 SPOILER: This episode was originally written without Ed, after  Craig McLachlan (I) (qv) made the decision to leave the series.  The character of Ed was to have died from injuries sustained at the  end of the previous episode. However, Craig McLachlan (I) (qv)  decided to stay at the last minute, and the scripts were hurriedly  rewritten so that Ed is only injured for the duration of this  episode.
