman in brown wizard robe with black stingy hair and black beard on his face descending down the stairs while yelling at the picture "That's enough you old hag!" However, that only made the picture changed her target at the man instead, which he promptly shut her up by pulling back the curtain to cover her portraits, which is quite a difficult tasks considered that somehow the curtain seems to resist the pulling, but after a couple of seconds, it closed shut and the screech died down.

Harry then found himself staring at his father's best friend, Sirius Black.

"Well, Harry" Sirius sighed, then look at the group before his eyes stopped at his godson. "I see that you've met my mother."

"What? Your mother?" Harry stare at the curtain, clearly disbelieved that this violent, racist, and fanatical woman was Sirius's mother.

"Yes," Sirius replied, and at the same time, the door at the end of the hallway opened with a sound of rushing footsteps coming toward them, and Harry then treated with the sight of Mrs. Weasley, one of the most kindhearted mother he ever known of, however he suddenly feels worry when he saw that she was a bit paler and thinner than the last time he saw her, which is just a few months ago!

"Oh, I'm happy to see you here at last Harry." Mrs. Weasley greeted him with a small whisper and a bone-crushing hug, then lowered him down and turn toward the purple haired girl of the group "I heard that you're the one that Harry called 'Big Sis' all these years, you have my thanks for helping the poor boy out before."

"You reminded me, Molly…" Sirius then looked at the girl and extended his hand to shake, which she also complied "…I thank you for looking after him, I means that seven years ago too, young lady."

Big Sis nodded and smiles at both of them a bit, and then Mrs. Weasley turned to address the group of adults. "Dumbledore just arrived, the meeting will be held soon, you all should get going." All the adults seems to excited at that words and started to make a beeline toward the door Mrs. Weasley came out earlier. But once she saw that both Harry and Big Sis are all interested and tried to follow, she shook her head, moved to block the way to the door and says. "Sorry, dear, but you two cannot come with us, only the member of Order of Phoenix can come in, now go upstairs" She pointed at the staircase which Sirius came out.

"But, Mrs. Weasley, what's Order…"

Harry didn't get to finished his question however, as Mrs. Weasley cut him off mid-sentence. "Ron and Hermione will explain everything to you two, go to the second floor, first door to the right, I must go now." Without any more word, Mrs. Weasley quickly moved past the door and shut it closed, leaving the two alone in the hallway.

Slowly approaching the door, Harry stretched his hand out, trying to push it as if to test if he can force his way in, but all of the sudden, Big Sis quickly grabbed said hand and pull him away from the door mere inches before he could touch it.

She then scolds him, stern angry look burned in her bright purple eyes. "The hells are you thinking? Trying to push a door that has an enchantment etched onto it? If you keep up this habit, all that Voldermort needed to kill you is just put up a trap door saying 'Weapon to defeat Lord Voldermort behind this door, do not open' in the middle of nowhere for you to find!"

Harry's anger at the interruption died down due to the more pressing matter, "How can Sis know that…" He asks.

"Know that the door was cursed?" She completed the sentence for him, looking directly in his clearly innocent-green eyes and sighed. "Seriously, what the hell they are teaching here?" Then she walk up the dirty staircase, motioned him to follow her. "Let's wait where they wanted us to be then."

Harry was quite fed up with his Big Sis playing this 'obedient girl' image with those adults a lot, but then he realized when he looked at her inspecting the surrounding doors as if to see whether they're cursed or not, that in fact, she didn't have much choices, she's a stranger in a strange land differ from where she came from, and acting rebellious is asking for trouble, not mentioned that they were in some sort of secret meeting place of this 'Order of Phoenix' so it wouldn't be surprise if they'll just oblivate her if not because of his presence and assurance that she is on their side, or at least, on his side.

Cooling his head down, he approach the girl, turned right and open the doorknob that looks like a snake's head as Mrs. Weasley instructed, and found himself inside a tall room with two beds inside, sound of birds, and the bushy haired girl of his age who jumped on him, followed by another redhead who seems entranced at the sight of him, or his Big Sis, he didn't know when Hermione started speaking rapidly. "Harry! You've come here finally! We didn't hear you at all! Seems you must angry with us right? I'm sorry, but Dumbledore made us swear not to reveal anything! We have a lot to tell you! And I'm sorry about the Dementors! I'm sure they can't expel you, you've the rights to defend yourself in such situation!"

