It was bothering me.

Admitting that on its own was bothering me as well.

I rewound the footage for the umpteenth time to try and discern the anomaly, but I was coming up short, and it was unnerving. My instinct never failed me and I refuse to acknowledge that it was doing so this time. I had narrowed down the possibilities to that these Zoldycks were too used to camouflaging what they did and I just needed time to see it, or that I was fatigued.

I do not accept either.

I have been trained – consciously and not – to see things like this, I will know what it is.

'Oh? Still looking at the footage?' I heard the clicking of his heels while he leisurely leaned himself back in the doorframe. I stopped the film after a couple of seconds when I noticed my focus wouldn't increase with Hisoka in the vicinity. 'Is it messing with you this much? Why not let Chrollo take a look at it.'

'Chrollo is working on finding out about the possibility of one of our staff having drugged Killua – although unlikely. I will find the anomaly, it's a matter of time.' When I looked up at him, he gave me a knowing grin and slitted his eyes a little, but that wasn't what caught my attention and I inclined my head a little. 'Is there a reason you're wrapped in Christmas lights?' Not only that, he had some sort of crown on his head, there seemed to be glitters on his clothes, and little bells around his neck.

'Surprise attack.' It was hardly a complete surprise if they had the chance to do all of this. He'd probably fallen asleep in his office earlier.

'Machi is talking to you again.' I guessed, looking back from his decorations to his eyes again. But it wasn't really a guess. Although she was composed most of the time, she won't hold back if she believes you've done something to her. Hisoka can't stay away from a temptation like that. He takes pride in pushing the buttons of others. However, no matter the retaliations against him, they have yet to find his button. I believe he is grateful that I am the only one holding that knowledge, and that I don't care.

'Talking isn't exactly how I'd call it.' He shrugged it off, and adjusted the crown on his head. 'These Zoldycks must be quite the masters of deceit if they've got you working on a single theory for more than two days.' I turned my eyes back to the screen, and heard him stepping away from the door, closing it behind him.

'My focus worsens with other persons in the room, you would be more appreciated at the other side of the door.' The light jingling sound didn't change directions though.

'You've been looking at that screen in all the free time you have. I know you're aware that it's more productive if you take a break now and again.' When he reached my desk, he decided to hop on it, and crossed his legs, leaning one glittery arm in between me and the screen. 'So why aren't you?'

'If you want to keep that arm, I suggest you remove it from my view.' I closed my eyes and noted this exasperatedly. Knowing that I was capable of such a feat, Hisoka moved his arm back a little.

'Is this one of the rare times your pride is getting in the way?' I lifted my hand to click the video back to the beginning,

'I don't have pride, I need to know what's going on here before Sunday.'

'Ah~, before the big questioning of our dear Il-lu-mi himself.' He pushed himself off my desk and stepped behind me, leaning his head next to mine. 'Are you afraid you will lose to Killua because he was brought up by the people that are keeping a secret from you in this video?'

'… …' I wanted to threaten him again, but he stepped away before I had the chance to. A soft chuckle escaped his throat, and he kept his position behind me.

'How are things going with Killua?'

'You can go see Nobunaga if you want small-talk.' He laughed a bit louder at that, and I paused the video again.

'I saw him earlier today, that's why I ask.' He got my attention with that, and I could feel his amusement behind me. 'Now I have your attention?' Nobunaga went to Hisoka for Killua and not me or Chrollo? That didn't sound right.

'Oh? But he didn't come to you? That surprises me.' I turned around in my chair and looked up at Hisoka leaning against the wall. Somehow those decorations on him didn't seem all out of place, for the extravagant person he is. 'I'll tell you about it if you come with me for some… distraction.'

'Whatever distraction you have in mind is completely self-serving. You know I can just contact Nobunaga for this information.' His grin grew and his eyes narrowed some more,

'I don't think he'll appreciate it at two in the morning.'

'I do not need to know at this instant, I will contact him when I have the time.' Hisoka laughed shortly, but I didn't understand what was so funny about my statement.

'Then for the three hours you have left before Killua's next session, I am ready and able to distract you in my office. I don't need to tell you that by fixating on this video, you won't be able to focus on him. If your pride really is killing you, then I suggest doing some damage control.' His tongue flicked out for a second before he stepped away from me and strutted towards the door again. I was weighing my options.

