"What if you were possessed?" Rose asked

The quartet were in the Great Hall, eating breakfast. Scorpius and Albus had quickly filled the girls in on the events of the night before

"Don't be stupid, how would we know?" Becky asked a touch scornfully

Albus was suddenly quiet his face thoughtful.

"Mum would know."

"Your mum? What are you talking about?"

"She was possessed."

There was a moment of silence, until it was broken by Scorpius choking on his toast.

"Your mum was possessed?" he and Becky said in unison, both incredulous.

"In her first year. I don't know much about it, but I think if you're possessed you can't remember anything." Albus turned to Scorpius. "Can you remember anything?"

"I think...singing?"

Becky looked triumphant. "See? I told you it couldn't be possession. And your family is messed up." this last comment was directed to Albus.

"It was just a possibility!" Rose said, stung "And I don't know when you became an expert in possession anyway, Rebecca!"

"Don't call me Rebecca! And I-"

Their discussion, which was rapidly becoming heated, was interrupted by a paper bird, that flew between Rose and Becky and hit Scorpius in the head. Ignoring the snickers of his friends with affected dignity, he fished the bird out of his thankfully empty goblet.

To Mouse et al. - Stop arguing it read in Minna's quasi-neat handwriting at least, we presume that's what you're doing. If you want some ideas, Nat this was hastily scribbled out Professor Carter has a few. Go to the DADA office- we'll meet you there. Prof G

They glanced up at the Staff table, where Minna gave them a wave, then returned to glowering at Professor Hendricks.

A group of startled fourth year Ravenclaws gave Scorpius, Albus, Becky and Rose evil glares after they burst out into laughter as they left the Great Hall.

"Why does she hate Hendricks so much?" Albus asked, as they climbed the stairs.

"Why don't you ask our resident Greyter expert?" Becky asked, finally have got over her fit of giggles. Scorpius raised his eyebrows at her, although the effect was rather spoilt by his jumping of a trick step.

"Greyter?!"

"Why not? Loads of celebs have thingy words – where they're all mushed together, like Brangelina." Becky retorted

"Portmanteau?" Rose suggested

Becky flashed a grin, "Exactly – portmanteau."

Scorpius realised that his friends gazes were suddenly upon him...he pulled a face whilst he thought about it – he knew that Minna had known Hendricks before she had started to teach here, but he couldn't remember exactly why or when their emnimity had come about.

"I don't really know," he told them "Weirdly though Min's best friend out of school is Hendricks' sister – Marina Gamp. I think it was something to do with the pureblood social season, Minna saying something daft and with a lot of booze, it didn't go down to well with Mr Hendricks..."

His friends nodded, but as they turned the corner to outside Nat's office, Scorpius had to hide his laugh at Al's horrified face- the words 'Mr Hendricks finally having sunk in.

"Mr Hendricks!?" Albus finally choked out. "As in, she's married?"

"I think so. Anyway, I don't really know why – I think it's just that they're too stubborn to admit either of the were wrong."

Rose gave Scorpius a thoughtful look as they entered Nat's office. Having only seen it when he was invited there at the beginning of the term, and Mouse had been rather preoccupied with the fact that his cousin, who had disappeared over a year ago was, a) now blind and b) his Defence against the Dark Arts Teacher for the foreseeable future, he hadn't really thought to look at his surroundings. So, whilst waiting for Nat and Minna to arrive, Scorpius and his friends looked around Professor Carters 'domain'.

Diagrams of Dark creatures, and maps, their edges slightly raised lay scattered around the room, either pinned to the walls or lying on a small side table. A strange looking machine, like a typewriter, but with fewer keys lay on on the desk. Scorpius, slightly curious reached out to touch it...

"I wouldn't do that if I were you."

Mouse whirled around guiltily, directing a sheepish grin at his cousin and his fiancé.

"Did he have his grubby paws on my brailler?" Nat said, half-jokingly

"Hey!" Mouse protested, and his friends laughed.. Nat, using his light spell, made his way to his chair, Minna perching on the edge of the desk. Unable to hold in his curiosity any longer, Mouse burst out.

