I heard that the finale is in December. Anyway i have brought every episode of season 4 and something doesn't add up. I believe it was episode 3 when David went too her house and tried too killed ( so called ) Emily. He took one look at her before Nolan saw him. David already knew she was alive. I believe he's knows everything and just want too hear the truth from the everyone else and all David is getting is nothing but lies. I believe this thing between David and Victoria is an act. Think about it. Conrad and Victoria set him up. David killed Conrad. I believe he's trying too get even with Victoria but in his own way. Don't you agree?
