Episode Connections

S1E01 - Pilot

  • OLIVIA about Walter in 'Pilot': "He does have a son."
    BROYLES: "Is he local too?"
    OLIVIA: "Not exactly."

      A reference to the fact that Peter Bishop is not from this universe.
  • WALTER in 'Pilot': "I knew someone would come. Eventually."
      Because he knew the universe would start to deteriorate due to his actions in 'Peter' and it would be traced back to him.
  • Walter checks Peter's eyes for signs of degradation in 'Pilot' to make sure Peter is still healthy after coming to this universe in 'Peter'.
  • Nina says cancer took her arm in 'Pilot'. In truth, it was damaged in the doorway between universes when she tried to stop Walter from crossing over in 'Peter'.

S1E02 - The Same Old Story

  • CHRISTOPHER PENROSE in 'The Same Old Story': "Someone paid him, the man I call my father. He should've let me die. That was his mistake. But he was blinded because he loved me."
      Walter made the same mistake, as shown in 'Peter'.
  • WALTER in 'The Same Old Story': "It's one of the inherent pitfalls of being a scientist. Trying to maintain that distinction between God's domain and our own. Sometimes I forget myself, but then you already know that. If you've read my file then you know the truth about Peter's medical history."
      We learn the full extent of Peter's medical history, and what Walter did to save him, in 'Peter'.

S1E04 - The Arrival

  • In 'The Arrival' Walter knows the Observer and says he and Peter crashed through ice when Peter was a boy. We see this crash, and we see the Observer save them from the icy lake, in 'Peter'.
  • WALTER in 'The Arrival': "Have you ever taken anything that didn't belong to you because you knew it was the right thing to do?"
    PETER: "This isn't about me."
    WALTER: "Maybe it is, Peter."

      Everything happening in Fringe can be traced back to Walter stealing Peter as seen in 'Peter'.

S1E06 - The Cure

  • Nina told Peter that she knew him as a child in 'The Cure'. In 'Peter' she is intimately involved with (and opposed to) Walter's attempt to kidnap Peter.

S1E08 - The Equation

  • WALTER in 'The Equation': "Every moment that passes is another moment that little boy's life is in danger."
      Walter's often not too interested in the personal aspects of cases, but this reminds him of what happened to Peter in 'Peter'.

S1E10 - Safe

  • Peter flipped a coin through his fingers in 'Safe' like both Peters did when they were near death in bed in 'Peter'.
  • PETER in 'Safe': "What's with all the toys?"
    WALTER: "They're your toys, son! From when you were a little boy."
    PETER: "Those aren't mine."

      They belonged to the Peter that died in 'Peter'.
  • WALTER in 'Safe': "I was under a great deal of stress at the time!"
      Walter was stressed when he hid the pieces of the machine in safety deposit boxes 23 years earlier. This episode takes place in 2008, so 23 years earlier was 1985, the year Peter died in 'Peter'.
  • In 'Safe' Walter said that Peter miraculously and spontaneously started to recover from his bird flu. In truth, Walter's Peter died in 'Peter', and Walter stole the other Peter.

S1E15 - Inner Child

  • PETER in 'Midnight': "Everything stolen is not necessarily lost."
      Peter was stolen in 'Peter' and was lost from Walternate's point of view, though we know he's alive and well.

      Walter showed how far he would go, across universes, in 'Peter'.

S1E20 - There's More Than One of Everything

  • SEPTEMBER in 'There's More Than One of Everything': "This coin looks similar to the one you're thinking of but it is from another place. There is more than one of everything."
      Both Peters have their own coin in 'Peter'.
  • Walter looked upset when he foumd Peter's coin in the lake house in 'There's More Than One of Everything' because Peter was holding it as he died in 'Peter'.
  • WALTER in 'There's More Than One of Everything': "Around this time something was lost to me, Peter. Something precious. I became convinced that if only I could cross over myself then I could take from there what I had lost here."
      Walter kidnapped another Peter in 'Peter'.
  • WALTER in 'There's More Than One of Everything': "To calm yourself, to forget what you were going through you took to collecting coins. This one was your favorite."
      Both Peters in 'Peter' had the same favorite coin.
  • Walter visited Peter's grave in 'There's More Than One of Everything' from when Peter died in 'Peter'
  • When Peter drove up to the lake house in 'There's More Than One of Everything' the camera focused on his car through a red panel of stained glass, foreshadowing that Peter was taken from the Redverse in 'Peter'.

      Just like Peter, who doesn't know that he took the place of the real Blueverse Peter who died in 'Peter'.
  • OLIVIA in 'Night of Desirable Objects': "Can you imagine living with a burden like that when all you wanted was a son?"
      This mirrors the struggle Walter went through in 'Peter'.

S2E04 - Momentum Deferred

  • REBECCA KIBNER about Shapeshifters in 'Momentum Deferred': "They seemed to have a certain glow about them. I realized I was recognizing people that didn't belong."

The last Challenger mission was Mission 10 and launched on January 28, 1986, and ended in disaster. This dream is based on Peter's childhood memories in the alternate universe before he was kidnapped in 'Peter'.

    PETER: "No, it's a bit mystical for my tastes. I never get it, myself. Maybe that's because I'm not on track with my own destiny."
