Love him! Such a cool character and very well written. I love that he makes Rhys perfect for Feyre. His possessiveness is so real, he loves Feyre so selfishly compared to Rhys who while believing Feyre was his mate was willing to let her marry Tamlin if she chose to.
I might be in the minority but I dont hate characters, I hate bad writing. If he's well written (which if im not clear in my first sentence, Tamlin was) then I cant help but like them. His character arc was true to his development the whole way through the series.
