Hey, people. Thought I'd update, since you're all so nice. Might be a couple of weeks before the next one, though. Okay?

By the way, have you seen the new Harry Potter film? I mean, there were a couple of things that weren't explained, but if you shy away from the books, it was a brilliant film! Even with the books, it's still great! JKR says it's the best film so far, and who are we to doubt the author whose work is being used?

Answers to reviews at end. Onto the story!

Chapter 2

"Giles! I've found one of them!" A voice yelled through the large manor house.

"This place is amazing." Harry Potter commented. "Much nicer than Malfoy Manor, but then I blew that up."

Buffy shot him a funny look and entered the Conference Room. The others were all sat there. Young, chestnut-haired Dawn, brown, slightly greying haired Giles, black-haired Xander with his eye patch, blonde, skinny Andrew (his room was by the kitchens since he had proven a good cook), dark-haired Faith and shaven, dark-skinned Robin Wood.

"Hi guys." Buffy grinned.

"Buffy, how was patrollin'?" Faith asked.

"London's got as many vamps as Sunnyhell." Buffy replied.

"Wicked." Faith grinned.

At that moment, someone else appeared. A grey-eyed redhead with a cheery expression entered, Harry could sense the power emanating from her.

"Willow!" Xander exclaimed as he and Buffy went to hug her.

"Hi guys, I – uh – there's something you need to know." She looked sad.

"What happened?" Buffy asked, worried.

"Me 'n' Kennedy. We broke up."

"Oh, why?" Buffy asked. "You two were great together!"

"It just... She still had that thing about magic. Even though the thing with the scythe wiped me clean..."

"Oh, Will, that's too bad." Buffy hugged her friend.

"Yeah. Yeah. Maybe I should go back to guys." Willow gave a half-hearted grin.

"Well, whatever you do, don't turn into a demon magnet like me." Xander joked.

"Um, Buffy, who's our guest?" Giles asked, looking at the young man who was leaning languidly against the wall, playing with something in his hands.

"Well, why doesn't our guest explain?" Buffy asked, sitting down.

"Well, I can hardly tell all of you who I am. You're not like me... Except..." He frowned, re-examining Buffy, Willow and Dawn. "You three. You have power. Magic power."

Buffy shook her head, as did Dawn. "Magic free here."

Willow frowned. "How do you know that?"

"I can sense it. Ever since Sixth-year..." His voice trailed off.

"What's your name?" Giles asked.

"Potter. Harry Potter." He replied.

Buffy giggled. He frowned. She grinned at him. "Sorry, but that seemed so much like 'Bond, James Bond'."

He grinned. "Did a little, didn't it? So what about you?"

"I told you, I'm Buffy Summers." She began pointing to the others. "Dawn, my little sister. Xander, Willow, my two best friends. Faith, my sister Slayer. Giles, my Watcher. Robin, Faith's – dare I say it – boyfriend and my ex-boss. Andrew, my... well, he's just sort of there. Cook and researcher, I guess."

Andrew gave a shy smile. "I'm redeeming myself. I killed someone."

Harry shrugged. "Haven't we all."

Buffy stared at him. "You killed someone?"

"Well, lots actually. Must be at least a hundred odd vampires by now. A number of assorted demons. Oh, and of course, Tom Riddle. Only one who was actually close to human, and I wouldn't say there was much left."

"Why'd you kill him?"

"Evil. Trying to purge the world. World domination. Murderer and torturer of countless wit... people. Including my parents and my best friend." (A/N: Major hint there!)

"That's awful."

"Yeah. But at least I'm still human. It had to be me who killed him. Anyway, enough about me. You're the Slayer?" He asked pointedly.

"You've heard of us?"

"Yes. Vampires kept saying that I reeked of the Slayer's power, but couldn't be one since I was male. Hermione and I looked it up. One girl born into each generation to fight the demons, blah, blah, blah. Oldest Slayer lived to twenty-five, lasted for ten years. Youngest was killed four days after finding out about her destiny. She was fifteen. Of course, it can't be true about the one girl bit, can it? Because otherwise you'd have to wait forever for a new Slayer and the demons would overrun the Earth."

"You did a lot of research, didn't you?"

