Chapter 2 : Of desires and actions – Wizard London – November 2006

Artémée Wildbird & Spencer Reid's adress – Rowena's path – Wizard Notting Hill

The night was hot and the little girl was tossing in her bed, trying to find a spot that would be cool enough to allow her to sleep when they striked.

Dressed in black robes and masks as pale as death, they entered the house and destroyed her life.

Her father died first, a single, final scream of agony escaping his lips just as his body went still. Her mother took his place under the Cruciatus curse after that and she hoped she wouldn't abandon her too. In the end though, as all people do she died and left her little girl alone. One of the men ripped her pink little nightgown open then and pinched one of her nipples. She sobbed.

Shut it, he spat touching the most intimate part of her body. Your parents were traitors. They didn't deserve to live. I will teach you what real, pureblood wizards are made of. And you will live.

After that, he violated her, letting her scream until she couldn't anymore because her throat was too sore. She wished for death then, but it never came and when they all had taken their turn, enjoying her, they left her behind. Weeping, she took her parents' hands and closed her eyes, letting a young woman open hers in her stead, years later.

Artémée was still screaming when she opened her eyes and she took several breaths to calm herself down. It had been years since she'd last had that dream. It had haunted her childhood and early teens before she'd learnt and mastered Occlumency and closed her mind to it for what she'd thought would be forever. But she was tired and sad and heartbroken and she wasn't sure she had remembered to occlude. Unfortunately, her emotional state had rendered her more vulnerable to powerful nightmares.

She was barely ten when she met that girl, Elaine in Diagon Alley. She'd been purchasing her school uniform when she'd accidentally brushed the girl's hand with her own and experimented her first bout of empathy. Viewing those images had been traumatic and she'd screamed, weeped and fought when her father had taken her in his arms, persuaded that he was one of the masked men.

Finally, completely taken aback by her reaction, her parents had brought her to St Mungo's and she'd been diagnosed with a level 5 empathic ability. She was going to be one of those rare people that muggles feared and wrongly called mediums. Among wizards though, that trait was considered a real gift : empathy. Ever since she'd touched Elaine's hand, she'd been able to grasp and alter people's feelings and emotions, sometimes even thoughts and memories when they were strong enough. It had changed her forever and her parents too. It was a curse as well as a blessing and she had tried to escape it, until now, unknowingly drawing closer to her fate.

Very early on, Spencer had made her promise that she would never use it on him knowingly and she'd accepted happily. But last night she had broken that promise and she didn't know where he was right now. He had probably prefered to sleep in the Behavior analysis unit's headquarters, too angry at her to spend the night in her vicinity. She felt guilty suddenly.

At first, Reid had been angry without her being the cause of it. She'd been crying because her ex-boyfriend of seven months had cheated on her and she'd discovered it now that it was over, after she had brought herself to apologise several times for not being able to let go completely and trust him. When she had gotten home she'd been a wreck and had not been able to stop herself when she had seen her best friend so angry. She'd extended her hand and touched his arm, opening herself to his emotional state to find something, anything that would take her mind off the hurt.

Five minutes later, she had met his furious and horrified gaze with her wet one and he had brushed her off violently before storming out of the house. She had cried and cried again but she had not seen him since.

Aaron Hotchner was having a bad day. A serial killer was murdering prostitutes in the ministry's vicinity, leaving their mutilated bodies to rot in the streets, hair cut off, and torso showing multiple wounds that had been made by a carving curse. Thankfully, the Ministry of Magic now disposed of its own version of the muggle Internet, called the Source and Penelope Garcia their magical analyst had been able to identify them fairly quickly. The plot had thickened though, when the BAU youngest member, the doctor Spencer Reid had been accosted in the muggle tube by a teenager who could very well have been their unknown wizard.

And now, two of his team members the trustworthy Auror Morgan and the freshly debarqued Auror Prentiss were going from brothels to brothels, looking for potential witnesses, while Reid and Garcia were using the Source to find their missing suspect. Auror Jason Gideon, one of the founders of the behavioral analysis unit and the team's former chief was nowhere to be found. That was why, Hotch found himself greeting Hestia Jones, one of minister Shacklebolt's right-hands and tried to make her understand that in spite of her need for discretion about this case, he couldn't put the lives of women in danger just so she could show the wizarding world that the Minister's decision to appoint 25 years old Harry Potter, Head of the Auror Office had contributed to decrease violence during the last year.

