Is it just me or the real reason Jezera wanted to forcibly recruit Rowan because she wants to mold him into someone worthy of ruling alongside her?
To recap:
- When they talk about demon bastards, according to X'zaeratl for a demon lord and a human to have children they must genuinely love each other. She also comments that the previous half-breed she met before the Twins had a sad and lonely ending, as she never found an equal to share her ambition and stay by her side.
- As Arzyl has proven and taken advantage of, Jezera is quite possessive and jealous that Rowan will be taken from her. In this specific scene, Rowan himself also notes that Jezera had been teasing and denying him up until then, but in her eagerness to humiliate and rub in Arzyl's face that he belongs to her, she decided to abandon her strategy because she basically felt threatened of losing him.
- In the scene where Jezera teaches him how to dance and etiquette, in a rare moment where he catches her off guard he notices that she seems genuinely happy while they dance, only to revert back to her manipulative and seductive self when she notices him looking at her.
- In the Rastadel battle scene, if Rowan is submissive to her, Jezera will say that he is the only man worthy of her and being by her side, and during their sex she comments that for a demon lord to have children they need to love each other and tells him in other words to impregnate her. Assuming this wasn't a tease and she was sincere here, it would strongly imply that she was genuinely in love with him.
- Referring to the same Astarte scene where Rowan is not submissive, if he chooses to "praise" Jezera during their sex he tells her that he hates and loves her for pushing him beyond his limits, which surprises and distracts her enough for him to be able to win their sexual battle. I don't think it was a coincidence that Jezera was defeated essentially because Rowan declared his love for her when she wasn't expecting it.
My point is that while Jezera is certainly an evil seductress, dialogue and events in the plot lead me to believe that she actually desires to have someone to be by her side with whom to share her ambition, which is why I assume that behind all the teasing and manipulation she does with Rowan, at some point she chose him as the one who would be worthy of her, hence why she is so seductive and possessive of him.
In other words, Jezera ultimately, and in a delightfully ironic twist, wants to have a sort of healthy romantic relationship with Rowan.
