I think I have mentioned in other threads that interviews have definitely led me to the same conclusion about the NBC suits dictating story/actors, etc. to shows. Writers have left prime time shows, even those who created the shows to begin with have left their own show because of the interference. Bill & Susan Hayes talked about the tendency in their book, but just a bit.
NBC thinks that focusing on that "hip, young" audience is the way to go, and the way their sponsors want to go. LOL.
Rumors about recasting Bo have been around a long time. But the show waited too long to explain his absence, and really, still have not. EJ is dead, but, even 6 mos ahead in filming, the show could not make up it's mind if they would recast, so wanted a way to leave the door open, "just in case".
To tell the truth, I would have rather seen a casket switch ala Patch Johnson, then another stupid & dumb injection. Sorry, but EJ was dead for hours. The body begins to deteriorate within a short time.
In my opinion, Stefano wanted EJ buried in his beloved Italy, in the family tomb, so yes, he faked the ashes, etc. for Samantha, and had EJ brought to where Stefano was for burial.
