OK, Fringe fans, did you crack the code? We posted the crazy fourth trailer for the April 20 episode, "Letters of Transit," yesterday and let you know it was embedded with the last clue to a secret URL for a fifth and final clip (other hints were buried in the three previously released trailers). Now we have the complete link and, surprise, surprise, it's not for another trailer at all. It's actually the opening credits to the highly anticipated 19th episode, which jumps out of Fringe's already out-there timeline for a futuristic tale guest starring Henry Ian Cusick. And from what we're seeing in this segment, it's not just a new a whole new Orwellian universe. Someone get Walter Bishop on the phone immediately!

Fringe airs Fridays at 9/8c on Fox.