Harry heard a chuckling from behind him, and figured out that his Big Sis might found this scene amusing. And sure enough, when she spoke up, chuckling all the way, it is as he thought. "Heh, you've made quite a friends, kid, I must admit."

That made Hermione immediately released Harry, face redden a bit at the embarrassing display to another stranger she once heard from her friend but never meet face to face, fear that she might just ruined the first impression, she apologize to Big Sis, Ignoring a sound of flapping wings, and Hedwig the snow owl landing on Harry's shoulder, and Ron who complain at him about how Hedwig tried to turn both of them into pincushion with the last delivery.

That made Big Sister's smile brighten, reminiscence about her past for them to hear. "Don't be so formal, it felt like yesterday, when I was about your age… heh… when we're younger, and before the war escalated…" her face sadden a bit, then she shook those depressing thought aside before any of the teenagers will caught in it, and turned to Harry who just shot an angry snorts at Ron because the redhead, and by extension, Hermione, happened to know that he was being watched during this summer by the member of this 'Order of Phoenix' and do not tell a thing to him! Then the arguments between the trios follow, something which Hedwig disapprove of and flew back to the corner of the room while no one is watching, along with Pigwidgeon.

Seeing that he get caught in an argument with Ron and Hermione, a very loudly one she must added, without sign that it'll stop soon, Big Sis decided to grabbed Harry's shoulder from behind, a crackle of electricity could be heard, a small blue flash of sparks can be seen between her hand and his shoulder. And Harry nearly jumped while let out a cries of pain, turning his attention to his assailant instantly, which prompt the girl in question to yell at him point-blank. "Kid, Are you still with me!?"

"What was that for Sis? Is that a way you ask anyone for attention?" Harry asks, rubbing his shoulder that just felt the shock and still has small burn on the cloth at that spot.

Big Sis frowned, both hands on her hip and eyeing him with displeasure. "Oh? And you lashed out at your friends for following order from someone who obliviously can expel them out of their school should he felt like it is a just cause for them to receive this treatment from you huh, Kid?"

Harry nearly choked at those words, he doubt that Dumbledore would do that considered what he had done in the pasts and how much he care for his students, however, looking back at Hermione and Ron, who clearly look at him apologetically, he started to regret his action, especially when he remembered that Hermione is someone who will following books and authority to the letter unless it was extreme circumstance, while Ron, well, he just met his mother a while ago, he now sure that even if the redhead is a bit rebellious than Hermione, but he also has to obeyed his mother too.

Once the rage inside him subsided, Harry apologized to both of them. "I'm sorry… a lot happened, and I…" he trailed off, not sure what to say to make amend with his best friends.

The girl and the boy just simply nod sadly, small drop of tears on their eyes, and that was enough for him. He nodded back and repeats his words again "I'm sorry."

Suddenly, his Big Sis slapped him at his back, nearly make him fallen over the dusty floor, not by her force, but by his instinct thinking that she's about to shock him again, he then retort back. "What's that for Big Sis? I thought you're going to shock me again!"

"Hey, hey, stop being such a brooding boy, kid, now that the problem has been resolve, would you kindly introduce me to them?" She spoke playfully, clearly not care about Harry's rants, looking at Ron and Hermione who's staring at her with interest, while her hands still has sparks crackle between fingers, which made everyone in the room gulped at that dangerous sight.

But before anyone could introduce themselves, two loud crack sounds coupled with two identical figures of redhead teenage boys slightly older than Ron appeared from thin air in the middle of the room, causing Ron to jumped back and Hermione to sigh at the sight of the twin.

"Fred, George…" she called them out. "Please stop doing that…"

But her word fall on deaf ears as the Weasley twin instead interested in the newcomers, particularly the new face they never seen before, or the girl with purple hair and eyes…

"Whoa, check this little girl out, Fred!" The first one who was nearest to her called out to his twin after he finished greeting Harry and taught him that he shouldn't let all of his anger building up and not letting them out, or something along that line, then try to starts a conversation with a new lady in the house. "Nice jacket, young lady, even with that strange emblems etching there." He pointed at the bottom of her white jacket.

