so I have an idea (rant incoming). Since the drones are not biological life, they cannot grow. therefore, they need some way to age. Now based of of ep 3 (the promening) it is 3017 (or 3037 I cannot remember). that means their technology is probably very advanced, and they must know a ton Abt genes. so my theory is, they go to a special doctor drone thing, they look up the plan of growth(which is made based of genes), and then they make modifications. Now, in Uzi's video in ep 1 we see that a baby has a sticker with 'untrained neural network' on it. The drones also appear to have a need for schooling, and aren't smart right away like the usual Ai (ex: dumb robots appear sometimes). This means that their robot brain network things are not modified at that doctor drone I was talking Abt. So, since beau and crazy deer lady live underground and do not go outside, they have no acess to these special doctors. This means that crazy deer lady probably came underground at around uzi's age (they are Abt the same size, uzi may even be slightly bigger). We know that she's decently old because of her knowledge of drone parts and of her hideout. She stayed the same age cuz she did not visit those doctors. Crazy deer lady either found beau outside and brought him in, stole him/her when she left, or took them from a drone she captured. No doctors+ beau's body stayed the same, but he got smarter. He has other weird limbs cuz of crazy deer lady modifying him/her slightly so they can be of use. End of rant
