The Teaching Is A Whole Different Language.

It was late at night but Buffy couldn't sleep. She got up and poured herself a glass of water. She missed Dawn. Their wayward father had shown up and after a long heated discussion with Buffy, he had taken Dawn to go and live with him.

Buffy had been distraught. Dawn sent her letters weekly and that helped Buffy to deal with things. She had kept a lot to her self over the last month and it was getting toward the end of the summer holidays. She knew that she would be worrying that her good for nothing father was able to get Dawn into a school. She knew he would have but that didn't stop her worrying.

She dressed and left the house locking it behind her. Something that she had never had t worry about before because Dawn was always there waiting for her to return from her patrol. It was one of those nights and there was no action.

Her thoughts wandered. Giles had flown back a week ago, finally receiving her message that her custody of Dawn had been taken away. He was better off since she had last seen him. He had left Buffy to learn how to deal with things on her own. She was so far doing a good job.

She had a good job at a local clothes store and was bringing in a fairly good income, not a lot though. It was enough to cover the bills and to buy her food. She had been dealing with Dawn too. She had turned over a new leaf. Buffy finally decided to take her out on patrol and Dawn had loved it. Gone were the sisters dark colors and in came the whites and bright colors.

Since Dawn had left however, Buffy had slipped back into old habits.

Buffy sighed and found her self walking towards Giles' apartment. She knocked on the door.

"Hello Buffy." Giles said, opening the door for her to enter.

"Your still up?" She inquired.

"Yes. So are you it seems." He raised his eyebrows at her cloths. Since Giles had returned she had tried to make an effort but tonight she couldn't be bothered. She was wearing black, Maroon blouse, Black pants with a black miniskirt over the top. She wore a black choker and black lipstick. She was an image of night time.

Buffy entered his apartment and noticed that there was a man sitting on the couch. "I'm sorry Giles, I didn't realise that you had company." Buffy murmured, smiling politely at the man. He appeared to be in his eighties with a long white beard and glasses that sat on the end of his nose.

"Actually Buffy, he's here to see you. I was going to bring him around to see you in the morning but seeing you're here."

The man stood. "Buffy Summers?"

"Yes? Are you from the watchers council?" She demanded eyeing the man suspiciously. He laughed a deep pleasant laugh.

"I can assure you that I am not from the fabled Watchers Council, Miss. Summers."

"Buffy, allow me to introduce an old friend of mine. This is Albus Dumbledore, the headmaster at Hogwarts School of Witchcraft and Wizardry."

"Pleasure to meet you." Dumbledore put in.

"And you sir. It's always good to meet Giles' friends. Up until recently, I didn't realise he had any." She grinned wildly to show that she was joking. Giles just rolled his eyes.

"Buffy, I was wondering if I would be able to ask of you what I have came here for." Albus asked.

"Of course." She plonked herself down on the couch opposite the man. Giles sat too.

"As Rupert has just said, I am the head master of a school for witches and wizards and am in fact, a wizard myself. My problem is that I have several students at my school that seem to continually get them selves into trouble. They are caught in situations that attract the dark wizards. This year, I have decided that it would be beneficial to hold a class of wand less self defence class. I am also sure that you would be a great advantage to one of our professors in the class Defence Against the Dark Arts due to all the on field experience you have had. I came to the best for help."

Buffy was shocked. "Where is your school?"

"It is in England."

"You do realise that I have duties here at the Hell Mouth. There is the big bad and all that surfacing regularly."

"Buffy." Giles interrupted gently. "I have already taken care of that. I have been in contact with the Council and they have told me that the demon activity in Sunnydale has died down considerably and relocated to L.A."

"Angel." Buffy whispered in shock.

"Stop worrying Buffy. I have been assured, by Wesley himself, that they have the situation under control."

"Very well. What about the regular Vamps?"

"The gang here is more than capable of dealing with them. They handled the problem quite well while you were, umm, out of action last summer." Giles told her. This also let her know that Dumbledore didn't know that she had died. I suppose that is good she thought to her self.

"Well, I don't have to worry about Dawn any more." Buffy sighed, her heart wrenched. She looked at the headmaster. "When do you want me to start?"

"I return to the castle tomorrow afternoon. If you come with me I can save you the worry of airfares."

Buffy was puzzled but her ears had pricked up. "Castle?" She demanded.

Both men laughed and Buffy remained confused but neither offered an explanation. "Well then, I guess that I will be leaving with you then."

The headmaster beamed.

"Giles.umm.would you be coming with me by any chance?" She asked hesitantly. She was still not sure if her watcher was going to up and leave her again and it would take a lot of work to get their relationship up and running smoothly again.

