I've only read the first book of CLC, and that was /ages/ ago. So, given I know my knowledge is rusty, I'm going to do something a little abstract. :P Enjoy!
Day 17: Chronicles
In order to believably possess Eva Skinner, XANA would have to bypass some of the things he'd been more curious about when it came to being human.
More often than not, whenever he took a human body, he only had a few simple goals in mind. Catch the kids. Chase the kids. Kill the kids. Go back to living without a body and forget what it was like to have a body at all. But that was only workable back when he could abandon a body. Back when he had the supercomputer to retreat to.
Now he only had Eva. And in order to keep Eva alive he'd had to figure out things like eating, and sleeping, and brushing one's teeth, and speaking in coherent sentences. But those were hardly the things he was most interested in.
His first question - how do humans get their hair to grow backwards? He'd seen the Lyoko Warriors' hair grow longer, then shorter, than longer again, over the course of many years. He'd had reason to believe human hair did get longer, but he wasn't sure how it got shorter. Eva Skinner's hair was short enough, so he wasn't sure he wanted to mess with that.
But it didn't stop him from staring in the bathroom mirror in the middle of the night, attempting to will the hair shorter. How DID they do it? He regretted not being able to instantly look it up.
And then there was this instinctual reaction to animals he'd developed. He'd almost never paid attention to them before, unless he needed them to do something for him. But now… whenever he passed a cat sleeping on a fence or a squirrel skittering around the Kadic forest, he felt the insatiable urge to pet it. He was never able to catch them for long, but the feeling of their fur was like nothing he ever thought he'd feel…
And of course he hated that he'd gotten caught up in that. Hair hardly mattered in the scope of his master scheme, and neither did fur for that matter. There would be no trace of any of the trappings of human or animal dominance once he'd claimed his victory. Not unless it was strictly subservient, or kept around for his own entertainment…
But it was a different kind of hate than the hate he'd had before. In the beginning his actions had been automatic, carried out against a force that was alien and terrifying to him. But now, he'd discovered some part of what he hated for himself. And he would like nothing better than to wipe it all off the face of the earth and remove himself from Eva's body, just so he would never have to confront the fact that he did.
