Loyalty is a complicated subject for Ada. It’s not something you’ll hear her claiming is all important and something to be strongly valued, but it’s also not something she writes off completely. Loyalty, in general, she finds somewhat of a hindrance -- things like house loyalty, for example, she will not subscribe to. Also, family loyalty -- just because they’re biologically related to Ada, does not mean she will stick her neck out for them ( unless not doing so causes significant harm to her ). She won’t harm them, especially not intentionally, because she does genuinely care for them and she would never appreciate people speaking ill of them but she won’t disadvantage herself for them. Loyalty has to be earnt, and blood does not guarantee that. Very, very few people are worthy of Ada’s loyalty. As in like, one, maybe two people. For those few people, there are no lengths she won’t go to for them. But for everyone else, Ada’s goal is her ambitious and her pursuit of knowledge and she finds loyalty causes complications that she’s not willing to subject herself to.
