Despair. That's definetively not the word to describe what Emma felt when Norman left her, but maybe it's the closest one. Such feeling is too cruel to be described by a single word. Seeing your dearest friend leave for the sake of your survival is not only agonizing, it's scary, frustrating. And she didn't have the one that helped her in these situations, not anymore.
But then, well, miracles happen, right?
