So in Halo one on the mission where you get the key ( activation index right) guilty spark says something weird he says something about you being in a flesh State but the way he says it makes it sound like he knows someone that you don’t
Do you mean this?
“Protocol requires that I take possession of the Index for transport. Your organic form renders you… vulnerable to infection. The Index must not fall into the hands of the Flood, before we reach the Control Room and activate the installation.”
If this is what you mean then 343 Guilty Spark is just commenting on how the Master Chief is human and susceptible to being infected by the Flood like the marines and Covenant.
I can’t seem to find anything about that from the level transcript. Closest I can find is the quote above, and this:
“These Sentinels will supplement your combat system. But I suggest you upgrade to at least a Class Twelve combat skin. Your current model only scans as a Class Two, which is ill suited for this kind of work”—referring to the armour used by the Forerunners.
