Disclaimer: I don't own Buffy and Harry. Joss Wheaton and J.K. Rowling have the honor.

A/N: Hey peoples. Glad to hear that your all still liking this! Yay! Thanks everyone that reviewed me and welcome to the new readers! Here is the next update, sorry it's a little late, a whole day! Stupid Biology Exam! Oh and the URL was down last night so I couldn't have updated when I tried. Oh well: here it is.

Teaching is a Whole Different Language:

Harry pulled out his wand and commanded, "Lumos."

He pointed the wand onto the road. There was a screech and a large double decker bus appeared out of nowhere. Sirius was already in dog form.

Harry took charge as Buffy gestured for him to do so. "Hello," He greeted the bus driver. There is the two of us, and my dog. We were hoping to get to Diagon Alley."

"Not a problem young sir. Step aboard, that is our next stop."

The three got on and Buffy was shocked to see that the inside of the bus was huge. Much larger than it could possible be on the out side. Buffy jearked out of her awe when the conductor said to her, "That will be ten galleons and seven knuts." Buffy pulled out her pouch with the money Dumbledore had given her and looked in, before realizing she hadn't a clue what was what. Sure she knew the exchange rate but that was about all.

She looked at Harry franticly. He stepped forward and took the sac from her. He counted out the correct money and he watched amazed that he knew which was which.

"With this we get to have a bed each, it comes standard." Harry whispered and led her over to the beds by the back of the bus.

"Let me explain you the money and some other things." He told her taking charge. She listened fascinated as he explained the money and how it worked. Then he told her about Diagon Alley and what they would see there." Sirius sat on the bed and listened with pride in his eyes and his godson explained what he had only learnt a few years ago myself. Harry seemed to be enjoying himself.

The trip passed quickly and soon they were being let of out the front of an old rickety pub. "Are you sure that we are at the right place?" Buffy asked the two.

"Yes." Harry assured them. They entered the bar. Harry quickly talked to the bar man who seemed to know Harry and the boy got them two rooms. When he came back to Buffy he told her that Ron and the others had also booked their rooms for the next night.

"Okay then, I suggest that we put this trunk of yours into your room and then we can all get something sent up to out rooms to eat." Harry nodded and he led the way up the stairs. He opened his room and Buffy set the trunk at the end of the bed. "Right, where's my room?" She asked.

"Across the hall. Here's your key." She accepeted it and went to her room and threw her bag onto the bed. Then she re-joined Harry and the now human Sirius. "Okay, I'll go down and order lots of food." She said enthusiasticly and Harry laughed. She was pleased because it didn't seem as though Harry had had a lot of laughter in his life over the last few months.

They ate well and all enjoyed themselves, Harry talking about his holidays and Sirius also speaking of them. Buffy told them about where in America that she had come from and about her friends. She also explained to Harry they new class that Dumbledore had added to the course at Hogwarts and that she would be teaching.

"Not only do we have the best for Wandless Defence, but we also have the best teacher for defence against the dark arts." Sirius murmered.

"What do your mean? Who is it?" Harry asked.

"Why, your uncle Remus of course."

"How ever did they manage that?" Harry asked incredulous.

"Dumbledore put his foot down. Don't worry about him though. He had everything under control. I think that Dumbledore has a secret weapon up his sleave this year though incase anyone complains." Sirius explained, throwing Buffy a look that Harry didn't see that told her that she was it.

Buffy rolled her eyes at him and stood. "I'm going to bed. I'll see you both in the morning." She left. Taking the pills that Madame Pomfrey had given her; she curled up in bed and had a dreamless sleep. She woke to a loud bang on her door.

Grumbling she got up and opened it. The black dog was there pasing worriedly.

"What is it?" She stood back and let him in. Glancing at her watch she saw that it was two in the morning.

"Sorry, I didn't mean to wake you. Dumbledore said that you don't sleep untill early morning." Sirius explained.

"Yeah, well I have a few things to say about that and him if he keeps telling people that." Buffy muttered then looked down and realized that she was wearing cutesy pyjamas. Then putting a hand to her hair, she felt that it was really off. She moaned. "I have bed hair." Sirius couldn't help it. He laughed. "Well I'm up. What do you want?" She demanded coolly.

