Side story: part two

The ambush

The corridors of Hogwarts seem so empty and lonely as majority of the students were all gone now for the holidays. Isabel's heeled shoes and the paws of the dog beside her were the only one sounds could be hear on the hallway.

The two went straight on the headmaster's office where Albus Dumbledore were on his desk waiting for them to arrive. His eyes twinkle at the sight of his visitors.

"Albus, it is time"

Severus grumpily went his way to the headmaster's office, clutching several vials on his hand. It was already Christmas holidays, yet he was still there because of the stupid plan of the informant. All he wanted to do was slumped on his so called house and drowned himself in firewhiskey and wishing he would just woke up the next year.

Next year, and that Renee Ann Matte will not be here anymore.

He was angry, no he was beyond angry, how could that girl go here and just decided that she won't be coming back? How could she leave when she was finally adjusted on the school? But Severus was angrier to himself. How could I make the same mistake again? I just pushed someone away! Feeling this way to a certain student was beyond him. Feeling, I don't have the right to feel this way since I was the one who drive her off. Yet he can't stop himself on thinking about that certain muttered the password and entered the office.

Albus must give a good reason for calling me.

He found the headmaster was not alone. Severus eye's narrowed at the sight of his visitors. A woman on dressed on dark green robes, her brown hair was flowing freely on her back and has piercing green eyes. She was also eyeing on him, and the dog beside her was growling at him. He knew the woman, in fact Severus always see her on death eaters meeting.

What in the name of Merlin?

Albus looked at the two parties, worried at the next scene he would see next. Where is Minerva anyway? She needs to come here now, he signed. He knew how hot headed Isabel could be, especially when questioning her loyalties. And Albus knew how Severus's sharp tongue could be especially with Sirius with them now. They weren't a good combination to be on the same room.

This couldn't be a good sight.

"Headmaster" called Severus, still staring on the woman a few feet from him.

"Ah yes, Severus come here" Albus called, trying to keep his twinkle on his eyes.

Severus consciously went nearer on the headmaster, his eyes were questioning on the visitors with them.

"You must be knew him Isabel, this is Severus Snape" Dumbledore introduced the man at her.

"Ah, yes. I knew about him" Isabel raised her eyebrows as she reached the man's hand to shake his. Sirius growled beside her.

Severus shakes Isabel's hand. Things were not really sinking into him.

"What is the meaning of this headmaster? Why is she here?"

"She was the informant I was talking about" Severus arched up his eyebrows in surprise. It doesn't even this idea pass through him; this woman…one of the members of the inner circle was a spy?

"Your informant was another death eater?" the statement made Isabel narrowed her eyes.

"Yes, do you have the polyjuice they needed? They were doing the plan tonight" Dumbledore answered, keeping the conversation as safe as possible.

"Yes this informant he was talking about was a death eater. Are you questioning my…loyalties?" she asked the man. Isabel hated questioning her loyalties, and to add it up it was Severus Snape who was questioning her.

"She is the dark lord's mistress; I can't be just accepting that this person was on our side that easily" Severus spook to the headmaster instead on the woman asking him.

"Do not question my loyalties, you do not have the right" Isabel stood up.

"I have all the reasons to question your loyalties as I am the spy on the dark lord, Isabel, or should I say, Mistress Emily" he sneered. Albus touched his forehead with his hand.

He had already done it.

Nobody saw Isabel moved from her spot, but she had disappeared from there and now on Severus's back. Her left arm struggle his neck and her wand pointing his back. Severus wand was now pointing on her behind.

"Doesn't even occur to you that maybe, just maybe… there is a spy before you? I was already a spy even before that kissing the dark lord's robe was a privilege for you" She whispered on his ear, making her words as slow as possible.

"And why should I believe you?" Severus seemed to be pretty calm to the situation. Sirius was already transformed to his human form and grinning widely at the scene; Albus was staring at the two, with his hand still on his face in disbelief.

"Isabel…Severus please" Albus called, but she didn't mind him. Her eyes were still fixed on the man on her arm.

"Who do think was the one giving tips while the dark lord was locating the potters and Longbottoms? Didn't you think the information you are giving to the order before was not sufficient enough to let them live for a year?" she sneered.

Severus stiffened at the revelation and looked at the headmaster.

"Do not give too much credit to yourself just because you changed sides with Albus protecting you, Severus Snape" she released her grip on the man and sat on her chair again. Sirius, on his human form sat across her, still having a grin on his face.

