All "Smart AIs" go rampant after seven years of life in the halo universe, so cortana will most likely either be crazy or dead come the next sequel if there is one, which disappoints me.
But didnt Halsley explain in the books that AIs could shut themselves down for a certain period of time? Im sure she did.

Watch the scene after the credits if you haven't.
I saw that part.I'm excluding before hand though.I mean I'm just saying I didnt necissarily think it would expectively end like that.