« I do understand your meaning, Auror Hotchner, and I am not asking you to back down. Work your case. Find your wizard killer. Just do it quietly. »

« And if I don't ? », asked Hotch.

« I guarantee you won't work it at all », she replied as she stood to go on her way. « Oh and a little unsollicited advice : You're driven. You're bright. You're exactly the kind of person who could run the Department of magical Law Enforcement someday. You might as well accept now, that leading the Office has as much to do with politics as it does with law enforcement. Good day. »

And she left without a backward glance, stopping only to greet Prentiss on her way out, leading Aaron to think that perhaps Emily Prentiss had been sent here to acess him and not the other way around. Well, he'd be damned before he let that happen, he thought.

Department for the Regulation and control of magical creatures – MoM - Whitehall – Level 4

Artémée Wildbird was reviewing a file when Hermione Granger walked in, closely followed by...

« Gideon ! », she exclaimed smiling. « Is something wrong ? Spencer... »

«Is alright», he told her quietly. « I came here on behalf of Hestia Jones and Erin Strauss. They want the BAU to work a sensitive case quietly and I think we will need your talents. Would you mind working with us ? »

« The BAU ? But I am no perfectly trained auror... », asked Artémée, astonished. She knew that only the best wizards could hope to work among Aaron Hotchner's unit. It wasn't that the BAU was especially selective but the Behavior analysis unit was answerable to both the British department of magical law enforcement and the United Nations international department of magical fight against crime, which meant they had to report their achievements to high profile governors and couldn't afford to be anything but the best at what they did.

« You're an empath Artémée.', retorted Gideon soothingly. « And you've been trained to read and control emotions since you were a child. We will need you to assess people, not arrest them. »

« Furthermore », added a smiling Hermione, « Hestia especially asked for you because she knows I value your work here greatly. I gave her permission to appoint you consultant on this case and I hope they will recognise your gift for what it is. You are too precious an element to be locked away in an office. »

« Alright then. », she smiled timidely, grabbing her coat and bag. « Let's go chase that crazy temptress, adventure ! », she added for Gideon's benefit only. Perhaps working for the BAU would help mend her friendship with Spencer...

Behavioral analysis unit Headquarters – MoM - Wizarding LONDON – Level 10

An hour later, Gideon was showing up in the conference room, a young woman in tow.

« Aaron, allow me to introduce you to Miss Artémée Wildbird. », he said smiling and Aaron cursed invardly. That girl was the daughter of the late Jeremiah Wildbird, Gideon's best friend and Hermione Granger's protégée. If something happened to her while they were working the case, the team would be doomed. To make matters worse, she was often cited in the Daily Prophet as the century's best empath . They really didn't need the publicity.

Nevertheless, he extended his hand and met her warm, chocolate gaze with a welcoming one.

« I'm pleased to meet you, sir », the girl said while she shook his hand and he noticed the chill that traveled along the lines of his palm when she removed her fingers. The contact had been strangely familiar. His magic was humming in his veins and he cleared his throat.

« Artémée, here, is an empath and I thought she could help us with the case. »

« Aren't you a bit young ? », asked Hotch, meeting her honest, brown eyes once more.

« I turned 20 in October », she replied calmly. « I've had the gift since childhood and huh...I've been trained by the best masters in Occlumency. Hestia Jones personally approved my working on this case with you. As a consultant », she added, playing with the hem of her green dress, displaying nervosity for the first time.

« Alright then. As long as you follow my orders you are welcome in this team », he said, and the smile she offered him in return was nearly enough to reassure him.

Five minutes later, they were joined in the conference room by the other members of the team. Auror Prentiss greeted Artémée with a smile and a little bow, has per the pureblood tradition and Artémée replied with the same gesture, recognizing the status of the woman in front of her.

