We're still not ready to bid farewell to "Fringe," which begins its final season Friday, Sept. 28 at 9 p.m. on Fox. Still, we know all good things must come to an end, and producer Joel Wyman promises that the writers have gone to great lengths to ensure that the ending will be "beautiful and touching and meaningful," so all that's left is for us to sit back and enjoy the ride.

We've already seen a number of thrilling (and frankly, terrifying) promos for Season 5, but Fox has just released stills from the premiere, which give us another glimpse of the Observer-ruled 2036 -- including a few spoilery moments that left us shocked but a little relieved. Click through the gallery below if you don't mind losing some of the mystery for episode 501.
