Sci-Fi aficionados are mourning the end of Fringe — one of the most intriguing series TV has ever seen. Described by many as a hybrid of The X-Files, Altered States, and The Twilight Zone, Fringe captured mysteries related to investigative cases, fringe science, transhumanist experiments, and the collision of parallel universes.

In the two-hour finale, the Fringe team faces one last battle against the Observers for the sake of mankind. Will Walter (John Noble), who has cheated fate many times, dodge the bullet? Will Peter (Joshua Jackson) and Olivia (Anna Torv) be reunited with their daughter? And why is Olivia about to load up on hazardous cortexiphan? The suspense is killing us.

There is only one way to find out the answers. Watch the final episode of the series unfold in a two-hour event on Friday, January 18, at 8 p.m. on FOX.
