Swiftly rising from his seat, Albus copied Severus posture and shouted him back.

"SHE'S MY DAUGHTER!"

Now

Blown away by Albus outburst, Severus slumped into the armchair behind him. Even the experienced spy, found himself unable to hide the surprise plastered all over his face at such discovery. A daughter! Severus could always rely on Albus to be able to pull the rug right from under his feet.

For what he have been hearing, the girl should be sixteen at most and Albus was about to turn one hundred sixty eight! It seemed Dumbledore wasn't gifted with just great magic abilities!Oh no, I really don't want my mind going over there, he thought frighteningly.

More importantly, how and why, did he keep his daughter a secret? He could understand why he would want to keep her in the shadows, hided from all his enemies, but hid her from the very same people he claimed to trust?

But, in a way, he did understand the wizard's reasoning. After all, a secret merely stays a secret when it's known by only one person.

I wonder who her mother is.

Righting himself on his seat the double spy, with his stoic mask already back in place, affirmed more than asked.

"I suppose then that the emergency meeting would be for you to try and redirect the Order members scanning as far away from your daughter as possible before disappearing with her again. Did you need my assistance? Was that why you needed to talk to me before the meeting?"

But, even so, that don't explain what he could want me to teach the girl.

Seating himself again, Dumbledore took off his half-moon glasses to pinch the bridge of his nose before putting them back on.

"I truly would like for that to be the case but..."

Again Severus found himself surprised by Albus actions, but now he was more alert and didn't allow for it to show. Could it be possible he had just seen not only sadness but also guilt on the other wizard's eyes? What was the Headmaster planning to do?

"Severus I need your aid in teaching Serena everything she will need to know to be able to defend herself in a duel or fight."

Shocked from what he could perceive being Albus plans towards his only daughter he saw himself losing grip of what little understanding he could thought he had manage to get about Hogwarts Headmaster way of thinking. Could it be possible the older wizard was thinking in using his daughter as a mere pawn in his battle against the Dark Lord? If that was the case, why hid her until now? What had happened to make him take such a potentially disastrous decision?

"Albus, you can't be seriously thinking..."

"It's the safer …"

"It's too public; the risk is simply too big. You know how much death-eaters spawns are inside Hogwarts walls! Why did you keep her in secret if you were simply going to throw her to the wolves?"

"It was her own choice, she's old enough to know what she wants and I'm wise enough to not try and stop her."

It was in times like this that the dark professor could come close to believe in Voldemort when he said to all his followers that Dumbledore was nothing more than an old fool.

"Albus, please, you know as well as I that you did the right thing maintaining your daughter a secret, if word of this gets out she will be a target as important as bloody Potter. The Dark Lord will be more than tempted to use her against you. Do you really want to put your only daughter in the eye of the storm? The boy is nothing more than a danger magnet and probably would be dead already if it wasn't for his annoying friends, so she would be better off away from him. You should simply put her in whatever place you had been hiding her all those years again."

"I have already decided Severus, Serena will come to Hogwarts on the principle of the semester and you will help her to learn all she need in how to protect herself, you wanting it or not."

The look Dumbledore cast Snape's way was more than enough for him to know he wouldn't be capable of change the old wizard's mind. Snape had known, even from the very beginning when he had made that oath, which Dumbledore only cared for him as long as he could bring him information about Voldemort's planes. But now he couldn't stop from wandering if the manipulative sorcerer cared about anyone at all. Wasn't the old man putting his only daughter in equal danger, and for what, for leveling the power balance in his favor?

"As you wish Headmaster, but don't come crying to me when he sends you your precious daughter as nothing more than body parts."

Turning his back to the misunderstood wizard the potions professor didn't manage to see the painful look Dumbledore cast his way. The headmaster knew very well the thoughts that passed through his ex-student's mind, but he couldn't do anything to make him see the truth about his actions. He cared deeply for his beloved daughter and for the ex-death-eater as well, but certain things must happen, he wanting it or not.