Of the two other women, she knew exactly which one was JJ and which one was Penelope. The former was blonde and thin, a classic beauty with kind, blue eyes, while the latter wore her personality on display, all bouncy curls and colorful outfit. They greeted her warmly and waited for the boys to do the same before they settled down.

Morgan, a tall brown skinned and handsome looking auror, greeted her with a grunt, his anger assaulting Artémée's senses and she winced, shutting down her empathy. Taking a deep breath, she turned away from him and met Reid's gaze with her own fearful one. She needn't have worried. Smiling sheepishly, he stepped forward and hugged her tight, blushing when they parted. Stuttering slightly, he explained to the team that Artémée was his friend and roommate and that they'd known each other for some time now.

Finally, they all took place around the table while Hotch, displayed the pictures of the victims on the black board. Frozen, Artémée realised that she had not been quite prepared for the sight of two unmoving, dead prostitutes in a wizard, moving picture. This, was unsettling to say the least.

« This », said Hotchner, pointing at the first picture with his wand, « is our unwiz's first victim. He held his urges in check for three months and when he couldn't control himself anymore he left this message for the aurors. We know the help and the hesitation marks he left with the carving spell means he was ambivalent about the kill but we don't know why he chopped their hair ».

« He didn't take any of it with him so we know it wasn't a trophy », stated Morgan.

« That's probably a way to minimize some of their power, he strips them of their femininity. »

« It fits that he kills them in the early morning, it's the time when the prostitutes have the least power sexually », added Reid.

« I know we're just spit bowling here », cut Emily , « but this profile points to Nathan Harris ».

« I don't want to talk about Nathan Harris », said Hotch firmly as Artémée looked at a suddenly tense Spencer. He seemed to have been personally challenged by Emily's comment.

« Hotch, she's right », replied Morgan, « he reached out for help. This is a teenager, he's probably intimidated sexually. I don't care how many time he said he didn't do it he knew about the last victim and admitted to getting off on seeing her dead ».

« We've got Nathan Harris, he doesn't do us any good at all to talk about him now, I just want to make sure that if it's not him we stay on top of our game before the Unwiz takes another life ».

« Alright », said Gideon while Artémée placed her palms on the wood, using the table everyone was sitting around as a vessel to soothe the tension in the room. « We know our Unwiz is a sexual sadist. »

« The symbolism of stabbing and carving with his wand probably means he's impotent ».

« The only way he can get off is by killing ».

« Considering that cutting their hair and killing them in the early morning comes from his feeling powerless, there's a chance his pathology is more than sexual », Reid added.

« What do you mean », asked JJ.

« It's London. Power is the more important comodity here, maybe this guy's feeling impotent in his professional life as well. »

« But why these particular women ? », asked Morgan.

« Because he's got access to them ? », Artémée spoke up without thinking, earning a glare from him.

« She's right, And he probably works in the vicinity too. »

« Well, we will go back down on the streets see if some of these women know someone who fits the description », Prentiss said.

« Good. », said Hotch. « It's late, let's go home. »

« Shouldn't we get a word out to the papers ?, »asked JJ.

« Not yet. »

« Well, it's not too late to make the morning edition », she countered.

« I said no. », he stated, his voice firm as he left the room.

« Sir ! », called Artémée, following him. « Would it bother you if I were to look at a memory of Nathan Harris's interogation ? »

« Would it help ? » He seemed tired and Artémée wondered if her presence didn't make things harder for him.

« Yes », she replied nervously. « Even if the memory is biased I'll be able to feel some of Nathan's inner emotions ».

« Then I'll make sure you have access to one of our pensives in the morning », he promised.

« Thank you ! Good night, sir », she said leaving.

She was the first to arrive the following morning and she noticed that auror Hotchner had kept his word. The pensive was waiting for her in the conference room and she wasted no time. Stirring the fluid with her wand she plundged and viewed the memory. When she stepped out of it, she was glad, she had done it alone since she was violently shivering. She had felt Nathan Harris's fear and disgust with himself and she figured she would have to tell her superior of her conclusion.

« You watched it », said someone behind her and she quickly turned around to face the intruder. It was Spencer.