"Of course." Giles wouldn't imagine dumping his slayer in a place that she wasn't familiar with.

"Great. So I'll write to Dawn in the morning and let her know where I am." She looked up concerned. "Will Dawn be able to contact me?"

"Of course Buffy. We will write to her from Hogwarts to see of she is okay and to show her how to contact you." Albus reassured her.

"Good. Thankyou sir." She went back to musing. "I'll have to speak to the gang also. Let them know that they are on their own for a while."

"Buffy, there are a few things that I will need to tell you before you come with me to Hogwarts."


"Well, the witches and wizards there aren't all that aware of the smuggle world."


"Non wizard people."


"Yes, well, most are from wearing families and they weren't brought up with cars, telephones of the postal service. Just about everything that you take for granted, they will have grown up without." They continued to talk through out the night. Giles got some sleep but Buffy didn't need to part because of her Slayer abilities and part because she wasn't tired.

Professor Dumbledore told her that she would be known as Professor Summers while at Hogwarts and then told her about all the other professors. He told her about some of the more influential students and the like, including Harry Potter, Hermione Granger, the whole Weasley tribe, the Malfoys and a few others. He explained the housing system and other school rules. He then told her that she would be paid well. He explained wizard money and the exchange rate and all of that. Overall the teachers in this college were paid more than the teachers in America.

"Alight," Buffy said once everything had been explained to her. "From what you have told me, there are no problems with the education of the students and you mentioned a dark wizard. You want to tell me about him of am I going to keep guessing?"

Dumbledore sighed. Then he told her all about the wizard named Voldemort, once known as Tom Riddle. The tale was a messy one, with the bad guy re surfacing regularly to cause trouble for this Harry Potter.

"I'll just take a stab in the dark and say that you hope that I'll be able to do something about this problem then." She said, looking him in the eyes. He looked back and she knew that she had guessed right. "Okay, piece of cake."

He looked shocked and she smiled sweetly. "From what you've told me, to kill someone with one of these curses of yours you have to hit them with it."

"Yes." He agreed.

"Well that wont be any good on me then will it?"


"He wont hit me. I'm too fast."

He looked at her peculiarly.

"I don't lie and I don't gloat. I'm just stating the truth."

Dumbledore said nothing but seemed accept that with the thought that he'd believe it when he saw it.

"One last thing." She added.

"What would that be?"

"No one knows that I am the slayer accept maybe the teachers. That would be too dangerous for both them and me. The other thing is that I will not take any crap from anyone. Teachers or students."

"I'm sure that once you have shown them you mean business then they will not bother you."

"Good. You have your self a teacher then sir."

She held out her hand and they shook on it. "Get some sleep sir, I'll see you at the Magic Box tomorrow, Giles will take you there. I'm going to patrol."

With that she left the room.

There was a science when she had gone. "Is she always like that?" Dumbledore asked the now awake watcher who was standing at the entrance to the kitchen.

"Yes, always."

"She doesn't look well though, Rupert I can see in your face that you are worried about her."

"Yes. I only returned from England recently and I am beginning to regret ever going. It appears that things have fallen apart since I have been gone. Buffy has been under a lot of stress after the custody of her sister was taken away from her."

Dumbledore nodded. "I can't imagine how she's dealing with that."

"Neither can I. She and Dawn were always very close. I don't think that she is eating properly or sleeping."

"At Hogwarts, Madame Pomfrey is a very capable healer. I'll get her to subtly take a look at the girl when we get there. If there is anything wrong with her then she'll see it." Giles sighed. "What? There's something else that you aren't telling me."

"Yes. About a year ago Buffy died." He could see the shock in Dumbledore's face at this news.

"How is she alive now?"

"When I returned to England her friends decided to play with black magic and brought her back to life. I don't know the details of the spell that they used, but I do know that they were attacked by demons and didn't remember to dig her up out of her coffin first. They just assumed that the spell didn't work. She had to claw he way out and has never really been the same since. Also, we had all assumed that she had been in a hell dimension but she was actually in heaven."

"Good gracious."

"There was no pain, no fear or doubt, 'till they pulled me out, of heaven." Giles muttered.

"What was that?"

"They were Buffy's words. We had an issue with a musical demon named

'Sweet'. That was when we all found out where she had been. I'm worried though. I think that she might be depressed or something. I had thought that she had overcome her need to wear black."

"Give her time Rupert."

"Yeah, I suppose that would probably be the best thing to do. Now 'professor' I'll show you to the spare room so that you can have at least a small amount of sleep no matter how much you protest that you are not tired. Believe me that you need strength to deal with Buffy's friends.
