I do not know why folks assume because of mentions of him, that he is alive and well. People do mention dead relatives, recall things to do with them, that is not unusual. I hated that Days chose to have a picture that Shane (in his Stefano disguise) did not remember having been taken, included in the whitewash of Hope's killing of Stefano. I always thought they did a good job with his death. He was dying, knew it, was becoming more and more feeble, so goaded and prodded Hope, knowing she would snap. His final revenge, which is why he was laughing so much. The man was deposited, wrapped up, in a dilapidated building, full of dust and dirt for several days. He was shot several times, so there had to be a a great deal of blood loss, in addition to whatever had him dying in the 1st place.
Stefano is dead. just as Mickey is dead, Shawn & Caroline are dead, Tom & Alice are dead. As much as we would like to live long healthy lives forever, that is not in the cards. Just wish everyone, including the show itself, would just left Stefano rest in peace.
Put an end to DiMeras.....but guess writers today are just no capable of building up a family from scratch any more. Heck, they cannot even keep the Brady family, why worry about DiMera?