Now that he mentioned it, Harry take a glance at the symbols on the jacket in question that he overlooked for this whole time, they're not dark marks, but looks like a deep violet kite shield with staff and a crystal ball over it pointing upward, was this jacket a remainders from the war his Big Sister fought in? Which he wouldn't be surprised if it was one, since those symbols on it are practically screamed military. He makes a mental note to ask her about it later.

The twin quickly follows up with a mockery of a gentleman bow in front of the girl and asks her who she was, which send Big Sis into a giggle, and gotten interrupted again when the door flung open, revealing another redhead, this time a girl peeking inside the room at the amusing performance of both her older twin brothers.

She then noticed the raven haired boy and greets him. "Oh, hello, Harry, I thought that was your voice earlier, really good timing to wake me up, hmm…" She then looks at the unfamiliar face, which blinked at her in return. "I never see her anywhere before, who is she?"

"That's what we're about to ask her, Ginny…" one of the twin, Fred maybe, replied, and another one, adds on his sentence while slapping at the raven haired boy's shoulder. "Somehow, this Harry seems to call her Big Sis, but truth to be told, the 'Big' part is a massive overstatement, she's barely his height, not to mention..." he trailed off, eyes shot at his younger sister with a dirty look which made the girl blushed bright red, along with Hermione who shot the twin a disapproving look as well.

A tapping sound of foot hitting the floor repeatedly could be heard from the only purple haired girl in the group, looking at the origin, they saw that the girl seems not taking the joke that the twin made very well, she was putting up a smile that is quite more scary than cute, her arms crossed, and those whirlwind laced with small sparks that suddenly formed up out of nowhere around her like a barrier basically sealed the deal that she's serious!

Her eyes then glared at the twins, somehow made both offenders genuinely shivered in fear, then she states in a dangerously polite tone added up the 'dangerous' part of the scale further. "Well, you got quite a tongue aren't you? Oh, and excuse me for being flat!"

The twin twirled in place, looks like trying to apparate away, but suddenly they're frozen mid-turn, except only their eyes which still rolling wildly, trying to figure out what happened to them, only to caught sight of various faint line of lights binding at various parts of their bodies, crisscrossing, splitting, and conversing to formed a small web and circle around each of them with one strand tracking back to the purple haired girl's right hand like a puppet strings.

Then Big Sister leans closer to both teens who struggling haplessly to leave, speaks to them softly… dangerously soft… "You're lucky, Kids, for if I was about your age when you insulted me with that… word…, I would've flies in rage and fry both of you…" her free hand suddenly crackled with lighting jolting back and forth between it and another that was holding the teen captive, yet the lightning did not travel along the light line to those teens, making everyone gulped. "…But now, I'm mad because is that dirty mouth of yours tainting a young innocent girl…" She glanced at Ginny, who's blushing bright red, and then she notices something...

Her well-honed instinct told her to spared one look around the room at that words, and noticed that all the teens present there already has their wands out, pointing at her, albeit shakily in case of Harry Potter, as he clearly do not want to do her harm, and Ginny also started to put out her wand as well.

She sighed, and then releases the twin from her spell, but without a parting threat. "Considered yourself lucky, kids… that even your sister still wanted to forgive you and help you, and that you're not in a warzone, where such slip of tongue can, and will land you in a summary execution if not careful, talent individual be damned!" Then she moved toward the wall next to the door and lean there, eyes closed.

"Wandless… casting…" Ginny muttered breaking the silence while pocketing her wand, clearly did not believed what she just saw.

"You forget the part that she did not even spoke incantation, casting multiple spells simultaneously, which every single book out there stated to be outright impossible, especially to do all of that in concerts of each other." Hermione, the bookworm as she is, added up even more facts that put the girl in an even more terrifying territory, while she herself clearly impressed, judging from the look of her eyes.

"Wicked!" Ron exclaimed, clearly impressed at the display, at the expense of his brothers of course, which both of them snorts back in response.

"Yeah right, nearly scared me to death, Gred?"

"You sure as hell I'm feeling the same thing Forge." Then they glared at their younger brother, speaks simultaneously. "Oh yeah, that's right, laugh it up Ronnie, not even remorse of not lending your innocent big brothers in time of need, why did you change like that? or you just have a crush on her?"

