It's kind of funny. Anubis doesn't even dislike her, he just wants her gone because he sees it as human = unpopular = threat to his bestie's rule. So he's totally missing the fact that she's in the middle of winning over the public one piece at a time and making his bestie a better, stronger ruler, which will also lead to popularity. Overall, in the medium term she's gonna be good on his terms, but he's stuck in his initial assessment. Ironically, she's on the path to popularity precisely because he keeps setting her these tough tasks so she looks awesome when she passes them with flying colours.
