These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Strangled by the Red String: In Star of Doom, Sonja is in love with a fellow mercenary, Daron (though it takes her a little while to admit it). Note, that's in love; we don't see them fall in love, which presumably happened during the month or so they knew each other before the book opens. Because of that, and because what we see of Daron makes it seem like he's not really Sonja's type, the romance doesn't feel earned.
Foe Yay: With Dark Annisia in the Gail Simone series. Not so much subtext as text, since Annisia was undeniably in love with Sonja at one time and may still be.
Big Lipped Alligator Moment: The random dancing topless girl in Gedren's scrying pool. In-universe it's treated like he forgot to re-tune it after his, er, "private entertainment".
The film's sexual politics are all over the place. First of all, it begins with a Rape as Backstory, which is rarely a good thing, and then Sonja's strength is granted to her by a spirit, seemingly to allow her to get revenge on Gedren and suggesting that she didn't put much effort in herself. Later, the weird Mr Miyagi/Padme Amidala arena master telling Sonja she must learn to like men better, which, when you think about it, is basically him scolding a victim of gang rape for being a little wary of sex. How unreasonable of her.
The Big Bad is a lesbian who responds to rejection by having the rejecter's family murdered and the rejecter gang-raped.
