Great points, I would love to explain, but the goal is that it should be clear in game.
When it boils down to it, Android is a human in a (mostly) metal body. But how do I explain that she has human issues when she's capable of much more? It's tough, but this is how she works:
She is a very new soul, still discovering how the world works. She has all the capabilities of an adult if an adult was dropped in a completely unfamiliar environment and had to learn everything from the start again. Nothing in our reality comes natural to her, so she must discover what reality is. And her whole world has been the hotel, and the people in it. Naturally her first priority would be to protect them and interact with them. Protection is easy, it's a science, but socializing is an art, and that's what she struggles with specifically. Anyone with autism like myself knows that these things don't come so naturally to us, and it's almost impossible to learn how to be social from someone else, you have to actually practice it and discover what works.
Android absolutely has the capability to do all of the things you mentioned, she would just need to practice or download the information, of which she has limited storage. So she must prioritize the memories and feelings of her loved ones.
Regarding her EMP protection, most of her parts especially early on are ancient technology in the context of this universe. It's 30+ years old. But you're right, that is totally a possibility, and a great idea for an upgrade.