"Stop grinning Black or I might turn you into a ferret again" Isabel said to the man in front of her. Sirius just rolled his eyes, but still amused by the surprise expression Snape had earlier.

Albus signed heavily as he sat on his chair.

"I am a spy to the dark lord ever since I joined the dark circle. I was the one who are giving information before you changed sides" Isabel explained warily at Severus.

"And do not…call me that" silence filled the room. Severus looked at his mentor's eyes. Albus nodded to confirm what she had said.

"You have a child with him"

"Yes"

"Where is…"

"I think she was already on her way home right now" Snape curtly nodded on the woman.

"The child haven't met his father"

"Yes, she still doesn't know because she was still not prepared for it. We need to get her ready for that. Her mark will automatically appear on her seventeenth birthday." Isabel plays her wand in her hands, a gesture that she was making when she was uneasy. It was a topic she was avoiding to for many years.

"Severus, the only ones who knew about the child's heritage were me, you and Sirius" Dumbledore was the one who spoke.

"And I assume that this child was in…"

"Yes, she just transferred here last September" Severus frosted from his spot. The only one who transferred here was…no, that innocent looking girl was his…

It was as if Severus body had been splashed with ice cold water. How could such an evil man produce a child like that? Severus knew how good Renee Matte was, she was against in bullying and defending her friends as possible she could be. She was just a normal witch. He couldn't help but wonder if that revelation were true. Those innocent laughs she was giving to people around her wouldn't give him any reason that she might be the missing heiress of the dark lord.

"No one should know about it. I don't want her to hear it from other people" Isabel spoke softly, thinking about the safety of her daughter. If they were just given other circumstances, she will run away with her daughter, keeping her away from the dark forces until her bit of her magic drains for that cause.

But no, she couldn't do that, the child's fate was already written. And she couldn't do anything about it.

The four adults turned as door opened and revealed Minerva McGonagall and Nymphadora Tonks. Minerva eyed at the people on the room, Isabel has this grim on her face, Sirius was obviously smirking, Albus has those twinkling eyes again and Severus was has this far look on his eyes. She couldn't help but feel the heavy atmosphere the room was giving.

"Isabel, Sirius" Minerva greeted the two visitors. Isabel smiled timidly at her old friend and Minerva could see it wasn't really reaching her eyes.

"Well, we are complete now. I think you should tell the plan now Isabel. Lemon drops?"

With Isabel's vision, they learned that the kidnapping will be done today. Tonks will pretend to be the girl they will kidnap, with the help of the polyjuice Severus made. Isabel, Sirius and Minerva will be on the hiding and ambush the death eaters before they could advance any moves before them.

A simple plan, yet still dangerous.

"Remember not to kill them. We need know who their master is" Albus reminded at the two. Isabel nodded at her mentor, though she wasn't sure is she could obey those.

If anything happens, she needed to kill them at once.

"You can't come with the mission Snape; the order couldn't afford to lose two spies at the same time. Your polyjuice was enough help for us" Isabel informed the man before they proceed to their mission.

"And who was the one protecting Miss Ma…I mean Miss Renee?" Severus made his face as the usual as it could be, stern and expressionless. His lips barely moved as he speaks her name, yet her name seems to be so foreign on his mouth.

"They send Lupin to guard her" Isabel was obviously not happy on the situation as her mother's instinct kicking again though she was more curious on the man questioning her.

Why would he worry about her?

Snape raised his eyebrow, noticing the grim on Isabel's face as she mentioned Remus Lupin. Why did they send a werewolf to guard her in the first place?

"It seems to be you're not happy on the arrangements. I could place the werewolf on guarding the girl" Severus spoke in his usual business matter. Isabel narrowed her eyes on the younger man and glance on the headmaster. Dumbledore seems to be also surprise on Severus.

Isabel signed and gazed at the man. She wasn't still able to trust him, but she knew Renee would be safer if Snape replace Lupin on his post. She didn't like the idea of werewolf near her for any reasons for that matter.

"Fine, you could replace him" Isabel finally said and ignoring the complaining Sirius at her side. She handled a piece of parchment on him.

"That's the apparition point and the address of the house. My house elf will meet you on the apparition point. You will not show yourself on her for that matter. I guess you could do that simple request"

Severus took the parchment on slid it on his pocket and curtly nodded on the woman. The idea of seeing the girl makes his heart beat fast for he doesn't know the reason. He didn't even know why in the name of Merlin he volunteered on the task.

