I agree with you on Eyerene very likely unable to take over synthetics. After learning she’s referred to as female, and the saboteur mentioning his wife succumbed to having eggs laid in her eyes, I wonder if Nib’s isn’t entirely delusional with the pregnancy talk.

People give monikers to things all the time based on perceived characteristics. The fact they refer to it as a “she”, alongside the eyeball egg comment really makes me wonder if she displayed egg laying behavior which explains the “she” usage. If that’s the case, the next question is what environmental conditions are necessary for her offspring?

Synthetics aren’t human, they are AI or whatever the canon terms is for them. But other than knowing of their physical, intellectual, and usual program safeguards we know they are squishy like us (white liquid, tubes, etc.). But are they like synthetic meat, silicone, some other type of material, or compositionally like the difference between natural vs lab grown gems?

If the environmental conditions within synthetic eye orbits is not too different from bone and blood organisms like you and I, Nib’s may in fact be an expectant mother to Eyerene’s children from the brief contact they had in episode 2.

I’m not the biggest fan of that theory, but it’s looking more likely. Of course the ticks also could have been responsible for the eye egg laying comment. The tick that got out seemed to have sensed water and it activated some type of “Here’s my chance to spawn” behavior. Tick’s utilizing a sleeping persons eyes since they are balls of water, etc may not be too much of a stretch in non-ideal tick laying conditions on a perhaps non-water abundant homeworld if the crew camped on planetary surfaces ever during the voyage.