"I finally succumbed to Hermione's nagging. I needed to do well in school to get my job. It did work."

"Well, you were mostly right. We kinda changed the 'one girl' bit. Every girl born with the potential to be Slayer, now is a Slayer. Willow did it so we could defeat the First a while back."

"That was the disruption in April?"

"Yes, how did you...?"

"My kind know of the Hellmouth and it's demons. However, we rarely come across them. They prefer Muggle areas. Muggles are blind to them."

"Muggles?"

"People who are unlike us. Some of you are, but I've a feeling you aren't normal Muggles."

Willow shook her head. "Buffy and Faith are Slayers. The original Slayers, actually. Buffy died, but was revived. That called Kendra, but she died, calling Faith. The other Slayers who live here are the remains of the potential Slayers whom the Bringers were killing so as to eliminate the Slayer line."

Harry nodded. "What about you, and Dawn, is it? I can sense power in you two."

"I, er, I'm a witch."

Harry frowned. "How can you be? You do not use a wand..."

"Wiccan witch." Dawn clarified.

"Ah. And you?"

Buffy looked awkward. "She – uh – she is the Key." For some reason she felt she could trust him.

Harry's eyes widened. "Holy crap." He stated.

"What did you say?" Buffy commented.

"Your eyes... Her eyes... Key... You were put into human form?" Dawn nodded. "Damn, I'm going to kill Trelawney."

"Who's Trelawney?"

"My ex-Divination teacher. She spends most of her time making up stupid predictions, especially about death and bad luck. However, she does actually have some Sight, though more about little things. Once in a while, she predicts something big. Two have so far come true. She made a third not long ago about a Key, a Slayer and a Hunter. That vampire said the same."

"Hunter?" Giles asked.

Harry nodded. "Apparently, that's my nickname with the Undead."

"It's no nickname. The Hunter is even more legendary than the Slayer, though thought to be a myth. Strength, heightened senses, speed, stamina, suppleness, often able to feel the strong emotions or needs of those close to him. Often has magic." Giles frowned. "Who are you, what is 'your kind'?"

"I'm Harry Potter, Boy Who Lived. I'm a wizard and an Auror. My kind is witches and wizards. We are different to Wiccans. We use wands and incantations. Our magic comes from inside ourselves, not the world around us. It's less... intoxicating than Wiccan magic, so I am told. Wizards and witches use magic for everything. Which is why I beat Tom Riddle." Harry grinned. "He underestimated Muggle ways."

"How did you kill him?" Buffy asked.

"I drove the Sword of Gryffindor through his chest. Slytherin never had a sword and never passed it on to his Heir, which was Tom. I happened to be Gryffindor's Heir, but since I had some very Slytherin traits, I understood Tom better than he thought."

"What traits?" Buffy wanted to know. She didn't understand who Slytherin or Gryffindor were, but got the idea that Slytherin wasn't a great guy.

"Ambition, cunning, disregard for the rules, which I might say also comes from my dad. I'm also a Parselmouth, which Tom accidentally passed on to me when he tried to kill me the first time."

"What's a Parselmouth?" Dawn asked.

"Someone who can talk to snakes." Harry replied.

"Cool!" Xander grinned.

"Who is this Tom you keep talking about?" Giles frowned.

"Tom Riddle, also known as Voldemort. Evil wizard, wanted me dead, wanted to take over the world and kill all Muggles and non-pureblood wizards, which is very hypocritical since his daddy was a Muggle."

"You defeated Voldemort?" Giles checked.

Harry nodded. "Yeah, why?"

"Because I now remember why your name seems familiar! The Coven told me about a powerful evil wizard named Voldemort who greatly upset the balance four years ago when he used necromancy to fight. They said that he was afraid of two wizards only. One they didn't know the name of..."

"Albus Dumbledore." Harry replied. "He's the only wizard Tom was afraid of."

Giles shook his head. "No, there was a second. They said that he was also afraid of a child, by then a man, who held a power in such abundance that he could not defeat it. They said his name was Harry James Potter."

Harry shrugged. "He was only afraid of the prophecy because he never found out all of what it said. As for power... I don't believe I was any more powerful than him."