"Sorry again, but it's Harry. I am worried about him. He's been having nightmares and every time I wake him up, he insists that he is okay, then he goes back to sleep and has another nightmare."

"Let me guess, you were wondering whether I would go in and speak to him?"

"Well, maybe he will talk to you because you're a girl." She arched her eyebrow. "I mean that he knows me and might feel embarrassed about it."

"Sure. I'm up now anyway." Buffy grumbled. You stay here, and don't mess up my things." She muttered and grabbed the robe that was provided for her. Slipping on slippers, she trudged across the hall.

When she entered the boys room, she noticed immediately that the boy was dreaming again. She sat on the bed beside him and shook his shoulder gently.

"Voldemort!" He cried sitting up straight.

"Harry, calm down, it will be okay, don't you worry about that." She wrapped an arm around the boy. She expected him to pull away but he didn't. Shocking her, he started to sob. He told her the tragic tale of what had happened the year before, when he had been captured by Voldemort and Cedric Diggory had been killed. Harry finaly finished. He reminded her a lot of Dawn, them both being the same age, and she decided to do what she would do for her sister.

She rocked him. Softly she murmured to him until he fell asleep, then she lay him back down in the bed and covered him in warm clothes. She snuck out into her own room and saw that Sirius had fallen asleep in her chair. She sighed. Covering him with a blanket she went back into Harry's room and found a blanket in the closet. She also found a book that was a magical novel.

Buffy knew that she wouldn't be going back to sleep anytime soon so she flopped in the chair and read while watching over the troubled teen.

When Harry woke at dawn, he felt a strange sense of safety. He looked around the room and saw that the girl that he had met the day before was fast asleep in the chair beside his bed. He got up and dressed quickly. He looked up and saw that Sirius was creeping back into the room. Harry put his finger to his lips.

Sirius was confused so Harry gestured to the sleeping Buffy. Sirius nodded and they left the room and wandered down the stairs.

Tom the barman greeted them and they ordered something to eat. Choosing a table at the back of the room they sat down.

"Where did you go last night?" Harry asked.

"I fell asleep in Buffy's room."

"What were you doing there?" Harry demanded.

"She went to see you and I fell asleep while I waited for her to come back. She must of though, because there was a blanket over me when I woke."

"That would mean that she stayed all night in my room." Harry exclaimed.

"Yes, and probably awake too. Do you feel better this morning?"

"Yes thankyou."

"Did I miss the party?" A voice called from behind them.

"Morning Buffy." They choursed. She eyed them suspiciously but sat down anyway.

"So children, what would you like to do today?"

Sirius glared at her. "Harry needs to get his school things. We can show you around."

"Great." She rubbed her hands together. "When do we start?"

"Once we have eaten breakfast."

"Wow, you guys really eat breakfast? I never do that." They just stared at her incredulous. "What?"

"Breakfast is the most important meal of the day!" Harry exclaimed. At that moment the food was brought out. It looked like bacon, eggs, sausages, and hot tea. Buffy looked a little green.

"Tom?" She asked the man, "You don't have any coffee do you?"

"Sure do miss. I'll just get you some now shall I?"

"Thanks." The two were still staring at her. "Look, at home I was out half the night and up till all hours, then school straight away in the morning. I didn't have time for breakfast."

"How old are you?" Harry asked, then blushed as he realized that what he had asked was really rude.

"Harry, Buffy doesn't have to answer that if she doesn't want to."

"That's okay. I'm twenty one, twenty two this year." They both gaped at her.

"Your so young."

"You mean that I look older?" She demanded. Sirius didn't notice the warning tone in her voice.

"Well yeah." Sirius continued. Harry tried to catch his eye to tell him to shut up. He didn't notice. "I would have thought you were more twenty nine or thirty."

Buffy's eyes bulged and she shot a venom filled glare at him. "I am not OLD!" She growled through her teeth and stood up. She ignored them completely and moved to the bar. She paid for her coffee then asked Tom a direct question. "Are there any vampires with nests around here?"

"Well yes, but people like to keep clear of them."

"Can you tell me where they are?"

"Of course." The bar man gave her directions and she stalked out of the bar.