In general Hisoka would be correct, however I am able to keep focus for long periods of time and my judgment should not be impeded by a mere two days lack of sleep.

On the other hand, it has been a long time since I've been in a situation that required this much concentration, and it was clouding my view. No matter how much I wanted to train that out of my system at this very moment, I needed my full attention during these sessions with Killua.

I closed my eyes for a second when I decided my course of action. I will leave this video for what it is at the moment. I'll talk it over with Chrollo after the session.

'Well, sparring for an hour should do the trick.' I spoke up and turned off the computer. There would be no problem with some distraction if it was on my terms. The ringing of bells hanging around Hisoka's neck stopped when he turned around on his heel in the door opening.

'Ah~ that's music to my ears.' I stood up from my chair and got the bag with my training clothes out of one of the cabinets, leading the way to the court.

Dad had called me again on Wednesday. From now on, five minutes on the phone per day were permitted. However, that included received calls as well, and yesterday dad had taken up three days' worth of that. That meant less time contacting someone I actually wanted contact with at this point.

I leant my elbows down on my knees and raked my hands through my hair, dropping one back down to count off the days. Monday hadn't counted, Tuesday I'd reached Gon before my parents could reach me, and the Wednesday counted as Thursday and Friday as well. So the soonest I can reach Gon again will be two days from now.

I want to warn him of what I've been ordered to do again, but honestly I don't know how to deal with this. If I was able to hint it to him correctly and he would take countermeasures, my parents would know what I'd done and take matters into their own hands – giving him even less of a chance. I could warn him not to do anything but be wary of it until I knew how to deal with it, but that would be unfair. I'd only be worrying him. I need to figure out for myself first what I need to do to get out of this. God fucking damn it, I don't want to choose a side.

'Killua? You in there?' I snapped back and raised both my hands behind my head, leaning back in my chair and giving Nobunaga a look that spelled I really didn't care. Group session was Thursday this week, apparently. 'You're quiet today.'

'I'm always quiet, it's because I don't care about this group thing.' The man sighed loudly when I said this and his eyebrows drew together, ready to scold me again for my "lack of participation", when the man next to me drew my attention with his quiet voice,

'The idiot means you're differently quiet.'

'Oy!' The so-called leader of this group stomped his foot at that statement. I paid it no heed, 'cos Feitan was the only one more reclusive than I was, and him speaking up was actually quite rare. I turned my head and leaned it back against my hands some more, giving him some of my attention.

The only thing he did was look back at me as well for a while. This guy was also a martial artist, right? Illumi had mentioned him but I'd pushed it back after our fight. It's not like he stands out or anything. "Do you want to take my place in the Zoldyck family?" Is what Gon would immediately ask of him, and I huffed when I thought that it would probably be perfect, were it not that for the most part I like what I am able to do. I can't deny that the idea of this guy receiving my training made me slightly jealous. I lowered my eyebrows a little at that thought, before I asked,

'You're a good fighter, right? Want to train with me in the court?' His eyes were unchanging when he answered immediately.

'Hisoka needs to stop talking.'

'That a yes or a no?' Everyone around us had gone quiet. I let my eyes glide over them a second, and saw that this rarity was apparently way more important than the actual session.

'Sure.' I looked back when he answered, but he'd already turned his head away. If people thought I was quiet, than they apparently didn't know this guy.

'Oy, that's not really up to you guys.' Nobunaga spoke up again, and his words started irritating me,

'Why not? The court is an extension of the gym, isn't it? Why can't we spar?' I directed at him, but it was Feitan who spoke up again,

'I'm not allowed to fight, they're afraid I will kill you.' I scrunched my nose at him when he said that. They were sorely underestimating me, weren't they? Those little…

'And not ungrounded, I might add.'

'He was hardly on the verge of dying.'

'Going after your psychologist's life isn't exactly a small misdemeanor, Feitan, no matter how he walks away from the fight. I will discuss this with Illumi and Hisoka first, you two stay out of each other's hair in the meantime.' So he'd done that too? Interesting.

'Yes sir.' I raised my voice and mocked him with my sarcastic tone, sticking out my tongue when he hung his head and let out a deep breath.

