The Varvax take no outrage because the humans are “uncivilized”, and they are thought of such because they don’t have cytonics. If the humans developed cytonics, becoming “civilized” and continued their violent lifestyle, which seems likely to me as they’re humans, the varvax and all of the allied alliens might be forced to take action.
Yes, but since members of the Defiant have cytonics, humans must learn of them at some point. Based on the scene in one of the scientists (his name is something like Rikolfr) says the activity in Spensa’s “Writellum” section of the brain spiked when near the keel. Due to the similarity of this name to Jason Write’s last name, I’m of the belief that Jason reveals the use of cytonics to humanity.