"Then how did you defeat him?"

"I used Muggle means against a magical problem."

Xander grinned. "You're just like Buffy, she's always arguing with Giles."

Harry grinned. "For me it's Dumbledore. I completed wrecked his office at the end of Fifth-year."

"Did you burn down your high school gym?" Buffy asked.

He shook his head. "Nah, we don't have a gym. I did manage to destroy the Quidditch pitch in Sixth-year. I can tell you, people were not pleased that a crater stood where it had been. Thank God for magic."

"I blew up my next high school." Buffy informed him.

"Blew up Malfoy manor."

"My last house now lies at the bottom of what is now called Sunnydale Gulf." (A/N: It was at the seaside. Say the sea flowed in.)

"Actually, Buffy, that was Spike." Xander pointed out.

Buffy pouted. "Fine."

"I should introduce you to the twins. They created a swamp on one of our corridors." Harry grinned.

They continued to exchange stories, Harry finally explaining all about Voldemort and wizarding world, while Buffy did the same for the First and the demonic world.

"I'm sorry, Buffy, Dawn, there's something about you two that is just too much. I think you might be witches. My kind." Harry informed them.

"H-how do you know?" Buffy asked.

"I can sense it."

"How?"

"I don't know. I've been able to do it since Sixth-year. I don't know what happened, but when I turned sixteen I seemed to get better senses and stuff." Harry explained. (A/N: Before anyone suggests it, this isn't a super-power Harry story. He's powerful, but doesn't realise how much.)

"So what do you propose?"

"We go and see Dumbledore." Harry replied.

"Erm, I think there's something you ought to see first." Buffy informed him and opened the hidden door.

Andrew looked surprised. "What's up there?" He wanted to know.

"Secret passageways, staircases and our rooms." Buffy replied. "You're the only other person who knows. Don't tell anyone, don't go up there unless necessary."

Andrew nodded. "Okay."

Buffy, Dawn and Giles headed up, Harry following. They soon arrived on the corridor at the top of the house.

Harry stared at the door to his room, which was at the far end and opposite Buffy's.

"My name. Why hasn't yours got a surname?" Harry asked.

"We don't know. We figure whatever, or whoever, set this up, just didn't know." Buffy shrugged.

Harry shook his head. "There'll be a reason, these things aren't just forgotten."

He turned the doorknob, whispering a password.

"You already have a password?" Buffy asked.

"Doesn't everyone?"

"We just use keys." Buffy informed him tartly.

"I do, but Hogwarts always uses passwords. And this place reminds me of Hogwarts." Harry opened the door.

The room proved to be similar to the others, themed with red and gold with mahogany wood. He was glad that the red was mostly muted – sometimes it could be too much. He then stared at the photos upon the mantelpiece.

"Who are they?" Buffy asked.

"Those are my parents." Harry pointed to the photo. "And that's Sirius and... Well, I don't know who she is. She looks kinda familiar..."

Buffy frowned. "That's my mother. Why is she...?"

"I don't know." Harry stopped as his eyes went onto the next photo, himself, a girl with curly brown hair and brown eyes and a boy with bright red hair and blue eyes.

"Who are they?"

"Hermione and Ron. My best friends." Harry's voice was thick by now. "That was taken just after graduation. Just before..."

"What happened?"

"Tom killed Ron." Harry stated. (A/N: Ha, ha! That's why he hasn't got a door!) "I've got another copy of this photo."

It was then that Buffy jumped.

"What?"

"They – the photos are moving."

Harry nodded. "Yeah, wizard photos do that. It's one of the best things about them."

"C'mon, you wanted us to see Dumbledore, didn't you?"

Harry nodded, startled.

Then they passed the verse at the other end, by the door.

"Interesting." Harry commented.

Willow came up the stairs.

"What's interesting?" She asked.

"This verse."

Willow read it, her grey eyes unreadable. She then stared at Buffy and Harry.

"Come on."

"What's with the blank door on our side?" Harry wondered.

Buffy shrugged. "No idea. Where exactly are we going?"

"It's a short walk from here. Dumbledore should be there, he often is during the summer."