"I'll be waiting in the meeting room for when you decide to go thru with this nonsense. "The potions master said without even looking Albus' way before leaving the office.

…...

Exhausted Dumbledore let himself fall on his armchair, the meeting had been strenuous. Passed the initial chock when he drop the bomb and finally told all of the Order about his daughter all hell broke loose. He managed to calm down everyone enough to explain everything. In the end they had finally depart leaving him their best wishes for the girl's health.

Putting aside the achiness of his body the elderly wizard got himself up from his seat. Although tired, Serena should be waking up by now and he needed to explain everything to her, his rest wasn't important for now.

…...

She was naked in his bed waiting for him and he could see through her eyes how much she lusted for him, despite the fact that all his body was screaming at him to take her now, he remained standing still in front of the bed.

After so long he was finally achieving what he always wished. Now he finally allowed himself to admit what deep down he had always known, that he had desired her from the very first time he have laid his eyes on her, even in the beginning when he have faked indifference and scorn, but now she finally would be his.

His look become ferocious, he knew how much she was desired by both sexes she was the most beautiful sorceress he ever met and her intelligence, had been as much of a shock as it had been refreshing (as much as someone like him liked the fact of being the most intelligent person of all of them he had to admit that it was a bit more than irking the fact that none, not even among his followers, could even start to try to understand his theories to the development of the spells that he created), she was perfect therefore it was natural for her to be by his side, after all, he was perfect too.

He was deprived of its thoughts by the needy moan that came from the bed making him smile, a predatory smile only use by a predator about to embark in his hunt. After magically disrobing himself he placed his white wand (meaningfulness of horror and death to many) on the bedside table. Before she could realize what was happening he pulled her under him making her give another moan and consequently turning his already large erection even bigger.

"Shush my pet after all the waiting you put me through I think I have the right to taste you entirely" he said before finally taking her mouth in a completely dominating way. Nothing of what he had imagined could ever compare with the taste of her mouth or the heat of her body as he glued his body to hers, he wanted to taste her, to take her by any possible way, to brake her and put her back together again, he wanted to consume her entirely until he was the only thing in her world.

Finishing the kiss he noticed her shuddering and trashing beneath him, yes definitely his little witch was a wild cat. This time he turned his attentions to her ear nibbling it and kissing her jaw line.

"Plea… please." She begged him.

"Calm down, the best of things must be savored slowly" he responds grabbing her left breast and starting playing with her nipple as his hungry mouth found its way to her other mound. He would show her all the pleasure he could give her, the pleasure that no other would ever be able to give her. Yes, he would leave her mad of delight and she would see that he was the only one for her. With the predatory smile back on his face he opens her thighs and settles himself between then thinking.

Finally, after so many years of waiting, you're finally mine.

Investing he reached how big was his conquest when he brakes a barrier making its prey moan in pleasure and scream in pain. Yes this sure was going to be a night to remember, he couldn't, possibly, expect for more, she haven't belonged to any other and now that would never happen.

Feeling her moving underneath him searching to increase their proximity he grabs her by her waist and fiercely penetrated her going faster and deeper with each stroke, his touches igniting a fire in her she could no longer ignore, hers increasingly high pitch screams of pleasure were certainly more than enough proof of her impending climax, speeding his pace he thought, this time nobody will take her from me, nobody will ever going to take her from me again.

Finally he penetrated her as deeply as he possibly could, exploding inside her.

"HELENAAAAAAA!"

Red eyes opened in darkness. Only a dream, Dumbledore had made sure of it. But he would have its revenge or he wasn't Lord Voldemort. Yes and it would be quite sweet, oh so very sweet. The burst of laughter that followed could have terrified even the bravest Aurors.

…...

The well-known know-it-all Gryffindor looked amused as Ron and Ginny bickered with each other annoyed with the fact they had to help their mother cleaning the Headquarters and couldn't use magic to do so.

