okay so i'm in the process of rereading pjo and i just got to botl and i want to talk about my girl annabeth. i feel like a good majority of the fandom mischaracterization of annabeth comes from botl, specifically because she was rude to rachel throughout the book, and then everyone just assumed that because she wasn't nice to rachel she must be a bitch inherently, on top of being this fucking emotionless shell of a person, which is wild to me because i don't know how her being rude to one (1) girl automatically discredits everything she's done in the past three books. i feel like it stems from a complete misunderstanding of why she was rude to rachel. let's make this clear: she wasn't rude to rachel because rachel was a potential love interest; she was rude to rachel because she was scared.
everyone she's ever loved has been taken from her in some way: her mom being absent because she's a goddess and not really wanting anything to do with annabeth; her feeling like her dad and stepmom didn't want her around (losing her real family); thalia, her found sister, sacrificing her life to save annabeth, and then leaving her again to join the hunters; luke betraying the camp, but more importantly betraying annabeth on a much deeper level because he was her only family. he promised her that he would be there for her, no matter what, and then he leaves her, just like everyone else. even grover left her, in a way, because he went out to search for pan and wasn't around. the only close person who hasn't left her at the point of botl? percy.
but she knows about the prophecy at that point, so she's spent the better part of three years resigning herself to the fact that her best friend is going to die when he turns sixteen and there's absolutely nothing she can do to stop that. she's spent the better part of three years trying not to fall in love with him because it would only hurt worse when the time comes. if i had to bet on it, the reason she was thinking about joining the hunters in ttc is because if she isn't around him (and also can't because she's a hunter), she won't become more attached to him than she already is. if she separated herself from him, it would hurt less. except here's the thing: by that point, she couldn't make herself do that. she couldn't make herself willingly give up percy yet, because it might not have been him. if i had to guess, when thalia came back, annabeth stopped worrying about percy dying---just for a little while---because she thought that thalia was going to be the child of the prophecy after all. so when thalia became a hunter, she was mentally prepared to lose thalia again. but that means that every fear she had about percy being the prophecy kid before thalia came back to life resurfaced full force, and now suddenly annabeth has a year and a half left with him when she thought that she might have longer. so despite the thought of her joining the hunters to prevent herself from getting too attached, she hadn't metnally come to the point where she was ready to give up the small hope that he would live.
which bring us now to botl. like i said, i'm just now rereading the book (and i'm only on chapter 1 but i started thinking about annabeth and here i am). annabeth is mean to rachel because she's terrified of losing percy too soon. sure, at this point she knows the prophecy is his, she knows come next summer she probably won't have him anymore---but that's just it: next summer. she's preparing herself to lose him in a year, not immediately. so when someone comes along that presents a way for her to lose percy, of course she gets scared, and she gets defensive about it. it's not even the fact that rachel was a potential love interest, it's more so the fact that rachel was a mortal, and not part of their world. if percy was with rachel, there's a good chance he'd try to leave the magical world behind, and, more importantly, leave annabeth behind, which she wasn't ready for yet.
hell, that's exactly what ended up happening in the beginning of tlo! annabeth wasn't upset because he was spending time with rachel, she was upset because he was spending time in the mortal world rather than her world and, in her mind because of all of her past experiences being abandoned, that translates to "percy is leaving her," and it was way earlier than she thought, and she wasn't ready. so what does she do? she tries to protect herself. she puts walls up and tries to act cold and distant because she's coming to terms with the fact that she's already lost him. she's already lost him.
and like, was she jealous of the fact that rachel was a love interest? probably, yeah. but i think it's also just important to know that there's something way deeper to it. annabeth isn't being a bitch for the sake of being a bitch, and she's not just jealous of rachel because she was a girl that liked percy. she was upset because he was getting further and further away right in front of her. he was leaving way quicker than she was prepared for, so a lot of the stuff she said to rachel came from a place of fear of losing percy, and anger at rachel for trying to pull him into the mortal world, effectively leaving her behind and adding another person to the list of people she loves that have left her.
