What a brutal killer! Especially when he used the car to decapitate the woman. I like brutal killers though. And I guess he could have swam away far enough for the bullets not to him hit, he was under the water with Blake for quite some time.
But to kill the last guy over some car keys is doesn't seem like him, it has nothing to do with the families and why he was left with another woman as a baby.
Like the episode very much!