"What was that? Last night I mean."

Nat's face was drawn, a thoughtful expression on his face. Albus fidgeted nervously, whilst Becky Rose and Mouse looked to him expectantly. Eventually, Nat spoke.

"Min, grab me that book on the history of Dark Sorcerers, would you?"

"Which one..." Minna muttered, drawing laughter from Mouse and Albus.

"I heard that. The big one...I think it's red."

"You mean this one?" Minna said, innocently, holding up a book. Nat took it from her, his long fingers dancing over the Braille title.

"That's the one."

Mouse stifled a snicker.

"It's green." Minna said, again in a tone of voice that suggested butter would possibly freeze in her mouth. She dodged a playful and surprisingly accurate swat from her fiancé.

"That's not very professional" Minna said, teasingly.

"Shut up would you? It's hard enough to read this without you distracting me."

"I'm sticking my tongue out at you." Minna announced, whilst Rose, Becky and Albus looked on bemused. After all, Mouse reflected, it must slightly surreal to see your teachers openly flirt with each other – or even show signs of being people, rather than a teacher.

While I on the other hand, am way to used to this stuff...

"Got something." Nat announced, and the Gryffindor first years, who had begun to look somewhat uncomfortable in the silence and out of their depth looked up, suddenly animated.

"What is it Nat? I mean, Professor Carter." Mouse asked, flushing crimson with his slip up. Nat chuckled wryly.

"You may as well call me Nat in here kid – after all, I'm not technically doing this as your teacher. Anyway – from what Minna was saying, and hearing last night I think I might know what it was...but can I check a couple of things first?" he asked

"Sure..." Mouse said, if a touch warily.

"Ok...first off, do you remember anything? That rules out possession, at least."

Mouse gulped, then thought back to the night before. He did remember something at least...nothing specific exactly...

"I felt a really strong need to get where I had to be. And that someone was...singing to me." he blushed.

Nat raised an eyebrow.

"Nothing specific then, but at least you remember something. So that definitely rules out possession then."

Rose answered Becky's smug whispered 'told you so' with a rather haughty sniff.

"Well, that also backs up what I thought it might be, but I have no idea how..." Nat continued, then trailed off as he traced the page he was on down. "Here we are. Siren. An incredibly beautiful sorceress by all accounts, the contemporary of the Hogwarts founders, who specialised in seduction and the use of music in her spells. But how an ancient and long dead witch is calling you out of bed at night I have no idea. But it fits with contemporary accounts of the men enchanted by her at the time, and that combined with the whole unearthly voice thing Min heard...I don't know what else it could be..." Nat sighed, looking frustrated, and Mouse knew that one of the things Nat hated the most as an ex - Ravenclaw was not knowing the answer to whatever puzzle had presented itself. (The other being Minna hiding the peanut butter from him.)

Mouse suddenly became aware of being the centre of attention.

"Are you all right Mouse?" Becky asked first, whilst Minna, Nat, Albus and Rose looked on in concern. You look a bit...dazed."

"I think I'd be a bit 'dazed' if I'd just been told that an ancient sorcerer was making me sleepwalk." the logical part of Scorpius's mind heard Albus mutter. Dimly, as if from a distance, he heard himself say.

"Yeah, I'm fine...I think I need some air." Scorpius said and headed for the door. He heard Albus and Becky follow him out the door, whilst the same logical part that had heard Albus's aside heard Rose, saying 'whilst I'm here Professors, I don't suppose I could ask you a few questions?'

He was dimly aware too, of the fact that Albus and Becky had let him go on ahead, and was grateful for it. He needed somewhere he could process what had just happened to him. He headed to the highest place he could think of, the Owlery, and when he was finally there, and had made sure he was alone, collapsed to the floor, his mind racing now the side of him that Mouse dubbed the 'pureblood' side had finally given in too.

