Title: Bound by Loyalty

Rating: PG-13

Spoilers: Harry Potter- Pretty much books 1-4

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 Tanydwr, JC6, Hinomi, Sabia, clcountry, LizaGirl, dsaf, immortalwizardelf-fan, vampy the chosen one, Renna, WaterNaiad13, Stix89, and even Raven for reviewing.

Tanydwr- Well, Lily and James graduated at around 17, and I'm thinking they died at 19, making Harry 1. 14 years later, and Sirius is 33. Buffy is 25. I'm not sure the SG will show up. Maybe for a few chapters, but this is mostly a Buffy centered fic. Thanks for reviewing.

JC6- Thanks for the longer review.

Sabia- I have a little problem with apostrophes. I hate them, they hate me.

Clcountry- I might have the SG for a few chapters, but they don't exactly fit in this story.

Renna- Buffy didn't want to hurt Snape, because despite what people say about him, he is human. And she was still a bit woozy.

And this is for Raven: first of all, Buffy MUST go because of her dream. Did you read the beginning? She had a dream of people dying. And I did say that she also wanted to go because she wanted to help the wizarding world. Who cares if Sirius has dark brown eyes? In my story, they're green. I know 17 is graduated, not 19. When did I say that? And they weren't killed at 20/21. In my story, they were married at 18, and they had Harry. He was one when they died, making them 19. And in my story, Voldemort is after Giles' time.

Yes, two hours from Ca. to Scotland. How? Because I said so, that's how. So I made a slight mistake saying that Hagrid had class the next day. Everyone makes mistakes. How did Buffy get lost? Well, maybe Dumbledore thought she'd be able to make it to the Great Hall by herself. I don't know. Use your imagination. She didn't explore because Dumbledore asked her to stay in her room. If she would have left, someone would have most likely saw her. Buffy's watch worked because I said it did.

Buffy was a little distracted when Snape picked her up. She didn't struggle because she didn't want to hurt him, and maybe she was dizzy. I'll "get to the good stuff" if I want to. I appreciate your reviewing and all that, but I don't appreciate the way you nit-pick every single detail of my story. It's okay if you catch me on the major mistakes, but honestly, is anyone else out there calculating Giles' age to when Voldemort was around? Is anyone else going "Oh no! Sirius' eyes are brown, not green! The world's going to end!"? I can answer that: No. There is a reason why this is called 'fanfiction' you know. The fans make up the fiction. There are stories out there with horrible grammar and way bigger mistakes. Why my story? I'm sorry if this offends you, but if you decide not to read this anymore, I won't cry at the loss of one reader.

This is my story. I make up the rules. If I say something happened in my story, then it happened! Sorry, but that's the way it goes.

Anyway, now that I'm done being bitchy, on with the story…

************************Interlude: Dreams of the Insane****************************

'You found hope, you found faith

Found how fast she can take it away.

Found true love, lost your heart,

Now you don't know who you are.'

-Jessica Riddle "Even Angels Fall"

'Pretty forest,' Buffy thought to herself. 'Creepy, but pretty. Where am I?' She asked herself. "Hello? Is anybody out there? Hello?"

"Hello?"

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

"Ok, you're asleep. You're also wide awake in the middle of the forest. You must be dreaming. Yeah, that's it. I'm dreaming. Now I'm talking to myself. Oh, well. No one around to hear. So, where am I?"

"Hello? Is anybody out there? Hello?" Someone yelled.

"Hello?" Sirius yelled back.

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

"Ooh. Someone's here with me. Wonder who it is. And what in the world am I wearing? It's pretty, but I don't remember going to sleep in a dress."

She was wearing a spaghetti strap, cream dress that flowed to her ankles. It was tight on the bodice, but wavy on the skirt. Oh well, it was a dream. Anything can happen.

"Hello?" She yelled back.

"Over here!" The voice sounded strangely familiar.

Buffy walked toward the sound of the persons voice. When she got to him, she stopped short in surprise. "Sirius?"

"Miss Summers?"

Sirius was beyond confused. Here her was, in a… forest that he had never seen before, standing by Buffy Summers, who was wearing a dress and looking very beautiful. And she was staring at him oddly. No, she wasn't staring at him. Not exactly. She was staring at his clothes. Sirius looked down and groaned. He was wearing a tux. Why?

Buffy knew she was staring. And she didn't care. Man, was this guy yummy in a tux or not? Buffy looked up when her groaned and smirked. "Hey, do you think I like this choice of wardrobe?" She asked, glaring at the offending dress.

'No, but I like it on you,' he wanted to say, but kept his mouth shut.

Suddenly, everything went dark, and they weren't in the same place anymore. It grew fuzzy and cold. 'Oh no,' Buffy thought. 'Not the dream, please not the dream.' She backed away and slammed into someone. Yelping, she jumped back, tripping over something on the ground and landing on her back.

Sirius grunted after someone ran into him. Where was he? And where was Miss Summers?

Someone nearby yelped, and he realized it was her. "Miss Summers? Where are you?" He called.

"Down here," he heard. He got to his knees and felt around until he and Miss Summers bumped their heads together.

"Ow!" She moaned. "Are you okay?"

"Yes. What about you?"

"Peachy with a side of keen. I tripped over something, and me'sa thinking it's a body. But, hey! I'm not wearing a dress anymore!"

"Me neither. I mean… I'm not wearing a tux." He corrected himself quickly. He heard her sigh as something brushed against his leg. He rolled away and gasped. "What was that?"

"What was what?" She asked.

"Something touched my leg." He replied.

"Oh." Buffy decided that she wouldn't mention all the other bodies. Some were still alive. 'At least the screams haven't-' she was thinking before she got cut off by a terrified scream.

Sirius gasped. "What was that?" He yelled.

"Just the beginning," Buffy quietly replied. She heard him stand up.

"We have to go help."

"We can't. We'll never make it in time. I never do. You can run as fast as you can and you'll never make it in time. Watch." They waited a few seconds, then there was a bright flash of green light and they weren't there anymore.

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

Sirius felt a draft and he looked around. They were back at Hogwarts, in the Great Hall. He looked at Miss Summers and his eyes went wide. She was wearing boxers with some kind of animal on them, and they said 'SpongeBob SquarePants' on them. Whatever that meant. Her tank top matched. Why was she wearing that?

Buffy felt Sirius' eyes on her, so she looked at herself and moaned pitifully. She was wearing her pajamas! Oh god. She looked at Sirius and almost laughed out loud. At least she was wearing a shirt! All Sirius was wearing was black boxers.

Sirius heard Miss Summers stifle a laugh, and with a sinking feeling, he looked down at his own clothes. Or lack there of. Oh, god. Why, oh why, did he have to wear his boxers that night?

"Umm…" was all he said.

"Well, I guess we're really back at the castle and not dreaming anymore. We probably sleepwalked here." Miss Summers told him.

"Umm… Well, we'll talk about this in the morning. Right now, I'm going to go to bed. Good night." Sirius hastily replied, flushing as he quickly backed away.

Buffy smiled after him as he practically ran to his room. He looked so adorable when he blushed! Buffy looked around warily. Which way to her room? She sighed. It was gonna be a long night.
