Just finished watching season 4 and it was excellent yet again.....However, I do feel a little short-changed by the ending. Why did Liv kill Theo?? Was it simply because she wanted to be the sole heir? Was it because he was a Galloway? Was it because of how he described her actually being a member of the family? Or was it something to do with his confession about the car crash? Was she there, did she know someone who was??? I was expecting a short back story at the end explaining it...but in never happened
