for as long as i've written albedo, i always headcanoned him to hold some sort of resentment for rhinedottir. and while canon would contrast this, i still like exploring that small 'what-if' that's lingering in the back of his mind.
so, i'll amend it. albedo DOESN'T hold a whole lot of resentment for her or the way he was raised/created/being dropped off in mondstadt, but he does think she's reckless as a member of the hexenzirkel, thinks she is more dangerous than even he knows.
he hasn't seen her for years, whatever she's up to now is beyond him, but albedo does hold some level of caution for whatever the hexenzirkel is up to, as well as the shift in the air to signify things across teyvat changing overall.
THAT SAID, she is his mother and master, and he owes a lot to her. whenever se sends a message, albedo takes it in with unwavering attention, because he wants any crumb of knowledge of what's going on and what her plans for him are. he refuses to slack off in his thirst for knowledge/quest to perpetually better himself, especially where khemia is concerned, because he does not want to let her down.
so in short, i still headcanon that he has very complex feelings for rhinedottir, and it shifts with each day. he either resents her, or he greatly misses her, and he'll take whatever family he can get from her creations (durin, sebas, even subject two verse depending).
he might be non-human, but albedo is still human, if you catch my drift.
