Fringe: Season 2, Episode 16 - ProjectFreeTV

2 - 16: Peter

Walter explains to Olivia how, in 1985, he invented a window-like device that allowed him to witness events in a parallel universe. Walter's story unfolds as a flashback: A younger Walter observes that in the alternate universe, the other Walter (whom he nicknames "Walternate") is working on a cure for the genetic condition that is killing young Peter in both universes. One evening, Peter dies in Walter's arms. After the funeral, Walter witnesses his alternate self successfully synthesizing the cure, but Walternate is distracted by an Observer and misses the experimental result that confirms his success. Walter decides to perfect the cure and then travel to the parallel universe to administer it to the alternate Peter. Walter finishes preparing the medicine and goes to frozen Reiden Lake to open a portal. Nina Sharp arrives and tries to to stop him, fearing that breaking the barrier between the two universes will destroy both. In their struggle, Walter falls, but makes it through the portal; Nina hangs on to him as the portal closes, and loses her arm. Walter discovers that his fall broke the vial of medicine. He picks up Peter and returns to the other side to make more of the cure, but the frozen lake cracks beneath them and they fall through the ice, into the freezing water. The Observer September saves them, explaining to Walter that Peter is important and must live. After curing Peter, Walter renounces his original plan to return him to Walternate because Elizabeth, Peter's mother, does not wish to let him go.
