Hell, yes! He did everything he could to protect and help Feyre. He went up against his beat fiend and saviour of over five centuries for her. What else could he possibly have done? Should he have completely sides with her against his friendship /bond with Tamlin. He knew her for a freaking year! Love her but she did him wrong. He needs to get his recognition.
And Tamlin...he loved her. At least she recognized all the good he did for her and her family and tried to be respective of their history together.. even when she was falling for Rhys. Should he have done more, tried harder to help her under the mountain? Yes. Should the first thing he tried to do was screw her ...no. And after that, he was a bit over protective. What happened changed both of them drastically... he dealt with it the way he knew how. Should she have chosen him over Rhys....hell, naw! That's my boy! Rhys sacrificed everything for a woman he knew was in love with someone else. Even under all that duress and danger. He did everything he could to make her comfortable. He did what he did to protect her and give her strength to overcome what she had to go through.
