Now that you are older, twelve years and on the cusp of turning thirteen to be exact, your hair has started growing out and past your shoulders. He has had you speeding through school, after weeks and months of study sessions, but only on things that are useful. You do not need to write analysis assignments on preselected books or plays written in old English that kids can barely understand. Why do human school systems even make children do that? There are much better alternatives to get them to develop their writing skills. His teaching methods are far superior than humans' outdated teaching systems geared toward becoming factory workers. He swears that they are deliberately just trying to waste his time.
You skipped a couple grades, because it would be suspicious if you skipped too many, you would be put under the spotlight if you did, they only let young children skip so many grades at a time, and you are not mentally developed enough to learn that much. Do not get him wrong, you are great at strategy and artistic fields, but you are poorly-versed with math and analytics. Not that you need to know them very well just yet, but he would rather work with someone who has the attention span for things like that. You do not complain about studying on other subjects that much, but you hate trigonometry or anything that has to do with memorizing formulas, and you especially hate chemistry. Though, you do love biology.
He is decently content with your progress so far, predicting that you will graduate school at sixteen years old at most,
but something spooked him when you were around three years of age.
When you were being taught shapes, he stuck around and watched you for a bit, since there was nothing better to do. When you got to learning the triangle, the tutor showed you a wooden blocked shaped into an isosceles triangle. When she tried to get you to associate the name with the shape, you looked over to him, then back at the block.
Then, that was when you squinted at him and pointed, yelling "triangle" at him.
His mouth hung open at that moment, he was sure. How did you know that? He has always been stuck in this human body, so you never got the chance to look at his actual form, nor did he say anything about himself or his little cult - not that you would understand him anyway. There were no depictions of him, no tapestries, and nothing else of the sort that could have even remotely clued you in about him. Even if you saw depictions of him, you would not be able to connect the dots.
That was when he started keeping a closer eye on you. You had a field day after you realized he was starting to follow you around and pay more attention to you. Usually, he would be annoyed by something like this, but it had him smirking that you enjoyed his presence that much. People only like him hanging around them after he has charmed them, but you liked him since day one - literally. It either could have something to do with your eyes, the fact that you are twins (well, twins with his vessel), or a little bit of both.
Now that you are able to hold conversations with him, he finally thinks it is about time that he figures out how you know about his original form.
You are sitting at the old desk with the older computer that people do not really like to use, as it does not run that fast and cannot play video games on it. The desk is made out of a semi-basic wood and has marks on it from the beatings it has taken from children over the years, and has old gum wads stuck under the battered piece of furniture. The desk chair you sit in is squeaky and hard to the touch, as the thread-count for it is cheap and course, but it still has some life left in it to live before it has to be replaced.
The desk is situated in one of the girls' bedrooms, the one that you sleep in along with an older girl who is at the end of her junior year in high school and two other girls who are in their freshman and sophomore years. The beds are just big enough for an adult to fit in, but not very spacious in general. You only have so much growing left, so pretty soon that bed will feel small for you just like it does for that other girl who often used to complain about it once she got a few years past puberty and went into her growing phase.
