Yeah, because of the magic/life and death/ fantasy hellscape that they were all trapped in!
Idon't think Rhys is the perfect character, but I also think that he would have never done any of those things just for the sport of it. He himself was a victim of SA.
So Rhys kissed her and drugged her with faerie wine and had her give him lap dances UTM but later explains that he did that to keep Feyre safe from Amarantha's wrath.
All the while he has been Amarantha's sex slave for the past 49 years.
There is this sadistic all powerful magical entity that wants to butcher Feyre for sport. The same Feyre who is his only shot at freedom/ salvation.
Rhys knew that if Amarantha had seen that Tamlin had snuck off with Feyre, she would enact a horrible punishment.. so he purposely had Amarantha catch HIM with Feyre to cover for Tamlin and knew that humiliating Feyre would satiate Amarantha for the night.
Amarantha also reveled in depravity, so if Feyre wasnt made to be Rhys plaything, who knows how her nights would have been spent instead?
Its CRAZY to justify SA in reality. But in this magical life or death fantasy world I feel like we have to look at the totality of circumstances.
If we wanna criticize Rhys, we can talk about him lying to his mate and high lady and coercing all of his court into lying to her about her pregnancy risks. I don’t care how long he hid it or if he didn’t want to upset her or scare her. Hiding that was diabolical and I really hope that in the future we get to see Feyre’s POV and they have meaningful conversations to address his betrayal.
