I had a question concerning the android characters. Vilos Anderien has infrared vision, meaning that he is able to see heat signatures. What sort of heat signatures would an android potentially put off. I think it is fair to assume that certain mechanical parts, such as a power supply, would generate heat, but would the rest of their bodies as well, or would he spot them for what they are right off? Something to consider. After all, the androids appear human. Is it possible that they do so because they are partially biological in their anatomy so far as the external parts go, like in Terminator? If so, he might not be able to notice their true nature after all.
