Whatever happened to her friend, Shane?
He was my favorite character. I was hoping Carys might, in the end, see him for all he really was. The ending was a bit ambiguous. Anyone wanna conjecture what might have happened to him?
shareWith means and motive, I would say he murdered Tyler when he could, having the tools in the mortuary to cover it up, and blackmail Carys into staying with him. That's what I'D do, anyway.
But that's only speculation...
