The show is taken into a new direction for the final season, as you can tell by the episode name. Sadly this decision was for the worst with the sudden cancelation later this season.
Many people now believe that if David had written more for season 4 of Picket Fences the show would have been renewed for a fifth season.
David was very busy this year so he could not find the time to writer for the show as often.
The title of this episode is referring to a new change of direction on the show. From this episode onwards David E. Kelley has little to do with the fourth season.
David E. Kelley did not write this season's premier.
Marlee Matlin is added to the regular cast.
