The Grim Reaper Wears a Teflon Coat - S1-E5

Audio problem: In the last scene of the episode Sheridan says to Mr. Sebastian "The morning after the last of a string of murders in the East End." His lips however, say West End instead of East End. The script and initial broadcast used the words East End, but after it was pointed out that this was factually incorrect, the line was dubbed over for all subsequent broadcasts and releases.
