Corrected entry: At the beginning of the movie, Freddy says that he's been stuck in Hell and searching for somebody for ten years. However, later in the movie, a cop says that they've kept Freddy a secret for only four years. That brings up an inconsistency between the two time tables.

Correction: Freddy never states how long he had been searching, he said "I had to search the bowels of hell, but I found someone." So there was never any conflict in time lines.
