We are just a few short days away from the final season of Fringe kicking off with "Transilience Thought Unifier Model-11" on Friday, September 25. To tide you over until then, Fox has released an extended trailer that teases several intriguing developments in Season 5, including how Walter (John Noble) may be able to stop The Observers, and a look at the dynamic between Peter (Joshua Jackson) and his grown daughter Etta (Georgina Haig). If you recall, we first saw Etta in the Season 4 episode "Letters of Transit", which gave us a brief glimpse at this Observer-controlled world in the year 2036. Take a look at what's in store for viewers in the Season 5 premiere.