"Hey, I'm coming too." Willow informed them. "I want to know about this Dumbledore guy."

"Sure. He won't mind. In fact he'll probably be very inquisitive about Wiccan magic." Harry explained.

"Then what're we waiting for?" Buffy asked. "Who's coming?" Willow, Dawn and Giles informed her that they were. "Okay, Xand, you and the others check on the girls, alright?"

Xander nodded. "Sure. And maybe I'll shop for some groceries while I'm at it."

"Good idea. It's, what, eleven, and I don't think any of them have eaten yet. We'll sort everything else some other time. We need to feed them now. We'll see you later. If we're not here tomorrow morning, we'll probably still be with this Dumbledore guy."

Xander nodded. "Okay."

Buffy and the others left, taking light jackets – while it was warm, it was not yet August. They were two weeks into July.

"So, where're we going?"

"It's called Grimmauld Place. Good job we haven't still got the charm on it, or you'd not be able to see it, let alone go in."

It was about a half hour's walk from what Buffy called Slayer Manor – which was on the edges of the middle of London, and absolutely huge – to Gimmauld Place.

"Here we are." Harry grinned.

The house they stood before looked well groomed and was clean and white. A brass doorknocker was in the shape of a phoenix. Harry knocked three times.

Someone opened the door. "Who... Harry! How lovely to see you!" A young redheaded woman stated.

"Nice to see you too, Ginny. Is Dumbledore about?"

"You know full well he is." Ginny scolded. "And besides, he's never too busy to... Who're these people, Harry?"

"Oh, Buffy Summers, her sister Dawn Summers, Rupert Giles and Willow Rosenburg." Harry introduced each one in turn. "It's why I need to see Dumbledore. How's Neville?"

"He's fine. Very fine." Ginny smiled mysteriously.

"What's so funny?" Harry wanted to know. "What're you hiding, Miss Weasley?"

Buffy snickered.

"What?" Ginny asked her.

"Did he propose?" Buffy wanted to know.

Ginny looked taken aback. "How the... Yes, he did."

Harry grinned. "Good guess, Buffy. You guessed from the door, didn't you?"

Buffy nodded. "It's very sweet. Is she related to your friend?"

Harry looked sad for a moment and nodded. "Yes, she's Ron's little sister."

"How did you know Ron?" Ginny asked.

"Saw a picture. We'll probably be seeing you." Buffy explained.

"Where's Dumbledore?" Harry asked.

"In his office. I swear, he doesn't know what sleep is." Ginny informed them as she led them in.

"Neither do I." Harry and Buffy muttered in unison. The others stared.

Ginny narrowed her eyes. "You sure you aren't related? You've got the same eyes. Like your Mum, Harry."

Harry shrugged. "Yeah, whatever." He knocked on Dumbledore's door.

"Come in." A voice stated.

Harry obeyed. Dumbledore was sat inside with Remus Lupin.

"Harry. To what do we owe this pleasure?" Dumbledore asked.

"A certain chance meeting while I was out this evening." Harry began.

"You were hunting again." Remus said sternly.

"Not exactly..."

"Harry, you're going to get yourself killed!"

"Have you seen a vampire lay a hand on me since we blew up Malfoy Manor? No. Anyway, while I was out chasing vampires, I met Buffy." He pointed to the blonde. "Then this vampire got really weird and started saying something about my being the Hunter. And then something about Hunter, Slayer, Key. And true parents being known only to one."

Buffy interrupted. "He said something about one kept, one given away, one created from given's blood. We don't know what it means."

Dumbledore frowned. "Harry, why did you bring them here?"

"Because Buffy and Dawn appear to have magic, our magic. Willow is a Wiccan, and interested in ours. Mr Giles..."

"Just call me Giles, everyone else does." The man interrupted.

"Giles appears to be their version of you. Plus, at their new home, this manor about half an hour's walk away, there's a corridor. It has six doors on each side, each leading to a room. Each is named but for one. One side belongs to them and their group. The other to ours."

"I'd say Buffy and you are seen as the leaders." Willow commented. "You're both at the end."

Harry shrugged, not bothered. "The door that isn't named is on our side."

"Who are named?" Dumbledore asked.