The fight clearly being just one more of those silly fights amidst so many others the two siblings had shared between them, it didn't worried or even bother Hermione (by dinner time they wouldn't even remember the cause for it) only making her silently laugh to the reasons each other presented to the other to convince him/her to do their part of the work as well. But Hermione joyful mood was short lived; the playfulness completely faded away from the Gryffindor princess eyes when she turned her attention to Harry.

She had noticed her friend had been even more silent these few days since he had arrived to Grimmauld Place than what he had been thru the last four years she have known him and that had made her increasingly worried about her friend. How could she help him if he wouldn't tell her what was wrong?

At first she had supposed all that was because of last year's events and the upcoming of his audience, but as the audience had ended without trouble for him and the way she continually caught him, looking worried towards the room given to the Headmaster's daughter, she finally understood what was keeping his mind busy these couple of days. He was worried about Dumbledore's daughter health!

The girl's true parentage caught everybody by surprise, after the meeting two nights ago the news spread like fire making everyone aware of whom the unknown girl really was and the gossip was running high these passing days.

He couldn't simply keep all that anxiety closed deeply inside of him; it would only end up hurting him she was sure.

That's it. He's going to put all that guilt out of his shoulder and it's going to be now. She thought to herself as she pried her friend's darkened expression when he again looked in the direction of the girl's room.

"Harry?"

"Hmm, sorry Hermione were you talking to me?" The tormented boy asked as he turned to his friend.

"Do you think Dumbledore's daughter will be all right?"

"I sure hope so; after all it was because of me that she got hurt." He said with a guilty face.

"I wonder who her mother was," Ron interjected.

"Ron that doesn't concerns us," Hermione chided.

"Come on Hermione I don't believe that you're not at least a little bit astonished by the sudden appearance of Dumbledore's daughter."

"Ron I'm sure there was a reason, for the Headmaster to keep secret about his daughter until now," Ginny acknowledge.

"Gin is right, we all know how secretive Dumbledore is about his personal life and if he hid his daughter all this time he must have good reasons for it," continued Hermione.

"I only know that if it wasn't for her, I and my cousin would probably be dead by now."

"I still can't figure out how she managed to destroy five dementors without a wand." Ron mumbled thoughtful being aware of what really had happened by Harry's narrative.

"She's Dumbledore's daughter, what did you expect?" Hermione responded as if that was the most natural thing in the world.

"Hermione, you're always the same," the other three said in chorus making the four of them laugh their socks off.

With the playful mood back, Hermione, as she perceived the end of her friend's depressed state, said laughing, "I am aren't I!"

…...

After her first encounter with the Headmaster...her father, she needed to get used to call him father, he had insisted on it.

After her first encounter with her father she had waked up to find him seated in the same armchair from before engrossed in what seemed to be some important documents dropped all over his lap, a new table at his side completely buried in various stacks of even more papers.

She was incapable of noticing anything more before he realized her state of awareness. Immediately putting the documents aside, he tenderly asked, "feeling better?"

Getting into a seated position the blond nodded her head affirmatively, "can I please get a glass of water; my mouth feels like cotton!" She said in a raspy voice.

"Of course," he said before rapidly getting up from his seat to pick up a goblet from the nightstand. "Here you go, take small sips so you don't choke on it." He oriented as he gave her the chalice.

"Thank you."

Seating himself again he asked her, "do you think you are well enough for us to talk a little, I know you must feel exhausted, but I promise to only take a bit of your time."

"Okay."

"I'm sure you must feel very confuse with the turn of events, but before anything else I want to assure you that you shouldn't feel obligated to accept what I'm about to ask of you. Firstly because all that happened with you and the other two teens wasn't your fault. Voldemort was bond to attack Harry as soon as he could."

"Voldemort?"

"Of course, you don't know who he is. Well, this will take some time."

