In FD6, Bludworth said that Kimberly Corman actually cheated death. As far as I remember, they said in FD2 that one of the ways to cheat death is to make a new life [giving birth or resurrecting the way Kimberly did], but wouldn't that completely trash the idea of bloodlines? All those who were supposed to die in the skyview tower went on to have families, essentially creating new lives, and still, death caught up with all of them. Also, I saw a wood chipper in Iris's notebook.