The rest of the session neither of us had spoken up anymore. That little exchange had been exactly what I'd needed. If I spar with Feitan, there will be constant surveillance, but I could probably request for the cameras being turned off if our shrinks would supervise. Those guys seem to be more aware of my skills either way. I frowned when I thought about that. They'd perfectly deducted the nature of my relationships and probably knew exactly what I did for a living.

But I'm still here.

Is it because they only have circumstantial evidence, or did they actually mean it when they said they're not interested in sending me to prison? Up until now they've been quite frank in their actions, even told me all their findings about me. That will give me an edge on them, why did they do that? It could mean they really aren't interested in what I do, but those guys are way too fucking unpredictable to assume anything. I'll just focus on the questions I'm gonna ask Sunday.

'Killua,' I turned my head back to Feitan when he spoke up softly while Nobunaga was in conversation with someone else. I dropped my arms and leaned them down on my knees, perking my ears.

'Can you fight without wanting to kill?'

'No.' I lowered the volume on my voice to the extent only someone like Feitan would be able to hear.

'Then I suggest you fight with someone else.'

'Why.'

'I would enjoy killing you.'

'I hope you're not underestimating me.'

'You should be able to see the difference in our strength.'

'Don't patronize me.'

'I should say that to you.' He's suggesting he'd be able to kill me if I came at him with killing intent. I can see that he's strong, but the difference he's talking about…

'If we get permission, we will fight.'

'… …' He didn't respond any more after that, and Nobunaga showed no signs that he noticed our conversation. I got up and out of the room first after the hour was up, and stopped just outside, watching Feitan walking away in another direction. What kind of world did he come from that he was like this?

'I highly suggest you retract your request.' Nobunaga stopped behind me, but I didn't stop looking at Feitan until he was out of sight. 'Although Hisoka gets very close to the why and how Feitan is like this, changing him seems to be out of the question. What he's doing now, is keeping him away from fighting so his muscles will forget how.'

'Then there's no problem filing the request, is there? Hisoka will just refuse and that will be that.' I sounded a bit too smug when I said that, and Nobunaga patted me on the shoulder before passing me and walking away.

'Go to Illumi if you want to fight, I'm not requesting anything for you.'

'La~me.' I called after him. If I ever want to test myself against Feitan, it will have to be off the records then. I can do that if I want to. Gon, next time you're here, we're sparring again.

'I suggest you get rid of some of your ornaments if we're going to do this.' I heard the redhead's laugh behind me,

'I won't change until I'm at the court, I have been threatened that if she sees me without it, my house will be next.'

'That is an expensive payback, what did you do to Machi this time?'

'Nothing out of the ordinary.'

'Nothing is ordinary with you, don't lie.' Hisoka's amusement grew once more, but he refrained from saying the obvious that I was not ordinary either. I have never claimed to be,

'If you want the truth, you should ask her.'

'You know I won't.' This wasn't worth devoting time to. I will notice if it inconveniences me.

I opened the door to the gym – it was supposed to be locked at this hour – and found my way directly to the court, dropping the bag next to me as soon as I entered there.

'Hisoka.'

'Hm? Yes?'

'… … What?' I looked at the unusual scene before me, and it was the only question that came to mind.

'Isn't it obvious?'

'That is exactly why.'

'Do you want me to tell you why Nobunaga came by earlier?'

'Don't tell me he has anything to do with these decorations as well. What have you done to him?' When I turned around to him, he was already starting to unwrap himself, it seemed Machi had done a good job tying him in.

It was when I turned his way though, that I noticed Killua standing against the wall behind him. I cocked my head,

'Why are you here?'

'Not to spar with Feitan.' He scoffed and turned his head away, pocketing his hands.

'You promised him this?' I turned back to Hisoka, but he was consciously ignoring me, only giving attention to untangling himself. Killua raised his volume some more,

'He promised me some physical activity. Oh well, shouldn't have expected you guys to listen.' A pout appeared on his face. He knows we listen, he starting to understand his position in all of this and that he has several privileges he shouldn't take for granted. He's becoming careful not to do something that will revoke those.

I looked back at Hisoka, and decided to pull out the last knot Machi had put in there so he would answer.

'What were you planning on doing with him, Hisoka?' He took the crown off his head and smiled at me,

'Not what you're thinking of, dear Illumi.' I saw Killua's eyes shift towards us when he heard that answer. 'Nobunaga suggested one of two things to me when he approached me.' He lifted his hand and raised one finger, 'Either I allow Feitan to fight just this once, which is never going to happen.' He waved his finger a little, and I saw Killua's scowl when he stated this again. 'Or….' He raised a second finger, 'I would spar with him myself. Because apparently someone wants to let go of some stress.'

