Are the composed versions of the Prometheans and humans we fight on Requiem immune to the Flood's logic plague? I initially thought they would be (being composed versions of organic minds, rather than AI in nature), however I recall Monitor Chakas mentioning something about fear of potential logic plague effects on him in Silentium (I could be wrong though, it's a while since I've read it). If they were susceptible to the logic plague, it seems like a poor solution to the Flood on the original Didact's part.
