A/N: Hey people! This is my first HP/BTVS crossover fic! So please be nice in your reviews! :-) Oh, and so you won't get confused, spoken lines in the fic use "CooL!" and thoughts are 'whatever', and emphasized words are *alright!*

Chapter One: Revenge is Sweet

Sunnydale, quite an ironic name for the town that was and still is famous for having the highest death rate in the whole of California. Only a few knew the truth behind the mysterious murders, and only a few knew on how close the world had come to ending...

Sunnydale

Willow Rosenberg awoke with a start, her heart thumping wildly in her chest. 'Just a nightmare.' She calmed herself and wiped the beads of sweat that trickled down her forehead.

But she knew that it was more than just another nightmare. It was the same nightmare that had been tormenting her every time she closed her eyes at night. What she had feared the most had come. The ghosts of her past had come back to haunt her.

Images of Tara's death swirled in her mind, and for a split second, she felt the familiar surge of power flow through her blood and veins.

Vengeance.

The one word that made her seconds from ending the world.

Guilt blanketed her back to sleep, but not after shedding a few tears of pain.

Warm sunlight streamed through the half-open window of the Slayer's bedroom, gently awakening her from her peaceful slumber. The blonde smiled serenely and stretched languidly on her bed. This was how she liked to get up in the morning, when all was quiet and tranquil.

Ring! Ring! Ring!

An annoyed frown creased her face. Who would want to call her at seven in the morning? She thought crossly after taking a quick glance at her wall clock.

"What?" she practically yelled into her mobile phone.

"Buffy?"

Great. It was Giles. He probably needed research or something. Not to take it the wrong way. She loved Giles like a father, but certainly not during mornings. It just got her cranky.

"May you meet me at the Magic Box in a few minutes? I need to discuss something with you..."

"Sorry Giles, but I've got work to--"

"It's about Willow." Gile's tired voice cut her off.

Buffy's eyes clouded over with a flutter of mixed emotions. "Fine," she said curtly, and switched off her cell.

It had almost been three days since—the Willow incident, and Buffy still didn't know what to think of it. The two of them had spoken of course, and Willow had apologized profusely about what she did.

But Buffy will never forget what her best friend had almost did to all of them, to Dawn, to Giles, to Xander, hell, even to Anya. And she will never forget the look on Willow's face.

The look that held uncontrolled anger. And for the first time in their lives, it had been directed at all of them.

And it hurt.

Los Angeles Prison

Faith Wilkins dropped down from the steel bar she was hanging from on the ceiling to the cold damp floor of her cell. Unlike the other prisoners in LA Jail, she was forbidden to see anyone at all, and with no one to talk to, she had resulted to working out 24/7.

She tossed her dark brown hair behind her shoulder before she plopped down tiredly on her bunk. Being the Slayer wasn't so fun after all, especially if you had nothing to slay.

It had almost been two years since her murder of the deputy mayor, and she only needed two more to be finally rid of this place. Pain and guilt creased her face. She had hurt so many during that time, and the remorse was not lost on her.

She ran a finger down the cement wall beside her which was covered in metal scrapes, she was counting the days till she would be free, counting the days until she will have to face the people she had hurt in the past.

Footsteps resonated from the corridor, distracting her from her thoughts. Following after came a series of knocks on her door.

A look of surprise crossed her face. She rarely got visitors, and those were usually the guards to bring her some food, and lunchtime was just over an hour ago.

The door swung open to reveal security, and a middle-aged man that she had never seen before in her life. "Faith Wilkins?" he asked, motioning for her to come forward.

Faith nodded her confirmation and did as she was told to do. "What do you want?"

"Your presence at Sunnydale, California."

His answer shocked her, but nevertheless, she kept silent. She wasn't about to ruin her chances to be released from prison.

"Some people have requested to see you—personally."

With her heart thudding in her chest, she followed the man out.

Sunnydale

"Bye Dawn!" Buffy yelled from the passenger's seat of Xander's car. "Take care! And remember to call me if something happens!"

"For the hundredth time, okay!" Dawn shouted back, rolling her eyes as she made her way through the open doors of her first day in high-school life.

Xander grinned at her before driving off. "Do you think that there still might be some weird stuff going on there?"

"You'll never know with Sunnydale High," she responded with a shrug. "We are, after all, on top of the Hellmouth."

"Good point," Xander mused, as he parked along the sidewalk of the Magic Box. "I'll see you later Buffster," he said with a warm smile as Buffy climbed out, the feeling of regret already in her mind.

The smell of magic greeted her the second she entered the magic shop. Buffy glanced around in awe. The place looked great considering the state it was in three days ago. Giles was, as usual, seated behind the circular coffee table, his usual books about demons and Watcher stuff spread across it. "Good morning Buffy," he addressed. "Come have a seat."

She breathed in deeply before taking his offer. "So what's up?"

Giles looked tired, which wasn't so surprising, deeming the fact that he had been through a pretty rough time from spending a few months in London and having been welcomed back in Sunnydale by a witch who wanted to kill all who crossed her path.

"Willow has been doing well, don't you think?"

Buff's mouth tightened. Sure, Willow was starting to become the Willow they used to know before. But as Buffy had observed, every time the young Wicca would lay her eyes on a magic thing, it would cloud up with a blackness that could only be described as passing evil.

"Yeah, sure."

His eyebrows rose. "Why do I have a feeling that you're not all that comfortable with Willow yet?"

The petite blonde lowered her eyes to the floor. "Giles, she almost killed all of us. Of course I wouldn't be comfortable with her yet."