"You two. Hermione. Neville and Ginny are shared. Then there's the other door. I can't work out why it isn't named." Harry frowned.

"Belongs to someone we don't know yet?" Remus suggested.

Buffy frowned. "I'm sorry if this is rude, but... are you a werewolf?"

Remus looked surprised. "Yes, I am. Uh... how did you know?"

"Sensed it. There's something different in your..." Buffy tried to work out the word.

"Aura." Harry supplied.

"Yeah, that."

"One other thing, the rooms seem to be created by magic, but Buffy's and mine don't have surnames." Dawn interrupted.

At that moment, someone burst into the room. They all turned.

It was a tall woman with greying hair, grey-blue eyes and glasses.

"Minerva?" Harry asked.

"I just had to know. When Ginny said..." Minerva McGonagall asked.

"Know what?" Albus Dumbledore frowned.

"You look so much like her. Not one of you has her hair, but your eyes..." Minerva stated.

"What?" Buffy asked.

"You are the Key, aren't you, created from your sister's blood?" McGonagall shot this at Dawn.

"Yes, but..."

"They are they." She stated.

"Who?" Remus asked.

"Harry, Buffy and Dawn are your sisters."

A/N: Ha ha! An evil cliffhanger! And no update for a couple of weeks because of exams! Muahahahahaha! #Sister rushes in with chocolate# Oh, that's much better. Sorry, guys!

Right, to my reviewers – I can't believe I got 16 reviews for the first chapter!

hellmouth princess: My first reviewer on this story! I hope this lives up to expectation! You're hooked already? I feel so loved!

Malli: Glad you like it. I'm trying to make the long-lost relation thing feasible and realistic. Glad you like the pairing, yeah I like it too! I love BtVS/HP crossovers too! That's why I write 'em! Check out my other one, if you like. You might need to search for Tanydwr on 'Search' though!

Chrios: Glad you like it. As you see, Ron's dead. His character just wouldn't fit in this story. As for the pairing, lots of people seem to like it! Yay!

Draco's Slytherin Vampiress: Draco in the story? Draco and Buffy a couple? Um, to be honest I don't like Draco all that much, and I think Buffy may have had her fill of blondes and brunettes. However, she's not had a redheaded boyfriend... Would you settle for Draco being in the story, but being a royal prick? Y'know, he went neutral, or light side, but he's still a rich aristocratic bas... Okay, so I don't like Draco. Actually, there might be some of him though. I can see a confrontation, especially after what Harry has done to Malfoy Manor...

Harry'sGurl: Thanks! #Blushes# Well, Ron's door was answered here. He's dead. But who does the unnamed door belong to?

Claudia: Glad you like the magic house, I'm kind of playing on childhood wishes here. Technically, at sixteen, I'm not a child any longer. How unfair! Anyway, didn't know about the other story, but there's lots of stories with similar titles out there. Hope you weren't disappointed! But I can't change the title now!

Ebiletha: It's good? And it's different? That's great! Thanks! Those were my main criteria! I'm trying to make it a more original 'Buffy/Harry has a long lost sibling' story. From what is revealed in the fifth book, I can't see James and Lily having a child during sixth or seventh year. Doesn't mean those stories are bad though. I like 'em!

BrokenSkye: What do you mean 'Er... okay'? As for the nickname, that was me having a bit of fun (and probably Neville or Ginny!). Glad you like it though!

Sabia: Glad you like the rhyme. That was carefully thought out in two minutes. Sometimes they just come to me!

Anne-Janet: Well, nearly everybody got a room but Ron...

meenyrocks: Yup, I'm afraid Ron died. He refused to comply with what I told him! So I shot him and marked him as dead in the story. Aren't I nice? #Sister moves away slowly at realising Tanydwr thinks of characters as alive and talking to her#

And to manticore-gurl071134, Lolly6, SilverKinght7, Allianna and polgarathesorceress2, thanks! Here's your update!

Now, the unnamed door? Anyone want to guess who it belongs to? It isn't revealed until the end of Chapter 5, so there's a couple of chapters' leeway. Review to say who you think it is!

That's all for now.

Ta ta! Sorry, need more chocolate!

Lol, Tanydwr
