So I made the New Year's resolution to do a fan fic challenge. Now it's March. Better late than never.

The one-shots will focus on Gon and Killua, not specifically Gon/Killua. I'll be trying to get different takes on the relationship as well as their personalities in general, so expect more friendship bordering on the edge as opposed to outright romance (though it will be there).

All prompts will be taken from the Psychological Fanfic Challenge on livejournal, so you can guess most of these won't exactly be rainbows and unicorns, but they won't be outright angst either. Any warnings such as spoilers and the place the story is in canon will be mentioned to avoid any misunderstandings. Spoilers will be marked for anything passed the Greed Island arc. Please keep this in mind for future stories.

I hope you enjoy.

Things to know: Set in different points of the canon universe

Skinner Box
A cage designed for animals in operant conditioning experiments. This was developed by B. F. Skinner, considered to be the father of behavioral therapy. He once stated that with the ability to control a child's environment, he could raise a child to become anything he wanted.

No "pure" food. Everything is to have at least two milligrams of poison added, but never use the same poison twice in the same week. He should be able to handle three grams of any deadly or paralytic poison by his first birthday and triple that by his second. Any liquids are to be spiked as well, even Kikyo's milk.

When he's older, his food should stretch across classes and cultures of every kind, swaying from one extreme to the next. Give him the finest cuisine in Azine followed by the cheapest slop in Yorbian, randomly dosing them with tasteless poison. If he ever hesitates, have needles standing by with double the amount of poison in the food to jab into his arm for punishment, just under the dosage needed to kill him. There should at least be enough to make the experience painful.

The only food that won't be poisoned is what he can sneak passed without anyone knowing. If he goes into the kitchen, don't let him see the workers add the dose. Food can be left untouched if he manages to keep them under surveillance. He needs to be taught to be suspicious of everything given to him.

Killua barely reacts when Gon enters the hotel room, mind completely focused on the game in front of him (one more level till the boss). When half a bar of chocolate is waved in front of his face, it's impossible for it not to capture his attention. It's not so much that he really wants the chocolate but that the light shining from his game keeps bouncing off the wrapper and practically blinding him each time Gon's hand shifts even the slightest millimeter. His character's dead within seconds.

"Do you want the rest?"

Killua considers Gon's carefree smile. There is no proof the food is safe. He has neither seen Gon purchase or eat it, and there were endless opportunities he had to alter it on the way from the store to the hotel. The sheer amount of drugs needed to incapacitate Killua isn't as hard to get as some people would like to think (for a Pro Hunter at least), but the thought never crosses Killua's mind. He shoves the whole thing in his mouth without an ounce of hesitation, muttering a thank you as Gon takes the seat next to him.

Electrocution every day: 100 watts for ten continuous minutes. He should be flinching every time the lights turn on during the first few days. Once the nervous tick disappears, double the time to twenty. Gradually increase the time by ten minutes each week until the battery becomes exhausted from overuse. After that, focus on the amount of watts. Double the intensity every week whether the nervous tick is gone or not.

Give him opportunities to run once in awhile, but don't make it obvious. Only let him go if he can escape using his own skill; never go easy on him. It's okay to injure him, but it can't interfere with his other training. If you do catch him, it's another twenty minutes. By the time he's five, we want him to never recoil from any kind of shock. Be it from small sting of static on his fingers or a 1,000,000 watts, nothing should faze him. Anything that does should be avoided at all costs.

It's around the fifth month mark of knowing Nen that Killua first feels the side-effect. If he had to describe it, he'd say it was tingling sensation, but he still isn't sure if it can be called painful. After a few more incidences where he uses his electricity technique, the feeling graduates to a shock, ripping through his body and setting every nerve on high alert for the next wave of static every time his Nen brushes someones else's. What's even weirder is that it actually stings him enough to get a reaction, falling soundly into the painful category.

On a not completely separate note, Gon becomes very confused when Killua starts flinching the slightest bit each time their hands brush as they walk, never feeling the same sensation of being tasered like Killua. He watches Killua's hand move, almost like he's going to take Gon's hand, before falling back to his side. Gon holds out his hand for Killua to take. It's a simple invitation his friend can easily refuse, so he has no idea why Killua recoils so sharply when he accepts it. His hand stays in Gon's, though, for the rest of the way home.

Never give him a hug. If you do, make sure to hurt him at the same time. There's no reason for a kiss of any kind, even if you're checking for a fever. There are thermometers. The most his family can do is tell him they love him while watching him spasm through the poison, and even then they must make sure their voices doesn't have too much warmth. Illumi already shows problems with this, but his wrapped way of thinking seems to be okay. In fact, it looks to be speeding up the process nicely. If things continue this way, it shouldn't be too hard to convince him to insert one of his needles. Just a small one as a safety net.

Take any opportunity to mislead him. Betray his trust until he stops telling you secrets. To put it bluntly, no affection in any shape or form. He should depend on no one but himself. Relationships that involve trust and affection should be the farthest thing from his mind.

Waking up with his head nestled into Gon's shoulder should have surprised Killua more than it does, but then he's a little more preoccupied with his completely numb arm pinned beneath his friend. The safe feeling in his gut is a bit concerning too, but that's a thought for a later, more reasonable time like noon.

Yesterday had been one insane chase, Killua eating Gon's dirt as he ran from one end of York Shin to the other in an effort to see it all before they got down to business. Killua hadn't known where they were half the time, relying on Gon to lead the way, but he'd had the sinking suspicion Gon had been lost about fifty percent of the time. He followed anyway. It wasn't like Gon is some idiot that would lead them into an alleyway to be attacked. He knew Gon knew what he was doing...to some extent.

By the time they got back to the hotel, both had flopped onto the nearest bed without a second thought. They'd been on completely different sides of the bed and facing a different way. How the hell they'd managed to end up as tangled as they were was beyond the half-wake Killua, but he wasn't complaining. It was actually comfortable in it's own strange way. Warm enough that he easily fell back into his peaceful asleep at least.

Killua shows signs of resisting training, but it's nothing that can't be stomped out.

It took no time for Gon to tear down every lesson Killua had been taught and turn it on its head.
