Teaching is a Whole Different Language:

She found the nest, they were sleeping off their dinner.

"Hello boys. Time to party." She called and slammed open the blinds. Sunliht streamed into the room and took out half a dozen on its own. Still there were eight left. Buffy surveyed the nest. They were fat. Obviously they hadn't worried about being hunted and hadn't kept in shape.

"Great, dessert." The fattest said stepping forward.

"Yeah, in your dreams." She threw the stake that she was holding and it dusted him in seconds. Another two rushed her and she planted a foot in one of their chests sending him crashing back and staked the other.

"Who are you?" A tall blond asked.

"Ever hear of the slayer?"

"Everyone has. She's in America though."

"Not any more." With that Buffy flew into a set of complex moves and kicks, knocking all unconscious. Then she routinely staked them all. She dusted her hands and looked in her watch. It was ten 'o' clock. She turned and headed back to the leaky cauldron.

"Hey Tom, where's Harry?" She called to the bar man.

"Upstairs in his room miss. His horde of friends just arrived."

"Thanks." She climbed the stairs and went to open her room. She realized that Sirius still had her key. "Damn!" She swore and went to Harry's room. She knocked at the door.

"Buffy! Your back!" Harry exclaimed pulling her into the room.

"I couldn't stay away for ever, could I? Besides, I had some things that I needed to take care of and I knew that however arrogant, Snuffles would take care of you."

Harry rolled his eyes. "Meet my friends." Buffy looked around the room that she noticed was awfully crowded now that there were so many people in there.

She was introduced to Hermione, Ron, Fred, George (who she could tell apart straight away), Ginny (Who Harry seemed to be particularly nervous around), Mr Weasley and Mrs Weasley. Buffy greeted them all warmly. She then looked at Sirius. "Shouldn't you be in you dog form, sir?" She asked him coldly.

"It's okay Buffy. They all know about Sirius." Harry offered.

"Very well. It really is nice to meet you but don't you think that it is a little crowded in here? Why don't we head down to this Ally of yours. I'm yet to see if it exists."

"You've never been there dear?" Mrs. Weasley asked her concerned.

"Not once."

"Well, we shall have to show you around."

"Guess what? Buffy is going to be a professor at school. She's taking the new class, Wandless defense class."

"Really. But you are so young!" Mrs. Weasley exclaimed concerned. Buffy smiled warmly at her and looked over at Sirius.

"See?" She said to him smugly. Sirius rolled his eyes. She turned back to Mrs Weasley. "I'm Twenty One. But trust me, I'm more than qualified for this job."

"Very well dear. You seem like someone that I can trust to teach my children." She placed an arm around Buffy's waist and walked with her out the door. The other's followed exchanging knowing looks.

"Where are we going?" Buffy asked as they entered the back room of the bar.

"This is the entrance to the Alley." Hermione explained.

Buffy studied the brick wall and looked at the others disbelievingly. "Here, I'll show you." Mr. Weasley stepped forward. He tapped the bricks in a specific order and the wall seemed to part. It became a perfect arch doorway that led to a cobblestone ally. Buffy was speechless.

"C'mon!" Ron called to Harry and Hermione. They hurried after him. Buffy hesitated. She didn't know this place and she was supposed to look after Harry. It seemed that Harry noticed her hesitation.

"Buffy, don't worry. I'm going to go to Gringotts and get my books then we all meet at the ice-cream shop for lunch. After lunch we all go together and get our stuff."

"It will be okay, Buffy. You can come with us." Mrs. Weasley told her.

"Okay then."

Buffy couldn't start to take in all the things that were shown to her. She went on the ride through Gringotts bank and loved every minute of it. Then she was able to exchange some of he money to wizard money and able to buy ice-cream with the others. Mr. And Mrs. Weasley insisted that she call them Arthur and Molly, and Arthur had been asking her all about muggle life styles.

She had been able to describe the telephone and the way to use it properly, without yelling. She had also told him about many other things, muggle post, televisions and as willow had explained to Dumbledore, can openers.

She had informed the kids that they better not continue calling her Buffy during class and they laughed and told her not to worry. The only thing that Buffy was concerned about was the twins scilence.

"I was told that you two were the life of the party." She commented when she was alone with them. They others had gone to get more ice-cream. "So, why are you so quiet?"

"Who us?" Fred asked.

"Never!" George protested.

Buffy laughed. "Then why haven't I heard a full sentence from either of you since we met?"

"Well."

"We weren't sure it was a good idea to get the new teacher mad before wed even returned to school. We might be into taking risks but were not that mad."

"Yeah, we can tell that you have strength and I like my arms where they are."

Buffy looked at the two stunned then broke out into helpless giggling. "You think that you get into trouble?" She asked them.

"Well, we do!"

"Hey, you haven't been in trouble like me. You should have seen my friends and myself in high school. Your punishments are nothing!"

They gaped at her. "How could you possibly have received that much punishment?"

"You must have done something really, really bad!"

Her eye's twinkled. "Well, after my first school, my record wasn't really the best." She told them in a low voice leaning forward. They leant forward too, keen to hear this secret.

"The principle wasn't too pleased with me so he took every opportunity to give me detention, so I took every opportunity to keep out of his way. I spent most of my time in the library."

"What did you do to get such a bad record?"

"You have to promice not to tell everyone. I don't think that even Dumbledore would have taken me on if he knew." She whispered. She knew for a fact that Dumbledore knew her past, it was part of who she was.

"We promice!" They said simultaneously.

"Okay then, I burned down the school."

"WHAT?" They exclaimed.

"SHHH!" She hushed them. "You want to know what else?"

"Yeah!"

"I blew up the next school too. It was at graduation and we wanted to go out with a bang, so to say. Of course there was a good reason both times but that isn't something that I can tell you about." She was sure that she had gotten through to them. She suddenly thought of something. "This isn't a suggestion though. Some how I don't think Dumbledore would be too impressed if you did that to Hogwarts. The school seem older than most of the people I have ever met altogether." She stoped realising she was babbling.

The twins sat back, clearly in aw of her, but much more relaxed. When the other's returned they noticed the changed atmosphere.

"What have you done to Buffy?" Molly demanded, turning on the twins.

"I'm afraid Molly, that it was I that have stunned them." She looked at Buffy shocked.

"Well what ever you've done, you've earned their respect."

They nodded in agreement with their mother. Buffy only shrugged.
