Title for Reference.
So I was talking with a fellow member about the whole Flood conflict, both with Ancient Humanity and the Forerunners and how the Flood/Precursors returning to the Galaxy may be the ancient evil promoted for the Reclaimer Trilogy. Anyways, the convo eventually lead to the Flood on the Halo's and to the Flood that were already released and fighting the Sentinels within the Sentinel Wall.
I think I heard something about this being explained or hinted towards somewhere, but I can't remember. Does anyone know how exactly the Flood were already fighting the Sentinels on Delta Halo? Where did the mass come from to sustain them on the ring?
Thanks.
Discuss.

The first time you see the conflict is when the Arbiter lands on Delta to retrieve the Sacred Icon. As you play through the level, you see several dead Covenant and Humans along the way. Adding to the fact that 2401 seemed to be going, or was rampant, might have meant that he had released the quarantined flood specimens which would have infected the invaded armies, causing the destruction of the "Zone" which they where housed.
