Disclaimer: Unfortunately none of this belongs to me.but if I could choose one thing it would be Severus Snape mmmm.ok drifting now.

I don't think I have anything in there that is mine other than the plot. I know what your going to be thinking when you read the prologue but please carry on reading this is not what it seems all you have to do is read the little bit from Dumbledore's Point of View and things become clearer. I hate to admit it but Severus may be a bit OOC but I've done my best after all he is a hard character to write. There are quite a few flashbacks to start with but that's just so you understand the setting. By the way I have no idea what to call this yet so the name is temporary. If you are reading and have a better name please tell me. I have added two chapters here as they were a little short. So please R/R

Unexpected

Prologue

Severus Snape potions master at Hogwarts School of Witchcraft and Wizardry was at Snape Manor, but he wasn't alone in fact his body was positioned over a climaxing 17 year old. Hearing the moans excited Severus so he thrust hard one last time and began to come while yelling out his lover's name, "POTTER!"

Chapter one-Ten years later

It was two weeks until a new school year began at Hogwarts and Albus Dumbledore had called his staff to a meeting in his office. Last to rush in was Triella Sinerstra,

"So I'm late, up all night looking at stars fascinating constellations you know!" When she had settled Dumbledore lent forward linking his hands together.

"I have asked you all here today so that you may meet the new Defence Against the Dark Arts Professor. Many of you will have taught this person when they attended Hogwarts. I give you Harriet Potter." When Harriet stepped into the room Dumbledore lent back to see how the others reacted. Hagrid and Minerva looked thrilled, Hermione now teaching Muggle Studies looked beyond thrilled in fact throughout the entire room there was only one sour face which belonged to Severus Snape. Dumbledore smiled Hogwarts was going to be interesting this year.

Harriet entered Dumbledore's office with a tingle of remembrance and managed to see a circle of faces before she was jumped on by Hermione.

"Harri, why didn't you tell me? Oh it's so good to see you again!"

"I only found out yesterday Herm. I've missed you so much." Harriet stepped back and grinned at Hermione. It was the same old Hermione at first glance with her bushy hair but looking closer there were some subtle differences, for instance the face shape had thinned and matured not to mention she was actually wearing tastefully applied makeup. Hearing a gruff cough behind her Harriet turned around to see Hagrid. Now unsure what to do Harriet held out her hand and was pulled into a rough hug. So slowly Harriet went round the circle greeting her former professors now her colleges until she reached Snape. Meeting those cold black eyes she froze, gave a stiff nod before moving onto the last person Dumbledore.no not Dumbledore anymore but Albus Harriet reminded herself. Albus said cheerfully,

"Well you've changed. I remember you with black hair, green eyes and a certain scar. Now you own golden hair, brown eyes and are missing your famous feature."

"Yes it's amazing what hair dye, 3o day contact lenses and a cover up charm can do. After all I had to change my appearance before I could release my books." As soon as the words were out Harriet mentally groaned, she hadn't intended to say anything about her other means of income. Albus shot her an amused knowing look before saying,

"Ah yes, the Harry Potter books. It is very clever the way certain details have been twisted, for instance Ron's curtains being slashed instead of Hermione's and a certain Chang Cho's name being turned around. Also I believe you have portrayed me well" Harriet blushed but Albus carried on "In fact why not carry out a little survey? Raise you hands is you have read the Harry Potter series so far." All hands in the room rose apart from Snape's. Harriet by now looked like a tomato and Albus took pity. "Right I trust you brought your belongings with you. Like I said, in the summer holidays you must return two weeks before term begins any other holiday you must return two days beforehand. Now Minerva, Hermione please show Harriet to her new quarters. Severus a word if I may?" Albus sat down decidedly and Harriet followed the two women ignoring the others mutterings and Snape's frown. Indeed Harriet felt quiet bemused; she'd forgotten Dumbledore could have that affect on you.

Chapter two-Memories

As the others left the office Severus approached Albus with a feeling of trepidation. He stood there for a few moments while Albus sat eyes closed before Severus cleared his throat.

"Oh yes Severus, sorry. I wouldn't of kept you behind except for I felt that you disapproved of my decision." Severus felt as he often did under Albus's gaze, uncomfortable, and he replied awkwardly.

"I just wondered if it was altogether prudent to hire someone who is giving Muggles information about the Wizarding world."

"Severus the Ministry has deemed it safe and Harriet has built her cover so carefully that it is impossible for Muggles to tell. To them they are just stories of magic and mischief not to mention completely fictional."

"Right Albus, as always I trust you judgement. I shall see you at dinner." Severus left the office and walked down to his bed chamber. He knew that people often got the impression he glided everywhere but that was only because his robes were long and loose therefore hiding his legs. When Severus reached his bed he let himself collapse onto the green silk sheets and he remembered the last meeting he'd had with the Headmaster over Harriet Potter

Flashback-ten years before

"Severus I must ask you a favour when you go back to Snape Manor during the holiday."

