Because of Maura's displays of intimacy and knowledge of Jane, Jane's response of outright aggression becomes more meaningful. Her posture shift does not only indicate a desire to threaten Dean's intrusion onto her crime scene but also Dean's intrusion into her intimate connection with Maura. Jane slants herself as if she's offended she's not an option.

Um... what is that thing about how you point your feet at the person you're most engaged with in a social situation? There has to be some meaning about where you point your pelvis...

Anyway, later scenes show us what Jane looks like when she's inviting romantic attention from men, and that involves her making herself smaller, making herself look less sure and aggressive, and leaning into traditional femininity. It's quite the opposite of what she's doing here, which I read as laying a claim... on the crime scene but also on Maura.

This is fascinating because, at first, I'd mistakenly believed it was Maura's queer jealousy that cropped up first, but this reading actually presents the opposite scenario.

This kind of framing comes up again, in this same episode, when Jane flees her apartment to stay at Maura's for the night. In Maura's guest room, Jane spies to see who Maura's nighttime visitor is, and then they have that exchange on the bed. The question of Maura's potential attraction to Jane comes up in the same brief span as the question of whether or not Maura has ever had a crush on the same guy as her best friend, intermixing these two potential attractions in such an interesting way.

It's almost like Jane is giving mixed signals here. She's asking Maura if she's attracted to her only in joking terms... because for some reason she doesn't feel like she can ask it seriously. But as their conversation turns towards Dean, and their supposedly shared attraction to him, I'm instantly reminded of the concept of some of Eve Sedgwick's work on homosociality and erotic triangles and how those theories have impacted my own understandings of love triangles in media. I'm going to way oversimplify it here, but essentially when two people of the same gender are vying for the attention of the same different gendered love interest, I'm more interested in the bonds presented between the two of the same gender — whether it's rivalry, intimacy, potential sexual attraction (especially when it's wrapped up in taboos, social norm violations, and repression), or some complex mix of the three. And just, wow, this connection between Jane and Maura is ripe for that kind of reading. It becomes really easy to read Jane's "pursuit" of Dean as a way of attaining conventionality through a connection that also engages her potentially unconventional attraction to Maura (and a resistance to admit that) by being with someone Maura finds attractive. Jane isn't really showing attraction to Dean, but she is very much going for the closest conventional relationship she can that partly expresses her repressed, "taboo" attraction. (I wonder now if this contributed to my reading Jane specifically as a lesbian, rather than bisexual, through most of the series, but that's a bit besides the point).

Doesn't this just make it so interesting how Maura had physically insinuated herself between Jane and Dean?

It's also significant for me that when Jane does pretty herself up with lipstick to go see Dean, she rebuffs him and is consistently iffy about him despite the so-called attraction she admits to Maura. It's also very much giving that repressed queer experience of having a crush on a girl and being so jealous of her relationship, but not being able to conceive of yourself as queer, so mistaking that for a crush on her boyfriend. You know?!

Later on in the show, when Jane is with Dean, there is still so much to this dynamic. Maura calls Jane on a date with Dean and she immediately runs to meet her, choosing her, prioritizing her. It's what makes it so sick-inducing when, after Maura reveals that she doesn't know if she wants Jane to catch Paddy, Jane goes on to tell Dean the FBI agent with a hard-on for catching criminals at all costs about his presence in Boston in a specifically romantic scene. You know, which then causes a chaotic scene that requires Jane to shoot Paddy after feeling up his daughter to set her up on a sting... There was so much wrong with that, I'm honestly surprised there was a moment in Maura's tirade for her queer jealousy to slip in, but it does.