Time Lapse

"Poor Harry, I can't even begin to imagine what he is going thru right now. And you say this Voldemort fellow came back to try to finish what he started fourteen years ago? How can I help?"

"Calm down my dear before anything else I must warn you, if you accept to help us in our war, although I will be doing anything to maintain you safe from harm, you will be in grave danger every step of the way. Please let me finish," he cut her off before she could say anything. "I don't what you to think I adopted you only to use you in this fight, I didn't. And if you want I can put you in a safe house until all of this is over. Is that what you want?"

Serena looked right into the old wizard eyes and didn't find any trace of deception, was he truly proposing to left her out of the war? Even when he seemed to need her help? Why was he being so comprehensive and understanding towards her feelings? Even if he had decided to adopt her wouldn't it be normal for him to expect for her to aid him in whatever he wanted? Every time she talked to her father she only managed to get even more confuse than what she had been before.

It would be nice to be able to turn a blind eye to all that was starting to happen all around both muggle and magical word, but...could she really turn her back to the very same people that, until now, only helped her? What kind of person would she be if she did something like that! Sure, she could say that wasn't any of her business ,but that was just it, it was her business after all if what her father had told her about Voldemort was true she would be one more thing the dark wizard would want to get rid of. And Harry, she barely knew him but he hardly known her too when he had risked himself to help her. He could have turned his back at her then, but he didn't.

Albus saw as the conflicted thoughts fought for supremacy around Serena's head.He already knew what she will be answering him, but he was wishing whit all his might for her to not tell him the words she was about to proclaim. As much as he knew they needed her he wanted her safe.

"I will help with whatever you may need."

And so her destiny is seal!The elderly wizard sadly thought.

With a solemn face he nodded his understanding- "Very well then, we have much to discuss."

…...

Serena had passed the next two weeks, since she had taken her decision, in bed and Poppy (a cheerful medi-witch that had been delighted to meet Albus' daughter) had insisted that she stayed in bed until after her complete recovery. Serena was sure she would have got out of her mind if it wasn't for the piles of books completely surrounding her bed.

She sighed relieved as she, finally, ended the last book and put it back down on her overflowed bedside table. As her eyes laid down on the variety of flasks all around the small table she couldn't stop from grimacing. It was true all those potions were only for helping her to rapidly and completely recover, but...she hated taking medicine, she always had. And did they all need to taste that bad?

Shaking her head, the girl scoop the diamond shaped bottle with a greenish liquid inside and swallow it as fast as she was able to. Using all her will not to start sputtering the foul tasting potion all over the bed clothes she returned the bottle to its original spot only to see the flask refilling again.

No. Serena thought discouraged. I had hoped this would be the last time.

Her father had explained to her the potions flasks she needed to regularly take would refill themselves after she taken the potions until she wouldn't need to take them anymore. A safety measure, he said, so she could use the time-turner without worries. (!)The shifts in her thought lead her to turn her attention to the small object attached to a misleading frail looking silver chain, currently dangling from her neck. She still could barely believe the little hourglass-like trinket was really able to reverse time, even if she had been using it for some time now.

Her father had lend her the magical object after explaining to her she would, without a doubt, need it to be able to learn all that she needed in such little time. At first she didn't see what the big deal was, after all she was sure the two dozen books or so that her father had brought her weren't nothing she couldn't handle in the month she had until the start of the new school year (being forced to stay in bed for Merlin knows how much time, she didn't thought it to be very hard to do) but, as she learned all that she needed from them in little more than two weeks her father had promptly brought her another (much more larger) pile of books she would also need to read and memorize and that had been only the tip of the iceberg. Now, having lost track of how many books and rare manuscripts had passed through her hands, she understood why her father had untrusted her with such a special item.

Suddenly feeling lightheaded and sleepy, a secondary effect from the potion she had just took; she accommodated herself in the large bed letting unconscious take over her.

…...

"I don't like lying" said Serena holding the box Dumbledore had delivered her upon his arrival.

