: Yeah the surprise of the person when saying "compound that kills only
: humans" is odd. If it's just the flood, everyone should know by
: now, yes? But perhaps there's an aspect of the flood perhaps just
: discovered (or just little understood) that allows a controlled
: implementation of the flood spores, a human-directed weaponized flood
: spore? It's curious. But it must have to do with Flood; why introduce
: something brand new and unrelated to anything previously Halo? Covenant
: and Flood arcs are still plenty :P
Well for all need know what's affecting people is some sort of stripped down weaponize version of the Flood, without all the consuming of sentient life in the galaxy side effects. Or not. I'm not inclined to give the line much credence taken out of the whole piece; might have been given such prominence just cause it's a "trailer line".
