An Origin Story was one of those titles that are not easy to decipher. It might refer to how the Observers get their abilities, or to how Peter started down a reckless path, or even in a twisted way, how this might be the beginning of something far bigger than we are able to see now. No matter the meaning of its title, the episode provided riveting details on some of the Observers technologies, opening the possibility of another path to freedom than Walter's plan, but ultimately, at its heart An Origin Story was about the Bishop family's loss and how each of its members coped with it.
I cried this episode but not the last. I'm so confused. Love Fringe!