'Then why am I here.' Killua turned his head away at that point.

'Oh~, but I was dearly rejected as a sparring partner.' He paused for a second before finishing his sentence, his lips raising into a grin, '…How's your arm doing.' I turned my eyes back to the boy and inclined my head,

'You requested to fight me again? What do you hope to gain from that?' Was he really that desperate for physical activity that he would risk it once again? This time I wouldn't underestimate him. 'Do you hope to learn more about me while doing this?' There was an elongated silence, 'You're going about it wrong if you hope to find out anything, it's best if you just wait 'till Sunday if that's your goal.' I threw my arms wide and tilted my head back a little. His first choice had been Feitan though, so perhaps it had nothing to do with me. Even so, he probably saw this as an opportunity.

I lowered my arms and lay them on my hips, but his eyes weren't on me,

'Can we shut down the blinking "I know where you live Hisoka" sign first and turn on some normal lights? It's fucking annoying.' I tilted my head towards the man that had instigated this decoration, and he raised his hands in innocence as he turned around and put the main light on first. 'Where did you learn to fight?' The boy didn't look away from the sign when he asked,

'Why would that interest you? You have your own style as it is, incorporating mine is-'

'I want to learn it.' His eyes shifted towards mine, and I raised one hand palm up to make my point more clear.

'That's impossible, it's nowhere near the abilities you have now.' On top of that, this boy doesn't need to learn any more fighting skills. I am absolutely certain they will be used for murder, and I won't teach him until he admits this. 'Why should I teach you any more of the skills you used for the reason you're in here?'

'I'm not asking you to do that.'

'Then what are you asking of me?' He pushed himself away from the wall and stood square in front of me. Meanwhile, the blinking sign had stopped blinking. I know that what I'll teach him is not something he'll be able to use while doing what his parents taught him, but if this question could keep him at bay,

'… …' He fell silent, good.

'If you can't come up with a reason why I should, then I'm not wasting my time on this. I will do what I came here to do.' I turned my head towards where I heard Hisoka's footsteps. He just raised his hands and shook his head in rejection. I cocked an eyebrow when he did this. He never intended to do this, did he. He wanted me to suggest another place than his office for distraction. 'It seems we were both misled by Hisoka. However, I'm still in need for a distraction. I turned my eyes back towards Killua. As long as it was battle, then there was no danger.

'I will fight you, but I will not teach you. But I am not unaware of your talent, so I won't show you anything I don't want you to see.' I inclined my body slowly towards him, and exuded the threat he's felt before. When it reached him his eyes widened for a split second, but he composed himself quickly afterwards. His eyes betrayed that he was still scared, but he was still confronting me. What kind of resolution had he gotten in these past four days? Did it come from his parents, or did it come from Gon? 'Or should I just leave now?' I pointed my thumb towards the door to my left, at which Killua nearly started to growl.

'I'm not accepting charity. You will teach me because otherwise I will find a way to fight Feitan.' He turned his head sharply towards Hisoka.

'Don't be so naïve, I will not be threatened into teaching you.' I intensified the feeling of fear inside of him, and his eyes opened a bit more, staying in that position. Hisoka on the other hand, was enjoying the feeling. If this would continue too long, I would have trouble containing myself again… I reckoned Hisoka was looking forward to that.

'What would convince you?'

'Why should I indulge you in this?' I cocked my head at his question. It took him a bit longer to respond with this kind of attention on him,

'Because you still need distraction.'

'Ah, that's true.' I stopped exuding the fear, and waited for him to continue,

'And…'

###

I want to be able to stand up against my parents when they force me to go after Gon's dad again.

But I couldn't say it. I can't say it. At first sparring with Feitan had just seemed like a fun way to pass the time, but once I got the idea in my head that I could learn from this guy, it wouldn't leave me.

'And what?'

'… …'

'My suggestion still stands. I will spar with you, but I won't teach you anything until you give me a good reason why I should. As it stands now, I will just use this to pass the time in a way that it won't inconvenience me. If you're okay with that, then we can start.' I took a deep breath and closed my eyes for a second before looking back up at him, glad I was out of that feeling of his again,

'I am okay with that.' I will have to stop hiding what I can do if I really want to become stronger like this.

