[quote][b]Posted by:[/b] DonVinzone1 I doubt she's dead. I bet the Librarian has made a copy of her. After all: Cortana offers the Librarian the most complete database of mankind and our history and progress that she can get her hands on in her isolation. Her splitting up in the Forerunner network also leads me to believe there are pieces of her scattered around. Will we see her return in her recognizable shape? Doubtful. Although the glimpse of the "Promethean" AI we've seen in this week's SO episode did look remarkably similar to Cortana... My guess however is that she will play an important background role. Working from within the Promethean/Forerunner network to aid Chief during H5 and 6. With her actions being revealed during H6.[/quote] Seems legit. Maybe her actions would be displayed at the end of Halo 5 to add a second pupose to Chief's struggles in Halo 6, to save Cortana.
