Returns 9 p.m., Friday Jan. 11
In the final episodes of "Fringe," we'll finally get the answers we've been looking for about the first Observer, September, and with them some clues about the integral child Observer, Michael. In a touching moment, we'll learn that Walter (John Noble) remembers bonding with Peter
(Joshua Jackson) throughout the first and second seasons -- memories he'd lost when the new timeline restarted their relationship. We'll also find out that after the deaths of Etta and Nina, one more beloved member of the team will have to be sacrificed
in order to reset time and defeat the observers.
