Summary: Buffy gets a letter inviting her to help teach at Hogwarts. Dumbledore tells her about the fight with Voldemort, and she agrees to help protect Harry Potter. While there, she learns things about herself that she never knew, and she finds a way to live. Meanwhile, Sirius Black can't stop thinking about the blonde Slayer that has suddenly invaded his life.

Disclaimer: I don't own any of them. Buffy goes to Whedon, and Harry and everybody in the Potter-verse go to Rowling. If you don't recognize anyone, they're probably mine. I do own the plot, though. Don't sue. Please.

Author's Note: Thanks to Dreamer Child, CharmedChick, Ivy Tearen, Sabia, vampy the chosen one, Ella, kitty minky, Catlimere, Renna, Stix89, clcountry , and bee3 for reviewing!!

Dreamer Child: when I wrote that part about Buffy and Sirius, I was thinking that too. But, I think Buffy has realized that you can't beat around the bush. As for Faith? She'd be like "You're so hot, I could eat you right up." I'm glad that's not what Buffy's like.

Sabia: I don't believe Buffy would have killed herself if she didn't have Spike. She had to live for her sister, and she knew that. Hopefully, coming to Hogwarts will help her live.

Vampy the chosen one: I don't mind that you just like to review, and not critique. Thanks for the kind words!!

Renna: what's up with Harry and Buffy? You'll have to find out….

Clcountry: Thank you for being such a sweetie. You're now one of my favorite reviewers!!!

'Lay beside me

Under wicked sky

The black of day

Dark of night.'

-Metallica "The Unforgiving 2"

When Buffy woke up she was on a floating stretcher. Looking around, she saw the student whose head she had entered in a similar position. Sirius Black was walking next to him, casting anxious glances at his prone, unmoving form. The redhead and brunette who were sitting next to the student were doing the same thing. Professor's Dumbledore and McGonagall were also there. As were all the other professors Buffy had seen in the Great Hall.

Groaning, she felt the throbbing pain in her head and suddenly started wishing for aspirin. Her groan attracted the attention of all that silently walked with them. As they crowded around her, (sans Sirius and the two students), she asked, "Where are we going?"

"To the medi-wing," the Headmaster answered. Seeing her expression, he explained. "It's like a hospital."

Alarmed, Buffy rolled out of the stretcher and everyone stared. "No! No hospitals. I'm fine. Perfectly fine. See, no cuts, bruises, or broken bones. I feel great! Just… fine and dandy. Really. So, we don't need a hospital or doctor because I'm fine. 10 toes and 10 fingers. Two arms, two legs, a head, a nose, mouth, two eyes, two ears, and hair. All body parts are intact. No hospital. Please?" She hastily pleaded.

"Miss Summers, you need to go to the medical wing so Poppy can check you out. Now, come on." Professor Dumbledore said sternly.

"No. I am not going to a hospital. You'll have to make me." Buffy said firmly. She stubbornly held her chin up and folder her arms across her chest. Sighing, Dumbledore nodded his head at Severus Snape, who walked forward and grabbed the small woman by the arms.

"Hey! What are you doing? Put me down! Now! Hey, come one. Don't you dare! No! Put me down this instant! What do you think you're doing? Dumbledore, call him off! Now! Don't make me do something drastic!" Buffy threatened as she was suddenly scooped up by a man bigger than Angel himself. He had shoulder length, greasy black hair and he looked slightly sinister.

"I'm sorry Miss Summers, but this necessary. We know you're fine, but just in case, we need you to be looked at."

"I hate you," was all she said as she glared at Dumbledore and the man who carried her.

Chuckling, Dumbledore said, "You'll get over it, I'm sure."

The paused at a door and walked in.

****************(Ten minutes earlier)*******************

Madame Pomfrey hummed while she straightened up the medical wing for the new school year. This year was sure to be a hectic one, what with You-Know-Who back again and Harry Potter and his two friends, Ronald Weasley and Hermione Granger, still in school.

Poppy prided her job as Hogwarts nurse. Her specialty was potions. And she had a feeling she would be needing a lot this year. Still humming, she turned around when she heard the door creak open. Stopping mid-chorus, she said a startled "Oh, dear!"

"Yeah, you British people sure are fond of saying 'oh dear!' aren't ya?

************

"So, now that Poppy has declared you well, why don't we get down to business?" Dumbledore asked. Buffy sighed, shifting on the bed she was currently confined to.

When they had gotten looked over, Madame Pomfrey had diagnosed them to be healthy, except for the bumps on their heads, and told her and the student, Harry Potter she now knew, to lay down and rest. Buffy had protested. Loudly. She was still mad about being carried by mean looking guy. But she was talked into it, and that was only because they had promised her chocolate. And she still hadn't gotten it.

"First things first. Can I have my chocolate now? Please?" She asked. When a good sized chunk was given to her, Buffy motioned for Dumbledore to begin.

