STAGE TUBE: Sneak Peek - FRINGE Season Finale Airing Tonight

In part-two of the season finale of FOX's FRINGE, Nina (Blair Brown) Peter (Joshua Jackson), and Olivia (Anna Torv) help a dying girl in "Brave New World". The episode airs tonight, Friday, May 11 (9:00-10:00 PM ET/PT) on FOX. Get a sneak peek below!

Set in Boston, the FBI’s Fringe Division started when Special Agent OLIVIA DUNHAM (Anna Torv) enlisted institutionalized “fringe” scientist Walter Bishop (John Noble) and his globe-trotting, jack-of-all-trades son, PETER (Joshua Jackson), to help in an investigation of an airline disaster that defied human logic. After the defining case was solved and furthermore revealed to be one of a series of unusual incidents linked together, the unlikely trio – supervised by Special Agent PHILLIP BROYLES (Lance Reddick) and assisted by ASTRID FARNSWORTH (Jasika Nicole) – was formed. Rounding out the roster is LINCOLN LEE (Seth Gabel), an agent from “over there” who serves as an integral part of the narrative.

As unimaginable events continued to unfold, the Fringe Division’s investigations often lead them to the important science and technological corporation Massive Dynamic and its enigmatic chief executive, NINA SHARP (Blair Brown). Olivia discovered that she was a test subject of Dr. Bishop and Massive Dynamic’s elusive founder and chairman WILLIAM BELL (guest star Leonard Nimoy) as a child. When she uncovered this, she learned of a parallel universe and discovered her ability to detect anything from this alternate world. Shockingly, it was eventually revealed that Walter kidnapped Peter as a child from “over there” after his Peter died, thus creating an imbalance between the two universes.

As life in these two interconnected worlds was explored, complications quickly began to ripple. Peter’s romance with alternate Olivia resulted in a baby, and the DNA from this child allowed alternate Walter to activate a “doomsday device” – a device he believed would destroy our world in order to save his. Ultimately, Peter used this device to build a bridge between the two worlds and sacrificed himself in the process.
