yes, i do!! with the caveat that we have such limited information on lovelace's crew, what we do have is almost entirely filtered through her perspective, and we kinda... know rhea the least. as much as i find eris a fascinating character too, i wish we'd heard more of rhea.
which is kind of the first thing: rhea is the only AI character in wolf 359 who doesn't have a voice. (we don't hear hyperion's voice, which is supposedly not integrated yet, but he's not even really treated like a character in the scene he's in. and that's a whole other thing.) for hera in particular, she feels a physical disconnect from the others, but the fact that wolf 359 is audio only makes her an equal presence from the perspective of the audience. (which carries over to the live show, where the other characters may not be able to see her, but the audience can, etc.) rhea's situation is kind of the opposite, where her words can be seen by the others, but the audience can only hear or infer her words via what the others read out loud or respond to.
rhea clearly cares about her fellow crewmates, and seems to get along with lambert in particular. lovelace's log: "and communications officer lambert is... communications officer lambert. so an enormous stick in the mud. [...] i heard that, rhea. you are expressly forbidden from telling him i said that." - a sentiment it's easy to imagine early minkowski expressing about eiffel and hera, for the opposite reason. in a more direct parallel, rhea reassures lambert that he "does a great job"; in bach to the future, hera tells eiffel he's "actually very good at his job." the difference in context highlights their priorities; eiffel and hera are having a heart to heart about worthiness, while rhea really is talking about lambert's job - work is important to him, and most people around him don't respect or appreciate his work. what we can infer about rhea is that she's... well, the kind of person who would be lambert's friend. straightforward, rule-following, and professional.
(even something like "see, rhea? i told you someone read [my reports to command]" indicates that they talk to each other a fair amount, but also serves as a mirror to eiffel's belief no one listens to his logs.)
maybe the most interesting thing to me about rhea is her defense of eris: "it's just the way they programmed her, back off." ... again, the complete opposite of how hera might respond. eiffel tries to "defend" her in a similar way in ep 7 - "you can't really hold that against her; it's just her programming" - and she finds it incredibly insulting. with all of that taken together, with how lovelace, lambert, and rhea are in many ways intentional opposites to minkowski, eiffel, and hera, it really makes me wonder how rhea identifies or perceives herself.
i think hera is functionally human, both in her singular, consistent image of herself, and in her role in the narrative. eris appears human to lovelace, but is clear that it's how she sees "a version of herself." whether that refers to that iteration of eris having multiple versions of herself, or if it refers to all of the iterations of her who exist: either way it's a reflection of the way eris exists, and her acceptance of that. by extension, the fact that we don't encounter rhea in any way other than beeping sounds and implied words on station monitors... kind of says something narratively, i think. going back to her lack of voice, even that level of distance and abstraction takes her further away from 'human' perceptions by the audience, while she's obviously still a full person with her own priorities, perspectives, and opinions. i think it's very interesting to consider she might prefer her state of (lack of physical) existence in a way hera clearly does not.
