While re-reviewing Book of Cain once more, I am starting to see there might be just a faint ray of hope for Leah's survival despite the grim, short-live future that may await for her in the cruel-cruel world that is Diablo III.
Reference points: did anybody notice the post-Diablo-mortem fate of both King Leoric's sons from Book of Cain, hmm? What happen to Albrecht and Aiden?
Take those noted reference points, combine that knowledge to what you know of her [Leah's] allege father and seen Diablo's "female form," you might understand what I'm trying to allude too. This could be a painful journey for her yes, but one she might endured. (Hopefully readers can interpret my fan rambling and get the gist of it.) It speculation but I'm bewildering myself! ;)
Maybe no head scars for dear Leah...
