In '137 Sekunden', a man said he can explain why the blackout last 2 minutes and 17 seconds saying that he has a vision about it.
Days after the global blackout, Mark finds an information that someone in German has an explanation to it. In the next "FlashForward", Mark and Janis travel to Germany to speak with an imprisoned Nazi who claims to have knowledge about the blackouts.
An anonymous tip leads Demetri to believe his deepest fears about his future. Meanwhile, Aaron pleads with Mark to help him get the approval to have his daughter's body exhumed in order to re-test her DNA and confirm the identity of the remains.
Called "137 Sekunden", the episode is to air on Thursday, October 8 on ABC.
One of the biggest mysteries in the show is why all people in the world got a vision of their future during the blackout but Demetri did not. On an interview with EW, John Cho who portrays the character said that he doesn't get the answer as much as the audience because he is only allowed to read one script ahead. But he assured that "the clues start to trickle in".