"Hey, stop bullying someone who can't fight back in my sight please… oh, and don't gossiping about someone right next to you as well…" Big Sis spoke up, eyes snapped open. "…speaking of which, Harry…" She turned toward the Boy-Who-Lived, garnered his attention. "…mind introducing them?"

Suddenly all the banters, all the brothers quarreling, came to a halt when those word left her mouth, everyone stood attention to the girl. Coughing slightly, Harry then begins by walking right up to two of his best friends and introduces them first. "This is Ron Weasley." The redhead nodded a little, smile at the girl "This is Hermione Granger, both of them are in Gryffindor the same year as me, the friends I'm talking about back at Dursleys' you know..."

"A pleasure to meet you… Miss…" Hermione greet the girl, only to trail off when she realized that the girl… Big Sister, never once told them her name, and Harry, for all that he seems to fond of her despite met once when he was eight, never once told it either, so they're basically left in the dark about her name, something which made a dark parts of Harry's mind satisfied a little that he at least hold some secret and information away, from them, although it won't last long...

Big Sister takes one look at the reluctant expression on the bushy-haired girl's face and noticed what was wrong immediately, so she glared at Harry and mutters. "So, you never once told them what my name was huh, Kid, Why?"

Harry, of course, knows that these questions will soon coming from her, shrugged. "As you once said back at the Dursleys house, I cannot spell your name without somehow butchered it beyond recognition, and during all these time, I thought that you'll never come back so you're some sort of a tales of my childhood for them, not someone that they might meet one day in the future considered how you made your hometown's stories so bleak and hopeless that no one will expect you to come back alive."

As if they were all in agreement, Ron, Hermione, Fred, George, and even Ginny all nodded to confirm that what Harry told her was true, made the girl sighed in resignation, holding both hands up front. "All right, my fault for being pessimistic about my homeland, oh, and you got quite a tongue there, Kid." She remarked at Harry affectionately in the last word, smiling briefly, before introduce herself in turn.

"My name is Aisha, please to meet you all as well." She then politely bows a little to all of them.

And the result is, as she predicted, Fred and George greeted her with 'Aesir', while Ginny called her 'I-Sa', Ron worked his mouth without sound, which make Aisha sighed at the display.

"It's been a pleasure to meet you as well, Miss Aisha." Hermione is the only one who bowed back and spoke her name correctly, even if she knows not if this is the way of greeting of Aisha's homeland or not, which reminded her of some unanswered question that plagued her since Harry told her about Aisha, his 'Big Sister', and with the opportunity to fulfill that knowledge in front of her, it was natural that she will asks, albeit reluctantly. "Miss Aisha?"

Aisha waved her right hand at Hermione, shaking her head. "Just Aisha is fine, because I'm going to called you by your name as well, what is it Hermione?"

"Um, okay, Aisha…" Hermione's looked down at her feet, clearly embarrassed, before gathered up courage and asks her, along with excessive explanation of what she knew up until now. "If you don't mind, I'm studied a lot about wizarding world and culture in magical communities across the globe, including those oversea, not just in Britain here and…" She trailed off, looking at another girl.

"And what?" Aisha tilted her head a little, suspiciously looking back at the girl who suddenly silent.

"…and I cannot found any country or area, or community where you might possibly come from at all." She finally spoke out, albeit reluctantly "I didn't mean to say that your homeland did not exist… it's just that I don't know if…"

Aisha catch on what the girl meant and finish it for her. "You don't know if my homeland actually existed or not, where they are, and what kind of magic I used that do not require that stick of your to cast, right?"

Even if she was upset by being called 'Little girl' by someone who look about her age, Hermione was sure to hide it very well, that, or because she knew that, the girl before her was actually older than Percy Weasley, who just graduated from Hogwarts last year at age seventeen. Thus the only reaction she did is nodding her head, confirming Aisha's question, as well as the rest of the teens who also eager to know about the girl, especially after the mysterious magic style displayed earlier that spiked up their interest even more.

However, before Aisha could answer Hermione, and by extension, everyone else that question. Footstep from outside can be heard coming from a floor below, and a few moment later, the door flung opened once more, this time, Lupin, Kingsley, Sirius and Mrs. Weasley all lined up standing at the hallway looking at the group of teenagers (And one adult that looks like teenager, in case of Aisha.) with a little serious expression on Kingsley's face directing toward the purple haired magic user.