« I did », she replied still shivering.

« Did he lie » ? The tone of his voice was anxious and Artémée once more noted the strange connection he felt with Nathan.

« No », she said. « He was afraid, self despising and completely honest I'm afraid ».

« What will happen now ? »

« I've not been doing this long enough to answer that question », she stated softly, « but it would be better to allow him to be tranfered to St Mungo. He could be safe there if not treated... »

« And if his mother doesn't allow it ? »

« Then we can only pray that he will be able to surpass his urges. If that is not the case then I fear you will have to hunt him down one day, when he'll begin to kill. Or, he could commit suicide. »

« I...huh... », Reid begun but his spellphone cut him off with a buzz. « Yes Hotch ? »

« We have another body. I need you to find Gideon. »

« Okay. » He looked at Artémée. « I huh...I have to go there's another body. You...I am...sorry, for the way I... »

« It's alright», she smiled, watching him go.

Nathan was innocent, but Reid insisted that he had a right to know what was happening so they followed through with his psychological evaluation. Gideon listened to him while he explained what happened in his mind when he fantazised about hurting woman and then, Artémée used her empathy on him, her hands cold against his forehead while he kept his mind open to legilimency. Shivering she watched his fantasies unfurl in front of her eyes while she analysed his emotions. When she was done, she let him go with a shudder and smiled softly at him, reassuring. Then they let him go and his mother came in the room where they tried to convince her of the necessity to hospitalise him, to no avail.

« What do you think ? », asked Reid when she got out.

« He is a psychopath », she replied grimly, her tone conveying her sadness. « And she doesn't want to let him go to St Mungo's. »

« What's going to happen now ? »

« She'll try to have him treated and followed by some specialists and you'll have to catch him when he begins to kill. »

« When he begins ? », he asked with something akin to despair.

The case was taking its toll on Aaron and he wanted nothing else than go home to his beautiful wife but they still had a sick wizard to catch. Pinching the bridge of his nose, he looked up to watch Artémée Wildbird interact with his team. It was obvious that she was familiar with both Gideon and Reid; she smiled at them without reserve and her posture was less guarded when they were nearby. With Prentiss and Jareau she was timid, surely because of the difference between their ages. She and Prentiss seemed amicable with each other though. After all they came from the same social circle, and pureblood families even years after Voldemort downfall, stayed close to each other, often partaking in political and charity galas to forget that they were still closely watched by the new government. Garcia was sweet on her, he could tell, because they sometimes shared smiles when they met each other's eyes. The analyst seemed excited to meet their friend's best friend and willing to befriend her too.

Reid's behaviour was telling though, even if he was always a little awkward around his female friends. His back and neck were tense when he spoke to her, and his hand was in front of his mouth more often than not, as if he tried to keep a secret. Yet his feet and entire body were turned toward her and it did not take long for Aaron to realise that Reid was smitten with her, as any healthy young wizard should, he reflected, noticing the beauty of her pale features who where enhanced by the fire in her dark auburn hair and the green of her dress. She was small, and feminine, curvacious and soft unlike the women Reid usually showed an interest in.

She kept away from Morgan though, unwilling to trigger his frustration. It was obvious she was afraid of him, probably because he was loud and hostile and she had already experienced violence in men she had known in her past. Given how young she was he'd say her father or someone in her close proximity. She didn't let the young man get away with it however. When he tried to get a response out of her she focused her gaze on him, fierce and unwavering and the otherwise impressive man always dropped his eyes first, grumbling as Reid frowned at him with disapproval. It was all quite entertaining.

Unfortunately as funny as it was to see them all interact, Hotch still had work to do and he got back to it with a frown. They had to catch their unwiz, before he could use another carving spell.

As the night went by without them getting closer on their killer, Artémée felt the tension raise among them. Morgan was shorter with everyone while Reid stopped talking altogether and Hotch and Prentiss pratically growled at each other. Sharing a worried glance with JJ, the young woman raised her hand discreetly and slightly tampered with everyone's emotions, letting go of her breath when the others relaxed. She shouldn't have...

Two hours later, they were examining another body and Nathan Harris had disappeared.

