River: I wish I was around during your time. When there were real heroes.
Peter: Well, kiddo, you're my hero for giving me a nice, strong jawline.
Astrid: Walter, is there a mine where you are?
Walter: Mime. The only mime that I know of is Marcel Marceau. What's he got to do with any of this?
Astrid: No, a mine.
Walter: (exploring a mine) In 1923, a mine collapsed in Peru. The trapped survivors were forced to nourish themselves on the dead.
Peter: Thanks for that, Walter.
Edwin: You're not a coward if you're frightened. That's not what it means. You're a coward if you know what needs to be done and you don't do it.
Edwin: There's a time for recording history, and there's a time for making it.
River: A hero died. Sacrificing himself in order to get the Fringe team resources they need to save our world. Edwin Massey, the recorder of history, made history. He will be greatly missed. Like other great men before him, he gave his life selflessly in pursuit of freedom... and a better future.