Mrs. Weasley is the first one to spoke. "Everyone, the meeting just ended, let go downstairs and have supper, everyone wanted to have a word with you Harry…" She then looked at Aisha worryingly "And you as well Miss 'Big Sister' they wanted to speak with you."

That made Fred and George burst out into laughter in an instant, make every single adult there confused to what is going on, while other teens keep silent, nervously not wanted to help explain what made both twin turned out like that, until Mrs. Weasley cough up and gave them both a death glare, which effectively stopped them cold, albeit they still mock her by acting as if her stare was that of a Basilisk and they're about to die, which made even Lupin and Sirius nearly laugh out, had not because of a warning glare from the Mother of all Weasley sibling.

Aisha chuckle at the sight, then explains. "My name's Aisha, Ma'am, sorry for my rudeness to not introduce myself earlier, seeing that you all caught up in… business…" of course, she's referring to the meeting with Dumbledore and those Orders of… whatever, then follow up with another question. "Oh, will this 'Dumbledore' present there in the supper as well? It looks like this little Harry…" she slapped his shoulder once nearly make Harry jumped. "…wanted to have a word with him, or that's what he told me."

"Pleasure to meet you as well Miss Ae… Sar…" Mrs. Weasley, like her sons and daughter, have trouble pronounce her name as well, sending the twin into laughter again.

"Ai…Sha… Ma'am" Aisha repeats her name slowly and politely.

"Oh, well, Aisha, nice to meet you." At least, Mrs. Weasley got it right the second try, then she proceed to answer the earlier question. "As for Dumbledore, I'm sorry dear, but he has a job to attend to, along with Professor Snape, as well as every other Order members are also quite busy as well, so it's mostly us here, Moody, Bill and Nymphadora are downstairs preparing food as we speak."

"…" Every Weasleys, save for Mr. and Mrs. Weasley snorted at the idea of Moody preparing food, because, after living here for the past month, they came to know him quite well enough that the only reason Mad-eye (The Real one that is) still here instead of going out doing whatever mission the Order had for him was that he wanted to interrogate their newest guest more than anything.

A quick glance at everyone gathered around here is more than enough to tell Aisha about what they've planned for her, or rather, what Moody planned for her, but, considering her options, she is now in a new land and in some sort of organization that required secrecy, it would be stupid not to obliged to some requests, that, and as long as they don't pries much about her or her homeland or tries to make Harry doing something dangerous without justified reason, then she is fine with it.

Thus she simply looks at those teens, claps her hands and replies. "Then what are we waiting for? Better get them eat and go to sleep, it's…" She looks at the pocket watch she carried in her jacket, then chuckle. "Oh, my, it's more like a midnight snacks than a supper now…" She then showed them her pocket watch, which shown 11:40 P.M. on its panel.

Everyone suddenly felt their stomach grumbling noise, especially Harry who hadn't eat since his Big Sis asked him to sleep in the afternoon, now he wanted nothing more than a hot meal and a nice, soft bed to sleep afterward even he just slept the entire afternoon beforehand, after all, discounting all the magic he has, he's still human, not an owl, and definitely not veteran soldier like Big Sister Aisha, so sleeping at night is pretty much a basic instinct and need for him.

Well, if you factored in the burning desires to know more about what's going on here, it is more than enough to keep The-Boy-Who-Lived awake until he get what he wanted to, and for that, the faster the supper begin, the faster he could interrogate answer from all adults here.

So, with everyone in agreement and already hungry, they all descend down the staircases and move toward the dining room, where once the meeting took place a few moments before.

Author Note: Well, I thought of delay revealing Big Sis true name out for another chapter or two, but when actually tried to write it, turned out that doing so would stretch too much suspension of disbelieve as to why no one will ask her about it.

So, with the name revealed, I think some may get the idea already as who she is, and thus, depend on if someone speak it out loud in the reviews or not, this fanfic will move to the Crossover Section in the next time I update it, or remain here for another chapter if no one still can't figure it out yet.

Rate and Review as you see fit, especially if you saw a mistake of my parts, you should tell me for the sake of improvement, see you again next time.
