re: the cullen siblings, a summary.
edward: she has pretty mixed feelings about edward, mostly owed to his mind-reading. he’s the one who initiated the idea of adopting her into the family and so i think he’s kinder to her than most, more understanding because he has that insight into her head, and she likes that he can see her for more than what she did. however she’s not a fan of the idea of not having privacy, and feeling like she has to keep her thoughts in check so to not make him uncomfortable. other than the issues with his mind-reading, he’s her favorite cullen.
rosalie: rose is.. hardcore intimidating for bree. for many reasons that would be too long to list, and i think if anyone were capable of holding a grudge for what bree did ( even not knowing ), it’s rose. they have the potential for a good sisterly dynamic but bree would have to kind of overcome her fear of rose, and rose would have to learn to be gentler to her. i absolutely despise the fanon that rose would assume a motherly role over bree. she doesn’t allow anyone to do that, least of all rosalie.
emmett: GIANT, muscular man? bree is terrified of him from the moment she sees him and it only lessens slightly when she moves in to the cullen household. they get on well enough so far as banter goes but she hates being anywhere within grabbing distance of him. she could easily outrun emmett, but if he got his hands on her? she’s done for. after a few years, once she’s comfortable trusting him or anyone else, i can see them being pretty good friends just because bree has a lot of chaotic potential once she feels safe.
alice: basing everything on book alice, bree doesn’t really like her. alice pushes too many personal boundaries for bree’s taste and she doesn’t like the idea of someone forcing her to wear something or look a certain way so that she fits in with the rest of them, or having someone judge how she looks generally. alongside the fact that she’s jasper’s mate, bree is cordial but very distant from alice.
jasper: bree does not like jasper at all. at least initially. what he did in the clearing was beyond over the top, aggressive, and even manipulative ( using his gift to make her angry so she might attack ). he has this very utilitarian feel about him and if his behavior with bella in bdp2 was any indication, he would not ease up on bree even after she became a ‘family member’, because he believes she’s a dangerous newborn that he has to whip into shape. she hates being around him and hates talking to him.
bella: besides edward, bella is the one bree’s closest to. they’re both awkward as fuck and i’m 100% sure bella is very understanding of what bree did in the army, and of course doing her bella thing and apologizing for being the reason in the first place. that’s something that bree appreciates even if she doesn’t find it necessary and sticks to bella... pre-vampirism. vampire-mom bella is just too weird and foreign for her to spend lots of one-on-one time with.
renesmee: not sure if i should count ness as a sibling but idk what else i’d count her as so. long story short, renesmee creeps her the fuck out from the get go. at least how she’s portrayed in canon. if she behaved a little more like a normal kid then bree would probably be cooler with her, but that weird... demanding little creature with an iq of 150 while looking like a 4 year old makes her skin crawl. they almost never interact until ness has matured and at least looks as smart as she is.