###

'Then I'll get dressed.' I slid the jacket off my arms and started unbuttoning my shirt, keeping note on Hisoka who walked past behind me.

'Is it alright if I watch this?' He leaned back against the wall and looked straight at me when I kicked off my shoes to change pants.

'We can also alternate.' Glancing back at Killua, who gave a slight nod. I didn't need his approval, but asking for it gave me a hint on the strength of his motivation. Hisoka lowered himself against the wall, and raised one leg to lean his arm on. Meanwhile, I opened my bag to get dressed again, and heard Killua throwing his shoes aside, walking silently to the middle of the room. He is more serious than before. A lot has changed since Monday.

After pulling the shirt over my head, I threw my hair back and tied it up so it wouldn't get in the way. I noticed the intensity of my focus as well. We are both more serious.

At the point where I stepped out in front of him, I noticed he got in an opposite mindset of mine. He's always quiet when it comes to moving around, but his steps just now and his breathing at this moment were inaudible. He'd made himself disappear completely, and in his eyes there was nothing left but focus. Have you stopped trying to hide your abilities?

In response to his mindset, I put myself aside and turned completely blank except for the need to fight. This, would be enough to send most walking away for their own good, but nothing changed in Killua.

Although it could only be the product of enduring harsh training from a very young age, I approved of it. Even without me holding back he'd be able to stand back up again and again. By now there was no question anymore that I'd have to ask Hisoka for a favor later on…

We stood no more than three feet apart, and I slid one of my legs back a little, loosely raising both my hands in front of my chest, inclining my body slightly. I watched him raise one hand soundlessly. It was a good way to fight, one sense of your opponent would be disabled. But it will take more than that for him to overpower me. I will teach him that then.

He was the first to move, he made a small feint to the right before lashing out with his right hand to my wrist; fingers stretched. I bent my hand and moved it down an inch, folding it back to push Killua's attack away before catching the opposite foot going for my knee with my lower leg. I slowed down the movements that had caught his attacks for a moment, before pushing them away with a force, and using the momentum to twirl around him and end up behind him; grabbing his shoulder with my right arm, and placing the tips of my toes against the inside of his ankle, pushing his leg away.

I wanted to turn further and grab his arm, but he wasn't caught off-balance, and turned around towards me, wanting to repeat my move on me. But I stopped the arm reaching around my waist and I turned him further with a force; he landed a ways behind me before I turned back to the right side myself.

All of this happened in a second, yet he had attempted to duplicate my movement. That had been impressive.

As a reward I decided to attack him this time, and took a big step to get close enough to do that. Unexpectedly, he didn't go for that opening, and stood still when I stretched out one arm towards his side. He evaded marginally, but I punished him for that by tightening my muscles to follow his movement, and he got the side of my fist in his side after all. He flinched lightly before lifting his opposite arm to throw a punch against my ear, but in the meantime my other leg had caught up and I brought my knee up in between us and pushed his arm away; turning my leg to lay flat and hook my foot in his side to force him away. He'd been just in time to catch me, but he had no choice to be thrown to the side this time.

He flipped back to recover. During these two short moves, I had barely heard any sound. That was impressive.

'If this is how you normally fight, then I-' I got interrupted when his fist aimed for my solar plexus, but I turned away without much consequence and placed the side of my hand against his neck to push him past me, lifting my last leg to sweep out the legs from under him and when he made the flip to recover, punched him down to the ground right before me. Usually I don't use a lot of force in sparring sessions, but I wouldn't let myself get interrupted by the useless eagerness of Killua. '—mah, I wanted to compliment you, but it seems there's still a lot of childishness in you. I could hear that last attack coming.' He huffed and looked up at me before lifting himself off the ground. There wasn't even anything he wanted to say. He was completely focused if he was just taking my words for granted.

'You're being too kind on him.' I heard Hisoka's voice in the distance.

'I appreciate you keeping quiet until it's your turn.' I heard a soft chuckle, but kept my focus on the boy in front of me. We were both going easy on each other at this point. This was a whole different fight than before, and neither of us knew the other's capabilities.

