For almost four seasons on “Fringe,” the mysterious beings known as the Observers seemed content to watch as the Fringe team attempted to save two universes from destroying each other.
But in “Letters of Transit,” viewers were transported to the year 2036, where two agents named Simon (Henry Ian Cusick) and Etta (Georgina Haig) revived Dr. Walter Bishop (John Noble) to help them fight off the Observers; who took control of our world two decades earlier.
Near the end of the episode, Etta lost Simon to the Amber, but her father, Peter Bishop (Joshua Jackson) and his colleague, Astrid Farnsworth (Jasika Nicole) were reunited with Walter… while the fate of Olivia Dunham (Anna Torv) was uncertain.
Fox has released the first teaser trailer for “Fringe” season 5 (via TVLine), and as you can see below, the Observers storyline is moving front and center for the series’ final season.
“Fringe” season 5 will debut on Friday, September 28.