"But she is your best friend," her father figure persisted gently. She didn't know why Giles was being so insistent on getting her to be buddy- buddy with Willow again, but she knew that she was going to find out soon. Giles wasn't one to keep secrets for so long.

"Best friends don't kill each other," came the blunt answer.

Her Watcher sighed heavily before revealing a formal looking envelope from the inner pockets of his coat. "Quite right, but the strength of the power that she consumed was too intense for her, thus taking complete control over her."

Buffy eyed the creamy-colored envelope warily. "I know, but it still hurt Giles." She said softly, feeling something constrict in her chest. She didn't know why she had so much difficulty in saying that. Maybe because it was a sign of weakness. She was after all, the Slayer. And slayers were figures of strength and power. They *never* get hurt.

Understanding dawned on Giles' weary face as he nodded. "But I have one question for you Buffy."

"What?"

"Are you still willing to be there for your best friend?"

Hazel eyes met blue. And with all the confidence she could muster, she replied. "Yes."

"Good." Giles said, a smiling gracing his features, erasing the fatigue on his appearance. "I am sending Willow off to London to control her magic. And you will be going with her."

Faith boarded the plane with the flight to Sunnydale, California. Seating herself next to the window, she gazed off into the cerulean sky thinking about the town where she left her dark past behind and wondering why she was being sent back there.

She had of course, heard about Willow's killing spree, and Faith knew how the girl must've felt. After all, she too had been given the unfortunate chance of murder. It seemed only like yesterday that she had killed the Deputy Mayor, and she winced slightly as the horrific scene replayed slowly in her mind.

The plane was now taking off, and it wasn't long till they were soaring across the skies along with a flock of birds that were staring strangely at them.

As the minutes flew, Faith contemplated on the things she did two years ago, and what the Scooby Gang probably thought of her now. She hoped that they had forgiven her because believe it or not. Her two years spent in prison had made her regret every single thing that she did in the past, and now, she was a new Faith.

Yet she couldn't hold back the strangled sigh that escaped her lips as the dreaded town came into view. And when the plane landed, she took a deep breath and slung her backpack across her shoulder.

Ignoring the somersaults her stomach was doing, she made her way through the crowd and to a black car that was obviously waiting for her.

A man dressed in a black suit greeted her the second she came into earshot. "Good morning Ms. Wilkins." He spoke with a neutral smile.

Faith guessed that this must be one of the members of the Watcher's Council. And judging by the inhospitable look on his face, he didn't like what she did two years ago. "Good morning to you too, whoever you are," she murmured under her breath.

"Well then, I suppose your ready to head off to the Magic Box?" he asked, not bothering in introducing himself. He didn't seem to care much about her answer, because he ushered her into the car before she could reply.

"Welcome back to Sunnyhell Faith," she muttered lowly to herself before they sped off into the direction of the Magic Box.

The Magic Box

Shock registered on Buffy's face the moment the words had come out of Giles mouth. "LONDON?" she screeched. "That's like, a thousand miles from here! Who'll take care of Dawn? And more or less, who'll take care of Sunnydale?" She was slightly rambling now, but she pretty much didn't care. Helping out Willow was okay for her, because she too wanted the old Willow back. But leaving Dawn? And Sunnydale? Not exactly what she planned on doing.

Giles simply smiled. "Buffy, don't worry. I'll take good care of Dawn, and I have arranged for Faith to be here to guard Sunnydale while your gone."

Again, shock. "Faith?" Buffy echoed, a frown creasing her features. "Are you kidding me? She killed someone Giles. She's not welcome here anymore." She crossed her arms over her chest just to make her point.

"Willow killed someone too Buffy," Giles said quietly.

Buffy remained silent for a while before repeating what Giles had told her earlier. "But like you said before, it wasn't Willow's fault, the magic was too strong for her, it was almost controlling her."

"Then why haven't you forgiven her yet?"

It was amazing how one single phrase could affect a person. Her emotions once again collided with each other, jumbling each other in a tight knot that was almost impossible to untie. "Forgiving and forgetting isn't so easy Giles," she said softly. "But I will forgive Willow. Because I know that she will change."

"So then you believe that people change?"

"Of course," Buffy said feeling much of her confidence flow back to her.

"Then why do you not believe that Faith can change for the better?" Giles asked, raising his eyebrows in a way that made him look wise and old. No scratch that, he already is old.

"Fine," Buffy grudgingly admitted. "Maybe she has changed, but I'll believe it when I see it."

"Good," Giles said with a smile of approval.

"So, where's this place in London that you're sending Willow to control her magic?" Buffy asked curiously. The envelope was still firmly clasped in between his fingers.

"Hogwarts, a school for Witchcraft and Wizardry," Giles said with that secretive smile of his. "I used to go there when I was young. It taught me a lot about magic."

"Okay," Buffy said, still unsure on what this whole place held. "And why would you want Willow to be taught more spells that could possibly be harmful to our health?"

"You see Buffy, this school teaches magic that requires a wand. So when Willow performs spells, she will be exerting the magical power into the wand, making it a whole lot safer for both of you."

"Both of us?" she squeaked. "How do you know that I'm capable of such thing?"

"A Slayer is a creature of magic, and in your blood runs a magic that is more powerful than any other witch or wizard. You are after all, the Chosen One." Giles explained and took off his glasses to clean them. A habit that can never be taken away from him.

"So what's in the envelope?"

"This is for Willow," he said just as the entrance doors to the Magic Box swung open. A smile spread across his face. Buffy turned around expecting Willow to be standing there, but to no avail.

It was Faith.
