Having recently read the synopsis of that period, I don't think you should let them off the hook so easily.
In the fall of 1990, Eden was shot and went into a coma, (presumably to allow Marcy time off). Then, she magically awakens for Christmas, and Robert Barr gifts her an emerald which causes her to have memory flashes. In January of 1991 the Dobsons return, and the dinner party marks their first official week of scripts. Eden has a brief flash during the dinner party, but nobody really notices. Then, in February, Marcy's departure is announced. Soon after the whole multiple personality story begins. Prior to that period, it looked like a story of how Eden and Robert were once thieves for thrills. It wasn't until the Dobsons return that the whole confusion about multiple personalities, and Eden's anger at Sophia, became a part of the plot. There may have been a story outline, but one tends to think, given the multiple interviews that Bridget gave about not watching the show while she was gone, that she probably did not feel beholden to the plans of prior writers.
I've been offputting this for centuries so I think since I've got insomnia it's a good time to begin writing this, a soap is dependent of good Characters to keep it interesting but so many of them are forgotten nowadays I thought discussing this with people who have the knowledge to give them a decent page for their Preservation
This one is dedicated to Rachel Davies Fram Cory Hustings from Another World who being a Iconic character for over 32 years never got a Wikipedia page
Soaps are always trying to get some glamour out of Fictional Nobility before you know you'll be seeing Queens, Kings, Princes, Princesses, Ducks and Duchesses and Counts and Countesses so this one is for them
I can think of a few like mr boring etiquette Prince Michael of Moldavia, little rascal King Of Tanquir who young as he was Managed to hold Cecile DePoulignac his prisoner and Let's not forget the royal killer of the English Language Princess Gillian Andrassy or evil Thief Princess Gina Von Amberg