"I will try and comply Headmaster." Replied Severus lazily, he wasn't concentrating properly but thinking how he would be home soon.

"Thank you. What I ask is going to be difficult. Would you please take Harriet Potter to Snape Manor with you?"

"What?!" Severus roared snapping back to attention and raising halfway out of his chair "Albus how can you ask that? You know how I feel about the girl. I can barely stand her in my lessons let alone my home."

"Severus with Voldemort about to make his move at any moment it is the best thing. Here there is to much to do and no one to keep an eye on her."

"If I refuse are you going to turn this into an order?" Severus knew the old man well enough to know that he most likely would.

"Yes if I must"

"Very well I'll take her." Severus said seething

Severus's scowl turned into a smirk as he thoughts turned to Potter's reaction and she'd come storming into his office.

"Sir what is the meaning of this?" Potter yelled slamming the dungeon door.

"Lower your tone Potter. I take it you have spoken with the Headmaster." Severus coolly replied.

"Then it's true?" Demanded Potter

"Yes, under protest." "Then refuse!"

"Do you really think I didn't try?" Snapped Severus "Do you really believe I'd accept you into my home willingly? You must know it is impossible to refuse the Headmaster anything." Harriet Glared at him and rushed out of the office.

End Flashback

Severus sighed and noticed it was time for dinner. Oh goody he thought wryly the defence against the dark arts professor is next to mine.

Harriet stepped into the great hall five minutes late and came to a halt as the other stared.

"Sorry, it took me a while to get sorted." She smiled guiltily.

"Quite alright my dear. Come, come take your seat." Albus waved his wand and the single remaining seat drew back. Looking Harriet let out a soft moan her seat was between Snape and Hermione. At least Herm's there I can ignore Snape, Harriet concluded. Harriet sat with her back to the Potions Master and listened to the convocation Hermione was having with Minerva but after a couple of failed attempts to join in she turned back to her plate feeling slightly put out. As Harriet began to feel entirely excluded a sneering voice reached her ears,

"Is Potter sulking about not being centre of attention?" Without facing him Harriet muttered back,

"No Potter isn't. Listen Snape it's bad enough we have to sit next to each other please don't make it worse by talking to me."

"My my someone is tetchy. By the way you ought to have washed your face before you came down its filthy."

"The talk of washing is rich coming from you. I mean you are the man with enough grease in his hair to fry all the fish in Britain!" Harriet voice rose to a shout and she stormed out of the hall leaving her plate untouched. How dare he? She fumed couldn't he of let it rest just for my first day? She snapped the password to her room 'Puddlemere United' and flounced into the cushy armchair by the fireplace. The Severus Snape she'd seen tonight was the one most often shown to the world, but for a short space of time at his manor house Harriet had seen a different man.

Flashback-Ten years ago on Christmas day

The silence at the dinner table was only broken by the occasional jarring noise of cutlery hitting china. Harriet could stand it no longer this had gone on for almost two weeks,

"Sir I know that we don't get on but seeing as its Christmas couldn't we call a truce?"

"A truce Potter?" Snape raised an ebony brow.

"Yes sir." Harriet took a gulp of water nervously, sure he was about to mock her,

"Well why not it should be amusing." As they ate Snape drank more and more wine, consequently his tongue became loose and Harriet found out that Snape's father had indeed beaten him. To even things out Harriet told him her feelings on being an orphan. Gradually their heads came close together and they stopped talking but stared into each others eyes. To Harriet Snape's black eyes seemed glazed as he lent forward and put his cool lips to hers. Startled Harriet jerked back but his hands were on the back of her head stopping her while his tongue swept possessively into her mouth. Harriet had never been kissed like this, even though she was 17 Harriet was hopelessly inexperienced, but Snape when Snape's tongue began a erotic dance with hers Harriet no longer cared and let her own mouth run wild while letting out a moan. The moan seemed to snap Snape back into sobriety and the glazed look left his eyes. Roughly he pushed away and stalked over to the door. 'Oh no he's going to be mean again' Harriet thought but to her surprise he said,

"Fancy a game of Chess?" The game lasted until the early hours of the morning - as Harriet had greatly improved while playing Ron - but finally Snape won with a vicious Queen. The unlikely couple walked upstairs until they reached Harriet's room. She turned and opened the door and was about to go in when Snape said,

"Potter."

"Yes Sir?" Harriet turned, Snape walked over laid his lips to hers then whispered in her ear,

"Merry Christmas Harriet." Before nudging her into her room and leaving. When she was sure he'd left the hallway Harriet collapsed to the floor, her knees week.

End Flashback

Harriet was abruptly pulled out of her memories when there was a sharp rap on the door. Harriet jumped up and hurried of thinking it was Hermione coming to check she was ok but when she opened the door she came face to face with none other than Severus Snape.
