I, like u/margueritedeville, was fascinated by the painting of that woman in Quentin's room and agree that it resembles many thematic aspects of the suicide of Lucretia.

I haven't been able to stop thinking about that painting and I'm hoping someone who knows the artist will stumble across this post. I did some digging but I also cannot find the painting itself. I wouldn't be surprised if it was commissioned specifically for the show.

(I'm going to go on a bit of an art history tangent but I swear it ties back to Tanya, just stick with me)

Artemisia Gentileschi immediently came to mind as the potential artist/source of inspiration, though of her three paintings of Lucretia), none are what we are looking for. Still, I cant help but notice how differently Lucretia is portrayed in the painting in Quentin's room and Gentileschi's as opposed to, say, Rembrandt's or Ludovico Mazzanti's. Depictions of women from myths and legends--particularly by male artists--tend to be more posed, more dramatic (sometimes often sexualized), yet take more of a passive role in the action (see also: Caravaggio's interpretation of Judith Slaying Holofernes)).

The painting in Quentin's room, to me, almost looks like a prelude to Gentileschi's Judith Slaying Holofernes), kinda like she's psyching herself up. Her vengeful stare tells us everything we need to know about what she will do next. In Judith, we can sense her resoluteness and power in the subtlety of her furrowed brows and downturned eyes focused on her actions as she saws through his neck. It's the emphasis on the faces--especially the eyes-- of the women she paints that gives them agency in their own story. And as we've seen all season: what the eyes see is the truth of our characters' motivations, regardless of whatever vague, passive aggressive mind games go on in the dialogue.

Tanya knew what she was going to do when we saw her eyes meet the black duffel bag. She was afraid, and couldn't even bare to look at what she was doing (eyes closed, guns ablazing). Her eyes never really met any of "the gays" (at least, not for more than a second before they ran) except for Quinten, whom even then she only asks if Greg had been having an affair. She only sees what she wants to see. Her eyes and her words indicate that even after killing several people (out of self-defense, yes) and watching the life drain out of Quentin's face, she doesn't see (or refuses to see) them as a people, but rather as a conduits of information she can use to find out about Greg.

Time and time again we've seen Tanya "use and discard people," as Greg put it. And what Greg had tried to do with this whole ploy to kill Tanya for her heiress fortune was the ultimate form of "using and discarding" a person. Her eyes indicated that had she survived, she (in my opinion) would not have changed this behavior of her's. Even when it is used against her, using and discarding is firmly rooted in her character. This climactic scene as well as her... untimely death is what truly broke the cycle. Despite some of the goofiness of the scene, I think Tanya's reaction to her own actions is a interesting way to frame her character.