Severus found himself on the middle of the forest. He casted a notice-me-not spell on himself as soon his foot touches the ground. As like Isabel had said, a house elf was waiting for him on the forest.

"Professor Snape?" Severus nodded on the house elf.

"Please follow me" Toby the house elf said, casted a notice-me-not spell on himself and lead him out of the forest.

It was a long walk, and Severus was glad that he casted the charm as he noticed that the neighborhood was full of muggles. He didn't know the reason why would Isabel choose to raise the dark lord's heiress on a muggle neighborhood. They stopped in front of the blue house.

"This is the house professor Snape" Toby squeaked. Snape nodded and looked around, he found Remus Lupin hiding on the tree and surprised on his appearance.

"Snape" Remus Lupin was surprised on the man.

"Lupin, Isabel send me to replace you" Severus said as he went near on the man.

"Oh" that was the only thing Remus had said. He knew Isabel doesn't really trust him, for he was a werewolf, as a matter of fact…she merely trust any of the members as only a few people knew about her. He had only met the woman because her child needs some protection outside Hogwarts.

"The headmaster had told me that you go straight to Hogwarts and help on the mission" Severus curtly said.

Remus just nodded to his companion. He was still astonished on his appearance.

"Alright, I should go. This place was still haven't found by the kidnappers, so the house was still safe. You could just send a patronus if you need some help" Remus said before walking away towards the apparition point. And Severus was now alone as Remus leave him and Toby went inside the house, leaving him food beside him.

After an hour, Severus frosted on his spot as the girl he was protecting opened the door with a book on her hand. She was wearing muggle clothes and smiled as she shouted inside the house before heading outside.

Insolent girl! Why is she going outside? He thought to himself and casted disillusionment charm on himself and followed her. He was livid; this careless girl was going outside while the order was doing their best to protect her.

He followed her until they reached the park and he made a safe distance between them. Severus saw the girl smiled and signed contentedly as she sat on the bench and gazed on the children playing on the playground. He saw the innocent green eyes gazed at the children with envy. What could she be thinking now? Severus was still can't believe this fragile looking girl has the same blood as the dark lord. Granted, she was even wearing muggle clothes and leaving on a neighborhood surrounding muggles!

He couldn't help but stare on the young girl on the bench who is now currently reading a book. Her dark brown hair glows on the sunlight and her coat covered her curves. Severus snorted to himself, a muggle romance book, he noted as he saw the title. He can't help but to be amazed on the young witch, and didn't notice the softness of his eyes becoming.

"Why did you send him to Renee?" Sirius demanded while hiding on the bushes. He can't believe Isabel trusted that git. It was the man who revealed the prophesy to Voldemort, which lead to his best friend to die, the person who lead Harry to be an orphan. Isabel trusting Snape was the last thing he thought would happened.

Sirius knew how Isabel distrusted people. Nobody knew her whole story, how or when she did became an official member of the order. The old Emily (also known as Isabel now) had a perfect life, an aristocrat…many boys were chasing after her and many girls were envy with her as far as he could remember before, and nobody knew why she chose the path as a spy…besides Dumbledore of course. Even now, only a few people knew she was alive and living on muggle village, with a daughter.

It was only an accident when he found out that Isabel's child true heritage. He was just merely exchanging letters with his godson that Harry mentioned on the letter about the weird feeling he was having when he touch the new student. He didn't mind those, he even told Harry that maybe he was just feeling infatuated with the girl to lessen the tension on the boy. But he did made a research about it as he knew that Harry's weird feeling always up to no good. He finally found out while snooping to Isabel and Dumbledore that Renee was really Voldemort's daughter.

"Could you please focus on the mission on hand? Snape won't do anything to her" Isabel said and rolled her eyes on her companion. She couldn't still comprehend why Dumbledore left the man under her care. He was immature and single minded that they merely got along since the first day. She even transfigured him into a ferret on her first week with him on the house.

"Are you sure he won't do anything? For all we know he had already sent her to V…"

"Damn it Black don't say his name! Doesn't it even crossed to your single way mind that I might have foreseen it in advance before I handed Renee to him? You're impossible!" she hissed and run her hand through her hair. Why do have to be partied with him? I should have gone with Minerva instead.

A girl with braids appeared and the two shut up from bickering. It was Tonks in disguise. She glanced at the two hiding companion and curtly nodded. They made their wands ready, waiting for someone to arrive. Surely enough, a woman with black robes were following her...just like Renee had dream about. They waited until they petrified Tonks and called the man to carry her.

