I agree with the sentiment but obviously the decision had already been made when they shot the shower scene.
Also agree. Amazing that they had both scenarios in front of them - and chose the dream.
It‘s unclear if it was ever really intended to use a different explanation than the dream.
Some other quotes:
In June a CBS vice president said that a „willing suspension of disbelief“ was necessaryfor viewers to accept Duffy‘s return. In the same month Duffy said that he would play Bobby and not another character.
Steve Kanaly thought that the storyline asks the audience to accept a lot.
Only Duffy, his wife and Katzman knew how Bobby comes back.
Jennilee Harrison received a telegram after the season to disregard the previous which stated her departure from the series (because she died).
Katzman taped several alternate decoys. Hagman hoped that the „Bobby never died solution“ would be used.
John Beck was let go directly after the season.
Writer David Paulsen called the dream solution absolutely perfect.
Priscilla Presley, Linda Grey and Joan van Ark were less enthusiatic about Bobby‘s return for several reasons.
Katzman later said „I‘ll go to my grave convinced that this was the only way to do it.“
Howard Keel called the dream scenario appropriate because the whole season was a nightmare.
Duffy agreed to return for season 9-11 fir 35,000Dollars per episode raise to 75,000 Dollars per episode, a one million signing a bonus and control over the storyline resurrecting Bobby.
