What did John think Kevin did to Evie?
Killed her, kidnapped her...departed her?
shareJohn is a very violent guy, he's already shot someone, he is a delusional, paranoid schizo. I swear you see the way he talks, like there is some worms squirming around in the back of his brain. The writers thought it would add more drama, why else? They painted a picture of this creature and they called it John. The writers have this thing that is always pushing them, It is the ego. Right. Story wise, looking st it flatly, John an ex-con is very suspicious from his life in prison. He's in constant "survival" mode. Kevin is acting kind of nutty and John picked up on it and, there you go.
Just what I think...
