and oh my god the redemption scene
it was so well made? like it starts up with caine curling into a ball (like the sphere he used to be, at the very beginning), and all kind of data goes zooming past (like the very beginning!). and he does actually fully go back to basics! it was shown a few episodes that he started off generating basic shapes, and then went into these weird, abstract ones.
but now, making the stairs? bridging the gap? he's back to those basic shapes. making cubes. then cylinders. making a foundation from the ground up. relearning everything from scratch. relearning how to be a host to his humans.
and then he reaches the barrier! and his first instinct is to whack it with something hard and pointy, to brute force it until it breaks! but it... doesn't work.
just like it didn't work with his humans. he couldn't FORCE them to love him, to love his adventures. there was no perfect algorithm to make them happy.
at the end of the day, what he had to do was reach out, and actually understand them for the first time.
(same with the barrier. when he touches it, you can see the information flowing into his hand. he's actually absorbing everything, for the first time.)
and he reaches the exit door, and he goes and learns everything he can about his humans. because his 'perfect' mind scans, his 'perfect' bodies that he put them all in- they still weren't right.
he actually bothered to learn all of them. of their imperfections. of what's messy, and doesn't show up properly in the mere ones and zeroes of their data. he learned the things, the people, they all loved.
and he's connected to that door, the information about all of them- with red strings (of fate?). because for the first time- he loves them.
he was made as an ai. he was never programmed to be able to love. but for the first time, he's trying. he was made to learn, and he's finally learning.
he gives up on perfection, and is finally able to try and be one of them.
