Fringe: Worlds Apart

"Worlds Apart" is the twentieth episode of the fourth season of the Fox science-fiction drama television series Fringe, and the series' 85th episode overall. It was co-written by series story editor Matt Pitts and DC Comics' Nicole Phillips based on a story by co-producer Graham Roland. Charles Beeson served as director. The series depicts members of a Federal Bureau of Investigation "Fringe Division" team based in Boston, Massachusetts as they investigate a series of unexplained, often ghastly occurrences, which are related to mysteries surrounding a parallel universe. In this episode, David Robert Jones (Jared Harris) employs former Cortexiphan subjects to create simultaneous earthquakes across the globe, leading Dr. Walter Bishop (John Noble) to hypothesize that the end of both the prime and parallel universes is imminent. The two worlds must decide whether to close the bridge that was repairing the parallel universe, or they may all face destruction. "Worlds Apart" first aired on April 27, 2012 in the United States. The episode featured the return of David Call and Pascale Hutton, two guest actors not seen since the second season finale. It aired in the wake of the official renewal of a fifth season for the series. An estimated 3.1 million viewers watched the episode, a small increase from the previous episode. Critical reception was generally positive, as many highlighted the performances as well as the scene between the two Walters.
