I knew that he would rape her from the sex scene in ep 1. I watched through my fingers though, I thought it was very, very well done. You can understand why she doesn't LTB or go to the police, because they have such a combative sex life anyway and she instigated sex, so its easy to think "he got carried away", i did a mini-vom at the hand spit.
I think the ds with ASD is wonderful, my heart breaks for him, he is so unhappy. Its also refreshing to see DT in the role of utter wanker.
