I'm curious how they'll explain the goo working on an android...do we know much about the inner workings of androids in the Aliens universe? Are their organic bits purely for appearance? Does the black goo work on a more "metaphysical" level (i.e. it works on any being with self-awareness)?
Is Engineer tech going to be at least somewhat rooted in known science or is it going to be completely out there in that it might as well be magic to us?
