Author's Note : For the purpose of this fic Angel and Spike do love each other (In a violent love hate kinda way). Not very much romantically but in a familyish way, but with some bits of romance. What can I say, they come from a fucked up family.

Chapter 9. Nobody switches like switches do switch.

Voldomort looked at his most treasured and beautiful minion.

"It issss doneee?"

"Yes My Lord. We may proceed with their reward."

Voldomort's face twisted into what must be a smirk.

"Eeeexsssselent"

Spike looked down at his sleeping sire and sighed. He knew Angel had not wanted to make a deal with the stuffy wizard types, but had done so for him, and while any would think he had done it for himself too, they really didn't know Angel. Not like he did.

Because of his stupid need to become corporeal he had probably ruined some kids life. How was he supposed to live with that? Well he supposed he had lived with a lot more, trying to rape Buffy for one, but in those incidents he could comfort himself with the fact that he didn't have a soul. After being with Angel and Angelus for so long he could understand the difference, but he had hurt someone with a soul. Did that just mean he was a bad person soul or not?

He sighed again and slipped into bed with his sire, the little comfort he had. Angel would probably kick his translucent ass in the morning but for tonight everything was fine. Spike drifted off to sleep with the knowledge that his sire was close by, protecting him. He smiled; all he had ever wanted was Angelus or Angel's acceptance.

Buffy stood in front of he class of first years. Gryffindor and Slytherin, it seemed that history was doomed to repeat itself. One boy spat a spit-wad at another. Buffy sighed. She had a lot of work to do if she wanted to stop this destructive inter-house rivalry.

She swayed slightly, a dizzy feeling suddenly coming over her. Black spots appeared in front of her eyes. And then she felt a tearing. Something was tearing at her soul, pulling it from her body. Buffy did the only thing she could do, she screamed.

The class watched, rivalry over, as their teacher screamed and dropped to the ground.

For a few seconds it was pure panic. A few of the girls were screaming, terrified that the invisible monster would come after them. Others bustled around Buffy to see what had happened.

A slythering by the name of Toby finally stepped up as leader.

"Everyone step back," he shouted, "she needs some air!"

Desperate for someone to take over control they all obeyed.

"And you, all shut up!"

He motioned towards the girls huddled in the corner, whimpering crying and generally screaming their throats raw.

"Now you," He pointed to a calm looking Gryffindor, "Go get McGonagall."

The boys quickly exited.

Toby pointed to a fellow Slytherin.

"Snape," was all he said before the boy scampered from the room towards the dungeons.

"Does anyone know where the Headmaster'ss office is?" he questioned the remaining students.

A Gryffindor and Slytherin both tentatively raised their hands.

"Good, go," he ordered.

He looked towards a Gryffindor girl.

She smiled at him, "Madame Pomfrey right?" she asked.

He merely nodded.

After everyone had left to find their allocated professor or nurse, Toby went over to the form of their Professor. Her body was shaking, almost like she was having an epileptic fit.

"Someone get me a jacket," he ordered.

A soft cashmere jumper was quickly pressed into him hands. He pushed it under the Professors convulsing head, before pushing down on her shoulders, trying to stop her fit before she hurt herself.

Harry moaned silently in dread. Snape had been giving him looks, well not looks, smiles. Evil smiles that tell you that someone is going to get you BAD. He shuddered, before looking next to him. Draco was pretending like nothing had happened, last night with Buffy or in bed with him. A pleasurable feeling worked its way up his spine as he thought of 'The Kiss.' It had been fantastic. He had been kissed by a lot of people before, both male and female, but it had never felt like last night. He felt like he had been drowning in pleasure from a simple touch of their lips, but now Draco was ignoring that the best sexual experience of Harry's entire life had ever happened, treating Harry with cool indifference.

He had heard somewhere that the opposite of love is not hate but indifference. He shuddered at the thought. He may not have wanted Draco to love him but he thought he deserved more than a feeling of indifference. He had preferred it when Draco had hated him; after all, there's a thin line between love and hate. But now it just felt like Draco didn't care either way.

He was interrupted from his musing by a scared looking first year fumbling at full speed into the classroom. He almost knocked over a cauldron full of bubbling potion but managed to avoid it before he skidded to a halt in front of Snape's desk.

"Professor Summer... collapsed... screaming... help" was all the puffing boy managed before Snape hauled him out of the room on his was to the DADA classroom.

Draco and Harry merely looked at one another before following closely behind.

Snape was the first teacher on the scene. He quickly moved towards the still convulsing Buffy. He pressed a hand to her forehead, but felt no excess warmth, not poison then he thought, unless it was a highly advanced one, which was quite unlikely.

"Some one tell me exactly what happened," he commanded. The class remained silent.

"NOW!"

"Sorry, sir," Toby finally spoke up, "WE don't know what happened. She was telling us about vampires and how they are turned, and then she just went silent for a little while, " he shuddered, "And then she started screaming, and she just fell to the floor. She's been thrashing about ever since, thought it's less now than it was," he explained, relief clear in his voice.

"Has someone gone to get Madame Pomphrey?"

Toby nodded.

"And the Headmaster?"

Toby nodded again.

"Good. Now I think it's time for everyone to leave. A seven inch scroll on how vampires are turned is due next lesson, now off you go."

"But Professor," a small Gryffindor girls spoke, "What about Professor Summers? Will she be all right?"

"Of course she will be you silly girl. If someone had wanted her dead I think they would have done it by now, don't you?"

The girl whimpered at the thought of her Professor dead.

"I'm sure you'll see her at dinner. She never was one to pass up a chance to annoy me," the last sentence was muttered under his breath but from the giggles around the classroom, he was fairly sure some had heard him.

Dumbledore, McGonagall and Madame Pomfrey arrived shortly after the students had left.

Dumbledore looked at the damage around the room. Buffy laying on the floor, finally still, Snape leaning over her trying to discern what was wrong, Draco sitting in a dark corner with Harry at his side, withdrawn from the prospect of his second favourite professor being hurt or killed.

"Or dead," was all he could say.

He headed towards his new professor, just as she began to open her eyes. Dumbledore visibly sagged in relief.

"Buffy, my dear, are you quite all right? The students said you passed out."

All Buffy could do was shake her head.

"No, no, I'm not all right. Not by a long shot," he voice sounded odd, as if she was trying to make it deeper, but somehow her voice would not cooperate.

"What's wrong?"

Buffy's eyes met Dumbledore's and Dumbledore saw a familiar look, eyes that had seen too many years, an old soul. Buffy had always had that look, but it was so much deeper now, deeper than even his own eyes after his one hundred and forty-seven years. He was confused, how was that possible?

He was woken from his thoughts by the sound of her voice.

"Well for one I'm not Buffy. And two, what the hell is Buffy doing at Hogwarts?"
