For those interested, FOX has rearranged Fringe's schedule for the last batch of episodes for Season 4.
So, 4x14 'The End of All Things' airs on February 24. Then there will be a 3 week break, and new episodes will return March 23 with episode 4x15 and run straight through until May 11, culminating with the Season Four Finale. Hoping it's not the de-facto Series Finale. I just simply can't lose Chuck and Fringe in one season.
