The idea of waking up in an apparently strange place with amnesia can produce some fascinating stories with the main character struggling to cope with a world that appears dark, dangerous and unknown. One of the best examples of this would have to be the Bourne Identity, with Jason Bourne waking up and having no idea where he is, who he is and why people are constantly trying to kill him. In face, much of the action set pieces are specifically designed around the notion that this characters body remembers all of his special forces training, but he doesn’t remember who he is or what he is supposed to be. Amnesia obviously doesn’t have this sort of set up, and Heroine certainly isn’t an amnesiac Special Forces agent with the ability to kill at a moments notice, but she could be. That is the strength of amnesia stories, regardless of who the characters might be at this moment in time, it is what they could be and what they have forgotten about that helps to move the story forward. That she simple wakes up in the backroom of a restaurant, dressed as a waitress, and clearly a member of the staff but with no recollection of what has happened would obviously come as quite a shock to most people.