What the hell does it mean? He asked himself How is it remotely possible that I've been enchanted by someone that had been dead for years and years and is making sleep walk through Hogwarts in the middle of the night? It can't be – and what's more why would she be – if she wants to seduce someone, isn't it abit creepy to call an eleven year old to her...it's not like they're aren't people that would be more seducable, if that's a word. Scorpius laughed once, a dry humourless sound, at the thought of a powerful sorceress being chased by an enraged Minna after trying to call Nat to her. As if thinking of her had brought her to him, Minna's voice called Mouse out of his thoughts.

"Mouse, you in there?"

"Go away." he wasn't really surprised, though, when Minna ignored him, and entered the room, wrinkling her nose as she did. A muttered Scourgify later, she sank to the ground next to him, and Mouse, only half-reluctantly, leant into the side of the woman he viewed more as an elder sister, or maybe a close aunt, as she did.

"You have good friends." Minna commented, and Mouse looked at her quizzically.

"They told me you ran off. I remembered you always used to go hide somewhere high when you were upset when you were younger, and I figured you haven't changed that much. So what's up?"

Mouse sighed, and told Minna much of what had been going through his head.

"Hmm." she said, after a period of silence. "It might not be her you know, brat. Or maybe it's her ghost. We don't for sure, you know." She pointed out, in a slightly annoyingly reasonable voice.

"But even so. Why me?" Mouse asked, resisting the urge to grimace at her. Minna had know such hesitation, and pulled a hideous face, drawing a laugh, this time a real one, from Mouse,

"How am I supposed to know? Am I psychic or something?"

"Yes." Mouse pointed out, laughing again as Minna snapped her fingers, somewhat theatrically

"Damn." she said. "But speaking of psychic, I predict that there's four very worried people waiting for you outside. What say you that we go meet them?" Minna asked, brushing herself off as she jumped to her feet.

"They'll think I'm weird." Mouse muttered, staying where he was. Minna raised her eyebrows and pursed her lips.

"You seriously think that the son of the Man who Won, Boy who Lived, what ever, and his cousin are going to think this is weird, considering the amount of stuff their parents got up to?" She asked, scornfully.

"No." Mouse admitted "But Becky might."

"And? If she doesn't want to be friends with you Mouse, then it's her loss, right? It's not like you'd be friendless . Now stop being so silly, and come on. You havelessons now, don't you? And I doubt your teachers are going to be too happy if they found out you're late because you were sulking." This last was said in a mock-scolding manner, although it was somewhat spoiled by Minna's hoisting of Mouse to his feet, and her ruffling of his hair.

"Fine mum" Mouse said, glaring at her, and left the Owlery, where Minna's prediction was proved to be correct. Nat gave him a quick hug, then pushed him over to where Becky, Rose and Al were waiting.

"Where did you go?" Becky demanded

"We were worried!" Rose continued, whilst Albus merely opted for a playful bear hug, which then turned into a half nelson.

"Boys." Rose and Becky chorused as the headed down the corridor, satisfied that their friend was all right. Scorpius followed, his spirits lifting as he realised that he was in fact, not alone.

And I'm not going to let some stupid sleepwalking thing scare me. He decided as he wriggled out of Al's stranglehold, and ran to catch the girls up. Not while there are people who want to help.

In fact, despite the lack of sleep, the rest if Scorpius's day was incredibly happy, and not even the docking of twenty points from Gryffindor and three detentions from Professor Hendricks for blowing a cauldron up with Albus could attract from his buoyant feeling that somehow everything was going to be all right...

A/N Dun dun duuun! Ok... So I lied, no Harry. But DEFINITELY Harry next chapter – yay! But this is actually a pretty long chapter as is, and had I added all the Harry stuff, it would the same length again. And not finished...

I would also like to thank you to the fabulous VI kids I invigilated for last week, who gave me some of the inspiration for the stuff in Nat's office. So thank you Kaneez and Hassan.

Oh and guys, over 600 views! You rock! Oh, and I'm welcome to suggestions you would like to see in this fic. :D Tolrais
