The thrilling worlds of Fringe come to a mind-blowing end in the 100th episode and two-hour series finale as the team faces off against the Observers in one final battle.

In the fifth and final season premiere, Peter and his daughter Etta (GEORGINA HAIG) set out to find out what happened to Olivia.

The Fringe Team orchestrates a Fringe event of their own.

In the aftermath of Oliver's fight with Ra's al Ghul, Diggle and Arsenal continue to protect the city in the Arrow's absence. However, after three days without hearing from Oliver, they begin to fear the worst may have happened to their friend. Felicity refuses to believe that Oliver could be dead until Merlyn pays the team a surprise visit. Thea suspects there is something more behind Oliver's disappearance and asks Merlyn for a favor. Meanwhile, Ray tests a part of his new suit and Laurel takes up the mantle of the Black Canary.

The Fringe Team goes on the offensive.

Trying to recall his plan, Walter takes an LSD trip down memory lane. Meanwhile, Peter and Olivia trace a mysterious signal into the woods, where they come upon a grisly scene.