"Let me make introductions first. Miss Summers, this is Severus Snape," he pointed at mean looking guy, "Professor of Potions. Professor Sprout, Professor of Herbology," a woman with clumps of dirt in her hair, "Filius Flitwick, Professor of Charms," a teeny-tiny man with wiry hair, "And you've met Professor's McGonagall and Black. This is Professor Vector of Arithmancy and Professor Sinistra, he teaches Astronomy. That is Harry Potter, Ronald Weasley, and Hermione Granger. They are in their fifth year. Now, would you two mind explaining about what happened earlier."

Harry and Buffy looked at each other. Finally, Buffy said, "I looked into his past, I think."

"What did you see?" Harry asked curiously, but also dreading the answer.

"A house. Then I was in the house. I… saw a man on the ground. He looked… dead. Then I saw a woman younger than me. About 20 years old. She had a baby and was crying. I turned around and saw this… person in a black robe, holding this stick thing. The woman started screaming, "No! Not Harry! No… not Harry!" Then the robed guy did some hocus-pocus, and then there was green light and I woke up."

"Harry?" Dumbledore asked a shaken Harry.

"Yes, sir?" Harry answered, staring at Buffy.

"What did you see?"

"I… I saw a tower. The sun was rising and I turned around. Professor Summers was there with a girl my age. She had dark brown hair." At this, Professor Summers had gone really pale and her eyes had filled up with tears. Harry watched her while he talked. "They were both crying. The… the girl was bleeding and Professor Summers was telling her something. Then Professor Summers turned around and ran to the edge of the tower and jumped into a swirling mass of white and blue sparks. The girl… she was screaming, "Buffy! Please… no!" There was a white light, and then I woke up here… What is going on?" That last part was directed at Professor Summers.

Buffy could feel the tears running down her face. They felt foreign because she hadn't cried in years. She lifted her hand to her face and it came back wet. She stared at it in astonishment. Curling a hand into a fist, she looked up. It had been so long since she'd spoken about what happened out loud.

Sirius was confused. What he had heard from both Harry and Miss Summers was unbelievable. How had this American girl seen what had happened 14 years ago? And what was Harry talking about? Miss Summers jumping off a tower into white and blue sparks? He watched as she touched her tear-stained face and stared at her hand in astonishment, like crying was all too new to her. What was going on here?

"This is all very complicated, and I am sorry to say that I can tell you no more. At least not now. Miss Summers is here for a reason, and that is all you can know. For now. So, why doesn't everybody just head off to your dorms and rooms? Oh, and Mr. Potter, Mr. Weasley, and Miss Granger, could you please keep this to yourselves?" They nodded. "Good. And good night. We will see you in the morning."

"Good night, Professors." They said in unison. When the room had cleared of all but Buffy, Sirius, and Dumbledore, he spoke again. "Sirius, would you mind showing Miss Summers to her room? It's behind the Stone Angel."

"Sure Albus. Good night."

"Good night, Sirius. Good night Miss Summers." He winked and walked out of the room.

"Good night, Double Door." Buffy said. She didn't even protest as Sirius helped her off the bed and steered her out of the room. She really didn't feel like getting lost again. She sighed softly.

"Well, lead on kind sir," Buffy said, motioning helplessly.

Sirius didn't say anything. Instead, he just walked towards the stairs, Miss Summers trailing behind him. Inside, he was thinking 'Double Door? Okay.'

The walk to the Stone Angel was silent. Finally they got there. Miss Summers turned to Sirius with a small grin on her face, eyes twinkling with mischief, and he felt his breath catch in his throat. She looked stunning.

Buffy didn't notice a change is Sirius. Instead, she turned back to the statue and said, "Chocolate Kisses." The Stone Angel swung open silently. Buffy turned to Sirius again. Nothing was said for a minute.

Then, "Chocolate Kisses?" Sirius asked, smiling slightly.

"Yeah. Chocolate is yummy, and kisses are yummier. Therefore, Chocolate Kisses. Double your yum, double your fun." Miss Summers explained.

"I'll keep that in mind."

Buffy smiled. Cute and funny! Wow! Sirius stopped breathing altogether. She looked even more beautiful, if that was possible, when she smiled like that. "Well," that came out a little too high-pitched. Clearing his throat, he began again. "Well, I will see you tomorrow in class, which begins at 10:30. Good night."

"Good night, Sirius."

The stood there staring at each other, slowly leaning closer. Then, abruptly, they both turned around. Buffy hurried into her room, the statue closing behind her, as Sirius practically ran to his room. When he got to his room, he said, "Slayer" to the painting, proceeding to go in when it opened.

Sirius had always had a fascination with Vampire Slayers, ever since he had read the ancient tome Vampyr in his third year. It was fascinating how this young girl, all by herself, fought vampires and demons. It was extraordinary how she had the strength, speed, and ability to save the world. And utterly sad that none of them lived past the age of 21.