"I know Serena but this is the best solution for all, it will be much safer, but the choice is yours Serena, what did you say?"

"Very well father" said Serena to Dumbledore who was sitting on the same armchair of last time, to Serena's right stood a tall man with shoulder length black hair and equally black eyes that made her think about a black hole. His mouth had thin lips and his large nose gave him a somewhat austere look.

"Serena this is Professor Snape, he's the Professor I have talked with you about, we both will teach you everything you need to know to be able to protect yourself without any problems. First things first, it's better if you open your present before we begin."

Only then Serena thought about the box that Albus had given her at his arrival.

"It's beautiful" said an astonish Serena gazing at the delicate wand she found inside the wood box.

Contrary to what was common the fragile looking wand wasn't a wood wand like any other seen in the magical world that she had been reading about, that one was made of some sort of crystal.

"It's your wand Serena, take it go on, it was made especially for you. I put a spell on it to seem like a simple yew wand. You will be the only able to see its true form."

The wand illuminated itself with a flash of light the moment she took it in her hands, after a few minutes the brightness decreased, but its core continued to shine.

Serena diverted her attention from her father to the professor "it's a pleasure Professor Snape thank you for your time, I am sure that a person like yourself must be very busy," she said, trying to sound as grateful as she felt.

Serena's greeting caught the potions master completely of guard, in a try to hide his surprise he decided to give her one of his snidely remarks, "like you have just said, I'm a very busy person, and because trying to teach a spoiled brat is a waste of my time I pretend to dispatch this the fastest way possible." Snape realized his remark had hurt the girl, but instead of starting crying or beginning to scream at him she silent nodded for him to continue. Had she been used to degrading remarks,he asked himself surprised, a frown deepening in his features.

"I have to leave for now; I will leave you two with your lessons" said Dumbledore before rising to leave.

"Professor, when do we start?" A determinate teen turned a hardened gaze to the dark wizard.

…...

After a more than a little bit surprising lesson with the girl Snape had returned to his house at Spinner's End. Before going to bed he decided to take a drink to clarify his troubling thoughts. The very first thing he tried with the girl was legilimacy and he couldn't be more surprise with what he found out.

He was incapable of reading her mind, not a single glance of a memory, a bit of a thought, nothing. It was as if he was trying to read a brick wall. At first he had thought she was occluding her mind and effectively putting a stop in his attempts, but soon enough he shun that thought away. No, she wasn't using anything to stop him at all, whatever it was that was blocking his spell; she wasn't the one responsible for it.

Leaving behind his failed attempts he had tried to evaluate her, until now, dormant magic only to be surprise yet again by her apparent increasing power. That shouldn't be that way; a wizard or witch are born with their full power, they simply have to learn how to tap into it and learn to tame it. There were objects used to increase someone's magical power, but they were extremely rare and she wasn't using any. So, from where this increase in her magic was coming from? He took a swing from his glass.

The brooding wizard didn't have a clue, but he sure as hell was going to found out.

…...

Albus petted the mystical bird he had as a familiar as he scanned all the papers for a last time. It seemed all was in order; any trace of Serena's past had been completely erased, as it should be. Lining back on his armchair the ancient wizard gave a tired sigh as he look thru his office with unseeing eyes. Severus had believed his story about how he had kept Serena in a safe-house for all those years pinning down her magic and erasing her from Hogwarts files to keep her safe as he knew he would not even being surprised to know she never had a wand before today when he had gave it to her in front of the potions Master. Serena had been aware of the version of the facts he had told Snape by a conversation they both had shared earlier on, before the Professors arrival.

All was set, now he only had to wait.

(!) I'm not sure about this but; all that I've read about time-turners led me to think time passed for the person who used the time-turner differently from anyone else so the flask of potions refilling it was a security major so Serena wouldn't stop her treatment in case Dumbledore couldn't reach her in time.

A.N. Any doubts just ask. Bye and hope you have enjoyed.
