I still expect Abigail to come back.I'm just gonna come out and say it. The Vampire Diaries did so many deaths and resurrections that eventually the viewers stopped caring about people dying (and in fact, joked about it) because they knew that they're probably coming back to life soon. It seems that Days of Our Lives, even before this latest news, has decided to adopt this trend as well, so I'm no longer so invested in the deaths of major characters.
It looks like short term, but more than a week or two.