'Are we going to keep testing each other for a while, or should we stop holding back?' I lifted my hand with the back of it turned to him. Having long fingers, it was disadvantageous for me to attack with an open hand, and I could see this surprised Killua as well when I came at him. But instead of simply moving his head, he lifted his hand with his fingers split, and ready to catch me with it and continue the movement away from himself. However, I bent my fingers over before I hit him and snaked my hand around his defense, stretching my fingers again to hit him against the side of his head; but he caught the impact with his other hand, even though he was shoved to the side a little.

He stopped for a moment at that point, and straightened his back. He stretched his neck a little before looking back at me and did something to catch me off-guard.

The look in his eyes intensified, and his presence came out of hiding with bloodlust seeping out of him. I inclined my head when I noticed that at this very moment he was imitating the trick I learned by accident and did not completely understand.

This was bloodlust though, not killing intent. This was closer to what Hisoka would exude if he knew how. Killua was better at imitation than I had anticipated – he really had been holding back a lot of his talent.

I straightened my back completely as well, and stood ready to attack him again, but for once he beat me to it. He feinted to the left, to the right, he did this a couple of times to throw off my visual senses as well as my hearing. He kept this strange movement up all the way 'till he attacked me, and hit me full force against the arm he'd injured before. Fortunately I'd anticipated this move, and used muscle movement to spread the shockwave so it wouldn't be a hard hit. Before I got the chance to hit back, Killua had already removed himself from my range. He didn't stop exuding his bloodlust though, that was going to cost him his stamina.

'Have you noticed already?' I moved my fingers a bit and noticed that I'd spread the impact well enough to keep going.

'Your parents are correct in calling you a genius. You're still careless in your moves, but you make up a lot for that with your talent.' Once he's my age with this kind of talent and training, he will be able to beat me. Killua gave me a slight nod in acceptance of the compliment before falling back in his feints once again, only this time he used them to gain speed and get behind me. I couldn't follow his movements exactly, but my reflexes helped - at the moment of attack his movement changes slightly. So when he stretched out his hand I evaded, grabbed his wrist, circled one leg back to get him off his feet and spun him vertically over his own arm. I wanted to twist his arm when he landed, but he'd clawed out at me, and I let him go.

'But you have to remember that I have more experience in longer lasting fights.' At that point Killua stood with his knees far bent, and put his body to a complete standstill. Knowing what he was about to do, I brought myself in the same state and when he increased his speed to land an attack to my neck, I evaded differently. I bent through my knees completely and let my body bend backwards, lifting my palm to give him the punch he wanted to give me. But he grabbed my hand in time and only got part of the impact, throwing my arm aside. At the same time I lifted my leg to kick him, and got him with that one, making him back off once more. I continued the motion of my leg and spun it over so I would be facing him again.

'Your flaw is that you become predictable. You've been trained for one hit kills. You have a lot of tricks, but you don't last.' At this point Killua noticed that keeping up the bloodlust cost him precious energy and stopped it – reverting back to being completely soundless. 'Do you want me to show you how I fight?' He didn't nod, but his eyes told me that he was both wary and wanting of this. 'Then I'll slow down a little so you can try to copy.' I took a normal step towards him before lashing out my leg at his head. When he ducked down a little for it, I instantly changed the tension in my muscles to switch direction and hit him with full force on top of his shoulder. He managed to take some of the blow with his hand, but he made a sound.

Hisoka did as well.

'You're a cruel man, Illumi.' Killua flinched to the attack, but I was too late to notice the short moment of silence before he hit me with his speed again. I spread the energy of the impact out from my side before stepping away; but that had been quite a punch.

He wanted to continue his attack, but I twirled out of his way and kicked him to the side a bit before setting my leg back down.

'I'm only here to relieve some tension and Killua said he was okay with this. There's nothing cruel about it.'

'This is not your fight, keep out of it.' Hisoka turned his head towards the boy as well when he said this. I responded with respect,

'It's good to see this dedication in you. I will not hold back anymore.'

A/N

I AM SORRY I HOPE THE FIGHTSCENE IS SLIGHTLY READABLE I'M A LOVER NOT A FIGHTER

But aahhh~ Hisoka wrapped in Christmassy goodness...~
It's winter over there, I couldn't resist :3

I don't exactly know yet what kind of role Feitan will be playing in the future, but I don't do character introductions for nothing, don't worry.
Each and everyone that talks with either Illumi or Killua has a role to play.
