Editing Fail During Nick & Jen's Final Ceremony
Before Nick starts to tell Jen that he cannot proceed toward a future together, Jen winces and dramatically turns her head, as if she can no longer bare to hear anymore. However, all Nick said to her at that point is she has made him a better man.
The show's editor incorrectly placed the next scene's Jen's reaction shot prematurely ahead of what actually was just said. If you rewind the sequence, you can even see that Nick's head position and mouth movements are out of sync with the actual flow of how Nick's conversation went.
