  • Trivia

    • Trivia: The glyph code for this episode is DEATH.

    • Trivia: The Observer can be seen in the crowd as Jones passes out the money, walking behind This Side's Lincoln just after he says, "Excuse me, Fringe Division!"

    • Trivia: The face on the hundred-dollar bills Jones passes out resembles Teddy or Franklin Roosevelt, rather than Benjamin Franklin.

    • Peter describes amphilicite as "It's not really reactive, like helium..." Helium is an inert, stable, noble gas, the second lightest element after hydrogen. Hydrogen, on the other hand, is a highly reactive element.

  • Quotes

    • Lee: I don't know, I've known Murphy since the Academy. He's always been a straight arrow.
      Bolivia: Oh, I just got kind of a hunch that this other Lincoln is telling us the truth.
      Lee: Must be because he has such a trustworthy face.
      Bolivia: See, I think he's kind of funny-looking.
      Lee: You're funny-looking.

    • Astrid: Walter's just discovered molecular gastronomy.
      Walter: I've liquified meat and then placed it in an alginate bath. It's really quite...
      Astrid: Quite disgusting.
      Walter: That's the thing about scientific inquiry--not every experiment is a success. But I hold high hopes for the Parmesan ice cream.

    • Lincoln: I need to be a part of this investigation. I lost a partner.
      Peter: I lost a universe!
      Lincoln: You're scared.
      Peter: Yes, I am scared. I'm scared that every day I stay here, the people that I love get farther and farther away from me.

    • Farnsworth: Are you really from another timeline?
      Peter: Yeah, I think so.
      Farnsworth: Cool.

    • Elizabeth: I saw how much you loved him. Your strength...
      Walter: Not strength! Hubris. And I've been punished for it ever since.
      Elizabeth: By whom?
      Walter: By God. By a deity, whatever you want to call it. And I understand, I deserve it. No man should do what I did.
      Elizabeth: You made a mistake. That's what being a man is.
      Walter: It was more than a mistake. I broke universes. I asked for a sign of forgiveness, but I got nothing. There is no absolution for me.
      Elizabeth: Well, I don't believe that. I forgive you, Walter. I forgave you a long time ago. And if I can, God can.

    • Walter: I lost the people I loved most and I imagine you miss them too, the people you've left behind.
      Peter: Yes I do.
      Walter: I will help you, Peter. I--I will help you get home. The last 25 years, I've spent thinking about losing my son. I thought I was an expert on loss. Maybe that's why you are here, because there are still things that I need to learn. What?
      Peter: I just spent the last several days with the other Walter, and I was very surprised to learn he was not the man that I thought he was. But I am not at all surprised to learn that you are.
      Walter: Is that a good thing?
      Peter: Yes, Walter. That is a very good thing.