« He's certainly getting bolder », said Morgan.

« If it's the same killer », replied Gideon while Artémée was trying to catch her breath. The suffering here had left its mark in the atmosphere and her senses had caught it head on.

« You mean Nathan ? »

« Here », whispered Hotch, « Touch my hand, it will help ».

She did and she relaxed when she found nothing but sympathy in his touch.

« Thank you », she exhaled and he nodded.

« Officers », called one of the auror, « we found the boy you're looking for ».

Nathan was brought into custody but Gideon knew he hadn't done it. Instead, he encouraged everyone to go back and work on the profile. Breathing deeply, Artémée braced herself for a very long night and entered the conference room.

« The first victim gave him a taste of what it was to kill », Hotch said grimly. « The second he asked the Aurors to help stop him, by the third he felt like we had failed him and he was already devolving. The fourth, no ritual, no message, just brutal murder ».

« It's true that he's devolving but his last victim definitely held a message. You don't discard a body in front of the Ministry by accident », Gideon stated.

« Particularly when one of Shacklebolt's right-hand is about to pronounce a speech highlighting the decrease in violence since Harry Potter has been appointed Head Auror. », added Prentiss.

« But...that press conference hasn't been announced yet. Only someone from the inside could have known about it. », said JJ.

« We profiled that the unsub felt limited in his job. What's more powerless than being a big player on the Ministry's stage ? », stated Reid.

« If he felt like he did his part in cleaning the streets of the prostitutes but was never heard, he might have felt personally betrayed and litteraly had to carve his frustration onto these women. »

« So the profile was right we were just wrong about who the messages were for ».

« We'll need a list of all the people who worked on this project », Gideon said.

« Prentiss when you went back to talk to the prostitutes did the profile ring a bell with any of them ? »

« A few of them described what could be the same man».

« Let's go back to them. We're going to need their help. »

« What are you thinking about Hotch ? »,asked Morgan.

« I need to get a message to deputy Jones », replied Hotch smiling.

« How quickly can we put up a press conference ? »

« How fast do you need it ? « , smiled JJ.

Artémée smiled when she saw the front page of the Daily Prophet the following morning.

« Hotch certainly could have attempted a career as a model don't you think ? », Penelope whispered excitedly when she saw her waiting in the conference room while everyone else was working with the prostitutes.

« You're right, he's handsome», laughed Artémée, the merry sound turning into a choking one when she spotted Hotch behind Penelope. « Sir ! », she exclaimed invardly cursing herself for her stupidity.

« We found him », he announced frowning but not looking particularly angry. « I thought you'd like to join us ».

« Indeed. I mean yes sir ! », she stuttered getting up.

They hunted down Ronald Weemes and found him looking for his next victim. Hotch and Prentiss caught him while Artémée tried to reassure his sobbing wife. She had known nothing of his former activities as a death eater and his wish to get back at the man who'd killed his master and refused to notice his worth. Finally the case seemed over.

Unfortunately, Nathan commited suicide the following night. Full of despair, he nearly bled to death in front of a prostitute who called the only aurors left in the BAU and when Reid and Garcia arrived and made sure he'd stay alive, he begged them not to do it, to let him die.

Artémée had immediately been called into auror Hotchner's office, to use her powers on the boy's mother who had been in hysterics. Then she had gone to Penelope and hugged her, letting her empathy take away most of her pain while the other woman cried her eyes out. It had been easier with Spencer since she knew how to relieve him of the pain. The guilt would stay, though, she told Gideon and they should make sure to follow Nathan Harris closely, if they didn't want to lose Spencer too when the boy would start to kill.

Artémée looked at Aaron Hotchner then and she nodded, grabbing her cape, relieved to know that only a ride with the Magicobus was separating her from her bed. All of her energy had been drained and she didn't trust herself with an apparition.

« It's been a pleasure working with you, sir », she said as she was about to leave his office.

« I noticed what you did the other day », replied Hotch, sitting down in his armchair. « When you tampered with our emotions to get us to focus. I wanted you to know that I appreciated that. You've done a good job working with us. Thank you. »

« Anytime », she replied smiling.
