The "Have you missed me?" part is her describing how perfect of an ecosystem Halo is. Usually, anything in Halo regarding a "Demon" is the MC, but not in this case. Their was nothing of this sort in Halo 1 guarding the Halo, so it's either in Halo 3 or not in at all. Faith-Blinded Zealots-Covenant Don't waster your pity on them- They are blinded, for they can't see what halo REALLY does, but they won't listen to the humans cause...you know...they're killing each other. Giants- Definetly Forerunner. And yes, I believe the humans are descended from them, it makes sense with the "Reclaimer" stuff. Blurred line on Godhood and Insanity- this is a line about Rampancy. After the AI has been rampant for a while, the become Meta-Stable, and, are essentially, gods in their own sense. However, like 343GS, sometimes they can go a little....crazy.
