The ending was pretty brilliant



Clive is definitely not the best detective around But at least he started figuring out Liv was getting her personality changes from the victims
I do understand he doesn't get that she's a zombie: when you don't know that stuff is real, and you don't believe in that stuff (although apparently he does believe in psychics ), your mind just doesn't go that way. You think of all sorts of (reasonable) reasons Liv does what she does, but not 'zombie', because that's farfetched