It was their cue to come out and ambush the two wizards. Hexes and curses were all around as they both pointing the two kidnappers and ennervate Tonks to help them. The two run for their lives, on different directions. Isabel and Tonks run after the girl and the other was Sirius.

"Everte Status!" Kaydeem shouted making explosion behind her but didn't stop running. Damn it, they knew about our plan! She thought.

"Expelliarmus!" shouted Tonks, dodging the explosion and tree falling on her side.

"Bormabarda!" shouted Kaydeem, and this time Isabel doesn't dodge the branch of tree that fell on her shoulder. She yelped in pain as she removed the debris of branches piercing her skin, but still didn't stop chasing the woman.

"Stupefy!"

"Aresto Momentum!" the spell made Kaydeem slowed down from running. Isabel and Tonks were finally on her side and as Isabel pointed her wand on the woman's neck as Tonks made ropes appear around the lying woman and tied her on the tree.

"You traitor!" shouted Kaydeem as she saw the woman in front of her. Isabel's eyes narrowed. Damn that branch! My charm just lifted!

"He was right, you're a traitor! You bitch! You will die along with your daughter!" She shrieked at the woman.

"Who is your master?" Tonks questioned her, still on her disguise.

"I will never reveal my master, you bitch!"

"You better reveal it if you want to preserve yourself. The dark lord didn't order you this, didn't you?" Isabel asked calmly on the woman as her wand was still on her neck.

"Ha! And to thought you are loyal to the dark lord, you don't deserve to be on the inner circle!"

"Sectumsempra!" Isabel shouted making Kaydeem yelped in pain, as she felt daggers were slicing her body. Tonks was surprised by the spell, yet she still didn't withdraw her wand at the tied woman.

"I'm getting impatient Kaydeem! Tell me who your master is!" Isabel shouted.

"And you think you could escape from being a death eater because you just changed sides? You will die before you could escape, remember that…" she said with a sly smile, even though she was already heavily injured. Tonks noted that the woman was already insane, like the ones that stayed on Azkaban.

Then as their dismay, Kaydeem was trying to apperate herself.

"Aveda Kadabra!" Isabel shouted before the woman could disappear. Green flashes were all pointed to the woman and she screamed in agony. The woman hanged her head as her life disappeared on her eyes. She released the ropes from the body and the body slumped on the ground.

Remus Lupin and Minerva McGonagall run into her as they heard the shouts and spells. The two saw Isabel and Tonks, looking below the bloody body on the ground.

"Are you two alright?" Minerva asked at them, Tonks nodded at her while Isabel's eyes were still on the body at the dirt. Remus checked the pulse of the woman and found nothing. He looked at Isabel in awe; he found her eyes so cold staring at the body. It was like she was already used on killing.

"She saw me. She was trying to apperate so I have to kill her" Isabel said, not tearing her eyes away from her prey. Minerva could feel the coldness of her voice; it was like the body on the ground, lifeless.

"Your arm's bleeding" Minerva noted and Isabel finally noticed the gushing blood on her shoulders. She blinked several times as she touched her shoulders.

"We could fix those later. We need to find Sirius, he's chasing the other death eater" she said, as she put another concealment charm on her face before running. Her stance was already out of balance, making Minerva run into her and let her lean on the woman on her.

"You already lost a lot of blood. You need to get healed. Remus and Tonks will follow him, I'll inform the headmaster to get reinforcements" Minerva said in her professor kind of tone to make Isabel follow her. Tonks and Remus nodded and run further the woods, leaving Minerva and Isabel.

Sirius cursed under his breath, he had almost captured the man yet someone hexed him from behind making those deep gushing wounds all over her body. He didn't even saw the person who did it, and he was frustrated on it. I will kill that person whoever he is! He thought angrily.

He found himself to apperated on the forest on the neighborhood where Isabel and Renee were living. Damn it! I suppose to apperate on Hogwarts! He looked around. It was already dark, and he was not feeling well enough to apperate again. Sirius had lost too much blood that his surrounding was now circling around him. He clings into the tree making the tree smudged with his blood. He twitched in pain as to find out he just broke his leg. Damn it! He cursed silently. All he could do right now was to alert Severus on his hiding (even against his will) and hope that the git will help him. He reached the small road; lights of the vehicles passing make him see his surroundings.

I didn't escape from Azkaban just to die here, get a grip Sirius! He said to himself as he heavily leaned on the tree with his breath begin to fasten. He transformed into his animagus form and collapsed on the ground.
