No mention of Carolyn (Mary) dying ... It would have been nice at the end of the soap Paul would have said something about her or they could of ran pictures of her from her time on the show.
I watched Mary for years and didn't like how the writers had her husband Carl leave GC get amnesia, and end up marrying someone else ........ seemed kind of hard to believe for a strict Catholic family..... Mary was on Y&R 1980 to May 10, 2004 [recurring].
After five years of never seeing Mary, in 2009, Paul was about to marry Nikki Newman. At the rehearsal dinner the night before, Paul's brother Father Todd told the group that Mary was at home and not up to attending, but that she would be there for the wedding. Unfortunately, Nikki called off the wedding, and we never got to see Mary.
remember when .... she was caught breaking and entering into Michael Baldwin's office with Lynne Bassett; charges were dropped, those were the good old days.
Miscarriage caused when breaking up a fight between her sons Steve and Paul 
I want to think maybe Paul would have wanted to pay tribute to her but who knows about the higher ups?
