[quote][b]Posted by:[/b] ROBERTO jh Cortana is evolved in the sense that she's more sentient than Forerunner Ancillas, who, while more effective, may have lacked personality.[/quote] I'm pretty sure by 'evolved' he was foreshadowing what will be Cortana's metastability - she didn't die at the end of [i]Halo 4[/i]; as Halsey theorised, she'll have found a way to exist in slipspace (having entered with the Didact's armour) and overcome her rampancy. People also seem to be forgetting that she's effectively half ancilla; remember [i]Reach[/i]? That fragment of Cortana you're delivering to the [i]Autumn[/i] is Forerunner. Normal rules don't apply. Cortana will be back, and she'll be better than ever.
