In this tantalizing teaser highlighting what’s to come on Fringe the show asks fans, “Where will you be when it happens?”

When what happens exactly? What is “it“? Perhaps they are referring to the impending doom (the obliteration of one universe) brought on by the machine + Peter Bishop. Or maybe it’s something else entirely…

Whatever’s going to happening, it’s going down when the sun comes up at 6:02AM. Now how do I know that? In a blink-and-you-miss-it moment, the time “6:02AM” flashes precisely at :12 and then again at :13 in the video above. Sneaky, huh? FOX posted a lengthier promo called “Life and Death” and this video also makes mention of this mysterious time. I’ve embedded the second spot after the break, and I’ll leave it up to you to find the clue.

With promise of another season, I can’t wait to see what the team has in store for the May season finale. Fringe airs Fridays at 9PM on FOX. New episodes return April 15.
