so idk if anyone has figured this out yet, but what does C&A mean? well, C has to be Caine, it just fits. But what is A? of course its Abel, like, what else could it be? As we could see at the start of episode 8, there is a red dot. (supposedly Caine) and you can see he was fed information, like an AI, but when the information grew stronger, the shapes he was making started to be more abstract. And then he was trapped in a box. Then a blue dot appeared, another AI, and some people refer to them as Abel, which makes a lot of sense, and C&A can stand for Caine and Abel. And when Abel is fed information, he actually makes the correct shapes. Then Caine breaks out of the box, and eats Abel, referencing the biblical story Cain and Abel. (before anyone asks, I'm not a christian-) So now Caine makes the correct shapes, but its actually Abel's, and you can see sometimes, his eyes flash red and blue. anyways, that's it for my theory. bye!
