"I think the real kind of thrust of it was to show that Shauna is still really traumatized by her past. I think that's one of the big themes of the show is, ‘how do we escape past trauma? Can we move on?’ I think one of the things that they were playing with this Adam character was that he was trying to present himself as being genuine and honest and earnest, and no one believes him. I think that is actually quite a clever way to demonstrate that our own trauma can project itself on others and, obviously, Shauna killing him a combination of it. She cannot believe in goodness anymore. She cannot believe in honesty anymore, and she goes so far as to murder an innocent man."  — Peter Gadiot
