My perents always told me beggars can't be choosers, but I see
I think the reason neither is very invested in her is because there is no challenge, she is already broken. She's just a sex puppet at that point, just one step above masturbation. If she wasn't useful for messing with Rowan, they wold likely have tossed her to the orcs and forgot about her.
On the other hand, if Andras was aware that she that she was recovering, I could see him having fun watching her stuggle as long as she could to resist her urges, and would probably get off the the defeat in her eyes when she eventually failed. But she is either already claimed by Rowan or escapes before it can come to that.
You will notice that there is no indication that Andras fucks the maid staff. This is because the maids belong to Jezera. If Andras were to order a maid to fuck him, I'm sure she would, and then afterwards she would report to Jezera and would cause a fight between them, just not worth it. If a maid became enamored with Andras and flung herself at him, I'm sure he would fuck her, then he would let Jezera know that she has an unfaithful maid to deal with, big mistake for the maid.
The thing is that if Alexia is on Jezera's path, she is very unlikely the fling herself at Andras since it is all about her becoming dedicated to Jezera. Is it possible that Andras could managed to seduce her anyways, maybe. But is it worth the fight that would happen afterwards? And it remains true if you reverse the roles as well.
If anything I suspect they see seducing Alexia as a friendly competition. No since in being a sore loser when you couldn't seal the deal fast enough.
You know if I was the FBI, I would be MORE suspicious of the guys that I can't verify are looking at porn. What are they looking at that they feel the need to hide.
